为了研究压力和风对反映喷洒均匀性的喷头水量分布图的影响,本文作者用喷嘴直径为4.8mm、喷射仰角为7°的全园喷洒喷头,做了压力分别为:138KPa(低压)、276KPa(中压)和414KPa(高压);风速分别为:小于9.6Km/h(小风),9.6和20Km/h之间(大风)的6组试验,每组试验重复三次,每次试验持续150min,每次采集一百多个点的数据。对计算机绘出的三维图形观察研究得
In order to study the influence of pressure and wind on the nozzle water distribution that reflects the uniformity of spraying, the author used the whole garden spray nozzle with a nozzle diameter of 4.8mm and an injection elevation angle of 7 ° to make pressure of 138KPa (low pressure) and 276KPa ( Medium pressure) and 414 kPa (high pressure); wind speeds were: 6 sets of tests of less than 9.6Km / h (small wind), 9.6 and 20Km / h (gale), each of which was repeated three times for 150min, Collect more than 100 points of data each time. Observe the three-dimensional computer graphics
