摘　　要：为改善射流脉冲喷头的径向水量分布,基于射流脉冲喷头的“双驼峰”式水量分布以及挡水板结构的特点,创新了一种“槽型”驱动板结构,并进行了正交试验,得到一种新型结构的射流脉冲喷头.发现“槽型”驱动板的各结构因素对射流脉冲喷头喷灌均匀度影响的主次顺序及最优结构为内槽倾角13°、驱动板长度16 mm、槽宽3 mm、侧驱动板倾角17°、驱动板宽度11 mm.当进口压力为0.15,0.20,0.25,0.30 MPa时,开展了“槽型”射流脉冲喷头、原射流脉冲喷头与摇臂式喷头水力性能对比试验.试验结果表明:在0.15~0.30 MPa的进口压力下,新喷头进口流量相比原喷头进口流量减小0.12~0.17 m3/h,相比摇臂式喷头进口流量减小0.07~0.16 m3/h.“槽型”射流脉冲喷头喷灌均匀度比原射流脉冲喷头提高1.25%~7.43%,比摇臂式喷头高7.84%~14.42%.综合分析表明“槽型”驱动板结构设计合理,对射流脉冲喷头的喷灌均匀性改善显著.研究可为该型国产喷头后续研发和工程应用提供理论参考与数据支撑.In order to improve the radial water volume distribution of the jet pulse sprinkler, based on the ″double hump″ type water volume distribution of the jet pulse sprinkler and the characteristics of the water baffle structure, innovative the ″groove-type″ drive plate structure, and the orthogonal test was carried out to obtain a new type of the jet pulse sprinkler. The results show that the primary and secondary order factors, which affect the optimal structure of jet pulse sprinkler irrigation on the uniformity, are that the inclination angle of the inner groove is 13°, the length of the driving plate is 16 mm, the groove width is 3 mm, the inclination angle of the side drive plate is 17°, and the width of the driving plate is 11 mm. When the inlet pressure is 0.15, 0.20, 0.25 and 0.30 MPa, the hydraulic performance comparison test of the ″groove-type″ the jet pulse sprinkler, original jet pulse sprinkler and rocker arm sprinkler was carried out. The test results show that under the inlet pressure of 0.15-0.30 MPa, the inlet flow rate of the new sprinkler is reduced by about 0.12-0.17 m~3/h compared with the inlet flow of the original sprinkler, and the inlet flow rate of the new sprinkler is about 0.07 m~3/h-0.16 m~3/h smaller than that of the rocker sprinkler. The uniformity of the sprinkler irrigation of the ″groove-type″ new sprinkler is 1.25%-7.43% higher than that of the original sprinkler, and 7.84%-14.42% higher than that of the rocker sprinkler. The comprehensive analysis shows that the structural design of the ″groove-type″ drive plate is reasonable, and the uniformity of irrigation to the nozzle is significantly improved. This study can provide theoretical reference and data support for the subsequent research and development and engineering application of this type of domestic sprinkler.
