非接触式逆止器在大型排灌站中的应用研究

Application and Research of Non-contact Backstop in Large-scale Irrigation and Drainage Stations

阐述了大型排灌站立式混流泵反转的危害性。同时,分析了FXM型非接触式逆止器的结构、工作原理以及性能特点。结合某市排灌站建设实践,提出了非接触式逆止器选型计算依据,并强调了逆止器安装与维护技术要点。实践表明,非接触式逆止器应用于大型排灌站立式混流泵的反向制动是最佳的技术方案。

Standing on a large - scale irrigation and drainage - type mixed - flow pump reverse harmful. An analysis of non- contact type FXM backstop structure, working principle and performance characteristics. Combination of Yellowstone Lake to spend the practice of building drainage and irrigation stations, put forward a non - contact backstop Selection is based on and stressed the backstop installation and maintenance techniques. Practice shows that non - contact backstop used in large - scale irrigation and drainage standing mixed - flow pump reverse braking is the best technical solutions.
