随着我国供水事业的发展,许多城市水压、水量和保证率都有了不同程度的提高,为了充分利用市政管网水压,确保供水水质,管网叠压(无负压)供水设备应运而生。该项技术以其节能、省地、污染少等特性被市场认可并大力推广。为了占领市场,各式管网叠压(无负压)供水设备的研发、设计和生产在国内正方兴未艾。目前,针对无负压供水设备的已编和在编标准达8本之多,市场上有近千家的无负压供水设备生产企业,而基于不同设计理念、技术标准生产的无负压供水设备优劣争议正大量进入公众视野。鉴于此,为促进管网叠压(无负压)供水技术的有序发展,为设计人员提供设备选用指导,推动管网叠压(无负压)供水设备市场健康发展,6月29日,全国给水排水技术信息网和《给水排水》杂志社联合主办的“水技术沙龙(一)”就管网叠压(无负压)供水设备的类型之一——箱式无负压供水技术的背景、工作原理、应用条件、核心系统、供水安全和可靠性等问题,请有关专家进行了深入的交流和讨论,本刊整理了部分观点,供读者参考。如果读者有疑义或不同观点请发送至[email protected]。
With the development of water utilities in the country, many cities water pressure, water quantity and have a guaranteed rate improved to varying degrees, in order to make full use of municipal pipe network water pressure to ensure that the quality of water pipe network layers (no vacuum) water equipment should be shipped And students. The technology is recognized and promoted by the market for its energy saving, land saving and less pollution. In order to occupy the market, all kinds of pipe network overlay (no negative pressure) water supply equipment research and development, design and production are rising in China. At present, for the negative pressure water equipment has been edited and compiled in the standard of 8 as much as there are nearly a thousand of negative pressure water equipment manufacturers on the market, based on different design concepts and production, technical standards no negative pressure water supply equipment Pros and cons disputes are entering the public view. In view of this, in order to promote the orderly development of the pipe network layers (no vacuum) water technology, provides designers with equipment selection guide, push pipe network layers (no vacuum) water equipment and healthy development of the market, June 29, one type National water supply and drainage technology information network and “water and Wastewater” magazine co-hosted the “water technology salon (a) ” on the pipe network layers (no vacuum) water equipment - box no negative pressure water bACKGROUND issues, working principle, application conditions, the core system, water supply security and reliability, please experts conducted in-depth exchanges and discussions, the magazine compiled a partial view, for reference.
