Example Embodiment

[0057] In order to make those skilled in the art better understand the solutions of the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0058] like figure 1 As shown, an electromagnetic pump 100 includes a pump body 11 , a winding 12 , a plurality of outer iron cores 13 , an inner iron core 14 and a pump groove mechanism 15 . The pump body 11 is formed with a first accommodating space. The winding 12 is at least partially arranged in the first accommodating space, and the winding 12 is at least partly arranged on the outer iron core 13 for delivering current. The plurality of outer iron cores 13 are at least partially disposed in the first accommodating space, and the inner iron cores 14 are also at least partially disposed in the first accommodating space. The plurality of outer iron cores 13 ...

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...
