 EMI1.1 
 



   Die Erfindung bezieht sich auf solche Schleuderpumpen zum Verdichten   vun   Luft oder anderen Gasen, die unter Mitwirkung einer   Hilfsflüssigkeit   arbeiten. Um das Vermögen der das zu verdichtende Gas mitnehmenden Flüssigkeitsschichte zu   erhöhen,   muss sie eine möglichst grosse Oberfläche erhalten, und das wird nach der Erfindung dadurch erreicht. dass man jeder Schaufel der Pumpe am Umfange eine konkav krummlinige Begrenzung gibt. so dass die weggeschleuderten Flüssigkeitsschichten statt der ebenen Form. die sie bei bekannten Pumpen dieser Art haben, eine gekrümmte Form erhalten. 



   In der Zeichnung ist beispielsweise eine   Ausführungsform   des Erfindungsgegenstandes dargestellt. Fig.   I   ist ein lotrechter Schnitt   des-1, reisenden Schaufelrades   der Pumpe und der dieses umgebenden Teile, und Fig. 2 stellt einen Schnitt nach der Linie   II   in Fig. i dar. 



   A ist die Ansaugleitung für die   Hilfsflüssigkeit   und B das Schaufelrad der Pumpe, das 
 EMI1.2 
 Gas   führt,   steht durch die Wanddurchbrechungen F mit dem Raume D, in den durch das Schaufelrad B die Wasserschichten geschleudert werden ; in Verbindung. Die Schaufeln C des Schaufelrades B, die in Fig. 2 im Schnitt ersichtlich sind, erhalten nach der Erfindung am Umfange eine konkav gekrümmte Randbegrenzung TV, so dass die aus den Kanälen zwischen je zwei Schaufeln 
 EMI1.3 
 erhalten. Die Menge Luft, die durch die Kanäle   Fangesaugt wird, hängt   von   dem Ausmass   der Reibungsflächen ab, die die aus dem Schaufelrad austretenden Flüssigkeitsschichten darbieten. 



  Die der Umfangsrandbegrenzung der Schaufeln des Schaufelrades gegebene besondere Form hat zur Folge, dass Flüssigkeitsschichten von gekrümmter Querschnittsform gebildet werden und dadurch   das Ausmass   der reibenden Flächen und infolgedessen die Leistungsfähigkeit der Pumpe vergrössert wird.

 EMI1.1
 



   The invention relates to such centrifugal pumps for compressing air or other gases which work with the assistance of an auxiliary liquid. In order to increase the capacity of the liquid layer entraining the gas to be compressed, it must have the largest possible surface area, and this is achieved according to the invention. that each blade of the pump is given a concave curvilinear boundary on the circumference. so that the flung away liquid layers instead of the flat shape. which they have in known pumps of this type are given a curved shape.



   In the drawing, for example, an embodiment of the subject matter of the invention is shown. Fig. I is a vertical section of the-1, traveling impeller of the pump and the parts surrounding it, and Fig. 2 shows a section along the line II in Fig. I.



   A is the suction line for the auxiliary liquid and B the impeller of the pump, the
 EMI1.2
 Gas leads, is through the wall openings F with the space D, into which the water layers are thrown by the paddle wheel B; in connection. According to the invention, the blades C of the blade wheel B, which can be seen in section in FIG. 2, are provided with a concavely curved edge delimitation TV so that the out of the channels between two blades
 EMI1.3
 receive. The amount of air that is sucked in through the channels depends on the extent of the friction surfaces presented by the liquid layers emerging from the paddle wheel.



  The particular shape given to the peripheral edge delimitation of the blades of the impeller has the consequence that liquid layers with a curved cross-sectional shape are formed and thereby the extent of the rubbing surfaces and consequently the performance of the pump are increased.
