【摘要】 为提高微喷灌在湿润面积上的均匀性，本文选出三种具有代表性的微喷头，测出了其水力性能特征，画出了水量分布图，进行了不同间距和不同布置形式的组合，以组合喷洒均匀系数为主要评价指标，探讨了微喷头组合的最佳布置形式。经分析：水轮型微喷头的布置间距以（０．８５～０．９２）Ｒ、水雾型微喷头的布置间距以（１．３０～１．３６）Ｒ时，其组合喷洒均匀系数较高，喷洒效果比较理想，可供设计者参考。更多还原

【Abstract】 To improve the microsprinkle spray uniformity on its moistening scope,three representative microsprinklers have been choosed to measure the hydraulic characteristics and draw the water distribution map,design the various spacings and its arrangement styles.Taking the uniformity coefficient of combined spray as an index,the optimum style of microsprinklers arrangement are discussed.This paper finds that(0.85￣0.92)R(R is a spray penetration)for turbine microsprinklers and(1.30￣1.36)R for fogtype microsprinklers are suitable,thus,the uniformity coefficient is higher and desirable.This paper is a reference for designer.更多还原
