Background technology
At present, adopt electromagnetic pump for the transmission of liquid metal, electromagnetic pump can be divided into conduction pump and induction electromagnetic pump more, and wherein conduction pump is divided into direct-current electromagnetic pump and single phase alternating current (A.C.) conduction pump again; Induction electromagnetic pump is divided into single-phase induction formula and triphase induction type electromagnetic pump, and wherein the triphase induction type electromagnetic pump comprises plane induction type and two-sided induction type or multiaspect induction electromagnetic pump.There is big, the inefficient problem of volume mostly in existing electromagnetic pump, can not get good solution for a long time.
The utility model content
At the problems referred to above, the utility model proposes a kind of leakage field minimum, most effective, the tangible inside and outside core AC induction pump for transmitting liquid metal of energy-saving effect.
The technical solution of the utility model is: a kind of inside and outside core AC induction pump for transmitting liquid metal, comprise stator core, cake formula Circular Winding, pump ditch pipeline, inner iron core, described stator core is that the multilayer silicon steel sheet is integral by bolted, on stator core, equidistantly have several slots, be equipped with cake formula Circular Winding in each slot, have circular hole on the described stator core direction vertical with the center position of slot, this circular hole and above-mentioned all slot square crossings, in this circular hole, be set with the insulation pipeline, this insulation pipeline passes each cake formula Circular Winding, in insulation pipeline internal sleeve pump ditch pipeline is housed, described inner core length and pump ditch pipeline length coupling, and place pump ditch pipeline center portion.
Described inner iron core is that silicon strip rolls the club shaped structure that forms.
Described inner iron core is connected and fixed by the supporting leg at the iron core two ends pump ditch pipeline inwall outside with it.
Slot on the described stator core is six, evenly distributes.
Described pump ditch pipeline two ends are provided with the reducing contraction section, and are provided with adpting flange in the end of transition contraction section.
The two ends of described insulation pipeline are concordant with stator, and it is neat that described pump line pipe ends is stretched out stator core segment length etc.
The beneficial effects of the utility model
The operation principle of inside and outside core AC induction pump for transmitting liquid metal of the present utility model is similar to linear electric motors, three phase winding pie windings produce travelling-magnetic-field, the molten metal that travelling-magnetic-field penetrates in the pump ditch constitutes field circuit by inner iron core, utilize the interaction of the induced current in magnetic field and the conductor fluid, make fluid be subjected to the electromagnetic force effect and produce barometric gradient, thus the propelling fluid directed movement.
Because electromagnetic pump of the present utility model has special outer stator iron and inner iron core, so have the leakage field minimum, most effective, energy-saving effect is the most obvious.
