Abstract

Widespread use of electronic regulators, in order to correlate the working parameters at sprinkling machines imposes making a study to assess the performances of the regulation process in working conditions. To achieve this objective were pursued the following aspects: adequate choice of system components; the achievement in own conception of a electronic regulator for automatic correlation of liquid flow with displacement velocity; choosing and preparing a sprinkling machine on which will be installed the achieved control system, in order to perform tests under field conditions. Analysis of the evolution in time of the adjustment process under field conditions consisted in recording and analyzing data relating to the automatic correlation of liquid flow with displacement velocity. In order to achieve a comparative study of the sprayer were performed tests, in the conditions of variable displacement velocities, with the adjusting system connected, respectively disconnected. For obtaining data was used a simple quantitative method for collecting the dispersed particles, based on samples of absorbent paper, followed by the quantitative analysis of samples by weighing, data acquisition and processing in the computer system. The comparative study achieved during tests highlights the necessity to equip the sprinkling machinery with electronic controllers, which ensures a superior adjustment process imposed by agro-technical requirements.
