CYLINDRICAL LINEAR INDUCTION PUMP Russian patent published in 1994 - IPC

FIELD: magnetohydrodynamic technology. SUBSTANCE: pump has an outer magnetic core from stacked cores 2 with a three-phase winding, an inner magnetic core, a channel, cooling chambers 9. Chamber 9 is fastened to cores 2 lengthwise at a distance no less than two pole intervals by bolts 10 screwed into trapezoidal ribs 12. When the pump operates the heat flow from the winding and partially from the channel passes through sheets of cores 2 and heat release element 3 to chambers 9 and is removed by a cooling agent. Pressure ribs 13 are welded to side faces of chambers 9. EFFECT: reduced mass and improved reliability. 6 dwg
