??Hydrogenated nitrile rubber ceramics factory hydraulic o-rings

??The structure of hydraulic seals and sealing mechanism at present, the ceramic factory is widely used hydraulic seals are mainly sealing pressure type hydraulic seals, sealing of close hydraulic seal?Lip seals? And they are a combination of both? Three types of combination of the seals.

??Sealing clamp type hydraulic seals and sealing mechanism of the ceramics factory commonly used hydraulic machinery hydraulic cylinder sealing clamp type hydraulic seals mainly ring circular sealing ring and rectangular sealing ring, they have some advantages such as simple structure, easy manufacturing, low cost, so they are hydraulic transmission system is widely used in the dynamic and static seal the sealing element. They installed in the sealing groove is usually produce 10-25% of the radial compressive deformation, and the sealing surface is relatively high initial contact stress, there is no pressure to prevent leakage of liquid.

??Lip seal at present, the ceramic factory hydraulic machinery hydraulic cylinder commonly used lip seals is primarily a v-shaped sealing ring, u-shaped seal ring, Y type sealing ring and YX ring, etc.

??V-shaped sealing ring of v-shaped sealing ring has good sealing performance, according to the size of the sealing ring used to determine the number of job stress, usually must be by means of the adjustment of the gland to compensate the wear of sealing ring, its deadly weakness is complex, usually by the bearing ring, sealing ring and pressure ring of three parts, the frictional resistance is larger and increases with the increase of working pressure and seal number and. So the v-shaped sealing ring is only suitable for low speed and higher working pressure of the hydraulic cylinder.

??U-shaped ring u-shaped seal sealing performance is good, but used alone is easy to roll, so need to be used with tin bronze quality bearing ring, the frictional resistance and increases with the increase of working pressure and larger. So U seal only suitable for the working pressure is low or speed low hydraulic cylinder.

??Y-shaped sealing ring y-shaped sealing ring is relying on its open the lips pressed and keep the seal on the sealing surface, usually can be used alone, the sealing performance is good, small friction resistance, good compression performance, work stability, long service life. So the y-shaped sealing ring is suitable for high speed variable pressure, large diameter, large stroke of the hydraulic cylinder.
