1.1 Mechanical seal (face seal) A device against fluid leakage, composed by keeping close fit and relative sliding for at least a pair of faces vertical to the rotating axis under the action of fluid pressure and compensation mechanism's elastic force (or magnetic force) as well as the matching of auxiliary seal. 1.2 Hydrodynamic mechanical seal Mechanical seal of which the seal face is designed into particular geometric shape and generates hydrodynamic pressure effect through counter rotation.
