Description

Schaufelradpumpe mit tangentialem Wasser-Ein-_ und -Austritt Die Erfindung bezieht sich auf eine Verbesserung an Schaufelradpumpen mit tangelntialer Ein- und Ausströmung der Förderflüssigkeit. Bei diesen wird die FördeTflüssigkeit von den Schaufeln des Laufrades von der Saug- zur Druckseite durch einen Kanal hindurchgezogen oder -getrieben, der so weit ist, daß die Schaufeln mit viel Spielraum hindurchgehen. Abgesehen von einem gewissen Schlupf entspricht die durchgetriebene Flüssigkeitsmenge der Kanahveite. Bei ihrem Übergang von der Druck- zur Saugseite gehen die Schaufeln durch ein engschliaeßendes Kanalstück hindurch. Dabei sind die Zwischenräume zwischen den Schaufeln mit Förderflüssigkeit gefüllt, und es wird eine dementsprechende Menge Flüssigkeit von der Druckzur Saugseite zurückgefördert. Die Differenz zwischen der von der Saug- zur Druckseite und der von der Druck- zur Saugseite geförderten Menge wird wirklich von der Pumpe gefördert. Die vorliegende Erfindung bezweckt, derartige Pumpen selbstansaugend bzw. luftfördernd zu machen. Zur Erzielung eines Luftförderungsvermögens arbeitet die Pumpe beim Ansaugen mit einem Rest von Wasser, der in der Pumpe dadurch zurückbleibt, daß gemäß Abb. i sowohl der Eintrittskanal 5 als auch der Austrittskana18 von oben tangential an das Laufrad herangeführt wird. Solange die Pumpe ansaugt, also nur Luft fördert, wird vom Laufrad annähernd so viel Wasser im Kreise herumgeschleudert, als die Zwischenräume zwischen den Schaufehl i im übergangskanal3 zu fassen vermögen. Dieses im Kreisse herumgeschleuderte Wasser tritt mit den Schaufeln i zusammen als Strahl aus dem übergangskana13 heraus, der gemäß. der Erfindung an dieser Stelle 2 durch einen die Schaufeln überdekkenden Ansatz 6 verlängert ist, so daß, er düsenartig in den Saugkanal 5 und den dort beginnenden erweiterten Schaufelkanal 4. hineinragt. Der Wasserstrahl wird dadurch an dieser Stelle zusammengehalten und besser in den Kanal ¢ übergeleitet. Der mit großer Geschwindigkeit in den Kanal 4 eintretende Wasserstrahl, der gewissermaßen mit den Schaufehl i durchsetzt ist, reißt die aus dem Saugkana15 hinzutretende Luft mit in den Kanal 4. hinein, mischt sich mit dieser Luft und führt sie mit zum Druckkanal 8-. Hier steigt ein großer Teil der Luft in die Höhe, und .es bleibt Wasser, mit :einer geringeren Luftmenge vermischt, zwischen den Schaufeln, wenn diese in den übergangskanal3 eintreten.Impeller pump with tangential water inlet and outlet The invention refers to an improvement on impeller pumps with tangential inlet and outlet Outflow of the pumped liquid. With these, the delivery liquid is from the The blades of the impeller pulled through a channel from the suction to the pressure side or driven that is so wide that the blades go through with a lot of clearance. Apart from a certain amount of slip, the amount of liquid driven through corresponds to the Kanahveite. The blades move when they transition from the pressure side to the suction side through a narrow piece of duct. Here are the spaces between the paddles are filled with the pumping liquid, and a corresponding amount is generated Liquid returned from the pressure side to the suction side. The difference between the from the suction to the pressure side and the amount conveyed from the pressure to the suction side is really delivered by the pump. The present invention aims to achieve such To make pumps self-priming or air-conveying. To achieve air pumping capacity the pump works when it is primed with a remainder of the water that is in the pump what remains is that, according to Fig. i, both the inlet channel 5 and the outlet channel18 is brought up to the impeller tangentially from above. As long as the pump is sucking, i.e. only transports air, almost as much water is thrown around in a circle by the impeller, than the gaps between the blades i in the transition channel3 are able to grasp. This water thrown around in a circle comes together with the blades i as Ray out of the transition channel, which according to. of the invention at this point 2 is extended by a projection 6 covering the blades, so that it is like a nozzle protrudes into the suction channel 5 and the enlarged blade channel 4 beginning there. The water jet is held together at this point and better in the Channel ¢ transferred. The one entering channel 4 at great speed The water jet, which is, so to speak, interspersed with the shovel i, rips them out The air entering the suction channel 15 with the channel 4, mixes with it Air and leads it to the pressure channel 8-. A large part of the air rises in here the altitude, and. it remains water, mixed with: a smaller amount of air, between the blades when they enter the transition channel3.
