Description

Einrichtung zur Regelung des Kühlwasserzuflusses bei Dampfverbrauchern, insbesondere Dampfturbinen, welche mit Einspritzkühler arbeiten. Bei Heißdampfkiihlern, die vor Kraftmaschinen in die Rohrleitung eingeschaltet sind und welche mit Wassereinspritzung arbeiten, besteht die Gefahr, daß, wenn mit dem Stillsetzen der Turbine oder Kolbendampfmaschine nicht gleichzeitig auch der Zufluß des Einspritzwassers in den Kühler unterbunden wird, das überschußwasser in die Rohrleitung und später in den Dampfverbraucher gelangt und Schaden anrichtet.Device for regulating the cooling water flow for steam consumers, especially steam turbines that work with injection coolers. For hot steam coolers, which are switched on before engines in the pipeline and which with water injection work, there is a risk that if the turbine or piston steam engine is shut down the flow of injection water into the radiator is not also prevented at the same time the excess water into the pipeline and later into the steam consumer arrives and causes damage.

Die Erfindung will diesen Übelstand vermeiden und besteht darin, daß die Regelung des Zuflusses des Einspritzwassers mittelbar oder unmittelbar zwangläufig in Abhängigkeit von dem Dampffloß hinter dem Dampfabsperrventil der Kraftmaschine gebracht ist, z. B. indem ein vom Dampfdruck der Kraftmaschine beeinflußtes Organ, wie Zylinderkolben oder Membranregler, den Zulauf des Einspritzwassers zum Kühler oder die Dampfzuleitung zur Einspritzwasserpumpe regelt, oder indem die Einspritzwasserpumpe für den Kühler des überhitzten Dampfes an die Dampfzuleitung der Turbine oder Kolbendampfmaschine angeschlossen ist, so daß mit der Unterbrechung der Dampfzufuhr in die Turbine auch zwangl,äufig gleichzeitig der Dampf für die Einspritzwasserpumpe abgeschaltet wird, also beide gleichzeitig stehenbleiben. Die Dampfabnahme für die Einspritzwasserpumpe muß selbstverständlich an einer Stelle der Dampfzuführungsleitung zur Turbine erfolgen, deren Druck bei Außerbetriebsetzung der Maschine sich derart vermindert, daß der gewünschte Zweck erreicht wird.The invention wants to avoid this drawback and consists in that the regulation of the inflow of the injection water directly or indirectly inevitably depending on the steam flow behind the steam shut-off valve of the engine is brought, z. B. by an organ influenced by the steam pressure of the engine, such as cylinder pistons or diaphragm regulators, the feed of the injection water to the cooler or regulates the steam supply line to the injection water pump, or by the injection water pump for the cooler of the superheated steam to the steam supply line of the turbine or piston steam engine is connected, so that with the interruption of the steam supply to the turbine too Inevitably, frequently the steam for the injection water pump is switched off at the same time, so both stop at the same time. The steam take-off for the injection water pump must of course take place at one point of the steam supply line to the turbine, whose pressure when the machine is shut down is so reduced that the desired purpose is achieved.

In der Zeichnung ist eine derart ausgeführte Anlage als Beispiel schematisch dargestellt.A system designed in this way is shown schematically as an example in the drawing shown.

Der durch die Rohrleitung i vom (nicht gezeichneten) Überhitzer kommende Dampf gelangt durch den Heißdampfkühler a über Leitung 3, den Wasserabscheider 4., das Hauptabsperrventil5 und das selbsttätige SChnellschlußventil 6 zur Turbine 7 und von dort über Leitung 8 zum Kondensator 9. Die Kühlung des überhitzten Dampfes erfolgt im Kühlerz durch Einspritzen von Druckwasser durch Leitung io. Diese steht mit der Wasserseite einer Kolbenpumpe i z in Verbindung, deren Dampfseite über Leitung i z einseitig i -in die Turbine 7 angeschlossen ist, während der Abdampf über Leitung 13 zum Kondensator führt, so daß mit dem Fallen des Druckes in der Turbine auch selbsttätig der Dampfdruck für die Einspritzwasserpumpe i i in gleicher Weise fällt, also ein weiteres Einspritzen von Kühlwasser in den Kühler -- unterbunden wird. Der Dampf zur Inbetriebsetzung der Einspritzwasserpumpe kann je nach Erfordernis sowohl hinter dem Schnellschlußventil, vor den Düsen oder auch an einer beliebigen Stelle der verschiedenen Stufen der Turbine abgenommen werden.The steam coming through the pipe i from the superheater (not shown) passes through the superheater a via line 3, the water separator 4., the main shut-off valve 5 and the automatic quick-closing valve 6 to the turbine 7 and from there via line 8 to the condenser 9. The cooling of the Superheated steam takes place in the cooler ore by injecting pressurized water through line io. This is connected to the water side of a piston pump iz, the steam side of which is connected on one side i -in the turbine 7 via line iz, while the exhaust steam leads to the condenser via line 13 , so that when the pressure in the turbine drops, the steam pressure automatically increases for the injection water pump ii falls in the same way, that is, a further injection of cooling water into the radiator - is prevented. The steam for starting the injection water pump can be taken, depending on requirements, both behind the quick-acting valve, in front of the nozzles or at any point in the various stages of the turbine.
