MAGNETOHYDRODYNAMIC PUMP FOR ELECTRICALLY CONDUCTIVE LIQUIDS Russian patent published in 2023 - IPC F04F99/00 H02K44/02 

FIELD: applied magnetohydrodynamics.

SUBSTANCE: invention is intended for pumping metals and alloys both in metallurgy and in the nuclear industry for pumping liquid metal in cooling systems. Magnetohydrodynamic pump of a traveling magnetic field for electrically conductive liquids, having two rectangular parallel channels made of non-magnetic material, united at their ends by inlet and outlet nozzles, a laminated parallelepiped-shaped ferromagnetic core located between the channels with abutting, two inductors located on the outer sides of the channels, each of which consists of a laminated ferromagnetic core and electric coils placed in its grooves and connected to a three-phase network so as to create a common magnetic flux in the core located between the channels, whereas each inductor core is equipped with its own electric coils covering only its core, and the pump channels are hydraulically interconnected by side pockets with parallel impermeable partitions located at an angle of 90° to the longitudinal axes of the channels. The pockets hydraulically unite the volumes of the pump channels, and the transverse partitions in them prevent the longitudinal flow of liquid metal in them.

EFFECT: simplified access to the pump design elements for preventive maintenance and repair, as well as reduction of the transverse edge effect, which improves its performance.
