hydraulic cylinder sealing device

2. Piston ring sealing: apply for high pressure, high speed situation
3. Seal ring:
    The advantages of hydraulic cylinder sealing device seal ring:1) Convenient to produce and low cost. 2) It can compensate for attrition automatically. 3) Its seal ability can be improved by pressure. 4) It can be used not only in toggle but also in moving parts. 
    The requirement of hydraulic cylinder sealing device seal ring material : It should have good elasticity, have good abrasive performance, with small frictional factor. Oil proof rubber, polyamides and polyurethane are good seal ring material.
    The shape of hydraulic cylinder sealing device seal ring: O ring, Y, and V
    The place where need hydraulic cylinder sealing device seal ring: 1) between piston rod and cylinder grand. 2) rotor.
