Vane pump common troubleshooting - pump temperature is too high 1. Pressure is too high, too fast 2. Oil viscosity is too large 3. Tank cooling conditions are poor 4. Serious friction with the oil pan and rotor 5. Tank volume is too small 6. Blade And the inner surface of the stator wear serious 1. Adjust the pressure valve to reduce the rotation speed 2. Choose the appropriate viscosity of the oil 3. Increase the tank volume or increase the cooling device 4. Repair or replacement with oil pan or rotor 5. Increase the fuel tank to expand the heat Area 6. Grind or replace the leaves, the stator, take measures to reduce wear and tear More keyword search: vane pump
