Abstract

Det blir beskrevet en fremgangsmåte og et system for å dempe trykksvingningene i vannturbiner som drives under delvis belastning, ved å injisere én eller flere styrestråler av væske med høy hastighet nedstrøms for turbinløpehjulet, på det øvre parti av sugerøret, langs maskinaksen; hvor strømningshastigheten til væskestrålen eller -strålene kan justeres kontinuerlig avhengig av trykksvingningsnivået i sugerøret for å regulere virvelstrømningen nedstrøms for løpehjulet og unngå spiralformet virvelnedbryting ved delvis belastning for derved å eliminere hovedårsaken til trykksvingninger.
