摘要
针对工作压力及喷射角度对微喷带单孔喷水特性的影响进行了试验,通过对微喷带单孔喷洒射程、湿润区宽度、干燥区宽度、水滴直径以及工作状态下微喷带直径的研究分析,发现:喷射角度为30°时,微喷带单孔喷洒射程达到最大值;湿润区宽度随着喷射角度和工作压力的增大而增大;工作压力为20 k Pa时,微喷带喷洒性能参数曲线波动明显,不宜在实际生产实践中应用;工作压力和喷射角度变化对水滴直径并没有明显影响;工作状态下微喷带直径的稳定程度反映了微喷带喷洒性能的稳定程度。
In this paper, the influence of working pressure and spraying angle on the single hole spraying characteristics of micro-sprinkling hoses is studied. Based on the analysis of the spraying range, the width of the wetting zone, the width of the drying zone, the diameter of the water drop and the working diameter, the following results were obtained. Under the test pressure, the range reaches the maximum when the spray angle is 30 degrees ; the width of wetting zone increases with the increment of angle and pressure; the width curve of dry zone is similar to that of the range curve; when the working pressure is 20KPa, the performance parameter curve fluctuates obviously, which is not suitable for the practical design and application ; the working pressure and spraying angle have no significant effects on the droplet diameter; the stability of the micro spraying band diameter reflects the stability of spraying performance.
