Description
Die Erfindung betrifft eine dleichdruckturbine für Preßluft in axialer Bauart mit drei Geschwindigkeitsstufen, die, obwohl im gemeinsamen Gehäuse vereint, im Gegensatz zur üblichen-Bauart "solcher Turbinen jede ihr eigenes, von den anderen unabhängiges Laufrad nebst Welle besitzen. Die Leitschaufeln zwischen, den Laufrädern sind dabei gerade, also lenken die Strömung nicht um und können daher sehr kurz sein; die Laufräder sind daher gegenläufig. Die Turbine gestattet, gleichzeitig drei Arbeitsmaschinen anzutreiben. Von der Turbine wird guter Wirkungsgrad, billiger Betrieb, Betriebssicherheit, Platzersparnis und besondere Eignung für kleine und mittlere Leistungen erwartet. _ Die Wirkungsweise dieser Turbine gleicht im Gründe derjenigen der üblichen Gleichdruckturbine mit Geschwindigkeitsstufen.The invention relates to a pressure turbine for compressed air in the axial direction Design with three speed levels, which, although combined in a common housing, In contrast to the usual design "of such turbines, each one of its own from the others Have an independent impeller and shaft. The guide vanes between, the impellers are straight, so do not divert the flow and can therefore be very short be; the impellers are therefore in opposite directions. The turbine allows simultaneously to drive three work machines. The turbine becomes more efficient and cheaper Operation, operational safety, space saving and special suitability for small and medium performance expected. _ The way this turbine works is basically the same that of the usual impulse turbine with speed levels.
Die Zeichnung zeigt in Abb. i eine erfindungsgemäße Turbine im Längsschnitt, in Abb. 2 einen Schnitt durch die Düsen und Schaufeln entlang dem Umfang (abgewickelt). Die Düsen i der Druckstufe, die Leitschaufeln 2 und 3 der Geschwindigkeitsstufen, die Laufschaufeln 4 bis 6 und der Austrittskanal 7 bilden den Preßluftweg. Die Zwischenböden ii und 12 und die Gehäusedeckel 13 und 14 bilden das Gehäuse. Die Laufräder 8 bis io sitzen auf den vollen Wellen 15 und 16 und der hohlen Welle 17. Die Welle 15 ruht in den Lagern 18 und i9, die Welle 16 in den Lagern 2o und 21, die Welle 17 in den Lagern 22 und 23. In den Lagern 24 und 25 ist die Welle 16 in der Welle 17 geführt. Mindestens die Lager 24 und 25 sind Rollen-oder Nadellager. Die Leitschaufelkränze, die bei üblichen Gleichdruckturbinen mit Geschwindigkeitsstufen gebräuchlich sind, sind hier also durch Zwischenböden ersetzt, und diese dienen zur Lagerung der Wellen. Die Dichtungsringe 26 fangen den Preßluftstrahl in die Schaufeln ein und sollen so Undichtigkeiten und Randwirbel an den Schaufelenden vermeiden.The drawing shows in Fig. I a turbine according to the invention in longitudinal section, in Fig. 2 a section through the nozzles and blades along the circumference (developed). The nozzles i of the pressure stage, the guide vanes 2 and 3 of the speed stages, the blades 4 to 6 and the outlet channel 7 form the compressed air path. The intermediate floors ii and 12 and the housing cover 13 and 14 form the housing. The wheels 8 to io sit on the full shafts 15 and 16 and the hollow shaft 17. The shaft 15 rests in bearings 18 and 19, shaft 16 in bearings 2o and 21, shaft 17 in bearings 22 and 23. In bearings 24 and 25, shaft 16 is in shaft 17 guided. At least the bearings 24 and 25 are roller bearings or needle bearings. The guide vane rings, which are used in conventional impulse turbines with speed levels, are replaced here by intermediate floors, and these are used to support the shafts. The sealing rings 26 capture the compressed air jet in the blades and are intended in this way, avoid leaks and edge eddies at the blade ends.
