Title
(DE) Heizungsumwälzpumpe für Wechselstrombetrieb und Anlage mit einer solchen Pumpe.
(EN) CENTRAL HEATING CIRCULATION PUMP FOR ALTERNATING CURRENT AND SYSTEM COMPRISING SUCH A PUMP
(FR) Pompe de circulation à courant alternatif pour installation de chauffage central et installation comportant une telle pompe.
Abstract
(EN) A device allows to reduce the power used by the motor of a circulation pump actuated by an electric motor for heating installations. The reduction is obtained by interrupting periodically the network power supply by means of an electronic switch (20, 51-57, 60-68, 122, 123) so that ON and OFF periods follow one after the other. The switch interrupts or resets the current combustion during a zero passage of the voltage, according to a known process.
(FR) Un dispositif permet de réduire la puissance absorbée par le moteur d'une pompe à circulation actionnée par un moteur électrique pour installations de chauffage. La réduction est obtenue en interrompant périodiquement l'alimentation par le réseau par le moyen d'un commutateur électronique (20, 51-57, 60-68, 122, 123) de sorte que des périodes de mise en circuit et de mise hors circuit se succèdent. Le commutateur interrompt ou rétablit la conduction du courant lors du passage par zéro de la tension, selon un procédé déjà connu également.
