How to clean the hydraulic press?

Hydraulic presses are contaminated in manufacturing, testing, use and storage. And cleaning to eliminate pollution, so that hydraulic oil, hydraulic components and pipes to maintain an important means of cleaning.
Production, the hydraulic press cleaning is usually the main system cleaning and system-wide cleaning. System-wide cleaning refers to the entire hydraulic circuit of the hydraulic device to be cleaned. The system should be restored to the actual operating state before cleaning. Cleaning media available hydraulic oil; cleaning time is generally 2-4h, special circumstances do not exceed 10h; cleaning effect to the filter without impurities on the filter as the standard.
Cleaning should pay attention to the following points;
① general hydraulic press cleaning, the use of more use of 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 During the cleaning process, the hydraulic pump is running and the cleaning medium is heated at the same time. When the temperature of the cleaning oil is 50-80 ° 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 hit, in order to facilitate the removal of pipe attachments.
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, 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 the end of the hydraulic pump will continue to run until the temperature back to normal.
⑧ hydraulic cleaning machine to clean the cleaning oil inside the circuit.
