Description

Abdichtung des Rotors gegenüber deit`'esfstehenden Rohrwänden elektrischer Wasserturbinen--Generatoren Bekanntlich werden Wasserturbinen gebaut, bei welchen der Rotor des direkt angetriebenen Generators den äußeren Abschluß des Wasserdurchlaufkanales bzw. Wasserrohres bildet. Zwischen dem sich drehenden Rotorkörper und der stillstehenden Wasserrohrwand werden hierbei Ringdichtungen vorgesehen, damit nicht durchsickerndes Wasser in den Generator gelangen kann. Diese Abdichtungen bringen. eine erhöhte Reibung und starke Abnützung mit sich.Sealing of the rotor against the side walls of the electrical pipe Water Turbines - Generators It is well known that water turbines are built in which the rotor of the directly driven generator is the outer closure of the water flow channel or water pipe forms. Between the rotating rotor body and the stationary one Ring seals are provided for the water pipe wall so that no seepage is possible Water can get into the generator. Bring these seals. an increased Friction and heavy wear with it.

Erfindungsgemäß werden derartige Ringdichtungen lagerartig ausgebildet und durch öl und Fett geschmiert, um kleine Reibung und geringe Abnützung zu erreichen.According to the invention, such ring seals are designed like bearings and lubricated by oil and grease to achieve low friction and low wear.

Die Abb. i zeigt die allgemeine Anordnung eines solchen Generators im Wasserkanal, und Abb.2 zeigt die grundsätzlichen Einzelheiten der Abdichtung.Fig. I shows the general arrangement of such a generator in the water channel, and Figure 2 shows the basic details of the seal.

In Abb. i ist i die Wasserturbine mit den Arbeitsflügeln 2 und Leitschaufeln 3.' Auf den Arbeitsflügeln 2 ist außen der Rotor des Generators 5 befestigt. 6 und 7 sind Teile des Wasserdurchlaufrohres; 8 und 9 sind die Abdichtungen des Generators gegenüber dem Wasserrohr.In Fig. I i is the water turbine with the working blades 2 and guide vanes 3. ' The rotor of the generator 5 is fastened on the outside of the working wings 2. 6 and 7 are parts of the water flow pipe; 8 and 9 are the seals of the generator opposite the water pipe.

In Abb. 2 ist i i das stillstehende Wasserrohr, welches den lagerartigen Ring 12 trägt. An dem Rotor des Generators ist ein Ring 13 angesetzt, der zusammen mit dem Ring 12 die Abdichtung bildet. 16 und 17 sind ölzu-und -ablaufkanäle. i q. und i § sind mit Fett gefüllte Abdichtrillen. Die Wirkungsweise der Anordnung ist folgende: Da die lagerartigen Abdichtungen 8 und 9 bzw. 12 und 13 nicht den genauen Lauf eines wirklichen" Lagers erreichen können, sind die ölzirkulationsrillen 16 und 17 vorgesehen. Um das Austreten des Schmieröles an beiden Seiten der Dichtung zu vermeiden, wird gegebenenfalls noch an jeder Seite der Abdichtung die Rille 1:l bzw. 15 vorgesehen, die mit Fett u. dgl. gefüllt ist, um ein Austreten des Schmieröles zu vermeiden.In Fig. 2 ii is the stationary water pipe which carries the bearing-like ring 12. A ring 13 is attached to the rotor of the generator and, together with the ring 12, forms the seal. 16 and 17 are oil inlet and outlet channels. i q. and i § are sealing grooves filled with grease. The mode of operation of the arrangement is as follows: Since the bearing-like seals 8 and 9 or 12 and 13 cannot achieve the exact running of a real "bearing, the oil circulation grooves 16 and 17 are provided. In order to prevent the lubricating oil from escaping on both sides of the seal If necessary, the groove 1: 1 or 1 5 , which is filled with grease and the like, is provided on each side of the seal in order to prevent the lubricating oil from escaping.
