The invention relates to a submersible motor-driven pump with an electric drive motor 1 whose perpendicular shaft 2 projects with its bottom end into the pump housing 3 and carries the pump impeller 11 there, the motor housing 15 being made of high-grade steel and the pump housing 3 being made of plastic. <IMAGE>

Description

Die Erfindung betrifft eine Tauchmotorpumpe mit einem elektrischen Antriebsmotor, dessen senkrechte Welle mit ihrem unteren Ende in das Pumpengehäuse hineinragt und dort das Pumpenlaufrad trägt.The invention relates to a submersible pump with a electric drive motor, the vertical shaft of which protrudes into the pump housing at its lower end and there carries the pump impeller.

Tauchmotorpumpen stellen an Festigkeit und Dichtheit höchste Anforderungen. Um diesen Ansprüchen zu genügen, sind Konstruktionen bekannt, die in Herstellung und Montage aufwendig sind.Submersible pumps put on strength and tightness highest requirements. To meet these demands, are known constructions that are in manufacture and Assembly are expensive.

Aufgabe der Erfindung ist es, eine Tauchmotorpumpe der eingangs genannten Art so zu verbessern, daß sie bei einfacher Bauweise und Herstellung höchste Festigkeit, Beständigkeit und Dichtheit besitzt.The object of the invention is a submersible pump type mentioned so that they improve simple construction and manufacture highest strength, Has resistance and tightness.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Motorgehäuse aus Edelstahl und das Pumpengehäuse aus Kunststoff bestehen. This object is achieved in that the stainless steel motor housing and the pump housing Plastic.  

Durch die Wahl von Edelstahl für das Motorgehäuse wird zum einen eine höchste Festigkeit und zum anderen eine hohe Dichtheit und Korrosionsbeständigkeit erreicht. Das Pumpengehäuse ist dagegen aus Kunststoff insbesondere aus Polyurethan und besitzt damit bei hoher Dichtheit, Beständigkeit und Festigkeit zusätzliche eine hohe Verschleißfestigkeit. Ein solches Pumpengehäuse erfordert keine zusätzlichen Stützteile oder Metallversteifungen. Beide Materialien ergänzen einander optimal.By choosing stainless steel for the motor housing on the one hand the highest strength and on the other hand one high tightness and corrosion resistance achieved. The pump housing, however, is made of plastic especially made of polyurethane and therefore has high Tightness, durability and strength additional one high wear resistance. Such a pump housing does not require any additional support parts or Metal stiffeners. Both materials complement each other optimal.

Besonders vorteilhaft ist es hierbei, wenn das Pumpenlaufrad aus Kunststoff insbesondere Polyurethan besteht.It is particularly advantageous here if that Pump impeller made of plastic, especially polyurethane consists.

Die Lagerträger des Motors sind von hoher Präzision und führen die Wärme sehr gut ab, wenn sie aus Aluminium bestehen.The motor bearing supports are of high precision and dissipate the heat very well if it is made of aluminum consist.

Das Motorgehäuse ist besonders preiswert und mit hoher Genauigkeit herstellbar, wenn es durch Fließstrecken erzeugt wird.The motor housing is particularly inexpensive and high Accuracy can be established if it is through flow lines is produced.

Ein besonders sicherer Halt und eine einfache Montage ohne zusätzliche Befestigungsteile wird geschaffen, wenn der Stator des Motors in das Innere des Motors eingedrückt ist. Von größtem Vorteil ist, wenn auf die Außenseite des Motorgehäuses ein koaxialer Kühlmantel befestigt insbesondere aufgedrückt ist, da auch hierdurch Herstellung und Montage vereinfacht werden. Die obengenannten Vorteile gelten darüber hinaus, wenn der Kühlmantel aus Edelstahl besteht.A particularly secure hold and easy assembly without additional fasteners is created if the stator of the motor inside the motor is depressed. The greatest advantage is when on the Outside of the motor housing is a coaxial cooling jacket attached is pressed in particular, as a result of this Manufacturing and assembly can be simplified. The The above advantages also apply if the Cooling jacket made of stainless steel.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einem axialen Schnitt dargestellt und wird im folgenden näher beschrieben. An embodiment of the invention is in the Drawing is shown in an axial section and is described in more detail below.  

Die Tauchmotorpumpe weist einen Elektromotor 1 auf, dessen Welle 2 senkrecht steht und nach unten verlängert ist, um in das Pumpengehäuse 3 einer Kreiselpumpe 4 hineinzureichen. Der Motor 1 weist einen Stator 5 und einen auf der Welle 2 befestigten Rotor 6 auf.The submersible motor pump has an electric motor 1 , the shaft 2 of which is vertical and is extended downward in order to reach into the pump housing 3 of a centrifugal pump 4 . The motor 1 has a stator 5 and a rotor 6 attached to the shaft 2 .

Die Welle 2 ist durch ein oberes und ein unteres Lager 7, 8 gehalten, die in einem oberen Lagerträger 9 und einem unteren Lagerträger 10 befestigt sind. Auf dem unteren Ende der Welle 2 ist das Pumpenlaufrad 11 gelagert.The shaft 2 is held by an upper and a lower bearing 7, 8 , which are fastened in an upper bearing bracket 9 and a lower bearing bracket 10 . The pump impeller 11 is mounted on the lower end of the shaft 2 .

Das elektrische Anschlußkabel 12 des Motors 1 ist über eine Kabelbuchse 13 auf der Oberseite des Motors in dessen Inneres geführt. Ferner ist an der Motoroberseite ein Halter 14 befestigt, um die Tauchmotorpumpe insbesondere durch einen Kran anheben zu können.The electrical connection cable 12 of the motor 1 is guided in the interior of the motor via a cable socket 13 on the top of the motor. Furthermore, a holder 14 is fastened to the upper side of the motor in order to be able to lift the submersible motor pump in particular by means of a crane.

Das Gehäuse 15 des Motors 1 besteht aus Edelstahl und ist durch Fließstrecken hergestellt. Der Stator 5 des Motors wird zusammen mit dem Rotor 6 und den weiteren Motorteilen in das Innere des Gehäuses 15 eingedrückt.The housing 15 of the motor 1 is made of stainless steel and is made by flow lines. The stator 5 of the motor is pressed together with the rotor 6 and the other motor parts into the interior of the housing 15 .

Die Lagerträger 9, 10 sind aus Aluminium gefertigt und können auch durch Eindrücken befestigt sein. Das Motorgehäuse ist außen von einem Kühlmantel 16 koaxial umgeben, so daß der Kühlmantel mit der Außenseite des Motorgehäuses 15 einen Ringraum 17 bildet. Dieser Ringraum 17 ist von einer Kühlflüssigkeit insbesondere Wasser durchflossen, das vom Fördermedium abgezweigt wird. Der Kühlmantel 16 besteht aus Edelstahl und ist durch Aufdrücken auf dem Motor befestigt.The bearing brackets 9 , 10 are made of aluminum and can also be fastened by being pressed in. The outside of the motor housing is coaxially surrounded by a cooling jacket 16 , so that the cooling jacket forms an annular space 17 with the outside of the motor housing 15 . This annular space 17 is flowed through by a cooling liquid, in particular water, which is branched off from the pumped medium. The cooling jacket 16 is made of stainless steel and is attached to the motor by pressing.

Das Pumpengehäuse besteht aus Kunststoff insbesondere aus Polyurethan. In gleicher Weise besteht auch das Pumpenlaufrad 11 aus Kunststoff insbesondere Polyurethan.The pump housing is made of plastic, in particular polyurethane. In the same way, the pump impeller 11 is made of plastic, in particular polyurethane.
