Product Description

Part No.

The correct method of installing the hydraulic sealing ring is as follows:

1. Check the relevant surfaces of the piston, cylinder and installation guide sleeve to ensure that they are fully clean, burr-free and edgeless.

2. The installation tools shall be smooth, edgeless and sharp to ensure that the seals will not be damaged in any form during the installation process.

3. A small amount of grease can be put on the relevant surface of the seals and cylinder to facilitate installation, but the residual grease is not allowed between the rubber elastomer and the sliding seal ring, otherwise it will affect the sealing performance.

4. Whether vertical or horizontal installation should maintain the coaxiality of the piston and cylinder, too much eccentricity is likely to damage the seal.

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

Main cause of leakage

Selection of seals

1. The pressure is too high and the seal is too hard to be extruded into the metal groove.

2. the sealing material and the medium are dissolved, and the seals are softened or dissolved.

3. seals used in the condition of high temperature, sealing material is carbonized.

4. low temperature leads to sealing material hardening, shrinkage and leakage.

5. Using too high linear speed leads to heating, dry grinding, carbonization and leakage of seals.

6. Poor lubrication in service condition leads to wear and leakage of seals.

7. The cavity used is subjected to vibration and causes leakage.

8. Leakage is caused by wear of seals caused by dust.
