MECHANICAL SEAL WITH SUPERIOR THERMAL PERFORMANCE

摘要

A stationary mating ring for a mechanical seal is provided, comprising an annular body having a central axis and a sealing face; a first circumferential groove formed into the body behind the sealing face; and a first annular fin extending radially from the central axis. The mating ring further may include a second circumferential groove formed in the body adjacent to the first circumferential groove, wherein the second circumferential groove defines a second annular fin extending radially from the central axis. Optionally, the first or second annular fins each include a plurality of subdivided fins extending radially from the central axis, and such fins are symmetrically spaced around the central axis. Also provided is a complete mechanical seal, comprising a rotating ring having a sliding interface against a mating ring constructed in accordance with the aforementioned features.
