Vane pump, a vane pump housing (stator rings) contact with the rotor groove, the suction of the liquid from the inlet side pressure to the discharge side of the oil pump.In addition to be anti-dry transfer and overload, anti-air and suction vacuum suction through the large, we must also pay attention to: 1. Steering pump change, it also changes the direction of the suction and discharge provisions of the steering vane pump has allowed reversed. Because tilt rotor blade slot blade chamfer, bottom leaves and drain the oil chamber through the throttle slot on the oil pan and suction, discharge port is designed in accordance with established steering. Reversible vane pump must be specifically designed. 2. Vane pump oil pan and the stator assembly positioned correctly with locating pins, blades, rotor, oil pan are not installed backwards, the inner surface of the stator suction area some of the most easy to wear, it can be reversed if necessary to install, so the original suction zone change to continue to use the discharge area. 3. Disassembly attention to the work surface is clean, work should be well filtered oil. 4 leaves too much leakage will increase in leaf slot gap is too small can not freely retractable blade will cause malfunction. 5. Axial clearance vane pump a great influence on v. 1) small pump -0.015 0.03mm 2) Medium pump -0.02 0.045mm 6. Oil temperature and viscosity generally should not exceed 55 , viscosity requirements between 17 37mm2 s. The viscosity of the oil-absorbing too much difficulty; viscosity is too small leak worse.
