基于系统方法的水泵系统节能潜力分析及应用

Energy Conservation Potential Analysis of Water Pump System and Its Application Based on System Method

通过对水泵系统常见调节方式的系统运行效率和节能潜力分析,指出系统的优化方案应建立在对系统进行全面测试和分析上。两个节能改造案例表明:水泵系统节能潜力巨大,应用适当扬程和流量的水泵更换原处于低效区运行的水泵,在此基础上再应用变频技术将会取得可观的节能效果和比较短的投资回收期。

According to the analysis of operation efficiency and energy saving potential of different regulation methods in pumping system, it is pointed out that system optimization should be based on overall system measurements and analysis. Two successful energy saving case studies demonstrate that a big energy saving potential exists in pumping system. Replacing original water pumps with new pumps of proper head and flow, then applying VFD techniques on new pumps will lead to considerable energy saving and very short pay back.
