Sealing ring


The sealing ring should have good sealing performance in the working pressure and certain temperature range, and can automatically improve the sealing performance with the increase of pressure.

The friction between the sealing ring device and the moving parts should be small and the friction coefficient should be stable.

Sealing ring anti-corrosion ability, not easy to aging, long service life, good wear resistance, after wear can be automatically compensated to a certain extent.

Prevent forced installation. Do not use a hammer, but use a special tool to press the seal ring into the hole, and then use a simple cylinder to protect the lip through splines. Before installation, apply lubricating oil to the lips to facilitate installation and prevent burns during initial operation. Pay attention to cleaning.

Prevent overdue use. The service life of rubber seals with dynamic seals is generally 3000 ~ 5000h, and a new sealing ring should be replaced in time.

The size of the replacement ring should be consistent. To strictly follow the requirements of the manual, choose the same size of the sealing ring, otherwise can not ensure the tightness and other requirements.
