Rubber seals are generally divided into static seals and dynamic seals. As the name implies, static seals serve as a seal under static conditions. This type of seal requires good compression deformation of the material; that is, it has good elasticity and requires the product to be twist-proof during assembly. Anti-cutting, according to the working conditions of the product, you can choose the appropriate material and its hardness. Next, Haisheng Rubber will introduce three common classifications of static seals.
O-ring is a commonly used rubber ring . It is used for static sealing in many occasions, and in a few cases for reciprocating sealing and rotary sealing.
It mainly uses nitrile rubber, fluorine rubber, neoprene, ethylene-propylene rubber, silicone rubber and other rubber grades, which can be produced according to national standards, and can also be specially designed and manufactured according to the use environment, so that its pressure range: hydraulic pressure ≤9.8Mpa, pneumatic ≤1Mpa, The temperature resistance range is -60- + 300 ℃. It is resistant to motor oil, various lubricating oils and various chemical media. The impact resistance is greater than 1.5 million times. If the pressure is too high, it can be used in combination with nylon gaskets.
The shape of these seals varies widely, most of them are designed according to the actual use and installation parts, flat and curved. The most commonly used are seals at the joints of pipe fittings, flange seals, and some are used for shock absorption and non-slip. use. Depending on the working environment, different formula materials such as oil resistance, high and low temperature resistance, and aging resistance are selected.
3.Combined sealing gasket
This type of gasket is designed according to the needs of the installation site. The structure of the outer ring with a metal skeleton is generally international. It can also be customized. The outer bone can be made of ordinary carbon steel, stainless steel, or nylon or other plastic parts.
According to the different situations of customers, we Haisheng Rubber will design products according to the actual needs of customers to meet the customized needs of customers. If you have any other questions, welcome to consult on Haisheng Rubber's official website
