Description
Einrichtung zur Förderung von Gasen oder Flüssigkeiten mit einem Schraubenrad im Einlaufkanal eines Fliehkraftrades und zwischen Schrauben- und Fliehkraftrad eingeschaltetem, von innen nach außen durchströmtem Di$usor Die Erfindung betrifft eine Einrichtung zur Förderung von Gasen oder Flüssigkeiten mit einem Schraubenrad im Einlaufkanal eines Fliehkraftrades und mit zwischen Schrauben- und Fliehkraftrad eingeschaltetem, von innen nach außen durchströmtem Diffusor. Die Erfindung besteht darin, daß der Diffusor mit keinem der beiden Umlaufräder verbunden, sondern selbst drehbar und besonders angetrieben ist, so daß er mit von Fliehkraft- und Schraubenrad abweichender Drehzahl laufen kann. Während bei den bisherigen Ausführungen der Diffusor zu einem der beiden Räder, also entweder zu dem Fliehkraft- oder zu dem Schraubenrad, gehörte und mit der entsprechenden Drehzahl umgelaufen ist, wird ihm nunmehr eine von beiden Rädern unabhängige Drehzahl erteilt. Hieraus ergibt sich der betriebstechnische Vorteil, daß der Diffusor, der früher nur als Leitapparat gedient hat, seine Eigenschaften mit der eines Fliehkraftrades verbindet. Obwohl in seinem Innern keine Schaufeln angeordnet sind, so arbeitet er infolge der ihm erteilten Drehung durch den besonderen Antrieb wie eine Zentrifuge. Die Größe der Zentrifugalwirkung hängt von der Drehzahl des Diffusors ab. Die Einrichtung zur Förderung von Gasen oder Flüssigkeiten gemäß der Erfindung hat daher einen besseren Ausnutzungsfaktor als die bekannten Einrichtungen.Device for conveying gases or liquids with a helical wheel in the inlet channel of a centrifugal bike and between the helical and centrifugal bike switched on, flowed through from the inside to the outside Di $ usor The invention relates a device for conveying gases or liquids with a helical gear in the inlet channel of a centrifugal bike and with between the helical and centrifugal bike switched on, diffuser with flow from inside to outside. The invention exists in the fact that the diffuser is not connected to either of the two rotating gears, but to itself is rotatable and specially driven, so that it is with the centrifugal and helical gear different speed can run. While in the previous versions the diffuser to one of the two wheels, i.e. either to the centrifugal or to the helical gear, belonged to and ran at the appropriate speed, it will now be a independent speed given by both wheels. This results in the operational Advantage that the diffuser, which previously only served as a diffuser, retains its properties connects with that of a centrifugal bike. Although there are no shovels inside are arranged, he works as a result of the rotation given to him by the special Drive like a centrifuge. The size of the centrifugal effect depends on the speed of the diffuser. The device for conveying gases or liquids according to the invention therefore has a better utilization factor than the known devices.
In der Figur ist ein Ausführungsbeispiel der Erfindung dargestellt, an das die Erfindung in ihren Einzelheiten aber nicht gebunden sein soll. Die dargestellte Zeichnung soll vielmehr nur eine von vielen Ausführungsmöglichkeiten zeigen.In the figure, an embodiment of the invention is shown, to which the invention is not intended to be bound in its details. The one shown Rather, the drawing should only show one of many possible designs.
Die Welle i trägt ein Schraubenrad 2. Gleichachsig mit der Welle i ist die Welle 3 angeordnet, die den Diffusor ¢ und das Fliehkraftrad 5 trägt. Der Diffusor q. ist mit Hilfe des Keiles 6 auf der Welle unmittelbar befestigt, während das Fliehkraftrad 5 mit Hilfe der Buchse 7 drehbar auf der Welle 3 gelagert ist. Die Welle i wird über die Riemenscheibe 8, die Welle 3 über die Riemenscheibe 9 und die Buchse 7 über die Riemenscheibe io angetrieben. Die Antriebe können regelbar sein, so daß alle drei Teile mit beliebig voneinander verschiedenen oder auch mit gleichen Drehzahlen laufen können. Zum Antrieb dienen an sich bekannte Einrichtungen, z. B. Elektromotoren.The shaft i carries a helical gear 2. Coaxial with the shaft i the shaft 3 is arranged, which carries the diffuser [and the centrifugal wheel 5]. Of the Diffuser q. is attached directly to the shaft with the help of the wedge 6, while the centrifugal motorcycle 5 is rotatably mounted on the shaft 3 with the aid of the bushing 7. The shaft i is via the belt pulley 8, the shaft 3 via the belt pulley 9 and the bush 7 is driven via the pulley io. The drives can be regulated so that all three parts with arbitrarily different from each other or with can run at the same speeds. Devices known per se are used for the drive, z. B. electric motors.
