The invention relates to a single end face assembly-type mechanical seal device with screw threads. The single end face assembly-type mechanical seal device with the screw threads comprises a shaft body, a machine seal shaft sleeve, a machine seal moving ring, a machine seal static ring, a machine seal pressure cover and a pump cover, the machine seal shaft sleeve sleeves the shaft body, and the machine seal shaft sleeve is linked with the shaft body; the screw threads are arranged on the machine seal shaft sleeve; the pump cover sleeves on the periphery of the machine seal shaft sleeve, and the pump cover is fixedly connected with the front end part of the machine seal pressure cover; the machine seal moving ring and the machine seal static ring all sleeve on the machine seal shaft sleeve, and the machine seal moving ring is embedded in the front end part of the machine seal shaft sleeve; the machine seal static ring is located on the rear side of the machine seal moving ring; and themachine seal pressure cover sleeves on the machine seal shaft sleeve, and the front end part of the machine seal pressure cover is covered on the back end part of the machine seal static ring. Compared with a prior art, the single end face assembly-type mechanical seal device with the screw threads has a sealing function, has the functions of spinning away slurry in a dead angle of the pump coverand a sealing place, preventing slurry particles deposition machine seal from being short of water and burn out, and prolonging the service life of the mechanical seal.
Description
technical field [0001] The invention relates to the technical field of pump body sealing, in particular to a threaded single-end cartridge mechanical seal device. Background technique [0002] existing technologies such as figure 1 As shown, the currently used single-end cartridge mechanical seal has no thread and no reverse thrust, which leads to the formation of a dead angle between the pump cover and the mechanical seal, which is not conducive to slurry circulation, and easily causes particle deposition and water shortage of the mechanical seal to burn out. Contents of the invention [0003] The purpose of the present invention is to provide a threaded single-end cartridge mechanical seal device. The technical problem to be solved is: the dead angle formed between the pump cover and the mechanical seal is not conducive to the circulation of slurry, and it is easy to cause particle deposition and burnout of the mechanical seal due to lack of water. [0004] The technica...
