The invention provides a self-stabilizing flow cylindrical linear induction electromagnetic pump. The external stator of the electromagnetic pump includes at least two sections, the external stator of each section is a split stator, and the two adjacent sections of the external stator are Circumferentially staggered and assembled by positioning chucks to form an integral outer stator with the function of suppressing unstable flow. The integral outer stator can significantly reduce the influence of the uneven circumferential distribution of the axial velocity of the liquid metal on the stability of the flow field, thereby reducing the disturbance of the fluid caused by factors such as non-axial Lorentz force, and playing a role in stabilizing the flow. It greatly improves the flow stability of large-flow pumps under low-flow conditions.
Description
technical field [0001] The invention relates to the technical field of electromagnetic pumps, in particular to a self-stabilizing flow cylindrical linear induction electromagnetic pump. Background technique [0002] Cylindrical linear induction electromagnetic pump (Annular Linear Induction Pump, ALIP) is the ideal pump type for the main cooling circuit and secondary circuit driving pump of the fourth generation liquid metal cooling fast neutron reactor. The wave magnetic field interacts with the induced current in the conductive fluid to generate a Lorentz force along the axial direction of the pump body to push the fluid to flow along the axial direction of the pump. The ALIP electromagnetic pump realizes the directional movement of the liquid metal in a completely closed condition. This driving method has a simple structure, no mechanical movement, no leakage, and can run stably for a long time. The experimental results show that when the large flow ALIP electromagnetic ...
