The invention relates to a container packaging type mechanical seal for an alkali pump, in particular to the container packaging type mechanical seal for the
corrosion-resistant alkali pump. The container packaging type mechanical seal for the
corrosion-resistant alkali pump comprises a shaft sleeve, a gland, a medium end seal and an
atmosphere end water seal, wherein the medium end seal is located on the inner side of the gland, and the
atmosphere end water seal is located on the outer side of the gland. An
impeller is arranged at the end of a pump shaft through an
impeller hub, the side, close to the
impeller, of the shaft sleeve is provided with a step type structure connected with the shaft sleeve through an inclined face, the side, close to the impeller, of the step type structure isprovided with an annular groove with the opening facing the pump shaft, the step type structure is provided with an axial positioning hole, and the side, away from the impeller, of the shaft sleeve isprovided with a
convex structure and a radial positioning hole. Compared with the prior art, the container packaging type mechanical seal for the
corrosion-resistant alkali pump has the following advantages that the container packaging type mechanical seal can be used for conveying a medium with the medium
solid content being 40% after being installed in the alkali pump, the shaft sleeve structure is reasonably designed, the container packaging type mechanical seal is used for conveying the concentrated alkali medium, the sealing effect is goof, use is safe and
environmentally friendly, the
environmental protection requirements of industrial production are met, the service life is long, the treatment cost of harmful gas is saved, and
economic benefits are remarkable.
