DURABILITY EVALUATION OF A PULVERIZATION SYSTEM COMPONENTS, ATTACHED TO CENTRAL PIVOT

This work aimed to evaluate the durability and performance of the pulverization system prototype (NOTLIADA) attached to center pivot irrigation system. The flow emission sets, electronic actuation, solenoid valve and the adaptation of a polyvinyl chloride (PVC) pipe were evaluated. Tests were performed on a prototype system, riding in the Laboratorio de Hidraulica of the Departamento de Engenharia de Biossistemas, belonging to the Escola Superior de Agricultura "Luiz de Queiroz" - ESALQ /USP. The results showed no change, 5% significance level, in the flow of the four different emission sets tested in intermittent evaluation and also, no significant variation of the emitters diameters. The circuit electronics, solenoid valve, pipe and other devices of the spray bar operated satisfactorily during the same period of evaluation confirmed the reliability of the pulverization system developed.
