摘要:
The invention relates to a collecting tank for multi-phase mixtures from a hydrocarbon source, having at least one inlet (20) for introducing multi-phase mixtures into the collecting tank (10), and having a plurality of outlet connectors (30), which can be connected to pumps (3) via which multi-phase mixtures are pumped, the outlet connectors (30) being assigned inwardly directed internals (40) which project upwards beyond the collecting-tank base (11) and have a first, upper opening (42) and a second, lower opening (41), wherein the flow cross section of the lower opening (41) is smaller than that of the upper opening (42).

The invention relates to a screw displacement pump with a single-entry, double-shaft construction, comprising an outer bearing for both screw shafts (1, 2) and a pump housing (3), enclosing the screw shafts (1, 2) to form pumping chambers (4) and externally defining the pumping chambers (4) with the inner sleeve surface thereof, an induction chamber (5) for the induction medium and a pressure chamber (6), for the medium pumped by means of the screw shafts (1, 2). The pump housing (3) is introduced into a pressure housing (7) and fixed to the pressure housing (7) such that the pressure chamber (6) at least partly encloses the pump housing (3).
摘要:
The aim of the invention is to improve delivery of the multi-phase mixture especially hydrocarbons from a well and to limit the free gas volume. According to the invention, a partial liquid flow (13) is branched off on the pressure side from the main supply flow and is delivered on the high-pressure side to at least one jet pump (2) that is disposed on the suction side (1) as an auxiliary delivery device. The pump installation comprises a feed line (7) linking the pressure chamber of the displacement pump (1) with the high-pressure side of at least one jet pump (2), said jet pump (2) being disposed on the suction side in the direction of delivery of the displacement pump (1).
摘要:
Die Erfindung betrifft eine fluidführende Maschine, insbesondere Pumpe, mit einem in einem stillstehenden Gehäuseteil (16) innerhalb eines Ringspaltes rotierenden Bauteil (8), wobei das stillstehende Gehäuseteil einen höheren Produktdruck aufweisenden Innenraum (11) von einem einen niedrigen Druck aufweisenden Außenraum (18) trennt, in dem das rotierende Bauteil in einer Außenlagerung (13) gelagert ist, die gegenüber dem Innenraum über ein Dichtungssystem abgedichtet ist. Zur Verbesserung der Abdichtung wird erfindungsgemäß vorgeschlagen, daß der Ringspalt (17) zwischen zwei aus extrem harten, verschleißfesten Werkstoffen bestehenden Gleitlagerschalen (19) gebildet ist, die nach dem Wirkprinzip eines Radial-Gleitlagers eine erste Druckabbaustufe bilden, der in axialer Richtung eine die Leckage aus dieser ersten Dichtungsstufe in den Förderprozeß der Maschine zurückführende Rückführeinrichtung (21) nachgeschaltet ist, der in axialer Richtung eine zweite Dichtungsstufe (22) nachgeordnet ist, die als einfache Dichtung in Form eines Lippendichtringes und/oder einer einfachen Gleitringdichtung ausgebildet ist.

Zweiflutige Schraubenspindelmaschine zum Antrieb durch Multiphasengemische oder zum Fördern von Multiphasengemischen mit zumindest zwei getrennten Einlassräumen (11,12) und einem Auslassraum (20) und einem den Einlassräumen (11,12) vorgeschalteten Separator (30) zur Trennung von Flüssigkeitsphase und Gasphase, wobei beide Einlassräume (11,12) mit dem Separator (30) über getrennten Leitungen (31,32;33) für die Gasphase und die Flüssigkeitsphase verbunden sind.
摘要:
The invention relates to a single-flow type two-spindle screw pump comprising an outer bearing (4) for the two spindles (1, 2), a pump housing (3) that encloses at least the two spindles (1, 2) and thereby forms the conveying chambers (11) required for the pumping process, a connection (6) for the conveying medium that is to be aspirated (arrow 7), said connection (6) being located at the inlet end and extending into a suction chamber (5), and a connection (9) for a pressure-delivering line used for the conveying medium that is to be discharged (arrow 10), said connection (9) being connected to a pressure chamber (8). At least one of the two inventive connections (6, 9) is part of a removable inlet connection housing module or outlet connection housing module (13 or 14, henceforth referred to as connection module ) which is flanged to a conveying housing module (12) so as to form a parting line (15, 16). The inner shell surface (12a) of the conveying housing module (12) delimits the outside of the conveying chambers (11). The parting lines (15, 16) between the conveying housing module (12) and the connection module (13, 14) extend perpendicular to the spindle axes (17, 18) through the cross section of the suction chamber (5) or pressure chamber (8).
