Title:
INDUCTION ELECTROMAGNETIC PUMP FOR CONDUCTIVE LIQUID
Document Type and Number:
Japanese Patent JP2013198338
Kind Code:
A
Abstract:

To provide an induction electromagnetic pump for conductive liquid which can achieve smooth transportation of conductive liquid, by reducing energy loss of the conductive liquid at the inlet and outlet of the induction electromagnetic pump for conductive liquid.

The induction electromagnetic pump for conductive liquid has a duct 3 for passing conductive liquid therethrough, and an inductor 5 for generating a moving magnetic field in the duct 3. The number of turns of coils 6, 6, ... of the inductor 5 provided on the end side of a core 1 disposed in the duct 3 for passing conductive liquid therethrough is set smaller than that of coils 6, 6, ... provided in the center of the core 1. AC currents of the same cycle are conducted through the coils 6, 6, ... provided on the end side of the core 1, and the coils 6, 6, ... provided in the center of the core 1.
