Description

Es ist bannt, bei mehrstufigen Fliehkraftgebläsen das Fördermittel zwischen den einzelnen Stufen zu kühlen, um an Kompressionsarbeit zu sparen. Bei den bekannten Ausführungen werden die Kühler nach ein oder mehreren Stufen seitlich, oberhalb oder unterhalb des Gebläsegehäuses zugeordnet; es führt dies zu unschönen Bauarten, welche in der Regel - verhältnismäßig großen Raum beanspruchen.It is forbidden, with multi-stage centrifugal blowers, the funding to cool between the individual stages in order to save compression work. at the known designs the cooler after one or more stages laterally, assigned above or below the fan housing; it leads to unsightly Types, which as a rule - take up a relatively large amount of space.

Bei mehrstufiger Ausführung und bei Zwischenkühlung des Fördermittels und bei Vorhandensein von mindestens drei Teilspiralen beseitigt die vorliegende Erfindung obige Nachteile dadurch, daß die Kühler in die Überströmleitungen eingebaut werden.With multi-stage design and with intermediate cooling of the conveying means and in the presence of at least three partial spirals eliminates the present one Invention the above disadvantages in that the cooler is built into the overflow lines will.

Die Fig. i und a zeigen schematisch Beispiele von bisher üblichen Kühleranordnungen. In Fig. i sind die Kühlerz und 3 seitlich schief am Gebläsegehäuse i befestigt; in Fig. a sind die Kühler oben und unten angeordnet. Es entstehen so unschöne, großen Raum beanspruchende Bauarten.FIGS. I and a show schematically examples of previously common ones Cooler arrangements. In Fig. I, the cooler ore 3 and 3 are laterally oblique on the fan housing i attached; in Fig. a, the coolers are arranged above and below. It is created like this unsightly, large space-consuming constructions.

Die Fig.3 und 4 zeigen Ausführungsbeispiele des Erfindungsgegenstandes mit drei und mehr Teilspiralen. Die Kühler werden, weil pro Stufe in drei und mehr Teile unterteilt, kleiner in den Abmessungen, und zwar um so kleiner, je mehr Teilspiralen vorhanden sind. Die kleinen Kühler lassen sich in den Überströmleitungen besser unterbringen, und der Raumbedarf wird kleiner. Die Kühler können durch eine symmetrische Verschalung leicht umschlossen werden, so daß das ganze Gebläse nach außen ein gefälliges, z. B. zylindrisches Aussehen erhält.FIGS. 3 and 4 show exemplary embodiments of the subject matter of the invention with three or more partial spirals. The coolers are because there are three and more per stage Parts divided, smaller in size, the smaller the more spiral sections available. The small coolers can be better placed in the overflow lines and the space requirement becomes smaller. The cooler can be made by a symmetrical Casing are easily enclosed, so that the whole fan has a pleasing, z. B. obtained cylindrical appearance.

In Fig. 3 sind die Kühler z bis 4 in die Überströmdeitungen eines Drei-Diffusorengeb,läses eingebaut. Eine zyl.indTdsoüle 5 schließt das Gebläse nach außen ab.In Fig. 3, the cooler z to 4 are in the overflow lines one Three diffusers built, built-in. A zyl.indTdsoüle 5 closes the fan afterwards outside.

Die Fig.4 betrifft ein Beispiel mit vier Teilspiralen. An die Diffusoren I' bis IV' sind die Überströmleitungen I" bis IV" angeschlossen, in welche die Kühler I"' bis IV"' eingebaut sind. Je melh,r Teilspiralen, um so kleiner werden die Kühler, -die sich daher auch in axialer Richtung leichter unterbringen lassen, ohne die Abstände zwischen zwei Stufen allzusehr zu vergrößern. Die Kühlrohre können quer oder längs der Strömung oder sonst den Verhältnissen entsprechend angeordnet- werden.4 relates to an example with four partial spirals. The overflow lines I "to IV", in which the coolers I "'to IV"' are installed, are connected to the diffusers I 'to IV'. The more sub-spirals, the smaller the cooler - which can therefore also be accommodated more easily in the axial direction without increasing the distance between two stages too much. The cooling tubes can be arranged across or along the flow or otherwise according to the conditions.
