Sealing modules are widely used in life, basically using mechanical blades to seal. As big as a car, a plane, a small lighter, a mouse, etc. Seals must be used. There are a variety of sealing varieties, according to the raw materials can be divided into: ordinary silicone rubber sealing ring, fluorine rubber sealing ring, ethylene propylene rubber, polytetrafluoroethylene, neoprene and other comparative polyurethane. According to the use can be divided into: acid seal, alkali seal, high temperature seal, low temperature seal, oil seal, etc. Many machines cannot work without a seal, such as an oil seal. If there is no oil seal, it will leak oil and even cause the machine to fail to work. The oil leak is often seen on TV news, in fact, that is, the seal is not good, maybe the quality of the seal is not good. Sealing is an important part of machinery and plays an important role in the operation of equipment. In order to avoid the entry of foreign materials, seals must be used on the machine.
Different sealed modules can work in different environments. Such as high and low temperature environment, acid and alkali solution, oil resistance and so on. In different cases, different materials, such as high temperature resistance of fluorine rubber, should be used for sealing. Important factors Sometimes seal hardness is affected by hair, not all seals are soft, for example, PTFE seals are very hard. Mechanical seals should be checked frequently, and should be replaced in time if abnormalities are found, such as sealing, deformation, cracking, etc. The main factor affecting the service life of the seal is the operating environment. Temperature is the main factor affecting the hardness of the seal. In order to improve the elasticity of the seal at low temperature, the durability of data compression is reduced, and the quality of data is improved. The formula is to add a certain amount of plasticizer to the rubber. Long-term immersion in the operating medium, the plasticizer will gradually be absorbed by the operating medium, forming a seal aging shortened. So always check the sealing module to avoid aging.
