Abstract

The invention discloses a double-drive secondary magnetic pump. The double-drive secondary magnetic pump is composed of a first-stage pump force pump (A) and a second-stage magnetic pump (B), whereina first-stage pump cavity (11a) on the right side and a second-stage pump cavity (11b) on the left side are formed in a pump body (1), a cavity (16) communicated with a first-stage liquid outlet (13)and a second-stage liquid inlet (14) is formed in the pump body (1) to form a tandem type magnetic pump, so that the large-flow and high-lift working conditions can be fully met, the high-strength magnetic force lines of a magnetic rotor can be prevented from cutting an isolation sleeve to generate high-strength eddy current heat when a single-stage pump uses a high-power motor, the problems of overheating demagnetization of the magnetic blocks of the inner magnetic rotor and the outer magnetic rotor and the vaporization of the medium in the overheating high-temperature reinforced isolation sleeve are easily caused, so that the use safety and reliability of the magnetic pump are improved, and the manufacturing difficulty and the production cost of a high-power magnetic pump are reduced.

Description

technical field [0001] The invention relates to a magnetic pump, in particular to a dual-drive two-stage magnetic pump. Background technique [0002] The magnetic pump includes a pump body, a pump cover, a pump shaft, a pump shaft sliding bearing device, an impeller installed on the end of the pump shaft in the pump chamber, an inner magnetic rotor installed at the rear end of the pump shaft, and a spacer sleeve that is sealed and fixedly connected with the pump cover. , a drive shaft connecting frame docked and fixedly connected with the pump cover, and an external magnetic rotor fixedly installed on the shaft end of the drive shaft. [0003] The magnetic pump has good sealing performance without leakage and is widely used in the transportation of toxic and harmful media. Under the working conditions of large flow and high head, the magnetic pump often cannot meet the demand due to its power and eddy current heat limitation, and the maximum power of the magnetic pump does ...
