Because the precision of the original hydraulic press is higher, the fitting parts of the moving parts are smaller. If the device is mixed with impurities, perhaps metal, will lead to the original hydraulic wear or stuck, severe even when the formation of mechanical damage incidents. Therefore, it is necessary to clean the hydraulic components before the hydraulic components are installed.

When the hydraulic system through a long-term use and after the operation, because the hydraulic oil aging transformation, perhaps a kind of mixed with water, oil film and encounter magazines such as dirt, will affect the system operation function, and thus should be regular cleaning of hydraulic system.

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

1, clean tubing, should avoid dirt and other impurities, Alto, cotton yarn, mixing tube, influence the function of system.

2. When cleaning the main system, a temporary oil filter shall be installed at the oil return port of the main circuit, and the impurities in the main system will be filtered out again.

3, the main system of cleaning, kerosene, alcohol is not available as cleaning agents, avoid corrosion of hydraulic components, usually with a temperature of 38 DEG C for turbine oil viscosity 20cst as cleaning agent. If the oil temperature increases to 50 degrees -80 degrees centigrade, its cleaning effect will be good.

4, after cleaning, the various departments should restore the original orientation, and clean the tank everywhere, I need to use the equipment specifications new hydraulic oil.

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