Gegenstand vorliegender Erfindung bildet eine elektrisch angetriebene Abteufpuinpe, bei welcher der Elektromotor direkt mit der Centrifugalpumpe gekuppelt ist. Hierdurch wird der Vortheil erreicht, dafs man wegen des Fortfalles jeder Uebersetzung Motoren mit grofser Umlaufsgeschwindigkeit, also verhaltnifsniafsig kleine und leichte Motore verwenden kann, wahrend ferner die Pumpe durch den senkrechten Uebereinanderbau des Pumpenkörpers und Elektromotors wenig Raum im AbteuFschacht einnimmt.The present invention forms an electrically driven sinking pump which the electric motor is coupled directly to the centrifugal pump. This will the advantage is achieved that, because of the elimination of any gear ratio, motors are also used high orbital velocity, so relatively moderate can use small and light motors, while furthermore the pump through the vertical stacking of the pump body and electric motor takes up little space in the sinking shaft.
Auf beiliegender Zeichnung ist der Erfindungsgegenstand dargestellt. The subject of the invention is shown in the accompanying drawing.
Wie ersichtlich, wird der untere Theil der Abteufpumpe durch den eigentlichen Pumpenkörper α gebildet, der an ein Zwischengehäuse b angehängt ist, welch' letzteres die Kupplung c und den Collector d bei Gleichstrommotoren bezw. die Schleifringe bei Dreh- oder Wechselstrommotoren einschliefst.As can be seen, the lower part of the sinking pump is formed by the actual pump body α , which is attached to an intermediate housing b , which 'the latter the coupling c and the collector d respectively in DC motors. includes the slip rings in three-phase or AC motors.
In der oberen Hälfte dieses Gehäuses b befinden sich mehrere Oeffnungen, damit man die Stromzuführungsbürsten bequem bedienen kann. Um dem Eindringen des Wassers vorzubeugen, werden diese Oeffnungen mit Thüren verschlossen, die am Umfang mit einer dicht anschliefsenden Gummieinlage versehen sind.In the upper half of this housing b there are several openings so that the power supply brushes can be conveniently operated. In order to prevent the penetration of water, these openings are closed with doors, which are provided with a tightly fitting rubber insert on the circumference.
C ist das Magnetgestell des Motors, auf welchem der Deckel f ruht, der gleichzeitig das obere Führungslager g tragt. Nach oben hin ist dieses Lager durch einen wasserdicht schliefsenden Deckel abgedichtet, in welchem das Rohr Afür die Schmierölzuführung eingeschraubt,wird. C is the magnetic frame of the motor on which the cover f rests, which at the same time supports the upper guide bearing g. This bearing is sealed at the top by a water-tight closing cover, into which the tube A for the lubricating oil supply is screwed.
Die Schmierung summtlicher Lager erfolgt durch dieses Rohr, und zwar wird das durch das obere Lager g hindurchgeflossene OeI zu dem mittleren Lager i geführt und fliefst dann durch die in der Längsrichtung durchbohrte Kupplung c in das Kugellager Λ, welches das Ge- ' wicht sämmtlicher umlaufender Theile tragt. An Stelle dieses Kugellagers kann die Pumpe auch mit einem Spurlager versehen werden, welches an dem #unteren Theil des Pumpen- ' körpers anzubringen ist.The lubrication of all bearings takes place through this tube, namely the oil that has flown through the upper bearing g is led to the middle bearing i and then flows through the coupling c , which is pierced in the longitudinal direction, into the ball bearing Λ, which carries the weight of the entire circumference Parts. Instead of this ball bearing, the pump can also be provided with a thrust bearing, which is to be attached to the lower part of the pump body.
Sammtliche Centrirungsflantschen des aufseren > Pumpenmantels sind sauber eingepackt und durch dünne Oelpapierzwischenlagen abgedichtet, so dafs während eines normalen Betriebes das Eindringen von Wasser ,ausgeschlossen ist. ,All the centering flanges of the external> The pump casing is neatly packed and sealed with thin oil paper interlayers, so that the penetration of water is excluded during normal operation is. ,
Um für den Fall, dafs durch rapid steigen-' ' des Wassei die Pumpe zum Ersaufen kommen sollte und sich dann durch irgend eine undicht gewordene Stelle Wasser in dem Inneren des Gehäuses ansammelt, den Betlieb trotzdem aufrecht erhalten zu können, ist auf dem obeien Deckel f ein_Rohr_Ar angebracht, .welches mit , einer Kohlensjureflasche_ oder eineni_ Behälter mit^ compnmTrter "Luft in Verbindung stellt". < In dem unteren Theile α des'Piunpenkörpers (, befindet sich für diesen Fall ein% Ventil, das , sich so lange öffnet und das eingedrungene Wasser abfliefsen Iäfst, als der Ueberdruck gegen die äufsere Wassersäule, der durch das Einlassen der Kohlensäure bezw. der compiimirten Luft in das Innere des Gehäuses hervorgerufen wird, andauert. ' ' ' In order to be able to maintain the bed in spite of the fact that the pump should drown due to the rapid rise in the water and water then collects in the interior of the housing through some leak which has become a leak, is on the top cover For a_pipe_Ar attached, .which "puts air in contact" with, a coal bottle_ or a container with ^ compnmTrter. <Α In the lower part des'Piunpenkörpers (, is in this case a% valve which opens so long and the penetrated water abfliefsen Iäfst when the excess pressure against the outward water column, the BEZW by the admission of the carbon dioxide. Of compressed air into the interior of the housing persists. '''
