How to deal with the leakage of piston rod in hydraulic cylinder

Update time:2021-04-29Visits:414

  Oil leakage of hydraulic cylinder is a headache for users. However, this problem still occurs frequently. Leakage problem can be divided into internal leakage and external leakage of sealing structure and leakage caused by cylinder damage. For the hydraulic cylinder, the internal piston rod will often fight with various impurities, so it is easy to wear.

  Especially in some poor working conditions, the appearance of the piston rod will adhere to a lot of dust, soil and other substances, some of which will show some hard substances. Therefore, due to the influence of various factors, the piston rod of the hydraulic cylinder will probably have external leakage. The first reason for external leakage is that the structure of shaft combined seal is unreasonable.

  The second important reason is that the gap between the piston rod and the guide sleeve in the hydraulic cylinder is no longer reasonable. For example, the blackening of piston rod surface encountered by many users is actually caused by this reason. From the market research, we found that this factor occupied a large proportion in the cause of piston rod leakage, which once exceeded 60%. Therefore, everyone should be more interested in this issue in the future.

  One component at the end of the piston rod is equal to the appearance of damage, which caused the leakage problem. This is because in practical use, the profile of the piston rod can be definitely damaged in many cases. How can the friction force between the seal ring and the piston rod be increased early, so that the wear flow of the seal ring is effective. This situation is one of the main causes of piston rod leakage in the early stage.

  The above separation from three aspects for you to explain in the process of using the hydraulic cylinder, the main reason for the leakage problem of the external piston rod.
