8 things should be paid attention to when installing and using rubber seals?

1. Do not install in the wrong direction and damage the lip. If there are scars above 50μm in the lip seal factory, it may cause obvious oil leakage.

2. Prevent forced installation. It cannot be knocked in with a hammer, but the mechanical seal factory must use a special tool to press the sealing ring into the seat hole, and then use a simple cylinder to protect the lip through the spline part. Before installation, smear some lubricating oil on the lip to facilitate installation and prevent burns during the initial operation of the mechanical seal for the pump, and pay attention to cleaning.

3, to prevent overdue use. The service life of the rubber sealing ring of the dynamic seal is generally 3000 ~ 5000h, and the new sealing ring should be replaced in time.

4. The size of the replacement sealing ring should be the same. It is necessary to strictly follow the requirements of the manual and select the same size sealing ring, otherwise the requirements such as compaction cannot be guaranteed.

5. Avoid using old sealing rings. When using a new sealing ring, it is also necessary to carefully check its surface quality to ensure that there are no defects such as small holes, protrusions, cracks and grooves, and that it has sufficient elasticity before use.

6. During installation, all parts of the opened hydraulic system should be cleaned strictly first, and it is best to use special tools to prevent fingers from being scratched by sharp metal edges.

7. When replacing the sealing ring, the groove of the sealing ring should be strictly checked, the dirt should be removed, and the bottom of the groove should be polished.

8. In order to prevent oil leakage caused by damage, it must be operated in accordance with the regulations, and at the same time, the machine cannot be overloaded for a long time or run in a relatively harsh environment.
