Guoliuqing wrecker hydraulic motor maintenance

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

        2. Generally, there should be sufficient back pressure for the oil return port of the low speed motor. This should be the case for the inner curve motor. Otherwise, the roller may break off the surface and cause impact. It will generate noise, reduce the life and crush the roller. The entire 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 will cause pressure spikes. The pressure relief valve cannot react so fast to protect the 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 fuel level 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 wrecker 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 action. Small changes in sound, vibration, and heat all mean problems with the motor. Making a click sound means there is a gap, and a bad bearing or bushing may give an unusual hum and vibration. When the motor feels hot, then this significant heat rise indicates a fault. A reliable indication of poor motor performance can be seen on the machine. If the machine works well in the morning, it loses momentum on this day. This means that the performance of the motor is deteriorating. The 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.
