PATENTAMT.PATENT OFFICE.
Bei Turbinen, die mit Dämpfen oder Gasen von hoher Temperatur arbeiten sollen, werden die Schaufeln der Lauf- und Leiträder zweckmäßig aus Stoffen, welche möglichst hohe Temperatur vertragen können (wie Quarz u. dgl.), hergestellt. Für die anderen Teile der Turbine, wie die Kränze oder die Lagerungsteile der Lauf- und Leiträder sowie das Gehäuse können dagegen praktischFor turbines that are supposed to work with vapors or gases at high temperatures The blades of the impellers and idlers are expediently made of materials that can withstand the highest possible temperature (such as Quartz and the like). For the other parts of the turbine, like the wreaths or the Bearing parts of the impellers and idlers as well as the housing, however, can be practical
Jo nur die üblichen, weniger temperaturbeständigen Metalle als Baustoff in Betracht kommen. Es besteht dann die Gefahr, daß diese Metalle unter der Einwirkung des heißen Treibmittels ihre Festigkeit einbüßen oder sogar schmelzen können.Jo only the usual, less temperature-resistant Metals come into consideration as building materials. There is then the risk that these metals under the action of hot blowing agent can lose their strength or even melt.
Um dies zu verhindern, kann man den aus feuerbeständigem Stoff herzustellenden Schaufeln der Laufräder der Turbine eine fiächenförmige Erweiterung oder einen Schild geben,To prevent this from happening, one can use the shovels made of fire-resistant material give the impellers of the turbine a flat extension or a shield,
ao welcher ebenfalls aus möglichst feuerbeständigem Stoff hergestellt ist. Ähnliche Schilder aus gleichem Stoff wie die Schaufeln sind zwar schon jetzt bei den gebräuchlichen Turbinen angewendet, sie werden aber dazuao which is also made of as fire-resistant material as possible. Similar signs made of the same material as the shovels are already in use Turbines are used, but they become so
*5 angewendet, die Schaufeln im richtigen Abstand zu halten oder überhaupt durch gegenseitige Verbindung zu einem festen Ganzen zusammenzuschließen. * 5 applied to hold the blades at the correct distance or even merge with mutual connection to a fixed whole.
Die Erfindung erstreckt sich nun darauf, zum Schütze des Laufrades und der Leit vorrichtung zwischen den Schaufeln einer Reihe und zwischen den Schaufelreihen selbst feuerfeste Platten einzubauen, und zwar in der Weise, daß die Befestigung derselben unabhängig von den Schaufeln durch eigene Befestigungsteile geschieht. Die Befestigung kann beispielsweise durch schwalbcnschwanzförmige Einsätze, durch Verzapfungen o. dgl. erfolgen. The invention now extends to the protection of the impeller and the Leit device between the blades of a row and between the rows of blades even to build refractory plates, in such a way that the attachment of the same is done independently of the blades by their own fasteners. The fastening can for example take place by means of dovetail-shaped inserts, tenons or the like.
Die Zeichnung stellt eine Ausführungsform dieser Erfindung dar Fig. 1 ist ein Querschnitt durch das Laufrad einer Turbine. Fig. 2 ist ein Schnitt der Fig. 1 nach Linie A-A, und Fig. 3 ist eine Aufsicht der Fig. 1.The drawing illustrates an embodiment of this invention. Figure 1 is a cross-section through the impeller of a turbine. FIG. 2 is a section of FIG. 1 along line AA, and FIG. 3 is a plan view of FIG. 1.
Es bedeutet α die eigentliche Schaufel, die durch eine schwalbenschwanzförmig ausgebildete Wurzel b am Radkranz c de? Laufrades befestigt ist. Zwischen den Schaufelreihen befindet sich ein aus feuerfestem Material bestehender Plattenbelag c. welcher imabhängig von den Schaufeln durch eigene, in diesem Falle schwalbenschwanzfürmig ausgebildete Teile f am Radkranz befestigt ist. Der Plattenbelag ist hierbei derart angeordnet, daß zwischen ihm und dem Radkranz ein Spiel- und Isolierraum g gebildet ist.It means α the actual blade, which is formed by a dovetail-shaped root b on the wheel rim c de? Impeller is attached. Between the rows of blades there is a paving made of refractory material c. which, depending on the blades, is attached to the wheel rim by its own, in this case dovetail-shaped parts f. The paving is arranged in such a way that a clearance and insulating space g is formed between it and the wheel rim.
Mehrere solcher in Fig. 2 dargestellten Platten können auch aus einem Stück hergestellt sein; sie können sogar alle vereinigt werden, so daß eine einzige Schutzhülle entsteht. Die Befestigung der Platten kann auch in der Weise geschehen, daß dieselbeSeveral such plates shown in Fig. 2 can also be made from one piece be; they can even all be united to form a single protective cover. The attachment of the plates can also be done in such a way that the same
