Description
Elektromotorisch betriebene Ab_wasserkreiselpumpe mit sich vorübergehend weiter öffnendem Kanallaufrad Abwasserkreiselpumpen, deren ein- oder mehrkanälige Förderräder zum Ausschleudern von Unratkörpern veränderliche Austrittsquerschnitte aufweisen, vermögen nicht immer sich so zu öffnen, daß der Unratkörper tatsächlich ausgeschleudert wird. Man hat wohl bei schleudernder Abwasserförderung ins Innere des Förderrades unter Druck stehende Flüssigkeiten eingeführt, die dem Übelstand des Verstopfens abhelfen sollten, was aber nur zur Zerkleinerung von relativ reichen Unratkörpern führt, festen und groben Beimengungen kann diese Einspritzung nicht beikommen. Kreiselmaschinenräder mit beweglichen Schaufelenden, so daß die Austrittsquerschnitte veränderlich sind, sind an sich bekannt, können aber bei Abwasserförderpumpen praktisch keine Anwendung finden.Electrically operated waste water centrifugal pump with itself temporarily Further opening canal impeller for wastewater centrifugal pumps, their single or multi-channel Conveyor wheels for ejecting debris, variable outlet cross-sections have, are not always able to open in such a way that the debris actually is ejected. One has probably with hurling sewage pumping into the interior of the impeller introduced pressurized fluids, which caused the inconvenience the clogging should help, but that is only enough for the shredding of relatively This injection cannot lead to debris, solid and coarse additions get over. Centrifugal machine wheels with movable blade ends, so that the exit cross-sections are variable, are known per se, but can be practical in sewage pumps do not apply.
Diesem Mangel hilft nun die Erfindung dadurch ab, daß an Stelle eines elektrischen Antriebsmotors mit gleichbleibender Drehzahl ein über ein Umschaltgerät polumschaltbarer für eine zweite höhere Drehzahl angeordnet ist, welcher bei Unratfüllung im Kanalrad der Pumpe und somit Nachlassen der Fördermenge durch eine federbelastete Rückschlagklappe über ein Gestänge steuerbar ist, so daß er durch Drehzahlsteigerung die Unratansammlung ausschleudert.This deficiency is now remedied by the invention in that instead of one electric drive motor with constant speed via a switching device Pole-changeable is arranged for a second higher speed, which when filling with garbage in the channel wheel of the pump and thus decrease in the delivery rate due to a spring-loaded Non-return valve is controllable via a linkage, so that it can be increased by increasing the speed throws out the accumulation of rubbish.
Eine weitere Abhilfe kann noch darin erblickt werden, daß an Stelle des elektrischen Antriebsmotors mit gleichbleibender oder polumschaltbarer Drehzahl ein in der Drehzahl regelbarer Antriebsmotor angeordnet ist, wobei die Drehbewegung der Rückschlagklappe über ein Gestänge auf ein elektrisches Gerät derart übertragbar ist, daß bei zunehmender Verstopfung des oder der Laufradkanäle die Drehzahlsteigerung erfolgt, bis nach völligem Freischleudern des Förderrades und öffnen der Klappe die Rückschaltung des Motors auf die normale Drehzahl selbsttätig eintritt.Another remedy can be seen in that in place of the electric drive motor with constant or pole-changing speed a variable speed drive motor is arranged, wherein the rotary movement the non-return valve can be transferred in this way to an electrical device via a linkage is that with increasing clogging of the impeller channel or channels, the increase in speed takes place until after the conveyor wheel has completely spun free and the flap is opened the motor switches back to normal speed automatically.
In der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform veranschaulicht. Der Pumpensatz, gebildet durch eine Kanalradpumpe 1, mittels elastischer Kupplung 12 verbunden mit dem Antriebsmotor 2, steht durch eine Zulaufleitung 3 mit einem Sammelbehälter 6 in Verbindung. Die Ein- und Ausschaltung erfolgt in üblicher Weise beispielsweise durch eine pneumatische Steuerschaltung 7 und 10. Eine Rückschlagklappe 4 in der Druckleitung 5 steht mit einem Polumschaltgerät 9 durch ein Gestänge 8 in Verbindung, so daß bei Verstopfung des Förderrades der Kanalradpumpe 1 die Klappe 4 durch Nachlassen der Förderleistung sich schließt und die Bewegung der Klappenwelle zur Polumschaltung auf die höhere Drehzahl des polumschaltbaren Motors 2 übertragen wird. Eine weitere Verbesserung wird dadurch erzielt, daß an Stelle des polumschaltbaren Motors 2 ein solcher mit stetiger Drehzahlsteigerung verwendet wird, wobei die Klappenfunktion auf ein Drehzahlsteigerungsgerät übertragen wird.In the drawing, the subject matter of the invention is illustrated in an exemplary embodiment. The pump set, formed by a channel impeller pump 1, connected to the drive motor 2 by means of an elastic coupling 12, is connected to a collecting container 6 through an inlet line 3. The switching on and off takes place in the usual way, for example by a pneumatic control circuit 7 and 10. A non-return valve 4 in the pressure line 5 is connected to a pole changing device 9 through a linkage 8, so that if the feed wheel of the channel pump 1 is blocked, the valve 4 through Decrease in the delivery rate closes and the movement of the flap shaft for pole switching is transferred to the higher speed of the pole-changing motor 2. A further improvement is achieved in that instead of the pole-changing motor 2, a motor with a steady increase in speed is used, the flap function being transferred to a speed-increasing device.
