Because the hydraulic cylinder has to bear a lot of pressure, the heavier the load is, the greater the pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the whole hydraulic system. The hydraulic cylinder is equivalent to the heart of the hydraulic system, the heart is difficult to repair, so the maintenance of the hydraulic cylinder is to be careful. First of all, rust prevention. Because the piston part of the hydraulic cylinder is to extend out of the cylinder in the working state, it will be naturally eroded by oxide and acid gas, so we need to coat it with proper amount of grease for protection, so as to avoid the piston as a load-bearing component from being eroded and may break in the work.

Secondly, open the box and change the oil. Because of long-term use, it is inevitable that foreign matters will enter into the hydraulic cylinder, which will increase the friction in use. In addition, the hydraulic oil also has a certain service life. If the oil is not changed for a long time, it will damage or corrode the inside of the hydraulic cylinder. Therefore, in the work of the hydraulic cylinder, the speed should be controlled properly, not more than 2m / s, which can extend the service life of the hydraulic cylinder. In addition, in order to protect the mechanism and safety, the internal installation of buffer device is very effective for the protection of the hydraulic cylinder.
