发电机组海水冷却系统的腐蚀与防护

Corrosion and Protection of Seawater Cooling System of Power Units

摘要: 总结了海水冷却系统的组成和主要材质。认为对海水冷却系统进行全面保护，首先是选好材；其次是做好涂层或内衬等表面处理和阴极保护。对于海水循环冷却系统，还要做好海水循环冷却塔的防腐和整个海水循环冷却系统的杀生处理。另外是做好胶球清洗等工作，保持冷却水系统清洁，特别是凝汽器管内表面干净。

Abstract: Composition and main material of seawater cooling systems of power units are stated briefly. Some corrosion and protection examples of seawater cooling systems are summarized. In order to protect totally seawater cooling system, the right material should be chosen, and surface treatment such as coating or lining and cathodic protection should be done well. In order to protect seawater cycling cooling system, beyond that, protection of the seawater cycling cooling tower and biocide treatment of the seawater cycling cooling system should be done well, too. In addition, rubber ball cleaning should be done well; the seawater cycling cooling system, especially the inner surface of condenser tubes should be kept clean.
