Description
<Desc/Clms Page number 1>
Regelbare Kreiselpumpe
EMI1.1
<Desc/Clms Page number 2>
EMI2.1
DrehzahlKränze gegeneinander kann auf einen bestimmten Wert festgelegt sein oder aber auch veränderlich gemacht werden, etwa dadurch, dass die Nabe 4 längs des einen oder beider gestrichelt eingezeichnoter Kreise in zwei bzw. drei Ringe unterteilt wird, die mittels einer Verstellvorrichtung um einen bestimmten Betrag in Umfangsrichtung relativ gegeneinander verdrehbar sind. Für die verdreh-bzw. verschwenkbare Anordnung der Schaufeln der Kränze 20 und 22 sind im Abschnitt c einige von meh-. reren Möglichkeiten angegeben. Für sämtliche Schaufeln ein und desselben Kranzes muss selbstverständlich stets die gleiche Anordnung ausgeführt werden, um die Rotationssymmetrie der Strömung zu gewährleisten.
Dies gilt auch in bezug auf eine etwa vorgesehene Verschiebung der beweglichen Schaufeln senkrecht zu ihrer Dreh- bzw. Schwenkachse 23.
<Desc/Clms Page number 3>
In den Abschnitten b und d sind wieder in schematischer Darstellung Laufräder mit vier aufeinander- folgenden Schaufelkränzen 20, 21a, 21b und 22, von denen im Abschnitt b beispielsweise der Schaufel- kranz 21b mit doppelter Schaufelzahl ausgeführt ist, angedeutet. Für diese Laufräder gilt das zu den
Laufrädern mit nur drei Schaufelkränzen gesagte sinngemäss. In beiden Fällen sind die dargestellte An- zahl und Form der Schaufeln sowie deren Profillänge nur als Beispiel anzusehen, sie können den Erforder- nissen entsprechend auch anders ausgeführt werden.
PATENTANSPRÜCHE :
1. Halbaxial oder radial durchströmte, regelbare Kreiselpumpe oder Pumpenturbine, dadurch ge- kennzeichnet, dass das Laufrad drei oder vier in Strömungsrichtung aufeinanderfolgende unabhängige Krän- ze (9, 5, 7 bzw. 20, 21, 22 bzw. 20, 2la, 2lb, 22) von selbständigen Laufschaufeln aufweist und dass die
Schaufeln des ersten und des letzten Kranzes (9 und 7 ; 20 und 22) verdrehbar oder verschwenkbar ausgebildet sind.

EMI2.1
Speed rings against each other can be set to a certain value or can also be made variable, for example by dividing the hub 4 along one or both circles drawn in dashed lines into two or three rings, which by means of an adjusting device by a certain amount in the circumferential direction are rotatable relative to each other. For the twisting or. pivotable arrangement of the blades of the rings 20 and 22 are some of several in section c. other possibilities indicated. It goes without saying that the same arrangement must always be carried out for all the blades of one and the same ring in order to ensure the rotational symmetry of the flow.
This also applies with regard to an approximately intended displacement of the movable blades perpendicular to their axis of rotation or pivot axis 23.
<Desc / Clms Page number 3>
In sections b and d, impellers with four successive blade rings 20, 21a, 21b and 22, of which, for example, blade ring 21b is designed with twice the number of blades in section b, are again indicated in a schematic representation. The same applies to these wheels
Impellers with only three blade rings said accordingly. In both cases, the number and shape of the blades shown, as well as their profile length, are only to be regarded as an example; they can also be designed differently according to requirements.
PATENT CLAIMS:
1. A controllable centrifugal pump or pump turbine with a semi-axial or radial flow, characterized in that the impeller has three or four independent rings (9, 5, 7 or 20, 21, 22 or 20, 2la, 2lb , 22) of independent rotor blades and that the
The blades of the first and last ring (9 and 7; 20 and 22) are designed to be rotatable or pivotable.
