Uses of seals

Seals are widely used in life. Basically, the seals will be used when they are in contact with the machinery. It's as big as a car plane, as small as a lighter mouse and so on. All have to use seals. There are many types of seals, which can be divided according to raw materials: comparison of common silicone rubber seals, fluororubber seals, ethylene propylene rubber, polytetrafluoroethylene, chlorine mechanical seal models, butadiene rubber, polyurethane and so on. It can be divided into acid resistant seals, alkali resistant seals, high temperature resistant seals, low temperature resistant seals, oil resistant seals, etc. Many machines can't work without seals, let's say oil seals, if there is no oil seal, oil may leak, and even the machine can't work. I often see news of crude oil leaking on TV. In fact, it means that the seals are not done well, maybe the quality of the seals is not enough. Seals are an important part of machinery and have an important effect on the operation of instruments. In order to avoid the entry of foreign objects into the metal bellows mechanical seal, it is necessary to use seals in the machine.

    Seals with different uses can be imported mechanical seals to work in different environments. For example, high and low temperature environment, acid and alkali solutions, oil resistance, etc. Select different materials for seals working in different environments, such as the high temperature resistance of fluoroelastomer. Sometimes the hardness of the seal is also an important factor that affects the use of life. Not all seals are soft, for example, PTFE seals are very hard. Mechanical seals should be checked frequently, and abnormalities should be replaced in time. For example, seal deformation, cracking, etc. The main factor affecting the service life of seals is the operating environment. Temperature is the main factor affecting the hardness of the seal. In order to add the elasticity of the seal at low temperature and reduce the permanentness of the data tightening, it is necessary to improve the formula of the data, and a certain amount of plasticizer must be added to the rubber. When immersed in the running medium for a long period of time, the plasticizer will be gradually absorbed by the running medium, resulting in shortened aging of the seal. So seals should be checked frequently. Avoid aging to form incidents.
