External gear oil pump is applied and its oil

supply performance is better than current rotor

pump. The efficiency of external gear pump is

high, that is, the efficiency of oil supply is

proportional to the speed, which may satisfy

large-load oil supply requirement. However, if

rotor pump speed increase, the oil pump

efficiency will increase at low speed, but it will

drop gradually when the speed reach mid-speed as

shown, which will cause lack of large-load oil

supply. Therefore, large load should be considered

when designing rotor pump, but it will consume

power during low loading.

Oil filter seating and pressure

limiting valve – Pressure limiting

valve is of plunger spring structure.
