Cleaning should pay attention to the following points;
① general hydraulic press cleaning, the use of working with the hydraulic oil or test oil. However, kerosene, gasoline, alcohol, steam or other liquids can not be used to prevent corrosion of hydraulic components, piping, tanks and seals.
② cleaning process, the hydraulic pump operation and cleaning media heating at the same time. When the temperature of the cleaning oil is 50 to 80 ° C, the rubber slag in the hydraulic press is easily removed.
③ cleaning process, can be used non-metallic hammer rods hit the tubing, can be continuously tapping, in order to clear the pipe within the attachment.
④ hydraulic pump clearance operation is conducive to improve the cleaning effect, intermittent time is generally 10-30min
⑤ in the cleaning circuit on the oil return road, should be installed filter or filter. At the beginning of cleaning, due to more impurities, can be used 80 mesh filter; cleaning later switch to more than 150 mesh filter.
⑥ cleaning time is generally 48-60h, which depends on the complexity of the system, filtration accuracy requirements and pollution levels and other factors.
⑦ hydraulic machine in order to prevent external moisture caused by corrosion, cleaning at the end, the hydraulic pump will continue to run until the temperature back to normal.
⑧ hydraulic machine after cleaning the cleaning oil to remove the clean.
