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.
