Precautions For Cleaning After Use At The Hydraulic Station
When the hydraulic station is cleaned, hydraulic oil or test oil for working use is often used.
1, can not use kerosene, gasoline, alcohol, steam or other liquids to prevent corrosion of hydraulic components, piping, fuel tanks and seals;
2. During the cleaning process, non-metallic hammer rods can be used to strike the tubing, and can be tapped continuously or intermittently in order to facilitate the removal of attachments in the pipeline;
3. During the cleaning process, the operation of the hydraulic pump and the heating of the cleaning medium are performed simultaneously. When the temperature of the cleaning oil is (50-80) °C, the rubber slag in the system is easily removed;
4. In the circuit of cleaning oil circuit, filter or filter should be installed. At the beginning of cleaning, due to more impurities, an 80 mesh filter can be used, and after the cleaning, a filter with more than 150 meshes can be used.
5, intermittent operation of the hydraulic pump is conducive to improving the cleaning effect, the intermittent time is generally (10-30) min;
6, in order to prevent external moisture caused by corrosion, the end of cleaning, the hydraulic pump should continue to run until the temperature returned to normal;
7, cleaning time is generally (48-60) hours, according to the system's complexity, filtration accuracy requirements and pollution levels and other factors;
8. After the hydraulic station is cleaned, the cleaning oil in the circuit should be eliminated.
