Description
Luftzuführung in das Gehäuse von Freistrahlturbinen. Bei Freistrahlturbinen hat sich gezeigt, daß das aus der Turbine austretende Wasser stets schaumig ist, .also Luft mit sich führt. Sobald nun der Unterwasserspiegel hoch ansteigt, nimmt der bis nahe an den unteren Rand der Turbine austretende Wasserschaum Luft aus dem Gehäuse mit, so daß im Innernein Vakuum entsteht, wenn das Gehäuse luftdicht gebaut ist. Steigt aber der Wasser= spiegel derart, daß das keine Luft führende Wasser an den unteren Gehäuseflansch reicht, so tritt ein plötzliches Vollsaugen des ganzen Turbinengehäuses und damit ein Versagen der Turbine ein.Air supply into the housing of free jet turbines. With free jet turbines it has been shown that the water exiting the turbine is always foamy, .so carries air with it. As soon as the underwater level rises high, it increases the foam of water exiting up to the lower edge of the turbine is air out of the Housing with, so that a vacuum is created inside when the housing is built airtight is. But if the water level rises in such a way that the water does not carry any air reaches to the lower housing flange, the whole thing is suddenly soaked Turbine housing and thus a failure of the turbine.
Um dies zu verhindern, ist es nötig, daß in das Gehäuse Luft eingeführt wird, ohne daß die geschlossene Bauart, welche eine Aufstellung der Turbine im Maschinenraum selbst gestattet, dadurch Einbuße erleidet.To prevent this, it is necessary that air is introduced into the housing is without the closed design, which requires the installation of the turbine in the engine room himself permitted, thereby suffering losses.
Die vorliegende Erfindung zeigt nun die Zuführung der Luft durch eine hohle Welle, wobei es möglich ist, die Luftzuführung durch einen Deckel abzusperren.The present invention now shows the supply of air through a hollow shaft, whereby it is possible to shut off the air supply with a cover.
Die Zeichnung zeigt eine solche Luftzuführung im Schnitt. Bei a tritt die Luft in die hohe Welle ein und gelangt bei b in das Gehäuseinnere. Durch die Umdrehung des Laufrades wird die Luft durch die Zentrifugalkraft nach außen geschleudert, d. h. das Laufrad wirkt wie ein Ventilator. Diese Luftzuführung kann von einer oder von beiden Seiten der Welle erfolgen.The drawing shows such an air supply in section. At a occurs the air enters the high shaft and enters the inside of the housing at b. Through the Rotation of the impeller, the air is thrown outwards by the centrifugal force, d. H. the impeller acts like a fan. This air supply can be from one or done from both sides of the shaft.
