PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Reguliervorrichtung für Kegelturbinen radialaxialer Bauart und besteht darin, daß für den kegelförmigen Leitapparat Finksche drehbare Leitschaufeln verwendet werden, deren drehbare Zapfen ebenfalls in einer Kegelfläche liegen. Es kann in mehreren Fällen, besonders wenn es sich darum handelt, in eine vorhandene Turbinenkammer eine neue Turbine mit drehbaren Schaufeln einzulegen, von großer praktischer Bedeutung sein, die Leitschaufeln in dieser Weise anzuordnen. Dadurch erhält man nämlich einen ausreichenden Durchströmungsquerschnitt für den Schaufeleinlauf, wobei man bei dieser Schrägstellung der Schaufel leichter die Geschwindigkeit der Turbine höher treiben kann, als es bei den gewöhnlichen Francisturbinen möglich ist.The invention relates to a regulating device for cone turbines of radial-axial type and consists in the fact that for the conical diffuser Finksche rotatable guide vanes are used whose rotatable pins are also in a conical surface. It can happen in several cases, especially when It is a matter of installing a new turbine with rotatable in an existing turbine chamber Inserting vanes, of great practical importance, the guide vanes in to arrange in this way. As a result, a sufficient flow cross-section is obtained for the blade inlet, whereby it is easier to determine the speed of the Turbine can drive higher than is possible with ordinary Francis turbines.
Fig. ι der Zeichnung zeigt einen axialen Schnitt durch eine solche Turbine. Auf den zwei Seiten der Figur sind zwei verschiedene an sich bekannte Anordnungen für die Umstellung der Leitschaufeln gezeigt. Fig. 2 zeigt die rechts dargestellte Umstellungsan-Ordnung von oben gesehen.Fig. Ι of the drawing shows an axial Section through such a turbine. On the two sides of the figure are two different ones Known arrangements for moving the guide vanes are shown. Fig. 2 shows the rearrangement arrangement shown on the right, seen from above.
Das Laufrad ist mit α und die Leitschaufeln mit b bezeichnet. Die Umdrehungszapfen c der letzteren liegen in einer Kegel fläche, deren Scheitelpunkt d ist. Die Flächen e bezw. f, an denen die Schaufelenden anliegen, sind Kegelflächen mit dem Zentrum im Punkt d. Die Umstellungseinrichtung kann, wie auf der linken Seite der Fig. I angedeutet, aus einem um die Leitradachse drehbaren Zahnrad g gebildet werden, dessen Zähne mit den Zähnen h eines kleinen Zahnsegmentes auf jeder Schaufei in Eingriff stehen. Das Zahnrad g kann auf bekannte Weise bewegt werden.The impeller is designated with α and the guide vanes with b . The rotation pin c of the latter are in a conical surface, the vertex of which is d. The surfaces e respectively. f, on which the blade ends rest, are conical surfaces with the center at point d. The conversion means may, as shown on the left side of Fig. I indicated, are formed of a rotatable about the Leitradachse g gear whose teeth with the teeth of a small h toothed segment on each blade or vane are engaged. The gear wheel g can be moved in a known manner.
Auf der rechten Seite der Fig. 1 ist eine Umstellungseinrichtung, bestehend aus einem Ring /, gezeigt, welcher durch kurze Gelenkstücke m mit jeder Schaufel verbunden ist, die Zapfen ^1 und t% dieser Gelenkverbindung sind radial gegen das Zentrum d gerichtet. Der Ring wird durch eine Welle η mit dem Arm 0 gedreht, welcher mit einem Zapfen p. zwischen zwei Vorsprüngen r am Ring hinabgreift. .On the right-hand side of FIG. 1, a changeover device consisting of a ring / is shown, which is connected to each blade by short joint pieces m , the pins ^ 1 and t % of this joint connection are directed radially towards the center d . The ring is rotated by a shaft η with the arm 0, which with a pin p. reaching down between two projections r on the ring. .
