Description
Regler für Wasserturbinen mit drehbaren Leitrad- und drehbaren Laufradschaufeln. Wasserturbinen mit drehbaren Leit- und Laufradschaufeln erfordern zur Einstellung von Teilbeaufschlagungen nicht allein eine Verstellung der Leitradschaufeln, sondern auch eine gleichzeitige Verstellung der Laufradschaufeln, wenn höchste Wirkungsgrade für jede Beaufschlagung erreicht werden sollen. Die Verstellung der Leitradschaufeln erfolgt gewöhnlich durch einen Regulierring, welcher unter Einschaltung von Zugstangen und Hebeln von einer Regulierwelle aus bewegt wird, die Bewegung der in der Nabe um eine Achse drehbar gelagerten Laufradschaufeln in ähnlicher Weise.Regulator for water turbines with rotating stator and rotating impeller blades. Water turbines with rotating guide and impeller blades require adjustment partial admission not only an adjustment of the stator blades, but also a simultaneous adjustment of the impeller blades, if the highest efficiency should be achieved for each admission. Adjustment of the stator blades usually takes place by means of a regulating ring, which is activated by means of tie rods and levers are moved by a regulating shaft, the movement of the in the hub impeller blades rotatably mounted about an axis in a similar manner.
Für jede Beaufschlagung der Turbine gibt es, um höchste Wirkungsgrade zu erreichen, nur »einet< bestimmte Stellung der Leitrad-und Laufradschaufeln zueinander. Eine gegenseitige Abhängigkeit dieser beiden Stellungen könnte durch die Einschaltung von Hebelwerken und Zugstangen erreicht werden, würde aber umfangreiche und somit teure Konstruktionen ergeben, ohne die erforderliche Genauigkeit für die gegenseitige Schaufelstellung zu erreichen. Die nachstehend beschriebene Erfindung bezweckt das genaue Abhängigkeitsverhältnis durch die Einschaltung einer Kurvenbahn, deren Form durch das Abhängigkeitsverhältnis der Leitradschaufelstellung zur Laufradschaufelstellung bestimmt ist, zwischen den beiden Regulierwellen herzustellen.Every time the turbine is acted upon, there is a high degree of efficiency to achieve only "one" specific position of the stator and impeller blades to each other. A mutual dependence of these two positions could result the inclusion of lever mechanisms and tie rods would be achieved, but extensive and thus result in expensive constructions without the required accuracy for the to achieve mutual blade position. The invention described below aims to achieve the exact dependency ratio by switching on a cam track, their shape through the relationship between the stator vane position and the impeller vane position is intended to be established between the two regulating shafts.
Abb, i und 2 zeigen beispielsweise zwei verschiedene Ausführungsformen dieser Erfindung.Figs. I and 2 show, for example, two different embodiments of this invention.
In Abb. x wird in üblicher Weise die Regulierwelle R1 durch einen Servomotor S1 verstellt; gegen eine auf dieser Regulierwelle R1 aufgesetzte Kurve-ibahn K, stützt sich der Regulierhebel H2 der Regulierwehe R2, wodurch das Verhältnis der Verdrehungswinkel der beiden Regulierwellen R1 und R2 zueinander für jede Lage beliebig eingestellt werden kann. _ In Abb, 2 wird jede der beiden Regulierwellen R1 und R2 durch einen besonderen Servomotor S1 und S2 verstellt. Die Zwangläufigkeit für deren Bewegungen wird dadurch erreicht, daß das Steuerventil St., des Servomotors S2 für die Regulierwelle R2 durch eine mit dem Servomotor S1 verbundene Kurvenbahn El betätigt wird. Auch in diesem Falle entspricht jeder Stellung der Regulierwelle R1 Eine durch Formgebung der Kurvenbahn K, bestimmte Stellung der Regulierwelle R2.In Fig. X, the regulating shaft R1 is in the usual way by a Servomotor S1 adjusted; against a cam track placed on this regulating shaft R1 K, the regulating lever H2 rests on the regulating bow R2, thereby reducing the ratio the angle of rotation of the two regulating shafts R1 and R2 to one another for each position can be set at will. _ In Fig. 2, each of the two regulating waves R1 and R2 adjusted by a special servo motor S1 and S2. The inevitability for their movements is achieved in that the control valve St., the servo motor S2 for the regulating shaft R2 through a cam track connected to the servomotor S1 El is operated. In this case, too, each position corresponds to the regulating shaft R1 A position of the regulating shaft determined by the shaping of the cam track K R2.
