The role and significance of hydraulic seals
In hydraulic systems, seals are used to prevent leakage of working media and ingress of foreign dust and foreign matter. The element that acts as a seals.DSH Seals share the role and significance of hydraulic seals with you.
Outer leakage can cause waste of working media, contaminate machines and the environment, and even cause mechanical failures and equipment accidents.
Internal leakage can cause a drastic drop in the volumetric efficiency of the hydraulic system, failing to reach the required working pressure, or even working.
Intrusion of tiny dust particles in the system can cause or exacerbate the wear of the friction elements of the hydraulic components, further causing leakage.
Therefore, seals and sealing device are an important part of hydraulic equipment. The reliability and service life of its work is an important indicator of the quality of the hydraulic system.
In addition to the gap seal, the seal is used to control the gap between the adjacent two coupling surfaces below the minimum gap through which the liquid to be sealed can pass.
In the contact seal, it is divided into two types, self-sealing compression type seal and self-sealing type self-tightening type seal(for example lip seal).
