Patent JP-H08151994-A (JP)
Title: Pump
Inventor: YANO YOSHIO
IPC: F04D13/02
Filed: 1994-11-28
Abstract: PURPOSE: To eliminate a failure in a bearing which is the greatest cause of magnet pump failure, by rotating an impeller while floated in a liquid in a free condition with no contact with the periphery, so as to eliminate a bearing in the liquid. CONSTITUTION: A suction hole is drilled in the center of an impeller 11, and this suction hole communication with a pumping passage in the impeller 11. In a rear surface side of the impeller 11, outer/inner rotors 12, 13, formed of non-magnetic good conductive material, are concentrically fixed to the impeller 11. The outer/inner rotors 12, 13 are formed so as to be capable of rotating respectively outside an outer cylinder and inside an inner cylinder of a can 16 with a slight clearance. That is, the impeller 11 is floated in a liquid in a free condition without having a drive shaft and a bearing so as to rotate in a stable condition. In this way, during operation, a rotary part can be held in no contact with the periphery. Erroneous stepping is eliminated between a drive side and a driven side.  Since a defect of the conventional magnet pump can be thus covered, an operation without a failure can be attained.
