Abstract
Tauchpumpeneinrichtung zur Verwendung in einem Bohrloch mit einer Schnecken- oder Exzenterschneckenpumpe, die mit einem Antrieb in Verbindung steht, dadurch gekennzeichnet, daß zwischen einem langsam umlaufenden Antrieb in direkter Nähe einer Exzenterschneckenpumpe ein axial- und radialkraftaufnehmendes Koppelungsteil sitzt und der Querschnitt des Koppelungsteils und der Pumpe ≤ 100 mm ist.Submersible pump assembly for use in a borehole with a worm or eccentric screw pump, which is connected to a drive, characterized in that that between a slowly rotating drive in the immediate vicinity of an eccentric screw pump an axial and radial force receiving coupling part sits and the cross-section of the coupling part and the pump is ≤ 100 mm.
Description
Die Erfindung betrifft eine Tauchpumpeneinrichtung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a submersible pump device according to the preamble of claim 1.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, eine Tauchpumpeneinrichtung zu fertigen, die in Bohrlöchern kleiner oder gleich 115 mm betrieben werden kann.Of the Invention is based on the object, a submersible pump device to manufacture in wells less than or equal to 115 mm can be operated.
Die Aufgabe ist erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.The Task is according to the invention with the features of claim 1.
Durch die erfindungsgemäße Anordnung ist es möglich, anstelle von Kreiselpumpen, Schnecken- und Exzenterschneckenpumpen einzusetzen, die besser geeignet sind Produkte mit höherer Viskosität, mit höheren Sand- und Paraphinanteilen sowie Anteilen von Gasen zu fördern.By the inventive arrangement Is it possible, instead of centrifugal pumps, worm and eccentric screw pumps which are more suitable are products with higher viscosity, with higher and paraphenic fractions as well as fractions of gases.
Bisher ist es nicht möglich gewesen, Schnecken- und Exzenterschneckenpumpen in bereits vorhandene Bohrungen einzusetzen, die in der Regel keinen größeren Querschnitt als 115 mm aufweisen. Der Einsatz scheiterte stets daran, daß bei der Verwendung von Antrieben mit Drehzahlen von bis zu 3000 U/min Getriebe vor die Pumpe gesetzt werden mußten. Deren Getriebequerschnitt war jedoch so groß, daß sie für diese Bohrungen mit einem Querschnitt unter 115 mm nicht eingesetzt werden konnten, da zum Einsetzen der Pumpe und dem Betrieb der Pumpe eine seitliche Toleranz von mindestens 5–10 mm beidseits benötigt wird, um die Pumpe im unteren Bereich des Bohrlochs plazieren zu können. Bei der Dimensionierung muß auch das elektrische Antriebskabel berücksichtigt werden, das seitlich an der Pumpe bis zum Antrieb am unteren Ende des Pumpenstrangs geführt werden muß. Schnecken- und Exzenterschneckenpumpen können deshalb entsprechend der Erfindung dann zum Einsatz kommen, wenn die Pumpe mit einem langsam umlaufenden Antrieb und mit einer von der Pumpe erzeugten axial und radial kräfteaufnehmenden Koppelung in Form einer Lagereinheit zum Einsatz kommt. Die radialen Kräfte die das Koppelungsteil bewältigen muß, stammen vom exzentrischen Umlauf des Rotors, die axialen Kräfte vom Druck der in diesem Bohrlochbereich auf den Rotor wirkt. Bei der Herstellung eines entsprechenden Koppelungsteils finden beispielsweise Radiallager und Axiallager Einsatz. Bei entsprechenden Lagereinheiten ist die Einhaltung eines Querschnitts von ≤ 100 mm möglich. In einer vorteilhaften Weitergestaltung der Erfindung verfügt die Lagereinheit über einen Kompensator, der einen Druckausgleich aufgrund unterschiedlich auftretender Temperaturen während des Betriebs der Tauchpumpe herbeiführt und damit die Dichtungen beidseits der Lagereinheit schützt.So far it is impossible been, auger and eccentric screw pumps in already existing Use holes that usually no larger cross-section than 115 mm. The use failed always because of the fact that Use of drives with speeds of up to 3000 rpm gearbox before the pump had to be set. Their gear cross section, however, was so large that they are for these holes with a Cross section below 115 mm could not be used because of Inserting the pump and operating the pump has a lateral tolerance from at least 5-10 mm needed on both sides is to place the pump in the lower area of the well can. at the sizing must also the electric drive cable can be considered, the side be guided at the pump to the drive at the lower end of the pump train got to. Helix and Progressing cavity pumps can Therefore, according to the invention are then used when the pump with a slowly revolving drive and with one of the pump generated axial and radial force-absorbing coupling in shape a storage unit is used. The radial forces the master the coupling part must, come from the eccentric rotation of the rotor, the axial forces of Pressure acting on the rotor in this borehole area. In the Production of a corresponding coupling part find, for example Radial bearing and thrust bearing insert. For corresponding storage units it is possible to maintain a cross section of ≤ 100 mm. In an advantageous Further embodiment of the invention, the storage unit has a Compensator, the pressure equalization due to different temperatures while the operation of the submersible pump and thus the seals protects both sides of the storage unit.
In einer weiteren vorteilhaften Gestaltung der Erfindung wird in der Lagereinheit ein ständiger Schmiermittelkreislauf betrieben, der die Axial- und Radiallager mit Schmiermittel versorgt.In a further advantageous embodiment of the invention is in the Storage unit a permanent lubricant circuit operated, which supplies the axial and radial bearings with lubricant.
