Hydraulic motor Its application and the solutions to common faults are similar to those of hydraulic pumps of the same type. However, because the working standard of hydraulic motor is different from that of hydraulic pump, it also has its unique application precautions.
1. When the inertia force of the driven part is large (inertia torque is large or speed ratio is high), if the braking or regular running is achieved within a specified short period of time, a valve (buffer valve) should be set in the oil return passage to avoid the destruction of safety accidents caused by large hydraulic machine impact.
2、 When applying the quantitative analysis motor, if the starting and parking stability is expected, the necessary CB Hagelung hydraulic motor The control loop shall be designed by operating with working pressure difference or flow monitoring.
3. When the hydraulic motor is used as the driving force of lifting or moving equipment, it is necessary to set the speed limit valve to prevent the lifting object from falling or moving quickly
Vehicles and other lifting mechanisms will overspeed when going downhill, resulting in serious accidents.
4. Because the hydraulic motor will always leak, the inlet and outlet of the hydraulic motor will be closed to carry out braking, and it will still move slowly. When braking for a long time is required, the brake shall be repeatedly set to avoid rotation.
5. When it is necessary to start the application with full load, pay attention to the starting torque of the hydraulic motor. Since the starting torque of the hydraulic motor is shorter than the rated torque, if ignored, the organization may not be able to operate during operation.
6. Because the back pressure of the hydraulic motor is higher than the atmospheric pressure, the motor oil drain pipes need to be independently led back to the car oil tank, and cannot be connected with the hydraulic motor oil return pipe.
