Description

Leitapparat mit drehbaren Schaufeln für Turbinen u. dgl. Bisher bekannte Leitapparate mit drehbaren Leitschaufeln für Turbinen, insbesondere Francisturbinen, gestatten durch gleichartige Verstellung aller Leitschaufeln Richtung und Größe der Austrittsgeschwindigkeit des Wassers aus dem Leitrad zwecks Regelung der Leistung zu verändern, nicht aber, den Sinn der Umfangskomponente dieser Geschwindigkeit umzukehren und so die Drehrichtung der aus dem Leitrad kommenden Zirkulationsströmung zu ändern, weil die Schaufeln bisher üblicher Ausführung sich gegenseitig überdecken.Diffuser with rotatable blades for turbines and the like Nozzles with rotating guide vanes for turbines, in particular Francis turbines, allow direction and size to be adjusted by adjusting all guide vanes in the same way the exit speed of the water from the diffuser for the purpose of regulating the output to change, but not to change the meaning of the circumferential component of this speed to reverse and so the direction of rotation of the circulation flow coming from the stator to change because the blades of the usual design overlap each other.

Den Gegenstand der Erfindung bildet ein Leitapparat für Turbinen u. dgl. mit drehbaren Schaufeln, bei dem diese derart ausgebildet sind, daß sie von der geschlossenen Stellung aus nach beiden Seiten öffnen, also beide Dreheinrichtungen des Leitradstromes erzeugen können. Hierdurch ist die Möglichkeit geschaffen, beim Abstellen des N;Laschinensatzes durch Umstellen der Leitschaufeln eine Bremswirkung hervorzubringen oder bei entsprechender Laufradkonstruktion dieses in seiner Drehrichtung umkehrbar, reversibel zu machen.The object of the invention forms a diffuser for turbines u. Like. With rotatable blades, in which these are designed such that they of open to both sides from the closed position, i.e. both rotating devices can generate the stator flow. This creates the possibility when Shutting down the N; machine set by moving the guide vanes has a braking effect to produce or with a corresponding impeller construction this in its direction of rotation reversible, to make reversible.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes, angewendet bei einer Francisturbine, und zwar sind die Schaufeln zu einzelnen Gruppen zusammengefaßt in verschiedenen Stellungen gezeichnet.The drawing illustrates an embodiment of the subject matter of the invention, used in a Francis turbine, namely the blades are in individual groups drawn together in different positions.

Die Leitschaufeln i werden in bekannter Weise um Achsen gleichzeitig und gleichartig bewegt, die entweder durch fest mit den Leitradringen 2 verbundene Bolzen oder durch Zapfen gebildet werden, die mit den Schaufeln fest sind. Bei der Ausbildung der Leitschaufeln nach der vorliegenden Erfindung überdecken sich jedoch die Schaufeln in geschlossener Stellung im Gegensatz zu bisher bekannten Ausführung nicht, sondern lassen zwischen den Kanten einen übrigens beliebig klein wählbaren Zwischenraum, demzufolge sie sich in keiner Stellung gegenseitig feststellen. Die Leitschaufeln können daher von der Schlußstellung aus mit der einen oder mit der anderen Hochkante nach einwärts gedreht werden, wodurch auch das Wasser in der einen oder in der anderen Drehrichtung auf das Laufrad geleitet werden kann. In der Zeichnung sind die Schaufeln links oben vollständig geöffnet für eine Drehrichtung des Rades im Uhrzeigersinn, während die unten gezeichneten halb geöffnet sind, jedoch für entgegengesetzten Drehsinn zur Erzielung einer Rückwärtsdrehung des Laufrades oder einer Bremswirkung der Turbine. Rechts in der Zeichnung ist die Schlußstellung dargestellt.The guide vanes i are in a known manner about axes simultaneously and moved in the same way, either by being firmly connected to the stator rings 2 Bolts or tenons that are fixed to the blades. In the However, the design of the guide vanes according to the present invention overlap the blades in the closed position in contrast to the previously known design not, but leave an arbitrarily small selectable between the edges In between, they do not find each other in any position. the Guide vanes can therefore from the final position with the one or with the the other upright can be turned inwards, which also causes the water in one or can be directed to the impeller in the other direction of rotation. In the drawing the blades at the top left are fully open for one direction of rotation of the wheel clockwise while the ones drawn below are half open, but for opposite direction of rotation to achieve a reverse rotation of the impeller or a braking effect of the turbine. The final position is shown on the right in the drawing.

Claims (1)

PATENT-ANspRUcii: Leitapparat mit drehbaren Schaufeln für Turbinen u. dgl., dadurch gekennzeichnet, daß die Leitschaufeln sich nicht überdecken und von der Schlußstellung aus vorwärts und rückwärts geöffnet, also für leide Drehrichtungen eingestellt werden können.PATENT APPLICATION: Nozzle with rotating blades for turbines and the like., characterized in that the guide vanes do not overlap and from the final position open forwards and backwards, so for poor directions of rotation can be adjusted.
