Edit:Cixi Highnew Sealing Material Co.,LtdDate:Jun 13, 2017

(1) Select the appropriate sealing material and hydraulic oil, and the adaptability to the working temperature, the compatibility of oil. (2) The geometrical position accuracy (concentricity) of the relative sliding parts of the seals is good (such as hard chromium plating) and the surface roughness is thinner to prolong the service life. Shan for hydraulic pumps, motor shaft neck use of oil seals not only require the roughness of the sliding surface in the RA 0. Within 25m and require hard chromium plating on its surface, in the concrete use also need to adjust the oil seal lip edge of the radial spring force, so that the tightness of the appropriate, but also in the installation of a sleeve or a thin gasket to protect the seal ring, so as to avoid the lip curling, twisting, resulting in spring slide out. The Shan of the inner surface of hydraulic cylinder can not only improve the surface roughness, but also make the surface of cold hardening treatment, which is advantageous to prolong the service life of the sealing ring. In addition, the use of pressure, sliding surface length and type of service life also has a great impact. Therefore, the "check" time should be determined on the basis of these conditions. Shan requires that the seal surface lubrication condition is good, prevents the dirt to invade the human. It is also necessary to use oil and proper installation methods to achieve the required cleanliness level.
