Because the hydraulic cylinder must bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful. first, Xining Hydraulic machinery Rust prevention is required. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally suffer from oxidation Xining Hydraulic machinery Manufacturer The erosion of acid gas requires us to apply proper amount of grease to protect it.
If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Xining Hydraulic machinery Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Xining Hydraulic machinery Manufacturer The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.
For the selection of hydraulic cylinder, the hydraulic cylinder will be selected according to the inner diameter, stroke, operating pressure and installation type during the selection of hydraulic cylinder. In fact, in addition to these, we should pay attention to the following points. First, when the hydraulic cylinder is loaded and then the actuating speed reaches a certain standard, Xining Hydraulic machinery Hydraulic cylinder with buffer device must be used. Or when the speed reaches a higher speed, a deceleration valve must be installed outside the hydraulic cylinder; Secondly, carefully select hydraulic oil and oil seal. Oil seals of different materials are selected for different hydraulic oils, Xining Hydraulic machinery Manufacturer To ensure the service life of the hydraulic cylinder.
Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Xining Hydraulic machinery Manufacturer It is necessary to have a correct understanding of this kind of hydraulic cylinder and have a certain understanding, so that we can know how to use it reasonably and make full use of it. This kind of hydraulic cylinder has corresponding operation regulations and maintenance regulations, because it is in the hydraulic cylinder category. In addition, Xining Hydraulic machinery It is necessary to have a clear and comprehensive understanding of its operation and maintenance procedures. The symptom of strain and wear is that the lifting speed of the equipment is relatively slow, accompanied by self subsidence.
1、 If the groove is too deep, two situations will occur: A. If the gap between the seal root and the groove becomes larger, the seal root will become unstable. B. The interference between the sealing lip and the sealing surface becomes smaller, Xining Hydraulic machinery The rebound force of the seal becomes smaller, and the failure rate of low-pressure oil leakage will increase when the piston rod jumps. 2、 If the groove is too shallow, two situations will also occur: A. The interference between the sealing lip and the sealing surface will increase, and the contact area will increase, which will lead to greater friction, Xining Hydraulic machinery Manufacturer The increased heat accelerates the damage of the seal lip. B. As a result, the clearance at the seal root becomes smaller, and the probability of the seal root being squeezed out when the oil cylinder is under high pressure increases.
