  Schleuderpumpe. 
 EMI1.1 
 Fördermittel eigene Geschwindigkeit erzeugt nun an den Stellen d einen Unterdruck, wodurch ein Nachströmen des Fördermittel aus den Räumen a bewirkt werden kann. 



  Dieser'Teil des   Fördermitleis   wird dann von dem das Laufrad verlassenden Fördermittel mit in den Leitapparat gefördert. Diese Wirkung kann man noch dadurch vergrössern, dass man die Laufradschaufeln am Austritte, verdickt und zur   Gleichhaltung   des Austritts-

   PATENT-ANSPRÜCHE : "   
1.

   Schleuderpumpe, dadurch gekennzeichnet, dass die Wände des Laufradgehäuses nahe an das Laufrad herangeführt, über dieses   hinausgeführt   und als Begrenzung der inneren Breite   (bi)   des Leitapparates benutzt werden, ohne dass sich ein radialer Spalt zwischen Laufrad und Leitapparat bildet, so dass das dem Laufrade mit Geschwindigkeit   ent-   strömende Fördermittel bei seiner im Leitapparate notwendigerweise erfolgenden Erweiterung erst in einiger Entfernung vom Laufrade auf die den Leitapparat in seiner inneren Breite   (b,)   begrenzenden Wände trifft und hiebei Räume (d) in der Breite der Laufradwände und des Spaltes   (c)   unbeaufschlagt lässt, wobei infolge seiner Geschwindigkeit in diesen Räumen (d) Unterdruck erzeugt wird, so dass durch den Spalt (c)

   aus den zwischen den Laufrad- und Gehäusewänden befindlichen Räumen (a) dasselbe oder ein anderes Fördermittel angesaugt werden kann.

  Centrifugal pump.
 EMI1.1
 Conveyor's own speed now generates a negative pressure at points d, which can cause the conveyance to flow in from spaces a.



  This part of the conveyor is then conveyed into the diffuser by the conveyor leaving the impeller. This effect can be increased by thickening the impeller blades at the outlet and to keep the outlet

 EMI2.1
   PATENT CLAIMS: "
1.

   Centrifugal pump, characterized in that the walls of the impeller housing are brought close to the impeller, guided beyond it and used to limit the inner width (bi) of the diffuser, without a radial gap between the impeller and the diffuser, so that the impeller Conveying means flowing out at speed, when it is necessarily widened in the guide apparatus, only meets the walls delimiting the guide apparatus in its inner width (b,) at some distance from the impeller, and in this case spaces (d) in the width of the impeller walls and the gap (c ) leaves unaffected, whereby, due to its speed, negative pressure is generated in these spaces (d), so that through the gap (c)

   the same or a different conveying means can be sucked in from the spaces (a) between the impeller and housing walls.

 

Claims (1)

2. Schleuderpumpe nach Anspruch 1, dadurch gekennzeichnet, dass zur Vergrösserung der von dem aus dem Laufrade austretenden Fördermittel unbeaufschlagten Räume die Laufradschaufeln am Austritte verdickt und zur Wahrung des Austrittsquerschnittes am Laufradaussendurchmesser die innere Breite (ba) des Laufrades am Austritte in axialer Richtung vergrössert wird (auf bisa). 2. Centrifugal pump according to claim 1, characterized in that the impeller blades are thickened at the outlet to increase the spaces unaffected by the conveying means exiting the impeller and the inner width (ba) of the impeller at the outlet is increased in the axial direction to maintain the outlet cross-section at the impeller outer diameter (on bisa).
