针对某大型化工企业循环水系统存在的“大马拉小车”现象和水泵长期处于“大流量、超扬程”的偏设计工况运行的特点，提出采用“三元流技术”对水泵进行纠偏节能技术改造，通过更换高效三元流叶轮达到提高水泵运行效率及降低能耗的目标。实施改造后，水泵效率提高近10％，单台水泵每年节约电能76．8万kW·h，节能效果显著。

침대모대형화공기업순배수계통존재적“대마랍소차”현상화수빙장기처우“대류량、초양정”적편설계공황운행적특점，제출채용“삼원류기술”대수빙진행규편절능기술개조，통과경환고효삼원류협륜체도제고수빙운행효솔급강저능모적목표。실시개조후，수빙효솔제고근10％，단태수빙매년절약전능76．8만kW·h，절능효과현저。
Focused on the energy loss phenomenon and characteristic of pump being in“high flow and head”partial design con-dition too long,the energy efficiency renovation to pump was proposed using three dimensional flow technique,it realized the effect of increasing efficiency and reducing energy consumption based on renewing high efficiency impeller.After the renovation,the ef-ficiency of the pump increased nearly 10 percent,a single pump saved electric energy 76.8 kW·h each year,the energy saving effect was remarkable.
