Latest company news about Hydraulic seals commonly used in hydraulic cylinders include O seals, Seal and Combined seals

1 . O seal ring

The cross section of the O type seal ring is O type. The shape is simple, the material is rubber, and the wear resistance is not as good as that of polyurethane, so it is mainly used for static sealing in the hydraulic system.

2. Seal

U - Seal:The sealing performance of U - shaped seal is better, But it is easy to roll, and the friction resistance of U - shaped seal is larger and increases with the increase of working pressure. SO the U type seal ring is only suitable for hydraulic cylinders with low working pressure or low movement speed.

V seal : V seal must be used with support ring and pressure ring. The sealing performance of V ring is better. The number of seal ring can be determined according to the size of working pressure, And the wear of the seal ring can be compensated by pressure ring adjustment. The defects of V seal ring are complex structure and its friction resistance is large. Therefore, The V ring is only suitable for hydraulic cylinders with lower movement speed and higher working pressure.

Y-seal X-seal: They are more than 2 of the section width and height ratio, and based on the requirements for the use of stability, the working lip of They are shorter than the non working lip, Which is divided Rod seals and Piston seals, And thay will not roll when used, so they are suitable for high pressure and high the speed hydraulic cylinder is selected.

 3. Combination seal
 

SPGO (Piston Seals) : It is made up of the superposition of the O rubber sealing ring and the square seal ring filled with polytetrafluoroethylene. SPGO seal can be divided Piston seal and Rod seal, But their sealing mechanism is the same, Which produces higher initial contact stress on the sealing surface according to its own deformation and prevents the pressure free. The leakage of the liquid. When the hydraulic cylinder works, The pressure oil causes the elastic deformation of the O - shaped seal to squeeze the square seal to close the seal surface, And together with the initial contact stress to prevent the leakage of the pressure oil.


HBTS( Buffer Hydraulic Rod Seals) : It is made up of a O rubber seal with a special rectangular or trapezoidal sealing ring filled with polytetrafluoroethylene. It can be divided into the Piston Seal and Rod Seal, As well as the sealing mechanism of the seal and the sealing mechanism. The seal only has one way seal. The characteristics of Stan and Ge Lai ring are filled with PTFE material, with little friction, no crawling and long
time.
