CYLINDRICAL LINEAR INDUCTION PUMP Russian patent published in 2022 - IPC H02K44/06 H02K1/14 

FIELD: electrical engineering.

SUBSTANCE: cylindrical linear induction pump comprises a cylindrical pump housing, inductors with magnetic conductors of inductors and inductance coils linearly located along the surface of the pump housing. Besides, it comprises core arranged coaxially inside said case to make circular working channel with core magnetic conductors arranged inside case of its central cylindrical part. Magnetic cores of the inductors are made in the form of sets of E-like parallel plates of alternating height of electrotechnical steel. Core magnetic conductors are made in the form of sets of longitudinal plates from electrical steel of variable height, located in longitudinal sectors, formed by a bearing cross with longitudinal ribs installed inside the core along its axis. Orientation of the plates of the mixture of the magnetic conductors of the inductors coincides with the orientation of the plates of the mixture of the corresponding magnetic conductors of the core inside the casing of the central cylindrical part of the core.

EFFECT: increased efficiency and reliability of pump operation by reduction of its power consumption, increased head and flow rate of pumped liquid molten metal at simultaneous increase of its strength, reliability and durability of functioning.
