Description
Die nekannten Flügerlader, insbesondere die für Meßzwecke verwendeten, ergeben (bei stark unterschiedlichen Durchflußgeschwindigktein gleicher Volumen keine kostanten Umdrehungszahlen. Je mehr sich die Durchflußgeschwindigkeit dem Wert Null nähert, desto unterschiedlicheer sind die Umdrehungszahlen gegenüber einer hüheren Durchflußgeshwindigkeit trotz gleichen Volumens, wodurch die Anwendung des Flügerrades für beispielsweise Meßzwecke beschränkt ist. The new known wing loaders, especially those used for measuring purposes, result in the same volume at very different flow rates no constant number of revolutions. The more the flow rate the When the value approaches zero, the more different the number of revolutions are compared to one higher flow rate despite the same volume, whereby the application of the Impeller is limited for example for measuring purposes.
Durch die Erfindung wird die allgemeine Anwendbarkeit des Flügelrades beispielsweise für Meßzwecke möglich. Dies wird dadurch erreicht, daß das federnd angebrachte Flügelrad bei zunehmender Strömungsgeschwindigkeit axial verschoben wird und die Rohrinnenwand einen von der Ausgangsstellung ,des Flügelrades an zunehmenden Querschnitt hat. Unter bestimmten Druckverhältnissen wird die Wirkung Ider Feder durch das Eigengewicht des Flügelrades bei beispielsweiser senkrechter Anordnung der Flügelradachse erreicht. The invention increases the general applicability of the impeller possible for measuring purposes, for example. This is achieved in that the resilient attached impeller axially displaced with increasing flow velocity and the inner wall of the pipe increases from the starting position of the impeller Has cross-section. Under certain pressure conditions the effect of the spring becomes due to the weight of the impeller in the case of a vertical arrangement, for example reached the impeller axis.
Bei Anordnung eines relativ zur Rohrachse festen Flügelrades vergrößert ein axial gegen Federkraft verschiebbarer Teil (den freien Querschnitt bei zunehmender Strömung. Auch hier wird unter bestimmten Druckverhältnissen die Wirkung der Feder durch das Eigengewicht Ides beweglichen Teils (bei beispielsweiser senkrechter Anordnung der Flügeiradachse erreicht. When an impeller is arranged that is fixed relative to the pipe axis, it is enlarged a part that can be moved axially against spring force (the free cross-section with increasing Flow. Here, too, the effect of the spring is increased under certain pressure conditions due to the dead weight of the movable part (for example with a vertical arrangement reached the wheelchair axis.
Bei ebenfalls relativ zur Rohrachse festem Flügelrad wird die Vergrößerung des freien Querschnittes durch eine elastiche Rohrwandung erreicht, wobei die Kammer 8 in Verbindung mlit dem ausströmenden Medium steht. If the impeller is also fixed relative to the pipe axis, the magnification is of the free cross-section is achieved through an elastic tube wall, the chamber 8 is in connection with the outflowing medium.
Die Erfindung ist in vier Abhilidungen beispielsweise dargestellt. The invention is illustrated in four modifications, for example.
Abb. I zeigt ein fest gelagertes Flügelrad I mit der Welle 2 und den Lagern 3 in einem Gehäuse 4. Fig. I shows a fixedly mounted impeller I with the shaft 2 and the bearings 3 in a housing 4.
Die Turbine 1 ist axial gegen eine Feder verschiebbar. The turbine 1 is axially displaceable against a spring.
Ablb. 2 zeigt eine Turbine 1, deren Lagerung 3a und 3o gegen Federdruck verschiebbar list. Aus beiden Abbildungen ist die Querschnittsvergrößerung gegenüber der gezeigten Ausgangsstellung der Turbine ersichtlich. Fig. 2 shows a turbine 1, the bearings 3a and 3o thereof against spring pressure movable list. The cross-sectional enlargement is opposite from both figures the shown starting position of the turbine can be seen.
Abb. 3 zeigt ein fest gelagertes Flügelrad 1 in einem Gehäuse 4 Der Teil 6 ist gegen Federkraft .axial verschiebbar. Fig. 3 shows a fixedly mounted impeller 1 in a housing 4 The Part 6 is axially displaceable against spring force.
Abb. 4 zeigt ein fest gelagertes Flügelrad 1 in einem Gehäuse 4. Die Innenwandung 7 ist elastisch, und die Kammer 8 steht durch eine Bohrung g mit dem ausströmenden Medium in Verbindung. Fig. 4 shows a fixedly mounted impeller 1 in a housing 4. The inner wall 7 is elastic, and the chamber 8 stands with a bore g in connection with the outflowing medium.
Die Richtung des Durchflusses ist durch Pfeile angegeben. The direction of the flow is indicated by arrows.
