Abstract

The invention provides a floating seal ring with a composite working face. The floating seal ring with the composite working face comprises an upper sealing ring body and a lower sealing ring body which are symmetrical in structure. The sealing ring bodies are made of metal materials, a circle of groove for arranging a sealing ring is formed in the outer side of each sealing ring body, a circle of wear-resistant belt assembling groove is formed in the working face of each sealing ring body, the width 12 of the wear-resistant belt assembling groove is 25%-75% of the total width 11 of the working face, a wear-resistant belt is fixedly assembled in the wear-resistant belt assembling groove, the wear-resistant belt is made of aluminum oxide ceramic materials or other engineering ceramic materials, the friction surface of the wear-resistant belt and the working faces of the sealing ring bodies are located on the same plane, or the friction surface of the wear-resistant belt protrudes out of the working faces of the sealing ring bodies. The floating seal ring with the composite working face can effectively improve the wear resistant degree of the working face, prolong the service life, and is easy to machine and low in production cost.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a composite working face floating seal ring used for floating end face seals in mechanical equipment. Background technique [0002] The floating seal ring is applied to the floating end face seal. It is a mechanical seal with a large amount and a wide range of uses (the annual demand in figure 1 As shown, this seal is composed of two metal floating end face seal rings (referred to as floating seal rings) and two "O"-shaped rubber seal rings installed on the central shaft. It has the characteristics of wear resistance, impact resistance, certain adaptability, long life, simple structure, low price, convenient maintenance and replacement, etc. widely used in the sealing structure. Due to the special use environment of the floating seal ring, it is a vulnerable part. The exposed installation position, the skills of installation and debugging personnel, the ambient temperature, the perfor...
