Abstract

The invention belongs to the field of nuclear reactors, and particularly relates to a modular electromagnetic pump for transporting liquid metal in the nuclear reactor. The pump comprises a pump gutter assembly and an electromagnetic module, wherein the electromagnetic module is used for providing electromagnetic force; the pump gutter assembly penetrates the center of the electromagnetic module;flanges are arranged at both ends of the electromagnetic module; fixed blocks are arranged at connecting parts of the flanges and the electromagnetic module; and thus, the modular electromagnetic pumpis provided.

Description

technical field [0001] The disclosure belongs to the field of nuclear reactors, in particular to a modular electromagnetic pump for transporting liquid metal in a nuclear reactor. Background technique [0002] The electromagnetic pump is a device that uses the interaction between the magnetic field and the current in the conductive fluid to cause the fluid to generate a pressure gradient under the action of electromagnetic force, thereby pushing the fluid to move. The electromagnetic pump has no mechanical moving parts, has the advantages of simple structure, good sealing, good high temperature tolerance, reliable operation, and does not require shaft seals. It is mainly used for chemically active sodium, potassium, sodium-potassium alloys and toxic heavy metal lead. It can also be used for pumping liquid metals such as mercury and mercury, and can also be used for pumping molten non-ferrous metals in foundry production. [0003] At present, small and medium flow electromag...
