2 Oil-water cooler for splash lubrication /OWC2.1 Structure/function2.1.1 Structure

An oil-water cooling system can be used if the thermal rating of the naturally cooled gearunit or cooling using a fan on the input shaft is not sufficient. The prerequisite for usingan oil-water cooling system is that appropriate cooling water is available on site.

SEW-EURODRIVE uses 2 different types of heat exchangers:

• For gear unit sizes X140 – X170, a plate heat exchanger is used for oil supply sys-tems OWC 005/015/025.

INFORMATION• Consult SEW-EURODRIVE if you use chemically aggressive cooling media, such

as brackish water or salt water.• The following information applies to gear units with splash lubrication. The cooling

system with motor pump only cools the gear unit oil.• Also refer to the operating instructions of the cooling system manufacturer.

2.3.3 Cooling media

Permitted cooling media

• Water, water/glycol cooling liquids, HFC refrigerants

• Cooling water temperature and volume flow of oil and cooling water according to theorder documents.

Dirt The quantity of suspended solids (ball-shaped, particle size < 0.6 mm) should be lessthan 10 mg/l. Threadlike contaminants increase the risk of pressure loss.

Corrosion Limit values: free chlorine < 0.5 ppm, chlorine ions < 200 ppm, sulfate < 100 ppm,ammonia < 10 ppm, free CO < 10 ppm, pH 7-10.

The following ions do not have a corrosive effect under normal conditions: phosphate,nitrate, nitrite, iron, manganese, sodium, potassium.

INFORMATION• Note that the service life, the efficiency, and the maintenance intervals of the heat

exchanger depend to a great degree on the quality and contents of the coolingmedium.

• Special procedures are required when sea water or brackish water is used. ConsultSEW-EURODRIVE.

INFORMATIONObserve the additional manufacturer's documentation.


2Notes on checking the oil levelOil-water cooler for splash lubrication /OWC

2.3.4 Installation and connection information

The cooling system is mounted directly on the gear unit as standard.

Optionally, the cooling system can be delivered as a complete unit on a mounting framefor separate installation but without electrical connections and piping. Provide for a low-vibration installation location max. 1 meter from the gear unit. Install the cooling systemat the same level as the gear unit or lower. If this is not possible, contact SEW-EURO-DRIVE.

Adhere to the following basic conditions when connecting the cooling system to the gearunit:

• Do not reduce the specified cable cross sections.

• It is important that you choose the correct wall thickness and material when selectingpipes, hoses and screw fittings. Preferably use composite material seals for screwfittings.

SEW-EURODRIVE recommends the following cable cross sections for connecting thecooling system to the gear unit and the cooling circuit:

2.4 Notes on checking the oil levelUsing an oil supply system might influence the oil level (page 16). The fill quantitiesspecified on the nameplate are guide values and refer only to the gear unit. The markon the oil sight glass, oil level glass or oil dipstick is the decisive indicator for the correctoil level.

3.3 Electrical connection

DANGER

Electrical voltage Electrocution hazard.

Before opening the cover or working on electrical components, disconnect the device from power supply. Make sure that the equipment cannot be reconnected to mains unintentionally.

Installation and maintenance must be carried out by trained staff only. Regard correct mains supply.

CAUTION

Electrical voltage

Wrong mains voltage may damage the device. Installation of the device shall be performed by trained staff only. Regard the voltage given on the type plate. Make sure that the cables have sufficient strain relief.

Fusing Fusing has to be done due to local standards

Polarity Take care of the directional rotation of the motor. The rotation direction is indicated on the motor housing “M” and an arrow.

The rotational direction is changed by exchanging the connection two phases.

For calculating the correct values of fuses and cross-section of connection wires, refer to local rules and standards. The motor and, if equipped, starting devices must be connected to protective earth.

Lead fuses protect the cables in case of a short cut, but are not sufficient to protect the motor coils from burning due to overload. Therefore, install an adequate motor circuit breaker with high precision range of adjustment for thermal protection to protect the motor against overload and operation with two phases.

Adjust the motor circuit breaker according to the nominal value given on the type plate of the motor. Operation out of the limits for mains voltage and frequency range is prohibited.


16 BX370001, 03/2011 Art. Nr. 3700001

3.4 Hydraulic connections The connecting line between pump and system should be free of tension and vibration. We recommend using flexible hoses which of course must be able to stand the negative pressure in the suction line. Use wire reinforced hoses for example.

Contaminated liquids reduce the life time of the pumps elements. Therefore we suggest filtering with a minimum of ß25 ≥ 75.

Make sure that the diameter of the suction line is not smaller than given in the technical data.

The pump produces a maximum suction pressure of 0.4 bar (5.8 psi). At first start-up, problems may occur with hydraulic systems with long suction lines because the suction line contains too much air. In this case, we recommend filling the suction line with oil and using a suction valve without spring.

Why Coolers?

Why Bühler?

Description

There are basically two main concepts in the development offluid power systems. One is to design systems minus acooler and if the operational conditions show in practice thatthe system needs a cooler to install it later.This however requires compromises that usually result infinancial overspend.The other concept recognises that a system originallydesigned with an integrated cooler can be built morecompact, needs less installation space and runs morereliable due to the stabilized temperature of the fluid.

Since water is becoming a precious resource, significantlyreduced water consumption is favoured by the systemdesigners. After over 25 years experience in design andsales of traditional tube and shell heat exchangers Bühlerrecognised that a new concept was required to meet theincreasing demand for water conservation.The plate heat exchanger fulfills this requirement particularlyfor the fluid power market.In cooperation with a well-known international manu-facturer of plate heat exchangers, Bühler has developed acomprehensive range of braced plate coolers specificallyfor fluid power applications. Bühler has been offering thisnew concept of oil / water coolers now for over five years withincreasing recognition and success.

If our comprehensive standard range of products does nothave an answer for your application we will be pleased to findspecial solutions for your application.

The data contained in this leaflet is sufficient to determinethe right cooler for your application. However, we can offeryou a software which makes this sizing easier.

The BWT oil / water coolers consist of a number of profiledstainless steel plates. The direction of the profile is reversedon every other plate so that the ridges on adjacent platesintersect with another forming a network of contact points.The subsequent brazing process creates a very compactand pressure resistant package, which virtually utilizes allmaterial for heat transfer.Compared with traditional systems the complex geometry ofthe BWT plate cooler provides a highly turbulent flow withvery equal distribution resulting in an outstanding heattransfer efficiency. Even at lower velocities a turbulent flow isinsured which is constantly changing direction due to theprofile and thus disturbing the boundary layer.BWT plate coolers are much less prone to fouling thancoolers of traditional design thanks to the smooth surfacequality of the cooler plates and the turbulent flow. Experienceshows that fouling is not a problem in plate coolers providingthe application parameters have been indicated correctly.DE 34 0001

2.1 General indication of risk Installation of the device shall be performed by trained staff only, familiar with the safety requirements and risks.

Adhere to all relevant safety regulations and technical indications for the specific installation place. Prevent failures and protect persons against injuries and the device against damage.

The person responsible for the system must secure that:

- safety and operation instructions are accessible and followed, - local accident prevention regulations and standards are obeyed, - performance data and installation specifications are regarded, - safety devices are installed and recommended maintenance is performed, - national regulations for disposal of electrical equipment are obeyed.

Maintenance and repair

- Repairs on the device must be carried out by Bühler authorized persons only. - Only perform modifications, maintenance or mounting described in this manual. During maintenance regard all safety regulations and internal operation instructions.


12 BX340001, 08/2013 Art. Nr. 34001

3 Installation Plate heat exchangers should be installed in such a way that there is sufficient free space around each unit to carry out maintenance work, etc.

The plate heat exchangers can be installed in any position. However, when they are used as evaporators or condensers they should be installed in a vertical position because performance may decline when they are installed in another position.

4 Connection of pipes

!

NOTE

Piping must always be installed in such a way that no movement in the piping and no unadmissible forces are transferred to the plate heat exchanger!

WARNING

Voltage flashovers

Electrocution hazard

Do not earth the heat exchanger when carrying out welding work!

The designation of the connections of the plate heat exchanger are marked on the name plate. The connections for the primary and secondary side are described in the offer.

The plate heat exchangers are connected in parallel in counterflow. The cirquits to be connected should be rinsed before carrying out the connection.

Piping to and from plate heat exchangers should be provided with shut-off valves. In addition, vent valves should be provided in the upper connections at the highest point, and drain valves in the lower connections.

When connecting the plate heat exchanger it must be ensured that the gaskets of the connection bolts are clean.


BX340001, 08/2013 Art. Nr. 34001 13

5 Commissioning / Operation Before operation it must be checked that the operating data does not exceed the data indicated on the marker's nameplate. Furthermore all bolted connections must be checked for tightness.

CAUTION

Hazard due to high pressure

Do not exceed the nominal pressure.

Install safety valves (pressure relief valves) to pumps that generate higher pressures.

5.1 Pumps The pumps feeding the plate heat exchanger must be equipped with control valves. Pumps which generate pressures higher than those specified for the unit must be equipped with safety valves. The pumps must not suction air to preclude operating faults through water hammers.

5.2 Start – up

!

NOTE

Pressure surges should be avoided.

To avoid hydraulic shocks the pumps should be started up against closed valves. The valves in the supply and the return lines should be opened slowly, if possible simultaneously, until the operating temperature is reached.

5.3 Venting / Ventilation During the filling process the unit must be vented through the vent valves installed in the piping. Plate heat exchangers which are not vented to a sufficient degree do not achieve full performance because the heating surface is covered by air. Furthermore the corrosion risk increases when air remains in the unit.

5.4 Shut - down The two sides should be shut - down simultaneously and slowly. If this not possible the hot side should be shut down first.

If the cooler is shut down for a long time it should be drained completely and cleaned. The should be specially when there is a danger of frost and when aggressive media are involved.


14 BX340001, 08/2013 Art. Nr. 34001

6 Fouling / cleaning of heat exchangers water side If cooling media are used which are possibly contaminated, such as surface water, cooling circuit water (open circuit), heating installation water (specially in the case of old installations) etc., filter having a mesh width of max. 0.6 mm should be provided in the feed line. Furthermore, if such media are used, the unit should be operated with the largest possible mass flow. If the mass flow is too small (partial load) the turbulence in plate heat exchanger may decrease and susceptibility o fouling may increase.

If formation of deposits due to the water quality (e.g. high degrees of hardness or heavy contamination) is expected, the unit should be cleaned at regular intervals. It is possible to clean the unit by rinsing. A weak acid, e.g. 5% phosphoric acid, or the cleaning agents offered by relevant suppliers to clean copper and stainless steel should be used to rinse the unit.

CAUTION

Acid and corrosive substances

Phosphoric acid can harm skin and eyes.

Wear protection gloves and face protection

If possible, the rinsing process should be carried out in the opposite direction to that of the operating flow and, where necessary, back rinsing connection should be provided in the piping. The unit must then be sufficiently rinsed using clear water to remove all residues of cleaning liquid before the system is put into operating again.
