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.
