If these two conditions occur in the vane pump, it will cause unnecessary energy waste and damage to the hydraulic system. Therefore, when a similar situation occurs, we should deal with it in time to avoid greater damage to the hydraulic system.
Elimination of external leakage of vane pump:
1. The seal is aging, replace the seal
2. Loose connection of inlet and outlet ports
2. Tighten pipe joints or flange screws
3. The sealing surface bumps or the casing of the pump has trachoma
3. Grind the sealing surface or replace the shell
Analysis of abnormal heat failure of vane pump:
1. The oil temperature is too high 2. The oil temperature is too high and the internal leakage is too large
3. Working pressure is too high
4. The oil return port is directly connected to the pump population
Elimination of abnormal heat of vane pump:
1. Improve the heat dissipation condition of the fuel tank or use a... أقل
