Seal ClassifiC.A.Tion:

(1) According to whether the seal is in contact with its relative moving parts, it can be divided into contact seal and non-contact seal; according to the seal and contact position, it can be divided into circumferential seal and end face seal. End face seal is also called mechanical seal. The centrifugal seal and spiral seal in the dynamic seal are sealed by powering the medium when the machine is running, so they are sometimes called dynamic seals.

(2) Static seal: There are three main C.A.Tegories: gasket seal, sealant seal and direct contact seal. According to the working pressure, static sealing can be divided into medium and low pressure static sealing and high pressure static sealing. Medium and low pressure static seals usually use softer and wider gasket seals, while high-pressure static seals use harder metal gaskets with a narrow contact width.

(3) Dynamic seal: It can be divided into two basic types: rotary seal and reciproC.A.Ting seal.
