Description

Flüssigkeitsringpumpe insbesondere Wasserringpumpe Es ist bereits bekannt. bei Wasseirringpumpen zur Verringerung der Verluste: durch Flüssigkeitsreibung im Pumpengehäuse zwischen dem kreisenden Flüssigkeitsring und dem Gehäuse eine umlaufende Ringtrommel einzuschalten. Diese Ringtrommel weist hierbei im Zylindermantel axial verlaufende Rippen sowie die Hohlräume zwischen den erwähnten Rippen mit den Wasserringraum verbindende Bohrungen auf, die dazu dienen, einen Druckausgleich zu ermöglichen. Trotz dieser Anordnung hat sich gezeigt, daß die erstrebte Wirkung, nämlich die Herabsetzung der Flüssigkeitsreibungsverluste, nicht oder nur höchst unvollkommen .erreicht wird und daß das Anlaufen der zur Verminderung der Flüssigkeit vorgesehenen Ringtrommel infolge der zu großen Reibung zwischen den. Rippen oder Stegen der Ringtrommel und dem äußeren Gehäusemantel nicht sichergestellt ist.Liquid ring pump especially water ring pump It is already known. in water iring pumps to reduce losses: through fluid friction in the pump housing between the rotating liquid ring and the housing a circumferential Turn on the ring drum. This ring drum has here axially in the cylinder jacket running ribs and the cavities between the mentioned ribs with the water annulus connecting holes that serve to enable pressure equalization. Despite this arrangement, it has been shown that the desired effect, namely the Reduction of the fluid friction losses, not at all or only very imperfectly .Achieved and that the start-up of the intended to reduce the liquid Ring drum due to the excessive friction between the. Ribs or webs of the ring drum and the outer casing shell is not ensured.

Gegenstand der Erfindung ist eine Verbesserung derartiger Flüssigkeitsringpumpen mit einer zwischen dem kreisenden Flüssigkeitsring und dem Pumpengehäuse eingeschalteten umlaufenden Ringtrommel. welche sich dadurch auszeichnet, daß dem Spalt zwischen Ringtrommnel und Gehäuse durch Bohrungen, in dem Gehäuse verteilt, eine Druckflüssigkeit zugeführt wird. Durch diese Maßnahme wird eis ermöglicht, die Ringtrommel von vornherein, d. h. schon beim Anfahren, mit wenig radialem Spiel in der Schwebe zu halten, so daß eine besonders geringe Reibung zwischen dem Pumpengehäuse und der den Flüssigkeitsring enfhaltenden Ringtrommel sichergestellt ist. Unter Umständen kann es Vorteile bieten, die Drücke in den einzelnen Drucktaschen zwischen Gehäuse und Ringtrommel verschieden groß zu machen, um einen völligen Druckausgleich zu erhalten.The invention relates to an improvement in such liquid ring pumps with one connected between the rotating liquid ring and the pump housing revolving ring drum. which is characterized in that the gap between Ring drum and housing through bores, distributed in the housing, a pressure fluid is fed. This measure makes it possible to use the ring drum from the start, d. H. already when starting, to keep it in suspension with little radial play, like that that a particularly low friction between the pump housing and the liquid ring enfhaltenden ring drum is ensured. Under certain circumstances it can offer advantages the pressures in the individual pressure pockets between the housing and the ring drum differ to make it large in order to obtain a complete pressure equalization.

Im folgenden soll die Erfindung näher an Hand eines Ausführungsbeispiels erläutert werden, das in den Fig. 1 und 2 der Zeichnung wiedergegeben ist.In the following, the invention will be described in more detail by means of an exemplary embodiment will be explained, which is shown in Figs. 1 and 2 of the drawing.

1 bedeutet: das Pumpengehäuse, 2 das Pumpenrad, das exzentrisch zur Bohrung des Pumpengehäuses liegt und von einem in der Figur nicht wiedergegebenen Motor angetrieben ist. Zwischen der Bohrung des Pumpengehäuses 1 und dem Pumpenläufer 2 ist eine Ringtrommel 3 vorgesehen, die zur Verringerung der Flüssigkeitsreibung beim Betrieb durch den umlaufenden Wasserring mitgenommen werden soll. Erfindungsgemäß wird nun. durch Bohrungen 8 des Gehäuses, welche in die Drucktaschen 9 einmünden, in den Spalt zwischen Ringtrommel 3 und Gehäuse 1 eine Druckflüssigkeit eingeführt, die die Ringtrommel so in der Schwebe: hält, daß ein Anliegen der metallischen Ringtrommel an der Innenfläche des Gehäuses vermieden. wird und daher der Bewegungswiderstand der Ringtrommel außerordentlich gering gehalten wird. Im Zusammenhang mit der erfindungsgemäßen Lösung ist es von Bedeutung, daß sowohl die Ringtrommel wie das Gehäuse auf ihrer Oberfläche genau bearbeitet sind und eine saubere und glatte Oberfläche aufweisen. Um die! Bewegungswiderstände besonders klein zu halten, kann es vorteilhaft sein, wenigstens einen der Teile mit einem Gleitbelag, z. B. Gummibelag, zu versehen. Unter Umständen kann es auch Vorteile bieten, die Ringtrommel 3 statt aus Metall aus Gummi oder einem Kunststoff herzustellen. der sich durch eine glatte Oberfläche auszeichnet.1 means: the pump housing, 2 the pump wheel, which is eccentric to the Bore of the pump housing is and of a not shown in the figure Motor is driven. Between the bore of the pump housing 1 and the pump rotor 2, a ring drum 3 is provided, which is used to reduce the fluid friction should be taken through the surrounding water ring during operation. According to the invention will now. through holes 8 of the housing which open into the pressure pockets 9, a hydraulic fluid is introduced into the gap between the ring drum 3 and the housing 1, which keeps the ring drum in suspension so that the metallic ring drum comes into contact avoided on the inner surface of the housing. becomes and therefore the resistance to movement the ring drum is kept extremely low. In connection with the invention Solution, it is important that both the ring drum and the housing on their Surface are precisely machined and have a clean and smooth surface. To the! To keep movement resistance particularly small, it can be advantageous to at least one of the parts with a sliding coating, e.g. B. rubber covering to be provided. Under certain circumstances it can also offer advantages, the ring drum 3 instead of metal made of rubber or a plastic. which is characterized by a smooth surface excels.
