综述了国内外摇臂式喷头的发展历程和未来趋势,详细分析了近期摇臂式喷头的新型结构与适用特点,结合我国实际情况论述了我国在摇臂式喷头的研究与生产中存在的研究手段单一、研究力量单薄、企业缺乏产业化等问题。提出要应用新发展的计算流体动力(CFD)、计算结构动力学(CSD)和粒子成像速度场仪(PIV)等技术进行喷头基础理论研究,加强联合攻关,建立质量监督体系等发展摇臂式喷头的对策和建议。
The developing history and trend of impact sprinklers were summarized and the latest popular structures and corresponding characteristics of impact sprinklers were introduced. The main problems existed in research and manufacture of impact sprinklers in China were analyzed, Some proposals, such as application of new technologies in computational fluid dynamics, computational structure dynamics and particle image velocimetry, strengthening academic cooperation and building up system of quality supervision, were suggested, which would promote the development of impact sprinklers in China.
