BeschreibungDescription
Exzenterschnecken-Tauchpumpen üblicher Bauart weisen für die Ansaugung von Pumpmedien, die stark 2x1 Sedimentation, d.h. zu einer Entmischung von festen und flüssigen Bestandteilen neigen (z.B. Zementschlämme, Farbschlämme, etc.), keine entsprechend wirkungsvollen Einrichtungen auf, die eine Homogenisation des Pumpmediums ermöglichen. Vielfach werden hierfür gesonderte Rührwerkseinrichtungen eingesetzt.Eccentric screw submersible pumps of the usual design do not have any correspondingly effective devices for the suction of pump media that have a strong tendency towards 2x1 sedimentation, i.e. towards a separation of solid and liquid components (e.g. cement slurry, paint slurry, etc.) that enable homogenization of the pump medium. Separate agitator devices are often used for this purpose.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine technisch einfach realisierbare und wirkungsvolle Anordnung zu schaffen, die eine Homogenisation von sedimentierten Pumpmedien für Exzenterschnecken-Tauchpumpen ermöglicht.The invention specified in claim 1 is based on the problem of creating a technically simple and effective arrangement that enables homogenization of sedimented pump media for eccentric screw submersible pumps.
Dieses Problem wird mit den im Schutzanspruch aufgeführten Merkmalen gelöst.This problem is solved with the features listed in the protection claim.
Mit der Erfindung wird eine wirkungsvolle Homogenisation von sedimentierten Pumpmedien erreicht. Außerdem werden durch die Saugwirkung der Pumpe herangeführte Festkörper ab einer bestimmten Größe (begrenzt durch die Geometrie des Sedimenthomogenisators) noch vor dem Pumpenraum durch die rotierende Bewegung abgewiesen.The invention achieves effective homogenization of sedimented pump media. In addition, solids above a certain size (limited by the geometry of the sediment homogenizer) brought in by the suction effect of the pump are rejected by the rotating movement before they reach the pump chamber.
Eine vorteilhafte Ausgestaltung der Erfindung ist in Schutzanspruch 2 angegeben. Die geometrische Ausbildung des Strömungsleitrohres (topfförmig, oben offen) bewirkt eine zusätzliche günstige strömungstechnische Voraussetzung für die durch die exzentrische Drehbewegung des Rührwerkes erzielte Aufwirbelung des Sedimentes. Die angeschliffenen Rührwerksschaufeln ermöglichen auch eine Homogenisation stark sedimentierter Medien.An advantageous embodiment of the invention is specified in claim 2. The geometric design of the flow guide tube (cup-shaped, open at the top) creates an additional favorable flow condition for the stirring up of the sediment achieved by the eccentric rotary movement of the agitator. The ground agitator blades also enable the homogenization of heavily sedimented media.
Ein Ausführungsbeispiel der Erfindung wird anhand der Figur 1 bis 3 erläutert.An embodiment of the invention is explained with reference to Figures 1 to 3.

In den Figuren 1 bis 3 ist die Exzenterschnecken-Tauchpumpe mit Sedimenthomogenisator in verschiedenen Ansichten und Schnitten dargestellt.Figures 1 to 3 show the eccentric screw submersible pump with sediment homogenizer in various views and sections.
Figur 1 zeigt den prinzipiellen Aufbau einer Exzenterschnecken-Tauchpumpe bestehend aus den Komponenten Antrieb (A), Lagerung (B), Tauchrohr (C), Pumpelement (D) und dem Sedimenthomogenisator (E).Figure 1 shows the basic structure of an eccentric screw submersible pump consisting of the components drive (A), bearing (B), immersion tube (C), pump element (D) and the sediment homogenizer (E).
Die für die Erfindung wesentlichen Teile sind in Figur 2 und 3 erkennbar.The parts essential to the invention can be seen in Figures 2 and 3.
Figur 2 stellt einen Schnitt in axialer Richtung dar. Daraus ist die Befestigung des ein- oder mehrflügeligen Rührwerkes (Pos. 3) am Pumpenrotor (Pos. 1), sowie die Schrägstellung der angeschliffenen Rührwerksflügel ersichtlich.Figure 2 shows a section in the axial direction. This shows the attachment of the single or multi-blade agitator (item 3) to the pump rotor (item 1), as well as the inclination of the ground agitator blades.
Figur 3 verdeutlicht die topfförmige, oben offene Geometrie des Strömugsleitrohres.Figure 3 illustrates the cup-shaped, open-topped geometry of the flow guide tube.
