Description
Die Erfindung betrifft ein mehrfach beauf- j schlagtes Achsialrad für Dampf- oder Gastur- j binen, bei welchem die Beaufschlagung von der j Zuführungsstelle des Treibmittels aus nach beiden Seiten des Radumfanges erfolgt. Sie besteht darin, daß zwecks Beseitigung der Ouerbelastung der Welle mindestens zwei einander diametral gegenüberliegende Treibmittelzuführungsstellen vorgesehen sind.The invention relates to an axial impeller with multiple pressures for steam or gas turbines binen, in which the application from the j point of supply of the propellant after takes place on both sides of the wheel circumference. It consists in that in order to eliminate the Overloading of the shaft at least two diametrically opposed propellant supply points are provided.
ίο Der Erfindungsgegenstand ist in der Zeichnung in einer Ausführung beispielsweise veranschaulicht. Hierin zeigt Abb. ι einen Schnitt nach Linie A-A der Abb. 2, Abb. 2 die Abwicklung eines Laufrades mit den verschiedenen Beaufschlagungsstellen, während Abb. 3 einen Schnitt nach der Linie B-B der Abb. 2 und Abb. 4 ein mehrkränziges, ebenfalls mehrfach beaufschlagtes Laufrad im Querschnitt darstellen.ίο The subject matter of the invention is illustrated in the drawing in one embodiment, for example. Here, Fig. 1 shows a section along line AA of Fig. 2, Fig. 2 shows the development of an impeller with the various impact points, while Fig. 3 shows a section along line BB of Fig. 2 and Fig. 4 a multi-crowned, also multiple show the loaded impeller in cross section.
Es bezeichnet α ein vom Treibmittel mehrfach beaufschlagtes Laufrad für Dampf- oder Gasturbinen. Die Zuführung des Treibmittels erfolgt in b. Nach Austritt aus dem Laufrad wird der Dampfstrahl nach einmaliger Beaufschlagung des Rades geteilt und zu beiden Seiten des Radumfanges nacheinander 'Leitvorrichtungen c zugeführt, um immer von neuem in dem Laufrad zur Arbeitsleistung unter weiterer Expansion herangezogen zu werden.It denotes α an impeller for steam or gas turbines that is acted upon several times by the propellant. The propellant is supplied in b. After exiting the impeller, the steam jet is split after a single application of the wheel and supplied to both sides of the wheel circumference one after the other 'guide devices c , in order to be used again and again in the impeller for work performance with further expansion.
Um eine bei einziger Dampfzuführung auftretende Ouerbelastung der Welle zu vermeiden, ist es vorteilhaft, mindestens zwei diametral gegenüberliegende Einlaßstellen für das Treibmittel vorzusehen.In order to avoid excessive load on the shaft with a single steam supply, it is advantageous to have at least two diametrically opposite inlet points for to provide the propellant.
Sind hohe Druckgefälle zu verarbeiten, so kann es zweckmäßig sein, wie in Abb. 4 veranschaulicht, das Laufrad mehrkränzig auszubilden. Hierdurch ergibt sich der Vorteil, daß die Auslaßgeschwindigkeit zwischen den Kränzen erhalten bleibt, während bei einem einkränzigen Rade bei jedem Durchgang die Auslaßgeschwindigkeit als verloren gelten muß. Die wiederholte Zuführung des Dampfes zu beiden Seiten der Zuführungsstelle oder Zuführungsstellen erfolgt hierbei in genau derselben Weise wie bei einkränzigen Rädern.If high pressure gradients have to be processed, it can be useful, as illustrated in Fig. 4, to train the impeller with multiple rings. This has the advantage that the outlet speed between the Wreaths are retained, while with a single-wreathed wheel, the Outlet velocity must be considered lost. The repeated supply of steam on both sides of the feed point or feed points takes place in exactly the same Way as with single-ring wheels.
Reicht ein Rad für die Energieumsetzung des Dampfes nicht aus, so können dem einen im Erfindungssinne ausgebildeten, mehrfach beaufschlagten Hochdrucklaufrad ein oder mehrere weitere Laufräder gleicher oder anderer Bauart als Niederdruckteil nachgeschaltet werden.If one wheel is not sufficient for the energy conversion of the steam, one can trained in the sense of the invention, multiple acted upon high pressure impeller one or several other impellers of the same or a different design are connected downstream as a low-pressure part will.
