KLASSE 89: Pumpen.CLASS 89: Pumps.

Den Gegenstand vorliegender Erfindung bildet ein Schaufelrad für Schleuderpumpen, durch welches das in der Mitte infolge der Luftverdünnung zuströmende Wasser _ allmälig zur Seite abgelenkt wird, so dafs "Wirbelungen und Stöfse möglichst vermieden werden.The subject of the present invention is a paddle wheel for centrifugal pumps, through which the water flowing in in the middle as a result of the dilution of the air _ gradually is deflected to the side, so that eddies and bumps are avoided as far as possible.

Auf beiliegender Zeichnung stellt:On the accompanying drawing:

Fig. ι eine mit einem derartigen Schaufelrad versehene Schleuderpumpe dar, während dieFig. Ι a centrifugal pump provided with such a paddle wheel, while the

Fig. 2 den Grundrifs undFig. 2 the Grundrifs and

Fig· 3 die Seitenansicht des Schaufelrades veranschaulicht.Figure 3 illustrates the side view of the paddle wheel.

Das Schaufelrad besteht aus zwei Blechkegeln A und U, zwischen denen die radialen, leicht gekrümmten Schaufeln c befestigt sind. ■ An den Kegel B setzt sich ein Ring b an, welcher dicht an dem Kopfring d des waagrechten Rohres f läuft, das von der das Schaufelrad tragenden, mit entsprechenden Abdichtungen versehenen Welle durchdrungen wird. In das Rohr f mündet das Saugerohr e ein, während das Druckrohr g mit. dem das Schaufelrad umgebenden Gehäuse, in Verbin-. dung steht.The paddle wheel consists of two sheet metal cones A and U, between which the radial, slightly curved blades c are attached. A ring b is attached to the cone B , which runs close to the head ring d of the horizontal pipe f , which is penetrated by the shaft carrying the impeller and provided with appropriate seals. The suction pipe e opens into the pipe f , while the pressure pipe g with it. the housing surrounding the impeller, in connec- tion. dung stands.

Die Schaufeln c setzen sich nun über den Kegel B hinweg fort und gehen in winkelförmig abgebogene , schräg gegen den Ring b stofsende Schaufeln α über. Wird das Schaufelrad in Drehung versetzt und in den Zwischenräumen · zwischen den Schaufeln eine Luftverdünnung erzielt, so wird das Wasser eingesogen und trifft gegen die inneren Schaufeln a, welche etwa unter 30 ° geneigt sind. Dieselben dienen dazu, das Wasser nunmehr zu den sich unmittelbar anschliefsenden Schaufeln c abzuleiten, wodurch ein sehr sanfter und ruhiger Gang der Pumpe erreicht wird.The blades c now continue over the cone B and go into blades α bent at an angle and inclined against the ring b . If the paddle wheel is set in rotation and the air is diluted in the spaces between the paddles, the water is sucked in and hits the inner paddles a, which are inclined at about 30 °. The same serve to divert the water to the immediately adjoining blades c , whereby a very smooth and quiet operation of the pump is achieved.

Patent-Anspruch:Patent claim: Ein Schaufelrad für Schleuderpumpen, bei welchem die zwischen den kegelförmigen Kappen A und B befindlichen Schaufeln c in winkelförmig abgebogene und schräge innere, mit dem Ring b verbundene Schaufeln α übergehen, welche bei der Drehung des Schaufelrades den Eintritt des Wassers in die Zwischenräume der Schaufeln c erleichtern.A paddle wheel for centrifugal pumps, in which the blades c located between the conical caps A and B merge into angularly bent and inclined inner blades α connected to the ring b , which when the paddle wheel rotates the entry of the water into the spaces between the blades c facilitate.
