用高效混流泵新叶型技术 ,只更换叶轮 ,改造了循环泵 ;采取大小高效泵配置 ,大泵电机改双速并使用电机变极箱 ;实行两机三泵的运行方式 ;用考虑了水费用的循环泵经济调度图 ,实施循环泵经济 (成本 )调度及计算机在线管理 ,可在最佳真空或接近最佳真空工况下运行。综合上述诸项 ,全面地实现了循环泵系统的经济性优化
High efficiency mixed flow pump new leaf type technology, only to replace the impeller, the transformation of the circulating pump; to take the size of efficient pump configuration, the pump motor to double speed and the use of motor variable pole box; the implementation of two three pump operation; with water The cost of the circulating pump economic dispatch map, the implementation of circulating pump economy (cost) scheduling and online computer management, in the best vacuum or close to the best vacuum conditions. Based on the above, the economic optimization of circulating pump system is fully realized
