Description

Mehrstufige Schleuderpumpe.
EMI1.1
achsialen Scheidewände, die die Ein- und Ausströmungskanäle in einzelne Kammern trennen, sind der Erfindung gemäss derart angeordnet und von solcher Dicke, dass jeder Schaufelkanal dos Laufrades beim Übergang in eine andere Stufe vorübergehend an beiden Seiten ganz oder doch zum grösseren Teil verschlossen wird. Dadurch so ! ! das Überströmen von Flüssigkeit bei den Scheidewänden von einer Kammer in eine andere vermindert werden.
Um jedoch die radiale Bewegung der Flüssigkeit in den Schaufelradkanälen beim Übergang in eine andere Stufe nicht vollständig zu vernichten und dadurch grössere Verluste zu verursachen, ist es besonders bei kleinem, radialem Spielraum vorteilhaft, die Schaufelrad- kanäle nicht völlig zu verschliessen, sondern zu beiden Seiten vorübergechend nur bis auf einen kleinen Bruchteil.
EMI1.2
Laufrades rotiert.
Die einzelnen Stufen werden gebildet durch achsial gerichtete Scheide- wände c und d des Gehausos, die so angeordnet und so dick sind, dass jeder Schaufel- kanal des Laufrades beim Übergang in eine andere Stufe momentan zu beiden Seiten gan

verbunden bis zur Ausströmungskammer i, die an die Druckleitung angeschlossen ist.
Die Richtung, in der die Kammern verbunden werden, ist ohne Einfluss auf die Drehriehtung des Laufrades.
Infolge des ungleichen Druckes in den einzelnen Stufen wirkt auf die Laufradachse

Multi-stage centrifugal pump.
EMI1.1
Axial partitions, which separate the inflow and outflow channels into individual chambers, are arranged according to the invention and of such a thickness that each blade channel dos impeller is temporarily closed on both sides at the transition to another stage or at least for the most part. Thereby so! ! the overflow of fluid at the septum from one chamber to another can be reduced.
However, in order not to completely destroy the radial movement of the liquid in the impeller channels during the transition to another stage and thereby cause greater losses, it is advantageous, especially with little radial clearance, not to completely close the impeller channels, but on both sides temporarily only except for a small fraction.
EMI1.2
Impeller rotates.
The individual stages are formed by axially directed partition walls c and d of the housing, which are so arranged and so thick that each blade channel of the impeller momentarily moves to both sides when transitioning to another stage
EMI1.3
connected to the outflow chamber i, which is connected to the pressure line.
The direction in which the chambers are connected has no influence on the direction of rotation of the impeller.
As a result of the unequal pressure in the individual stages acts on the impeller axle
