Document Type and Number:
Japanese Patent JP2018053873
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor pump having a simple structure and a high cooling effect on a motor, and provide a motor pump having a low maintenance frequency.SOLUTION: A motor pump comprises an impeller, a main shaft, a rotor, a stator, a pump casing, a pump bracket, a motor frame, a side plate, a bearing housing, and a cooling rod. The main shaft is connected to the impeller, and rotates integrally with the rotor. The stator is provided on the side of an outer periphery of the rotor. The pump casing houses the impeller. The pump bracket comprises a through hole through which the main shaft penetrates, and engages with the pump casing to define a flow path for water. The motor frame houses the stator. The side plate is provided at an end part of the motor frame. The bearing housing comprises a bearing part that bears the main shaft, and engages with the side plate and the pump bracket. The cooling rod is attached so as to penetrate through the side plate and the bearing housing.SELECTED DRAWING: Figure 1
