Title:
INDUCTION TYPE ELECTROMAGNETIC PUMP
Document Type and Number:
Japanese Patent JPH04236162
Kind Code:
A
Abstract:

PURPOSE: To obtain an induction type electromagnetic pump, in which pump efficiency is improved through reduction of induced current in a duct, by composing the duct placed in a traveling field of a nonmagnetic material having low equivalent electric conductivity.

CONSTITUTION: In a sodium flow path 2, traveling field produced in an outer core 3, a slot coil 1 and an inner core 4 produces driving force. At that time, currents are also induced in inner and outer ducts 6, 5 held between the inner and outer cores 4, 3. Effective scheme for reducing the resistance loss of the duct is to reduce the currents to be induced in the ducts 5, 6. Electric resistance of the duct can be increased by employing a high electric resistance material or by employing a high stiffness material and making the duct thin thereby increasing the equivalent electric resistance.
