Description
Flügelrad für Wassermesser. Bei den bisher bekannt gewordenen Flügelrad-Wassermessern haben die Flügel des Flügelrades alle die gleiche Länge, d. h. ihre äußeren Begrenzungslinien liegen alle auf einer zu der Achse des .Flügelrades konzentrischen Zylinderfläche. Die Anzeigeresultate solcher Flügel sind bei kleinen Durchflußmengen nicht einwandfrei. Es hat sich nun gezeigt, daß diese Resultate bedeutend verbessert werden können, wenn man eine Anzahl der Flügel kürzer macht wie die anderen. Dieses bildet den Gegenstand der vorliegenden Erfindung.Impeller for water knife. In the case of the impeller water meters that have become known so far the blades of the impeller are all the same length, i.e. H. their outer boundary lines all lie on a cylindrical surface which is concentric to the axis of the impeller. The display results of such wings are not perfect with small flow rates. It has now been shown that these results can be significantly improved if you make a number of the wings shorter than the others. This makes that Subject of the present invention.
Auf der Zeichnung ist eine Ausführungsform der Erfindung bei einem Mehrstrahlmesser zur Darstellung gebracht worden, und zwar zeigt Abb. i einen wagerechten Schnitt nach Ebene A-B der Abb. z eines Meßgehäuses mit Flügelrad. Abb. 2 ist ein senkrechter Schnitt nach Ebene C-D der Abb. i.In the drawing, an embodiment of the invention is at a Multi-beam knife has been shown, namely Fig. I shows a horizontal one Section along plane A-B in Fig. Z of a measuring housing with an impeller. Fig 2 is a vertical section according to plane C-D of Fig. i.
In dem Meßgehäuse a, welches in diesem Fall acht auf dem Umfang verteilte Einflußöffnungen c und ebenso viele Ausflußöffnungen h besitzt, dreht sich das Flügelrad d. Das letztere hat bei der dargestellten Ausführungsform zehn radiale Flügel, von denen fünf (e) beinahe bis an die innere Umfläche des Gehäuses a reichen, während die dazwischenliegenden fünf Flügel (f) etwas weiter von der Gehäuseinnenwand abstehen wie ihre Nachbarn.In the measuring housing a, which in this case has eight inflow openings c distributed around the circumference and the same number of outflow openings h, the impeller d rotates. In the embodiment shown, the latter has ten radial wings, five (e) of which extend almost to the inner surface of the housing a, while the five wings (f) in between protrude somewhat further from the inner wall of the housing than their neighbors.
Es ist klar, daß die Anzahl der Zu- und Abflußöffnungen sowie die Anzahl der Schaufeln des Flügelrades andere sein können wie in dem dargestellten Beispiel.It is clear that the number of inlet and outlet openings as well as the Number of blades of the impeller can be other than that shown Example.
Es hat sich jedoch gezeigt, daß besonders günstige Resultate erzielt wurden, wenn die Anzahl der Flügel des Flügelrades größer war als die Anzahl der Einflußlöcher.However, it has been shown that particularly favorable results are achieved were when the number of blades of the impeller was greater than the number of Influence holes.
