摘　　要：海水循环泵的腐蚀与防护对滨海发电厂的安全发电至关重要 ,近些年来滨海电厂主循环泵的防护已普遍应用了阴极保护技术。以某发电厂 30 0MW机组配置的型号为 6 4TKXE 15海水循环水泵为例 ,对其外加电流阴极保护技术应用中阴极保护系统失效原因及存在的问题进行了探讨及总结 ,并给出了具体的防范措施。Corrosion and protection of seawater circulating pump are important for safe power generation in coastal power plant. In recent years, cathodic protection technology has been commonly used for protecting the main circulating pump in coastal power plants. Taking 64TKXE15 type seawater circuilating pump used for 300MW unit in one power plant as example, analysis of failure for cathodic protection system in application of impressed current cathodic protection (ICCP) for seawater circulating pump and existing problems have been discussed and summarized, and concrete preventive measures being given.
