Description

Unter den Wasserspiegel versenkbare Tiefbrunnenpumpe. Die Erfindung betrifft eine unter den Wasserspiegel versenkbare Tiefbrunnenpumpe mit elektrischem Antrieb, bei welcher in einem schlanken Gehäuse, nach Art einer Taucherglocke, ein Elektromotor und darunter, mit diesem durch eine hohle Welle verbunden, eine Kreiselpumpe vorgesehen sind und die Hohlwelle als Steigrohr dient. Gegenüber den bekannten Pumpwerken dieser Art, bei welchen Abdichtungen beim Austritt der rotierenden Hohlwelle aus dem Taucherglockengehäuse und zwischen Motor und Pumpe vorhanden sein müssen, besteht die Erfindung darin, daß das Steigrohr von der Gehäusedecke her als Tauchrohr in die Hohlwelle hinabragt. Durch diese Anordnung werden die genannten Abdichtungen vermieden, so daß, bei vollständigem Wasserabschluß zum Elektromotor, kraftverbrauchende Stopfbüchsenreibungen ausgeschlossen sind.Deep well pump that can be sunk below the water level. The invention relates to a submersible deep well pump with electric Drive in which in a slim housing, like a diving bell, a Electric motor and below, connected to this by a hollow shaft, a centrifugal pump are provided and the hollow shaft serves as a riser pipe. Compared to the well-known pumping stations of this type, in which seals when the rotating hollow shaft exits the diving bell housing and between the motor and the pump the invention is that the riser pipe from the top of the housing as a dip tube in the hollow shaft protrudes. This arrangement makes the seals mentioned avoided, so that, with complete water exclusion to the electric motor, power consuming Stuffing box rubbing is excluded.

Iri der Zeichnung äst ein Ausführungsbeispiel Ü !es Erfindungsgegenstandes dargestellt, und es beideuten: adas;Brunnenrohr, bdiePump e, C den Elektromotor, d die Hohlwelle, e das Tauchrohr, g das Steigrohr, lt das Stromzuführungskabed: f ist eine Abdichtung zwischen dem Gehäuse und dem Steigrohr, die aber nicht durchaus notwendig ist, da diese beiden feststehenden Teile auch anders miteinander verbunden sein können. Jedenfalls betrifft diese Abdichtung keine sich drehenden Teile, wie die Hohlwelle der bekannten Pumpen, so daB hier Undichtigkeiten vollkommen vermieden werden können ohne Reibungsverlust.In the drawing, an exemplary embodiment is the subject of the invention and it both utes: adas; well pipe, bdiePump e, C the electric motor, d the hollow shaft, e the immersion tube, g the riser tube, lt the power supply cable: f is a seal between the housing and the riser pipe, but this is not absolutely is necessary because these two fixed parts are also connected to each other differently could be. In any case, this seal does not affect rotating parts, such as the hollow shaft of the known pumps, so that leaks are completely avoided here without loss of friction.

Die unterhalb der Gehäusedecke endende, oben offene Hohlwelle d ist am unteren Ende gelocht, und das Tauchrohr ee '.reicht bis zu dieser Stelle hinab, so daß das durch die Kreiselpumpe geförderte Wasser im Gehause nur so weit über die Unterkante des Tauchrohrs steigen kann, als es die unter dem statischen Druck der Wassersäule im Steigrohr stehende Luft im oberen, den Elektromotor umgebenden Gehäuseteil gestattet. Abgesehen davon, daß dieser Teil als Windkessel wirkt, der allerdings bei Kreiselpumpen weniger wichtig ist, schützt er durch die zusammengepreßte Luft den Motor gegen das Förderwasser, wobei Stöpfbüchsenreibungen vollständig wegfallen.The hollow shaft d is open at the top and ends below the housing cover at the bottom perforated, and the immersion tube ee '. reaches up to this Place down so that the water pumped by the centrifugal pump in the housing only can rise as far above the lower edge of the immersion tube as the one below the static one Pressure of the water column in the riser pipe, standing air in the upper, surrounding the electric motor Housing part permitted. Apart from the fact that this part acts as an air chamber, the However, it is less important for centrifugal pumps, it protects through the compressed Air the motor against the feed water, completely eliminating plug-box friction.

PATENTANSPRUCH: Unter den Wasserspiegel versenkbare Tiefbrunnenpumpe, die, durch eine beiderseitig offene Hohlwelle mit einem Barüberliegenden Elektromotor verbunden, in einem als Taucherglocke wirkenden Gehäuse angeordnet ist, dadurch gekennzeichnet, daß das an sich bekannte achsial gelagerte Steigrohr als Tauchrohr in die Hohlwelle bis unter die Unterkante des Motors hinabragt, so daß der obere Gehäuseteil als Pumpenwindkessel wirkt, in dem der Motor vor Wasser geschützt liegt. PATENT CLAIM: A deep well pump which can be sunk below the water level and which is connected by a hollow shaft open on both sides with an electric motor overlying the bar, is arranged in a housing acting as a diving bell, characterized in that the axially mounted riser pipe known per se as a dip pipe in the hollow shaft to below the lower edge of the motor protrudes so that the upper part of the housing acts as a pump air tank in which the motor is protected from water.
