What kind of seals are divided into?
According to the type of sealing structure, sealing mechanism, seal shape and material, the classification of seal is:Static seal1. gasket sealing (1) non-metallic gasket (2), metal metal composite gasket (3), metal gasket2. glue seal3. packing seal4. bellows
Dynamic seals can be divided into rotary seal and reciprocating seal two basic types.According to the seal of the relative movement of the parts is divided into sealing contact, contact and non-contact seal; according to the seal and the contact position can be divided into circumferential seal and the seal, the seal is also called mechanical seal. The centrifugal seal and spiral seal in the dynamic seal are sealed by the power of the medium when the machine is running, so it is sometimes called the power seal.
Seals can be divided into two categories: static seal and dynamic seal.Static seals are mainly gasket seal, sealant sealing and direct contact sealing three categories.According to the work pressure, static seal can be divided into medium and low pressure static seal and high pressure static seal. Low and medium pressure static seals are usually made of soft and wide width gasket. High pressure and static seals are made of hard material and metal gaskets with narrow width.
