This invention provides a self-fasten machine sealing device. It includes moving ring, stationary ring and sealing compartment. The sealing compartment is assembled at inner side of casing body and muff-coupled with main shaft and casing body. The inner circumference of moving ring is muff-coupled to rotating shaft. The external end of moving ring has shoulder, which outer circumference is muff-coupled to the inner circumference of sealing compartment. The external end face of moving ring is arranged with compressing nut. The internal end face of moving ring firmly attaches to the step end face of rotating shaft. The inner circumference of moving ring internal end is embedded with 0 shaped ring, which firmly attaches to rotating shaft. The stationary ring is movable muff-coupled between the inner circumference of sealing compartment and outer circumference of moving ring. The external end face of sealing compartment has locating pin, which connects to the stationary ring. The outer circumference of stationary ring is embedded with 0 shaped ring, which firmly attaches to the inner circumference of sealing compartment. The ring groove of moving ring and stationary ring are respectively embedded with attached moving, stationary ring friction pairs. This invention is simple and low cost.
Description
technical field [0001] The invention relates to the mechanical sealing technology of the rotating shaft of the equipment, in particular to a self-tightening mechanical sealing device. Background technique [0002] The existing traditional mechanical seal has large structural size, complex structure, high requirements for use and maintenance, low reliability and high price. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and deficiencies of the prior art, and to provide a self-tightening mechanical sealing device with simple structure, small size, high working reliability and low cost. [0004] The purpose of the present invention is achieved through the following technical solutions: the self-tightening mechanical seal device includes a moving ring, a static ring and a sealing chamber, the sealing chamber is fixed on the inner side of the casing, and is respectively sleeved with the rotating shaft and t...
