摘要
在文献[1～3]的基础上，对设置导流锥、用肘形或簸箕形进水流道取代开敞式进水池以及更换水泵喇叭管等开敞式进水池的节能技术改造方法分别进行了优化水力计算，并根据进水泥道水力优化目标函数这个统一的尺度对它们进行了比较，以为确定最合理的中、小型轴流泵站进水池节能技术改造方案提供依据。
Based on the references [1 ～3]. the optimum hydraulic computations of the methods of technical modification of pump sump fOr energy saving are carried out. The methods include installing of a guide cone. replacing pump Sump with an elbow of Holland-type suction box and altering pump bellmouth. The results of the computations are compared in the light of the objective functions of the hydraulic pump sump for pumping station with small and middle size.
