Description
Einrichtung zum Antrieb einer Kondensatpumpe Aus dem Bestreben heraus, bei Dampfturbinenkraftanlagen den Betrieb der Hauptturbine von Störungen im elektrischen Netz oder in der Hausturbinenanlage unabhängig zu machen, ist man dazu übergegangen, die für den Betrieb erforderlichen Hilfsmaschinen jeweils von der Hauptturbine anzutreiben. So hat man beispielsweise vorgeschlagen, die Kondensatpumpe durch eine Wasserturbine anzutreiben, die mit Wasser aus einer mit der Hauptturbine gekuppelten Kühlwasserpumpe beaufschlagt wird. Vorteilhafter ist es noch, die Kondensatpumpe durch eine mit Öl von der vorhandenen Ölpumpe aus beaufschlagte Turbine anzutreiben. In der Regel liefert die Ölpumpe das für die Steuerung der Turbine benötigte Drucköl und gleichzeitig über ein. Druckminderventil das für die Schmierung der Lager erforderliche Lageröl.Device for driving a condensate pump Out of the endeavor, in steam turbine power plants the operation of the main turbine from disturbances in the electrical To make the grid or in the house turbine system independent, one has gone over to to drive the auxiliary machines required for operation from the main turbine. For example, it has been proposed to pump the condensate by a water turbine to drive the water from a cooling water pump coupled to the main turbine is applied. It is even more advantageous to have the condensate pump with a To drive oil from the existing oil pump acted upon turbine. Usually the oil pump delivers the pressure oil required to control the turbine and at the same time about a. Pressure reducing valve the bearing oil required to lubricate the bearings.
Erfindungsgemäß wird vorgeschlagen, von der für diese Zwecke vorhandenen Ölpumpe Öl zum Antrieb der mit der Kondensatpumpe gekuppelten Ölturbine zu verwenden, und das aus der Ölturbine austretende Öl, dessen Druck jetzt bei Abgabe einer Nutzarbeit vermindert worden ist, den Lagerstellen zuzuführen. Bei Anlagen mit einer Hilfsölpumpe für das Anfahren der Turbine wird man die besagte Ölturbine zunächst von der Hilfsölpumpe aus betreiben, bis die eigentliche Betriebsölpumpe schließlich an ihre Stelle tritt.According to the invention it is proposed to use the existing one for these purposes Oil pump to use oil to drive the oil turbine coupled to the condensate pump, and the oil emerging from the oil turbine, the pressure of which is now when a useful work is being performed has been reduced to supply the storage locations. For systems with an auxiliary oil pump To start up the turbine, the said oil turbine is first activated by the auxiliary oil pump operate off until the actual operating oil pump finally takes its place.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt. ' Die von der Hauptturbine i angetriebene Ölpumpe 2 liefert das Drucköl für die Hilfsturbine 3, die die Köndensatpumpe q. in Umlauf setzt. Das aus der Hilfsturbine 3 unter vermindertem Druck austretende Öl gelangt über die Leitung 5 z. B. zu den Lagerstellen 6 und 7. Die Ölzufuhr wird in Abhängigkeit von der Menge des in dem Kondensator 8 anfallenden Kondensats selbsttätig geregelt, z. B. indem ein Schwimmer auf das Regelventil 9 einwirkt. Im Strömungssinne des Öles ist vor dem Ventil 9 eine Umgehungsleitung i o vorgesehen, in der ein Druckminderventil i i angeordnet ist. Vor der Leitung i o ist eine Leitung 12 abgezweigt, die zu den Steuerorganen der Hauptturbine führt.An embodiment of the invention is shown in the figure. 'The oil pump 2 driven by the main turbine i supplies the pressure oil for the Auxiliary turbine 3, which the condensate pump q. puts into circulation. That from the auxiliary turbine 3 escaping under reduced pressure oil passes through line 5 z. B. to the Bearing points 6 and 7. The oil supply is dependent on the amount of in the Condenser 8 accumulating condensate automatically regulated, z. B. by a swimmer acts on the control valve 9. In the direction of flow of the oil is in front of the valve 9 a bypass line i o is provided, in which a pressure reducing valve i i is arranged is. In front of the line i o, a line 12 is branched off to the control organs the main turbine leads.
