Briefly analyze the application and performance of hydraulic seals. Because hydraulic seals such as hydraulic O-rings, hydraulic square rings and hydraulic circular rings are simple in shape, easy to manufacture and low in cost, they are widely used in hydraulic transmission systems. Components and static sealing elements.
1, they have a good seal, even in the case of high temperature and high pressure and corrosion, it will ensure that the liquid material inside will not easily leak.
2. Require them to have good oil resistance. If it is not resistant to oil, the hydraulic seal will be immersed in the hydraulic oil for a long time, and it will swell, dissolve or embrittle and harden, and lose the sealing effect.
3. They are required to have a small coefficient of friction. If the dynamic friction coefficient and the static friction coefficient are high, there is a possibility that the hydraulic equipment may cause low-pressure creeping and the like.
