Description

Vorrichtung zum Fördern von Flüssigkeiten, Luft oder Gasen mittels Schleudergebläse. Bei der Vorrichtung gemäß dem Patent 368300 erhält der Diffusor eine zu dem Schleuderradläufer gegenläufige Bewegung durch die beim Fördern des Mittels entstehende Rückwirkung. Es ist aber damit zu rechnen, daß namentlich bei Vorrichtungen für hohe Leistungen, unter andern- beispielsweise. mehrstufigen Kompressoren, die Geschwindigkeit des Diffusors, die sich aus der vorerwähnten Rückwirkung allein ergibt, nicht derjenigen gleich ist, die dem günstigsten Wirkungsgrade entspräche. Lediglich um die Annäherung zu dem letzteren noch mehr zu vervollkommnen, soll erfindungsgemäß der Diffusor in seiner Geschwindigkeit durch eine zusätzliche Hilfskraft beeinflußt werden, wobei als leitender Gedanke die Erkenntnis ist, daß erhebliche Kräfte zur Einstellung der günstigsten Drehgeschwindigkeit nicht aufgewendet zu werden brauchen.Device for conveying liquids, air or gases by means of a centrifugal fan. In the device according to patent 368300 , the diffuser receives a movement in the opposite direction to that of the centrifugal impeller due to the reaction produced when the agent is conveyed. It is to be expected, however, that especially in the case of devices for high outputs, among other things, for example. multi-stage compressors, the speed of the diffuser, which results from the aforementioned reaction alone, is not the same as that which would correspond to the most favorable efficiency. According to the invention, the speed of the diffuser is to be influenced by an additional auxiliary force, the guiding idea being the knowledge that considerable forces do not need to be used to set the most favorable rotational speed.

Die Zeichnung zeigt in Abb. i und 2 im Ouerschnitt und Längsschnitt die Vorrichtung schematisch.The drawing shows in Fig. I and 2 in cross section and longitudinal section the device schematically.

Wie im Hauptpatent 368300 -ist c, die Welle des Radläufers b, die im Ständer d gelagert und etwa durch eine Riemenscheibe e angetrieben wird. c ist der durch die Rückwirkung in gegenläufige Bewegung versetzte Diffusor. Seine Nabe f läuft auf Kugeln, die- zwischen dieser und der Außenfläche des Lagers der Welle a eingebettet sind. Um nun dem Diffusor c eine zusätzliche Kraft zu erteilen, die ihn zu einer etwas höheren oder niedrigeren Drehgeschwindigkeit, als wie sie die Folge der Rückwirkung ist, zu veranlassen, ist beispielsweise auf die Nabe f eine schwache Rillenscheibe g gesetzt, die mit einem Seil besonders angetrieben wird. Die. Rillenscheibe und das Seil als Antriebselement sind natürlich nur als Beispiel gedacht. Insbesondere können auch mehrstufige Antriebsvorrichtungen für Geschwindigkeitsänderung in Frage kommen. Es ist klar, daß eine solche Hilfsvorrichtung von der schwächsten Bauart sein kann, da ihr Zweck nicht darin besteht, den Diffusor anzutreiben, sondern nur seine Drehgeschwindigkeit auf den Grad zu bringen, der der günstigsten Wirkung am nächsten kommt. Unter Umständen kann ihre Aufgabe sogar darin liegen, auf den Diffusor bremsend zu wirken.As in the main patent 368300 -is c, the shaft of the wheel runner b, which is mounted in the stator d and driven for example by a pulley e. c is the diffuser set in opposite motion by the reaction. Its hub f runs on balls which are embedded between this and the outer surface of the bearing of the shaft a. In order to give the diffuser c an additional force that causes it to rotate at a slightly higher or lower speed than is the result of the reaction, a weak pulley g is placed on the hub f, for example, with a rope in particular is driven. The. Pulley and the rope as a drive element are of course only intended as an example. In particular, multi-stage drive devices for changing the speed can also be considered. It is clear that such an auxiliary device can be of the weakest type, since its purpose is not to drive the diffuser, but only to bring its speed of rotation to the degree which comes closest to the most favorable effect. Under certain circumstances, their task can even be to act as a brake on the diffuser.
