Strahlrad.Jet wheel.
Die Erfindung ist auf beiliegender Zeichnung in Fig. ι in einem senkrechten Schnitt bei theilweiser Seitenansicht dargestellt, während Fig. 2, 3 und 4 in gröfserem Mafsstabe Einzelheiten zeigen.The invention is shown in the accompanying drawing in Fig. Ι in a vertical section shown in partial side view, while Figs. 2, 3 and 4 show details on a larger scale demonstrate.
Das Strahlrad A ist in einem schneckenförmigen Gehäuse B, ähnlich den Ventilatorengehäusen angeordnet und in der Umfangswandung dieses Gehäuses B sind eine oder mehrere den Wasserstrahl zuleitende Düsen C angeordnet. The jet wheel A is arranged in a worm-shaped housing B, similar to the fan housing, and one or more nozzles C that feed the water jet are arranged in the circumferential wall of this housing B.
Am Umfange des Strahlrades A sitzen gleichmäfsig vertheilt die Schaufeln S, welche in den Fig. 2 und 4 in gröfserem Mafsstabe in Längsschnitt und Oberansicht dargestellt sind. Dieselben bestehen aus einem Metallbecken a von schaufelartigem Umfifs mit vorn und seitlich allmälig nach oben verlaufendem Rande b, hinten dagegen ziemlich steil aufwärts geknickter Wand c und einer keilartigen, nach vorn zugeschärften Erhöhung in der Mitte.At the circumference of the jet wheel A , the blades S sit evenly distributed, which are shown in FIGS. 2 and 4 on a larger scale in longitudinal section and top view. These consist of a metal basin a with a shovel-like circumference with the front and side edge b running gradually upwards, while the rear wall c is rather steeply bent upwards and a wedge-like elevation in the middle that is sharpened towards the front.
An diesem Schaufelkörper sitzen nach hinten zwei gleiche und parallele Lappen f, welche lang genug sind, um zwei Schrauben oder Niete darin anbringen zu können, womit diese Lappen, also die ganzen Schaufeln auf der Radscheibe A, befestigt werden, welch letztere dann zwischen den beiden Lappen f gefafst wird und noch etwas durch den hinteren, in der Mitte hug durchbrochenen Rand c der Schaufel nach dem Schaufelinnern hin vortritt. At the rear of this blade body sit two identical and parallel tabs f, which are long enough to be able to attach two screws or rivets, with which these tabs, i.e. the entire blades on the wheel disk A, are attached, which latter then between the two flap is gefafst f and anything else by the rear, hug in the middle perforated edge of the blade after the blade interior c vortritt out.
Auf der unteren Fläche der Schaufel ist noch eine nasenartige Rippe h angebracht, welche sich mit ihrer hinteren Kante gegen den Umfang des Rades A anlegt und so der Schaufel beim Aufprallen des Wassers noch als Stütze dient.On the lower surface of the shovel there is also a nose-like rib h , which rests with its rear edge against the circumference of the wheel A and thus serves as a support for the shovel when the water hits it.
Die Schaufeln werden so montirt, dafs die Lappen f radial stehen und ihre hintere Wand c sich dem Umfang des Rades anpafst, also die Schaufel selbst etwas schräg zum Radumfang gerichtet ist, derart jedoch, dafs ihr Vorderrand b parallel zu dem durch die entsprechenden Lappen f gehenden Radius von A gerichtet ist, also einen tangential zum Radumfang gerichteten Wasserstrahl senkrecht auffängt.The blades are mounted so that the tabs f are radial and their rear wall c adapts to the circumference of the wheel, i.e. the blade itself is directed somewhat obliquely to the circumference of the wheel, but in such a way that its front edge b is parallel to that formed by the corresponding tabs f going radius of A is directed, so it catches a water jet directed tangentially to the wheel circumference perpendicularly.
Die Strahldüse C findet, in einem Stutzen D am Umfange des Gehäuses B Aufnahme. Die Düse hat die Form eines Cylinders mit unten kegelförmig verjüngtem Ende, das durch eine Querwand i bis auf eine schmale, gebogene, mond- oder sichelförmig gestaltete Mündung k abgeschlossen ist; die Wandung ist jedoch noch nach unten über i hinaus rinnenartig verlängert und abgeschnitten, damit das austretende Wasser an der äufseren, vom Turbinenrad A abgewendeten Seite in der Leitschaufel b seine Begrenzung und Führung findet, während in der Richtung auf die Schaufeln und das Rad A hin die Wand fehlt.The jet nozzle C is accommodated in a connection D on the circumference of the housing B. The nozzle has the shape of a cylinder with a conically tapered end which is closed by a transverse wall i except for a narrow, curved, moon-shaped or sickle-shaped mouth k ; the wall is, however, lengthened and cut off like a channel downwards beyond i , so that the escaping water finds its limitation and guidance on the outer side facing away from the turbine wheel A in the guide vane b , while in the direction towards the vanes and the wheel A the wall is missing.
Diese Düse C wird im Stutzen D gehalten durch ein auf D geschraubtes T-Stück E, dessen seitlicher Stutzen m an das Wasserzufuhrrohr anschliefst, während der obere Stutzen η durch einen Deckel F mit Stopfbüchse 0 und Spindelbock ρ geschlossen ist.This nozzle C is held in connection D by a T-piece E screwed onto D , the side connection m of which connects to the water supply pipe, while the upper connection η is closed by a cover F with a stuffing box 0 and spindle bracket ρ .
Durch diesen Spindelbock ρ und die Stopfbüchse 0 geht die Spindel q des Ventiles r, welches unten im verjüngten Ende des Kör-The spindle q of the valve r, which is located at the bottom in the tapered end of the body, goes through this spindle bracket ρ and the stuffing box 0.
