摘要
为跟随季节和负荷的变化,凝汽器循环水供水量通常只有依靠增减循环水泵的台数来实现调节,而单台循环水泵电机容量大,经常出现不在经济工况点运行的情况。为了节能降耗,将原循环水泵电机改为双速电机。改造投用后,不但使运行维护量少,而且节能效果明显。
With the load and season changing, circulating water of condenser only can be adjusted by number changing of the circulating pump. But single circulating pump motor capacity is great and not economic. To reduce energy consumption, the original plant circulating pump motor was changed to dual-speed motors. The conversation not only reduced operation and maintenance, and was efficient in energy-saving.
