PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Steuerungsvorrichtung für Schiffsturbinenanlagen, bei denen die Einlaßorgane für Vorwärts- und Rückwärtsturbinen von einer gemeinsamen Steuerwelle aus verstellt werden.The invention relates to a control device for ship turbine systems in which the inlet organs for forward and reverse turbines from a common control shaft can be adjusted.
Sie besteht darin, daß die Umschaltung der zu einer Zwischenstufe einer Turbine führenden Ausflußleitung der Hilfsmaschine in Abhängigkeit von der Stellung der übrigen Ventile ίο ebenfalls von der gemeinsamen Steuer welle aus vorgenommen wird.It consists in the switching of the leading to an intermediate stage of a turbine Outflow line of the auxiliary machine depending on the position of the other valves ίο also from the common tax shaft is made out.
Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht,
und zwar ist
Fig. ι eine Oberansicht, undThe subject matter of the invention is illustrated in the drawing in an exemplary embodiment, namely is
Fig. Ι a top view, and
Fig. 2 eine Vorderansicht einer Schiffsturbinenanlage. Fig. 2 is a front view of a marine turbine system.
α und b sind zwei mit Rückwärtsturbinen versehene gleichachsige Turbinen, welche durch Zahnradvorgelege c auf eine gemeinsame Welle d wirken, e ist eine für beide Turbinen ä, b gemeinsame Daumenwelle, deren Kurvenscheiben die Einstellung der Dampfeinlaßorgane f bewirken. Die Verstellung der Daumen-V25 welle e erfolgt in irgendeiner Weise vom Handrad g aus. α and b are two coaxial turbines provided with backward turbines, which act on a common shaft d through gear reduction c, e is a thumb shaft common to both turbines ä, b , the cam plates of which effect the adjustment of the steam inlet elements f. The adjustment of the thumb V 25 shaft e takes place in some way from the handwheel g .
Zum Antrieb der Schleuderluft-, Kondensat- und Umlaufpumpen werden Hilfsdampfmaschinen verwendet, deren Abdampf einer Zwischenstufe der einen oder anderen Turbine in an sich bekannter Weise zugeleitet wird. Unterschreitet nun die Belastung dieser Turbine eine bestimmte Grenze, so würde dieselbe durch den ihrer Zwischenstufe ständig zuströmenden Abdampf zum Durchgehen gebracht. Um dies zu verhüten, muß dann eine Umschaltung der Ausflußleitung der Hilfsmaschine nach dem Kondensator oder nach der Atmosphäre vorgenommen werden. Gemäß der Erfindung wird diese Umschaltung von der gemeinsamen Steuerwelle β aus vorgenommen. Und zwar ist die Einrichtung dann so getroffen, daß der für das Umschaltventil auf der Daumenwelle vorgesehene Nocken erst dann zum Eingriff kommt, wenn die Einlaßorgane der betreffenden Vorwärtsturbine bereits geschlossen sind.To drive the centrifugal air, condensate and circulation pumps, auxiliary steam engines are used, the exhaust steam of which is fed to an intermediate stage of one or the other turbine in a manner known per se. If the load on this turbine falls below a certain limit, it would be made to pass by the exhaust steam constantly flowing in to its intermediate stage. To prevent this, the outflow line of the auxiliary machine must then be switched to the condenser or to the atmosphere. According to the invention, this switchover is carried out from the common control shaft β . The device is designed in such a way that the cam provided for the changeover valve on the thumb shaft only comes into engagement when the inlet organs of the relevant forward turbine are already closed.
