1) The speed and pressure cannot exceed the specified value.

2) Generally, there should be sufficient back pressure for the return port of the low-speed hydraulic motor. This should be the case for the internal curve hydraulic motor. Otherwise, the roller may break off the surface and cause impact, which will generate noise, reduce the life, and crush the roller. , the entire hydraulic motor is damaged. Generally, the back pressure value is about 0.3 to 1.0 MPa. The higher the rotation speed, the higher the back pressure should be.

3) Avoid sudden start or stop when the system is under load. Sudden start or stop of the brake when the system is under load will cause pressure spikes. It is impossible for the pressure relief valve to react so quickly to protect the hydraulic motor from damage.

4) Use lubricating oil with good safety performance, the number of lubricating oil should be suitable for the specific system.

5) Always check the oil volume of the fuel tank. This is a simple but important preventive measure. If the leak is not found or not repaired. Then the system will quickly lose enough hydraulic oil to create a vortex at the pump's population. Make the air breathable. Thereby causing damage.

6) Keep the hydraulic oil as clean as possible. Behind the failure of most hydraulic vehicles and hydraulic hydraulic motors, there is a drop in the quality of hydraulic oil. Most of the failures are caused by solid particles (particles), contaminants and overheating, but water and air are important factors.

7) Capture the fault signal and take timely measures. Small changes in sound, vibration, and heat can all cause problems with hydraulic motors. Making a click sound means there is a gap, and a bad bearing or bushing may give an unusual hum and vibration. When the hydraulic motor feels hot, then this significant heat rise indicates a fault. A reliable indication of poor hydraulic motor performance can be seen on the machine. If the machine works well in the morning, it loses momentum on this day. This shows that the performance of the hydraulic motor is deteriorating. The hydraulic motor has been worn out, there is an internal leak, and the leak increases with increasing temperature. External leakage may also occur due to internal leakage that can deform the gasket and the collar.
