Hydraulic cylinder in the process of work its working principle is to take the hydraulic oil as the transmission medium, in the use of the main pump will be used to pressurize the hydraulic oil, control valve transfer to each working device for work, the energy transmission of the whole machinery plays a very key role.

Hydraulic cylinder in order to achieve its better work, the hydraulic components will be higher requirements, requirements for cleanliness and oil quality is also very high, and the pressure suffered by the hydraulic cylinder is very big, do a good job in the maintenance of the hydraulic cylinder is a very important part of the maintenance of the hydraulic system facade.

1. In the process of using the hydraulic cylinder, the filter screen and hydraulic oil of the cleaning system should be changed regularly and timely to ensure the cleanliness of the cylinder and extend its service life.

2. The hydraulic cylinder needs to do a good job in rust prevention. The piston part of the hydraulic cylinder will be corroded by oxides and acidic gases in the working state, so we need to coat it with grease to protect it from component breakage.

3. Control system temperature. Too high oil temperature in the hydraulic cylinder will reduce the service life of the seals, if the long-term oil temperature is too high will even make the seals long-term deformation, resulting in complete failure.

4. The hydraulic oil needs to be replaced regularly and used for a long time. It is normal for foreign bodies to enter the hydraulic cylinder.

5. To a certain extent, the hydraulic cylinder needs to do a good job of protecting the piston rod, so as to effectively prevent the external damage of the seals. To a certain extent, it is necessary to regularly clean up the sand, so as to prevent the dirt that is not easy to clean from entering the inner cylinder to damage the piston or the seals.

6. Lubricate the connection part regularly to prevent abnormal wear and corrosion in oil-free state.

7. Check the connection parts such as thread regularly, once loose phenomenon is found, it needs to be tightened immediately.
