Description
Geschlossenes Pumpenlaufrad Die vorliegende Erfindung bezieht `sich auf eine Förderpumpe, deren Rotor-als geschlos= senes Laufrad ausgebildet ist. Sie besteht in der besonderen Ausbildung dieses Laufrades in der Weise, daß es in mehrere abwechselnd parallel und senkrecht zur Welle liegende Förderabschnitte unterteilt ist und zwischen dem Laufradmantel und der -Nabe schraubenförmige Schaufeln derart angeordnet sind, daß die Förderflüssigkeit in mehreren Stufen aus der Richtung parallel zur Welle in die Richtung senkrecht zur Welle umgelenkt wird, während sie gleichzeitig-im Schraubengang in den geschlossenen Laufradkanälen von verhältnismäßig großer Länge vorwärts bewegt wird.Closed pump impeller The present invention relates to ` on a feed pump, the rotor of which is designed as a closed impeller. she consists in the special design of this impeller in such a way that it is divided into several Alternately parallel and perpendicular to the shaft lying conveyor sections divided is and between the impeller shell and the hub helical blades such are arranged that the delivery liquid in several stages from the direction parallel is deflected to the shaft in the direction perpendicular to the shaft, while at the same time-im Helical thread in the closed impeller channels of relatively great length is moved forward.
Durch diese eigenartige Ausbildung des Laufrades wird gegenüber den bekannten Pumpen der Vorteil größerer Saugkraft erzielt und ein. Abreißen der Saugleitung verhindert.This peculiar design of the impeller is compared to the known pumps achieved the advantage of greater suction power and a. Tear off the suction line prevented.
In der beiliegenden Zeichnung ist das Laufrad der Förderpumpe bei abgenommener oberer Wand und mit den Schaufelflächen schaubildlich dargestellt.The impeller of the feed pump is shown in the accompanying drawing removed upper wall and shown diagrammatically with the blade surfaces.
Das Laufrad besteht aus dem unteren bzw. inneren Mantel I (der Nabe) und dem oberen bzw. äußeren Mantel 2, der in der Zeichnung nur an einer Stelle dargestellt ist. Zwischen den beiden von dem Saugstutzen ab nach hinten stufenartig ansteigenden Mantelflächen I und 2 sind die Schaufeln 3 angeordnet, die von dem Saugstutzen ab schraubenförmig bis zu dem jeweiligen Austritt ¢ an dem Laufrad verlaufen. Diese Schaufeln bilden schraubenförmig verwundene Kanäle für die zu fördernde Flüssigkeit. Der Querschnitt dieser Leitkanäle vermindert sich in an sich bekannter Weise von dem Saugstutzen bis zum Austritt allmählich, wodurch eine Steigerung der relativen Austrittsgeschwindigkeit gegen--über der relativen Eintrittsgeschwindigkeit der-zu fördernden Flüssigkeit erzielt wird.The impeller consists of the lower or inner shell I (the hub) and the upper or outer shell 2, which is shown in the drawing only at one point is. Between the two that rise in steps towards the rear from the suction nozzle Outer surfaces I and 2, the blades 3 are arranged from the suction nozzle run helically up to the respective outlet ¢ on the impeller. These Blades form helically twisted channels for the liquid to be conveyed. The cross-section of these guide channels is reduced in a manner known per se from the suction nozzle to the outlet gradually, creating an increase in the relative Exit speed compared to - over the relative entry speed of the-to promoting liquid is achieved.
Um den Wirkungsgrad der Pumpe zu steigern; können in an sich bekannter Weise zwischen die Schaufeln 3 noch Zwischenschaufeln 5 eingebaut werden.To increase the efficiency of the pump; can be known in and of itself Way between the blades 3 nor 5 intermediate blades are installed.
Die Arbeits- und Wirkungsweise der Pumpe ist folgende: Wird das Laufrad in Richtung des Pfeiles A bewegt, so wird die zu fördernde Flüssigkeit von dem Saugstutzen angesogen. Dadurch, daß die Schaufeln.3 des Laufrades hinter der Einsaugöffnung liegen und einen sehr hohen Steigungswinkel aufweisen und in dem parallel zur Welle liegenden Teil des Mantels beginnen, wird die durch den Saugstutzen des Gehäuses in das Laufrad übertretende Flüssigkeit als geschlossene Säule in dieses eingesaugt und wird nicht mit oder vor Beginn ihrer Rotation von den Schaufeln zerschnitten, sondern erst nach Einsetzen ihrer Rotation innerhalb des Laufrades durch diese gewissermaßen auf die Schaufeln gehoben und dann durch die von den Schaufeln gebildeten Kanäle von innen nach außen unter ständiger Zunahme der Geschwindigkeit bis zu den Austrittsöffnungen q. des Laufrades befördert.The working and functioning of the pump is as follows: becomes the impeller Moved in the direction of arrow A, the liquid to be pumped is removed from the suction nozzle sucked in. Because the blades. 3 of the impeller behind the intake opening lie and have a very high pitch angle and in that parallel to the shaft the lying part of the jacket begins, which is through the suction port of the housing Liquid entering the impeller is sucked into the impeller as a closed column and is not cut by the blades with or before they start to rotate, but only after the onset of their rotation within the impeller by this to a certain extent lifted onto the blades and then through the channels formed by the blades from the inside to the outside with a constant increase in speed up to the outlet openings q. of the impeller.
