Abstract
A novel water cooling structure of a magnetic fluid sealing device comprises a coaxial shell, a magnet, annular magnetic poles located on two sides of the magnet, a magnetic transmission shaft, annular grooves, cooling rings and a plurality of seal rings. The annular grooves are formed in parts, located at the annular magnetic poles, of the magnetic transmission shaft. The outer edge of each annular magnetic pole is stepped. The outer edge surfaces of the small end of each step are located on two sides of the magnet. The areas, corresponding to two stepped shaft shoulders, of the coaxial shell are provided with a water inlet and a water outlet. The cooling rings are located on the small-end outer edge surfaces of the annular magnetic poles on two sides of the magnet. The seal rings are disposed on the connecting parts of the cooling rings and the small-end outer edges surfaces. The section, between the two stepped shaft shoulders, of the inner cavity of the coaxial shell is provided with an annular groove. The novel water cooling structure further comprises water-stop plates which are welded and fixed on the cooling rings. The novel water cooling structure has the advantages that by the modification, the water outlet and the water inlet can be distributed at optional angles, high coordination performance with external matched equipment is achieved, and good water cooling effect is achieved.
