Description
Vorrichtung zur wahlweisen Parallel- und Hintereinanderschaltung von Kreiselverdichtern bzw. -gebläsen Es ist bei Pumpen und Verdichtern bekannt, einzelne Räder oder Radgruppen parallel oder hintereinanderzuschalten. Meist sind die Umschaltorgane, wie Schieber, Rückschlagklappen o. dgl., in den Saug-, Druck-und Verbindungsleitungen der einzelnen Räder bzw. Radgruppen angeordnet, oder sie sind auch zum Teil unmittelbar in das. Gehäuse eingebaut, wobei besondere Umschaltkanäle vorgesehen sind.Device for the optional parallel and series connection of Centrifugal compressors or fans It is known for pumps and compressors, individual To switch wheels or wheel groups in parallel or one behind the other. Most of the time the switching organs are such as slides, non-return valves or the like, in the suction, pressure and connecting lines of the individual wheels or groups of wheels, or some of them are also direct Built into the housing, with special switching channels being provided.
Den Gegenstand der Erfindung bildet .eine besonders einfache Lösung zur beliebigen Parallel- oder Hintereinanderschaltung von Rädern bzw. Radgruppen eines zwei- oder mehrstufigen Kreiselverdichters bzw. -gebläses. Hiernach ist auf die bekannte Bauart von Kreiselverdichtern mit dicht nebeneinanderliegenden Rädern, deren Eintrittsöffnungen ich kreisringförmig überlagern, zurückgegriffen. Diese Bauart bezweckte bisher entweder die Verminderung der Radreibung oder mittels axial verschiebbaren Absperrorgans die zeitweise Absperrung eines der beiden Laufräder. Gemäß der Erfindung wird nun ein solches Absperrorgan derart als Umschaltorgan ausgebildet, daß bei dicht nebeneinanderliegenden Laufrädern mit sich kreisförmig überlagernden Eintrittsöffnungen die Laufräder wahlweise parallel oder hi.ntereinandergeschaltet werden können.The subject of the invention is a particularly simple solution for any parallel or series connection of wheels or groups of wheels a two- or multi-stage centrifugal compressor or fan. After that is on the well-known design of centrifugal compressors with closely spaced wheels, whose inlet openings I superimpose in a circular ring, drawn back. These Up to now, the aim of the design was either to reduce wheel friction or to use it axially sliding shut-off device temporarily shutting off one of the two impellers. According to the invention, such a shut-off device is now designed as a switching device, that when impellers are located close to one another with overlapping circular shapes Inlet openings the impellers can be connected in parallel or one behind the other can be.
In den Abb. i und 2 der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung in Parallel- bzw. Hintereinanderschaltung der Laufräder veranschaulicht. Die beiden Räder i und 2, welche fliegend oder zwischen zwei Lagern angeordnet sein können, sind in bekannter Weise seitlich nebeneinandergelegt mit auf der gleichen Seite beginnenden, sich kreisringförmig überlagernden Eintrittsöffnungen. Der Druckraum 3 des einen Rades ist in bekannter Weise um die eigentliche Druckspirale ¢ herumgeführt, so daß sämtliche Luftwege, welche bei der Umschaltung gesteuert werden müssen, örtlich nahe beisammen und auf einem möglichst kleinen Durchmesser liegen, was ein einfaches Umschaltorgan 5 ergibt, das alle Funktionen des Umschaltens gleichzeitig erfüllt. Abb. i zeigt die Vorrichtung in der Stellung für parallel geschaltete und Abb. 2 für hinter-Pinandergeschaltete Räder. 6 ist der Saugstutzen und 7 der Druckstutzen des Verdichters bzw. Gebläses. Das Umstellorgan kann beispielsweise mit Antrieb 8 verstellt werden. An Stelle einer axialen Verstellung des Organs 5 könnte auch eine Verdrehung in Frage kommen.In Figs. I and 2 of the drawing there is an exemplary embodiment the invention illustrated in parallel or series connection of the wheels. The two wheels i and 2, which are cantilevered or arranged between two bearings can, are placed side by side in a known manner with on the same Side beginning, circular overlapping inlet openings. The printing room 3 of one wheel is guided around the actual pressure spiral ¢ in a known manner, so that all airways that have to be controlled during the switchover are local close together and on the smallest possible diameter, which is a simple one Switching element 5 results, which fulfills all the functions of switching at the same time. Fig. I shows the device in the position for connected in parallel and Fig. 2 for rear-mounted wheels. 6 is the suction port and 7 is the pressure port of the compressor or fan. The changeover element can, for example, have a drive 8 can be adjusted. Instead of an axial adjustment of the organ 5 could also a twist come into question.
