Napoved kavitacije v črpalki s 3D ozobjem : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoBratuš, ŠpelaMagistrsko delo obravnava pojav kavitacije v zobniški črpalki s 3D aksialnim ozobjem. Z metodo neto pozitivne sesalne višine so bile določene kritične obratovalne točke črpalke. Metoda definira padec ... hidravlične moči črpalke kot merilo za pojav kavitacije. Izvedene so bile hidravlične meritve za določitev zahtevane neto pozitivne sesalne višine črpalke. Na njih je bila nato zasnovana enačba za napoved kritičnega podtlaka v odvisnosti od pretoka in vrtilne frekvence. Med izvajanjem hidravličnih meritev je bila postavljena hipoteza, da se kavitacija pojavi preden zaznamo padec hidravlične moči. Predpostavka temelji na zaznanem povišanju hrupa pred kritičnim podtlakom, ki ga določimo z metodo preko neto pozitivne sesalne višine. Dano hipotezo potrdimo z meritvami hrupa in vibracij.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [Š.
