Before the hydraulic motor is actually delivered for use, it generally needs to be cleaned. The goal of cleaning is to clean the residual pollutants, metal material scraps, chemical fibers and chemicals in the motor The iron core, etc., will cause a series of common faults even if the motor is not completely damaged during the gradual two-hour operation. Therefore, the swing hydraulic motor needs to clean the motor oil passage according to the following process:

1. Rinse the car oil tank with a dry cleaning solution, and then remove the organic solvent sediment with filtered gas.

2. Clean all pipelines of the motor. In some cases, prepreg the pipelines and interfaces.

3. Install oil filter on the pipeline to maintain the oil pipeline and pressure pipeline provided by the valve.

4. Use a cleaning plate on the collector to replace high-precision valves, such as electro-hydraulic servo valves.

5. Check whether the specifications of all pipelines are suitable and whether the connections are appropriate. To reduce the pressure energy loss when applying hydraulic motor, the hydraulic motor shall be driven gradually from the inside to reduce the output power loss together with reducing the internal pressure loss of the system software. To solve this problem, the pressure loss of the internal gate of the components can be improved. The five star hydraulic motor uses an integrated control loop and a forging runner. At the same time, the loss of throttle valve of the operating system must be reduced or eliminated, and the total overflow flow that is not necessary for safety must be reduced as far as possible to prevent the use of throttle valve system software to control the total flow and pressure.

In the application of materials, materials produced by negative pressure technology and new rubber seals can be used, so that friction loss can be reasonably reduced. The maintenance during operation is necessary. The hydraulic motor should be maintained immediately to avoid the damage to the motor life and stability caused by environmental pollution. New pollution monitoring methods should be developed to automatically measure environmental pollution. Immediate adjustment should be made to prevent losses caused by untimely disposal. In order to reduce the pressure energy loss of the hydraulic motor, the manufacturer and the customer must work together to avoid the pressure energy loss to a large extent.
