Description
Es ist bekannt, daß z. B. Francisturbinen mit radialer Beaufschlagung mit Finkscher Drehschaufelregulierung gebaut werden.It is known that e.g. B. Francis turbines with radial admission be built with Finkscher rotary blade regulation.
Die Drehschaufelregulierung hat jedoch den bekannten Nachteil, daß der Eintrittswinkel des Wassers vom Leitrad in das Laufrad beim Schließen der Schaufeln zum Nachteil für den Wirkungsgrad sich ändert. Die Leitschaufeln werden immer mehr vom Laufrad em@tfernt, das Wasser geht zum Teil am Laufrad vorbei, wodurch der Wit'kungsgrad bei halber Beaufschlagung der Turbine so rasch abnimmt, daß für diesen Fall eine Wh-kungsgradgarantie, wie allgemein bekannt ist, nicht mehr gewährt wird.However, the rotary vane regulation has the known disadvantage that the angle of entry of the water from the diffuser into the impeller when the blades are closed to the detriment of the efficiency changes. There are more and more guide vanes removed from the impeller, the water partly bypasses the impeller, which increases the degree of whitewater when the turbine is half loaded so rapidly that a Wh-degree guarantee, as is generally known, is no longer granted.
Die Erfindung bezieht sich daher auf ein Leitschaufelsystem, bei dem der Eintrittswinkel des Wassers vom Leitapparat .in das Laufrad unfehlbar gleichbleiben muß und eine Entfernung der beweglichen Leitschaufel vom Laufrad nicht stattfinden kann, der Wirikungsgrad also bei jeder Einstellung der Regulierung gleichbleiben muß.The invention therefore relates to a guide vane system in which the angle of entry of the water from the diffuser into the impeller will inevitably remain the same does not have to take place and a removal of the movable guide vane from the impeller can, so the degree of effectiveness remains the same with each adjustment of the regulation got to.
Der Erfindungsgegenstam.d ist beispielsweise für eine Francisturbine in der Zeichnung im Aufriß und Grundriß je im Schnitt dargestellt.The subject matter of the invention is for a Francis turbine, for example in the drawing in elevation and plan each shown in section.
Auf einem Tragring a, der mit dem Mauerwerk verbunden ist, ist der Leitapparat, bestehend aus zwei Schaufelteilen b und c, so angeordnet, daß die Schaufelteile b fest mit dem Tragring verbunden sind, während die Schaufelteile c mit dem Regulierring q derart verbunden sind, daß sie mittels der am Ring angegossenen Laschen r und dem im Turbinenbau bekannten Gestänge, auf dem Tragring gleitend, geöffnet und geschlossen werden können. Im Grundriß zeigen vier Leitschaufeln o die geöffnete Stellung, zwei Leitschaufeln lt die halb geöffnete, zwei Leitschaufeln e die ein viertel geöffnete und zwei Leitschaufeln g die geschlossene Stellung. Der äußere Teil der Leitschaufeln c greift in geschlossenem Zustand noch ein Stück über die Leitschaufel b hinüber, wodurch der Eintritt des Wassers in das Laufrad verhindert ist.On a support ring a, which is connected to the masonry, is the Diffuser, consisting of two vane parts b and c, arranged so that the vane parts b are firmly connected to the support ring, while the blade parts c with the regulating ring q are connected in such a way that they r and by means of the tabs cast on the ring the linkage known in turbine construction, sliding on the support ring, open and closed can be. In the plan, four guide vanes show the open position, two Guide vanes is the half-open, two guide vanes and the quarter-open and two guide vanes g the closed position. The outer part of the guide vanes In the closed state, c reaches a little over the guide vane b, whereby the entry of the water into the impeller is prevented.
Der Laufraddeckel p schließt, an den Leitschaufeln@ b befestigt, die Zwischenräume von einer Leitschaufel zur anderen Leitschaufel nach oben ebenfalls ab.The impeller cover p closes, attached to the guide vanes @ b, the Gaps from one guide vane to the other upwards too away.
