Description

Schaufelradpumpe Die Erfindung betrifft eine weitere Verbesserung des Luftfördervermögens der Schaufelradpumpen gemäß Patent q.99 484. Das Luftförderungsvermögen wird um so größer, je besser und reichlicher die Mischung der Luft mit dem in der Pumpe kreisenden Wasser beim Ansaugen erfolgt. .Impeller Pump The invention relates to a further improvement the air pumping capacity of the impeller pumps according to patent q.99 484. The air pumping capacity becomes all the greater, the better and more abundantly the mixture of the air with that in the Pump circulating water when sucking takes place. .

In den Abb. i und s ist die weitere Verbesserung der Schaufelradpumpe schematisch dargestellt. Abb. i zeigt einen Schnitt durch die Pumpe mitten durch das Schaufelrad i. Abb. a einen Schnitt, der in Abb. i durch die krumme Linie A-A angedeutet ist. Ein besseres Ansaugen und eine bessere Vermischung der Luft mit dem Wasserstrahl wird dadurch erreicht, daß die Düse 6, welche in den Saugkanal hineinreicht, mit Löchern 9 versehen ist, und daß sich diese Düse entsprechend der Luftaufnahme des vom Schaufelrad durch den Übergangskanal 3 von der Druckseite Q, zur Saugseite getriebenen Wasserstrahls erweitert. Infolge dieser Erweiterung io erzeugt der schnell durch die Düse 6 hindurchtretende Strahl eine Saugwirkung in derselben, und es treten durch die vielen. kleinen Löcher 9 Luftstrahlen von den Seiten in die Düse 6 ein, die sich sofort mit dem Wasserstrahl innig mischen und durch den Schaufelkanal 4 weiterbefördert werden.In Fig. I and s is the further improvement of the paddle wheel pump shown schematically. Fig. I shows a section through the pump through the middle the paddle wheel i. Fig. A is a section that is shown in Fig. I through the curved line A-A is indicated. A better suction and a better mixing of the air with the water jet is achieved in that the nozzle 6, which in the suction channel extends in, is provided with holes 9, and that this nozzle according to the Aerial view of the paddle wheel through the transition channel 3 from the pressure side Q, extended to the suction side driven water jet. As a result of this expansion io the jet rapidly passing through the nozzle 6 generates a suction effect in same, and step through the many. small holes 9 air jets from the Pages into the nozzle 6, which immediately mix intimately with the water jet and be conveyed further through the blade channel 4.
