Description

Entlastungsvorrichtung der Regelungsschienen von Turbinen mit länglicher Beaufschlagungsöffnung. Bei den Peltonrädern mit Beaufschlag#-ung durch einen runden Wasserstrahl beruht ;die im allgemeinen verwendete und gut bewährte Regelung idarauf, @daß durch ;den die Regelung herbeiführenden Servomotor ein birnenförmiger Rotationskörper, die sogenannte Nadel, in der Richtung (der Beaufschlagungsöffnung ein- und ausgeschoben, somit die Öffnung verengt oder erweitert wird. Für eine Turbine - mit länglicher Beau fschlagungsöffnung, wie sie insbesondere bei (der Bänki-Tur'bine vorhanden ist, kann unter Beibehaltung dieser Anordnung ider Nadelregelung eine ähnliche Regelung geschaffen werden, wenn nur anstatt einer Regelungsnadel ein prismatischer Körper (eine Schiene) gewählt wird, ideren Oberschnitt ungefähr (die Form besitzt wie ider Meridiansohnitt des obenerwähnten Rotationskörpers. Im Falle einer länglichen Beaufschlagungsöffnung und großer Druckhöhe wirken aber große Kräfte auf die Regelungsschiene, so @daß ein. Servomotor von großen Abmessungen erforderlich sein würde.Relief device of the regulating rails of turbines with elongated Loading opening. With the Pelton wheels with loading by a round one Water jet is based; the generally used and well-proven control is based on @ that through; the servomotor that brings about the regulation is a pear-shaped rotating body, the so-called needle, pushed in and out in the direction (of the application opening, thus the opening is narrowed or widened. For a turbine - with an elongated one Beau fschlagungsaufnahme, as it is particularly present in (the Bänki-Tur'bine is, a similar control can be performed while maintaining this arrangement in the needle control can be created if only a prismatic body instead of a regulating needle (a rail) is chosen, roughly the same as the top section (the shape has the same as the Meridian habit of the above-mentioned body of revolution. In the case of an elongated loading opening and high pressure head, however, great forces act on the control rail, so @ that a. Large size servo motor would be required.

Den Gegenstand der vorliegenden Erfindung bildet nun die hydraulische Ausgleichung der auf die Regelungsschiene einwirkentden Drucke und somit eine teilweise Entlastung der zur Bewegung der Schiene dienenden Gestänge und des Servomotors, was gemäß dem in Abb. r und 2 in Schnitt und Aufsicht dargestellten Ausführungsbeispiel durch Kolben erreicht wird. Hier besitzt die Schiene 31 zwei Betätigungsstangen 32. Die Anwendung von mehr als zwei Stangen wird nur ausnahmsweise bei ,sehr langen Beaufschlagungsöffnungen zweckmäßig sein. Die Schienenstangen sinid an Kolben 33 befestigt, «-elche in den aus dem Wasserkasten herausragenden Zylindern. 37 laufen. Die Treibstangen der Kolben sind vorteilhaft an die Kurbelarme 34. der gemeinsamen Achse 38 angeschlossen, welche .durch den Servomotor angetrieben wird'. In dieser Weise ist die parallele Bewegung der Treibstangen gesichert. Zur Führung ist die Schiene an beiden Enden, mit Zapfen 35 versehen, auf welche Schlitten 39 aufgeschoben sind; die Schlitten 39 laufen in Nuten der Seitenwände des Wasserkastens. Die Nuten sind, durch die an den Enden der Schiene angebrachten Lappen 4o abgedeckt, wodurch von den Nuten Ablagerungen ferngehalten werden. Die Erfindung beschränkt sich natürlich nicht auf die beispielsweise (dargestellte bauliche Lösung, vielmehr sind innerhalb des Rahmens derselben mannigfache Änderungen möglich. Wesentlich ist aber die Bedingung, daß die parallele Bewegung der Kolben, und idamit der Tragstangen der Schiene gesichert sei.The subject of the present invention now forms the hydraulic equalization of the pressures acting on the control rail and thus a partial relief of the linkage and the servo motor used to move the rail, which is achieved by pistons according to the embodiment shown in Fig. R and 2 in section and top view will. Here the rail 31 has two actuating rods 32. The use of more than two rods will only be expedient in exceptional cases in the case of very long loading openings. The rail rods are attached to pistons 33, in the cylinders protruding from the water tank. 37 run. The drive rods of the pistons are advantageously connected to the crank arms 34 of the common axis 38, which is "driven by the servomotor". In this way, the parallel movement of the connecting rods is ensured. For guidance, the rail is provided at both ends with pins 35, onto which carriages 39 are pushed; the carriages 39 run in grooves in the side walls of the water tank. The grooves are covered by the tabs 4o attached to the ends of the rail, so that deposits are kept away from the grooves. The invention is of course not limited to the structural solution shown, for example, but various changes are possible within the framework of the same. However, the essential condition is that the parallel movement of the pistons, and thus the support rods of the rail, is ensured.
