安徽农机所、中国农机院、湖北机械所和江苏农机所共同研制的WH微型混流泵,共9种规格,12种基本型及2种变型,于去年11月在湖北通过部级新产品鉴定,投入批量生产。该系列产品小巧轻便,结构合理,操作方便,使用可靠。填补了国内低扬程下使用效率高的微型泵系列产品的空白。部分产品效率超过机械工业部JB3559—84《单级离心水泵效率》标准。与日本JISB8313《小型离心水泵效率》标准要求相比,其效率的下限值比同流量的该
Anhui Agricultural Machinery Institute, China Agricultural Machinery Institute, Hubei Machinery Institute and Jiangsu Agricultural Machinery jointly developed WH micro-mixed flow pump, a total of 9 kinds of specifications, 12 kinds of basic types and 2 variants in November last year in Hubei through ministerial new product identification, Put into mass production. The series of compact and lightweight, reasonable structure, easy operation, reliable use. To fill the domestic use of low-head high efficiency miniature pump products blank. Part of the product efficiency exceeds the Ministry of Machinery Industry JB3559-84 “single-stage centrifugal pump efficiency” standard. Compared with the Japanese JISB8313 “small centrifugal pump efficiency” standard requirements, the lower limit of its efficiency than the same flow
