本标准是在CJ/T176—2002《旋转式滗水器》基础上修订完成的,本标准与CJ/T176—2002相比主要变化如下:
———对滗水器术语的定义作了适当的调整,增加了单池面积、滗水器数量、滗水时间、滗水速度的定义。
———在分类中按滗水量给出了滗水器的型号排列序列,使之具有更好的可操作性。
———在性能参数方面,根据滗水器在近几年使用中的实践经验和技术发展,对滗水量、堰口负荷、滗水速度等参数都作了适当调整,使之更适应现在污水处理工艺的需要,更加注重与工艺的协调。
———在要求方面,增加了对影响滗水器本身工作性能的条文:滗水器运行的控制方式应采用程序控制或智能控制。
———在检验方法方面,增加了重要的检验条文:整机空载检验、整机运行试验、机械过扭矩保护检验、滗水器总装检验、绝缘性能检验和耐电压检验、智能控制方式的滗水器功能检验、首次无故障工作时间等检验项目及其对应的检验方法。
———在检验规则方面,增加了整机运行、智能控制、绝缘性能及耐电压等主要工作性能检验规定。
———增加了对产品的贮存要求。本标准规定了旋转式滗水器(以下简称滗水器)的术语和定义、分类与型号、型式、性能参数、要求、检验方法、检验规则、包装、运输、标志、贮存等。本标准适用于城镇污水处理、工业废水处理等工程中应用的滗水器。
