摘要
在试验室内，对研制的微压灌水器进行了水力性能试验。试验结果表明：在微压（2～5m）工作时，新型微压滴灌灌水器在自由出流状态下的出流规律符合设计要求；在工作压力范围内，微压灌水器的流量稳定，变化小；新型微压滴灌灌水器在连续工作1周后流量略有变化，出流更加均匀；微压滴灌灌水器抗堵塞能力强，性能可靠。
Two types of the tiny pressure drip irrigation emitter are placed on the experimental stage in laboratory, and the tiny pressure emitters are carried on experiment at free flow. The experimental result shows that the flow regulation of new tiny pressure drip irrigation emitters meets the design request at tiny pressure（2 to 5 m）. Within the scope of work pressure, the discharge of new tiny pressure drip irrigation emitters changes small. After working for a week continuously the discharge has a little variation, and the flow is more even. The against clogging ability of tiny pressure drip irrigation emitters is strong, and hydraulic property is dependable.
