Grooved mechanical face seal

摘要

A seal assembly of the mechanical face seal type has features to reduce leakage across the faces. The seal assembly includes a stationary seal ring through which a rotating shaft passes. A rotating seal ring is mounted around the shaft for rotation therewith. A spring urges the rotating seal ring into contact with the stationary seal ring. A plurality of concentric, nonintersecting grooves are placed on the face of the stationary seal ring to enhance sealing.
