Cleaning method of hydraulic components during repair of servo hydraulic press

Because of the high accuracy of the servo hydraulic press, the mutual coordination gap of the moving parts is small. If impurities or metals are mixed in the device, it will cause the hydraulic original to wear or jam, and even form mechanical damage. Therefore, before the hydraulic element is installed, it is necessary to clean the hydraulic element.

When the hydraulic system through a period of long-term use and operation, because the hydraulic oil aging disintegration of the servo hydraulic press, there may be mixed with water, film and oil Hou and other magazine dirt, will affect the operation function of the system, so the hydraulic system should be cleaned regularly.

However, regardless of whether the hydraulic original is still a hydraulic system, it is necessary to pay attention to the following questions in cleaning.

1, clean the oil pipe, should avoid cotton yarn dirt impurities, mixed into the pipe, affecting the system function.

2. When cleaning the main body system, a temporary oil filter should be installed at the return pipe port of the main circuit to filter out the impurities and dirt in the main body system.

3, the cleaning of the main system, can not use fire oil, alcohol and other cleaning agents, to avoid corrosion of hydraulic components, usually choose the temperature of 38℃ viscosity of 20cst turbine oil as cleaning agent. If the oil temperature is increased to 50℃-80℃, its cleaning effect will be good.

4, after the end of cleaning, all departments should recover their original orientation, and clean the fuel tank everywhere, and add new hydraulic oil to the requirements of the equipment instruction manual.

5. After cleaning the original and hydraulic system, it is necessary to debug it item by item before it can be put into use.
