Description

Die Erfindung betrifft ein aus einer Kreiselpumpe und einem diese antreibenden Motor bestehendes, von einem Gehäuse umschlossenes Tauchmotorpumpenaggregat. Solche Aggregate werden zwar meist im untergetauchten Zustand betrieben, so daß die Kühlung ihres Motors durch die das Aggregat umgebende Flüssigkeit erfolgt. In vielen Einsatzfällen ist aber davon auszugehen, daß das Aggregat während einer längeren Betriebsphase so weit aus der Förderflüssigkeit ausgetaucht bleibt, daß der Motor im wesentlichen durch die Umgebungsluft gekühlt würde. Da dies aber meist nicht ausreichend ist, sieht man in solchen Fällen eine ständige Flüssigkeitskühlung vor, die dadurch erreicht wird, daß der Motor von einem zusätzlichen Mantel umschlossen wird, in welchem die von der Kreiselpumpe geförderte Flüssigkeit zum Auslaß des Aggregates geführt wird. Man spricht hier von einer Doppelmantelkühlung.The invention relates to a from a centrifugal pump and a driving this Motor existing submersible pump unit enclosed by a housing. Such units are usually operated submerged, so that the cooling of your engine by the liquid surrounding the unit he follows. In many applications, however, it can be assumed that the unit so far immersed in the fluid during a longer operating phase remains that the engine would be essentially cooled by the ambient air. There but this is usually not sufficient, you can see a constant in such cases Liquid cooling, which is achieved in that the engine by an additional Sheath is enclosed, in which the pumped by the centrifugal pump Liquid is led to the outlet of the unit. One speaks of one here Double jacket cooling.

Nun werden Tauchmotorpumpenaggregate bis dato entweder mit oder ohne eine Doppelmantelkühlung ausgeführt. Dies bedeutet, daß bereits bei der Bestellung einer Tauchmotorpumpe darüber entschieden werden muß, ob das Aggregat mit einer solchen Doppelmantelkühlung ausgestattet und damit vielfältiger einsatzfähig sein soll, oder ob die preisgünstigere Ausführung ohne Doppelmantelkühlung für die zu erwartenden Einsatzfälle ausreichend sein wird. Eine nachträgliche Anderung ist damit nicht möglich. Sollte sich also erst später herausstellen, daß eine Doppelmantelkühlung notwendig wäre, so ist der Betreiber eines Aggregates ohne eine solche Zusatrkühlung gezwungen, ein weiteres Tauchmotorpumpenaggregat anzuschaffen. Der Hersteller von Tauchmotorpumpenaggregaten dagegen muß Aggregate mit und ohne Doppelmantelkühlung parallel fertigen und auf Lager halten. To date, submersible pump units have either been with or without one Double jacket cooling performed. This means that when ordering a submersible pump must decide whether the unit with equipped with such a double jacket cooling and thus more versatile should be, or whether the cheaper version without double jacket cooling for expected use cases will be sufficient. A subsequent change is not possible with it. So should it turn out later that a double jacket cooling would be necessary, the operator of a unit is without one Additional cooling forced to purchase another submersible pump unit. The manufacturer of submersible pump units, however, must have units with and Manufacture in parallel without double jacket cooling and keep in stock.

Der Erfindung liegt die Aufgabe zugrunde, Aggregate der eingangs genannten Art so zu gestalten, daß eine leicht zu bewerkstelligende Umrüstung von der einen auf die andere Form der Kühlung möglich wird.The invention is based, so aggregates of the type mentioned the task to make it easy to convert from one to the other other form of cooling becomes possible.

Dies wird erfindungsgemäß erreicht durch ein aus einer Kreiselpumpe und einem diese antreibenden Motor bestehendes, von einem Gehäuse umschlossenes Tauchmotorpumpenaggregat mit einem wahlweise anbringbaren Kühlmantel, welcher einen mit einer Förderleitung verbindbaren Auslaß besitzt, wobei das die Kreiselpumpe und den Motor umschließende Gehäuse mit Außenflächen versehen ist, an denen Innenflächen des Kühlmantels zur Anlage zu bringen sind, wobei Dichtmittel die zwischen dem Gehäuse und dem Kühlmantel vorhanden Spalte schließen.This is achieved according to the invention by means of a centrifugal pump and a this driving motor existing, enclosed by a housing Submersible pump unit with an optionally attachable cooling jacket, which has an outlet connectable to a delivery line, which is the centrifugal pump and the housing surrounding the motor is provided with outer surfaces, on which inner surfaces of the cooling jacket are to be brought into contact, using sealant close the gaps between the housing and the cooling jacket.

Das erfindungsgemäße Tauchmotorpumpenaggregat geht von einer Basisversion mit einfacher Mantelkühlung aus, die jederzeit durch eine leicht vorzunehmende Änderung, beispielsweise durch das Überstülpen eines Kühlmantels, in eine solche mit Doppelmantelkühlung umgewandelt werden kann. Gegebenenfalls wird der Kühlmantel noch mit einer lösbaren Verbindung, beispielsweise durch Schrauben, an dem die Kreiselpumpe und den Motor umschließenden Gehäuse befestigt.The submersible pump assembly according to the invention is based on a basic version with simple jacket cooling, which can be changed at any time by an easy change, for example by slipping a cooling jacket into one with Double jacket cooling can be converted. If necessary, the cooling jacket still with a detachable connection, for example by screws attached to the housing enclosing the centrifugal pump and the motor.

Das die Kreiselpumpe und den Motor der Basisversion umschließende Gehäuse wird in zweckmäßiger Ausgestaltung der Erfindung mit einer Auslaßöffnung versehen, die nur bei einem ohne Kühlmantel erfolgenden Einsatz einen mit einer Förderleitung zu verbindenden Stutzen erhält.The housing enclosing the centrifugal pump and the motor of the basic version is provided in an expedient embodiment of the invention with an outlet opening, which is only used with a conveyor line when used without a cooling jacket connector to be connected.

Der Umstand, daß der Kühlmantel als separates Teil zu fertigen ist, eröffnet die Möglichkeit, dessen Material, Form oder Farbe an vorgegebene Bedingungen oder an Kundenwünsche anzupassen. The fact that the cooling jacket is to be manufactured as a separate part opens the Possibility of its material, shape or color to specified conditions or to adapt to customer requirements.

Anhand eines Ausführungsbeispiels wird die Erfindung näher erläutert. Die Zeichnung zeigt in

Fig. 1
eine Basisversion des erfindungsgemäßen Tauchmotorpumpenaggregates mit einer einfachen Mantelkühlung in schematischer Darstellung,
Fig. 2
eine um eine Doppelmantelkühlung erweiterte, auf der Version der Fig. 1 basierende Ausführung des erfindungsgemäßen Tauchmotorpumpenaggregates.

Bei einer späteren Aufrüstung auf eine Doppelmantelkühlung kann der Stutzen an seinem Platz verbleiben oder, falls er lösbar angeordnet ist, auch entfernt werden.The submersible pump assembly according to the invention is shown in FIG. 1 Version with simple jacket cooling is used, so at the outlet opening 4 of the housing 1 a nozzle 5 attached to the connection of the unit with a - not shown - conveyor line. With a later upgrade on a double jacket cooling, the nozzle can remain in place or, if it is detachable, also be removed.

Die Fig. 2 zeigt eine auf eine Doppelmantelkühlung aufgerüstete Ausführung. Diese ist durch das Überstülpen eines Kühlmantels 6 zustandegekommen. Der Kühlmantel 6 besitzt Innenflächen, die auf entsprechende Außenflächen an den Teilen 2 und 3 des Gehäuses 1 aufgeschoben werden können. Durch mehrere schraubbare Verbindungen 7 wird der Kühlmantel 6 an dem Gehäuse 1 befestigt. Mit O-Ringen 8 und 9 wird jeweils der zwischen dem Gehäuse 1 und dem Kühlmantel 6 vorhandene Spalt abgedichtet, so daß das von der Kreiselpumpe geförderte Medium das Aggregat ausschließlich über einen an dem Kühlmantel 6 vorgesehenen Stutzen 10 verläßt.2 shows an embodiment upgraded to double jacket cooling. This has come about by putting a cooling jacket 6 on. The cooling jacket 6 has inner surfaces that correspond to corresponding outer surfaces on parts 2 and 3 of the housing 1 can be pushed.
