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 can also be used in combination with other types of control, e.g. with the speed or swirl throttle control. As a result, you may still be able to better results can be achieved.
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 the essential part represents the arrangement according to the invention in axial section.
Das zweiflutige Laufradi besteht aus einer Radscheibe!, die Laufschaufeln3 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.The double-flow impeller consists of a wheel disc! carries the blades 3 of the first (inner) tide 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 plate 6.
Die beiden Laufschaufelsysteme 3 und 4 bilden somit zusammen mit der Radscheibe 2 und der Deckscheibe 5 bzw. 6 ein inneres Teilrad 7 und ein äußeres 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, respectively, an inner partial wheel 7 and an outer partial wheel 8.
Die Saugleifung9 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 pipe 9 of the double-flow impeller 1 is axially arranged. Just before the entry into the blade channels, the wall is perpendicular to the flow a diaphragm 11 with an adjustable opening is arranged, the center of which is in the impeller axis lies. At the impeller outlet 12 there is a ring diffuser with a fixed 13 and a movable wall 14 arranged.
Wenn die Blende 11 voll geöffnet ist und die verschiebbare Diffusorwand 14 in der mit voll ausgezogenen Linien dargestellten Lage 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 shutter 11 is fully open and the sliding Diffuser wall 14 is in the position shown with full lines, the working equipment 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 in the direction of the stationary one Wall 13 adjusted and then or at the same time the opening of the aperture 11 accordingly decreased.
Dadurch kann die äußere Flut des Laufrades 1 teilweise oder gänzlich abgesperrt werden. Bei völliger Abdeckung der äußeren Flut an der Eintnttsseite 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 Einlaufquerschnitt 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 Covering the outer tide on the Eintnttsseite 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 is passed through the inner tide flows, and with an efficiency that approximately the specific speed of the inner Part of the wheel corresponds. With further adjustment of the screen 11 and the displaceable diffuser wall 14 can be the inlet cross-section of the inner flow and thereby the volume flow flowing through the compressor stage can be further reduced.
