LUDWIG KOESTER in FRANKENTHAL (Rheinpfalz). Turbinenventilation durch den Regulirschieber.LUDWIG KOESTER in FRANKENTHAL (Rheinpfalz). Turbine ventilation through the regulating slide.
Patentirt im Deutschen Reiche vom 13. Juni 1880 ab.Patented in the German Empire on June 13, 1880.
Gegenstand der vorliegenden Erfindung ist die Ventilation des Leitrades von Turbinen durch den Regulirschieber, welche in der Zeichnung sowohl an vertical wie horizontal laufenden Turbinen dargestellt ist. Das Laufrad ist mit A bezeichnet, das Leitrad mit B. The subject of the present invention is the ventilation of the stator of turbines through the regulating valve, which is shown in the drawing on both vertical and horizontal running turbines. The impeller is designated with A , the idler with B.
Die Leitradzellen sind zu je zwei sich gegenüberliegenden Segmenten zur Hälfte von oben, zur anderen Hälfte von der inneren Seite beaufschlagt. The stator cells are each two opposing segments half from above, applied to the other half from the inner side.
Für die Regulirung der Turbine dient ein winkelförmiger Ringschieber C, vermittelst welches die Turbine von ο bis 9/10 beaufschlagt werden kann.An angular slide ring C is used for the regulation of the turbine, by means of which can be applied to the turbine of ο to 9/10 min.
Die Verstellung des Ringschiebers erfolgt durch ein Zahnrad F, Fig. 1, und vermittelst einer Steuerwelle D, und zwar dreht sich dasselbe um den inneren Turbinenmantel G in bekannter Weise.The adjustment of the ring slide takes place by means of a gear F, Fig. 1, and by means of a control shaft D, namely the same rotates around the inner turbine casing G in a known manner.
Die Arme des Ringschiebers, sowie die Deckflächen desselben sind behufs der Ventilation mit zusammenhängenden Luftkanälen versehen, welche einerseits mit dem inneren Räume G der Turbine, andererseits mit den Leitradzellen in Verbindung stehen, versehen.The arms of the ring valve, as well as the top surfaces of the same are provided with connected air ducts for ventilation, which are connected on the one hand to the inner space G of the turbine and on the other hand to the stator cells.
Durch diese Kanäle stehen die geschlossenen Leitradzellen mit dem Räume G, also mit der freien Atmosphäre in Verbindung. Infolge davon herrscht in den Leitradzellen stets der Atmosphärendruck, was eine Ausgleichung von Spannungsdifferenzen bewirkt.Through these channels, the closed stator cells are in connection with room G, i.e. with the free atmosphere. As a result, atmospheric pressure always prevails in the stator cells, which balances out voltage differences.
Tritt z. B., Fig. 3, gespanntes Aufschlagwasser aus den Leitradzellen H nach den Laufradzellen J, so bewegt sich das Laufrad nach der Richtung des Pfeiles; die mit Wasser angefüllten Laufradzellen J gelangen daher, indem sie das Bestreben haben, sich zu entleeren, unter die durch den Schieber C geschlossenen Leitradzellen. In dem Mafse, wie sich das Wasser unter den geschlossenen Leitradzellen entleert, strömt Luft nach, welche den Raum des austretenden Aufschlagwassers einnimmt.Occurs z. B., Fig. 3, tensioned impact water from the stator cells H to the impeller cells J, so the impeller moves in the direction of the arrow; The impeller cells J , which are filled with water, therefore end up under the stator cells, which are closed by the slide C, because they tend to empty themselves. To the extent that the water empties under the closed stator cells, air flows in, which takes up the space of the emerging impact water.
Wäre die Turbine nicht ventilirt, so würde in den Leitradzellen H1 eine negative Spannung (Luftverdünnung) stattfinden, welche den Austritt des Wassers aus dem Laufrad erschwert und Unregelmäfsigkeiten in der Wasserbewegung, insbesondere eine Vermischung von Wasser und Luft hervorruft, welche die Ursache von Effectverlusten ist.If the turbine were not ventilated, a negative voltage (air dilution) would take place in the stator cells H 1 , which makes it difficult for the water to exit the impeller and causes irregularities in the movement of the water, in particular a mixing of water and air, which is the cause of loss of effect is.
Dies wird durch die Ventilation der Turbine verhindert, deren Eigenthümlichkeit darin besteht, dafs sie durch den Regulirschieber erfolgt.This is prevented by the ventilation of the turbine, the peculiarity of which is that that it takes place through the regulating slide.
Die Form des Regulirschiebers ist dabei unwesentlich. Derselbe kann ein einfacher, horizontaler, ein senkrechter Kreisschieber oder Winkelschieber sein.The shape of the regulating slide is immaterial. The same can be a simple, horizontal, be a vertical circular slide or angled slide.
