摘要
国内生产的薄壁滴灌带产品多以单流道形式为主,由于其基本结构存在缺陷,其产品在质量上存在流道易堵塞、滴水不均匀和流量互补功能差等一系列问题。针对这些问题,课题组经过2年的潜心研究,设计研制出一种迷宫和直流道相组合的新型复合流道薄壁滴灌带。试验证明,复合流道薄壁滴灌带具有良好的滴水均匀度和抗堵塞效果,同时还带一定的流量互补功能。
Domestic products of drip irrigation belt with thin wall are almost the type with single flow channel. On account of the structural shortage, the product has some problems such as easy-blocked flow channel, uneven drip and poor flow compensability, and so on. Aiming at above problems, through two years' hard work, the research team has designed a new type drip irrigation belt with thin wall and complex flow channel, which has both labyrinthic channel and straight channel. The experiment has proved that this new product had good uniformity of irrigation, good anti-clogging ability and certain flow compensability.
