KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die bekannten Flügelrad-Wassermesser zeigen den Nachteil, daß sie kleine durchströmende
Wassermengen sehr ungenau messen oder gar nicht mehr anzeigen.
Die vorliegende Erfindung ist bestimmt, diesem Fehler abzuhelfen.The known impeller water meters have the disadvantage that they measure small amounts of water flowing through very inaccurately or no longer display them at all.
The present invention is intended to remedy this error.
In Fig. ι ist ein Querschnitt des Flügelrades mit einem Teil des Gehäuses dargestellt, in Fig. 2 ein Schnitt senkrecht zur Flügelradachse. In Fig. Ι a cross section of the impeller is shown with part of the housing, in Fig. 2 a section perpendicular to the impeller axis.
Durch die Bohrungen α tritt das Wasser ein, und zwar in tangentialer Richtung, um
die Flügel f möglichst senkrecht zu treffen; durch die Bohrungen b tritt es wieder aus.
Während in den bekannten Flügelrad-Wassermessern, bei kleinen Wassermengen und dementsprechend geringer Eintrittsgeschwindigkeit
in den Kanälen a, das Wasser zwischen den Flügeln von α nach b übertreten konnte,
'20 ohne eine Bewegung des Rades hervorzurufen, muß bei der vorliegenden Anordnung das
Wasser, durch die Rippe d und den Rand e (Fig. 1) vom Ausströmraum getrennt, das
Flügelrad etwas heben, um sich den Durchfluß zu ermöglichen. Diese Hubbewegung des
Rades sowie die dadurch bewirkte Entlastung des Spurzapfens der Flügelradachse begünstigt
das Bestreben des einströmenden Wassers, das Flügelrad in Drehung zu versetzen.The water enters through the bores α , namely in a tangential direction in order to meet the wings f as perpendicularly as possible; it exits again through the bores b.
While in the known impeller water meters, with small amounts of water and correspondingly low entry speed in the channels a, the water between the blades from α to b could pass without causing the wheel to move, in the present arrangement the water must pass through the rib d and the edge e (Fig. 1) separated from the discharge space, lift the impeller a little to allow the flow. This lifting movement of the wheel as well as the resulting relief of the spur pin of the impeller axle favors the efforts of the inflowing water to set the impeller in rotation.
Die Drehbewegung tritt schon bei einer Wassermenge ein, deren Stoßwirkung beim Auftreffen auf das Flügelrad noch nicht genügen würde, das Rad in Bewegung zu setzen.The rotary motion already occurs with a quantity of water whose impact effect with Hitting the impeller would not be enough to set the wheel in motion.
Der Wassermesser nach vorliegender Erfindung ist also empfindlicher und zeigt schon bei geringeren Wassermengen den Verbrauch an als die bisher bekannten.The water meter according to the present invention is therefore more sensitive and already shows at lower water quantities the consumption than the previously known.
