The main specification of the hydraulic motor

1. Working pressure and rated pressure of the hydraulic motor
Working pressure: the actual pressure of the input motor oil, which depends on the load of the motor. The difference between the inlet pressure and the outlet pressure of the motor is called the differential pressure of the motor. Rated pressure: the pressure that enables the motor to work continuously and normally according to the test standard.

2. Displacement and flow of the hydraulic motor
Displacement: the volume of liquid input required for each revolution of the hydraulic motor without considering leakage. VM (m3 / RAD) flow: the flow without leakage is called theoretical flow qmt, and the leakage flow is considered as actual flow QM.

3. Volumetric efficiency and speed of the hydraulic motor
Volumetric efficiency η MV: ratio of actual input flow to theoretical input flow.

4. Torque and mechanical efficiency

Without considering the loss of the motor, its output power is equal to the input power. Actual torque T: torque loss due to actual mechanical loss of motor Δ T. Make it smaller than the theoretical torque TT, that is, the mechanical efficiency of the motor η Mm: equal to the ratio of the actual output torque of the motor to the theoretical output torque
