Energy aspects of sprincler irrigation

Abstract

This research has included two different raining irrigation systems, both rain gun and mobile linear system. According to the calculations, can be concluded that those two systems work with different pressures, which causes different losses in the pipe line. Reason for significantly higher losses (1,7 bar) and consequently higher energy consumption (131 kW/ha) at self propelled rain gun is that water energy in this case is used for rolling the hose and movement of the sprinkler. At mobile linear system, the movement is propelled by electro motors and, at the same time, this system works with significantly lower pressures, which means lower energy consumption, as well (45,28 kW/ha).

Istraživanjima su obuhvaćena dva različita sistema navodnjavanja kišenjem i to samohodni kišni top i mobilni linearni sistem. Na osnovu proračuna može se zaključiti da ova dva sistema rade sa različitim pritiscima, a samim time i gubitci u cevovodu su različiti. Razlog znatno većim gubicima (1,7 bar), a time i većoj potrošnji energije (131 kW/ha) kod samohodnog kišnog topa leži u činjenici da se energija vode u ovom slučaju koristi za namotavanje creva odnosno za kretanje prskača. Kod mobilnog linearnog sistema za kretanje se koriste elektro motori, a sem toga ovaj sistem radi sa znatno nižim pritiscima pa je samim time i potrošnja energije manja (45,28 kW/ha).
