Electromagnetic pump

Abstract

The invention discloses an electromagnetic pump which comprises a pump body. The inner iron core comprises a central cylinder, and the axis of the central cylinder basically coincides with the axis of the electromagnetic pump; the plurality of outer iron cores are at least partially arranged around the inner iron core; the winding is at least partially arranged on the outer iron core; the pump groove mechanism is at least partially arranged between the outer iron core and the inner iron core; the pump groove mechanism comprises a first pump groove wall arranged between the outer iron core and the inner iron core; the second pump groove wall is arranged between the first pump groove wall and the inner iron core; the circulation channel is arranged between the first pump groove wall and the second pump groove wall; the cavity dividing structure is arranged between the first pump groove wall and the second pump groove wall and used for supporting the first pump groove wall and the second pump groove wall; the cavity dividing structure is further used for dividing the circulation channel so that the circulation channel can be divided into a plurality of channels. The pump groove mechanism has the beneficial effects that the cavity dividing structure can block movement of liquid metal moving in the second direction, and therefore circulation of the liquid metal in the pump groove mechanism is reduced.

Description

technical field [0001] The invention relates to the field of electromagnetic pumps, in particular to an induction electromagnetic pump. Background technique [0002] In the prior art, due to the problem of the penetration depth of the magnetic field, an inner iron core is provided to increase the penetration depth of the magnetic field lines, so that the pump groove is completely in the magnetic field, the output of the electromagnetic pump is increased, and the utilization of the electromagnetic pump is improved. efficiency. However, when operating under high frequency conditions, the inner and outer iron cores of the electromagnetic pump will generate circumferential eddy currents, which will cause great eddy current loss and pump body heating, which will affect the flow characteristics of the metal fluid, making the fluid analysis more complicated and more serious. Under the circumstance, the efficiency of the electromagnetic pump will be reduced, the temperature rise wi...

Problems solved by technology

However, the radius of the iron core in the existing electromagnetic pump is relatively large, the amount of manufacturing materials is large, the cost is high, the eddy current loss is obvious, and the solid structure makes the design of the heat dissipation structure more difficult.
