Because the hydraulic cylinder has to bear a lot of pressure, the heavier the load, the greater its pressure. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system.

The hydraulic cylinder is equivalent to the heart of the hydraulic system. It is difficult to repair the problem of the heart, so the maintenance of the hydraulic cylinder should be careful and meticulous.

First of all, to prevent rust. Because the piston part of the hydraulic cylinder is to extend out of the cylinder in the working state, it will naturally be corroded by oxides and acid gases. This requires us to apply an appropriate amount of grease to protect it, so as not to prevent the piston as a load-bearing part Breakage may occur during work due to erosion.

Second, change the oil out of the box. Because of long-term use, it is inevitable that foreign matter will enter the hydraulic cylinder, so that friction will increase during 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 erode the inside of the hydraulic cylinder.
