Seal ring is the general name of dynamic ring and static ring, which is the most important component of mechanical seal. The seal ring largely determines the performance and life of the mechanical seal; therefore, some requirements are made for it.

Mechanical seal is a device to prevent fluid leakage consisting of at least one pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and compensation mechanism elasticity (or magnetic force) and the cooperation of the auxiliary seal to maintain the fit and relat
