Claims (12)

1. Scrollpumpe zur Förderung von Gasen oder Gas-Kondensat- Gemischen mit einem Einlass (8), einem Auslass (9), einer feststehenden Statorscheibe (2) und einer drehbaren Rotor­ scheibe (3), die auf einer Antriebswelle (4) befestigt ist, wobei diese Scheiben (2, 3) im wesentlichen parallel zueinander liegen und jeweils spiralförmig verlaufende Flanken (6) tragen, die unter Bildung von veränderlichen Förderräumen (7) ineinander eingreifen, dadurch gekenn­ zeichnet, dass die Antriebswelle (4) im Betriebszustand im wesentlichen vertikal angeordnet ist, so dass die Scheiben (2, 3) im wesentlichen horizontal liegen, dass der Auslass (9) vom Zentrum der unten liegenden Scheibe ausgeht und so nach außen geführt ist, dass ggf. anstehendes Kondensat aufgrund der Schwerkraft abfließt.1. Scroll pump for conveying gases or gas-condensate mixtures with an inlet ( 8 ), an outlet ( 9 ), a fixed stator disc ( 2 ) and a rotatable rotor disc ( 3 ) which is attached to a drive shaft ( 4 ) , These disks ( 2 , 3 ) are essentially parallel to each other and each carry spirally extending flanks ( 6 ) which engage in each other to form variable delivery spaces ( 7 ), characterized in that the drive shaft ( 4 ) essentially in the operating state is arranged vertically, so that the panes ( 2 , 3 ) lie essentially horizontally, that the outlet ( 9 ) starts from the center of the pane below and is guided outwards so that any condensate present flows away due to gravity. 2. Scrollpumpe nach Anspruch 1, dadurch gekennzeichnet, dass in den Auslass (9) kein die druckfreie Abgabe des Gases bzw. Kondensats behinderndes Ausgangsventil eingeschaltet ist.2. Scroll pump according to claim 1, characterized in that in the outlet ( 9 ) none of the pressure-free delivery of the gas or condensate hindering output valve is switched on. 3. Scrollpumpe nach Anspruch 1 oder 2, dadurch gekennzeich­ net, dass an dem freien Ende der spiralförmig verlaufenden Flanken (6) jeweils eine Dichtung (11) angebracht ist, welche zur Abdichtung der Förderräume (7) an der gegen­ überliegenden Scheibe anliegt. 3. Scroll pump according to claim 1 or 2, characterized in that a seal ( 11 ) is attached to the free end of the spiraling flanks ( 6 ), which rests for sealing the delivery spaces ( 7 ) on the opposite disc. 4. Scrollpumpe nach Anspruch 3, dadurch gekennzeichnet, dass die Dichtung (11) in eine stirnseitige Nut (12) in den Flanken (6) eingelegt ist und in axialer Richtung gering­ fügig über die Flanken (6) hinausragt, so dass zwischen der Dichtung (11) und dem Fuß des benachbarten Flankenab­ schnitts unter allen Betriebsbedingungen ein minimaler Kanal (13) verbleibt, der den Abfluss von Kondensat zum Auslass (9) gestattet.4. Scroll pump according to claim 3, characterized in that the seal ( 11 ) is inserted into an end groove ( 12 ) in the flanks ( 6 ) and slightly projects in the axial direction over the flanks ( 6 ), so that between the seal ( 11 ) and the foot of the adjacent flank section under all operating conditions, a minimal channel ( 13 ) remains, which allows the condensate to drain to the outlet ( 9 ). 5. Scrollpumpe nach Anspruch 4, dadurch gekennzeichnet, dass die Dichtung (11) auch eine Abdichtung der Förderräume (7) gegenüber den Lagern und Gehäuseteilen (1) bewirkt.5. Scroll pump according to claim 4, characterized in that the seal ( 11 ) also seals the delivery spaces ( 7 ) with respect to the bearings and housing parts ( 1 ). 6. Scrollpumpe nach Anspruch 5, dadurch gekennzeichnet, dass die Dichtung (11) so angeordnet ist, dass zusätzliche Dichtungen an bewegten Bauteilen zur Abdichtung des Förderraums (7) nicht erforderlich sind.6. Scroll pump according to claim 5, characterized in that the seal ( 11 ) is arranged such that additional seals on moving components for sealing the delivery chamber ( 7 ) are not required. 7. Scrollpumpe nach einem der Ansprüche 3 bis 6, dadurch gekennzeichnet, dass die Dichtung (11) ein Dichtungsband aus Teflon, Graphit und Gummi ist.7. Scroll pump according to one of claims 3 to 6, characterized in that the seal ( 11 ) is a sealing tape made of Teflon, graphite and rubber. 8. Scrollpumpe nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, dass die Rotorscheibe (3) oberhalb der Statorscheibe (2) angeordnet ist.8. Scroll pump according to one of claims 1 to 7, characterized in that the rotor disc ( 3 ) above the stator disc ( 2 ) is arranged. 9. Scrollpumpe nach einem der Ansprüche 1 bis 8, dadurch gekennzeichnet, dass die Antriebswelle (4) einstückig mit der Abtriebswelle eines elektrischen Motors (5) ausgebil­ det ist. 9. Scroll pump according to one of claims 1 to 8, characterized in that the drive shaft ( 4 ) is integrally formed with the output shaft of an electric motor ( 5 ). 10. Scrollpumpe nach einem der Ansprüche 1 bis 9, dadurch gekennzeichnet, dass die Antriebswelle (4) weiterhin ein Lüfterrad (10) trägt, welches Kühlluft an die Scheiben (2, 3) und ggf. an den Motor (5) transportiert.10. Scroll pump according to one of claims 1 to 9, characterized in that the drive shaft ( 4 ) further carries a fan wheel ( 10 ) which transports cooling air to the disks ( 2 , 3 ) and optionally to the motor ( 5 ). 11. Scrollpumpe nach dem auf Anspruch 9 rückbezogenen Anspruch 10, dadurch gekennzeichnet, dass, der Motor (5) oberhalb der Rotorscheibe (3) positioniert ist, die Statorscheibe (2) Bestandteil des Gehäuses (1) der Scrollpumpe ist und das Lüfterrad (10) unterhalb der Statorscheibe (2) an der Antriebswelle (4) befestigt ist.11. The scroll pump according to claim 9, wherein the motor ( 5 ) is positioned above the rotor disk ( 3 ), the stator disk ( 2 ) is part of the housing ( 1 ) of the scroll pump and the fan wheel ( 10 ) is attached to the drive shaft ( 4 ) below the stator disc ( 2 ). 12. Scrollpumpe nach einem der Ansprüche 1 bis 11, dadurch gekennzeichnet, dass in den Einlass (8) kein Eingangsventil eingeschaltet ist.12. Scroll pump according to one of claims 1 to 11, characterized in that no inlet valve is switched on in the inlet ( 8 ).
