Description
Die Erfindung betrifft eine Pumpe für die Förderung von Schlamm. Eine solche Förderung bringt verschiedene Schwierigkeiten mit sich, so daß sich die bekannten Unterwasserpumpen normaler Bauart, bei denen eine Kreiselpumpe mit einem über ihre angeordneten, mit wasserfester Wicklung versehenen Elektromotor zu einem Tauchpumpenaggregat vereint ist, nicht ohne weiteres als Schlammförderpumpen eignen. Dies liegt in erster Linie daran, daß der Motor innerhalb der Druckleitung liegt, so daß die Gefahr besteht, daß sich der geförderte Schlamm, welcher den Motor nicht immer genügend kühlt, zwischen diesem und dem Zylinderrnantel der Druckleitung infolge Erwärmung festsetzt und letztere verstopft. Auch wird der Motor insbesondere dann nicht genügend gekühlt, wenn er über Wasser liegt.The invention relates to a pump for pumping sludge. One such promotion brings with it various difficulties, so that the known Submersible pumps of normal design, in which a centrifugal pump with one over their arranged, provided with waterproof winding electric motor to a submersible pump unit is united, are not readily suitable as sludge pumps. This is in the first place Line on the fact that the engine is inside the pressure line, so that there is a risk of that the pumped sludge, which does not always cool the engine sufficiently, between this and the cylinder jacket of the pressure line as a result of heating and the latter clogged. In particular, the engine is not cooled sufficiently, when he is above water.
Die Erfindung bezweckt deshalb eine Verbesserung der oben bezeichneten Tauchpumpenaggregate derart, daß diese ohne jegliche Störungen als Schlammpumpe verwendet werden können. Sie erreicht dies dadurch, daß der Elektromotor in an sich bekannter Weise außerhalb der Pumpendruckleitung angeordnet und in gleichfalls an sich be- kannter Weise so ausgelegt ist, daß er sowohl beim Betrieb im Wasser wie in Luft ausreichend gekühlt ist.The invention therefore aims to improve the above-mentioned submersible pump units in such a way that they can be used as a sludge pump without any malfunctions. It achieves this by the fact that the electric motor is arranged in a known manner outside the pump pressure line and laid out in likewise manner known per se so that it is both sufficiently cooled in air when operating in the water.
Durch die den Motor umgehende Purnpeilleitung wird jegliches Festbacken des Schlammes und durch die entsprechende Auslegung des Motors wird ein Heißlaufen desselben auch dann verhindert, wenn er sich über Wasser befindet.Any sticking is prevented by the pressure gauge line bypassing the motor of the sludge and the appropriate design of the engine will run hot it also prevents it when it is above water.
Die erfindungsgemäße Unterwasser-Schlammpumpe soll in erster Linie als Baugruben-Entwässerungspumpe p Anwendung finden, wie dies in der Zeichnung in Fig. i schematisch dargestellt ist, wobei sie in einfachster Weise in die Baugrube versenkt und auf die Sohle der Grube gestellt wird und über eine Schlauch- oder Rohrleitung t sofort die Wasserförderung aufnehmen kann. Da der Pumpe p das Baugrubenwasser stets zuläuft, wird die meist umständliche und häufig zu Störungen Anlaß gebende Saugleitung, die für über dem Wasserspiegel angeordnete Pumpen notwendig ist, vermieden. Durch die Anordnung der Pumpe p unter dem Motor m ist außerdem gewährleistet, daß die Grube g bis auf den Sumpf entwässert wird.The underwater sludge pump according to the invention is primarily intended to be used as an excavation drainage pump p , as is shown schematically in the drawing in FIG Hose or pipe t can immediately start pumping water. Since the excavation pit water always flows into the pump p, the suction line, which is usually cumbersome and often gives rise to malfunctions and which is necessary for pumps arranged above the water level, is avoided. The arrangement of the pump p under the engine m also ensures that the pit g is drained down to the sump.
Die Pumpe p kann ferner, gemäß Fig. 2- am Seils hängend,- nach Bedarf in eine entsprechende Tiefenlage abgesenkt werden, wie dies bei den üblichen Abtenfpumpen bekannt ist, benötigt jedoch im Gegensatz zu diesen keineÜberwachung gegenüber Überflutung des Motors.P can the pump further, according to FIG 2 the rope hanging, -. Be lowered as required in a corresponding depth location, as is known in the conventional Abtenfpumpen required j edoch in contrast to these no surveillance against flooding of the engine.
Weiterhin kann die Pumpe p, wie bei der gebräuchlichen Anordnung der Unterwasserpumpen gemäß Fig. 3 auch an einer Steigrohrleitung st hängend, in den Schacht b oder in die Baugrube g eingehängt werden.Furthermore, the pump p, as in the customary arrangement of the underwater pumps according to FIG. 3, can also be suspended from a riser pipe st, in the shaft b or in the excavation g .
