Structural characteristics of the mechanical seal

From the structural characteristics of view , the mechanical seal type varied, but by component speaking, it mainly has the following four basic elements:
1 , the buffer compensation unit
A spring element which consists of the main buffer compensation mechanism , which is to maintain the important mechanical truck sealseal normal conditions .
2, the sealing unit
I.e. the rings of the ring and stationary seal faces , which is the core of the mechanical seal .
3 , the auxiliary sealing unit
The ring seal and the static ring seals and other components, it is to solve than the sealing face , the site of leakage possible auxiliary sealing means is a mechanical seal elements indispensable .
Mechanical seal is a fluid sealing technology promising a plastic seals sealed form , has now reached working pressure of 40MPa, face mean sliding velocity 150m / s, pv value of 200MPa • m / s level. Can meet the requirements of most production process conditions .
4 , the drive unit
By the sleeve , button or pin consisting of a fixed transmission mechanism , it is to achieve the ring rotates with the shaft a reliable guarantee , but also a prerequisite to achieve dynamic seal .
