Study of the Working Performances of Automated Sprinkling Machinery: Study of the Process of Electronic Flow Regulation for Sprinkling Machines - Tapa blanda

Sinopsis

The widespread use of electronic regulators in the construction of sprinkling machines has required the study of the adjustment performance achieved by these equipments, in specific working conditions. Study of the electronic adjustment process of the liquid flow was performed under laboratory conditions, by simulating on a stand the real operating process and also in working condition. The analysis of the obtained results highlights in case of change of the displacement velocity a prompt response of the adjusting system, being necessary approx. 7.0 s for flow correction. The predominance of errors between 10% and 15% is not excessive and the cumulative value of the surfaces on which the prescribed liquid norm has not been ensured is insignificant. In order to achieve a comparative study of the sprayer under field conditions were performed tests, in the conditions of variable displacement velocities, with the adjusting system connected, respectively disconnected. The obtaining data highlights the necessity to equip the sprinkling machinery with electronic controllers, which ensures a superior adjustment process imposed by agrotechnical requirements.
