适用范围
JB/T 5118—2001 本标准是对JB/T 5118—1991《农用污水污物潜水电泵 型式与基本参数》和JB/T 5119—1991《农用污水污物潜水电泵 技术条件》的修订与合并。修订时扩大了适用范围,调整了部分技术要求,增加安装方式等要求。 本标准规定了污水污物潜水电泵的型式、型号和基本参数,技术要求,试验方法,检验规则,标志、包装、运输和贮存等。 本标准适用于输送各类污水或含有泥沙、纤维物、粪便、河泥肥等不溶固相物的混合液体,流量为3.0m3/h~43350m3/h,扬程为1.4m~100m,功率为0.25kW~1600kW的单相或三相污水污物潜水电泵。 本标准于1991年以JB/T 5118—91、JB/T 5119—91首次发布,本次是第一次修订。
