VDR13 Design Series Variable Volume Vane Pump

Transcription

1 VR SRS VARA VU VA PUP VR13 esign Series Variable Volume Vane Pump to 4l/min 6Pa The new design number 13 was created by modifying some of the components of old design numbers 11 and 1, and the new design installation compatible with the old design. eatures qnergy efficient, economical operation. wuilt-in high-precision temperature compensation mechanism. ethe ring is displaced by a spring, and a rise in pressure automatically moves it to the center to make the discharge rate zero. rrelief valve and unloading valve can be eliminated from the circuit. tt was possible to reduce the size of the unit because there was no increase of proportional input to pressure which prevented increases in the temperature of the fluid. yew design for lower noise and improved durability.

See page - for more information. 3. The change from VR-1 Series design number 11 to design number 1 represents a change in the shaft key width from 3.mm to 4.76mm. This means that when using a 3.mm key coupling, you need to use a stepped key (V31-3) or add a new key groove at There is no change in the mounting method with the change from the VR-1 size design number 1 and VR- design number 11 to design number 13. in. ax. -1

Use hydraulic operating fluid that provides kinematic viscosity during operation in the range of to 1mm /s..the operating temperature range is 1 to 6. When the oil temperature at startup is 1 or less, perform a warm-up operation at low pressure and low speed until the oil temperature reaches 1. Use the pump in an area where the temperature is within the range of to 6. Suction pressure is -.3 to +.3Pa (-.3 to +.3f/cm ), and the suction port flow rate should be to greater than m/sec Rotation angle θ (clockwise) -16

3 1Avoid pulley, gear, and other drive systems that impart a radial or thrust load on the end of the pump shaft. ount the pump so its pump shaft is oriented horizontally. Provide a suction strainer with a filtering grade of about 1μm (1 mesh). or the return line to the tank, use a μm line filter. 3anage hydraulic operating fluid so contamination is maintained at class AS1 or lower. Take care to avoid contamination with water and other foreign matter, and watch out for discoloration. Whitish fluid indicates that air has contaminated the fluid, and brownish fluid indicates the fluid is dirty. 4At startup, repeat the inching operation (start-stop) to prime the pump and bleed air from the pump and pipes. (This pump has no fluid supply port.) quip an air bleed valve in circuits where it is difficult to bleed air before startup. See page -13 for more information. 6When centering the pump shaft, eccentricity with the motor shaft should be no greater than.mm. Use a pump mounting base of sufficient rigidity. The angle error should be no greater than 1. nverter rive Precautions zset the revolution speed within the range of the pump specification revolution speed. xhanging the revolution speed may also affect the pump performance curves. efore using the inverter, check if the pressure and motor load factor are within the range of use. nstallation imension rawings VR-1A-*-13 (oot ounting) low rate.1 h 3.9 Sub-plate Rc Y (pposite side) R Rc 1/4 (pposite side) ote: Sub-plate is not provided. ust be provided separately if needed.
