Web2 dagen geleden · NPSH is the difference between suction pressure (stagnation) and vapor pressure. In equation form: NPSH = Ps ‑ Pvap. Where: NPSH = NPSH available from the system, at the pump inlet, with the pump running. P s = Stagnation suction pressure, at the pump inlet, with the pump running. P vap = Vapor pressure of the pumpage at inlet … Web(NPSH is de afkorting van Net Positive Suction Head). De NPSHbeschikbaar is voor een bepaald systeem in een bepaalde bedrijfssituatie een maat voor de druk die beschikbaar is aan de zuigaansluiting van de pomp. Dit is belangrijk om te voorkomen dat de vloeistof overgaat in dampvorm, met alle gevaren van dien.
