Valtura System Hydraulic Analysis with Improvements

U ovom završnom radu analiziran je sustav navodnjavanja Valtura u svrhu smanjenja tlaka na hidrantima. U prvom poglavlju opisani su dijelovi sustava Valtura, analizirana je pumpa crpne stanice te je prikazana njihova tehnička dokumentacija. U drugom poglavlju obrađeni su zakoni rada pumpi te gubitci u sustavu. Nadalje, opisan je program AFT Fathom 9 u kojem je provedena analiza sustava. Odabirom nove pumpe VS 46-20/1 (2-6) ∅ = 460 iz kataloga „Croatia pumpe“ smanjili smo tlak na hidrantima. Sustav radi ispravno, a tlakovi na hidrantima su zadovoljavajući.This thesis analysis the irrigation system Valtura in purpose od pressure reduction on the hydrants. First chapter describes the parts of the irrigation system Valtura, analysis the pump in the pump station and it gives their technical documentation. The general principles of pump work and the system losses are described in the second chapter. Furthermore, the AFT Fathom 9 software which was used for system analysis is described. The pressure on the hydrants is reduced with the new pump VS 46-20/1 (20-6) ∅ = 460, which was choosen from the catalog of „Croatia pumpe“. The system works correctly and the pressure on the hydrants are satisfying
