How to install bottle blowing pressure retaining sealing ring

The correct way to install the hydraulic sealing ring is as follows:

1. Check the relevant surfaces of piston, cylinder barrel and installation guide sleeve to ensure that they are clean and free of burrs and edges.

2. The installation tool should be smooth, without sharp edges and corners, so as to ensure that the seal will not be damaged in any form during installation.

3. During installation, a small amount of grease can be applied to the relevant surfaces of the seal and cylinder barrel to facilitate installation, but no grease is allowed to remain between the rubber elastomer and the sliding sealing ring, otherwise the sealing performance will be affected.

4. Whether installed vertically or horizontally, the concentricity of piston and cylinder should be maintained. Excessive eccentricity may damage the seal.

5. The installation speed should not be too fast, otherwise the seal will be damaged.
