Vpliv čistoče olja na hidravlični 4/3 potni ventil : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoBarbiš, DomenHidravlični sistemi so zelo pogosti v industriji in ostalih tehničnih področjih. Za krmiljenje se najpogosteje uporabljajo drsniški potni ventili, ki pa na krmilnih batih nimajo tesnil. To povzroča ... notranje puščanje. Stabilnost puščanja je zelo odvisna od čistoče hidravlične kapljevine. Diplomska naloga obravnava vpliv čistoče hidravličnega olja na trajnost in volumetrični izkoristek obravnavanega drsniškega potnega ventila. V okviru diplomske naloge je bilo zasnovano in sestavljeno hidravlično preizkuševališče, na katerem smo izvedli tri trajnostne teste hidravličnega 4/3 potnega ventila. Pri posameznem testu smo v hidravlično olje dodali različno količino testnega prahu MTD, ki je priporočen za izvedbo pospešenega testiranja. Ventil smo preklapljali s frekvenco 4 Hz do doseženih 2 milijona ciklov. Na ventilu smo merili notranje puščanje A in B voda s pomočjo dveh merilnih valjev in štoparice. Po izvedenih testih smo prerezali ohišja in pogledali obrabo drsnih površin ohišij in batov testiranih ventilov. Ugotovili smo, da se obrabljenost površin v notranjosti ventila s povečevanjem količine testnega prahu MTD v hidravlični kapljevini vidno povečuje, kar se opazi kot povečevanje notranjega puščanja ventila.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
