How To Improve The Sealing of Hydraulic Cylinders Where The Cylinder Barrel And Cylinder Head Meet?

1, the sealing groove bottom diameter should not be too large

If the bottom diameter of the sealing groove processing size is too large, then it will increase the compression allowance of the seal, after assembling it to the hydraulic cylinder, the seal bulging out part will be cut, which will lead to leakage at the interface of the cylinder barrel and cylinder head. Therefore, in order to avoid this leakage, we should use the appropriate size of the inner diameter of the sealing groove, but also pay attention to do a good job of chamfering and cleaning burrs.

2, sealing groove width should not be too narrow

Not only the bottom diameter of the sealing groove is too large to cause oil leakage, the width of the sealing groove if not enough will also lead to oil leakage. Because, when the width is not enough, the hydraulic cylinder sealing ring section will be deformed, and the sealing ring of the stretch will receive a relatively large restriction, the cylinder head in the cylinder wall into the sealing ring when there is no way to press all the grooves, which led to the leakage of oil out. Therefore, in order to improve the sealing of the hydraulic cylinder, do not use too narrow sealing groove.
