Description
Einlaufvorrichtung für oberschlächtige Wasserräder. Als Einlaufvorrichtung für oberschlächtige Wasserräder ist allgemein bekannt und benutzt die sogenannte Spannschütze im Zulaufgerinne (Abb. i), mittels der das Wasser in einer Parabelbahn (unter Einwirkung des Spanngefälles h und der Erdbeschleunigung auf dem Fallwege h-h) dem Rad zugeführt wird. Hierbei treten aber verschiedene-Mängel zutage. Sie bestehen darin, daß erstens das für ein gutes . Arbeiten des Rades stets erforderliche Spanngefälle nur bei richtiger Bedienung der Schütze vorhanden ist und unter Umständen bei mangelnder Bedienung stärk zurückgeht oder gar ganz verschwindet, daß zweitens stoßfreier Eintritt für genügend großen wasserhaltenden Bogen nicht zu erzielen ist, und daß drittens die Umfangsgeschwirndigkeit und damit die Drehzahl des Wasserrades im Verhältnis zu der absoluten Zutrittsgeschwindigkeit klein ist.Inlet device for overshot waterwheels. As an inlet device for overshot waterwheels is well known and uses the so-called Tension gates in the inlet channel (Fig. I), by means of which the water in a parabolic path (under the influence of the tension gradient h and the acceleration due to gravity on the fall path h-h) is fed to the wheel. Here, however, various deficiencies come to light. she consist in the fact that firstly this is for good. Work of the bike is always necessary Clamping gradient only exists if the contactors are operated correctly and under certain circumstances if it is not used, it decreases sharply or even disappears completely, and secondly Bump-free entry for a sufficiently large water-retaining arch cannot be achieved and that, thirdly, the peripheral speed and thus the speed of the water wheel is small in relation to the absolute speed of access.
Die in Abb.2 dargestellte neue Einlaufvorrichtung ist frei von diesen Mängeln. Sie besteht aus der nach unten gekrümmten oder auch geradlinig verlaufenden Leitbahn L mit einem vorgelagerten festen oder nachstellbaren Überlauf U, der in der verschiedensten Weise ausgebildet sein kann und hier z. B. durch eine drehbare Walzenschütze von halbkreisförmigem Querschnitt gebildet wird. Die Leitbahn bildet wasserabwärts bis zu einer gewissen Höhe h den Abschluß des Zulaufgerinnes und erzeugt somit ohne jede Bedienung einen Vorstau hl, der sowohl bei festem als auch bei nachstellbarem Überfall in dem Falle, daß eine sachgemäße Bedienung nicht besteht, noch genügt, um eine *genügend große Eintrittsgeschwindigkeit in das Rad zu erreichen.The new inlet device shown in Fig. 2 is free of these Flaws. It consists of the downward curved or straight line Conductor L with an upstream fixed or adjustable overflow U, which is in can be designed in various ways and here z. B. by a rotatable Roller gate is formed by a semicircular cross-section. The channel forms downstream of the water up to a certain height h the closure of the inlet channel and generated thus a Vorstau hl without any operation, both with fixed and adjustable Assault in the event that proper operation does not exist, nor is it sufficient, to achieve a sufficiently large entry speed into the wheel.
Da ferner das untere Ende der Leitbahn unter einem viel kleineren Winkel zu dem Radumfang gerichtet sein kann und deshalb der Eintritt in das Rad viel spitzwinkliger erfolgt als wie bei dem parabelförmigen Zutritt nach Abb, i, so ergibt sich auch bei erheblicher Umfangsgeschwindigkeit vollkommen oder doch angenähert stoßfreier Eintritt in das Rad. Bei richtiger Lage und Höhe der Leitbahn wird somit immer ein erheblich günstigerer Gang und auch besserer Nutzungsgrad des Rades erzielt.Furthermore, since the lower end of the interconnect is under a much smaller one Angle can be directed to the wheel circumference and therefore the entry into the wheel much more acute-angled than with the parabolic access according to Fig, i, this results in complete or at least in the case of considerable circumferential speed Approximately shock-free entry into the wheel. With the correct position and height of the guideway is therefore always a significantly cheaper gear and also a better degree of use of the Rades scored.
