| As one of the fourth generation reactors,lead cooled fast reactor has good safety and economy,which makes the whole system loop and safety system simple.However,due to the physical and chemical properties of lead bismuth alloy,lead cooled fast reactor has high requirements on the sealing performance of power pump and corrosion resistance of materials.As a device for transporting conductive fluid,the electro-magnetic pump has the advantages of simple structure and reliable operation,which saves the mechanical rotating parts.It is an ideal choice for transporting liquid lead bismuth alloy.This paper mainly focuses on the design and performance of linear induction electromagnetic pump(1)The structure characteristics and operation principle of the electromagnetic pump are described,and an ideal model is established for theoretical analysis.Based on the ideal model,a simulation model is established to analyze the electromagnetic performance of the electromagnetic pump,and to explore the influence of the structural parameters and armature current parameters of the electromagnetic pump(2)For the end effect of electromagnetic pump,the influence of using short-circuit strip on the transverse end effect is discussed.On this basis,the ideal model is modified,and the electromagnetic design method of electromagnetic pump is proposed.The GUI function of MATLAB is used to write the design program(3)When the design target is 0.0015m~3/s and the output pressure is 1MPa,the design scheme is obtained.Using COMSOL to analyze the electromagnetic perfor-mance and hydraulic performance of the design scheme,the average output pressure is 1.0137MPa,and the error is 1.37%,which meets the requirements. |
