Description
Dampfturbinenläufer-Drehvorrichtung mit durch Kondensat getriebener Drehturbine Die Erfindung betrifft eine Dampfturbinenläufer-Drehvorrichtung mit auf dem Läufer angeordneter Drehturbine, die durch Kondensat erhöhten Drucks angetrieben wird.Steam turbine rotor rotating device with condensate driven Rotary Turbine The invention relates to a steam turbine rotor rotary device with Rotary turbine arranged on the rotor, which is driven by condensate of increased pressure will.
Eine solche Turbine ist vorpatentiert. Bei ihr dient als Drehturbinenlaufrad ein Laufschaufelkranz der Dampfturbine selbst, also ein im Betriebe vom Dampf beaufschlagter Schaufelkranz. Das ist unerwünscht; denn die Schaufeln des Kranzes sind für den Dampfstrom profiliert, aber es wäre wünschenswert, sie dem Kondensatstrahl entsprechend zu profilieren.Such a turbine is pre-patented. It serves as a rotary turbine impeller a rotor blade ring of the steam turbine itself, i.e. one that is acted upon by steam during operation Blade ring. That is undesirable; for the shovels of the wreath are for him Steam flow is profiled, but it would be desirable to match it to the condensate jet to profile.
Die Erfindung sieht daher vor, daß das Drehturbinenlaufrad durch einen besonderen, hinter dem Laufschaufelkranz der Dampfturbinenendstufe und wesentlich außerhalb ihres Dampfstromes angeordnetem Schaufelkranz gebildet ist.The invention therefore provides that the rotary turbine impeller by a special, behind the rotor blade ring of the steam turbine output stage and essential is formed outside of their steam flow arranged blade ring.
Es kann dieser Drehturbinenlaufschaufelkranz in die Laufradscheibe der Dampfturbinenendstufe eingearbeitet oder auf einem eigenen, zusätzlichen Radkörper angeordnet oder auch in diesen eingearbeitet sein.This rotating turbine blade ring can be inserted into the impeller disk incorporated into the steam turbine output stage or on a separate, additional wheel center arranged or incorporated into these.
Die Zeichnung zeigt ein Beispiel, und zwar in F i g. 1 einen Teil- und Längsschnitt durch die Dampfturbine mit schematisch eingezeichneter Kondensatzuführung und in F i g. 2 eine Teildraufsicht auf die Stirnseite des Endstufenlaufschaufelkranzes der Dampfturbine und des Leit- und des Laufschaufelkranzes der Drehturbine.The drawing shows an example in FIG. 1 part and longitudinal section through the steam turbine with a schematically drawn condensate feed and in FIG. 2 is a partial plan view of the end face of the final stage blade ring the steam turbine and the guide and rotor blade ring of the rotary turbine.
Darin bezeichnet 1 die letzte Turbinenlaufscheibe, 2 die Endschaufel, 3 den Abdampfstutzen, 4 den Abströmkanal, 5 den Drehturbinenlaufschaufelkranz, 6 den zugehörigen Leitschaufelkranz, 7 die Kondensatleitung, 8 die Hauptkondensatpumpe. In Höhe des Umfanges des Schaufelkranzes 5 ist der Abdampfstutzen 3 mit seiner Wandung 9 zweckmäßig bis nahe an den Schaufelkranz 5 herangeführt. Mit 10 ist eine Hilfskondensatpumpe benannt.1 denotes the last turbine disk, 2 the end blade, 3 the exhaust steam nozzle, 4 the discharge duct, 5 the rotating turbine blade ring, 6 the associated guide vane ring, 7 the condensate line, 8 the main condensate pump. At the level of the circumference of the blade ring 5 is the exhaust steam connection 3 with its wall 9 expediently brought up to close to the blade ring 5. With 10 is an auxiliary condensate pump named.
