Patentirt im Deutschen Reiche vom 23.. October 1891 ab.Patented in the German Empire on October 23, 1891.
Vorliegende Erfindung betrifft die Regelung von Vollturbinen mit innerer Beaufschlagung (sogen. Radialturbinen), bei denen diese Regelung durch achsiale Verstellung des Leitrades bewirkt wird. Der Zweck der Neuerung besteht darin, den Reactionsdruck des aus den Leitkanälen austretenden Wassers zur Unterstützung der Verstellung des Leitrades im Sinne der Verkleinerung der Kanäle dienstbar zu machen. Hierzu wird dem Leitrad eine Führung durch Schraubengewinde gegeben, welche solche Steigungsrichtung haben, dafs die jenem Reactionsdruck entsprechende und durch ein Stellzeug zu bewirkende Drehung des Rades eine achsiale Verstellung desselben in derjenigen Richtung herbeiführt, welche zu der besagten Verkleinerung erforderlich ist.The present invention relates to the regulation of full turbines with internal loading (so-called radial turbines), in which this control is achieved through axial adjustment of the stator is effected. The purpose of the innovation is to control the reaction pressure of the Guide channels escaping water to support the adjustment of the stator in the sense to make the downsizing of the channels serviceable. For this purpose, the stator is a guide given by screw threads, which have such a direction of inclination that the that Reaction pressure corresponding rotation of the wheel to be effected by a control tool an axial adjustment of the same in the direction that leads to the said reduction is required.
Eine diesem Zweck entsprechende Anordnung ist in beiliegender Zeichnung dargestellt. Bei derselben ist das die Schaufeln / tragende Leitrad B der Turbine A mit seiner Nabe auf eine feststehende Schraubenspindel D geschraubt, die durch Arme gestützt wird, welche von der festen Ringplatte C auslaufen. Die unteren, über das Turbinenrad hinausragenden Enden der Leitschaufeln I sind lose von einem Winkelring g umgeben, welcher drehbar auf der Platte C gelagert ist, und der innen die in die Leitkanäle des Rades B hineinragenden Leitklötze k trägt, während derselbe aufsen mit Schneckenzähnen versehen ist, in welche die Schnecke s eingreift. Eine durch ein geeignetes Triebwerk zu veranlassende Drehung dieser Schnecke wird somit eine Drehung des Ringes g herbeiführen, während die als Mitnehmer auf die Leitschaufeln / wirkenden Klötze k die Bewegung auf das Leitrad übertragen, welches sich dabei auf der Spindel D herunter- oder hinaufschraubt, so dafs im ersteren Falle die Austrittskanä'le verkleinert, im letzteren Falle vergröfsert werden.An arrangement corresponding to this purpose is shown in the accompanying drawing. In the same, the blades / bearing stator B of the turbine A is screwed with its hub onto a fixed screw spindle D , which is supported by arms which extend from the fixed ring plate C. The lower ends of the guide vanes I , which protrude beyond the turbine wheel, are loosely surrounded by an angular ring g , which is rotatably mounted on the plate C , and which inside carries the guide blocks k protruding into the guide channels of the wheel B , while the latter is provided with worm teeth on the outside in which the snail s engages. A rotation of this screw caused by a suitable drive mechanism will thus cause a rotation of the ring g , while the blocks k acting as drivers on the guide vanes / blocks transfer the movement to the guide wheel, which is screwed up or down on the spindle D, see above that in the former case the outlet canals are made smaller, in the latter case they are enlarged.
Bei dem zum Verkleinern der Leitkanäle erforderlichen Herunterschrauben des Leitrades mufs nun der gegen das Rad wirkende Wasserdruck (s. Pfeilex) überwunden werden. Andererseits ist der Reactionsdruck des aus dem Leitrad austretenden Wassers bestrebt, das Rad in der Richtung R dieses Druckes zu drehen. Giebt man daher dem Gewinde der Spindel D eine derartige Steigungsrichtung, dafs zur Verkleinerung der Leitkanäle das Leitrad in der Richtung R gedreht werden mufs, so unterstützt der Reactionsdruck die auf Verkleinerung gerichtete Verstellung des Rades, und es bedarf (abgesehen von Reibungswiderständen) zur besagten Verstellung nur der Ueberwindung der Differenz der Wirkung der beiden Kräfte auf das Stellzeug.When the guide wheel is screwed down, which is necessary to reduce the size of the guide channels, the water pressure acting against the wheel (see Pfeilex) must now be overcome. On the other hand, the reaction pressure of the water emerging from the stator tends to turn the wheel in the direction R of this pressure. If, therefore, the thread of the spindle D is given such a pitch direction that the guide wheel must be turned in the direction R in order to reduce the size of the guide channels, the reaction pressure supports the adjustment of the wheel aimed at reducing it, and it is necessary (apart from frictional resistance) for said adjustment only the overcoming of the difference in the effect of the two forces on the setting tool.
Bei der in der Zeichnung angenommenen links umlaufenden Turbine mufste zu diesem Zweck die Spindel Rechtsgewinde erhalten.In the case of the left rotating turbine assumed in the drawing, it had to be connected to this Purpose of getting the spindle right-hand thread.
Claims (1)
drehen läfst.that the guide wheel is guided by screw threads which have such a direction of inclination that the reaction pressure of the water jets emerging from the guide channels tries to turn the guide wheel in the sense of reducing the size of the channels and therefore supports the adjustment of the wheel counter to the axial water pressure, in conjunction with a die Ring (g) surrounding the guide vane ends and acting on the same by means of drivers, which extends through a
turn.
