Abstract
Es wird eine mit einer Umschaltklappe ausgestattete Umschalteinrichtung für Doppelpumpenaggregate vorgeschlagen, bei der zwei an der Achse der Umschaltklappe angebrachte, in Vertiefungen im Druckstutzen des Pumpen aggregates einrastbare Schenkel vorgesehen sind. Die Vertiefungen im Gehäuse des Pumpenaggregates und die darin einrastenden federnden Schenkel bringen eine Verringerung des für die Anbringung der Klappe erforderlichen Aufwandes insofern mit sich, als eine mechanische Bearbeitung erübrigt wird.A switching device equipped with a switchover flap is proposed for double pump units, in which two legs are provided which are attached to the axis of the switchover flap and can be snapped into recesses in the pressure port of the pump unit. The depressions in the housing of the pump assembly and the resilient legs latching into them reduce the effort required for attaching the flap insofar as mechanical processing is unnecessary.
Description
1515th
Die Erfindung betrifft eine Umschalteinrichtung für ein aus zwei unabhängig voneinander zu betreibenden Kreiselpumpen bestehendes Pumpenaggregat, mit einer im Druckstiften des Pumpenaggregates angeordneten, die Abfiußsske der jeweils stehenden Kreiselpumpe versperrenden Umschaltklappe.The invention relates to a switching device for one of two to be operated independently of one another Pump unit with existing centrifugal pumps, with one arranged in the pressure pin of the pump unit, the outflow of each stationary centrifugal pump locking switchover flap.
Derartige Umschalteinrichtungen sind allgemein bekannt. Als Beispiel sei die DE-PS 22 37 108 genannt, die in ihrer Zeichnung eine auf der Druckseite des Aggregates angeordnete Umschaltklappe zeigt. Die Umschaltklappe ist um eine im-Sehäuse des Pumpenaggregates vorgesehene Achse zwischen zwei an den Auslassen der Kreiselpumpen angebrachten Sitzflächen schwenkbar. Durch den von einer laufenden Kreiselpumpe erzeugten Druck wird die Umschaltklappe von einer Sitzfläche abgehoben und auf die Sitzfläche der stehenden Kreiselpumpe dichtend aufgepreßt oder, sofern beide Kreiselpumpen laufen, in einer Mittellage gehalten.Such switching devices are generally known. DE-PS 22 37 108 is an example, which shows in its drawing a switchover flap arranged on the pressure side of the unit. the Switching flap is around an axis provided in the housing of the pump unit between two of the Leaving out the centrifugal pumps attached seats can be swiveled. By a running centrifugal pump generated pressure, the changeover flap is lifted from a seat and onto the seat of the standing centrifugal pump pressed on tightly or, if both centrifugal pumps are running, in a central position held.
Die Befestigung der Umschaltklappe bzw. die Anordnung der die Umschaltklappe tragenden Achse im Gehäuse des Pumpeuaggregates machte bisher eine mechanische Bearbeitung des Gehäuses notwendig. Diesen Aufwand zu erübrigen, hat sich die Erfindung zur Aufgabe gemacht. : The attachment of the switchover flap or the arrangement of the axis carrying the switchover flap in the housing of the pump unit has previously made mechanical processing of the housing necessary. The invention has set itself the task of eliminating this expense. :
Eine ohne mechanische Bearbeitung im Gehäuse eines Pumpenaggregates einsetzbare Ursischdieinrichtung mit Umschaltklappe wird erfindungsgemäß ermöglicht durch zwei an der Achse der Umschaltklappe angebracht, in Vertiefungen im Druckstutzen einrastbare federnde SchenkeLAn Ursischdi device that can be used in the housing of a pump unit without mechanical processing with switchover flap is made possible according to the invention by two on the axis of the switchover flap attached, resilient legs that can be snapped into recesses in the pressure port
Die Vertiefungen im Gehäuse des Pumpenaggregates können beispielsweise bei einem Gußstück, als keiner weiteren Bearbeitung bedürftige Konturen mit vorgesehen werden. Die Umschaltk'appe ist mitsamt einem die Achse und die federnden Schenkel bildenden Bügel in den Druckstutzen des Gehäuses anbringbar, wobei die federnden Schenkel dann nur noch in die vorhandene Vertiefung einrasten müssen.The recesses in the housing of the pump unit can, for example, be a casting, as none Contours that require further processing can also be provided. The Umschaltk'appe is together with one the Axis and the resilient legs forming bracket can be mounted in the pressure port of the housing, wherein the resilient legs then only have to snap into the existing recess.
Anhand eines Ausföhrungsbeispiels wird die Erfindung näher erläutert. Die Zeichnung zeigt inThe invention is based on an exemplary embodiment explained in more detail. The drawing shows in

Im Druckstutzen 1 eines — nur ausschnittweise dargestellten — Pumpenaggregates ist eine um eine Achse 2 schwenkbare Umschaltklappe 3 angeordnet. Die Achse 2 geht über in federnde Schenkel 4,5, welche in gegossene Vertiefungen 6 im Druckstutzen 1 einrasten.In the pressure port 1 of a - only partially shown - pump assembly is a Axis 2 pivotable switchover flap 3 is arranged. The axis 2 goes over into resilient legs 4.5, which Snap into cast indentations 6 in pressure port 1.
