Cleaning method of hydraulic components during maintenance of hydraulic press

The hydraulic press has a wide range of uses, because the precision of the original hydraulic press is high, and the gap between the moving parts is small. If impurities or metals are mixed in during installation, it will cause the hydraulic components to wear out or get stuck, and even cause mechanical damage in severe cases. Therefore, before the hydraulic components are installed, it is necessary to clean the hydraulic components once.

After a long-term use and operation of the hydraulic system, due to the aging and deterioration of the hydraulic oil of the hydraulic press, there may be some kind of dirt mixed with water, film and oil, which will inevitably affect the working function of the system, so the hydraulic system should be cleaned regularly. .

Cleaning method of hydraulic components during maintenance of hydraulic press:

1. When cleaning the oil pipe, it is necessary to avoid dirt and impurities such as cotton yarn sticks, which are mixed into the pipe and affect the function of the system.

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

3. To clean the main system, do not use kerosene, alcohol, etc. as cleaning agents to avoid corrosion of hydraulic components. Usually, turbine oil with a temperature of 38°C and a viscosity of 20cst is used as the cleaning agent. If the oil temperature is raised to 50℃-80℃, its cleaning effect will be good.

4. After cleaning, each department should restore its original position, and clean the fuel tank everywhere, and add new hydraulic oil to meet the requirements of the equipment instruction manual.

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