I en hydraulisk krets kan netto positiv sugehøyde (NPSH) referere til en av følgende parametere i analysen av kavitasjon: 1. Tilgjengelig NPSH (NPSHA): Et mål på hvor nær væsken på et gitt tidspunkt er å koke, og dermed også kavitere. 2. Påkrevd NPSH (NPSHR): Trykket på et spesifikt punkt (for eks. i pumpeinnløpet) som er nødvendig for å hindre kavitasjon. WebDer NPSH-Wert der Pumpe ergibt sich aus der Art der Konstruktion und der Pumpendreh-zahl. Je höher die Pumpendrehzahl wird, umso größer wird der NPSH-Wert der Pumpe. …

NPSH eller Net Positive Suction Head är ett mått på det minsta tryck vid inloppet som krävs för att kavitation i pumpen inte ska uppstå. Flödeshastighet. Avser hastigheten på mediet. Inloppstryck. Det tryck som kan mätas vid inloppet till pumpen. Ångtryck. Vid det tryck som mediet övergår till ånga. Densitet
