Analiza delovanja aksialne zobniške črpalke na osnovi zvoka in vibracij : zaključna naloga univerzitetnega študijskega programa I. stopnje StrojništvoTrček, SaraV zaključni nalogi obravnavamo delovanje aksialne zobniške črpalke na osnovi zvoka in vibracij do katerih prihaja med samim delovanjem. Zvok in vibracije so med seboj povezane preko akustičnega ... volumskega pretoka, ki se ustvari s premikanjem sevalne površine. Tako lahko z merjenjem ene veličine preko analizo pridemo do druge. Navadno najprej merimo hrup, in s pravilno analizo preidemo do vibracije površin, saj sta zvočni tlak in hitrost vibracij linearno povezani veličini. Pri obravnavani črpalki smo hoteli ugotoviti, zakaj nekatere izmed črpalk delujejo slabše. Primerjali smo merjeni hrup in vibracije črpalk z nedeformiranimi črpalnimi rotorji in z različno intenzivno deformiranimi črpalnimi rotorji. Izkazalo se je, da že minimalna deformacije rotorja poruši celoten obrat črpalnega rotorja, zato rotor deluje zelo nestabilno, puščanje pa je večje. Pri meritvah je opaziti, da črpalke z nedeformiranimi rotorji delujejo precej različno ter imajo različne hitrosti vibracij površin. Obravnavan je tudi kot naleganja črpalnega rotorja na črpalni stator, ki se izkaže za ključnega pri delovanju.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
