Sažetak
Pravilnom zaštitom i kvalitetnim radom prskalica omogućuje se optimizacija aplikacije pesticida i smanjuje štetni uticaj na životnu sredinu i zdravlje ljudi. Efikasnost izvedene zaštite ogleda se sa više aspekata a jedan od najznačajnijih je kvalitet rada prskalica, odnosno uniformnost distribucije pesticida rasprskivačima. Rad predstavlja analizu i upoređenje rezultata ispitivanja u sklopu inspekcijske kontrole ratarskih prskalica u eksploatacionim uslovima centralne Srbije, u skladu sa evropskim normama EN 13790 koji propisuje metode i opremu za obavljanje inspekcije. Cilj istraživanja je bio da se utvrdi kvalitet rada prsaklica i uniformnost protoka različitih rasprskivača u zavisnosti od definisanih parametara. Za ispitivanje je korišćena merna oprema 'AAMSSALVARANI', a protok rasprskivača je meren pomoću ispitivača pojedinačnih rasprskivača SN S001. Na osnovu dobijenih rezultata zaključeno je da su prosečne vrednosti protoka rasprskivača iznosile 0,954 l min-1 (tip A), 1,169 l min-1 (tip B), odnosno 1,190 l min-1 (tip C), pri čemu je koeficijent varijacije bio u rasponu 12,24% do 29,49%.
Abstract
Proper protection and quality work of sprayer enable the optimization of the pesticide application and reduces the harmful effects on the environment and human health. The efficiency of the implemented protection is reflected in several aspects, and one of the most important is the quality of the work of sprayers, that is, the equality of pesticides distribution with nozzles. The paper presents an analysis and comparison of test results in the framework of the inspection of field crop sprayers in the exploitation conditions of central Serbia, in accordance with European standards EN 13790, which prescribes methods and equipment for inspection. The aim of the research was to determine the quality of the work of chests and the uniformity of the flow of various sprays, depending on the defined parameters. The test equipment used 'AAMSSALVARANI' measuring equipment, and the flow of the nozzles was measured by the SN S001 individual nozzles. On the basis of the obtained results, it was concluded that the average values of the flow of the sprayer amounted to 0.954 l min-1 (typ A), 1.169 l min-1 (typ B), or until 1.190 l min-1 (sprayer typ C), where the coefficient of variation was in the range 12.24% to 29.49%.
