Definitions

  • the load side motor bracket 1-35 has the connecting portion 1-353 that enters the inside of the extending portion 1-26 apart from the extending portion 1-26 of the pump bracket 1-23. It was supposed to be. However, the load-side motor bracket 1-35 may be engaged with the pump bracket 1-23 so that the end surface 1-353a of the connection portion 1-353 contacts the bottom 1-24 of the pump bracket 1-23. The inner peripheral surface of the extending portion 1-26 and the outer peripheral surface of the connecting portion 1-353 may be in contact with each other. In this case, the notch 353b for the lubricating oil 1-27 to move may not be formed on the end surface 1-353a of the connecting portion 1-353.
  • the motor bracket that engages with the motor frame has the connection portion that enters the inside of the extension portion of the pump bracket. And the end surface by the side of the impeller of this connection part contacts a pump bracket.
  • the pump bracket defines a water flow path with the pump casing and contacts the water. For this reason, the heat generated in the rotor and the stator is transmitted to the pump bracket via the motor bracket, and the pump bracket is cooled with water, so that the motor cooling effect can be improved with a simple structure. Further, since the water transferred by the pump flows through the flow path and does not contact the motor bracket, the maintenance frequency of the motor pump can be reduced.

Abstract

L'invention concerne une motopompe permettant d'obtenir un effet de refroidissement de moteur important par le biais d'une structure simple. L'invention concerne également une motopompe permettant de réduire la fréquence de maintenance. La motopompe comprend une roue, un arbre principal, un rotor, un stator, un carter de pompe, un support de pompe, un châssis de moteur, une plaque latérale, un boîtier de roulement et une tige de refroidissement. La roue est conçue pour pouvoir déplacer de l'eau par rotation. L'arbre principal est relié à la roue. Le rotor tourne d'un seul tenant avec l'arbre principal. Le stator est prévu sur le côté circonférence externe du rotor. Le carter de pompe loge la roue. Le support de pompe présente un orifice traversant à travers lequel l'arbre principal pénètre. Le support de pompe est en prise avec le carter de pompe et délimite un canal d'eau avec le carter de pompe. Le châssis de moteur loge le stator. La plaque latérale est prévue sur une partie d'extrémité du châssis de moteur. Dans la motopompe du présent mode de réalisation, la plaque latérale peut être formée d'un seul tenant avec le châssis de moteur, par exemple par coulée. Le boîtier de roulement présente une partie roulement pour supporter l'arbre principal, le boîtier de roulement se mettant en prise avec la plaque latérale et le support de pompe. La tige de refroidissement est montée de manière à pénétrer la plaque latérale et le boîtier de roulement.
