Title:
SEAWATER PUMP
Document Type and Number:
Japanese Patent JPH01268450
Kind Code:
A
Abstract:

PURPOSE: To omit a movable part and to facilitate maintenance by arranging a pair of electrode plates and a superconductive magnet within an underwater cylindrical conduit to form a pump.

CONSTITUTION: A pair of flat electrode plates 1 are arranged so as to face in parallel and connected with DC power 3 via lead wires 2. Also, a magnetic field generating means 4 generating said magnetic field in the direction perpendicular to both electrode plates 1 is arranged between said electrode plates 1. Said generating means 4 is composed of a superconducting coil 5 and an apparatus for passing the electric current of said coil 5. Further, respective parts arranged in said given positional relation are inserted into a cylindrical conduit 8. In this case, both end openings of the conduit 8 are positioned in the direction perpendicular to both of the line connecting the both electrode plates 1 (direction of electric field) and the longitudinal direction of the winding shaft (direction of the magnetic field) of superconducting coil. Thus, when electric current flows through said pair of electrode plates 1, it is possible to send the seawater into the conduit.
