Hydraulic system will suffer from environmental pollution in production, experiment, application and storage. Cleaning is the key way to eliminate environmental pollution and keep gear oil, hydraulic system and pipeline clean. In production, the cleaning of hydraulic system generally includes main system software cleaning and whole system software cleaning. The whole system software cleaning refers to the cleaning of all circuits of the hydraulic control valve. Before cleaning Cycloidal hydraulic motor sample Restore the system to the specific operation condition.

Gear oil can be used as cleaning material, MSE internal curve hydraulic motor The cleaning time is generally 2-4 hours, and it does not exceed 10 hours under special circumstances. The actual cleaning effect is subject to the crystallization on the loop filter screen.

Common problems during cleaning:

1. In general, gear oil or commissioning oil used in work is mostly used for cleaning hydraulic system. Gasoline, automobile gasoline, ethanol, steam or other liquids shall not be eroded by hydraulic systems, pipeline oil tanks and hydraulic seals.

2. During the whole cleaning process, the operation of hydraulic oil pump and the heating of cleaning materials shall be carried out separately. When the temperature of cleaning hydraulic oil is (50-80) ℃, the vulcanized rubber residue in the system software is very easy to remove;

3. During the whole cleaning process, the oil pipeline can be knocked with a non-metallic hammer, either continuously or discontinuously, to facilitate the removal of accessories in the pipeline;

4. Intermittent operation of hydraulic oil pump is conducive to improving the actual effect of cleaning, and the interval time is generally (10-30) minutes;

5. Filter device or filter screen shall be installed on the circuit for cleaning the oil passage. At the beginning of cleaning, because there are many residues, 80 mesh filter screen can be selected, and the filter screen above 150 mesh can be changed in the middle and later stages of cleaning;

6. The cleaning time is generally (48-60) hours, which should be decided according to the complexity of the system software, filter precision regulations, environmental pollution level and other factors;

7. In order to better avoid rusting caused by external moisture, after cleaning, the hydraulic oil pump should continue to run until the temperature recovers to the last;

8. Clean the cleaning oil in the circuit after cleaning.
