Description
Pumpeneinrichtung für Brunnen, Bohrlöcher u. dgl. Die Erfindung betrifft eine Pumpeneinrichtung für Brunnen, Bohrlöcher u. dgl., welche eine in einem Rohr senk- und hebbare, unter Wasser arbeitende und unmittelbar mit einem Elektromotör verbundene sowie in das erwähnte Rohr fördernde Pumpe aufweist, die selbst die Abdichtung zwischen Saug- und Druckraum des Rohres bewirkt.Pump device for wells, boreholes and the like a pump device for wells, boreholes and the like, which one in a pipe can be lowered and raised, working under water and directly with an electric motor connected as well as in the mentioned pipe conveying pump, which itself the seal causes between suction and pressure chamber of the pipe.
Zweck der Erfindung ist, eine Pumpeneüirichtung dieser Art zu schaffen, welche ohne besonderen Windkessel auszukommen ermöglicht und keine unmittelbaren Rohranschlüsse an die Pumpe erfordert, was bei sek- und hebbaren Pumpen besonders vorteilhaft ist. Zu diesem Behufe ragt gemäß vorliegender Erfindung bei einer Pumpeneinrichtung der obenerwähnten Art ein an die Verbrauchsleitung angeschlossenes Rohr im Druckraum des Brunnenrohres nahezu bis zur Pumpe hinab, und es dient das die Pumpe aufnehmende Brunnenrohr gleichzeitig -als Windkessel.The purpose of the invention is to create a pump device of this type, which makes it possible to get by without a special air chamber and no immediate one Pipe connections to the pump are required, which is particularly important with pumps that can be lifted and lifted is advantageous. To this end, protrudes according to the present invention in a pump device of the type mentioned above, a pipe connected to the consumption line in the pressure chamber of the well pipe almost down to the pump, and it is the one that receives the pump Well pipe at the same time as an air vessel.
Auf der beiliegenden Zeichnung ist in einem senkrechten Längsschnitt eine Ausführung einer Brunnenpumpe nach der Erfindung unter Verwendung einer 7entri@ugalpumpe beispielsweise veranschaulicht.The accompanying drawing is a vertical longitudinal section an embodiment of a well pump according to the invention using a 7entri @ ugal pump for example illustrated.
i bezeichnet ein in den Boden eingelassenes Brunnenrohr, in welches . das Wasser von unten Zutritt hat. In dieses Rohr ist ein aus einem Antriebselektromotor 2 und einer Kreiselpumpe 3 bestehender Pumpensatz eingebaut, der von einem das Rohr i oben abschließenden Deckel q. getragen wird, an welchem er mittels eines Seiles 5 aufgehängt ist. Dieses Seil kann, wenn erforderlich, in der -Länge veränderlich gemacht werden, so daß der Pumpensatz 2, 3 im Rohr i auf jede beliebige Höhe eingestellt werden kann. 6 bezeichnet ein Kabel, das zum Zuführen des zum Antreiben des Motors 2 benötigten Stromes dient. Die Pumpe 3 weist -einen Saugkorb 7, ein Laufrad 8, einen Diffusorkanal 9 sowie eine Drosselstelle io auf, welche in Verbindung mit Kanälen i i zur Ausgleichung des Axialschubes der Pumpe dient. Die Pumpe 3 fördert unmittelbar in das Rohr i, wobei die Abdichtung zwischen dem Saugraum 12 und dem Druckraum 13 dieses Rdhres durch die Pumpe selbst bewirkt wird, indem sie mit einer nachgiebigen Dichtung 1¢ versehen ist, welche an die innere Wandung des Rohres i dicht anschließt, jedoch die Einstellmöglichkeit des Pumpensatzes 2, 3 im Rohr i in keiner Weise beeinträchtigt. Die Dichtung 1 ¢ weist eine ringförm.Lge Aussparung 15 auf, zu welcher das Druckwasser Zutritt hat.i denotes a well pipe sunk into the ground into which . the water has access from below. In this tube is a drive from an electric motor 2 and a centrifugal pump 3 built-in existing pump set, one of which is the pipe i top cover q. is carried, on which it is carried by means of a rope 5 is suspended. The length of this rope can be changed if necessary can be made so that the pump set 2, 3 in the pipe i is set to any desired height can be. 6 denotes a cable that is used to feed the for driving the motor 2 required current is used. The pump 3 has -a suction basket 7, an impeller 8, a diffuser channel 9 and a throttle point io, which in connection with Channels i i is used to compensate for the axial thrust of the pump. The pump 3 promotes directly into the pipe i, the seal between the suction chamber 12 and the Pressure chamber 13 of this Rdhres is caused by the pump itself by using a compliant seal 1 ¢ is provided, which is attached to the inner wall of the tube i tightly connected, but the possibility of setting the pump set 2, 3 in the pipe i in no way affected. The seal 1 [has an annular recess 15 to which the pressurized water has access.
Da das Rohr i nach oben abgeschlossen ist, dient der Druckraum 13 gleichzeitig als Windkessel, wobei Rückschlagventile 16 bei stillstehender Pumpe das Überströmen von Wasser aus dem Druckraum 13 in den Saugraum 12 verhindern. In den Raum 13 ragt ein an die Verbrauchsleitung 17 angeschlossenes Rohr 18, das nahezu bis zur Pumpe 3 hinabreicht. i9 ist ein Rohr, durch das Luft oder ein Gas ein- oder abgeführt werden kann. Bei der beschriebenen Pumpeneinrichtung ist kein besonderer Windkessel erforderlich, und es sind keine unmittelbaren Rohranschlüsse an den senk- und hebbaren Pumpensatz 2, 3 zu bewirken.Since the tube i is closed at the top, the pressure chamber 13 is used at the same time as an air vessel, with check valves 16 when the pump is at a standstill prevent the overflow of water from the pressure chamber 13 into the suction chamber 12. In the space 13 protrudes a pipe 18 connected to the consumption line 17, which is almost reaches down to pump 3. i9 is a pipe through which air or a gas enters or can be discharged. In the case of the pump device described, there is no special one Air chambers are required and there are no direct pipe connections to the and liftable pump set 2, 3 to effect.
Die Pumpe 3 kann auch mehrstufig ausgeführt werden. Um die Abdichtung des Motors 2 gegen einen eventuellen Wassereintritt zu erleichtern, kann der Raum 2o zwischen Pumpe 3 und Motor 2 mit den Kanälen i i, wie veranschaulicht, und durch diese andererseits mit dem Saugraum 12 in Verbindung gesetzt werden.The pump 3 can also be designed in several stages. To the waterproofing of the motor 2 to prevent the ingress of water, the space 2o between pump 3 and motor 2 with the channels i i, as illustrated, and through on the other hand, these are connected to the suction chamber 12.
Die Erfindung kann außer bei Brunnenpumpen auch bei Bohrlochpumpen u. dgl. zur Anwendung kommen.In addition to well pumps, the invention can also be used with borehole pumps and the like are used.
