Hydraulic cylinder Oil leakage is a headache for flooded users, but this problem will still occur repeatedly. Leakage problems can be divided into internal leakage and external leakage of sealing structure and oil leakage caused by cylinder damage. As for the hydraulic cylinder, its internal piston rod will often fight with various impurities, so it is simply worn.

Especially in some working conditions compared with the vulgar environment, the appearance of the piston rod will stick a lot of dust, mud and other substances, and some of them will show some hard substances. Therefore, due to the influence of various factors, the piston rod of the hydraulic cylinder may have external leakage. The reason for external leakage is that the structure of shaft combined seal is unreasonable.

The second reason is that the clearance between the piston rod and the guide sleeve in the hydraulic cylinder is no longer reasonable. For example, the blackening of the piston rod surface that many users encounter is actually caused by this cause. From the market research, we found that this element accounted for a large proportion in the causes 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 is equal to the leakage problem caused by the damage to the appearance of the piston rod. This is because in actual use, many cases can definitely damage the piston rod's contour, 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 will be effective. This is one of the main reasons for the initial leakage of the piston rod.

The above separation explains the main reasons for the leakage of the external piston rod in the process of using the hydraulic cylinder from three aspects. I hope that users and friends will pay attention to this problem and try their best to prevent the piston rod from leaking.
