Abstract

The invention discloses an improved mechanical seal with an auxiliary system for an aluminum oxide slurry pump. The improved mechanical seal comprises a seal cavity, an atmosphere side seal gland, a medium side seal gland, a shaft end gland and a shaft sleeve, the atmosphere side seal gland is arranged at one end of the seal cavity, and the medium side seal gland is arranged at the other end of the seal cavity; and a sealing assembly body is arranged in the seal cavity and comprises an atmosphere side sealing assembly body, a medium side sealing assembly body and a spring system arranged between the atmosphere side sealing assembly body and the medium side sealing assembly body. The seal of the aluminum oxide slurry pump is improved, and the double-end-face large spring type mechanical seal is adopted, so that the mechanical seal structure is simplified, meanwhile, the sealing effect can be effectively guaranteed, the service life of the mechanical seal is prolonged to a certain extent, and the maintenance cost of the mechanical seal is reduced; and the efficient production of aluminum oxide can be guaranteed, the development of the aluminum oxide industry is promoted, and the development of the mechanical seal is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of mechanical sealing devices, in particular to an improved mechanical seal for an alumina slurry pump with an auxiliary system. Background technique [0002] Alumina is a high-hardness mixture, which is widely used in industry and is also an important chemical raw material. With the gradual increase of production scale, more and more practical industrial production problems will appear, one of which is the mechanical seal problem of alumina slurry pump. [0003] my country's earliest contact with mechanical seals began with the introduction of foreign pump equipment in the oil refining industry. In the 1960s, my country's Mechanical Research Institute officially began to research and develop mechanical seals, and promulgated my country's first mechanical seal standard in 1975. , followed by a second standard in 1978. After the "Sixth Five-Year Plan" and "Seventh Five-Year Plan" scientific and technological...
