Abstract:
(EN) [Problem] To provide a fluid transfer system with which it is possible to suppress a deterioration in efficiency. [Solution] A pump system 1 comprises: a pump 3 for transferring a fluid; a motor 4 which is provided with a plurality of windings 41, 42 and which drives the pump 3; a winding switch 6 for switching a state of connection of the plurality of windings 41, 42; an electric power converting unit 5 which supplies electric power to the motor 4 on the basis of a speed command Sp to control the speed of the pump 3; and a control unit 8 which controls the winding switch 6 in such a way as to switch the state of connection of the plurality of windings 41, 42 on the basis of the speed command Sp.
(FR) Le problème décrit par la présente invention est de fournir un système de transfert de fluide au moyen duquel il est possible de supprimer une détérioration de l'efficacité. La solution selon l'invention concerne un système de pompe 1 qui comprend : une pompe 3 permettant de transférer un fluide ; un moteur 4 qui est pourvu d'une pluralité d'enroulements 41, 42 et qui entraîne la pompe 3 ; un commutateur d'enroulements 6 permettant de commuter un état de connexion de la pluralité d'enroulements 41, 42 ; une unité de conversion d'énergie électrique 5 qui fournit de l'énergie électrique au moteur 4 sur la base d'une commande de vitesse Sp en vue de commander la vitesse de la pompe 3 ; et une unité de commande 8 qui commande le commutateur d'enroulements 6 de sorte à commuter l'état de connexion de la pluralité d'enroulements 41, 42 sur la base de la commande de vitesse Sp.
(JA) 【課題】効率の低下を抑制することが可能な流体移送システムを提供する。 【解決手段】ポンプシステム1は、流体を移送するポンプ3と、複数の巻線41,42を備え、ポンプ3を駆動するモータ4と、複数の巻線41,42の接続状態を切り替える巻線切替器6と、速度指令Spに基づいてモータ4に電力を供給してポンプ3の速度を制御する電力変換部5と、速度指令Spに基づいて複数の巻線41,42の接続状態を切り替えるように、巻線切替器6を制御する制御部8とを有する。
