The specific performance of hydraulic seals

The performance of hydraulic seals is as follows: 1. Compatibility: Because hydraulic seals are immersed in hydraulic oil for a long time, they are easy to swell, dissolve or become embrittled and harden, so that they lose their sealing effect. Therefore, hydraulic seals are required to be suitable for Hydraulic oil has good compatibility. 2. Small frictional resistance: In order to avoid or reduce undesirable phenomena such as low-pressure crawling of hydraulic equipment, hydraulic seals are required to have low static frictional resistance and dynamic frictional resistance, and their friction coefficient should be very stable. 3. Small leakage: It is required that the leakage of hydraulic seals is extremely small, has a good sealing effect, and automatically improves its sealing effect as the pressure of hydraulic oil increases. Even in harsh working environments such as high pressure and high temperature, hydraulic seals There was no significant increase in leakage. 4. Low price: Hydraulic seals should be easy to manufacture and install, the corresponding sealing grooves are easy to manufacture, and the requirements for the machining accuracy of the sealing surface are low, and the price is low. 5. Long service life: Hydraulic seals should have good elasticity, heat resistance, cold resistance, pressure resistance, wear resistance and certain physical and mechanical strength, and have a long service life.
