滴头抗负压堵塞标准测试系统浅析

Standard Test System for the Resistance to Negative Pressure Blockage of Water Emitter

本文介绍了地下滴灌抗堵塞试验简况,提出了滴头抗负压堵塞的测试系统和测试方法,经测试验证,可操作性强,可用于快速评价滴头抗负压堵塞的能力,以及筛选适宜于地下滴灌用灌水器等,并已被现行国家标准所采纳,供有关生产、应用、检验和评价等单位使用。

In this paper,the anti-clogging test of subsurface drip irrigation is introduced,and the anti-negative pressure clogging test system and test methods of emitters are presented.The test results show that the operability is strong and can be used for rapid evaluation of anti-negative pressure clogging ability of emitter,as well as selection of suitable for subsurface drip irrigation emitter,which has been adopted by the current national standards for the production,application,inspection and evaluation agencies to use.
