Anti-rust work and use process of hydraulic cylinder
The working principle of the hydraulic cylinder in the process of work is to use hydraulic oil as the transmission medium, the main pump is used to pressurize the hydraulic oil, and the conversion of the control valve is transferred to each working device for work, which plays a very key role in the energy transmission of the whole machinery.
In order to achieve its better work, the hydraulic cylinder will have higher requirements for hydraulic components, cleanliness and oil quality requirements are also very high, and the pressure of the hydraulic cylinder is very large, and the maintenance of the hydraulic cylinder is a very important part of the maintenance facade of the hydraulic system.
1. The hydraulic cylinder should be replaced regularly and timely during the use of the cleaning system filter and hydraulic oil to ensure the cleanliness of the cylinder and extend its service life.
2. The hydraulic cylinder needs to do a good job of rust prevention. The piston part of the hydraulic cylinder will be eroded by oxide and acid gas in the working state. We need to coat it with grease for protection to avoid the occurrence of broken parts.
3. Control the system temperature. The high oil temperature in the hydraulic cylinder will reduce the service life of the seal, and if the oil temperature is too high for a long time, the seal will even be deformed for a long time, resulting in complete failure.
4. Hydraulic oil needs to be replaced regularly, long-term use, if there is a foreign body into the hydraulic cylinder is a very normal phenomenon, we should replace the hydraulic oil in a timely and regular manner, otherwise the foreign body in use will increase friction, and long-term do not change the oil on the hydraulic cylinder is corrosive damage.
5. The hydraulic cylinder needs to do a good job of protecting the piston rod to a certain extent, so that it can effectively prevent the external damage of the seal, and to a certain extent, it is necessary to often clean up the sand, so that it can prevent the dirt that is not easy to clean into the cylinder to damage the piston or the seal.
6. Lubricate the connection part regularly to prevent abnormal wear and rust in the oil-free state.
7. Regularly check the connection parts such as the threads, and once the phenomenon of loosening is found, it needs to be fastened immediately.
