Description

Kreiselpumpe bzw. Kreiselverdichter ohne Wellendurchtrittsöffnung Die Erfindung bezieht sich auf Kreiselpumpen, Kreiselverdichter od. dgl. Sie bezweckt besonders die weitere Ausbildung solcher Pumpen und Verdichter, bei denen der Läufer zur Vermeidung einer Wellendurchtrittsöffnung indirekt von außen durch Permanentmagnete angetrieben wird.Centrifugal pump or centrifugal compressor without shaft opening The invention relates to centrifugal pumps, centrifugal compressors or the like. It aims especially the further training of such pumps and compressors, in which the rotor to avoid a shaft passage opening indirectly from the outside by permanent magnets is driven.

Bei bekannten Pumpen dieser Art wirken die Magnete auf einen mit dem Förderrad verbundenen aber getrennt von diesem gebildeten :Magnetkörper. Diese Pumpen bedingen einen großen Materialaufwand und haben einen schlechten Wirkungsgrad, weil dem Kraftbedarf der Pumpe noch die Flüssigkeitsreibung des Magnetkörpers zuzurechnen ist.In known pumps of this type, the magnets act on one with the Conveyor wheel connected but formed separately from this: Magnetic body. These pumps require a large amount of material and have a poor level of efficiency, because add the fluid friction of the magnet body to the power requirement of the pump is.

Besonders diese Nachteile werden durch vorliegende Erfindung behoben.These disadvantages in particular are eliminated by the present invention.

Sie beruht im wesentlichen darauf, daß die Magnete direkt auf die Förderschaufeln wirken, indem die außen um den Pumpenkörper umlaufenden Permanentmagnete in der radialen Ebene des Laufrades angeordnet sind und den Förderschaufeln am äußeren Umfang die größte Masse zugeordnet ist.It is based essentially on the fact that the magnets directly on the Conveyor blades act by the permanent magnets rotating around the outside of the pump body are arranged in the radial plane of the impeller and the conveyor blades on the outer Perimeter is assigned the greatest mass.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Der Kreisel a. ist innerhalb der Pumpe gelagert und wird durch außen um die Pumpe rotierende Magnete b, die in der radialen Ebene des Kreisels angeordnet sind, angetrieben.An exemplary embodiment of the invention is shown in the drawing. The top a. is stored inside the pump and is passed around the outside of the pump rotating magnets b, which are arranged in the radial plane of the gyroscope, driven.

Bei der gezeichneten Ausführung, bei der die Pumpenteile aus unmagnetischen Baustoffen - aus austenitischen Edelstählen - bestehen sollen, sind in den Schaufeln magnetische Kerne c. auf die die umlaufenden Magnete b wirken, angeordnet.In the version shown, in which the pump parts are made of non-magnetic Building materials - supposed to consist of austenitic stainless steels - are in the shovels magnetic cores c. on which the rotating magnets b act, arranged.
