喷雾技术参数对雾滴飘移特性的影响

摘要

为了研究不同技术参数对雾滴漂移特性的影响,在可控风洞环境条件下测试了不同型号喷头在不同喷雾技术参数下的抗飘失能力,结果表明:喷头型号变小、喷雾压力和风速增大都增加了飘失对于喷雾高度变化的敏感程度,Lu喷头的敏感程度大于ID喷头;改变喷雾方向角对雾滴飘失的影响相对于风速、喷头型号并不显著.%In order to do the research on the influences of the parameters on spray drift, measurements of the drift potential under different wind tunnel conditions were made for different typical nozzles. The results showed that smaller type nozzle, larger spray pressure and wind speed could enhance the drift sensitivity along with the change of spray height, and the sensitivity of LU nozzles was more obvious than ID nozzles. Relative to the wind speed and nozzle type, the spray orientation has an inapparent influence on spray drift.
