LINEAR CYLINDRICAL INDUCTION PUMP Russian patent published in 1995 - IPC

FIELD: pumping of liquid metals. SUBSTANCE: pump has wound inductor, annular channel formed by inner and outer shells, internal magnetic circuit. The latter is built up of stacks and rests on internal pipe. At ends it is clamped with conical collet bushings provided with as many longitudinal splits as there are stacks. Magnetic circuit has conical surfaces from ends towards center at angle α = arctg D/L, where D is magnetic circuit outer diameter, L is its length. Split portion of conical bushings protrudes beyond magnetic circuit length through up to 5 mm. EFFECT: enlarged functional capabilities. 3 cl, 3 dwg
