Description
Die Erfindung betrifft eine Strömungspumpe mit einem Gehäuse sowie einem innerhalb eines Pumpenraums des Gehäuses rotierend angetriebenen Pumpenrad.The invention relates to a flow pump with a housing and a pump wheel driven in rotation within a pump chamber of the housing.
Eine solche Strömungspumpe ist beispielsweise in der
Die Pumpwirkung einer Strömungspumpe, wie sie Gegenstand des Oberbegriffs des Patentanspruchs 1 ist, beruht darauf, dass eine Flüssigkeit durch einen in der Regel axial bezüglich eines Pumpenrads angeordneten Einlass in einen von einem Gehäuse der Strömungspumpe ausgebildeten Pumpenraum eingebracht wird. Die Flüssigkeit wird dann von dem Pumpenrad, das regelmäßig mit einer Vielzahl von dreidimensional gekrümmt ausgebildeten Schaufeln ausgebildet ist, erfasst und in eine kreisförmige Bewegung beschleunigt. Die dadurch auf die Flüssigkeit einwirkende Zentrifugalkraft beschleunigt diese radial nach außen in einen das Pumpenrad umgebenden Abschnitt des Pumpenraums, von dem dieses durch einen oder mehrere Auslässe abgeführt wird.The pumping action of a flow pump, as it is the subject of the preamble of claim 1, based on the fact that a liquid is introduced through a generally axially arranged with respect to an impeller inlet into a pump housing formed by a housing of the flow pump. The liquid is then captured by the impeller, which is regularly formed with a plurality of three-dimensionally curved blades, and accelerated in a circular motion. The thus acting on the liquid centrifugal force accelerates this radially outwardly into a pump wheel surrounding portion of the pump chamber, from which this is discharged through one or more outlets.
Im Automobilbau kommen solche Strömungspumpen, die auch als Kreiselpumpen bezeichnet werden, beispielsweise als Pumpen für Kühlmittel zum Einsatz. Strömungspumpen, die für diese Anwendung ausgelegt sind, erreichen einen Wirkungsgrad von in der Regel nicht mehr als 40%.In automotive such flow pumps, which are also referred to as centrifugal pumps, for example, as pumps for coolant used. Flow pumps designed for this application typically achieve efficiencies of not more than 40%.
Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, eine verbesserte gattungsgemäße Strömungspumpe anzugeben. Insbesondere sollte sich die erfindungsgemäße Strömungspumpe durch einen hohen Wirkungsgrad auszeichnen.Based on this prior art, the present invention seeks to provide an improved generic flow pump. In particular, the flow pump according to the invention should be characterized by a high degree of efficiency.
Diese Aufgabe wird durch eine Strömungspumpe gemäß dem unabhängigen Patentanspruch 1 gelöst. Vorteilhafte Ausführungsformen der erfindungsgemäßen Strömungspumpe sind Gegenstand der abhängigen Patentansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.This object is achieved by a flow pump according to independent claim 1. Advantageous embodiments of the flow pump according to the invention are the subject of the dependent claims and will become apparent from the following description of the invention.
Eine gattungsgemäße Strömungspumpe mit einem Gehäuse sowie einem innerhalb eines Pumpenraums des Gehäuses rotierend angetriebenen Pumpenrad ist erfindungsgemäß dadurch gekennzeichnet, dass eine oder mehrere, dem Pumpenraum in Strömungsrichtung vorgelagerten, nicht mit dem Pumpenrad (mit gleicher Rotationsgeschwindigkeit) mitrotierende, vorzugsweise fest bezüglich des Gehäuses stehende Leitschaufeln vorgesehen sind.A generic flow pump with a housing and a pump chamber of the housing rotatably driven impeller according to the invention is characterized in that one or more, the pump chamber upstream in the flow direction, not with the impeller (at the same rotational speed) co-rotating, preferably fixed relative to the housing stationary vanes are provided.
Durch die erfindungsgemäße Anordnung der Leitschaufeln kann die Strömung des in das Pumpenrad eintretenden und/oder aus diesem austretenden Fluid positiv beeinflusst werden, wodurch sich im Ergebnis ein höherer Wirkungsgrad der Strömungspumpe erzielen lässt.The inventive arrangement of the guide vanes, the flow of the entering and / or exiting from the impeller fluid can be positively influenced, which can be achieved as a result, a higher efficiency of the flow pump.
Eine positive Beeinflussung des Wirkungsgrads der Strömungspumpe ist insbesondere dann zu erreichen, wenn die Leitschaufeln auf der Niederdruckseite des Pumpenraums angeordnet sind, d. h. auf der Seite des Pumpenraums (bezüglich des Pumpenrads), die mit einem Einlass für das Fluid verbunden ist.A positive influence on the efficiency of the flow pump can be achieved in particular if the guide vanes are arranged on the low-pressure side of the pump chamber, i. H. on the side of the pumping space (with respect to the impeller) which is connected to an inlet for the fluid.
Um den Wirkungsgrad der Strömungspumpe zu erhöhen, kann beispielsweise vorgesehen sein, dass die Leitschaufeln derart angeordnet und/oder ausgebildet sind, dass sie ein zu förderndes Fluid in eine Drallbewegung versetzen. Die Drehrichtung der Drallbewegung kann dabei – je nach Ausgestaltung der einzelnen Pumpenschaufeln des Pumpenrads – der Drehrichtung des Pumpenrads entsprechen oder dieser entgegengesetzt sein. Besonders bevorzugt ist, wenn die Umlenkung des Fluids durch die Leitschaufeln derart ist, dass das Fluid die Pumpenschaufeln unter einem möglichst kleinen Winkel anströmt.In order to increase the efficiency of the flow pump, provision may be made, for example, for the guide vanes to be arranged and / or configured in such a way that they set a fluid to be conveyed into a swirling motion. The direction of rotation of the swirl movement can - depending on the design of the individual pump blades of the impeller - correspond to the direction of rotation of the impeller or this be opposite. It is particularly preferred if the deflection of the fluid through the guide vanes is such that the fluid flows against the pump blades at as small an angle as possible.
Als vorteilhaft hat sich erwiesen, wenn die Leitschaufeln in möglichst direkter Nachbarschaft zu dem Pumpenrad angeordnet sind.It has proved to be advantageous if the guide vanes are arranged in the most direct proximity to the impeller.
Vorzugsweise kann vorgesehen sein, dass die Leitschaufeln (einstückig) in das Gehäuse integriert sind. Alternativ können diese auch in Form eines Einsatzes vorgesehen sein, der in oder an dem Gehäuse befestigt wird.Preferably, it can be provided that the guide vanes (integrally) are integrated into the housing. Alternatively, these may also be provided in the form of an insert which is fixed in or on the housing.
Alternativ kann auch vorgesehen sein, die Leitschaufeln und das Pumpenrad zu kombinieren und diese als Einheit in das Gehäuse einzusetzen. Dadurch kann die Montage der erfindungsgemäßen Strömungspumpe vereinfacht werden. Diese Ausgestaltung setzt dabei voraus, dass die in einer Einheit kombinierten Leitschaufeln und das Pumpenrad relativ zueinander rotieren können.Alternatively, it may also be provided to combine the guide vanes and the impeller and to insert them as a unit in the housing. As a result, the assembly of the flow pump according to the invention can be simplified. This embodiment requires that the combined vanes and the impeller can rotate relative to each other in one unit.
