What should you do when the locking piston rod indicates oil leakage during piston rod return?


During use, there may be occasional problems such as oil leakage, oil seepage, scoring, misalignment, seal leakage, and insufficient clearance between the piston rod and the guide bushing.

During use, sometimes due to certain reasons, the piston rod may experience problems such as oil leakage, oil seepage, scratches, misalignment, seal leakage, and insufficient clearance between it and the guide bushing. Below are some solutions.Locking Piston RodLet's look at how to solve oil leakage during the return stroke.
I. Inspection
First, remove the worktable plate underneath, loosen the hose connector, and release the hydraulic oil from the hydraulic cylinder. Then loosen the upper connector to allow the oil to return to the tank, then loosen the cylinder cover below, and use a puller to pull the guide bushing out of the hydraulic cylinder. The guide bushing has two threaded holes.
II. Solutions
Usually, when oil leakage occurs during the return stroke, it is mostly caused by damage to the seal. We can solve this problem by replacing the seal. In addition,Locking Piston RodLet's cover some precautions.
1. The lip of the seal should handle the pressure oil; be careful not to install it backward.
2. When rotating the bushing, pay attention to the chamfer of the piston rod head so that it can be chamfered at the end of the bushing.
3. When inserting the chamfer of the bushing into the guide bushing, the bushing also needs to be pressed onto the lip of the sealing ring. Then insert the guide bushing and bushing into the piston rod together. When it enters the guide bushing, the bushing comes out.
In summary, this isLocking Piston Rodan introduction to some problems of piston rod return oil leakage. I hope that through the above introduction, you can learn more.
