What is the reason for unstable speed or insufficient output torque of the axial piston motor?

2025-04-28

Unstable speed may be caused by many factors: First, the oil supply pressure is insufficient or unstable. It is necessary to check the working status of the axial piston pump and the system pressure setting. Secondly, the internal leakage of the motor is too large, especially the wear between the valve plate and the cylinder body will lead to a decrease in volumetric efficiency. The matching surface should be checked and the worn parts should be repaired or replaced. Improper adjustment of the variable mechanism can also cause unstable output, and the variable mechanism needs to be recalibrated. Hydraulic oil viscosity is too low or the oil temperature is too high, which will increase internal leakage. The appropriate viscosity oil should be selected and the cooling system should be checked. Excessive external load fluctuations will also affect the speed stability. It is necessary to check whether there are any abnormalities in the load connection parts.
