内蒙 内蒙古科技大学硕士学位论文 I III Through calculation and analysis of the structure of the electromagnetic pump parts found that the magnetic poles of logarithmic are even electromagnetic pump can provide higher magnetic induction intensity. Around the pump ditch the outside of the primary core arrangement more closely, the higher the utilization rate of the magnetic field strength on winding. Moreover, center core thickness on primary core yoke thickness is advisable. Reference parts structure on the influence of electromagnetic pump efficiency, when designing electromagnetic pump according to the volume of electromagnetic pump required size determine the bearing capacity of the winding, differential pressure and flow rate for the electromagnetic pump transfers relevant parameters, such as rational design scheme is put forward. In the internal structure and external load, etc, on the basis of the calculation and analysis, this paper successfully create a head of 310 mm, 250 mm diameter of the cylinder induction electromagnetic pump, the pump rated line voltage 120 v, 30 a line current, can provide 0.5 a tm and 17 L/min flow. Through simulation of liquid metal tin, transport within the pump to observe the simulation of a sinusoidal electromagnetic pump cycle liquid tin in the change of the magnetic induction intensity, the induced current and electromagnetic force. The electromagnetic pump transmission head and its corresponding model calculation result is of high consistency. Experiments show that the finite element analysis technology to design for electromagnetic pump provides effective guidance.
