The hydraulic cylinder is equivalent to the heart of the hydraulic system, and it is difficult to repair the heart problem, so the maintenance of the hydraulic cylinder is to be careful and meticulous.
First of all, it is necessary 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 eroded by oxide and acid gas, which requires us to apply an appropriate amount of grease to protect it, so as to avoid the piston as a load-bearing part being eroded and may break during work.
Secondly, it is necessary to change the oil in the box. Because of long-term use, it is inevitable that foreign objects will enter the hydraulic cylinder, so that friction will increase in use, in addition, hydraulic oil also has a certain service life, long-term oil change will damage or erode the inside of the hydraulic cylinder.
It is better to control the speed in the work of the hydraulic cylinder than to prevent it, so that the speed should be controlled appropriately, not more than 2m/s, which can extend the service life of the hydraulic cylinder, and in order to protect the mechanism and safety, the internal installation of the buffer device is very effective for the protection of the hydraulic cylinder.
