Advantages of sealing ring
1. The sealing ring in the working pressure and a certain temperature range, should have good sealing performance, and with the increase of pressure can automatically improve the sealing performance.
2. The friction between the sealing ring device and the moving parts should be small and the friction coefficient should be stable.
3. The sealing ring has strong corrosion resistance, not easy to aging, long working life, good wear resistance, and can be automatically compensated to a certain extent after wear.
4. Simple structure, easy to use and maintenance, so that the sealing ring has a longer life.
