Hydraulic cylinder in the work, inevitably there will be some problems, once the problem, how do we analyze the solution? Master this knowledge is very important, it can help us better use the hydraulic cylinder, reduce the use of some resistance in the process of using, then the following to analyze when the hydraulic cylinder crawling phenomenon how we should deal with?

The reasons and solutions of creeping phenomenon of hydraulic cylinder are as follows:

1. When air is mixed in the hydraulic cylinder, an exhaust device should be added in the hydraulic cylinder to eliminate air.

2. If the tightness of the sealing ring is not suitable, too tight or too loose, it should be adjusted to fit.

3. The piston and piston rod coaxiality is not good, at this time should adjust the piston and piston rod coaxiality.

4. If the hydraulic cylinder and guide rail are not parallel, the hydraulic cylinder should be reinstalled or adjusted.

5. If the piston rod is too rigid or bent, the diameter of the piston rod should be increased or straightened.

6. If the clearance between the moving parts of the hydraulic cylinder is too large, or the installation position is offset, the clearance should be adjusted or corrected.

7. If corrosion or burr occurs in the hydraulic cylinder, the burr and rust should be removed.

8. If the nut is screwed tight, loosen the nut appropriately to make it tight.
