Applicable working conditions and problem analysis of rubber sealing rings

Rubber materials are used in the development of rubber seals and various rubber and plastic products. The rubber sealing products of DLSEALS Manufacturer include various rubber seals, sealing washers (gaskets), rubber rotating Gley rings (ster seals), oil seals, as well as various specifications and models of O-rings and Y-type sealing rings. and V-shaped sealing ring. With technological research and development and social progress, the technical standards for sealing products are becoming more and more stringent. Sealing technicians reasonably configure sealing materials according to needs to improve sealing performance.

Rubber seals are an elastic polymer material and a key mechanical component in mechanical equipment systems. However, the failure of rubber seals is particularly manifested as seal leakage and seal damage, resulting in seal loss and leakage. When planning the sealing structure, the sealing cross-section is too small and the installation groove cross-section is too large, which will lead to too small compression. Therefore, the installation should reasonably calculate the pipe trench specifications to check the compression amount of the seal.

Rubber seal leaks can be caused by low compression, poor sealing surface quality, improper material selection and installation. The rubber seal, whether it is a gasket or a lip seal, will produce a certain compression deformation according to the seal during the installation process, and it will fit closely with the protruding surface to achieve the purpose of blocking leakage. When the initial compression amount is too small, leakage will occur at low pressure.

Burrs, scratches, low roughness, and unreasonable processing lines on the protruding surface will cause leakage factors. Low-pressure leakage and excessive wear are important causes of damage to the motion seal. In addition to the gloss of the seal surface, rough handling during installation can also cause seal failure.
