Description

Ringförmige Leitvorrichtung für Wasserturbinen. Es ist bei Wasserturbinen bekannt, den Wasserdurchfluß durch Verstellung der einen Wand der Leitvorrichtung gegenüber der feststehenden anderen Wand zu regeln. Die Verengung des ringförmigen Querschnittes der Leitvorrichtung erfolgte bisher an dem dem Laufrad zugekehrten Ende der Leitvorrichtung, so daß hinter dem Austrittsende der Leitvorrichtung eine plötzliche Querschnittsvergrößerung und beim Übertritt des Wassers aus dem Leitrad in das Laufrad starke Wirbelbildungen auftraten. Diese Nachteile werden gemäß der Erfindung dadurch behoben, daß der ringförmige Querschnitt der Leitvorrichtung am Austrittsende konstant erhalten wird." Hierzu ist die verstellbare, mit ihrem zylindrischen Teil in dem Turbinengehäuse geführte Wand der Leitvorrichtung derart ausgestaltet, daß bei stets gleichbleibendem Austrittsquerschnitt der düsenartig geformte Eintrittsquerschnitt beliebig eingestellt werden kann.Annular guide device for water turbines. It's with water turbines known, the water flow by adjusting one wall of the guide device to regulate against the fixed other wall. The narrowing of the annular Cross-section of the guide device was previously carried out on the one facing the impeller End of the guide device, so that behind the exit end of the guide device a sudden increase in cross-section and when the water passes out of the diffuser strong eddies occurred in the impeller. These disadvantages are according to the Invention solved in that the annular cross-section of the guide device on The outlet end is kept constant. "For this purpose, the adjustable, with its cylindrical Part of the wall of the guide device that is guided in the turbine housing is configured in such a way that that with the outlet cross-section always remaining the same, the nozzle-like shaped inlet cross-section can be set at will.

Auf der Zeichnung ist eine Wasserturbine gemäß der Erfindung in einem Ausführungsbeispiel dargestellt. Die Leitvorrichtung der Turbine wird von der feststehenden Wand r und von de; beispielsweise mittels der Zugstange 3 verstellbaren Wand 2 gebildet. Bei einer zwecks Regelung des Wasserdurchflusses erfolgten Verstellung der Wand 2 wird der düsenartig geformte Eintrittsquerschnitt geändert, während der dem Laufrad q. zugekehrte Austrittsquerschnitt der Leitvorrichtung konstant erhalten wird.In the drawing, a water turbine according to the invention is in one Embodiment shown. The guiding device of the turbine is from the fixed Wall r and from de; formed for example by means of the pull rod 3 adjustable wall 2. When the wall is adjusted to regulate the water flow 2 the nozzle-like shaped inlet cross-section is changed, during that of the impeller q. facing exit cross-section of the guide device is kept constant.
