循环水泵节能降耗的途径与实践

Approach of Energy Saving and Consumption Reduction of Circulating Water Pump and Its Application

华电莱州一期循环水系统采用海水为水源的直流供水系统,针对不同季节气温变化、微生物繁殖情况以及不同时间潮汐等特点,致使不同季节同一负荷下循环水温和循环水量会出现大幅度变化,从周期性半侧冲洗、循环水泵运行方式优化、循环水系统用户3个方面进行综合分析与优化,得到最佳运行方式,以达到节能降耗良好效果。

The circulating water system in Huadian Laizhou Phase I Project adopts once-through water supply system using seawater as the water source. According to the characteristics that seasonal air temperature changes, microorganism reproductions and tidal differences would cause substantial increase of the circulating water temperature and volume at the same loads and time the comprehensive analysis and optimization are conducted in the aspects such as periodic half side flushing, circulating water pump operation modes and circulating water system users and the optimal operation mode is obtained, which enables better energy saving and consumption reduction.
