Description
Kreiselpumpe mit Umkehr der Strömungsrichtung. Die Erfindung betrifft eine Vorrichtung zur Umkehr der Strömungsrichtung nach Patent 329629, jedoch mit der Abweichung, daß die beiden gegenüberliegenden Schaltklappen durch eine Doppelflügelklappe ersetzt werden. Bei dieser Ausführung mit einer Schaltklappe werden beide Anschlußstutzen nach einer Seite hin angeordnet. -In der Zeichnung ist ein Schnitt durch die Pumpe dargestellt.Centrifugal pump with reversal of the flow direction. The invention relates to a device for reversing the direction of flow according to patent 329629, but with the difference that the two opposite switching flaps are replaced by a double-wing flap. In this version with a switching flap, both connecting pieces are arranged to one side. -The drawing shows a section through the pump.
Die Wirkungsweise der Pumpe nach der Abbildung ist folgende Bei der gezeichneten Stellung der Klappe a tritt die Flüssigkeit durch den Stutzen b und den Kanal c zum Laufrade d; erhält durch dieses die notwendige Energie und tritt durch den Gehäusekanal e und den Stutzen f wieder aus. Der Verlauf der Strömung durch die Pumpe ist in diesem Falle durch ausgezogene Pfeile gekennzeichnet. Wird nun die Schaltklappe a durch den Hebel g um einen bestimmten Winkel gedreht (in Abbildung punktiert gezeichnet), so wird die Strömungsrichtung sich umkehren (Strömungsrichtung wie punktierte Pfeile) ; es wird also in diesem Falle f der Saugstutzen und b der Druckstutzen sein.The mode of operation of the pump according to the figure is as follows Drawn position of the flap a, the liquid passes through the nozzle b and the channel c to the impeller d; receives the necessary energy through this and kicks through the housing channel e and the nozzle f. The course of the current in this case the pump is indicated by solid arrows. Will now the switching flap a is rotated by the lever g through a certain angle (in Figure drawn dotted), the direction of flow will reverse (direction of flow like dotted arrows); So in this case it becomes f the suction nozzle and b the Be pressure port.
