Resumo: The present research work conducted at Faculdade de Ciências Agrárias e Veterinárias da UNESP, "Campus" de Jaboticabal, São Paulo, Brazil, had as main objective the study of some parameters related to the quality of different spray nozzles such as: distribution pattern and liquid output. For the trial, pulverizing device with adjustable pressure, height and time spraying was built, which works in conjunction with the nozzle patternator made according to the World Health Organization specifications. Forty nozzles were tested under standardized conditions of pressure (40 PSI), spraying time (1 minute) and height (30 cm). The liquid discharge rate of each nozzle was compared with the liquid throughput specified by the manufacturer (or with the nozzle denominations code) and the volumetric distribution were presented graphically. The nozzles JD14-2 exhibited great uniformity of throughput between the replications (40 PSI). However, a significant deviation in the distribution pattern was detected. The difference suggests lack of standardization of the manufacturing process or poor control of the quality by the manufacturers.

Para os ensaios, foi empregado um equipamento pulverizador, com pressão de trabalho, altura e tempo de pulverização reguláveis, que funciona sobre uma mesa de distribuição volumétrica construída segundo as especificações da Organização Mundial de Saúde. Quarenta exemplares de bicos JD14-2 foram testados, padronizando-se, entre repetições, a pressão de trabalho (40 lb/pol2 ), o tempo de pulverização (1 minuto) e a altura (30 cm). A vazão de cada bico foi comparada com a vazão estipulada pelo fabricante (ou com o código de denominação do bico), e as distribuições volumétricas foram relacionadas em gráficos. Os bicos pulverizadores JD14-2 mostraram pouca variação de vazão na pressão de 40 lb/pol2. Entretanto, diferiram consideravelmente com relação ao padrão de distribuição volumétrica, sugerindo falta de padronização do processo de fabricação ou falhas no controle de qualidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGalli, Julio CesarArruda, Antonio Carlos de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16315Pesquisa Agropecuaria Brasileira; v.20, n.11, nov. 1985; 1239-1244Pesquisa Agropecuária Brasileira; v.20, n.11, nov. 1985; 1239-12441678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16315/10524info:eu-repo/semantics/openAccess2014-04-16T19:38:10Zoai:ojs.seer.sct.embrapa.br:article/16315Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:38:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
