| 摘 要： | 针对高含沙黄河水滴灌系统滴头堵塞的问题,根据滴头堵塞的内因和外因,采取内外结合、双管齐下的技术思路对首部和尾部系统进行改装。对首部的泥沙分离器进行结构优化和改进,提高其对水源中固体颗粒的分离效率,将造成滴头堵塞的外因降低;对尾部的滴头内部流道进行重新设计,在保证消能效果的前提之下,缩短流道长度和放大流道尺寸,增强滴头本身的抗堵塞能力和抗老化问题,从而解决了滴灌技术推广中的关键技术。

| Abstract: | For emitter congestion problems of high sediment Yellow River water drip irrigation,head and tail systems were modified according to internal and external factors of emitter congestion.The structure of sediment separator was optimized.The separative efficiency was improved.External factor of emitter congestion was reduced.The internal port of emitter was redesigned.Shorten the length and magnified port flow size were applied to enhance anti-clogging and anti-aging ability.The key technologies of drip irrigation system were solved. |
