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.
