Prevent overdue use. The service life of rubber seals for dynamic seals is generally 3000~5000h, and new seals should be replaced in time.
The size of the replacement seal should be the same. It is necessary to strictly follow the requirements of the instructions, and select the same size of the sealing ring, otherwise the tightness and other requirements cannot be guaranteed.
Avoid using old seals. When using a new sealing ring, carefully check its surface quality to ensure that there are no defects such as small holes, protrusions, cracks and grooves, and have sufficient elasticity before using it.
When installing, you should strictly clean all parts of the opened hydraulic system. It is best to use special tools to prevent fingers from being scratched by sharp metal edges.
When replacing the sealing ring, check the groove of the sealing ring strictly, remove the dirt, and polish the bottom of the groove.
In order to prevent damage and cause oil leakage, it must be operated in accordance with the regulations. At the same time, the machine cannot be overloaded for a long time or run in a relatively harsh environment.
