Since 2006, Focus on rubber seals

The performance of hydraulic seals

by:ORK      2022-11-14
Minimal leakage requires the hydraulic seal [1] to have a very small leakage, good sealing effect, and automatically improve its sealing effect as the pressure of the hydraulic oil increases, even in harsh working environments such as high pressure and high temperature, the hydraulic seal There is no significant increase in the leakage of the parts. Good compatibility is because the hydraulic seal is immersed in hydraulic oil for a long time, it is easy to swell, dissolve or become brittle and hard, so that it loses its sealing effect. Therefore, the hydraulic seal is required to be suitable for Hydraulic oil has good compatibility. Small friction 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 friction resistance and dynamic friction resistance, and their friction coefficient should be very stable. Long service life Hydraulic seals should have good elasticity, heat resistance, cold resistance, pressure resistance, wear resistance and certain physical and mechanical strength, etc., and have a long service life. Low-cost hydraulic seals should be easy to manufacture and install, and their corresponding The sealing groove is easy to process and manufacture, and the requirements for the machining accuracy of the sealing surface are low, and the price is low.
