Cartridge type mechanical seal connection assembly

Abstract

The invention discloses a cartridge type mechanical seal connection assembly, which comprises a shaft sleeve. The outer of the shaft sleeve is provided with a medium moving ring and a medium static ring close to a medium end, and a water sealing static ring and a water sealing moving ring far away from the medium end. A spring frame, a flange and a water sealing static ring seat are arranged between the medium static ring and the water sealing static ring. Springs are embedded between the spring frame and the flange and between the flange and the water sealing static ring seat respectively. The shaft sleeve is also sleeved with a locking ring that restricts the water sealing moving ring from moving axially outwards. The wall of the locking ring is threadedly connected with a locking screwwhose end abuts against the shaft sleeve. The outer wall of the shaft sleeve is provided with an annular positioning groove with a notch attached to the inner wall of the medium moving ring. A clamp ring is embedded in the annular positioning groove. The clamp ring is a metal ring structure with an open end. The groove bottom of the annular positioning groove is provided at least one threaded hole. The threaded holes are threadedly connected with limit screws. The limit screws are embedded in the threaded holes. The cartridge type mechanical seal connection assembly has the characteristics oftight connection and reliable use.

Description

technical field [0001] The invention relates to a mechanical seal structure, more specifically, it relates to a cartridge type mechanical seal connection assembly. Background technique [0002] The mechanical seal is used to connect the reactor and the shaft extending into the reactor body for stirring function, so that the container mouth of the reactor and the shaft are sealed to achieve a good anti-seepage effect. However, due to the various types of media contained in the reaction kettle, including sodium sulfate slurry, it makes the solution contain sulfuric acid and more chloride ions, which makes conventional metal materials easy to corrode and has poor use effects, while parts made of ceramic materials After replacing the metal material parts, the above problems can indeed be avoided, but another problem arises, that is, how to realize the connection between the metal shaft sleeve and the ceramic material seal, and directly use fasteners to lock to the ceramic materi...

However, due to the various types of media contained in the reaction kettle, including sodium sulfate slurry, it makes the solution contain sulfuric acid and more chloride ions, which makes conventional metal materials easy to corrode and has poor use effects, while parts made of ceramic materials After replacing the metal material parts, the above problems can indeed be avoided, but another problem arises, that is, how to realize the connection between the metal shaft sleeve and the ceramic material seal, and directly use fasteners to lock to the ceramic material seal. Fragile, poor overall effect
