Description
Zentrifugalpumpe. Die Erfindung betrifft eine Zentrifugal pumpe mit zweiseitigem Laufrad und be steht darin, da.ss die Kanäle des Leitappara- tes unter Weglassung eines besonderen Ge häuses in einen die Welle umgebenden Druck stutzen einmünden, wobei zwischen den Ka nälen radiale Öffnungen für den Wasser zufluss freigelassen sind.
Ein Ausführungsbeispiel des Erfindungs gegenstandes ist auf der Zeichnung zur Dar stellung gebracht.
Fig. 1 ist ein Schnitt längs der Linie I-1 der Fig. 2, und Fig. 2 ein Schnitt längs der Linie Il-II der Fig. 1.
a ist das zweiseitige Laufrad, und b die Antriebswelle einer als ssohrlochpumpe ausgebildeten Zentrifugalpumpe, deren Dif- fusor aus einer Mehrzahl von auseinander strebenden Einzelkanälen c besteht. Die Dif- fusorkanäle sind in Richtung der Antriebs welle umgebogen und ihre Austrittsenden so zusammengeführt, dass sie in einen die Welle umgebenden und einen Teil des Pumpen- körpers bildenden Druckstutzen d einmünden, an den die Druckleitung e angeschlossen ist und in welchem das Wellenlager sich befin det.
Jegliches Gehäuse zur Aufnahme der Saugräume ist dabei weggelassen, und die Diffusorkanäle sind so weit voneinander ge trennt geführt, dass die obere Seite .des Lauf rades durch die zwischen ihnen befindlichen Zwischenräume hindurch ebenso wie die un tere Seite des Laufrades direkt aus der Um gebung der Pumpe ansaugen kann.
Centrifugal pump. The invention relates to a centrifugal pump with a two-sided impeller and consists in the fact that the ducts of the diffuser open into a pressure nozzle surrounding the shaft with the omission of a special housing, with radial openings for the flow of water being left between the ducts are.
An embodiment of the subject invention is brought to the drawing for Dar position.
1 is a section along the line I-1 of FIG. 2, and FIG. 2 is a section along the line II-II of FIG.
a is the two-sided impeller, and b the drive shaft of a centrifugal pump designed as a hole pump, the diffuser of which consists of a plurality of diverging individual channels c. The diffuser channels are bent in the direction of the drive shaft and their outlet ends are brought together in such a way that they open into a pressure port d surrounding the shaft and forming part of the pump body, to which pressure line e is connected and in which the shaft bearing is located det.
Any housing to accommodate the suction chambers has been omitted, and the diffuser channels are separated from one another so far that the upper side of the impeller passes through the spaces between them, as does the lower side of the impeller directly from the surroundings Pump can prime.
