Abstract

PURPOSE: To provide a mechanical seal, in which a seal having a contact surface is made of a sintered alloy impregnated with a thermosetting resin, whereby it is enabled to improve productivity and sealing performance of the mechanical seal, to also improve its slurry resisting performance and strength, and to prolong its service life.
CONSTITUTION: Seal ring 9 is obtained, for instance, by impregnating a sintered alloy of copper, tin and lead with phenol resin. Such a seal ring is advantageous in that there is almost no need of maching so that its productivity is improved, its porosity is low for a product of sintered alloy so that sezling performance can be improved, and in that its strength and slurry resisting performance can be improved. Further, since sealing ring 9 is impregnated with a thermosetting resin at its contact surface S, there are obtained such advantages that surface roughness at the contact surface S is fine, the surface S is protected against slurry so that its slidability is improved, ans that its wear resisting performance is improved.
