German term or phrase: Anfahrförderhöhe
DE:
Entlüften
Das Entlüften erfolgt als zweite Phase des gesamten Füllvorgangs über Bohrungen im Laufradboden und die Entlüftungsleitung A (Bild 1).
In der ersten Phase wird nicht nur der beschaufelte Teil des Laufrades, sondern es werden auch die Radseitenräume mit Wasser gefüllt, d.h. der Druck pflanzt sich auch dort fort, vermindert um den Anteil der Rotation des Wassers.
Je höher nun der Druck im druckseitigen Radseitenraum ansteigt, desto schneller kann das Wasser von dort bis zur Entlüftungsleitung vordringen und dort die Entlüftung stark behindern oder unmöglich machen.
Dieser Effekt konnte bei den Modellversuchen beobachtet werden, er trat, wie in [5] berichtet wird, auch schon in Anlagen auf.
Wegen des höheren Laufraddruckes in Pumpendrehrichtung ist davon vorwiegend das Füllen für den Pumpenbetrieb betroffen.
In diesem Fall erreicht das Laufrad nicht die notwendige ***Anfahrförderhöhe***, deshalb ist der Übergang zum Pumpenbetrieb durch öffnen der Leitschaufeln nicht möglich.

Is this "conveying level at system start-up"?

Cheers,

start-up delivery head


Explanation:
This is about the minimum delivery head (the energy difference, can be in distance like meters, or potential energy, of the fluid between pump inlet and outlet) required for the pump to start.
