Tlačne razmere znotraj hidravličnih sistemov s potnimi, tokovnimi in tlačnimi ventili : diplomska naloga visokošolskega strokovnega študija
Ferlat, David
V diplomskem delu so predstavljeni stanje tehnike in fizikalne osnove naloge, ki temeljijo na hidrostatičnih in hidrodinamičnih lastnostih kapljevin. Prikazane so lokalne izgube skozi določeno ...hidravlično sestavino in izračunane linijske izgube po ceveh. Po pregledu uporabljenih hidravličnih sestavin ter opisu in opredelitvi posamezne meritve je prikazanih devet različic hidravličnih sistemov s pripadajočimi grafičnimi rezultati meritev in analizo tlačnih razmer znotraj sistema. Merili smo pomik batnice hidravličnega valja in tlake na vseh funkcionalno pomembnih mestih. V zadnji, deseti različici sistema, pa je uporabljen tudi proporcionalni potni ventil. Z analizo in primerjavo rezultatov meritev sta prikazana vpliv položaja (povečanje tlaka na 166,2 bar) in vpliv vrste (nespremenjena sila 28,7 kN) hidravličnih sestavin na pogonski in zaviralni hidravlični valj, ter vpliv uporabe proporcionalnega potnega ventila.
