するメカニカルシール。In a mechanical seal formed by sliding and rotating a seat ring and a driven ring, the sliding surfaces of the seat ring and the driven ring, or either one of the rings, have a material, thermal expansion coefficient, or wear resistance of the sliding surface. Forming a pattern made of different materials extending in a relative rotation direction and an inclined radial direction, and forming a flat sliding surface with the pattern,
A mechanical seal characterized in that narrow grooves in the above pattern are generated on the sliding surface due to differences in thermal expansion coefficient or wear resistance during operation of the mechanical seal, and sealing is achieved by the pumping action of the grooves.
