供水技术,又称无负压供水技术,近年来已成为市政给水管网设计中经常使用的加压手段。该技术通过全封闭式的增压稳流设备,经微机控制变频调速来实现恒压供水,很大程度上解决了二次供水外部污染问题。但是,由于目前市政给水规范中,关于叠压供水仍缺乏相应的技术和产品标准,因此,在工程实践中,供水企业存在理解上的差异。本文通过对叠压供水技术的应用原理和推广应用存在问题进行探讨,并提出相应的建议,供同行参考。
Water supply technology, also known as non-negative pressure water supply technology, has become a commonly used means of pressurization in municipal water supply network design in recent years. The technology of closed-end pressurized steady flow equipment, the computer-controlled frequency control to achieve constant pressure water supply, to a large extent solve the secondary water supply external pollution problems. However, due to the current municipal water supply norms, there is still a lack of corresponding technical and product standards for over-pressured water supply. Therefore, there are understandable differences in water supply enterprises in engineering practice. This paper discusses the application principle of overlapping water supply technology and the existing problems of popularization and application, and puts forward corresponding suggestions for peer reference.
