摘　　要：循环水泵是循环冷却水系统的重要设备之一,该设备正常运行与否直接关系到机组安全运行。在循环水泵定期切换工作中,由于循环水泵出口蝶阀运行状态不正常,容易发生故障停机情况,从运行和检修两方面把关,切实保证了循环水泵及机组稳定可靠运行。The circulating water pump is one of the important equipment of the circulating cooling water system.The normal operation of the equipment is directly related to the safe operation of the unit.In the regular switching work of circulating water pump,due to the abnormal state of butterfly valve at the outlet of circulating water pump,it is easy to cause the loss of circulating water and the occurrence of fault shutdown.The stable and reliable operation of circulating water pump is guaranteed and the safe operation of the unit is guaranteed by the two aspects of operation and maintenance.

关 键 词：循环水泵 定期工作 出口蝶阀 电流
