The goal of the research was to determine the level of abrasion of different types of nozzles during different types of uses and at different pressure values.
The experiment assembly consists of an ATOM-300 carried sprayer, manufactured by S.C. TEHNOFAVORIT S.A. Bonţida-Cluj, and a stand for testing the distribution uniformity of the vineyard and orchard sprayers Herbst ED20-900, manufactured by Ernst Herbst Prüftechnik e. K. Hirschbach-Germany.
The 4 types of nozzles used were Lechler Ceramic 1.0 and 1.2; Lechler TR 80-30 and Lechler ITR 80-015 with air induction.
The measurements were made on a water pressure of 10 bar and 20 bar, and the testing period was equivalent with the duration of a campaign. The study below presents the variations of the debit measured in each type of nozzle according to the time and pressure.
