Projekat

Sažetak

U ovom radu je primenjena metoda faktorijalnog eksperimenta za proučavanje uticaja faktora na protok i zapreminski stepen iskorišćenja gerotor pumpe. Razmatrani faktori su koeficijent poluprečnika trohoide, broj obrtaja pogonskog vratila pumpe i radni pritisak, pri čemu je prvi faktor geometrijski parametar, a ostali su radni parametri. Faktorijalni dizajn i metod površinskog odziva su primenjeni za procenu i optimizaciju efekata parametara na protok i zapreminski stepen iskorišćenja. Korišćen je dizajn eksperimenta 33 kod koga svaki faktor ima tri nivoa. Analizom razmatranih faktora dobijena je njihova optimalna varijanta, i to: koeficijent poluprečnika trohoide 1.375, broj obrtaja pogonskog vratila pumpe 2000 o/min i radni pritisak 1 bar, pri kojoj se dobija najveća vrednost protoka i najveća vrednost zapreminskog stepena iskorišćenja. Razvijen je matematički model za predviđanje protoka i zapreminskog stepena iskorišćenja u pogledu već navedenih parametara.
