Speed Problem Of Hydraulic Pump

The operating speed refers to the actual rotation speed of the pump (or motor) while working.
Rated speed refers to the highest speed that can operate normally for a long time under rated pressure. If the pump works beyond the rated speed, it will cause insufficient oil absorption, vibration and loud noise, and the parts will suffer cavitation damage and reduce the life.
The minimum stable speed refers to the minimum speed allowed for normal operation of the motor. At this speed, the motor does not creep.
