Precautions during cleaning of hydraulic pump station:

1. Generally, when cleaning the hydraulic pump station, the working hydraulic oil or test oil is mostly used. Kerosene, gasoline, alcohol, steam or other liquids shall not be used to avoid corrosion of hydraulic components, pipelines, oil tanks and seals;

2. During the cleaning process, the operation of the hydraulic pump and the heating of the cleaning medium are carried out at the same time. When the temperature of the cleaning oil is (50-80) ℃, the rubber slag in the system is easy to remove;

3. During the cleaning process, non-metallic hammers and rods can be used to knock the oil pipe, which can be knocked continuously or discontinuously, so as to facilitate the cleaning of attachments in the pipeline;

4. The intermittent operation of the hydraulic pump is conducive to the cleaning effect, and the intermittent time is generally (10-30) min;

5. A filter or strainer shall be installed on the circuit of the cleaning oil circuit. At the beginning of cleaning, due to many impurities, 80 mesh filter screen can be used, and at the later stage of cleaning, filter screen with more than 150 mesh can be used;

6. The cleaning time is generally (48-60) hours, which should be determined according to the complexity of the system, filtration accuracy requirements, pollution degree and other factors;

7. In order to prevent corrosion caused by external moisture, the hydraulic pump should continue to operate until the temperature returns to normal after cleaning;

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