Description
Vorrichtung zur Zuführung des Drucköls zum Laufradservomotor einer Kreiselmaschine, insbesondere Wasserturbine, mit senkrechter Welle und beweglichen Schaufeln Die Erfindung betrifft eine Vorrichtung zur Zuführung des Drucköls zum Laufradservomotor einer Kreiselmaschine, insbesondere einer Wasserturbine, mit senkrechter Welle und beweglichen Schaufeln und bezweckt, eine Überleitung des Drucköls aus dem feststehenden Turbinendrucklager in den sich drehenden Servomotor zu schaffen, so daß der in der Lagerfläche zwischen den Lagerelementen herrschende Lagerdruck die Abdichtung des Druckmittels an der Übergangsstelle bewirkt.Device for supplying the pressure oil to the impeller servo motor of a Centrifugal machine, especially a water turbine, with a vertical shaft and movable ones Shovels The invention relates to a device for supplying the pressure oil to Impeller servo motor of a centrifugal machine, in particular a water turbine, with a vertical Shaft and moving blades and aims to transfer the pressurized oil to create the fixed turbine thrust bearing in the rotating servo motor, so that the bearing pressure prevailing in the bearing surface between the bearing elements causes the pressure medium to be sealed at the transition point.
Bisher war es beispielsweise bei vertikalachsigen Maschinensätzen, die aus einer Wasserturbine und einem elektrischen Generator bestanden, üblich, die Druckölzuführung für den Laufradservomotor am .oberen Wellenende oberhalb der elektrischen Maschine anzuordnen. Hierbei mußte nicht nur die eigentliche Turbinenwelle, sondern auch die Generatorwelle der Länge nach durchbohrt werden, so daß die Ölzuführung ndbst Regelvorrichtung für die tief unten liegende Turbine oberhalb des Generators aufgestellt werden mußte. Hierdurch entstand nicht nur eine unpraktisch lange Druckrohrleitung, sondern es waren auch die Hersteller der Wasserturbine einerseits und der elektrischen Maschine anderseits bei ihrer konstruktiven Anordnung in hohem Maße voneinander abhängig.Up to now, for example, in the case of vertical-axis machine sets, which consisted of a water turbine and an electric generator, common, the pressure oil supply for the impeller servo motor at the .upper shaft end above the to arrange electrical machine. Not only had the actual turbine shaft, but also the generator shaft can be pierced lengthways, so that the oil supply ndbst control device for the turbine located deep below the generator had to be set up. This not only resulted in an impractically long pressure pipeline, but there were also the manufacturers of the water turbine on the one hand and the electric ones Machine on the other hand in their structural arrangement to a large extent from each other addicted.
Demgegenüber bringt die Erfindung eine wesentlich einfachere Lösung dieser Aufgabe. Bei dem auf der Abbildung dargestellten Ausführungsbeispiel wird die Druckölzuführung mit dem dort dargestellten Traglager in Verbindung gebracht, und zwar in der Weise, daß die Übertragung des Druckmittels vom feststehenden Lagerteil auf den relativ dazu bewegten Spurlagerteil in der Fläche des zwischen beiden Maschinenelementen gebildeten Lagers stattfindet.In contrast, the invention brings a much simpler solution this task. In the embodiment shown in the figure the pressurized oil supply brought into connection with the support bearing shown there, in such a way that the transfer of the pressure medium from the fixed bearing part on the track bearing part moved relative to it in the surface of the between the two machine elements formed camp takes place.
Die gezeichnete Spurlageranordnung ist unmittelbar auf den Turbinendeckel, also unterhalb des elektrischen Motors, aufgestellt gedacht. In der Lagerfläche a des Traglagers b berühren sich gegenseitig die stillstehende Lagerfläche a und der umlaufende Lagerringe. Im festen Lagerring d befinden sich Bohrungen, die mit von außen zugeführten Druckölrohren cl und c2 in Verbindung stehen. Von diesen Bohrungen mündet cl mit einem Stutzen h in eine Ringnut f, die sich auf der Unterseite des beweglichen Lagerringes e befindet; die andere, c2, mündet mit ihrem aufwärts führenden Stutzen i meine zweite Ringnutg, die sich ebenfalls auf der Unterseite des beweglichen Lagerringes e befindet. Die beiden Ringnuten f und g haben verschiedene Durchmesser. Von ihnen aus führen je eine Ölleitung k und l zum Laufradservomotor m zu den beiden gegenüberliegenden Seiten des Motorkolbens.The drawn thrust bearing arrangement is intended to be placed directly on the turbine cover, i.e. below the electric motor. In the bearing surface a of the support bearing b, the stationary bearing surface a and the rotating bearing rings touch each other. In the fixed bearing ring d there are bores which are in communication with externally supplied pressure oil pipes cl and c2. From these bores cl opens with a connecting piece h into an annular groove f, which is located on the underside of the movable bearing ring e; the other, c2, opens with its upwardly leading nozzle i my second ring groove, which is also located on the underside of the movable bearing ring e. The two ring grooves f and g have different diameters. From them one oil line k and l each lead to the impeller servo motor m on the two opposite sides of the motor piston.
Da auf diese Weise die beiden Arbeitsräume des Servomotors sowie die Leitungen c' und k einerseits und c2 und l anderseits mit dem Schieber in bekannter Weise in Verbindung stehen, ist der im übrigen bekannte Betrieb dieses Servomotors zur Verstellung der Laufradflügel ohne weiteres möglich. Zu dem Zweck führt durch die hohlgebohrte Wellen die Servomotorkolbenstange m' nach abwärts in das Innere des Laufrades und besorgt dprt die erforderliche Verdrehung der Laufradschaufeln.Since in this way the two working spaces of the servo motor and the lines c 'and k on the one hand and c2 and l on the other hand are connected to the slide in a known manner, the otherwise known operation of this servo motor for adjusting the impeller blades is easily possible. For this purpose, the servomotor piston rod m ' leads through the hollow bored shaft n downwards into the interior of the impeller and takes care of the required rotation of the impeller blades.
