离心泵叶轮切削节能改造应用

由于离心泵设计与热电厂生产运行中的差距，在水泵运行和设备改造带来了离心泵性能曲线与高效区的偏离，带来了电能的极大浪费，这就需要通过更改最少的部件和最低的成本，使离心泵性能参数得到校正。通过车削离心泵叶轮切割的试验及方法，改变运行工况，得出快捷、可靠的离心泵节能方法。

Application of Vane Cutting of Centrifugal Pump to Save Energy

Due to difference between the design of centrifugal pump and production op-eration of the thermal power plant, operation and equipment modification of the water pump led to deviation of the centrifugal pump performance curve from high efficiency range, result-ing in big waste of electricity. Thus the performance parameters of the centrifugal pump needed to be corrected with minimum replacement of parts and minimum cost. A fast and reliable energy saving method for the centrifugal pump was obtained by experiment of turning of centrifugal pump vanes to modify operation condition.
