Abstract

Gegenstand der Erfindung ist eine Spaltrohrmotorpumpe mit einer dem Rotorraum (15) des Motors (2) vorgeschalteten Einrichtung zur Verhinderung eines Übertritts von in der Förderflüssigkeit enthaltenen Feststoffen und einem Flüssigkeitskreislauf zur Kühlung der im Rotorraum (15) vorhandenen Flüssigkeit.
Ein Schutz gegen das Eindringen von Schmutzpartikeln in den Rotorraum (15) und gegen Anreicherungen von Schmutz in dem vor dem Rotorraum (15) gelegenen Gehäusebereich sowie eine ausreichende Kühlung der im Rotorraum (15) befindlichen Flüssigkeit wird erfindungsgemäß durch die Kombination folgender Merkmale erreicht:
a) vor dem Übertritt des Radseitenraums (16) der Pumpe (1) in den Motorbereich (2) ist eine auf der Welle (6) der Spaltrohrmotorpumpe befestigte Schleuderscheibe (19;26) angeordnet;
b) die Schleuderscheibe (19;26) ist umgeben von einem Raum (21), der sich zur Pumpenseite hin konisch erweitert;
c) die Schleuderscheibe (19;26) bildet einen Axialspalt (22) mit einem zwischen Pumpenteil (1) und Motorteil (2) angeordneten Gehäuseteil (9);
d) über einen außerhalb des Motors (2) angeordneten Wärmeaustauscher (3) wird die im Rotorraum (15) vorhandene Flüssigkeit in einem Kreislauf geführt (Fig. 1).
