Dem Ausbau ein- und mehrstufiger Zentrifugalpumpen bezw. -Gebläse als Normalien, wie es die Wirtschaftlichkeit verlangt, treten große Schwierigkeiten entgegen, vor allem durch das Verlangen der direkten Kupplung mit Motoren, die teilweise begrenzte Tourenveränderung haben, dann aber auch an feste unverrückbare Tourenzahlen gebunden sind wie die Drehstrommotoren. Die bei einemThe expansion of single and multi-stage centrifugal pumps resp. -Blower as standard parts, as the economy demands, great difficulties arise, above all by the demand for direct coupling with motors, the partially limited tour change but are also tied to fixed, immovable number of revolutions like three-phase motors. The one with one
ίο Projekt vorliegenden Verhältnisse der Wassermenge und Druckhöhe erfordern fast immer von Fall zu Fall ein erneutes Anpassen. Trotz dieser Schwierigkeiten muß es aber das Bestreben bleiben, die Normalisierung so weit als möglich durchzuführen. Durch vorliegenden Erfindungsgedanken ist nun die fortdauernde Verwendung der hauptsächlichsten Modelle des Saugstückes A, des Mittelstückes B, des Druckstückes C, derίο The conditions of the water volume and pressure height present in the project almost always require readjustment on a case-by-case basis. Despite these difficulties, however, the endeavor must remain to carry out the normalization as far as possible. By the present inventive concept, the continued use of the main models of the suction piece A, the middle piece B, the pressure piece C, the
ao Scheidewände D und E (Fig. 1) ermöglicht, so daß von Fall zu Fall nur neue Lauf- und Leiträder, die allein die Lieferung und Druckhöhe bestimmen und dementsprechend breiter oder schmäler, größer oder kleiner im Durchmesser sind, eingesetzt zu werden brauchen. Die Ermöglichung ist dadurch herbeigeführt, daß in den reichlich bemessenen Innenräumen I, 2, 3, die von den Gehäuseteilen A, B, C gebildet werden, die tellerförmigen Scheidewände D und E, die sonst mit den Gehäuseteilen B und C starr verbunden sind, losgelöst wurden, also achsial verschiebbar gemacht sind, wobei sie gegen drehende Kräfte entweder durch das Anliegen und Hineingreifen ihrer Rippen H und / gegen und in die Rippen K und L des Gehäuses, wie die Zeichnung zeigt, oder durch eine beliebige Arretierung gesichert und durch den während des Arbeitens sich bildenden Wasserdruck auf der Rückseite der Scheidewände D und E gegen die offenen oder geschlossenen Leiträder oder, falls diese angegossen sind, mit ihnen gegen die Gehäuseteile A, B gepreßt werden.ao partitions D and E (Fig. 1) allows, so that from case to case only new impellers and idlers, which alone determine the delivery and pressure level and are accordingly wider or narrower, larger or smaller in diameter, need to be used. This is made possible by the fact that the plate-shaped partitions D and E, which are otherwise rigidly connected to the housing parts B and C , are detached in the ample interior spaces I, 2, 3, which are formed by the housing parts A, B, C were, so made axially displaceable, being secured against rotating forces either by the application and engagement of their ribs H and / against and in the ribs K and L of the housing, as the drawing shows, or by any locking device and by the during of the working water pressure on the back of the partitions D and E against the open or closed guide wheels or, if these are cast, are pressed with them against the housing parts A, B.
Neue Radsätze für andere Förderhöhen und Wassermengen können also immer eingesetzt werden, auch eine nachträgliche andere Verwendung der Pumpe ist somit ermöglicht.New wheel sets for different delivery heights and water volumes can therefore always be used The pump can also be used for other purposes at a later date.
