Abstract: In order to improve the design efficiency of the electromagnetic pump and solve the difficulties in the electromagnetic design and performance analysis of the electromagnetic pump, In this paper, Comsol multiphysics software is used to check and calculate the electromagnetic design part, coupling the electromagnetic module and the fluid module, and the calculation results are consistent with the results of the sodium loop performance experiment, which proves the reliability of the calculation results. In addition, the key parameters affecting the performance of the electromagnetic pump are calculated and analyzed, and an optimization scheme is put forward. By reducing the tooth width, increasing the thickness of sodium flow channel and reducing the thickness of the inner and outer walls of the pump groove, the length of the pump is reduced, the volume is reduced, and the efficiency is increased. The efficiency after optimization is increased by 110%. -
