Abstract

The pump wheel has wings which are flexible for the direction of rotation of an independent pump impeller. The pump impeller wings are tiltably arranged. The stress in the material of the pump wings is set against the pressure so that that the outline corresponds to a conventional pump impeller. The impeller wings are defined depending upon direction of rotation by a stop in their end position.

Description

Die Erfindung betrifft ein Pumpenrad welches Drehrichtung unabhängig eingesetzt werden kannThe The invention relates to a pump wheel which direction of rotation used independently can be

Die Erfindung ermöglicht eine kostengünstige Motorauswahl für Pumpen, sowie der Auswahl der Gehäuseformen.The Invention allows a cost-effective Motor selection for Pumps, as well as the choice of housing shapes.

Bekannt sind Kreiselpumpen, welche nach dem Zentrifugalprinzip arbeiten. Das Medium wird im Gehäuse mit einem Pumpenrad über die Drehung des Pumpenrades nach außen geschleudert. Dabei entsteht über die Radialbeschleunigung die Pumpwirkung.Known are centrifugal pumps, which operate on the centrifugal principle. The medium is in the housing with a pump over the rotation of the pump wheel is thrown outwards. It arises over the Radial acceleration the pumping action.

Pumpen mit einem optimierten Wirkungsgrad, haben Pumpenräder deren Pumpenflügel spiral geformt sind, um die Strömung im Pumpenrad zu unterstüzen. Den optimalen Wirkungsgrad haben solche Pumpen immer nur jeweils in eine Drehrichtungpump with optimized efficiency, pump wheels have their pump vanes are spiral shaped to the flow in the impeller to assist. The optimum efficiency of such pumps only ever in one direction of rotation

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein in eine Pumpe integriertes Ventil oder einen Schieber zu integrieren, der ohne einen separaten elektrischen Antrieb betrieben werden kann.outgoing From this prior art, the invention is based on the object to integrate a valve or slider integrated into a pump, which can be operated without a separate electric drive.

Die Erfindung beruht auf folgenden Überlegungen:
Pumpen benötigen häufig Laufräder, deren feste Flügel auf die Pumpleistung und vor allem auf die Drehrichtung ausgelegt sind. Ein Pumpenrad, welches für Linkslauf optimiert ist, hat bei der entgegengesetzten Drehrichtung einen ausgesprochen schlechten Wirkungsgrad.The invention is based on the following considerations:
Pumps often require impellers whose fixed blades are designed for the pumping power and above all for the direction of rotation. An impeller, which is optimized for anti-clockwise rotation, has a very poor efficiency in the opposite direction of rotation.

Durch variable Flügel des Pumpenrades erreichen wir einen jeweils auf die Drehrichtung und Drehzahl abgestimmten Wirkungsgrad, der einem Pumpenrad mit festen Flügeln sehr nahe kommt.By variable wings of the impeller, we reach each one in the direction of rotation and speed-matched efficiency, which is a pump with solid wings comes very close.

Im Pumpenrad, bei gedeckten Laufrädern auch im Pumpenraddeckel, ist an der Stelle in welcher die biegsamen, oder schwenkbaren Flügel eingesetzt werden, eine Vertiefung, die der Kontur entspricht, die die festen Flügel in der jeweiligen Drehrichtung und Auslegung der Pumpe begrenzten. Diese Vertiefung findet man der Anzahl der Pumpenflügel entsprechend am Pumpenrad verteilt.in the Impeller, with muted wheels too in the impeller cover, is at the point in which the flexible, or swiveling wings be used, a depression corresponding to the contour, the the solid wings limited in the respective direction of rotation and design of the pump. This depression can be found according to the number of pump blades distributed on the impeller.

Die Variablen Flügel unseres Pumpenrades bestehen aus biegsamen Material, und werden im Pumpenrad nur mit einer Kante befestigt, so daß sich der Flügel um diese eine Kante bewegen kann.The Variable wings our impeller are made of flexible material, and will fixed in the impeller with only one edge, so that the wing can move around this one edge.

Wird die Pumpe betrieben, legen sich die Flügel durch die Kraft der Strömung an die Kontur an, so daß sie die Geometrie der ausgelegten Pumpe annehmen.Becomes operated by the pump, the wings create by the force of the flow the contour so that they assume the geometry of the designed pump.

Bei der Drehung in die Andere Richtung legen sich die Flügel entsprechend an die andere Kontur an, und können dabei sogar unterschiedliche Kennlinien und/oder Charakteristika ermöglichen, da die Konturen unterschiedlich sein können.at Turning in the other direction, the wings lie down accordingly to the other contour, and can even different characteristics and / or characteristics enable, because the contours can be different.
