Regarding the selection of rebound hydraulic cylinders, we usually choose according to the inner diameter, stroke, working pressure and installation form of the product. In fact, in addition to these, there are the following points that are worthy of our attention. First, when the operating speed of the hydraulic cylinder after rebounding is above a certain standard, it is necessary to select a cylinder with a buffer device. Or it must be installed outside the hydraulic cylinder when a higher speed is reached, and a reduction valve should be installed. At the same time, we must pay attention to select the appropriate hydraulic oil and oil seal. Different hydraulic oils use oil seals of different materials to ensure the life of the rebound hydraulic cylinder. Of course, it needs to be well maintained during use. Considering that the cylinder needs to withstand greater pressure, when the load is heavier, the pressure will be greater. Therefore, the maintenance of the oil cylinder will be the most important part of the maintenance of the entire hydraulic system.
In fact, for the hydraulic system, the rebound hydraulic cylinder is like a heart. If a heart problem is difficult to repair, its maintenance needs to be cautious and meticulous. First of all, we must pay attention to anti-rust during maintenance. This is because the piston part needs to extend out of the cylinder in the working state, and it will naturally be eroded by oxides and acid gases. This requires us to apply appropriate amount of grease to protect it from the piston as a load-bearing component. Erosion may cause breakage during work. Secondly, with the extension of use time, sometimes some foreign objects may be mixed into the rebound hydraulic cylinder, so that the friction will increase during its operation. And the hydraulic oil itself also has a certain service life, so the oil needs to be changed regularly to avoid negative impact on the device. In general, during the period of use, we must do a good job of prevention in advance. Moreover, the operating speed of the rebound hydraulic cylinder also needs to be properly controlled, so that the service life of the rebound hydraulic cylinder can be extended. In addition, in order to protect the mechanism and safety, the internal installation of buffer devices is also very effective for the protection of the oil cylinder.
