摘要
为了达到节约原材料,降低潜水泵的制造成本,同时提高单级扬程和使用可靠性,研制一种较现行400QJ500型潜水泵流量大、扬程高、且适用于小井径的新型潜水泵。新型350QJ500潜水泵增大了进口流速,减小了叶轮吸入口直径和叶轮外径;同时减小叶片包角,将叶片由全扭曲改为半扭曲,使其具有生产成本低、结构合理、高效节能、运行平稳、安装使用方便、适用性广等特点。
In order to save materials, reduce manufacturing cost of submersible pump, and improve single-stage lift and reliability, a new submersible pump with bigger flow, higher head and slimmer hole were developed. Larger inlet velocity was chosen to reduce the impeller inlet diameter and impeller diameter; Leaves of submersible pump were changed from distorted to a semi-distorted to reduce the blade wrap angle; It has the following advantages： lower production cost, reasonable structure, high efficiency, energy saving, stable operation, easily installation and wide applicability.
