Seal classifiC.A.Tion:

Seals can be divided into two C.A.Tegories: static seals between relatively static joint surfaces and dynamic seals between relatively moving joint surfaces.

There are three main types of static seals: point seals, glue seals and contact seals. According to the working pressure, static seals can be divided into medium and low pressure static seals and high pressure static seals. Medium and low pressure static seals are usually made of softer materials and wider gaskets, while high pressure static seals use hard materials and metal gaskets with a narrow contact width.

Dynamic seals can be divided into two basic types: rotary seals and reciproC.A.Ting seals. According to whether the seal is in contact with the parts that move relative to it, it can be divided into contact seals and non-contact seals. Generally speaking, the sealing performance of the contact seal is good, but limited by friction and wear, it is suitable for the occasions where the linear velocity of the sealing surface is low. Non-contact seals have poor sealing properties and are suitable for higher speeds.
