摘　　要：敞开式循环冷却水系统正常运行期间,一般pH值在8.0~9.0之间,偏碱性。当工艺系统换热器设备出现泄漏时,大量介质被带入循环水中,引起循环水pH降低,此时循环水系统腐蚀性大大增强,应及时采取有效措施予以遏制。Open cycle cooling water system during normal operation,general pH value between 8—9,alkaline.When a process system of heat exchanger leakage,a large number of medium were brought into the circulating water circulating water,caused by reduced pH,the corrosion of circulating water system is strengthened greatly,should take effective measures in time to prevent.
