Description

Radialverdichter mit einander gegenläufigen Schaufelrädern Die Erfindung betrifft einen Radialverdichter mit einander gegenläufigen Schaufelrädern. Sie soll die Anpassung des Verdichters an Betriebsverhältnisse, die von den beim Bau des Verdichters angenommenen abweichen, erleichtern.Centrifugal compressor with impellers rotating in opposite directions The invention relates to a centrifugal compressor with impellers rotating in opposite directions. she should the adaptation of the compressor to the operating conditions that occurred during the construction of the Compressor's assumed differ, make it easier.

Bekanntes, einfaches und billiges Mittel zu solcher Anpassung ist bei nicht gegenläufigen Verdichtern ein Leitschaufelkranz vor oder hinter dem Laufrad.A well-known, simple and cheap means of such adaptation is in the case of non-counter-rotating compressors, a guide vane ring in front of or behind the impeller.

Bei Gegenlaufverdichtern würde ein passend justiertes Leitrad, das vor dem ersten oder hinter dem zweiten der einander gegenläufigen Räder angeordnet ist, nur teilweise, nämlich am Eintritt des ersten und am Austritt des zweiten Rades, Stöße verhindern; aber zwischen den Rädern würden Stöße dadurch nicht vermieden.In the case of counter-rotating compressors, a suitably adjusted stator that arranged in front of the first or behind the second of the opposing wheels is, only partially, namely at the entry of the first and at the exit of the second wheel, Prevent bumps; but this would not avoid shocks between the wheels.

Die Erfindung soll diesen Nachteil beheben. Sie besteht darin, daß zwischen den gegenläufig rotierenden Schaufelrädern ein am Gehäuse der Maschine festsitzendes Schaufelrad angeordnet ist.The invention is intended to remedy this disadvantage. It consists in that between the paddle wheels rotating in opposite directions on the housing of the machine fixed paddle wheel is arranged.

Eine derartige Konstruktion bringt eine wesentliche Verbilligung in der Herstellung von Turbomaschinen. Man kann auf diese Weise die Lagerhaltung an Schaufelrädern reduzieren, indem innerhalb eines bestimmten Betriebsbereiches gleiche Gebläselaufräder verwendet werden können und trotzdem die Anpassung der Laufräder an verschiedene Betriebsverhältnisse erreicht wird, wobei es nur noch nötig ist, einen in entsprechender Form abgeänderten Leitschaufelkranz zu verwenden, der wesentlich einfacher und billiger herzustellen ist als die Laufschaufelräder, die ja hohen Zentrifugalkräften ausgesetzt sind.Such a construction brings in a substantial reduction in price the manufacture of turbo machinery. One can take stocking this way Reduce paddle wheels by keeping the same within a certain operating range Fan impellers can be used and still adjust the impellers to different operating conditions is achieved, whereby it is only necessary, to use a guide vane ring modified accordingly, which is essential is easier and cheaper to manufacture than the impellers, which are tall Are exposed to centrifugal forces.

Die Zeichnung stellt die Erfindung beispielsweise dar, sie bedarf keiner Erläuterung. Es zeigt Fig. 1 einen Axialschnitt durch die wesentlichsten Teile eines Radialverdichters gemäß der Erfindung und Fig. 2 einen Schnitt durch den gleichen Verdichter quer zur Maschinenachse entsprechend der Linie II-II der Fig. 1.The drawing shows the invention, for example, it needs no explanation. 1 shows an axial section through the most important Parts of a radial compressor according to the invention and FIG. 2 shows a section through the same compressor transversely to the machine axis according to the line II-II of the Fig. 1.
