Information
The hydraulic seals are mainly O-rings, round rings and square rings, which make them simple in structure, easy to manufacture and low in cost. Therefore, they are widely used in the hydraulic system of hydraulic station as dynamic and static sealing elements. It is because of such structural characteristics that their performance characteristics are created.
 
1. It makes the liquid substance in it not easy to leak and has good sealing performance. Even in the harsh working environment such as high pressure and high temperature, the leakage of the hydraulic seal does not increase significantly.
 
2. Good compatibility. Because the hydraulic seal is immersed in the hydraulic oil for a long time, it is easy to swell, dissolve, embrittle and harden, which makes it lose the sealing effect, so it is required that the hydraulic seal has good compatibility with the hydraulic oil.
 
3. It has the advantage of small friction. In order to avoid or reduce the low-pressure creeping and other undesirable phenomena of hydraulic equipment, it is required that hydraulic seals have low static friction resistance and dynamic friction resistance, and their friction coefficient should be very stable.
