PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine Finksche drehbare Leitschaufel für Francis-Turbinen. The present invention relates to a Fink rotatable guide vane for Francis turbines.
Bei vorliegender Erfindung ist der Drehzapfen α außerhalb der lichten öffnung an der Spitze der Leitschaufel angebracht.In the present invention, the pivot α is attached outside the clear opening at the tip of the guide vane.
Durch diese Anordnung wird erreicht, daß der schädliche Raum zwischen Leitschaufel b und dem Laufrad c selbst bei völligem Schluß ίο fast gänzlich vermieden wird, ein Vorteil, wie er von keiner anderen Regulierung auch nur annähernd erreicht wird. "By this arrangement it is achieved that the harmful space between the guide vane b and the impeller c is almost entirely avoided even at a complete end, an advantage that no other regulation can even come close to. "
Die gezeichnete Schaufelstellung ist die normale, dagegen stellen die punktierten Linien die Schaufelstellung bei vollständigem Schluß dar.The drawn blade position is the normal one, whereas the dotted ones represent Lines represent the position of the blades at full close.
Es ist weiter bei vorliegender ErfindungIt is further with the present invention
noch möglich, die Regulierung je nach Wunsch durch den inneren Ring d, welcher als ganze Platte ausgebildet werden kann, oder den Ring e oder direkt an der Schaufel in der üblichen Weise zu betätigen..it is still possible to use the inner ring d, which can be designed as a whole plate, or the ring e, or directly on the shovel, to operate the regulation in the usual way.
Ferner ist in vorliegender Erfindung die Möglichkeit gegeben, den Bolzen/ nahe dem Drehzapfen α hindurchgehen zu lassen, wodurch erreicht wird, daß der Bolzen f den größten Wasserdruck der Leitschaufel b aufzunehmen hat und dadurch den Drehzapfen a entlastet.Furthermore, in the present invention the possibility is given to let the bolt / pass close to the pivot α , whereby it is achieved that the bolt f has to absorb the greatest water pressure of the guide vane b and thereby relieves the pivot a.
