<P>PROBLEM TO BE SOLVED: To provide a vertical type electric pump capable of shortening pump height without generating shaft run-out. <P>SOLUTION: In this vertical type electric pump, a stator 4 is stored in a motor frame 3 erected on upper part of a pump casing 1 via an oil casing 2, outer circumference surface of an anti-load side lead out part of a motor shaft 6 fitted in a center of a rotor 5 inserted in the stator 4 is supported by a bearing 3A on the anti-load side installed on a bracket 3B on an upper surface of a motor frame 3, a load side lead-out part of the motor shaft 6 is led down in a pump casing 1 and an impeller 7 is installed on a led down tip part 6a thereof. A rolling bearing 9 on load side is provided near a lower end part of insertion surfaces of the rotor 5 and the stator 4, and the rotor 5 is rotatably supported in the stator 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
