Influence of structural parameters on performance of annular linear induction electromagnetic pump
Annular linear induction electromagnetic pump(ALIP)is a key drive device for pumping cool-ant in liquid metal reactors.In the design and analysis of the electromagnetic pump,the structural pa-rameters are important factors affecting the output performance of the electromagnetic pump.In order to further study the influence of the structural design parameters of the annular linear induction electromag-netic pump on its output performance.Firstly,the finite element analysis software was used to establish a simulation model of the annular linear induction electromagnetic pump by considering the effect of the end effect and the influence of the annular conductive pipeline,and then,based on this model,the influence of the different gear ratios,the height of the flow channel and the thickness of the pipeline wall on the e-lectromagnetic pump's magnetism density distribution,the electromagnetic density distribution and the output electromagnetic force was analyzed by calculation.Finally,the output characteristics and efficien-cy of the toroidal linear induction electromagnetic pump with different structural parameters were further compared and analyzed,and the results provide a reference basis for the optimization of the structural pa-rameters of the toroidal linear induction electromagnetic pump.
