Description of the correct use of hydraulic seals

The correct use of hydraulic seals is mainly:
First, the leakage is very small, the leakage of the hydraulic seal is very small, and it has a good sealing effect, and automatically improves the sealing effect with the increase of the pressure of the hydraulic oil, even in the harsh working environment such as high pressure and high temperature, the hydraulic seal There was no significant increase in the amount of leakage.
Second, good compatibility Because the hydraulic seals are immersed in the hydraulic oil for a long time, it is easy to swell, dissolve or embrittlement and harden, so that it loses the sealing effect. Therefore, the hydraulic seals are required to have good compatibility with the hydraulic oil. .
Third, the frictional resistance is small to avoid or reduce the low pressure creeping of hydraulic equipment, etc., the hydraulic seals are required to have low static friction resistance and dynamic friction resistance, and the friction coefficient should be very stable.
