Excavator lip seal ring

Excavator lip seal ring The sealing of the lip seal ring is achieved by deforming the lip under the action of liquid pressure and making the lip close to the sealing surface. The higher the liquid pressure, the tighter the lip and sealing surface, the sealing lip wear, with a certain ability to automatically compensate. This kind of sealing ring is often used for reciprocating sealing, and the common Y-shaped and V-shaped sealing rings are used. Basic requirement： In order to ensure the good sealing of the hydraulic system, the basic requirements for the sealing device are as follows: When there is relative movement, the friction caused by the seal should be small, and the friction coefficient should be stable. ② It has good sealing performance in a certain pressure and temperature range, and can automatically improve the sealing degree with the increase of pressure ③ Simple structure, convenient use and maintenance, low cost. ④ Strong corrosion resistance, not easy to age, good wea…
