Description
Die Erfindung betrifft eine Ölförder- und Vakuumpumpe mit einem Pumpengehäuse, einem im Pumpengehäuse drehbar gelagerten Rotor, einem im Rotor verschieblich gelagerten Flügel, dessen Flügelspitzen an der Innenumfangswand eines Pumpenraums anliegen und diesen in einen Saugraum und einen Druckraum unterteilen, wobei sich der Flügel quer zur Drehachse des Rotors erstreckt, und mit einem in den Saugraum mündenden Einlass und einem vom Druckraum ausmündenden Auslass.The The invention relates to a Ölförder- and Vacuum pump with a pump housing, one in the pump housing rotatably mounted rotor, a displaceably mounted in the rotor Wing, its wing tips abut against the inner peripheral wall of a pump room and this in subdivide a suction chamber and a pressure chamber, with the wing across extends to the axis of rotation of the rotor, and with a in the suction chamber opens Inlet and an outlet opening out from the pressure chamber.
Es sind Vakuumpumpen bekannt, bei denen in einem Pumpengehäuse ein Rotor exzentrisch angeordnet ist, mit welchem ein Flügel in einem Pumpenraum gedreht wird. Der Flügel berührt mit seinen Flügelspitzen die Innenumfangsfläche beziehungsweise Innenumfangswand des Pumpenraums und wird dabei im Rotor oszillierend verschoben. Derartige Flügelzellenpumpen besitzen den wesentlichen Vorteil, dass sie einfach aufgebaut sind und ein geringes Gewicht aufweisen. Der im Pumpenraum gebildete Saugraum besitzt einen Einlass, welcher axial angeordnet ist und der im Pumpenraum gebildete Druckraum besitzt einen Auslass, welcher in der Innenumfangswand des Pumpenraums liegt und ein Rückschlagventil aufweist.It Vacuum pumps are known in which in a pump housing a Rotor is arranged eccentrically, with which a wing in one Pump room is rotated. The wing touched with his wing tips the inner peripheral surface or inner peripheral wall of the pump chamber and is doing oscillated in the rotor. Such vane pumps have the significant advantage that they are simple and a low Have weight. The suction chamber formed in the pump chamber has an inlet which is arranged axially and in the pump room formed pressure chamber has an outlet which in the inner peripheral wall the pump chamber is located and a check valve having.
Der Erfindung liegt die Aufgabe zugrunde, eine Ölförder- und Vakuumpumpe bereitzustellen, mit welcher nicht nur Gase, sondern auch Flüssigkeiten gefördert werden können, wobei die Pumpe einerseits einen kleinen Bauraum aufweist, andererseits ein hohes Ölfördervolumen besitzt, einfach aufgebaut ist und zudem eine geringe Verlustleistung aufweist.Of the Invention has for its object to provide an oil feed and vacuum pump, with which not only gases, but also liquids are conveyed can, wherein the pump on the one hand has a small space, on the other hand a high oil delivery volume own, is simple and also a low power loss having.
Diese Aufgabe wird erfindungsgemäß mit einer Ölförder- und Vakuumpumpe der eingangs genannten Art gelöst, wobei der Einlass und der Auslass in der Innenumfangswand des Pumpenraums angeordnet sind.These Task is inventively with a Ölförder- and Vacuum pump of the type mentioned, wherein the inlet and the Outlet in the inner peripheral wall of the pump chamber are arranged.
Bei der erfindungsgemäßen Ausgestaltung der Ölförder- und Vakuumpumpe liegen der Einlass und der Auslass in radialer Richtung, was den wesentlichen Vorteil hat, dass das Öl nur geringe Umlenkungen erfährt, also nicht von einer axialen Anströmrichtung in eine radiale Richtung oder Umfangsrichtung umgelenkt werden muss, sondern radial in den Pumpenraum einströmt und aus diesem wieder radial ausströmt. Bei Pumpen, mit welchen Gase gefördert werden, spielt dieser Aspekt eine untergeordnete Rolle, da Gase eine relativ geringe Masse aufweisen. Bei Flüssigkeiten ist dieser Aspekt nicht mehr vernachlässigbar, sondern spielt eine entscheidende Rolle, da axial anströmende Flüssigkeiten vom Flügel beschleunigt werden müssen, was zusätzliche Energie erfordert.at the inventive design of Ölförder- and Vacuum pump are the inlet and the outlet in the radial direction, which has the significant advantage that the oil experiences only minor deflections, ie not from an axial flow direction must be deflected in a radial direction or circumferential direction, but radially into the pump chamber flows and from this again radially flows. For pumps with which gases are conveyed this aspect plays a minor role as gases have a relatively low mass. For liquids, this aspect is not more negligible, but plays a crucial role as axially inflowing liquids from the wing have to be accelerated something extra Energy requires.
Erfindungsgemäß weist der Flügel eine konstante Länge auf. Dies hat den Vorteil, dass der Flügel zum einen einfach herstellbar ist, zum anderen die Montage einfach erfolgen kann, da der Flügel nicht aus mehreren Bauteilen, zum Beispiel Flügelkörper mit Flügelspitzen und gegebenenfalls dazwischen angeordneten Federmitteln, aufgebaut ist. Der Flügel kann selbstverständlich in Form einer Fachwerkstruktur mit in Längsrichtung des Flügels und/oder parallel zur Drehachse verlaufenden Kanälen oder Einsenkungen versehen sein. Hierdurch wird Gewicht eingespart, wodurch die Trägheitskräfte verringert können und der Flügel mit geringerem Kraftaufwand beschleunigt und verzögert werden kann. Auf diese Weise wird die Abnutzung der Flügelspitzen verringert.According to the invention the wing a constant length on. This has the advantage that the wing for a simple to produce On the other hand, the assembly can be done simply because the wing is not of several components, for example, wing body with wing tips and possibly arranged therebetween spring means, is constructed. The wing can Of course in the form of a truss structure with in the longitudinal direction of the wing and / or provided parallel to the axis of rotation extending channels or depressions be. As a result, weight is saved, which reduces the inertial forces can and the wing can be accelerated and decelerated with less effort. In this way, the wear of the wing tips is reduced.
Bei einer Ausführungsform liegen der Einlass und der Auslass in der gleichen Querschnittsebene. Eine andere, alternative Ausführungsform sieht vor, dass der Einlass und der Auslass axial versetzt zueinander angeordnet sind. Hierdurch kann unterschiedlichen Anschlussarten für zuführende und abführende Leitungen Rechnung getragen werden, da diese Leitungen an der Außenseite des Pumpengehäuses angeordnet werden müssen.at an embodiment the inlet and the outlet are in the same cross-sectional plane. Another alternative embodiment sees in that the inlet and the outlet are axially offset from each other are arranged. This allows different connection types for feeding and laxative Lines are taken into account, as these lines are on the outside of the pump housing must be arranged.
Mit Vorzug weisen der Einlass und der Auslass in radialer Richtung verlaufende Wandflächen auf. Dies bedeutet, dass der Einlass und der Auslass sich innerhalb der Wand des Pumpengehäuses in radialer Richtung nach außen aufweiten. Auf diese Weise werden Strömungsverluste verringert.With Advantageously, the inlet and the outlet extending in the radial direction Wall surfaces on. This means that the inlet and the outlet are within the Wall of the pump housing in the radial direction to the outside expand. In this way flow losses are reduced.
Bei einem bevorzugten Ausführungsbeispiel ist vorgesehen, dass das Pumpengehäuse zwei Pumpenräume aufweist und jeder Pumpenraum mit einem Gehäusedeckel verschließbar ist. In jedem der Pumpenräume ist ein Rotor mit einem Flügel angeordnet, wodurch die Saug- oder Volumenleistung der Ölförderpumpe erhöht, insbesondere verdoppelt, wird.at a preferred embodiment provided that the pump housing two pump rooms and each pump chamber is closable with a housing cover. In each of the pump rooms is a rotor with a wing arranged, whereby the suction or volume capacity of the oil feed pump elevated, especially doubled, will.
Bei einer Weiterbildung wird im einen Pumpenraum Öl oder Öl-Gas-Gemisch und im anderen Pumpenraum ein Gas gefördert, insbesondere abgesaugt.at a training is in a pump room oil or oil-gas mixture and in the other pump room promoted a gas, sucked in particular.
Bei einem Ausführungsbeispiel wird der Rotor von zwei, insbesondere axial hintereinander angeordneten Rotorabschnitten gebildet, wobei jeder Rotorabschnitt in einen der beiden Pumpenräume eingesetzt ist. Diese Ausgestaltung besitzt den Vorteil, dass lediglich ein einziger Antrieb erforderlich ist, und mit diesem Antrieb beide Rotorabschnitte angetrieben werden. Eine derartige Ölförder- und Vakuumpumpe ist leicht regelbar und besitzt ein hohes Fördervolumen. Dabei können die Pumpenräume gleich oder unterschiedliche Volumen aufweisen.at an embodiment the rotor is arranged by two, in particular axially one behind the other Rotor sections formed, each rotor section in one of used in both pump rooms is. This embodiment has the advantage that only one single drive is required, and with this drive both Rotor sections are driven. Such Ölförder- and Vacuum pump is easily adjustable and has a high flow rate. It can the pump rooms the same or have different volumes.
Erfindungsgemäß ist ein Rotorabschnitt mit einem zapfenförmigen axialen Ende und der andere Rotorabschnitt mit einem axialen hülsenförmigen Ende versehen, wobei das eine Zapfenende in das andere Hülsenende eingesteckt ist. Hierdurch wird nicht nur eine einfache Lagerung geschaffen, sondern es werden auch axiale Toleranzen ausgeglichen, insbesondere axiale Lagetoleranzen der beiden Pumpenräume bezüglich der beiden Rotorabschnitte.According to the invention is a Rotor section with a cone-shaped axial end and the other rotor portion with an axial sleeve-shaped end provided, wherein the one end of the spigot in the other end of the sleeve is plugged in. This is not just a simple storage created, but also axial tolerances are compensated, in particular axial position tolerances of the two pump chambers with respect to two rotor sections.
Eine einfache Lagerung wird dadurch geschaffen, dass das Hülsenende des einen Rotorabschnitts im Pumpengehäuse, insbesondere in der Trennwand zwischen den beiden Pumpenräumen, gelagert ist. Dabei bildet auch das Hülsenende des einen Rotorabschnitts das Lager für das Zapfenende des anderen Rotorabschnitts. Eine Schmierung dieser Lager erfolgt vorteilhafterweise über das zumindest von einem der beiden Pumpenräume geförderte Schmieröl.A easy storage is created by the fact that the sleeve end of a rotor section in the pump housing, in particular in the partition wall between the two pump rooms, stored is. This also forms the end of the sleeve one rotor section the bearing for the journal end of the other Rotor section. Lubrication of these bearings is advantageously carried out over the at least one of the two pump rooms promoted lubricating oil.
Eine einfache Drehkopplung der beiden Rotorabschnitte erfolgt erfindungsgemäß dadurch, dass die beiden Enden der Rotorabschnitte über ein Vielkeilprofil, eine Nut-Feder-Verbindung oder ein Polygonprofil miteinander verbunden sind. Hierdurch wird gewährleistet, dass die beiden Rotorabschnitte in Drehrichtung miteinander gekoppelt sind, in axialer Richtung jedoch gegeneinander verschoben werden können. Hierdurch können herstellungsbedingtes Spiel, temperaturbedingte Längenänderungen des Rotors und des Pumpengehäuses und dergleichen ausgeglichen werden.A simple rotational coupling of the two rotor sections takes place according to the invention by that the two ends of the rotor sections via a splined profile, a Tongue and groove or a polygon profile are connected together. This will ensure that the two rotor sections are coupled together in the direction of rotation are, in the axial direction, however, can be moved against each other. hereby can production-conditioned game, temperature-related changes in length of the rotor and the pump housing and the like are compensated.
Die beiden Pumpengehäuse können seriell oder parallel geschaltet werden. Hierdurch kann die Pumpe hinsichtlich des Fördervolumens und des Saugdrucks den geforderten Bedingungen angepasst werden. Insbesondere ist bei einer seriellen Schaltung der nachfolgende Pumpenraum größer als der vorhergehende Pumpenraum.The two pump housings can be connected in series or in parallel. This allows the pump in terms of funding volume and the suction pressure to the required conditions. In particular, in a serial circuit, the following Pump room larger than that previous pump room.
Vorzugsweise sind die beiden Pumpenräume im Pumpengehäuse axial hintereinander angeordnet und werden gleichzeitig vom Rotor axial durchsetzt. Diese Ausgestaltung bietet den wesentlichen Vorteil, dass die Pumpen die oben genannten Eigenschaften besitzt und dass sie zudem schnell und einfach montierbar ist, was insbesondere maschinell erfolgen kann.Preferably are the two pump rooms in the pump housing arranged axially one behind the other and are simultaneously from the rotor axially interspersed. This embodiment offers the significant advantage that the pumps have the above properties and that It is also quick and easy to install, which is especially machine can be done.
Vorteilhaft liegt zwischen den beiden Pumpenräumen eine Gehäusewand, in welcher zumindest einer der Rotorabschnitte gelagert ist. Diese Gehäusewand bildet den Boden für beide Pumpenräume, wobei jeder Pumpenraum von einem eigenen, separaten Deckel verschlossen wird.Advantageous lies between the two pump chambers a housing wall, in which at least one of the rotor sections is mounted. These housing wall forms the ground for both pump rooms, each pump chamber is closed by its own separate lid becomes.
Mit Vorzug sind die Rotorabschnitte in Drehrichtung um 90° versetzt in die Rotorräume eingesetzt. Hierdurch wird das Pumpgeräusch der Ölförder- und Vakuumpumpe beträchtlich verringert und das Pulsieren der Ölförder- und Vakuumpumpe wird auf ein Minimum herabgesetzt. Außerdem ist die Leistungsaufnahme der Pumpe wesentlich gleichmäßiger.With Preference is the rotor sections in the direction of rotation offset by 90 ° in the rotor chambers used. As a result, the pumping noise of the oil pump and vacuum pump is considerable decreases and the pulsation of the oil feed and vacuum pump is on a minimum lowered. Furthermore The power consumption of the pump is much more even.
Mit Vorzug sind der Einlass und der Auslass der Ölförder- und Vakuumpumpe ventilfrei, so dass hierdurch ebenfalls Leistungsverluste verringert werden.With The inlet and the outlet of the oil feed and vacuum pump are preferably valve-free, so that this also reduces power losses.
