In this range of air-water ratio the flow rate of mixture slightly decreased, the axial power increased linearly and the pump efficiency increased parabolically with a rise in effective head.
在稳定工作区范围内，不同的含气量条件下，随着排出压头的增加，混合液总量稍有下降，轴功率直线上升，效率呈抛物线变化。
After retrofit of no. 1 circulating-water pump pole-change in Jiujiang power plant, energy saving effect is obvious, it can reduce service power rate and increase total economy of units operation.
