Description

Die Erfindung betrifft ein Pumpengehäuse mit einem Druck- und/oder Saugstutzen, mit dem das Gehäuse an eine Leitung anschließbar ist, wobei der Stutzen von einem verdrehbaren ringförmigen Befestigungsflansch umgeben ist, an dem die Leitung befestigbar insbesondere anschraubbar ist. Die DE 594 105 A1 zeigt ein solches Pumpengehäuse. Verdrehbare ringförmige Befestigungsflansche an den Stutzen eines Pumpengehäuses haben den Vorteil, dass Rohre mit unterschiedlichsten Befestigungsarten befestigt werden können, ohne das Pumpengehäuse selber bzw. deren Stutzen verändern zu müssen. Hierbei hat es sich aber gezeigt, dass eine sichere Lagerung des verdrehbaren ringförmigen Befestigungsflansches konstruktiv aufwendig ist.The invention relates to a pump housing with a pressure and / or suction nozzle, with which the housing is connectable to a line, wherein the nozzle is surrounded by a rotatable annular mounting flange to which the line is fastened in particular screwed. The DE 594 105 A1 shows such a pump housing. Rotatable annular mounting flanges on the neck of a pump housing have the advantage that pipes with a variety of types of fastening can be attached without having to change the pump housing itself or its neck. In this case, it has been shown that a secure mounting of the rotatable annular mounting flange is structurally complex.

Aufgabe der Erfindung ist es, die Lagerung eines verdrehbaren ringförmigen Befestigungsflansches am Stutzen eines Pumpengehäuses konstruktiv einfach und sicher zu gestalten bei einfacher Herstellung und Montage.The object of the invention is to make the storage of a rotatable annular mounting flange on the nozzle of a pump housing structurally simple and secure with ease of manufacture and assembly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Stutzen ein Innengewinde aufweist, in das eine Buchse mit ihrem Außengewinde einschraubbar ist, und dass die Buchse einen Flansch bildet, an dem der ringförmige Befestigungsflansch anliegt.This object is achieved in that the nozzle has an internal thread into which a socket with its external thread can be screwed, and that the socket forms a flange against which abuts the annular mounting flange.

Durch eine solche Konstruktion wird eine besonders einfache und sichere Lagerung des ringförmigen Befestigungsflansches am Pumpenstutzen ermöglicht, wobei Herstellung und Montage besonders einfach sind.By such a construction, a particularly simple and secure mounting of the annular mounting flange is made possible on the pump nozzle, wherein production and assembly are particularly simple.

Eine einfache Konstruktion bei geringen Abmessungen wird erreicht, wenn der Flansch auf dem dem Gehäuse abgewandten Ende an der Buchse angeordnet ist.A simple construction with small dimensions is achieved when the flange is disposed on the end facing away from the housing to the socket.

Vorzugsweise wird vorgeschlagen, dass der ringförmige Befestigungsflansch in insbesondere regelmäßigen Abständen Bohrungen für Schraubbefestigungen aufweist. Besonders vorteilhaft ist es, wenn der ringförmige Befestigungsflansch zwischen den Bohrungen vorstehende Teile insbesondere Rippen aufweist, zur Anlage von Anflachungen von Muttern oder Schraubköpfen. Hierdurch wird ein verdrehsicherer Halt der Muttern oder der Schraubenköpfe während der Montage erreicht.Preferably, it is proposed that the annular mounting flange has holes for screw fasteners in particular regular intervals. It is particularly advantageous if the annular attachment flange has protruding parts, in particular ribs, between the bores, for the abutment of nuts or screw heads. As a result, a rotationally secure hold of the nuts or screw heads is achieved during assembly.

Vorzugsweise bildet das Pumpengehäuse den unteren Bereich einer mehrstufigen Pumpe, wobei auf der der Saugöffnung gegenüberliegenden Seite am Gehäuse ein Gehäuserohr befestigt ist, in dem zwei oder mehr Pumpenlaufräder auf der Pumpenwelle angeordnet sind.Preferably, the pump housing forms the lower portion of a multi-stage pump, wherein on the opposite side of the suction port on the housing, a housing tube is fixed, in which two or more pump impellers are arranged on the pump shaft.

Gewicht und Kosten werden eingespart, wenn an der Gehäuseunterseite eine Grundplatte aus Blech befestigt ist.Weight and costs are saved if a base plate made of sheet metal is attached to the underside of the housing.
