Hello everyone! I am an ordinary technician of Youjiaxin, but I have encountered countless oil cylinder leakage problems. At the beginning, I was repairing the oil cylinder almost every night, which led to many detours and the company also took many detours. Let me share how to solve the problem of hydraulic cylinder leakage.

Fault phenomenon:

     Compared with other hydraulic system failures, the problem encountered by this user is relatively simple. Its hydraulic cylinder has oil leakage. Because this equipment has been used for 8 years, the hydraulic cylinder seal on this equipment may be damaged, or the inner wall of the steel pipe has been worn, so the hydraulic cylinder leaks.

    Fault handling process:

1. According to the observed phenomenon and combined with previous experience, the user needs to replace the seal of the hydraulic cylinder first. The problem is temporarily solved, but it is not used for a long time. After a period of time, the oil leakage occurs again.

2. The root cause is analyzed. The problem is not on the piston of the hydraulic cylinder, but on the seal at the end of the hydraulic cylinder.

3. During the careful inspection, it was found that there were many pits and grooves on the sealing surface of the guide sleeve due to wear, which increased the sealing gap between the guide sleeve and the piston rod and failed to reduce pressure, so that the high-pressure oil inside the hydraulic cylinder directly impacted the primary and secondary sealing rings. It is conceivable that the sealing ring was damaged in a very short time under the action of high-pressure oil, so the oil leakage phenomenon occurred repeatedly.

Summary:

      Because the inside of the hydraulic cylinder is full of various precision parts, there are more than a dozen large and small seals. If the size is not suitable, it will cause oil leakage after a period of use. The degree of wear on the inner wall of the steel pipe will also have a great impact on the oil leakage of the cylinder. For example, the piston seal has been worn, so that the steel part of the piston directly touches the inner wall, causing the inner wall to be severely scratched. During use, it may also cause the axis to bend.

       After sharing so much content, as a master, do you understand it? Calculate how many days you spent repairing this cylinder? In addition, how long did the production line stop and how much production was delayed? Therefore, I still recommend that when the cylinder is broken, you should immediately contact the hydraulic cylinder manufacturer to quickly discuss repairs or replacements, so as not to delay the company's production output.
