The piston part of the hydraulic cylinder needs to extend out of the hydraulic cylinder in the working state, and it will naturally be corroded by oxides and acidic gases. This requires us to coat it with a proper amount of grease for protection, so as to avoid the piston as a load-bearing part. Corrosion and breakage may occur during work. Secondly, change the oil out of the box. Because of long-term use, it is inevitable that foreign matter will enter the hydraulic cylinder, which will increase friction 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 hydraulic cylinder. Cure is not as good as prevention. Therefore, the hydraulic cylinder must be controlled at an appropriate speed, not exceeding 2m/s. This can extend the service life of the hydraulic cylinder. In addition, for the protection of the mechanism and safety, the internal buffer device is very important for the protection of the hydraulic cylinder Effective.
