What are the factors that affect the use of high quality rubber seals?

- Jul 31, 2018-

  High-quality rubber seals are a common type of basic component in sealing devices and play a very important role in the contradiction between leakage and sealing. Solve leaks and seals during human conquest of nature. An important way to promote technological advancement and prevent and reduce environmental pollution. High quality rubber seals are a class of rubber products that are widely used in sealing technology. Because rubber has a valuable elastic polymer material, a wide temperature range, giving less stress in different media will produce large deformation, which can provide contact pressure, compensate for leakage gap, and achieve the purpose of sealing. .

  The main products currently have rubber seals, rubber gaskets, flange gaskets, rubber shock absorbers, rubber O-rings, V-rings, X-rings, Y-rings, and other forms, sizes, colors, hardness and Rubber products of materials, although our high-quality rubber seal products started relatively slowly, with the advancement of society, the emergence of new sealed production equipment and technology, the technical requirements for sealing products are becoming more and more demanding, thus further promoting new products. Development and development. High quality rubber seals are a class of rubber products that are widely used in sealing technology. Because rubber has a valuable elastic polymer material, a wide temperature range, giving less stress in different media will produce large deformation, which can provide contact pressure, compensate for leakage gap, and achieve the purpose of sealing. .

  1. The temperature and friction under working conditions are difficult to describe the higher service temperature of the seal material, because this is the result of a combination of different factors of the seal specification model. For pistons and piston rods operating at different temperatures, separate their specifications. Secondly, the surface roughness of the seal product, surface characteristics, pressure, medium, temperature, seal material and type and running speed are all factors that affect the seal.

  2, external pressure is an important main reason affecting the quality of the seal, the pressure level, the pressure cycle of different levels, has an impact on the seal damage. The higher the pressure, the greater the factors affecting the seal because it drives other sealing factors such as temperature, speed, seal material, and the gap between the seals, the gap between the piston and the cylinder head.

  3. For the treatment of the surface of the seal, experience tells us that the characteristics of the cylinder piston and piston rod surface have a very large impact on the life of the seal.
