Description
Bei Pumpen wird üblicherweise das zu fördernde, d.h. zu pumpende, Medium direkt als Kühlmittel für den Antriebsmotor der Pumpe verwendet. Das kann bei Abwasser oder anderen verschmutzten Flüssigkeiten zu einem Verstopfen des Kühlvolumens des Antriebsmotors führen. Des weiteren sind Pumpen, insbesondere Abwasser-Pumpen, mit einem internen Kühlsystem ihres Antriebsmotors bekannt. Dort erfolgt die Umwälzung des Kühlmittels mit Hilfe eines zusätzlichen kleinen Kühlmittel-Laufrades. Dieses Kühlmittel-Laufrad kann mit einem eigenen kleinen Elektromotor wirkverbunden sein. Eine andere Möglichkeit besteht darin, das besagte kleine Kühlmittel-Laufrad direkt mit dem Pumpen-Antriebsmotor anzutreiben. Hierbei ist das Kühlmittel-Laufrad entweder am freien Wellenende der Antriebswelle des Antriebsmotors, dem Pumpenlaufrad zugeordnet, vorgesehen, oder die Antriebswelle des Antriebsmotors ist auf der ihrem freien Wellenende abgewandten Seite verlängert und das Kühlmittel-Laufrad ist auf der vom Pumpen-Laufrad abgewandten Seite des Antriebsmotors vorgesehen. Unabhängig von der jeweiligen Anordnung des Kühlmittel-Laufrades ist es bei diesen bekannten Pumpen erforderlich, den Kühlmittel-Kreislauf mit Hilfe dynamischer Dichtungen zum Antriebsmotor und ggf. zum Fördermedium, d.h. Abwasser, hin abzudichten. Dynamische Dichtungen unterliegen jedoch einer nicht zuverlässig auszuschliessenden Leckage. Eine solche Leckage resultiert beispielsweise in der Gefahr, dass das Kühlsystem im Extremfall ausfällt oder dass Kühlmittel in den Antriebsmotor eindringt.In pumps, usually the one to be pumped, i. to be pumped, medium used directly as a coolant for the drive motor of the pump. This can lead to clogging of the cooling volume of the drive motor in wastewater or other polluted liquids. Furthermore, pumps, especially sewage pumps, are known with an internal cooling system of their drive motor. There, the circulation of the coolant takes place with the help of an additional small coolant impeller. This coolant impeller can be operatively connected to its own small electric motor. Another possibility is to drive said small coolant impeller directly with the pump drive motor. Here, the coolant impeller is either at the free shaft end of the drive shaft of the drive motor, the pump impeller provided, or the drive shaft of the drive motor is extended on the side facing away from the free shaft end and the coolant impeller is on the side facing away from the pump impeller of the Drive motor provided. Regardless of the particular arrangement of the coolant impeller, it is necessary in these known pumps, the coolant circuit by means of dynamic seals to the drive motor and possibly to the pumped medium, i. Wastewater to seal off. However, dynamic seals are subject to leakage that can not be reliably excluded. Such leakage results, for example, in the risk that the cooling system fails in extreme cases or that coolant penetrates into the drive motor.

Der Erfindung liegt die Aufgabe zugrunde, einen Antriebsmotor insbesondere für eine Pumpe zu schaffen, der ein internes Kühlsystem aufweist, das statisch hermetisch abgedichtet ist.The invention has for its object to provide a drive motor, in particular for a pump having an internal cooling system, which is statically hermetically sealed.
Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Anspruches 1 gelöst. Bevorzugte Aus- bzw. Weiterbildungen des erfindungsgemässen Antriebsmotors sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features of claim 1. Preferred embodiments or further developments of the drive motor according to the invention are characterized in the subclaims.
Der erfindungsgemässe Antriebsmotor weist den Vorteil auf, dass er mit dem zu fördernden Medium, wie einem Abwasser oder einer anderen verschmutzten Flüssigkeit, nicht direkt in Berührung kommt, so dass die Gefahr eines Verstopfens des Kühlsystems des Antriebsmotors eliminiert ist. Ein weiterer, ganz erheblicher Vorteil besteht darin, dass dynamische Dichtungen vermieden werden, so dass entsprechende Leckagen zuverlässig ausgeschlossen sind. Bei dem erfindungsgemässen Antriebsmotor dient die Permanentmagnet-Kupplung nicht zur Kopplung der Antriebswelle des Antriebsmotors mit dem Pumpen-Laufrad, sondern zur Kopplung der Antriebswelle des Antriebsmotors mit dem Kühlmittel-Laufrad des hermetisch abgedichteten Kühlsystems des elektrischen Antriebsmotors.The drive motor according to the invention has the advantage that it does not come into direct contact with the medium to be conveyed, such as a wastewater or other polluted liquid, so that the risk of clogging of the cooling system of the drive motor is eliminated. Another, whole considerable advantage is that dynamic seals are avoided, so that corresponding leaks are reliably excluded. In the inventive drive motor, the permanent magnet coupling is not used for coupling the drive shaft of the drive motor with the pump impeller, but for coupling the drive shaft of the drive motor with the coolant impeller of the hermetically sealed cooling system of the electric drive motor.
Das erfindungsgemässe Kühlsystem kann nicht nur bei Pumpen, insbesondere Abwasser-Pumpen, zur Anwendung gelangen, sondern bei jedem beliebigen elektrischen Antriebsmotor mit hermetisch dichtem Kühlsystem. An der Antriebswelle des elektrischen Antriebsmotors kann anstelle eines Pumpen-Laufrades also auch eine beliebiges anderes an sich bekanntes Maschinenelement wie eine Riemenscheibe, eine Keilriemenscheibe, eine Zahnriemenscheibe, od. dgl. anbringbar oder vorgesehen sein.The cooling system according to the invention can be used not only in pumps, in particular wastewater pumps, but in any electric drive motor with a hermetically sealed cooling system. On the drive shaft of the electric drive motor, therefore, instead of a pump impeller, any other known machine element such as a pulley, a V-belt pulley, a toothed belt pulley, or the like can be attached or provided.
Weitere Einzelheiten, Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung von in der Zeichnung dargestellten Ausführungsbeispielen eines erfindungsgemässen Antriebsmotors für eine Pumpe, insbesondere Abwasser-Pumpe.Further details, features and advantages will become apparent from the following description of exemplary embodiments illustrated in the drawing of an inventive drive motor for a pump, in particular wastewater pump.
