Characteristics of the unit

Characteristics of the unit

The service-friendly VarnishElimination Units VEU are used to condition mineral oils. They are particularly effective at removing oil aging products (varnish) from mineral oils. Varnish takes the form of oil-insoluble oil degradation products which settle in the tank, the valves or the bearings. These can be filterable gels or solid paint-type deposits. The VEU-F series of units is used in the bypass flow. The varnish is removed by reducing the oil solubility of varnish and then filtering it out. Fields of application or the VEU-F include:

• Removal of solid or gel-like oil degradation products in lubrication and hydraulic systems, e.g. in:

o Presses o Machine tools o Systems with H1 food-grade oils o Turbine lubrication

Using the VEU-F can offer you the following advantages:

• Increased operating reliability of the system as a result of fewer deposits in hydraulic valves

• Increase in the oil service life

Setting up / Installing VEU-F


Observe the following points when setting up the unit: 1. The unit must be set up on an even, level surface. 2. Make sure that there is sufficient space above the filter housing to

replace the filter elements. 3. Make sure that there is sufficient space above the side cooler. For more

details, see the Installation and Maintenance Instructions for the side cooler, which are included in the Technical Documentation for the unit.

4. Observe the maximum permissible ambient temperature and constant supply of cooling air for units which have a motor-pump assembly to avoid overheating.

5. In the case of installation below the fluid level, install shut-off valves in the feed and return lines.

6. Connect the suction and pressure ports as described on pages 27 to 28.

7. Connect all the unit's electrical connections. See page 29 for details 8. When starting up for the first time, follow the steps below: - Fill the side cooler with a water/glycol mixture; for more details, see

page 28. - Insert the filter elements in the filter housing.

See page 34 for details.

VEU-F-60/1-x-C… en(us) / 52



Notes on pipes/hosing Make sure that no vibrations or stress/loading from other machinery and equipment are carried over to filter housing. If necessary, use expansion joints. The pressure loss in a hydraulic line depends upon:

• Flow rate

• kinematic viscosity

• Pipe dimensions

• fluid density The pressure loss can be estimated for hydraulic oils as follows:

Δp ≈ 6.8 * L / d4 * Q * V * D Δp = Pressure differential in [bar]

L = Pipe length [m]

d = Internal pipe diameter [mm]

Q = Flow rate [l/min]

V = Kinematic viscosity [mm²/s]

D = Density [kg/dm³] Mineral oil based hydraulic fluid has a density of ≈ 0.9 kg/dm³.

This applies to straight pipelines and hydraulic oils. Additional threaded connections and pipe bends increase the pressure differential. Additional threaded connections and pipe bends increase the pressure differential. Keep the height difference between the pump and the oil level in the tank as low as possible. Constrictions in the connections and lines should be avoided. This could compromise suction output and cause cavitation. Take note that the nominal size of the connected hoses/piping must be at least as large as the inlet port sizes. Make sure that no vibrations or stress/loading from other machinery and equipment are carried over to filtration unit. Make sure that no vibrations or stress/loading from other machinery and equipment are carried over to filtration unit. Use hoses or expansion joints if necessary.

VEU-F-60/1-x-C… en(us) / 52



Connecting the suction port - INLET

For the suction port connection, use a flexible hose that is resistant to negative pressure. Avoid constrictions in the connecting lines, as they compromise suction performance and increase the risk of cavitation. In case of coarse contamination (> 100 µm) such as weld splatter, an appropriate suction strainer must be installed in the suction line in order to protect the pump. If a unit without a motor-pump assembly is used, it is important to ensure that no pressure pulsation is transmitted to the filter housing.

NOTICE

Overpressure at the suction port connection

The unit will be damaged

► The maximum pressure on the suction port IN must not be more than -0.4 to 2.0 bar.

Connecting the pressure port - OUTLET Make sure that the nominal width of the pressure line corresponds to the connector thread of the filter housing. Install the return line below the oil level to prevent air from entering the fluid in the tank.

If the clogging indicator pressure displayed for the a clean filter element is > 1 bar, use a differential pressure clogging indicator.

Preparing the RFCS side cooler Remove the metal air filter from the side cooler and fill the tank with the water/glycol coolant (min. 20% … max. 40%) up to the "Max." mark using the tank filling nozzles on the side cooler. Insert the metal air filter in the side cooler and check that the side cooler is switched on at the main switch (13.1). For more details, see the Installation and Maintenance Instructions for the side cooler, which are included in the Technical Documentation for the unit.

VEU-F-60/1-x-C… en(us) / 52



Electrical connection of the unit Check the voltage and frequency specifications on the motor name plate against the existing network specifications. Plug the male connector into a suitable, grounded power outlet.

Checking direction of rotation Check the direction of rotation of the motor by switching it on briefly (jog mode). The unit requires a clockwise rotating field at the connecting socket.

NOTICE

Incorrect phase sequence / rotation direction of the motor

The pumps will be destroyed.

► In jog mode, check the direction of rotation of the motors. ► A rotation direction arrow on the fan cover of the motor identifies the

correct direction of rotation.

If rotation is in the opposite direction, change the phases in the terminal box or rotate the phases in the connection plug using the phase inverter in the connection plug.
