Mechanical seal (mechanical seal) refers to at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the auxiliary seal to keep fit and slide relative to prevent fluid leakage. Device. The main components include moving ring, static ring, sealing ring, cooling device and compression spring.

The mechanical seal has a large rotating torque, suitable for stirring high viscosity media, and its cost is relatively economical. However, the pressure resistance of mechanical seals is not as good as that of magnetic seals, and can withstand up to 1.6MPa pressure. When used in high temperature conditions, the mechanical seal needs to be equipped with a cooling water jacket for cooling.
