Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Zur Erhöhung der Nutzleistung der Zentrifugalpumpen verwendet man Leitschaufelkränze, welche das Flügelrad ringförmig umgeben. Dieselben haben die Aufgabe, den Wasserübertritt aus dem Flügelrad nach dem Druckraume der Pumpe möglichst stoßlos zu vermitteln. -To increase the useful power of the centrifugal pumps, guide vane rings are used, which surround the impeller in a ring. They have the task of Water flows from the impeller to the pressure chamber of the pump as smoothly as possible convey. -

In beiliegender Zeichnung ist _/'das Flügelrad einer Pumpe mit Leitschaufelkranz, α der Leitschaufelkranz, c dessen im Druckraum liegende eine Seitenwand, während die andere durch den Pumpendeckel d gebildet ist. Der Leitschaufelkranz ist mittels Flansch e an der Gehäusewand befestigt und abgedichtet. Um den stoßlosen Übertritt des Wassers aus dem Flügelrad nach dem Druckraum noch vollständiger als bei der gewöhnlichen Anordnung zu erreichen, ist der Leitschaufelkranz α seitlich im Druckraume b angeordnet, so daß die vordere, am Pumpendeckel d anschließende Wand des Leitschaufelkranzes tangential zur Wandung des Druckraumes verläuft. Hierdurch wird erreicht, daß die aus dem Leitrad tretenden Wasserstrahlen nicht an die Gehäusewand anprallen, sondern allmählig abgelenkt in spiralförmiger Bahn in den Druckraum und infolgedessen möglichst stoßlos übertreten. In the accompanying drawing, _ / 'is the impeller of a pump with a guide vane ring, α the guide vane ring, c one side wall of which is located in the pressure chamber, while the other is formed by the pump cover d. The guide vane ring is fastened and sealed to the housing wall by means of flange e. In order to achieve the smooth transfer of the water from the impeller to the pressure chamber even more completely than with the usual arrangement, the guide vane ring α is arranged laterally in the pressure chamber b , so that the front wall of the guide vane ring adjoining the pump cover d runs tangentially to the wall of the pressure chamber . This ensures that the water jets emerging from the stator do not hit the housing wall, but are gradually deflected in a spiral path into the pressure chamber and consequently pass as smoothly as possible.

Claims (1)

Patent-Anspruch :Patent claim: Zentrifugalpumpe mit einem das Flügelrad umgebenden und im Druckraum liegenden Leitschaufelkranz, dadurch gekennzeichnet, daß der Gehäusedeckel (d) die Vorderwand der Leitschaufelkanäle bildet und diese Vorderwand tangential am Druckraum sich anschließt, damit die aus dem Leitschaufelkranz tretende Flüssigkeit an die Gehäusewand "des Druckraumes nicht vertikal anprallt, sondern tangential abgelenkt wird, zum Zweck, möglichst wenig von ihrer lebendigen Kraft durch Stoß zu verlieren.Centrifugal pump with a guide vane ring surrounding the impeller and located in the pressure chamber, characterized in that the housing cover (d) forms the front wall of the guide vane channels and this front wall is tangentially connected to the pressure chamber so that the liquid emerging from the guide vane ring does not reach the housing wall "of the pressure chamber vertically but is deflected tangentially in order to lose as little as possible of its vital force through impact. Hierzu ι Blatt Zeichnungen.For this purpose ι sheet of drawings.
