Selection Requirements For The Single Wire Seal

Seal selection requirements:

Single Wire Seal  Exporter shares that one is to choose the appropriate seal material and hydraulic oil, as well as the adaptability of working temperature, oil compatibility. The second is the relative sliding parts and seals geometric position precision (concentricity) high material good (such as hard chrome plating) and surface roughness thin can extend the service life.

(1) used for hydraulic pump, motor shaft oil seal not only requires the sliding surface roughness within the Ra is 0.25 m, but also for hard chromium plating on the surface, when used in the specific need according to the specific situation adjust oil seal lip radial force of spring, the elastic moderation, even when installation and installed with a sleeve or shims to protect the sealing ring, lest his lips, twisting, twisted, sliding out in spring.

(2) hydraulic cylinder inner surface commonly used rolling machining method, not only improve the surface roughness, but also make its surface for cold hardening treatment, is conducive to extending the service life of the seal ring. In addition, the pressure used, the length and type of sliding surface also have a great impact on the service life. Therefore, the "scheduled inspection" time should be determined according to these conditions.

(3) requirements sealing surface lubrication state is good, to prevent contamination. It is also necessary to use a clean grade of oil and the correct method of installation.
