Füllen
Die Bilder 8 und 9 zeigen Aufzeichnungen der Füllvorgänge in der Anlage für Pumpen- und Turbinendrehrichtung.
Beide Vorgänge sind steuerungstechnisch gleich und laufen wie folgt ab:
1.
Öffnen des Dichtrings am Kugelschieber, schließen Spiralentlastung und Spaltentlastung, öffnen Spiralentlüftung.
Der Druck in der Spirale steigt wie beim Modellversuch schnell auf Rohrbahndruck an.
2.
Kugelschieber beginnt zu öffnen.
Leistung und Druck zwischen Lauf- und Leitrad steigen während der ersten Füllphase ähnlich wie im Modell an.
3.
Aus Sicherheitsgründen werden die Laufradentlüftung und die Entlastung der Deckelentlastung erst nach Erreichen ***des Druckes*** zwischen Lauf- und Leitrad am Ende der ersten Füllphase geöffnet, die zweite Füllphase beginnt.

EN:
once the ***necessary*** pressure between the runner and the guide wheel is achieved?

start-up pressure


Explanation:
I think that I know exactly what it means, if it is referred to a turbine - I've seen it and heard it - it's a phase typically characterized by a whistle-like sound of the vent of a turbo-system. In the first filling phase, for the start-up acceleration a certain pressure builds up, which exceeds the rated pressure necessary to the ordinary functioning of the turbine. This excess of pressure is vented towards the end of the the start-up phase of the turbo-system in order to create the right amount of pressure for ordinary system running.
