Its advantages are high output pressure, high sealing performance, no leakage and compact structure. The electromagnetic pump realizes the shaftless transmission of a pump machine, does not need a sealing shaft, is safe and static sealed, and solves the problems of mechanical transmission and pump shaft leakage. And are therefore commonly used for the delivery of toxic heavy metals, chemically active liquid metals and cast high temperature molten metals.
The induction type cylindrical pump is a main variety of electromagnetic pumps, can be used for conveying high-temperature liquid metal (such as sodium and the like), three-phase windings in a cylindrical iron core have phase difference of 120 degrees, are spatially distributed to form respective magnetic fields, generate a traveling wave magnetic field and generate induced current with the liquid metal sodium in a pump groove, and the liquid metal sodium in the pump groove becomes a current-carrying conductor and generates electromagnetic force to drive sodium solution to directionally flow under the action of the traveling wave magnetic field.
