Abstract
Die Erfindung betrifft eine Pumpe in Francis-Bauart, umfassend die folgenden Merkmale: – ein Laufrad; – ein Spiralgehäuse; – ein Saugrohr; – einen im Zulauf zum Laufrad angeordneten Gegendrallerzeuger, der während des Anfahrens der Pumpe aktivierbar, und nach dem Anfahren deaktivierbar ist, und der einen entgegen der Drehrichtung des Laufrades wirkenden Drall erzeugt.The invention relates to a Francis type pump comprising the following features: an impeller; - a volute casing; - a suction pipe; - A counter-swirl generator arranged in the inlet to the impeller, which can be activated during start-up of the pump and deactivated after start-up, and which generates a swirl that acts against the direction of rotation of the impeller.
Description
Die Erfindung betrifft eine Pumpe in Francis-Bauweise für ein Wasserkraftwerk zum Pumpen von Wasser von einem Unterwasserbecken zu einem Oberwasserbecken.The invention relates to a pump in Francis design for a hydroelectric power plant for pumping water from an underwater pool to an upper water basin.
Eine solche Pumpe weist ein Laufrad auf, ein Spiralgehäuse sowie ein Saugrohr.Such a pump has an impeller, a volute and a suction tube.
Sie kann Bestandteil eines Pumpspeicherwerkes sein. Als solche kann sie bei Strömung des Wassers vom Oberwasserbecken zum Unterwasserbecken als Turbine betrieben werden. Siehe
Eine solche Pumpe ist auf gewisse, kraftwerkbedingte Parameter ausgelegt, vor allem auf eine gewisse Förderhöhe und einen gewissen Durchsatz.Such a pump is designed for certain, power plant-related parameters, especially on a certain head and a certain throughput.
Bei solchen Pumpen kommt es immer wieder zu Problemen beim Anfahren. Die Probleme liegen darin, dass es beim Anfahren gar nicht zum Fördern von Wasser kommt, weil die Strömung instabil ist.With such pumps, there are always problems when starting up. The problems are that it does not come to the delivery of water when starting, because the flow is unstable.
Die Erfinder haben folgendes erkannt:
Die Probleme treten dann auf, wenn die Förderhöhe über ein bei der Konstruktion zugrunde gelegtes Maß hinausgeht. Dies kann zum Beispiel dann eintreten, wenn der Oberwasserspiegel besonders hoch ist, oder wenn der Unterwasserspiegel besonders niedrig ist, oder wenn beides gleichzeitig eintritt. Sie haben somit die Förderhöhe als besonders kritische Größe erkannt.The inventors have recognized the following:
The problems occur when the head goes beyond a design basis. This can happen, for example, when the surface water level is particularly high, or when the underwater level is particularly low, or when both occur simultaneously. They have thus recognized the head as a particularly critical size.
Der Erfindung liegt die Aufgabe zugrunde, eine Pumpe der eingangs genannten Art derart zu gestalten, dass die Strömung auch bei großen Förderhöhen stabil ist und das Anfahren der Pumpe ermöglicht.The invention has for its object to design a pump of the type mentioned in such a way that the flow is stable even at high heights and allows the start of the pump.
Die Lösung besteht in Folgendem:
- – Im Zulauf zur Pumpe werden Drallerzeuger vorgesehen
- – Insbesondere werden dem Saugrohr eine Anzahl von Leitelementen zugeordnet, die am Umfang des Saugrohres angeordnet sind und die während des Anfahrens der Pumpe in die vom Saugrohr geführte Strömung einrückbar sind.
- – Die Leitelemente sind derart gestaltet und angeordnet, dass sie der Strömung einen zur Umdrehung des Laufrades entgegengesetzten Drall verleihen. Damit lässt sich die Strömung beim Anfahren stabilisieren.
- - In the inlet to the pump swirl generators are provided
- - In particular, the intake manifold a number of guide elements are assigned, which are arranged on the circumference of the suction tube and which are engageable during start-up of the pump in the flow guided by the suction pipe.
- - The vanes are designed and arranged so that they impart the flow opposite to the rotation of the impeller twist. This allows the flow to stabilize when starting.
Ist beim Anfahren durch den Gegendrall erst einmal eine stabile Strömung hergestellt, so können die Leitelemente wieder ausgerückt werden.Once a stable flow is established during startup by the counter-rotation, the guide elements can be disengaged again.
Die Erfindung sowie der Stand der Technik sind anhand der Zeichnung näher erläutert. Darin ist im Einzelnen folgendes dargestellt:The invention and the prior art are explained in more detail with reference to the drawing. The following is shown in detail:

Es ist auch denkbar, das Leitelement
Der Gegendrallerzeuger kann auch eine andere Gestalt aufweisen, als der dargestellte. So kann das Leitelement auch als drehbares Element ausgebildet sein, umfassend eine Drehachse und eine Mehrzahl von auf der Drehachse sitzenden Schaufeln. Auch kann eine nicht-mechanische Lösung in Betracht kommen. So können beispielsweise Düsen vorgesehen werden, mit denen das Saugrohr bestückt ist, beispielsweise in seinem Auslassabschnitt
Die Erfindung lässt sich auch bei Pumpturbinen anwenden. In einem solchen Falle werden die Gegendrallerzeuger im Pumpbetrieb aktiviert – wiederum nur beim Anfahren.The invention can also be applied to pump turbines. In such a case, the counter-swirl generators are activated in pumping mode - again only when starting up.
