Description

Tiefbrunnenpumpa Die Erfindung betrifft eine Tiefbrunnenpumpe mit unmittelbar angebautem elektrischem Motor, bei der Zum Schutze des Motors gegen Eindringen von Wasser ein unten offenes Rohr angesetzt und das Saugrohr entsprechend tief herabgeführt ist. Die Vorrichtung wirkt nach Art einer Taucherglocke und ist so bemessen, daß auch bei größter Tauchtiefe das Wasser in dem Rohr nur so weit steigt, daß es nicht in den Motor eindringen kann.Deep well pump The invention relates to a deep well pump directly attached electric motor, in order to protect the motor against Ingress of water a pipe open at the bottom is attached and the suction pipe accordingly is brought down deep. The device acts like a diving bell and is dimensioned in such a way that even at the greatest depth the water in the pipe is only so far increases so that it cannot penetrate the engine.

Erfindungsgemäß wird das Druckrohr für die Wasserabführung in der Motor- und Pumpenachse angeordnet. Es fallen infolgedessen die äußeren Druckwasserkanäle im Pumpengehäuse fort, der Durchmesser des Motorständers und vor allem der des Motorankers kann bei gleichem Außendurchmesser der Pumpe vergrößert werden. Ferner ist der Anschlizß .der Druckleitung an den oberen Teil des Pumpengehäuses vermieden, dessen sichere Abdichtung sehr schwierig ist.According to the invention, the pressure pipe for the water drainage in the Motor and pump axis arranged. As a result, the outer pressurized water channels fall in the pump housing, the diameter of the motor stand and especially that of the motor armature can be increased with the same outside diameter of the pump. Furthermore, the connection .the pressure line to the upper part of the pump housing avoided, its safe Sealing is very difficult.

Ein Ausführungsbeispiel der Erfindung wird durch die Zeichnung im Schnitt dargestellt. i ist ein zylindrisches Rohr, das den Elektromotor umschließt und nach unten über ihn so weit verlängert ist, daß, die oben beschriebene Wirkung der Taucherglocke eintreten kann. Das obere Ende des Rohres i ist durch den Deckel z luftdicht verschlossen. Durch das Loch 3 in dem Deckel 2 wird das Stromkabel für den Motor luftdicht geführt. An das untere Ende des Rohres i ist das Pumpengehäuse 4 mit der Wasserzuführung, den Leitkanälen und der Abführung des Druckwassers angeschraubt. Das an das Gehäuse 4 angesetzte Druckrohr 5 ist zentral durch das Rohr i und luftdicht durch den Deckel z geführt. 6 ist der Stator und 7 der Anker des Elektromotors. Der Anker 7 und der rotierende Teil 8 der Druckpumpe sitzen auf der gemeinsamen hohlen Welle 9, die auf dem Druckrohr 5 bei i o, i i und i a gelagert ist. An dem unteren Ende ist das Rohr i durch eine Schutzwand 13 abgeschlossen, die den Hohlraum des Rohres i, der mit der durch den äußeren Wasserdruck komprimierten Luft angefüllt ist, gegen hochspritzendes Wasser und etwa darin enthaltene Fremdkörper schützt. Die Schutzwand ist so angeordnet, daß sie selbst bei dem größten vorkommenden Wasserdruck über dem Wasserspiegel liegt. Um aber der Luft den Durchgang zu gestatten, ist sie mit kleinen Löchern 14 versehen. An der Durchführungsstelle der Welle 9 ist eine weiche Packung 15 eingelegt.An embodiment of the invention is illustrated by the drawing in Section shown. i is a cylindrical tube that encloses the electric motor and is extended downward over it so far that, the above-described effect the diving bell can enter. The upper end of the tube i is through the lid z hermetically sealed. Through the hole 3 in the lid 2, the power cable for the engine is airtight. At the lower end of the tube i is the pump housing 4 screwed on with the water supply, the guide channels and the discharge of the pressurized water. The pressure pipe 5 attached to the housing 4 is centrally through the pipe i and airtight passed through the cover z. 6 is the stator and 7 is the armature of the electric motor. The armature 7 and the rotating part 8 of the pressure pump sit on the common hollow shaft 9 which is mounted on the pressure pipe 5 at i o, i i and i a. To the The lower end of the tube i is closed off by a protective wall 13 that encompasses the cavity of the pipe i, which is filled with the air compressed by the external water pressure protects against splashing water and any foreign bodies it contains. The protective wall is arranged so that it can even with the greatest occurring water pressure above the water level. But in order to allow the air to pass through, it is provided with small holes 14. At the implementation point of the shaft 9 is a soft pack 15 inserted.

Das Pumpenaggregat arbeitet nun folgendermaßen Beim Eintauchen der Pumpe in den Brunnen gelangt durch die Löcher 16 Wasser in den Hohlraum 17 und steigt unter Zusammenpressen der in dem Rohr i eingeschlossenen Luft. Wird der Elektromotor angelassen, so fließt das Wasser in der Pfeilrichtung durch die Pumpe und wird srhIießlich durch das Druckrohr 5 nach oben befördert. . Je tiefer die Pumpe in das Wasser eintaucht, desto höher wird der Wasserspiegel in dem als Taucherglocke wirkenden zylindrischen Rohr i ansteigen. Der über dem Wasser befindliche Luftraum ist so bemessen, daß selbst bei der größten Tauchtiefe das Wasser nicht bis zu der Schutzwand 13 herankommt, und wo der als Luftpuffer wirkende Raum 18 über der Schutzwand 13 nicht vom Wasser benetzt wird. Das etwa durch Kondensation sich an der Motorwelle bildende und von dort abspritzende Wasser wird schließlich durch das unmittelbar unter dem Motor angebrachte Leitblech i9 abgefangen und so von dem Motor ferngehalten.The pump assembly now works as follows. When the pump is immersed in the well, water passes through the holes 16 into the cavity 17 and rises, compressing the air enclosed in the pipe i. When the electric motor is started, the water flows through the pump in the direction of the arrow and is ultimately conveyed upwards through the pressure pipe 5. . The deeper the pump is immersed in the water, the higher the water level will rise in the cylindrical tube i, which acts as a diving bell. The air space above the water is dimensioned so that even at the greatest depth the water does not get as far as the protective wall 13, and where the space 18 above the protective wall 13 acting as an air buffer is not wetted by the water. The water that forms on the motor shaft as a result of condensation and splashes off from there is finally intercepted by the baffle plate i9 attached directly below the motor and thus kept away from the motor.

Bei dem Ausführungsbeispiel muß, die Pumpe verhältnismäßig tief unter denn Motor angeordnet sein, damit die Taucherglockenwirkung vorhanden ist. Wird die Pumpe mit einem besonderen Saugrohr versehen, so kann sie dicht- unter dem 'Motor angebracht werden. Die gemeinsame Welle 9 wird dann kürzer und deren Lagerung einfacher.In the embodiment, the pump must be relatively deep below because the motor must be arranged so that the diving bell effect is present. Will the pump is provided with a special suction pipe so that it can be placed close to the motor be attached. The common shaft 9 is then shorter and its storage easier.
