Description
Turbinenlaufrad turbine impeller
Die Erfindung betrifft ein Turbinenlaufrad nach dem Oberbegriff des Anspruchs 1.The invention relates to a turbine impeller according to the preamble of claim 1.
Turbinenlaufräder sind in den vielfältigsten Ausführungsformen bekannt. Meistens weisen sie bezüglich der Anström richtung durch das Antriebsmedium schräg angestellte Schaufeln auf, welche mit dem Antriebsmedium beaufschlagt werden und dadurch die Schaufeln in eine Drehbewegung versetzen. Der Nachteil bei einigen bekannten Turbinenlaufrädern ist, dass ihr Wirkungsgrad nicht optimal ist. Ausserdem sind die Einsatzgebiete beschränkt.Turbine impellers are known in the most varied of embodiments. Mostly they have inclined blades with respect to the direction of flow through the drive medium, which are acted upon by the drive medium and thereby set the blades into a rotary movement. The disadvantage of some known turbine impellers is that their efficiency is not optimal. The areas of application are also limited.
Die DE 33 43 752 A1 zeigt ein offenes Laufrad für Strömungsmaschinen, insbesondere für Kreiselpumpen, der eingangs angegebenen Art. Das Turbinenlaufrad ist durch einen Körper gebildet, welcher aus einzelnen Laufradsegmenten zusammengesetzt ist. Diese Laufradsegmente sind an einer gemeinsamen Nabe befestigt. Die Laufradsegmente bestehen jeweils aus einem Laufradwandsegment und einer daran angeformten Schaufel. Die so gebildeten Rinnen verlaufen bezüglich der Drehachse in Anströmrichtung gesehen im wesentlichen kombiniert kreis- oder spiralförmig sowie wendeiförmig. - Der Nachteil bei diesem bekannten offenen Laufrad für Strömungsmaschinen besteht darin, daß aufgrund der zentralen Nabe das Antriebsmedium sehr weit weg von der Drehachse eingespritzt werden muß, so daß der Wirkungsgrad des Turbinenlaufrades nicht optimal ist.DE 33 43 752 A1 shows an open impeller for turbomachines, in particular for centrifugal pumps, of the type specified at the outset. The turbine impeller is formed by a body which is composed of individual impeller segments. These impeller segments are attached to a common hub. The impeller segments each consist of an impeller wall segment and an integrally formed blade. The channels formed in this way run with respect to the axis of rotation, viewed in the direction of the inflow, essentially in a circular, spiral or helical shape. - The disadvantage of this known open impeller for turbomachines is that due to the central hub, the drive medium must be injected very far away from the axis of rotation, so that the efficiency of the turbine impeller is not optimal.
Davon ausgehend liegt der Erfindung die A u f g a b e zugrunde, bei einem Turbinenlaufrad der eingangs angegebenen Art den Wirkungsgrad zu verbessern.Proceeding from this, the invention is based on the objective of improving the efficiency of a turbine impeller of the type specified in the introduction.
Die technische L ö s u n g ist gekennzeichnet durch die Merkmale im Kennzeichen des Anspruchs 1.The technical solution is characterized by the features in the characterizing part of claim 1.
Dadurch ist ein Turbinenlaufrad mit einem hohen Wirkungsgrad sowie mit einem großen Einsatzgebiet geschaffen. Die Grundidee des erfindungsgemäßen Turbinenlaufrades besteht darin, die Schaufeln als Führungskanäle für das Antriebsmedium auszubilden. Die Anzahl der Schaufeln, das Höhen- sowie Breitenverhältnis sowie der Durchmesser sind frei wählbar. Indem die Rinnen von der gemeinsamen Spitze des Körpers des Turbinenlaufrades ausgehen, schafft dies einen langen Bewegungsweg des^ Antriebsmediums, so daß damit ein hoher Wirkungsgrad erzielt wird. Denn mittels der erfindungsgemäßen Ausbildung des Turbinenlaufrades kann das Antriebsmedium zentral oder nahezu zentral eingespritzt werden. Damit werden alle Schaufeln des Turbinenlaufrades beaufschlagt. Auf diese Weise ist eine einfache Regelung der Drehzahl und damit der Leistung über eine oder eventuell mehrere Düsen geschaffen. Das Turbinenlaufrad wird - bei einer einzigen Düse - über die Spitze oder - bei mehreren Düsen - bezüglich der Spitze leicht versetzt angeströmt und gleichzeitig in allen Schaufeln umgelenkt. Dadurch ist immer eine optimale Anströmung gewährleistet, und sämtliche Schaufeln werden mit dem Antriebsmedium beaufschlagt.This creates a turbine impeller with a high degree of efficiency and with a large area of application. The basic idea of the turbine impeller according to the invention is to design the blades as guide channels for the drive medium. The number of blades, the height and width ratio and the diameter are freely selectable. By starting the channels from the common tip of the body of the turbine impeller, this creates a long movement path of the drive medium, so that a high degree of efficiency is achieved. This is because the drive medium can be injected centrally or almost centrally by means of the construction of the turbine impeller according to the invention. This impacts all the blades of the turbine impeller. In this way, a simple control of the speed and thus the power is created via one or possibly several nozzles. The flow of the turbine impeller is - with a single nozzle - via the tip or - with several nozzles - slightly offset with respect to the tip and at the same time deflected in all blades. This ensures an optimal flow and all the blades are pressurized with the drive medium.
Die Weiterbildung gemäß Anspruch 2 hat den Vorteil, dass auf das Turbinenlaufrad ein optimales Drehmoment ausgeübt und somit eine hohe Drehzahl bewirkt wird.The development according to claim 2 has the advantage that an optimal torque is exerted on the turbine impeller and thus a high speed is brought about.
Die Weiterbildung gemäß Anspruch 3 schafft eine optimale Rinnenform, mittels der das Antriebsmedium optimal geführt ist.The development according to claim 3 creates an optimal channel shape, by means of which the drive medium is optimally guided.
Hinsichtlich der bezüglich der Drehachse radialen Erstreckung der Rinnen vergrößert sich deren Breite gemäß der Weiterbildung in Anspruch 4 in Radialrichtung. Alternativ kann sich die Breite der Rinnen nach außen hin vorzugsweise auch verkleinern.With regard to the radial extent of the channels with respect to the axis of rotation, their width increases in the radial direction according to the development in claim 4. Alternatively, the width of the channels can preferably also decrease towards the outside.
Die Weiterbildung gemäß Anspruch 5 schafft eine kompakte Bauform des Turbinenlaufrades, indem ein Großteil des Turbinenlaufradquerschnittes mit Rinnen belegt ist.The development according to claim 5 creates a compact design of the turbine impeller in that a large part of the turbine impeller cross section is covered with channels.
Die Weiterbildung gemäß Anspruch 6 schafft einen optimalen Strömungsverlauf des Antriebsmediums in den Rinnen.The development according to claim 6 creates an optimal flow of the drive medium in the channels.
Eine bevorzugte Weiterbildung des erfindungsgemäßen Turbinenlaufrades schlägt Anspruch 7 vor. Dadurch ist eine Art rotierendes Laufrad mit blumenartig angeordneten Rinnen geschaffen, wobei der Formkörper aus Kunststoff oder Metall hergestellt sein kann. Die Bewegungsenergie des Antriebstrahls wird dabei auf das rotierende Laufrad übertragen und an der an der Unterseite angebrachten Welle abgenommen. Dadurch ergeben sich eine Vielzahl von Eigenschaften und Vorteile. So zeichnet sich dieses Turbinenlaufrad durch geringe Fertigungskosten sowie durch eine kompakte und kleine Bauweise aus. Außerdem ist das Turbinenlaufrad sehr robust. Schließlich besteht keine Kavitation, und die Gefahr einer Verstopfung durch Treibgut ist nicht gegeben.A preferred development of the turbine impeller according to the invention proposes claim 7. This creates a type of rotating impeller with flower-like troughs, wherein the molded body can be made of plastic or metal. The kinetic energy of the drive beam is transferred to the rotating impeller and taken from the shaft attached to the underside. This results in a variety of properties and advantages. This turbine impeller is characterized by low manufacturing costs and a compact and small design. The turbine impeller is also very robust. After all, there is no cavitation and there is no risk of clogging with flotsam.
Die Weiterbildung hiervon gemäß Anspruch 8 geht von der Idee aus, das Turbinenlaufrad aus Einzelelementen zusammenzusetzen. Diese Einzelelemente betreffen jeweils einzelne Rinnenelemente.The development of this according to claim 8 is based on the idea of assembling the turbine impeller from individual elements. These individual elements relate to individual channel elements.
Eine bevorzugte Alternative hierzu besteht gemäß Anspruch 9 darin, dass der Formkörper aus einem Stück gebildet ist. Demgemäß kann das Turbinenlaufrad in einer Gussform gegossen werden. Eine Weiterbildung hiervon schlägt gemäß Anspruch 10 vor, daß die Rinnen als Kanäle in der Oberseite des Formkörpers ausgebildet sind. Der Formkörper ist dabei massiv vorzugsweise aus einem Stück ausgebildet. Die kanalförmigen Rinnen können dabei relativ tief im Formkörper ausgebildet sein. Die zentrale Spitze ist dann vorzugsweise versenkt. Diese Ausbildung der kanalförmigen Rinnen hat den Vorteil (insbesondere im Hinblick auf die versenkte Ausbildung der Spitze), daß das eingespritze Anstriebsmedium nahezu vollständig in die kanalförmigen Rinnen gelangt und nicht verloren geht.According to claim 9, a preferred alternative to this is that the molded body is formed from one piece. Accordingly, the turbine impeller can be cast in a mold. A development of this suggests that the channels are formed as channels in the top of the molded body. The molded body is preferably made of one piece. The channel-shaped grooves can be formed relatively deep in the molded body. The central tip is then preferably sunk. This design of the channel-shaped channels has the advantage (particularly with regard to the recessed configuration of the tip) that the injected drive medium almost completely gets into the channel-shaped channels and is not lost.
Die Weiterbildung gemäß Anspruch 11 schließlich hat den Vorteil, daß das Wasser nicht aus den Rinnen austreten kann.Finally, the development according to claim 11 has the advantage that the water cannot escape from the channels.
Zwei Ausführungsbeispiele eines erfindungsgemäßen Turbinenlaufrades werden nachfolgend anhand der Zeichnungen beschrieben. In diesen zeigt:Two exemplary embodiments of a turbine impeller according to the invention are described below with reference to the drawings. In these shows:
Fig. 1 eine perspektivische Ansicht einer ersten Ausführungsform desFig. 1 is a perspective view of a first embodiment of the
Turbinenlaufrades;Turbine wheel;
Fig. 2 eine Draufsicht auf das Turbinenlaufrad in Fig. 1;FIG. 2 shows a plan view of the turbine impeller in FIG. 1;
Fig. 3 eine Seitenansicht des Turbinenlaufrades in Fig. 1;3 shows a side view of the turbine impeller in FIG. 1;
Fig. 4 eine perspektivische Ansicht einer zweiten Ausführungsform des Turbinenlaufrades;4 shows a perspective view of a second embodiment of the turbine impeller;
Fig. 5 eine Draufsicht auf das Turbinenlaufrad in Fig. 4;FIG. 5 is a top view of the turbine impeller in FIG. 4;
Fig. 6 eine Seitenansicht des Turbinenlaufrades in Fig. 4.6 shows a side view of the turbine impeller in FIG. 4.
Das Turbinenlaufrad der ersten Ausführungsform in den Fig. 1 bis 3 besteht aus einem einstückigen Formkörper 1 insbesondere aus Metall oder Kunststoff. In diesem Formkörper 1 sind anströmungsseitig Schaufeln in Form von Rinnen 2 mit senkrechten Seitenwänden 3 ausgebildet. Der Verlauf dieser Rinnen 2 ist dabei die Kombination einer Spirale mit einer Wendel. Im Bereich der Drehachse laufen die Seitenwände 3 zu einer Spitze zusammen. In Strömungsrichtung verbreitern sich die Rinnen 2.The turbine impeller of the first embodiment in FIGS. 1 to 3 consists of a one-piece molded body 1, in particular made of metal or plastic. In this molded body 1, blades in the form of grooves 2 with vertical side walls 3 are formed on the inflow side. The course of these channels 2 is the combination of a spiral with a helix. The side walls 3 converge to a point in the region of the axis of rotation. The channels 2 widen in the direction of flow.
Auf der bezüglich der Spitze anderen Seite des Formkörpers 1 weist dieser eine Welle 4 auf.On the other side of the molded body 1 with respect to the tip, this has a shaft 4.
Die Funktionsweise ist wie folgt: Das Antriebsmedium wird über eine nicht dargestellte Düse in Anströmrichtung A1 eingespritzt. Das Antriebsmedium verteilt sich auf die insgesamt sechs Rinnen 2 (und beaufschlagt somit sämtliche Schaufeln) und strömt in Richtung Austrittsende der Rinnen 2. Die Ausströmrichtung A2 ist angedeutet. Unterseitig weist der Formkörper 1 die Welle 4 auf, welche die Bewegungsenergie des Strahls abnimmt.It works as follows: The drive medium is injected in the flow direction A1 through a nozzle, not shown. The drive medium is distributed over a total of six channels 2 (and thus acts on all blades) and flows in the direction of the outlet end of the channels 2. The outflow direction A2 is indicated. On the underside, the shaped body 1 has the shaft 4, which decreases the kinetic energy of the beam.
Das Turbinenlaufrad der zweiten Ausführungsform in den Fig. 4 bis 6 weist einen massiven Formkörper 1 aus Metall auf. In der Oberseite dieses Formkörpers 1 sind die vier Rinnen 2 relativ tief ausgebildet, wobei auch hier der Verlauf dieser Rinnen 2 die Kombination einer Spirale oder eines Teilkreises mit einer Wendel ist. Im Bereich der Drehachse laufen die Rinnen 2 zu einer Spitze zusammen, welche bezüglich des höchsten Punktes des Formkörpers 1 auf der Anströmseite versenkt ist. Im Gegensatz zu der ersten Ausführungsform verringert sich bei dieser zweiten Ausführungsform die Breite der Rinnen 2.The turbine impeller of the second embodiment in FIGS. 4 to 6 has a solid molded body 1 made of metal. In the top of this molded body 1, the four channels 2 are formed relatively deep, the course of these channels 2 also being the combination of a spiral or a partial circle with a spiral. In the area of the axis of rotation, the grooves 2 converge to a tip, which is sunk on the upstream side with respect to the highest point of the molded body 1. In contrast to the first embodiment, the width of the channels 2 is reduced in this second embodiment.
Auf der bezüglich der Spitze anderen Seite des Formkörpers 1 weist dieser auch bei dieser Ausführungsform eine Welle 4 auf.On the other side of the molded body 1 with respect to the tip, this body also has a shaft 4 in this embodiment.
Die Funktionsweise ist vom Grundprinzip her die gleiche wie bei der ersten Ausführungsform. Das zentral eingespritzte Antriebsmedium beaufschlagt sämtliche Schaufeln bzw. Rinnen 2 und strömt in Richtung Austrittsende der Rinnen. Im Gegensatz zu den Rinnen 2 der ersten Ausführungsform verkleinert sich bei dieser zweiten Ausführungsform deren Breite nach außen hin.The principle of operation is the same as in the first embodiment. The centrally injected drive medium acts on all blades or troughs 2 and flows in the direction of the outlet end of the troughs. In contrast to the channels 2 of the first embodiment, the width of this second embodiment decreases towards the outside.
Bei beiden Ausführungsformen kann noch eine - nicht dargestellte - Abdeckung der Rinnen 2 vorgesehen sein. In both embodiments, a cover (not shown) for the channels 2 can also be provided.
