Description

In dem Hauptpatent ist ein Verfahren zum selbsttätigen Anlassen von Dampfturbinen in Vorschlag gebracht, bei welchem die einzelnen Abschnitte des Anlaßvorganges in Abhängigkeit von Meßgrößen selbsttätig gesteuert werden, welche die jederzeitige Beanspruchung der Turbine während des Anlaufens kennzeichnen. Als solche Meßgröße ist in dem Patent u. a. der Förderdruck der ölpumpe angegeben.In the main patent is a method for automatic starting of steam turbines Brought into proposal, in which the individual sections of the starting process as a function are automatically controlled by measured variables, which the constant stress mark the turbine during start-up. As such a measurable variable, the patent inter alia. the delivery pressure of the oil pump specified.

Gemäß der Erfindung wird diese Meßgröße dazu benutzt, einen bestimmten Teil des gesamten Anlaßverfahrens zu übernehmen, nämlich den zum Absaugen des Stopfbüchsendampfes vorgesehenen Strahlsauger einzuschalten. Die Einschaltung des Strahlsaugers erfolgt mittels eines in der Dampf- oder Wasserzuleitung des Saugers vorgesehenen Ventils, welches in Abhängigkeit vom Druck der Ölversorgung geöffnet wird. Durch diese Einrichtung ist dafür gesorgt, daß der Strahlsauger zur Absaugung des in den Stopfbüchsen anfallenden Dampfes unabhängig von der Aufmerksamkeit des Überwachungspersonals rechtzeitig eingeschaltet wird.According to the invention, this measured variable is used to determine a certain part of the total To take over the starting process, namely to switch on the jet suction device provided for sucking off the stuffing box steam. The jet suction device is switched on by means of a device provided in the steam or water supply line of the suction device Valve, which is opened depending on the pressure of the oil supply. Through this Facility is ensured that the jet suction device for sucking off the stuffing boxes generated steam regardless of the attention of the monitoring staff is switched on in time.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung im Schema dargestellt.An embodiment of the invention is shown in the drawing in the scheme.

ι ist die Turbine, welche den Stromerzeuger 2 antreibt. 3 und 4 sind die Stopfbüchsen, die durch Rohrleitungen S und 6 an den Strahlsauger 7 angeschlossen sind. Der Strahlsauger wird mit Frischdampf betrieben, welcher durch die Leitung 8 zugeführt wird. In dieser Leitung ist ein Ventil 9 vorgesehen, welches mittels eines kleinen Kraftgetriebes 10 verstellt wird. Das Ventil wird durch eine Feder dieses Getriebes geschlossen gehalten. Unterhalb des Kraftkolbens ist eine Leitung 11 eingeführt, welche mit der Druckleitung der Ölversorgung in Verbindung steht.ι is the turbine that drives the generator 2. 3 and 4 are the stuffing boxes, which are connected to the ejector 7 by pipes S and 6. The ejector is operated with live steam, which is supplied through line 8. A valve 9 is provided in this line, which is adjusted by means of a small power transmission 10. The valve is through a spring of this transmission kept closed. Below the power piston is a Line 11 introduced, which with the pressure line the oil supply is connected.

Nimmt der Öldruck beim Anlassen der Turbine einen bestimmten Wert an, so wird die Federkraft überwunden und der Kraftkolben nach oben bewegt, wodurch das Ventil geöffnet wird. Die Zufuhr des Frischdampfes zum Strahlsauger 7 wird damit freigegeben, so daß der in den Stopfbüchsen 3 und 4 anfallende Dampf abgesaugt wird. Bei Sinken des Öldruckes durch Abstellen der Turbine wird das Absperrventil 9 wieder geschlossen und somit der Strahlsauger selbsttätig wieder abgeschaltet.If the oil pressure assumes a certain value when the turbine is started, then the spring force is overcome and the power piston moves upwards, causing the valve is opened. The supply of the live steam to the ejector 7 is thus released, so that the steam accumulating in the stuffing boxes 3 and 4 is sucked off. When sinking the oil pressure by turning off the turbine, the shut-off valve 9 is closed again and thus the ejector automatically switched off again.
