Description

Die Erfindurg betrifft eine Kreiselkranzabdichtung für mehrstufige Kreiselpumpen, deren Kreiselaggregate hintereinander auf eines- Achse in einem zylindrischen Gehäuse vorgesehen sind.The invention relates to a rotary ring seal for multi-stage Centrifugal pumps, their centrifugal units one behind the other on an axis in a cylindrical Housing are provided.

Die Erfindung beruht darin, daß die mit einem Schaufelrad vereinigten auf einer Achse A hintereinander in einem zylindrischen Gehäuse angeordreten Kreisel in bekannter Weise mit einer umlaufenden Ringnut versehen sind, in die ein federnder, selbstspannender Metallring nach Art eines Kolbenringes in Richtung der Innenfläche des zylindrischen Gehäuses eingebettet ist.The invention is based on the fact that they are combined with a paddle wheel gyroscopes arranged one behind the other on an axis A in a cylindrical housing are provided in a known manner with a circumferential annular groove in which a resilient, self-tightening metal ring in the manner of a piston ring in the direction of the inner surface of the cylindrical housing is embedded.

In der Zeichnung ist die Erfindung in den Fig. i bis 3 veranschaulicht.In the drawing, the invention is illustrated in FIGS.

Fig. i zeigt die erfindungsgemäße Anordnung in einer Draufsicht, wobei das zylindrische Gehäuse weggelassen ist; Fig. 2 zeigt die erfindungsgemäße Anordnung der Kreiselkranzabdichtung an einer mehrstufigen Kreiselpumpe in einem Querschnitt nach der Linie B-B in Pfeilrichtung I; Fig. 3 zeigt die Kreiselkranzabdichtung allein an der Angriffsstelle des zylindrischen Gehäuses.Fig. I shows the arrangement according to the invention in a plan view, wherein the cylindrical housing is omitted; Fig. 2 shows the arrangement according to the invention the rotary ring seal on a multistage centrifugal pump in a cross-section along the line B-B in the direction of arrow I; Fig. 3 shows the rotary ring seal alone at the point of attack of the cylindrical housing.

i ist das zylindrische Gehäuse der mehrstufigen Kreiselpumpe. 4 sind die mit einem Schaufelrad 3 verbundenen, auf der Achse A gelagerten Kreisei-. Erfindungsgemäß sind die Kreisel 4 an ihrem Umfange mit einer an sich bekannten Ringnut 5 versehen .(Fig. 2 und 3), in die ein in Richtung der Innenfläche 6 des zylindrischen Gehäuses i wirkender und an diese sich festklemmender, federnder und selbstspannender Metallring 7 nach Art eines Kolbenringes eingebettet ist. Zwischen dem Kreiselkranz und der Innenfläche 6 des zylindrischen Gehäuses i ist ein angemessenes Spiel vorhanden.i is the cylindrical housing of the multistage centrifugal pump. 4 are the rotary egg connected to a paddle wheel 3 and mounted on the axis A. According to the invention the gyroscopes 4 are provided on their circumference with an annular groove 5 known per se . (Fig. 2 and 3), in which one in the direction of the inner surface 6 of the cylindrical housing i acting and clamping, resilient and self-tightening metal ring 7 is embedded like a piston ring. Between the top and the There is adequate clearance on the inner surface 6 of the cylindrical housing i.

Die federnd in Richtung der Innenfläche 6 des zylindrischen Gehäuses i wirkenden und an diese sich festklemmenden Metallringe der Kreisel 4, in der Zeichnung sind es beispielsweise zwei Kreisel, haben den Zweck, daß während der Wirkung der Kreiselpumpe das von der Ansaugseite des Kreisels :1 in Pfeilrichtung II in dessen Schaufelrad 3 und über die Druckseite in den nächsten Kreisel 4 weitengeleitete, flüssige oder luftförmige Medium an einem ungewollten :*#Llstritt zN-,-isclieli der Gehäuseinnenfläche 6 und dem Metallring 7 gehindert wird.The resilient towards the inner surface 6 of the cylindrical housing i acting and clamped on these metal rings of the gyroscope 4, in the drawing if there are two gyroscopes, for example, the purpose is that during the action of the Centrifugal pump from the suction side of the centrifugal: 1 in the direction of arrow II in its Paddle wheel 3 and via the pressure side into the next gyro 4, liquid or air-like medium at an unwanted: * # Llstritt zN -, - isclieli the housing inner surface 6 and the metal ring 7 is prevented.
