Information

The seal can be divided into two categories: the static sealing between the relative stationary joint surfaces and the moving seals between relative motion joints. The static seal is mainly a kind of seal, glue seal and contact seal. According to the work pressure, the static seal can be divided into middle and low pressure static seal and high pressure static seal. Medium and low pressure static seal commonly used material is soft, the gasket is wider than the gasket seal, the high pressure static seal USES the material harder, the contact width is very narrow metal gasket. Movable seal can be divided into two basic types: rotary seal and reciprocating seal. According to the contact of the parts of the relative motion of the seals, it can be divided into contact seal and non-contact seal. Generally speaking, the sealing of contact seal is good, but it is restricted by friction wear, and it is suitable for the situation where the sealing surface is lower. Non-contact sealing is poor sealing, suitable for high speed occasions.
