Embodiment Construction

[0027] The liquid metal electromagnetic pump includes a pump ditch 1 and a control system. There are shrinkage openings at both ends of the pump ditch 1. An electromagnetic drive unit surrounds the pump ditch 1. The electromagnetic drive unit is formed by a first There are six groups of coils 2, 3, 4, 5, 6, and 7 to the sixth coil. The outer wall of the pump ditch 1 is covered with an insulation layer 9. The electromagnetic drive unit surrounds the outside of the insulation layer 9. The connection between the pump ditch 1 and the electromagnetic drive unit There is a gap between them, and the pump ditch 1 can be moved out freely. The first to sixth groups of coils are connected in delta. Each electromagnetic coil is wound by a hollow copper tube, the pump groove 1 vertically passes through the plane of the electromagnetic coil, and the cooling liquid passes through the hollow copper tube. Liquid metal 8 flows in the pump ditch 1 .

Abstract

The invention discloses a liquid metal electromagnetic pump which comprises a pump ditch, an electromagnetic drive unit, a control system and the like. The pump ditch of the electromagnetic pump vertically passes through the electromagnetic drive unit and can freely move out of the electromagnetic drive unit, thus bringing convenience for maintenance. Variable diameter shrinkage ports at the two ends of the pump ditch are welded with interfaces of peripheral equipment; a progressive wave magnetic field generated by a magnetic coil drives a high-temperature liquid metal medium to flow in the pump ditch, and the flow rate of the liquid metal is adjusted by changing the current intensity in the magnetic coil. An insulation layer between the magnetic coil and the pump ditch isolates the high-temperature radiation of the liquid metal, circulating cooling water is led into the hollow magnetic coil to reduce the temperature of the coil, and the comprehensive effect of the two causes the electromagnetic pump to be capable of working in the liquid metal environment with higher temperature. The liquid metal electromagnetic pump is applicable to the transmission and application of liquid metal with the characteristics of high working temperature, strong corrosiveness, easy oxidization, or large specific gravity and the like, and has the advantages of simple and convenient operation, high efficiency, long service life and the like.

Description

technical field [0001] The invention relates to an industrial special pump, in particular to an electromagnetic pump used for transporting liquid metal medium. Background technique [0002] With the rapid development of industrial production and scientific research, the demand for power pumps for liquid metal medium transmission or mixing is increasing day by day, especially in industries such as waste aluminum recycling, quantitative casting, electromagnetic stirring, metal purification, high-temperature metal transmission, and heavy metal transmission. protrude. Electromagnetic pump has many advantages in the field of liquid metal transmission, it has the advantages of easy operation, high efficiency, long life and so on. [0003] At present, the domestic research and development technology of electromagnetic pumps for light metals is relatively mature, mainly including liquid metal transmission, electromagnetic stirring and wave soldering machines and other mechanical in...
