1. Pump steering change, then its suction and discharge direction also change the vane pump has a specified steering, do not allow the reverse. Because the rotor slots are tilted, chamfered leaves, the bottom of the leaves and drain chamber through, with the throttle on the oil pan and suction, exhaust port is designed according to the established steering. Reversible vane pumps must be specially designed.
2. Vane pump assembly with the oil pan and the stator with the positioning pin correct positioning, blade, rotor, with the oil pan shall not be installed against the inner surface of the stator suction part of the most vulnerable to wear, if necessary, can flip it installed so that the original inhalation zone change Continue to use for discharge area.
3. Disassembly pay attention to the work surface clean, oil should be well filtered at work.
4 blades in the leaf slots in the gap is too large will increase the leakage, too small then the leaves can not be free expansion, will lead to work disorders.
5. Vane pump axial gap ηv great influence.
1) Small pump -0.015 ~ 0.03mm
2) medium-sized pump -0.02 ~ 0.045mm
6. The temperature and viscosity of the oil generally should not exceed 55 ℃, viscosity requirements between 17 ~ 37mm2 / s. Viscosity is too large, oil absorption is difficult; viscosity is too small, the leak is serious.
Vane pump management points
In addition to anti-dry turn and overload, anti-inhalation of air and vacuum suction too large, but also:
