摘　　要：对电站汽轮机循环水泵进行高低速改造,是提高机组运行经济性的一项重要措施。通过循环水泵流量-扬程特性和循环水系统阻力特性的匹配性分析,可以分析计算循环水泵在不同运行方式下的运行工作点,为循环水泵高低速改造可行性提供直接依据。以某300MW机组循环水泵高低速改造可行性分析为例,介绍了分析过程和分析结论,形成了循环水泵高低速改造可行性分析方法,对循环水泵高低速改造工作具有重要指导意义。High and low speed reform of circulating water pump is an important method to improve unit operation economy. Through matching analysis between flow - head characteristics of circulating water pump and resistance characteristics of circulating water system, the operation points of different operation modes can be analyzed to provide evidence for high and low speed reform of circulating water pump. Taking the feasibility analysis of a 300MW unit circulating pump as an example, this paper introduces the analysis process and analysis conclusion, and forms a feasibility analysis method for the high and low speed transformation of circulating water pump, which is of great significance to the high and low speed transformation of circulating water pump.
