Description

Drehkolbenpumpe mit exzentrisch im Gehäuse umlaufender Kolbentrommel und Schieberkolben. Gegenstand der Erfindung ist eine Drehkolbenpumpe mit exzentrisch im Gehäuse umlaufender Kolbentrommel und Schieberkolben, die weder unter Federwirkung noch unter der Einwirkung der Fliehkraft stehen. Die Schieberkolben sind vielmehr in bekannter Weise frei beweglich- in Schlitzen der Kolbentrommel in einer derartigen Neigung gegenüber der Radialen angeordnet, daß die Fliehkraft nicht zur Einwirkung kommen kann. Das Andrücken der Schieberkolben an die Gehäusewandung erfolgt durch das Spaltwasser der Pumpe, welches in einem Druckausgleichraum im Innern der Kolbentrommel auf die inneren Stirnflächen der Schieberkolben zur Einwirkung gebracht wird.Rotary lobe pump with piston drum rotating eccentrically in the housing and spool. The invention relates to a rotary lobe pump with an eccentric Piston drum and slide piston rotating in the housing, which are neither under spring action are still under the influence of centrifugal force. Rather, the spool pistons are freely movable in a known manner in slots of the piston drum in such a way Inclination relative to the radial arranged so that the centrifugal force does not have to act can come. The slide piston is pressed against the housing wall by the Crack water from the pump, which is in a pressure equalization space inside the piston drum is brought to act on the inner end faces of the spool.

Drehkolbenpumpen, deren Schieber nicht unter Federwirkung stehen, sind an sich bekannt. Die Schieberkolben dieser bekannten Drehkolbenpumpen sind jedoch sowohl der Fliehkraft als dem Druck des Fördermittels unterworfen. Die Schieberkolben sind nämlich radial in der Kolbentrommel gelagert und werden infolgedessen bereits durch die Fliehkraft an die Wandung des Kolbengehäuses gedrückt. Diese Wirkung wird verstärkt durch das Fördermittel, so daß ein zu starker Reibungsdruck zwischen Schieberkolben und Gehäusewandung eintritt.Rotary lobe pumps whose vanes are not subject to spring action, are known per se. The slide pistons of these known rotary lobe pumps are however subject to both centrifugal force and the pressure of the conveyor. The spool are namely mounted radially in the piston drum and are therefore already pressed against the wall of the piston housing by centrifugal force. This effect will reinforced by the conveyor, so that too much frictional pressure between the slide piston and housing wall occurs.

Demgegenüber ist beim Anmeldungsgegenstand die Fliehkraft vollkommen ausgeschaltet und außerdem der Anpressurigsdruck durch das Fördermittel etwa um die Hälfte verringert, weil nicht das Fördermittel unmittelbar auf die Schiebcrkolben einwirkt, sondern der Druck des Spaltwassers der Pumpe, welcher etwa der halben Förderhöhe entspricht.In contrast, the subject matter of the application, the centrifugal force is perfect turned off and also the contact pressure by the conveyor about around reduced by half, because the conveying means are not directly on the slide piston acts, but the pressure of the gap water of the pump, which is about half that Corresponds to the delivery rate.

Auf der -Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigt die Pumpe: Abb. i im Querschnitt und Abb. 2 im Längsschnitt.The subject of the invention is shown in an exemplary embodiment on the drawing shown. It shows the pump: Fig. I in cross section and Fig. 2 in longitudinal section.

Die Kolbentrommel besteht aus einem zentrisch auf der Welle i sitzenden Zylinder 2 mit auf den Stirnflächen angeschraubten Deckeln 3 und mit sechs etwa unter 45° gegen die Radiale geneigten Schlitzen 4 zur Aufnahme der Schieberkol'ben 5.The piston drum consists of a center seated on the shaft i Cylinder 2 with lids 3 screwed onto the end faces and approximately six Slits 4 inclined at 45 ° to the radial for receiving the slide pistons 5.

Die Kolbentrommel 2 liegt mit ihrer Welle i exzentrisch im Pumpengehäuse 8; dessen Saug- und Druckstutzen tangential in den zylindrischen Arbeitsraum einmünden. Der Arbeitsraum der Pumpe wird seitlich durch zwei mit angedrehten Paßringen versehene Lagerdeckel 1i, 1a abgeschlossen, welche mittels Schrauben am Gehäuse befestigt sind.The piston drum 2 lies with its shaft i eccentrically in the pump housing 8th; whose suction and pressure nozzles open tangentially into the cylindrical working space. The working space of the pump is provided with two fitted rings on the side Bearing cover 1i, 1a completed, which is fastened to the housing by means of screws are.

Inder Kolbentrommel 2 befindet sich eine ringförmige Ausdrehung 6 als Verbindungs-oder Druckausgleichraum zwischen den einzelnen Schlitzen 4. Dieser Ringraum 6 steht durch achsiale, die Kolbentrommel z und Dekkel 3 durchsetzende Kanäle 7 mit Ringräumen 9 in Verbindung, die durch eine Ausdrehung der Lagerdeckel i r, 12, zwischen ,diesen und den Kolbentrommeldeckeln 3- erzeugt sind. Durch die Spalte io zwischen Kolbentrommeldeckeln 3 und Lagerdeckeln i i, r2 ist eine Verbindung zwischen den Ringräumen 9 und dem Arbeitsraum der Pumpe hergestellt.An annular recess 6 is located in the piston drum 2 as a connection or pressure equalization space between the individual slots 4. This Annular space 6 stands through axial, the piston drum z and cover 3 penetrating Channels 7 with annular spaces 9 in connection, which by turning the bearing cover i r, 12, between, these and the piston drum covers 3- are generated. Through the Column io between piston drum covers 3 and bearing covers i, r2 is a connection produced between the annular spaces 9 and the working space of the pump.

Die Wirkungsweise der Pumpe ist folgende: Bei der Drehung der Kolbentrommel in der Pfeilrichtung d werden die Schieberkolben 5 auf der Saugseite der Pump;. nach außen gegen die Gehäusewandung gedrückt durch das Spaltwasser, das durch die Ringräume 9 und .die Kanäle 7 in den Druckausgleichraum 6 eintritt und in diesem auf die inneren Stirnflächen der Schieberkolben 5 mit einem etwa der halben Förderhöhe entsprechenden Druck einwirkt. Die Rückführung der Schieberkolben 5 auf der Druckseite wird durch die Gehäusewandung unmittelbar verursacht unter Überwindung des Druckes der auf den Schieberkolben lastenden Wassersäule.The pump works as follows: When the piston drum rotates in the direction of the arrow d, the slide piston 5 on the suction side of the pump; pressed outwards against the housing wall by the crack water that flows through the Annular spaces 9 and .the channels 7 enter the pressure equalization space 6 and in this on the inner end faces of the spool 5 with approximately half the delivery head corresponding pressure acts. The return of the spool 5 on the pressure side is caused directly by the housing wall by overcoming the pressure the column of water bearing down on the valve piston.

Die zwischen Schieberkolben und Gehäusewandung auftretende Reibung ist, wie eingehende Versuche bewiesen haben, so gering, daß sich selbst nach 6oo Betriebsstunden kaum eine Abnutzung der zweckmäßigerweise aus Hartgummi o. dgl. bestehenden Schieberkolben gezeigt hat.The friction that occurs between the spool and the housing wall is, as detailed experiments have shown, so small that even after 600 Operating hours hardly any wear and tear, which is expediently made of hard rubber or the like. existing spool has shown.
