Problems solved by technology

[0004] The above-mentioned prior art submerged pump has a complex structure, high cost, and difficult assembly and maintenance.
The medium is prone to leakage, that is, the medium will not only produce a certain amount of leakage at the mechanism seal, but also a large amount of medium leakage will occur when the mechanism sealing device is damaged, and there is a danger of a large amount of medium leakage
When the medium to be transported is toxic, flammable, or explosive, a large amount of leakage of the medium during operation will cause a safety accident

Abstract

The invention relates to a magnetic drive submerged pump. The magnetic drive submerged pump is characterized by comprising a pump body (11), a pump cover (12), a pump shaft (13), an impeller (14), a shaft bracket cylinder (2), bearing devices (31 and 32) disposed between the shaft bracket cylinder (2) and the pump shaft (13), a mechanical seal (5), an inner magnetic rotor (15), a spacer (16), an outer magnetic rotor (17), and a connecting rack (18). Bearing block discs (3), a seal gland (4), a rolling bearing (31) and a mechanical seal (5) are fixedly connected between end tubes (2a and 2b). The magnetic drive submerged pump is simple in structure, low in manufacturing cost, simple and convenient to assemble and maintain, good in airtightness and safe to use.

Description

technical field [0001] The present invention relates to submerged pumps, and more particularly to magnetic drive submerged pumps. Background technique [0002] The submerged pump is to immerse the impeller and pump body parts in the conveyed medium. The medium is generally placed in a container or a pit, and the motor drive mechanism is located above the foundation. It is a special vertical pump and is widely used in power plants. , metal smelting, chemical process and sewage treatment and other fields. [0003] The existing submerged pump has a centrifugal submerged pump, and its structure is as attached figure 1 As shown, it includes a pump body, impeller, pump cover, pump shaft, and shaft frame tube. The shaft frame tube can be composed of multi-section butt joint connections, and bearing seat plates and bearings are provided on the butt ends of the two shaft frame tubes. The pump shaft can be It is composed of two or more butt joints. The bearings are ceramic sliding b...
