摘要
本文按微灌对水质的要求,并根据国内外的实践经验,提出了如何正确地确定过滤器设计的有关参数。另外按水力学原理提出了确定滤网过滤器的大小和水力性能的设计计算方法。
Screen filter is one of the most important equipment in micro irrigation system. However few data about its proper design are available at home. This paper describes how to determine its designing parameters correctly in accordacce with the requirements of micro-irrigation for water quality, and the practical experience at home and abroad. Moreover, this paper presents a desiging method of determing the size and hydraulic theory.
