Key points of the use of seals

Release time2021-10-25Popularity:249


  ① For oil seals used in hydraulic pumps and motor journals, not only the roughness of the sliding surface is required to be within 0.25m, but also hard chromium plating is required on the surface. The oil seal lip needs to be adjusted according to the specific conditions during specific use. The radial spring force of the edge makes it tight enough, and an installation sleeve or a thin gasket is used to protect the sealing ring during installation, so as to prevent the lip from turning over and twisting, causing the spring to slip out.
  ②hydraulic Rolling processing methods are commonly used on the inner surface of the cylinder, which not only improves the surface roughness, but also makes the surface hardened by cold work, which is beneficial to prolong the service life of the seal ring. In addition, the pressure used, the length and type of the sliding surface also have a great influence on the service life. Therefore, the time for the "scheduled inspection" should be determined based on these conditions.
  ③It is required that the sealing surface is in good lubrication state to prevent dirt from invading people. It is also necessary to use oil up to the specified cleanliness level and the correct installation method.
