Description
Die Erfindung bezieht sich auf eine elektrisch betriebene Pumpvorridhtung, bestehend aus Motor und Propeller oder Kreiselpumpenlaufrad und Steigerohr sowie aus einer Einrichtung zum Aufrühren der Fltissigkeit und der Sinkstoffe, so daß sie pumpfähig werden, und zur Erzielung einer größeren Pumpleistung durch Zuleiten des Flüssigkeitsstromes beim Pumpen. The invention relates to an electrically operated pump device, consisting of motor and propeller or centrifugal pump impeller and riser pipe as well from a device for agitating the liquid and the suspended matter so that they can be pumped, and to achieve a greater pump capacity by supplying them of the liquid flow when pumping.
Bekannte Pumpen leiten den geförderten Flüssigkeitsstrom nieht in das Steigerohr, sondern durch eine Offnung wieder aus dem Gehäuse heraus, wodurch der Flüssigkeitsstrabl ein Aufrühren der zu pumpenden Flüssigkeit und der Sinkstoffe bewirkt. Known pumps do not lead the liquid flow into the riser pipe, but through an opening back out of the housing, whereby the liquid flow stirs up the liquid to be pumped and the suspended matter causes.
Bei Propellerpumpen erzeugt die Drehung des Propellers Wirbel, die die Flüssigkeit und die Sinkstoffe aufrühren. In propeller pumps, the rotation of the propeller creates vortices, which stir up the liquid and the suspended matter.
Ebenfalls bekannt sind die Leitschaufeln zwecks Zuleitung der Flüssigkeit beim Pumpvorgang. The guide vanes for the purpose of supplying the liquid are also known during the pumping process.
Die Erfindung betrifft nun eine elektrisch betrieszene Pumpvorrichtung mit einer von der Drehrichtung abhängigen Umschaltvorrichtung von Fördern auf Ruhen und umgekehrt. The invention now relates to an electrically operated pumping device with a switching device depending on the direction of rotation from conveying to resting and vice versa.
Abl>. 1 zeigt eine Gesamtansicht der Pumpvorrichtung, Al)b. 2 und 3 jeweils eine besondere Stellung der Umsc!haltvorrichtung. Lead>. 1 shows an overall view of the pumping device, Al) b. 2 and 3 each have a special position of the reversing device.
Bei Linkslauf wird eine Hülse 3 mit Schaufeln 1 voll einem Mitnehmer 4 (Verzahnung oder Stift) aln Antriebswellenende 2 der Pumpvorrichtung 9 mitgenommen, wodurch die zu pumpende Flnssigkeit mit Sinkstoffen im größeren Umkreis aufgekühlt wird (Abb. 2). With counterclockwise rotation, a sleeve 3 with blades 1 is full of a driver 4 (toothing or pin) taken along at the drive shaft end 2 of the pumping device 9, as a result, the liquid to be pumped is cooled with suspended matter in the larger area becomes (Fig. 2).
Dagegen löst sich beim Rechtslauf (Abb. 3) die Hülse 2 vom Mitnehmer 4, worauf sie durch den Flüssiglkeitsstrom 5, der in das Steigerohr 6 gedrückt wird, auf dem Antriehswellenende 2 aufwärts gesogen und mittels der Schaufeln I in einer Arretierung7 am unteren Teil des Steigerohres 6 oder eines Aufstellbügels 8 festgehalten wird, so daß die Schaufeln I nunmehr die Flüssigkeit der Pumpvorriclhtung g zuleiten. ffierdurch wird Wirbelbildung vermieden und dadurch größere Förderleistung erzielt. On the other hand, when running clockwise (Fig. 3), the sleeve 2 detaches from the driver 4, whereupon by the liquid flow 5, which is pressed into the riser pipe 6, on the drive shaft end 2 sucked up and by means of the blades I in one Locking 7 on the lower part of the riser pipe 6 or a mounting bracket 8 held so that the blades I now feed the liquid to the pump device g. This avoids the formation of eddies and thereby achieves a higher delivery rate.
