How to Maintain Hydraulic Press
The hydraulic press is a machine that uses liquid as the working medium and is based on the Pascal principle to transfer energy to realize
various processes. The hydraulic press generally consists of three parts: the machine body (main unit), the power system and the hydraulic
control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.
Hydrautic presses are fndispensable for many forging processes in fndustrial production. especially for tong-term use, which fnevitabfy leads to
loss, so how to clean them is very necessary.
1, Check and clean up
Remove the surface of the hydraulic valve of the small hydraulic press: use a brush, non-metal scraper, silk cloth to remove the surface of the
hydraulic valve and pay attention to the dirt, so be careful not to damage the surface of the hydraulic valve. Do not scratch the mounting
surface of the plate valve.
2. Disassembly
Before disassembling a small hydraulic machine, it is necessary to understand the structure of the hydraulic valve and the connection method
between the parts. When disassembling, remember the positional relationship between the parts and make appropriate marks. Do not
forcefully disassemble to avoid damage to the hydraulic valve.
3. Cleaning
Put the valve body. valve core and other parts of the small hydraulic machine on the tray of the cleaning box, heat the intrusion. and pass the
compressed air into the bottom of the cleaning tank, and wash away the remaining dirt by the stirring action of the air bubbles.
4. Fine wash
Use a high-pressure cleaning solution to clean the solution and finally dry it with hot air. Conditional companies can use existing cleaning
agents, and organic cleaning agents such as diesel and gasoline can be used in individual applications. Some inorganic cleaning solutions
are toxic, heating and volatilization can cause human poisoning, should be used with caution; organic cleaning liquid is flammable, should pay
attention to fire prevention. When selecting the cleaning solution, pay attention to its corrosion resistance, avoid corrosion of the valve body,
and pay attention to the parts after cleaning to avoid rust or contamination of the small hydraulic machine.
