Resumo: The spray nozzles manufacturers constantly offer new models in the market attempting to increase the application efficiency; however, the nozzles behavior is often unknown in relation to the produced droplets spectrum. Thus, this work was carried out aiming to evaluate the droplets spectrum provided by the AI3070-015VP and AI3070-02VP nozzles. These nozzle tips have two tilted sprays (30 and 70°) both with air induction. In the spectrum analysis, it was used the laser particle analyzer (Spraytec, Malvern Instruments Co.) which has a 750 mm focal lens. It was built a system to analyze the spray jets produced by the nozzles individually. The spraying technical parameters (DV0,1, DV0,5, DV0,9, Span Index, %V650 ?m) were performed in four working pressures (200, 300, 400 and 500 kPa). The experiment was conducted in a completely randomized in a factorial scheme (2 x 2 x 4), two models of nozzle sprayer, two fan and four working pressures. For the AI3070-015VP nozzle, the tilted 70° spray produced droplets with coarser volume median diameter (VMD) comparing to the tilted 30° spray, whereas for the AI3070-02VP nozzle, the behavior was the opposite. The nozzles tested showed low drift potential, with %V

Sendo assim, este trabalho foi conduzido com o objetivo de avaliar o espectro de gotas proporcionado pelas pontas AI3070-015VP e AI3070-02VP. Estas apresentam dois jorros de pulverização defasados em relação à vertical (30 e 70°), ambos com indução de ar. Na análise do espectro, utilizou-se um analisador de partículas a laser (Spraytec, Malvern Instruments Co.) dotado de lente focal de 750 mm. Construiu-se um sistema para analisar individualmente os jorros produzidos pelas pontas. Realizaram-se as análises dos parâmetros técnicos da pulverização (DV0,1, DV0,5, DV0,9, Índice Span, %V < 100 ?m e %V > 650 ?m) empregando-se quatro pressões de trabalho (200, 300, 400 e 500 kPa). O experimento foi conduzido em delineamento inteiramente ao acaso, em esquema fatorial (2 x 2 x 4), sendo dois modelos de pontas hidráulicas dois leques e quatro pressões de trabalho. Para a ponta AI3070-015VP o jorro produzido com ângulo de 70° produziu gotas com maior diâmetro da mediana volumétrica (DMV) em relação ao de 30° ao passo que, para a ponta AI3070-02VP, o comportamento foi o inverso. As pontas testadas apresentaram gotas com baixo potencial de deriva, com %VUniversidade Federal de Viçosa - UFV2016-08-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/55910.13083/reveng.v24i3.618Engineering in Agriculture; Vol. 24 No. 3 (2016); 211-218Revista Engenharia na Agricultura - REVENG; v. 24 n. 3 (2016); 211-2182175-68131414-398410.13083/reveng.v24i3reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/559/382Sasaki, Robson ShigueakiTeixeira, Mauri MartinsMaciel, Christiam Felipe SilvaAlvarenga, Cleyton BatistaForastiere, Paulo Robertoinfo:eu-repo/semantics/openAccess2023-01-19T13:31:08Zoai:ojs.periodicos.ufv.br:article/559Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:31:08Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
