Because hydraulic cylinders have to withstand high pressure, the heavier the load, the greater its pressure. Therefore, doing a good job in the maintenance of hydraulic cylinders is an important part of the maintenance of the entire hydraulic system.

The hydraulic cylinder is equivalent to the heart of the hydraulic system, and if there is a problem with the heart, it is difficult to repair. Therefore, the maintenance of the hydraulic cylinder should be careful and meticulous.

Firstly, rust prevention is necessary. Because the piston part of the hydraulic cylinder needs to extend out of the cylinder during operation, it will naturally be corroded by oxides and acidic gases. This requires us to apply an appropriate amount of grease to protect it, so as to prevent the piston as a load-bearing component from being corroded and may break during operation.

Secondly, it is necessary to open the box and change the oil. Due to long-term use, it is inevitable that foreign objects will enter the hydraulic cylinder, resulting in increased friction during use. In addition, hydraulic oil also has a certain service life. Failure to change oil for a long time can damage or erode the interior of the hydraulic cylinder.

Prevention is better than cure, so in the operation of hydraulic cylinders, the speed should be controlled appropriately, not exceeding 2m/s, which can extend the service life of hydraulic cylinders. In addition, for the protection of the mechanism and safety reasons, the installation of internal buffer devices is effective for the protection of hydraulic cylinders.
