MAINTENANCE BEST PRACTICE
Reliability Improvements Drive Down Maintenance Costs
An organization must focus on
sustainable results, not just cutting
costs. The following Three case
studies will illustrate.
Results-oriented organizations focus first on the
quality and volume of production throughput,
followed closely by the cost to produce the
required quality and volume. This approach will
improve reliability performance, which will drive
manufacturing costs down.
Most organizations focus more on cutting
maintenance costs, and, as a consequence,
maintenance costs go down temporarily, only to
increase much more than the initial savings. In
addition, reliability goes down, paving the way
for losses that can be substantial. This behavior
and results have been proven many times,
especially in economic downturns. The root cause
of this phenomenon is often shortsightedness
and what the late quality leader Dr. W. Edwards
Deming described as one of the most serious
diseases in American industry: “the mobility of top
management.”
The three case studies that follow demonstrate
what happened in two organizations that focused
on cost reductions and in a third organization that
focused on Results Oriented Maintenance.
Case 1: Cost and head count reduction
The accompanying graph shows a 3-year case study in a food processing organization with an aggressive cost reduction program. A key measure used in maintenance benchmarking exercises was the number of maintenance crafts people and first line managers such as planners and supervisors.
The head count reduction was done through attrition and layoffs. The major mistakes by this organization were:• To cut costs by reducing only the number of employees
and not considering reducing the need for maintenance or improving work processes.
• To focus on number of employees, instead of hours of maintenance work, including overtime and contractor hours.
Case 2: Aggressive cost reduction
The graph for this case shows results at a chemical plant, a high-cost producer in its market, where management decided to do whatever it took to cut costs, mainly in maintenance. When the cost-saving initiative started, market prices for the plant’s products were low and profitability in a short-term perspective was low compared to other plants in the corporation. The fast-paced cost reduction actions included:
• Operations took over maintenance and only did maintenance work that was judged absolutely necessary.
• Planners were laid off and planning of work was discontinued.
• Scheduling was discontinued.• Maintenance prevention activities such as shaft alignment
were abandoned and lubrication was handed over to operators without training and implementation of a documented program.
• The preventive maintenance program was handed over to the operators, without training in what to do or how to inspect. The preventive maintenance inspectors were laid off.
• Shutdown crews were merged with another plant about 1 hr drive from the subject plant.
• Painting programs were abandoned.• Training of crafts people was discontinued.
After realizing the catastrophic consequences of what had happened, the mill took initiatives to bring maintenance to world-class status. Results are very encouraging and the mill is today one of the top performers. Reliability is approaching 94 percent. Maintenance costs have gone up, so has quality production throughput, and manufacturing and maintenance costs per ton are lower.The actions taken to bring maintenance to world-class status included:
• Reinstating preventive maintenance inspectors and revising the preventive maintenance program.
• Bringing maintenance back to a central maintenance function.
• Developing a partnership between maintenance and operations instead of a customer-supplier relationship.
• Focusing on planning and scheduling and front line implementation of these practices.
• Developing employees’ capabilities toward joint goals.• Making capital investments in new equipment and
restoration of worn out equipment.• Implementing front line management action indicators.
Case 3: Reliability improvements first, costs second
This plant manufactures the same product as the plant described in the previous case, but it decided to focus on reliability improvements instead of only cost reduction. This included:• A clearly outspoken and established partnership between
operations, engineering, and maintenance was forged.

MAINTENANCE BEST PRACTICE
Reliability paysReliability improvements increase production
throughput and drive down maintenance costs.
Maintenance cost reduction is a consequence of
reliability performance; it is never the other way
around.
Case 1: Moving maintenance resources to operations and cutting craft personnel
The number of crafts people was reduced by 14.3 percent the first year. After 1 year, 6 percent were hired back. In the same period, contractor spending went up 88 percent. Total maintenance hours including overtime, contractor hours, and in-house hours went up 10.5 percent. Total maintenance costs went up 29.2 percent. On top of that, reliability and production throughput decreased 6 percent. This plant is now investing in hiring and training more maintenance people, implementing lost maintenance practices, and moving all maintenance resources back to professional maintenance management after initially decentralizing maintenance to operations.
• A change was made from a reactive to a planned and scheduled maintenance organization. Less than 10 percent of all maintenance work was planned when the initiative was launched. Ten years later more than 85 percent of all work is planned and scheduled.
• A strong vibration analysis program was implemented. When it started, the average vibration level was 0.23 in./sec. Today it is down to 0.11 in./sec.
• Lubricators were professionally trained. This resulted in better filtration and water removal, better seals, oil testing, and fewer types of lubricants. Cost for lubrication was reduced by 60 percent.
• All rotating equipment above 1000 rpm is balanced dynamically before it is put into service.
• Many equipment bases were improved and equipped with jack-bolts to improve alignment precision.
• Electric motors and rolls in storage are marked and rotated twice a month.
• Alignment training, standards, and execution were implemented.
• Stores inventory and services were analyzed and improved. Service level now stands at 96 percent and stores value has been reduced by more than 30 percent.
• Adherence to preventive maintenance schedules was increased to over 90 percent.
Case 2: Lingering effect of 2 years of cost cuttingIn the first 2 to 3 years maintenance costs dropped from $35 million/yr to $27 million/yr and results were hailed as good. However, reliability started to decline. When beginning this initiative, overall production reliability (OPR)—the product of quality performance, time performance, and speed performance—was 93 percent; it bottomed at 78 percent 6 years after the start of the initiative. At this time the market price for the plant’s products had doubled. The drop of 15 percent in OPR and quality production output corresponded to a loss of over 300,000 tons during some very good years when product could be sold at top prices. Financial losses because of low OPR resulting from shortsighted maintenance cost savings are conservatively estimated to exceed $1.2 billion over a 3-yr period.
Case 3: Focus on reliabilityDuring the first 3 years, maintenance costs increased 8 percent (2.5 to 3 percent/yr). During the same period, reliability as measured by OPR, and consequently also production throughput, increased steadily from a low of 83 percent to 90 percent. Reliability continued to increase to 92 percent. In financial terms, a short-term increase in maintenance costs of about $3.3 million resulted in savings of $17 million annually. The value of increased and sold production represented $18 million annually. Total maintenance costs were reduced by 40 percent. Today this plant survives another economic downturn because of the reliability initiative it initiated and implemented.

Optima Control Solutions Ltd has
successfully completed a full systems
upgrade on a crucial printing press in just two
weeks for a major international manufacturer
of plastic films.
Leading drives and controls experts
Optima was under pressure to meet the
tight deadline when it was tasked by
Renolit Cramlington Ltd to refurbish the
control system on the five-colour Cerutti
Printing Press at its plant in Cramlington,
Northumberland, during the machine’s
scheduled downtime for maintenance.
Renolit’s engineering project and
maintenance manager, John Milne, explained
that the press was vital in the making
of decorative laminates for kitchen and
bedroom doors and UPVC windows. Any
interruption to the printing operation hits the
whole production line at the factory.
Optima’s previous experience of refurbishing
Cerutti Printing Press control systems was
a key factor in Renolit’s decision to choose
Optima to carry out this critical task. It was the
first time Renolit had used the Blackburn-based
company, but the decision paid off handsomely
as the refurbishment of the Cerutti Printing
Press was completed within the two-week
deadline and on budget.
Mr Milne said: “We recognised Optima as a
very capable outfit but it was a tricky project
and the pressure was on them to get the
machine up and running as soon as possible.
Optima did a great job and provided an
excellent back-up service. They coped really
well and I would certainly use them again.”

Kawasaki Cleans Up Pump Finishing Operation with AirBench
Haydon Kerk Motion Solutions Introduces the IDEA™ Stepper Motor Drive Module with RS-485 Communication ProtocolWATERBURY, CT – The IDEA stepper motor drive platform now has the capability of communication using an RS-485 data protocol. The RS-485 protocol overcomes the limitations of other drive communication methods making the RS-485 IDEA drive module perfect for industrial applications.
The main advantage of using the RS-485 protocol, especially for industrial equipment such as stepper drives, industrial motor drives, and servo systems, is the ability for long data transmissions while exhibiting excellent immunity to electrical noise. The RS-485 protocol utilizes “differential” signal lines for limiting common mode noise coupling and twisted pair cabling for cancelling out induced noise current.
This allows IDEA devices to communicate over a network of 1000ft without the need for termination resistors. The system architecture
also allows up to 256 addressable device nodes. An industrial controller can send commands to all the drives at once, or each drive can be controlled separately when assigned a unique identifier, a number between 0 and 255.

PUMP MAINTENANCE
OSB is recognised as an innovative, environmentally sustainable timber-based material for both structural and non-structural building applications and is manufactured by compressing strands of wood with resins at high temperature to create strong and versatile panels. Originally gear pumps were being used to deliver the resinous glue into a mixing chamber, where it is sprayed onto wood fibres in the early stages of the manufacturing process. Chosen for their high pressure capability, these pumps leaked persistently through their mechanical seals causing damage to them when hardened resin became trapped between closely meshing gears. This resulted in the need for the pumps and gearbox to be replaced three times on one month. The installation of a Hydra-Cell pump at this stage of the process immediately solved the problem by providing reliable, high-pressure pumping of the resinous glue. The sealless design of these pumps means no dynamic seals to leak, wear, or replace and their spring-loaded, horizontal disk check valves enable the pump to process liquids which contain particulates up to 500 or greater microns in diameter
without problems. Following 6 months of trouble-free operation, the second pumping system was installed on the process with the same successful results for the Oriented Strand Board manufacturer. The range of Hydra-Cell pumps covers flow rates from 0.4 lit/min up to 128 lit/min and pressures up to 172 bar, providing repeatable and accurate output. They can handle dirty liquids and liquids with particulates and because they are sealless by design, leak-free, self priming and can be run dry, they are also ideal for cleaning (CIP) applications. Other applications include; machine tool cooling, reverse osmosis & separation, spray drying & abrasives, paper mill applications and oil production and refining.
Sealless Pumps Help To Solve ‘Sticky’ Problem
Pumping resinous glue at high
temperatures presents a sticky
problem for certain types of pump,
especially when there is an added
complication of the glue containing
particulates. This challenging pumping
application is part of the process
of manufacturing Oriented Strand
Board (OSB) a timber based building
product which is similar to plywood.
However, Hydra-Cell sealless positive
displacement pumps, available from
MICHAEL SMITH ENGINEERS have
proved to be successful on this
application, where other types of
pump have failed.

PUMP MAINTENANCE
Pump servicing, repair and refurbishment is a mainstream
activity for AxFlow (www.axflow.com) and through its
Service Base in Huddersfield it provides pump users with
a wide range of facilities, including supplying and fitting
mechanical seals and the specialist Belzona coating
service. When called in to provide both on-site or off-site
maintenance and repair, it is standard procedure to examine
the pump in detail and to discuss with the customer the
application and operating conditions. In this way the
Company’s engineers are able to provide a wholly effective
solution to the problem regardless of the age of the pump
and to give a guarantee on its work. Where feasible,
remedial work is carried out at the customer’s premises and
typically this will involve identifying the problem if there has
been a pump failure.
Externally the pumps may look to be either in a reasonable
state or not worthy of being rescued. A thorough
examination of the pump in its operating environment will
reveal the cause of the failure and establish whether or
not the pump can be repaired in-situ. AxFlow’s engineers
have a check list of actions that are adhered to during the
disassembly process and it is this procedure that is crucial
to identifying where problems lie. The Company goes as
far as to photograph every action of the stripping down
procedures as this allows component appraisal. Using this
visual data is deemed essential when it come to making
recommendations as to the best course of action to be
taken.
According to Tom Cooper, Service Base Manager, the
goal is to get the customer’s plant back up and running
as quickly as possible, but not at the expense of creating
further problems that might arise in the future. Pump
replacement may at first seem the easiest option, but this
can be costly for the customer and may not always be
the best long term solution. This approach is illustrated by
projects undertaken where the actual pumps in service
were no longer manufactured. Two of the latest restoration
projects have involved a 42-year-old Allen Gwynnes 36”
intake/33” discharge cooling water make-up pump for
a power station in the East Midlands and a 46-year-old
Vickers impounding pump in Hull docks.
Weighing in at around 5 tonnes, including the 600kg 30”
impeller, the Allen Gwynnes DESC pump was installed when
the power station was first constructed in the 1960’s and is
one of three pumps extracting water from the adjacent River
Trent. The scope of the service work included stripping the
pump down and performing a complete dimensional check.
Remedial work involved replacing the impeller wear rings
and rebalancing the whole rotating assembly.
AxFlow also took the opportunity to convert the upper
stuffing box to a split semi-cartridge mechanical seal in
order to allow easy replacement without there being a need
to remove the motor, bearing and coupling. The lower
stuffing box was also converted to an un-split cartridge seal.
“Historically, the gland leakage led to bottom bearing failure
and required constant maintenance to keep the bearing in a
Turning Old Into NewIt is inevitable that over the long term pumps will display signs of wear because it is almost impossible to design a pump that is free from operational deterioration. Wear will have an adverse influence on the performance of the pump, causing mechanical losses, leakage and energy (hydraulic) losses. Components most likely to be affected are bearings, mechanical seals, wear rings, rotating elements and the shaft. Then there is the matter of the internal surfaces which can be subjected to corrosion and erosion by the pumped fluid (Fig. 1).

usable condition,” reports Mark Redgrove, AxFlow Technical
Support Manager. “We reassembled the pump with new
bearings, casing wear rings, fasteners and gaskets before
filling it with (a lot of) water to check the integrity of the
seals. Once all the tests were complete we painted the
pump and organised a fast delivery to site (Fig. 2).”
At Hull docks, the Vickers pump is employed around high
tide to maintain the dock water level. Having removed the
pump from service, it was clear that a full overhaul would be
required, this necessitating the replacement of the cutlass
bearing and shaft sleeve, refurbishing the mechanical seal,
reconditioning the Michell bearings and installing a new
GRP bell mouth because the original one had suffered
severe damage from cavitation. In addition, the impeller
was re-tipped, machined and balanced and all the internal
surfaces coated with Belzona to stop corrosion (Fig. 3).
“Having the facilities to apply Belzona coatings provides us
with a considerable advantage when we take on challenging
pump refurbishment projects,” comments Mark Redgrove.
“These coatings not only give excellent protection against
corrosion, erosion and cavitation, but enhance the hydraulic
performance of the pump which in turns leads to higher
levels of operating efficiency. As a result, our coatings
service is now becoming an integral part of the AxFlow
proposition.”

Saving Water In The Process Of BrewingVacuum pumps within the brewing and bottling process are often far too greedy where water is concerned....

When challenged with this imposition,
Shaun Hampson gave his view from the
Global vacuum brand of Sterling-SIHI.
Brewing processes, are actually quite demanding, which
takes away some of the simplicity associated with the
selection process. Foaming and product carry-over are
common-place in such a process that often attracts a
sanitary/hygienic classification.
When process efficiency is added to the equation, then
the criteria issued to the vacuum equipment suppliers
surrounds:
• 30mbara - 1014mbara pressures
• Tolerant to foaming and liquid carry-over
• Highly reliable
• Efficient, and
• NO water consumption
Generally, it is energy and waste that feature heavily
in the total costs of ownership (and operation).
Consequently, it is these aspects which ought to be
at the centre of all brew-house, and bottling vacuum.
Although this may seem obvious, the reality is sometimes
different when brewers are faced with multiple equipment
suppliers each offering varying technologies at a broad
range of prices.
Ejectors, eductors, liquid-ring vacuum, lobular-roots,
totally dry vacuum, and other products are only the
start of product choice. Their integration together
with vital ancillaries makes all difference to operational
performance alongside reliability, waste, and energy
efficiency. For instance, basic separator design based
on operational experience can have a dramatic influence
on water saving.
For almost 100 years, SIHI have been developing,
manufacturing, and supplying the spectrum of vacuum
and centrifugal pump equipment destined for some of
the World’s biggest breweries, distilleries, and contract
bottling sites.
So, is there a real solution? Ultimately, the answer to
this question lies with System Life-Cycle assessment
following the common theme:
17engineeringmaintenance.infoOctober 2011
Colin Simpson, Sales Director at UK distributors, Billingham-based Tomlinson Hall Ltd, commented, “Richter Pumps are renowned for their innovative magnetic drive and mechanically sealed, plastic-lined pumps for difficult corrosive and hazardous fluids and have become the standard within the European chemical, petrochemical and pharmaceutical industries.”
“However, they have identified a gap in the market for mid-range pumps which previously would have necessitated the use of a higher specification model than was actually necessary. The new RSI and RSA
range of mechanically sealed process pumps has therefore been developed to meet the standard needs for highly corrosion resistant PFA lined pumps at a competitive price.”
Both the RSI (ISO/DIN code compliant) and RSA (ASME/ANSI code compliant) pumps incorporate PFA lining to provide the highest chemical resistance at temperatures from -30° C to 150° C and full FDA conformity. These mechanically sealed process pumps can also handle liquids containing solids and have flow ranges from between 0.1 - 120m3/hr with delivery heads up to 100m.
A major feature of the pumps is their low life cycle costs, designed specifically for ease of maintenance with a wide open lantern design for full visibility and easy access to the mechanical seal area. The pumps are considerably cheaper than mechanical seal pumps made of corrosion resistant metals (titanium, nickel etc) and have a larger pressure and temperature range than full plastic or partially armoured pumps.
Lutz Rosin, Marketing Executive at Richter Chemie-Technik GmbH, commented, “The new range compliments rather than competes with Richter’s existing range - for larger flows, higher temperatures and specific applications, the Richter SCK or mag-drive MNK series may well be more appropriate, but the market’s reaction to these mid-range pumps has been very positive as they incorporate all the high quality design that Richter’s products are known for, but at a more economic price that offers superb value for money.”

PUMP MAINTENANCE
18 engineeringmaintenance.infoOctober 2011
Resistance Temperature Detectors or Resistive Thermal Devices (RTDs) are wire wound and thin film devices that incorporate pure metals or certain alloys that increase in resistance as the temperature increases, and conversely, decrease in resistance as the temperature decreases.
RTDs are similar to thermocouples in that they convert changes in temperature to voltage signals by the measurement of resistance. As an RTD becomes hotter, the resistance measured on its element becomes larger. As the RTD cools, the resistance becomes smaller.
The Platinum Element RTD
The most commonly used type of RTD element is Platinum. These versions are often referred to as PRTs or PRT100s. Platinum elements are popular because they can be used over a wide range of temperatures and also provide fast response times. Platinum’s coefficient of resistance is almost linear, which means that by using a platinum element, resolutions of +/- 0.1 deg C or better are possible.
PRTs are gradually replacing the use of thermocouples in many industrial applications below 600 deg C, due to their higher accuracy and repeatability.
The current international standard which specifies tolerance, and the temperature-to-electrical resistance relationship for platinum resistance thermometers is IEC 60751:2008. By far the most common devices used in industry have a nominal resistance of 100 ohms at 0 deg C, and are called Pt100 sensors (‘Pt’ is the symbol for platinum). The sensitivity of a standard 100 ohm sensor is a nominal 0.385 ohm/°C. RTDs with a sensitivity of 0.375 and 0.392 ohm/°C as well as a variety of others are also available.
Other Elements
Other more cost effective elements can be used in RTDs. The most common of these alternatives are copper and nickel. The advantage here is that the RTD will have a reduced manufacturing cost and will have a lower replacement value. However, the drawback is that these elements have more restrictions on the range over which they can be used due to non-linearities in the Resistance versus Voltage curve. Also, problems of wire oxidation are known to occur when copper is used as the element.
Why choose an RTD?
One of the technical advantages of using an RTD is that it provides a very stable output for long period of time. Other benefits include ease of recalibration and accuracy of readings over a relatively narrow temperature range. When compared to thermocouples, the disadvantages of using RTDs are: higher sensitivity to vibration, smaller overall temperature range, and a greater initial cost.
Prolonging Life and Eliminating Measurement Errors
To achieve the maximum life from a Resistance Temperature Detector, it is recommended that a protective well and terminal head be used. The well serves to protect the RTD from damage by the gas or liquid being measured. Protecting wells are typically manufactured in stainless steel, carbon steel, Inconel or cast iron. The wells are designed to operate in temperatures up to 1,100 deg C.
To eliminate measurement errors, it is necessary to compensate for the length of lead wire used to connect the RTD to the readout. The calculations to correct this are relatively straightforward. Three-wire and four-wire designs are also available that help to minimise these types of errors.
Laboratory Accuracy with Industrial Ruggedness
Platinum resistance temperature detectors are used for interpolation between the IPTS-68 fixed temperature points of ice and antimony (0 deg C to 630.74 deg C). They are generally used where accuracy and stability are most important. OMC’s approach to RTDs will bring +/- 0.05 degrees laboratory accuracy to the toughest industrial processes – without any special handling considerations.
OMC has combined the inherent accuracy of a precisely wound Platinum resistance element with AeroPak® compacted ceramic insulated cable. The result is a low cost yet rugged sensor that will withstand factory handling, whilst retaining the stability required for today’s precision process control environments.
Time response characteristics
The response of an OMC Resistance Temperature Detector is defined by two noticeable characteristics when exposed to an instantaneous (step) change in environment temperature. These are:
(a) Time Constant: The time to reach 63.2% of the complete step change in temperature.(b) Response Time: Time to reach within 0.5% of the final temperature in a step change. This is approximately equal to 5 times the time constant.
The response of a temperature sensor to a step change in environment temperature tends to follow a second order differential equation. However, this is approximate, since if the mass of the sensor is small in relation to the mass of the fluid passing over it (as is the case with a liquid), the response may approach a first order differential equation.
Selection/Matching
Completed probes can be matched in pairs to the nearest 0.01 ohm at 0 deg C for differential temperature measurements to 0.05 deg C.
Completed probes can be supplied with selected ice point resistances within a narrow band to eliminate the need for compensation in indicating circuits.
Latest development
In the last few months, OMC has completed the development of a brand new high temperature platinum resistance thermometer for industrial applications. The new Ceracoil W86 is able to measure very high temperatures of up to 660 deg C using a platinum RTD element.

The steel plant, based in India’s eastern region, has a
very long steam network measuring approximately 16km.
Comprised of a high pressure system with a pressure rate
of 63 bar and temperatures of 480°C and a low pressure
system with a pressure rate of 15 bar and temperatures
of 300°C, the network has approximately 500 steam traps
fitted along the length of the pipework.
Despite having tried thermodynamic traps, and in some
places inverted bucket traps, from all of India’s five
steam trap manufacturers, it was found that none lasted
longer than six months. The plant then imported traps
from Germany and Japan, and although the life of the
mechanical trap increased, they still only lasted between 6
months and a year.
Looking for a steam trap with longevity, the plant contacted
Zenith Marketing & Consultants, a company specialising in
industrial energy saving products, about the award winning
GEM venturi orifice steam trap. Following a number of
meetings a bucket test was carried out on the steam line to
evaluate the GEM trap’s performance. The evaluation was
carried out over a 30-month period and after the protracted
trial it was found that the GEM traps were still working well.
This provided the plant with conclusive proof that the GEM
venturi orifice steam trap offers ultimate reliability.
Fitting GEM steam traps has resulted in the plant achieving
energy savings by preventing steam leaks from failed traps
and providing added efficiency. In addition the plant has
also saved costs on replacement traps and maintenance,
eliminated trap inspections, prevented pipe damage that
destabilises the steam distribution system and improved the
safety characteristics of the steam network.
Commenting on the installation Subhas Naik, Director of
Zenith Marketing & Consultants said: “We have installed
15mm and 20mm sized traps, which have helped solve the
steam network’s many problems. The plant is delighted
with the GEM trap and has made it its steam trap of
choice”.
Instead of utilising a valve mechanism to close off steam
for maximum energy and water conservation, the highly
efficient GEM steam traps use the venturi orifice design to
effectively drain condensate from the steam system. GEM
steam traps are available in a wide range of sizes for a full
cross section of applications. The hardwearing GEM steam
traps are manufactured from corrosion resistant stainless
steel and are guaranteed for 10 years, eliminating the costs
associated with regular repair or replacement of other types
of traps.

Systems for directly replacing ‘mobrey style’ float switches
with fail-safe, self monitoring tuning fork switches with or
without chambers are also available.
VEGAMAG also employs an MLI, where the magnetic
float indicator system displays the level locally - no power
supply is needed. This is used in combination with a VEGA
radar transmitter, which also measures/ detects the level
inside a connected or shared chamber. By using different
level techniques, this offers alternative measurements and
additional diagnostics to provide ‘safety through diversity’ in
one installation.
Whatever the configuration or requirement, VEGA supply

According to the International Energy Agency most companies use up to 50% more heat energy than they need to as a matter of course. Yet, with the right technology, most, if not all, of that heat is recoverable says Alfa Laval. And the volumes involved wouldn’t be insignificant. Some authoritative sources claim that the amount saved would be equal to three times the total current output of the global nuclear industry. Alfa Laval has produced an informative, fact-filled booklet. Waste Heat Recovery - Optimising your energy system, that spells out the potential benefits; highlighting where energy is most likely to be wasted; how to recover it and
recycle it to reduce energy consumption; how to profit from greater energy efficiency and how to transform waste heat recovered from one source into productive heat for another.
Don’t Think Of It As Waste – It’s Energy In WaitingAll over the world companies and
governments are investing billions to
develop new sources of energy in the form
of biofuels, solar and wind power and
traditional fossil fuels. Yet, according to
heat transfer specialists, Alfa Laval Limited,
all of them could save time – and money
– simply by getting much more out of the
energy they already consume.

STEAM TRAPS
By preventing steam escaping into the brewery’s condensate recovery systems, the new steam traps have also improved the site’s environmental image by eliminating visible steam emissions. “You used to see plumes of steam exiting the plant, but now that’s all stopped,” says Colin Walton, Senior Engineer at Marston’s Brewery. The impact was instant, with the quantity of escaping steam visibly reducing as more and more of the steam traps were replaced. “I used to tell the fitters that I’d know they’d done their job when steam stopped coming out of the condensate tank in each section,” he says. Stainless steel sealed inverted bucket steam traps from Spirax Sarco have replaced about 70 old steam traps ranging from 10 to 40 years. The brewery opted to make the change en masse, rather than checking each steam trap individually for faults. “Price and quality were the deciding factors in choosing Spirax Sarco, but they also delivered great local support” says Mr. Walton. The new steam traps were responsible for the lion’s share of the savings, but Marston’s also took the opportunity to remove any trap bypasses from the steam system at the same time. Bypasses are often

Aimia Foods has won numerous awards over the
years and a tour round their plant shows why it has
received such honours. For example, many years
ago, the Aimia Foods Continuous Improvement
team needed to persuade staff to segregate waste
so put in place an entirely robust procedure. They
didn’t just provide colour coded bins; they replaced
the white floor tiles that the bins sat on with colour
coded green and brown ones that matched the
bins, ensuring everything was easily identifiable and
placed in its correct location. This was Kaizen, or
‘change for the better’, implemented effectively and
with high levels of success.
Unfortunately, manufacturing in 2011 isn’t all about
success. For many manufacturers stress levels are
increasing to danger levels. No one can be really
sure where the debt situation is leading. If it wasn’t
so serious it could be seen as amusing for the
Americans with $14,708,551,833,446 of debt (at
8:58 GMT 03/10/11) to be lecturing Europe on our
own debt crisis.
It’s against this background that I thought I’d
provide some light humour by way of a ‘tongue
in cheek’ review on how not to run a Continuous
Improvement Team. Unfortunately it is a tale based
on a true story, but please allow for some poetic
license.
Here we go... “Carry on Kaizen”:
Carry on KaizenI had a very pleasant lunch at the Best Factory Awards last Friday; it’s good to see manufacturing in the UK is still alive and making good progress. My old friend Patrick Mroczak, Operations Director at Aimia Foods, won lots of awards as usual. First in three categories and a ‘Highly Commended’ is exceptional by any standards, especially given the professional scrutiny and site visits by the Cranfield judges.
Dear Boss,
‘The Blond’ has been reading those lean books again; either that or the new £1,500 a day lean consultant has suggested we may be able to improve the plant if we implement ‘measurement processes’.
Totally unnecessary given that each day we have orders to fill, and by late evening, often before midnight, we finish most of them. OK, the plant supplier did rate the equipment at single shift for our output,
27engineeringmaintenance.infoOctober 2011
OEE
Ok – so this is a slightly exaggerated account of
a poor Continuous Improvement programme that
has a low level of engagement and is lacking the
basic foundations for success. But often in times
of stress and uncertainty, the basic Measurement
and Kaizen procedures are overlooked for more
adventurous money saving tactics that look good
on paper, but fall short when they aren’t embedded
into the organisation and sustainable. When the
pressure is on, it’s a good test of the basics; do
the plant, people, and process cope, or does
everything, from resourcing to product, start going
wrong?
Saying that your team or organisation is running the
latest initiative is not the same as actually practicing
(and then honing to perfection) the new procedure
or process. The ‘doing’ and ‘checking’ parts of
the ‘acting, planning, doing, and checking’ cycle
are important, and the difference between ‘lip
service’ and ‘award winning’.
and we sometimes have to flood the plant with agency staff, and pay extra overtime, but not for every order. And yes, we do get a lot of customer rejects, but ‘The Blond’ is almost over the £100k fine we got from that S&M supermarket because we got the date code wrong...
I think we do pretty well; our engineers may not appear to do much but they really motor when we have a breakdown, and Roy is brilliant at temporary repairs to get us to the end of the shift. Malcolm did say, letting everyone leave when the orders complete is a shame as then no-one is around to make a permanent fix, but I’m not sure that’s critical, and you should see the team spirit down the pub after work.
Talking about agency staff, the other day, this guy, really, and I mean really, hit the fruit pie line feed conveyor with his fork truck. It took Roy and his lads seven hours to get the conveyor back into shape. ‘The Blond’ went ape and issued final warnings all round. Then the buck passing started with Training having the final say; apparently he had the FLT certificate but I heard it was for a Massey Ferguson. Really, how hard can it be to drive an FLT?
Someone said ‘The Blond’ should spend more time down on the plant; maybe see some of the problems. Better kept upstairs I reckon; less shouting and it means that no one sees how bad it really is on the shopfloor.
So, this measurement thingy, yet another new idea we’re not too worried, we buried the last ‘initiative’ in double quick time. Good job this lot never follow anything through.
Anyway, must go, customer audit tomorrow, better go and paint something.

From anti-slip surfaces, through to the use of lineage and demarcation zones to signpost people safely around a plant, Flowcrete floors are key to the smooth and functional running of manufacturing and processing areas.Now the subject is explored in detail by Flowcrete UK at the Get More From Floors online portal, available at www.flowcrete.co.uk/campaigns/get-more-from-floors Pulling together a variety of content, the Get More From Floors resource centre shares Flowcrete’s 30 years’ wide-ranging experience and flooring expertise to help plant managers make informed decisions about their flooring requirements. Get More From Floors, Get More Safety is the third of six subjects being explored throughout 2011 under the campaign, following on from the issues of floor durability and floor hygiene. Specific floor safety information is located at www.flowcrete.co.uk/campaigns/get-more-from-floors/get-more-safety Alan Dean, Managing Director of Flowcrete UK, said: “According to the HSE, one serious slip accident occurs every three minutes in the UK – most of which occur on a floor contaminated by water, grease or other substances.“Health and safety is a major concern faced by industrial manufacturers and, with this in mind, we have developed a number of flooring solutions to help reduce the risk of slips, trips and other accidents in the workplace - as well as improve workflow management to eliminate these problems at ground level..“Our approach includes anti-slip floor finishes with an adjustable profile to suit client’s individual requirements.“Flowcrete’s team of flooring experts has developed the most advanced range of anti-slip solutions, with systems based on graded aggregates laid between coats, built into the resin matrix or scattered on to the surface of the floor. “The floor surface can be fine turned to meet the balance between slip resistance and cleanability, to ensure a fit for purpose flooring system is specified, suitable for either wet or dry processing areas.“Floors can also reduce risks within the industrial environment by being used as a platform for efficient workflow management, through the principles of 5S and lean manufacturing. “Bright signage, demarcation and instructional patterns can be incorporated at ground level to outline the different zones – marking out walkways and aisles, loading back and stacking areas, and other areas exposed to potential danger. “
Many of Flowcrete’s industrial flooring systems can be graded for positive slip-resistance - including Flowcoat SF41, Flowcoat LXP, Deckshield, Flowfresh HF and Flowcrete HF - to ensure a safe platform underfoot. Flowcrete UK’s latest innovation, FloorGraphix, allows the rapid installation of floor signage through the use of a printed graphic mesh sealed into the floor using a fast cure MMA resin. Colourful demarcation and signage can also be created through virtually all of the industrial flooring specialist’s systems, with a colour palette including a number of vibrant, high visibility shades to achieve maximum impact.Flowcrete’s extensive product offering also includes the industry-leading Industrial Floorzone concept, unique to Flowcrete UK.This system delivers the damp-proof membrane and high strength Isocrete floor screed, topped off with a performance resin floor finish – all from a single source and installed by Flowcrete’s approved contractor network.Flowcrete has vast experience within the industrial flooring industry - carrying out projects for Blue Chip clients including Bentley Motors, the RAF and BAE Systems - backed up with best in class customer and technical support services.

Most of you understand what I mean by budget jail. In fact, you are probably in the process of trying to pick the lock. For those who don’t know what I mean, I’ve listed some signs of what a budget jail look likes:
1. The maintenance budget isn’t built from scratch (zero-based budgeting) each year to consider all major expenses for the coming year.
2. The maintenance budget is, more or less, an arbitrary number (often last year’s budget less X percent) that must be reduced each year regardless of equipment condition.
3. Top management has little understanding for equipment overhaul and major maintenance cycles. Many cycles aren’t annual or more frequent. The cycles for equipment repair and overhaul are often two, five or 10 years. This can create performance spikes.
4. You never break the budget for planned investments, but the budget is often broken due to so-called unforeseen equipment repairs. The plant culture seems to indicate that equipment breakdowns are a valid excuse for breaking the budget, but investments are not.
5. If an investment creates a significant profit for the company in the long term but it breaks the budget for the current year, the investment will be denied.
Do you recognize your plant in the points above? If so, I can tell you that it shouldn’t be that way, and that we must convince top management how to improve reliability. Continuing to preach the reliability gospel is good. But, is there something we can do to break out before we get the whole company sold on reliability? I think so.
BREAK-OUT STRATEGY
If you are in budget jail and have tried to get out by preaching reliability to the people above you but have made little headway, I have a plan. It will test your belief in that a focus on reliability works. Please note that if you are well on your journey into reliability excellence, this plan will not be as useful to you, but it may still work in focused areas.
The idea is simple but requires courage. There is a budget allotted to your plant and/or area for the year. The plan is to break the maintenance budget (assuming it is needed) in the first quarter but regain the lost money with better reliability by the end of the year. You must be the judge in how much you can break the budget in the first quarter and still sit in your chair!
In November/December, you will start performing detailed equipment inspections of your plant and/or area with your best maintenance people using basic inspection tools - flashlights, infrared temperature guns, stroboscopes, vibration pens and industrial stethoscopes.
If you can, create a team of the best operator and maintenance technician you can find for the inspection rounds. Have the inspectors report back in a meeting where both operations and maintenance management are present. This action alone has merits.
The found problems need to become work requests and prioritized. Work closely with operations to establish a meaningful priority system. The total cost of the potential breakdown must be considered, not just the maintenance cost. The key parameters to consider are the same as with any maintenance job:
1. Failure developing period: How long will the equipment last before breaking down?
2. Consequence of potential breakdown (safety, environmental, lost production, damages, repairs, etc.).
3. Risk that the breakdown actually will happen.
Along with the inspections, try to stop all break-in work that isn’t an emergency. A maintenance department can free up 10 to 30 percent of its resources by stopping these honey-do jobs.
SUMMARY
Start doing detailed inspections in late 2011 . Prioritize the problems found and fix them even though you may have to break the budget early in the year. Work with operations and maintenance to get rid of non-critical break-in work to free up resources and/or save money on overtime and contract work. If you prioritize the repairs correctly early in the year, you will reduce maintenance cost through better reliability later in the year.
A Plan For Breaking Out Of Budget JailI wrote this column for those who want to
improve equipment reliability but feel as if
they are stuck in “budget jail”. Assuming your
fiscal year starts January 1, November and
December is the time to plan your jailbreak!

With the high cost of downtime, more and more companies are looking for time and cost-saving alternatives to replacing damaged assets. Belzona offer a simple, cost effective solution to securing leaking pipes.
In September 2011, application services division, Belzona Technosol Limited successfully stemmed a gas leak on a 24 inch cast iron pipe at a steel works in Teesside. The pipe was the gas main between the coke ovens and the power plant and required an immediate solution.
The leak was detected and once excavated a crack of 25cm length was found to be the cause. Belzona 1121 (Super XL-Metal) was selected due to its extended working life, to pack the gasket and to create fillets on either side of the flange. A three layer wrap repair was then completed using Belzona
1121 and Belzona 9341 (Reinforcing Tape), ensuring a long lasting and reliable repair.
The preparation, application and cure were completed within 2 days. The gas main was then reopened and tested at full pressure to the absolute satisfaction of the client.
Steel Plant Back On Line With Belzona WrapPipework suffers from many different problems
including erosion-corrosion, impact damage,
adverse weather conditions and abrasion.
Conventionally, problems such as these may lead
to the entire system having to be closed down and
drained before any repair process or replacement
can begin.

any impact on operation or production and I welcome the opportunity to be part of a team whose business it is to maximise the safety and accuracy of this process.”
IRISS inspection ports and infrared windows are becoming immensely popular in the UK and naturally Patrick is looking forward to working with UK customers to create new and safer inspection routines. He is also responsible for market development throughout the EMEA region which is served by a comprehensive network of IRISS distributors and agents.

Managing Director of leading UK electronics design and manufacturing consultancy, Mutech Ltd, Colin Cameron is one of only two ABMEC representatives on the prestigious committee.
Colin Cameron explains: “As part of the IEC the L6/10 is responsible for issues relating to the safety of electrical and mechanical equipment used in hazardous areas (the IECEx scheme) across a wide range of industries, from oil and gas to mining and landfill.”
L6/10 is the sole route for UK input into the IECEx scheme. In addition it is a forum for interaction with BIS etc on European concerns on ATEX and similar issues.
Colin Cameron continues: “It comprises manufacturers, users, certification and government bodies, offering the UK perspective to the international committee.”
The nomination is an acknowledgement of Colin Cameron’s
wealth of electronics expertise, particularly with intrinsic safety. He continues: “I want to take an active role, principally by looking after the interests of equipment manufacturers. My long term goal will be to contribute to the development of international standards and to work towards global harmonisation.”
L6/10 balances the needs of various vested interests. On the one hand it prevents dangerous products from entering the market, whilst recognising the legitimate needs of manufacturers and users to introduce new products and techniques.
Colin Cameron’s selection by ABMEC closely follows Mutech’s appointment of Mark Pitts as Design Manager at the Manchester based company. Mark also has extensive experience in participating in committees responsible for international standards for electronics.

UK Service Manager Chris Norris said “We have been very successful with the product claiming a significant market share for the free standing sales. We took advantage of the very low warranty defect rate and offered a simple “no quibble” warranty extension to 3 years and of course we hoped that the designers would not get over zealous about value engineering and replacing what I regard as key components in the product’s reliability with lower cost items which might affect the product’s integrity. We have all seen this happen!” Norris goes on to describe the changes made, “The product only needed some tweaking and we were pleased to see that the controllers were brought up to a high standard, the smaller units having a relatively simple display but doing all the necessary tasks including controlling the BEKOMAT level sensing drain, also allowingthe drain test to be carried out from the control panel. Obviously I am always pleased to see service indication on products particularly very reliable products which can get abused because of this virtue. On the 3 phase line we have
scroll compressors fitted from RA1080. This helps keep noise and vibration down and allows a simpler connection, all helping to keep costs down. We have some new features such as Advanced Service Warning, Advanced Fan Control which allows the fan to run at 50% speed saving energy and helping to keep a constant dewpoint. All alarms and operating data are stored in the system to help prevent failures and if they occur to quickly diagnose the cause of the problem. The refrigerant has also been changed to R407C which has a significantly lower GWP (Global Warming Potential) than R404a.Chris Norris summarises by saying “We in the UK are very satisfied with the new range. We believe that we will get even stronger in the market by offering what customers want, reliability, performance to the specification, connectivity, and ease of maintenance via good information from the control system. We are confident that our DRYPOINT RA range will give customers the lowest cost of ownership and publish our pressure drop and total power input for customer scrutiny. It’s a pity notall do this. In fact some of our competitors publish neither and some just the power. It is really important to understand that the upfront cost of the product is only half the story! BEKO stock these products and offer them at a price that is good for such a quality product. The best just got better!
The Best Just Got Better!BEKO TECHNOLOGIES are pleased to announce
the launch of the new range of DRYPOINT RA

Standard air compressors are designed to operate continuously at full capacity. However depending on the application, the need for compressed air varies significantly. Research has shown, that on average, only50-70 % of the Compressor capacity is utilized. HERTZ FRECON models within the Variable Speed Controlled Compressor Series, give you the advantage to reduce energy costs by up to 35 %. Figures show a comparison of energy consumption between same sized ON/OFF-load compressors and HSC FRECON Compressors. This consists of cost in 5 Years, compressors running 4000hours/year with an average load ratio of 60% “on load” and 40% “off load” with today’s high energy costs.
“ Hertz Kompressoren has tailored its HSC Frecon Series Screw Compressors, the ideal choice for all kinds of industry and applications.

The 621B40 works with online or portable monitoring systems to provide reliable and effective vibration monitoring. It operates to 30kHz even with a magnetic mount – a feat almost unheard of in the condition monitoring industry – and captures high frequency gear mesh faults that are often missed during routine route-based measurements.
Due to the sensor’s high frequency range, it is ideal for measurements on high-speed compressors, gear boxes and turbomachinery, to provide early detection of impending problems. When analysing the condition of an integral gear compressor, for example, a technician needs to be able to examine gear mesh frequency and its sidebands. The harmonics of the gear mesh and natural frequency of the gears play a significant role in diagnosing potential machinery faults. With a magnetically mounted 621B40 supplying a response to more than 30kHz, a vibration analyst can obtain precise measurements of these revealing high frequency phenomena.
For even higher frequency measurements, PCB Piezotronics can supply its 352A60 sensor that features an upper frequency range of 60kHz at ±3dB and is designed to work with a stud mount adhesive base (supplied).
Principal performance specifications of the 621B40 sensor include sensitivity of 10mV/g, measurement range of ±500g and frequency range from 1.6Hz to 30kHz (±3dB). Shock resistant to 10000g peak, the 621B40 operates over the temperature range -54 to +121°C.
