Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung bezweckt, bei Ventilatoren oder Zentrifugalpumpen, welche mit konstanter Umdrehungszahl arbeiten müssen, die Leistung während des Ganges zu verändern. Dieses wird dadurch erreicht, daß man den Einlaufquerschnitt der Schaufeln des Flügelrades verändert, während der Auslaufquerschnitt der Schaufeln konstant bleibt. In der beiliegenden Zeichnung ist eineThe present invention aims at fans or centrifugal pumps, which with have to work at a constant speed to change the power during the course. This is achieved by changing the inlet cross-section of the blades of the impeller, while the outlet cross-section of the blades remains constant. In the accompanying drawing is a

ίο passende Ausführungsform nach Fig. ι für einen Grubenventilator gezeichnet. Und zwar bedeutet α das Flügelrad, welches durch den Elektromotor b in konstante Umdrehung versetzt wird. Die Luftführungswand c ist verschiebbar angeordnet, und zwar durch die Verschiebbarkeit ihrer Welle d, welche durch die hohle Hauptwelle e des Ventilators geht. Die Verschiebung der Welle d nebst der Luftführungswand c geschieht durch das am äußeren Ende verschiebbar angeordnete Kammlager /.ίο suitable embodiment according to Fig. ι drawn for a pit fan. In fact, α means the impeller, which is set in constant rotation by the electric motor b. The air guide wall c is arranged to be displaceable, through the displaceability of its shaft d, which goes through the hollow main shaft e of the fan. The displacement of the shaft d and the air guiding wall c takes place through the comb bearing / which is arranged displaceably at the outer end.

Fig. 2 läßt eine Schaufelform erkennen, und zwar bleibt die absolute Lufteintrittsgeschwindigkeit w J konstant, während die absolute Austrittsgeschwindigkeit tv"1 je nach der Förderleistung variabel wird, so daß der manometrische Wirkungsgrad ebenfalls variablen Wert hat. Der mechanische Wirkungsgrad wird durch die Einrichtung nicht beeinflußt.2 shows a blade shape, namely the absolute air inlet speed w J remains constant, while the absolute outlet speed tv " 1 is variable depending on the conveying capacity, so that the manometric efficiency also has a variable value. The mechanical efficiency is not reduced by the device influenced.
