The mechanical seal is a shaft sealing device that relies on a pair or several pairs of end surfaces that slide relative to the shaft perpendicularly to the shaft under the action of the fluid pressure and the elastic force (or magnetic force) of the compensation mechanism to maintain a fit and to be equipped with an auxiliary seal to achieve leakage prevention.
Common mechanical seal structure is composed of stationary ring (static ring), rotating ring (moving ring), elastic element spring seat, tightening screw, rotating ring auxiliary sealing ring and stationary ring auxiliary sealing ring, etc. The anti-rotation pin is fixed on the gland To prevent the stationary ring from rotating.
Rotating rings and stationary rings can often be called compensation rings or non-compensation rings depending on whether they have axial compensation capabilities.
