Rotary JointsSeries DQ

DQ series Rotary Joints are designed to accommodate a range of manufactu-ring / production applications. These specialized RotaryJoints have exceptionally proven tolerance in a numberof process environments including thermal oil toleran-ce up to 752°F (400°C), and rotational speed toleranceup to 2,000 RPM. Applied uses are commonly found ina variety of specialized industries and processes inclu-ding polymer, lamination and coating applications,paper and textile manufacturing processes includingnon-woven and textile calenders, industrial dryers androtary reaction vessels.
The US and internationally patented DQ system pre-vents the common failure consequence of carboniza-tion and cracking caused by hot thermal oil contactwith atmospheric oxygen. This chemical reactioncreates seal damage that causes the problems of im-proper hot oil and oil vapor discharge.
The specially designed failure avoidance features ofthe DQ system provide unique advantages:Atmospheric oxygen is isolated from the hot oil by abarrier fluid. A cooling unit is used with the DQ ,DQTand DQTX series to cool the barrier fluid using thesame (or compatible) heat transfer medium as in themain circuit. The DQ 5th Generation series requires no extra coolingunit. Instead it uses the existing lubricating oil circuitfrom the production machine. This eliminates the needof the cooling unit and allows considerably higherspeeds. The DQL version does not require a coolingunit because of its temperature limit of 482°F (250°C).
Advantages and Features
Much longer service life than other rotary joints.Longer uninterrupted run-times and no unscheduledmaintenance, since the rotary joint functions is efficiently monitored via the cooling unit.Significantly reduced risk of thermal oil leakage and escape of oil vapors. The primary seal is pressure balanced with a low torque rate A seal protector disk provides protectionagainst penetration by foreign particles. The exter-nally loaded mechanical seal provides added safety protection.The secondary seal is not subject to stress and is protected by the cooled barrier fluid.
The double wall rotor protects the bearings from extended high temperature exposure and prevents energy loss.The functions of the rotary joints are monitored continuously via the control elements on the cooling unit. In case of leakage, production can continue until the next scheduled shut-down due to tempo-rary containment of reusable filtered oil within the cooling unit.
Additional Technical Design Details:
Housing made from spheroidal graphite cast iron (up to 662°F / 350°C) or from high-temperature steel suitable for applications over 662°F (350°C).Unit sizes 1” to 1 1/2” with ball bearings; 2“ to 8“ with self-adjusting tapered roller bearings.DQ and DQT use conditioned oil (cooled and filtered)from the cooling oil loop. No need for re-lubrication.DQL uses high temperature grease for bearing lubrication.A sensor (provided by customer) for monitoring the bearings can be attached to the screw plug of the cooling oil circuit. Quick release K-flange and conical inner rings are used to connect the rotary joint to the roll journal.Radial and axial housing connections are equipped with ANSI standard flanges. DIN or other standards upon request.Barrier fluid connections with internal ISO 228 threads (British standard parallel pipe thread).Prevention of rotation by means of anti-rotation forks that can be mounted at 8 x 45° positions.Static support in the rotor for a rotating inner pipe prevents wear between inner pipe and bushing. For use of one cooling unit for several rotary joints, a flow distributor is recommended to distribute cooling oil evenly to several rotary joints.For further information and safety notations please refer to the Operating Instructions at www.maier-heidenheim.de or www.maieramerica.com.

KE + KEW Cooling Unit
Rotary Joints of series DQ are a part of an US and internationallypatented system that prevents the common failure consequence ofcarbonization and cracking caused by hot thermal oil contact withatmospheric oxygen. This chemical reaction would cause seal dama-ge which would result in improper hot oil and oil vapor leakage.To prevent this consequence, series DQ are especially designed tobe used in conjunction with a barrier fluid as cooling medium (useof the same heat transfer fluid as in the main circuit is recommen-ded). This combined utilization is a unique function that maximizesfailure avoidance throughout manufacturing processes.
The barrier fluid is conditioned (filtered and cooled) by the KE / KEW external cooling unit component. Type KE is equippedwith an air cooled heat exchanger. Type KEW has a water cooledheat exchanger. The cooling unit also serves as a constant monito-ring unit of the rotary joints’ functions. As a result, the cooling unit has the triple bonus features of monitoring the rotary jointswhile it simultaneously cools and filters the barrier fluid. The coo-ling unit also includes special monitoring elements which transmitsignals to a customer provided control unit (PLC). In case of anyleakage at the rotary joint it is possible to continue operation untilthe next scheduled shut-down, since the leaking oil is collected bythe cooling unit.
One cooling unit can simultaneously service multiple rotary joints. So that each rotary joint is equally sup-plied by the cooling unit, a flow distributor is recommended.
Hot thermal oil flows through the rotary joint and is sealed by the mechanical seal (primary seal P). If thehot thermal oil comes in contact with atmospheric oxygen in the sealing gap (P), chemicalreaction (carbonization) would be the result, leading to damages at seal (P) andbearing (L). Thus, a barrier fluid (second oil circuit) flows through thebearing and sealing area of the rotary joint in order to cool andlubricate these components. In addition, the primary seal (P) isisolated from atmospheric oxygen. The barrier fluid is seal-ed against atmosphere by a second seal (secondary seal S) and processed by cooling unit KE / KEW. These unique isolationmeasures (I) support the desiredeffect of the barrier fluid.
This solution improves thewear resistance and opera-tional reliability of therotary joints significantlycompared to conven-tional rotary joints.
Cooling Unit KE / KEW
Operating Principle
7
Integrated monitoring devices/alarms for temperature, flow rate,level min/max and filter condition will transmit an electric signalto the customer’s PLC, if an alarm situation is present. For properinstallation all necessary wiring, schematic and circuit diagramswill be supplied upon order.
Cooling Circuit for two or more Rotary Joints
Features of the Cooling Unit
For two or more rotary joints the cooling oil circuitis to be installed as shown in the diagram. A coo-ling oil distributor (KV) is recommended to com-pensate for differences in installation height, pipelength and cross sectional areas. The oil distributorensures an even oil supply (V1) to the rotary jointsand transmits an electric signal to the control unit,if the correct flow is not maintained.
Maximum pipe length is 82 ft (25 m). Please notethe minimum cross section of the pipes accordingto the diagram.
The maximum admissible head loss (pump pressureP0) in the system is 72.5 psi (5 bar). For furtherinformation please refer to the OperatingInstructions at www.maier-heidenheim.de orwww.maieramerica.com. Please call us for user ID and password.
