SP-CV型循环水泵节能降耗改造研究

Research on Energy Saving and Consumption Reduction Transformation of SP-CV Type Circulating Pump

凝汽器真空偏低是影响火力发电厂运行的一项重大难题。就王曲电厂600 MW机组而言,循环水泵出力不足是造成机组真空偏低的主要原因。对该型循环水泵采取节能改造措施,以降低循环水泵出力不足对凝汽器真空的影响。

The low vacuum of the condenser is a major problem affecting the operation of thermal power plants. As far as the 600 MW unit of Wangqu Power Plant is concerned, the insufficient output of the circulating water pump is the main reason for the low vacuum of the unit. Therefore, the energy-saving retrofit of the circulating water pump is adopted to reduce the influence of insufficient circulation pump output on the condenser vacuum.
