【摘要】 本文讨论了三种主要的行喷机组(平移式、中心支轴式和绞盘式)的均匀度设计和计算问题,提出了均匀度设计的一般原则和计算行喷机组均匀系数的基本公式及理论推算方法,并用实测结果做了验证。为便于喷灌机组设计的实际应用,对于一些基本分布图形,文中给出了在不同间距下计算均匀系数的图和表。更多还原

【Abstract】 In this paper some problems about the design and calculation of uni- formity of three major types of continuonsly moving mechanical sprin- kler systems(straight moving lateral. center pivo and trave or) are dealt with. The general rules of the design of uniformity, the basIc formulas and the method of theorization of calculating uniformity coefficient of continuously moving sprinkler systems are mentioned here in comparison with experimental. results. The charts of calculating uniformity coefficient in different distance of some basic patterns are also given in order to help the design of the sprinkler system.更多还原
