摘　　要：对于将未加氨的微酸含氧的除盐水作为发电机内冷水补充水时,相对于pH值为7.0~8.0时,适当地调整内冷水的pH值位于8.0~9.0之间可减少铜腐蚀的速率和腐蚀程度。并且根据控制pH值范围区间计算出合理的加碱剂量,更能够保证发电机内冷水水质品质,确保发电机组安全运行。When using the slightly acidic oxygen-containing desalinated water without ammonia as the supplementary water for the cold water of the generator,relative to the pH value of 7.0-8.0,the appropriate adjustment of the PH value of the internal cold water between 8.0-9.0 can reduce The rate and extent of copper corrosion.And according to the control PH value range interval to calculate a reasonable alkali dosage.It can also ensure the quality of the cold water in the generator and ensure the safe operation of the generator set.
