Water-cooled, vacuum-resistant, ultra-high temperature, anti-pollution magnetic fluid sealing device

Abstract

This utility model relates to a water-cooled, vacuum-resistant, ultra-high temperature, anti-pollution magnetic fluid sealing device, comprising: a rotating shaft with a magnetic fluid tank on it; a hollow housing fitted around the outside of the rotating shaft, with a labyrinth component at the front end and a cover plate at the rear end; a magnetic fluid sealing assembly fitted around the outside of the rotating shaft, its position corresponding to the magnetic fluid tank; an isolation assembly fitted around the outside of the rotating shaft and located on the inner wall of the housing; a dustproof ring fitted around the outside of the rotating shaft and located at the front end of the housing; and an oil seal fitted around the outside of the rotating shaft and located between the housing and the dustproof ring. This utility model, through the use of the dustproof ring and oil seal, completely blocks fine particles from the outside of the rotating bearing, and compensates for wear between the oil seal and the rotating shaft during rotation using the ring spring of the oil seal, extending service life and ensuring reliability throughout the entire service life.
