Description
Die erfindungsgemäße Anordnung ist auch in Kombination mit anderen Regelungsarten verwendbar, wie z, B, mit der Drehzahl- oder Dralldrossel-Regelung, Dadurch können unter Umständen noch bessere Ergebnisse erzielt werden,The arrangement according to the invention is also shown in Can be used in combination with other types of control, e.g. with speed or swirl throttle control, In this way, even better results can be achieved under certain circumstances.
Die Erfindung wird an Hand der schematischen Zeichnung näher erläutert, die den wesentlichen Teil der erfindungsgemäßen Anordnung im Axialschnitt darstellt. The invention is explained in more detail with reference to the schematic drawing, which represents the essential part of the arrangement according to the invention in axial section.
Das zweiflutige Laufrad I besteht aus einer Rad- »o scheibe 2, die Laufschaufeln 3 der ersten (inneren) Flut trägt und mit einer die Laufschaufeln 4 der zweiten (äußeren) Flut tragenden Deckscheibe 5 abgedeckt ist. Die Laufschaufeln 4 der zweiten Flut sind mit einer zusätzlichen Deckscheibe 6 abgedeckt, xsThe double-flow impeller I consists of a wheel »o washer 2, the blades 3 of the first (inner) flow carries and with one the blades 4 of the second (outer) flood-bearing cover disk 5 is covered. The blades 4 of the second tide are covered with an additional cover disk 6, xs
Die beiden Laufschaufelsysteme 3 und 4 bilden somit zusammen mit der Radscheibe 2 und der Deck scheibe 5 bzw. 6 ein inneres Teilrad 7 und ein äuße res Teilrad 8. The two rotor blade systems 3 and 4 thus form, together with the wheel disk 2 and the cover disk 5 and 6, an inner part wheel 7 and an outer part wheel 8.
Die Saugleitung 9 des zweiflutigen Laufrades 1 ist axial angeordnet. Dicht vor dem Eintritt in die Laufschaufelkanäle ist in der Wandung quer zur Strömung eine Blende 11 mit verstellbarer öffnung angeordnet, deren Mittelpunkt in der Laufradachse liegt. Am Laufradaustritt 12 ist ein Ringdiffusor mit einer festen 13 und einer verschiebbaren Wand 14 angeordnet.The suction line 9 of the double-flow impeller 1 is arranged axially. A diaphragm 11 with an adjustable opening, the center of which lies in the impeller axis, is arranged in the wall transversely to the flow just before the entry into the rotor blade channels. A ring diffuser with a fixed 13 and a movable wall 14 is arranged at the impeller outlet 12.
Wenn die Blende Il voll geöffnet ist und die verschiebbare Diffusorwand 14 in der mit voll ausgezogenen Linien dargestellten Lp^e steht, kann das Arbeitsmittel den ganzen Querschnitt der ,Schaufelkanäle beider Fluten des Laufrades 1 durchströmen. Soll der Volumenstrom geändert werden, wird die verschiebbare Diffusorwand 14 in Richtung zur feststehenden Wand 13 verstellt und anschließend oder gleichzeitig die öffnung der Blende 11 dementsprechend verringert. When the aperture II is fully open and the displaceable diffuser wall 14 is in the Lp ^ e shown with full lines, the working fluid can flow through the entire cross section of the blade channels of both flows of the impeller 1. If the volume flow is to be changed, the displaceable diffuser wall 14 is adjusted in the direction of the stationary wall 13 and then or at the same time the opening of the diaphragm 11 is correspondingly reduced.
Dadurch kann die äußere Flut des Laufrades 1 teilweise oder gänzlich abgesperrt werden. Bei völliger Abdeckung der äußeren Flut an der Eintrittsseite des Laufrades 1 und bei gleichzeitiger entsprechender Verstellung der Diffusorwand 14 am Laufradaustritt 12 fördert das Laufrad nur die Menge, die durch die innere Flut strömt, und zwar mit einem Wirkungsgrad, der etwa der spezifischen Drehzahl des inneren Teilrades entspricht. Bei weiterer Verstellung der Blende 11 und der verschiebbaren Diffusorwand 14 kann der EinlaufquerschniH der inneren Flut und dadurch der die Verdichterstufe durchströmende Volumenstrom weiter verringert werden. As a result, the outer tide of the impeller 1 can be partially or completely shut off. With complete coverage of the outer tide on the inlet side of the impeller 1 and at the same time corresponding adjustment of the diffuser wall 14 at the impeller outlet 12, the impeller only promotes the amount that flows through the inner tide, with an efficiency that is approximately the specific speed of the inner Part of the wheel corresponds. With further adjustment of the diaphragm 11 and the displaceable diffuser wall 14, the inlet cross-section of the inner flow and thereby the volume flow flowing through the compressor stage can be further reduced.
Für die Merkmale de- Unteransprüche wird Schutz nur in Verbindung mit den Merkmalen des Anspruchs 1 beansprucht.For the features of the subclaims, protection is only available in conjunction with the features of claim 1 claimed.
