循环冷却水系统长时间运行,水份不断蒸发,含盐浓度逐渐浓缩,造成硬度变大;循环冷却水的水温和pH值等又适宜多数微生物的生长和繁殖,结果导致大量的粘泥沉积在金属表面上;为确保系统正常运行,需要对循环冷却水进行加药处理,同时,对加药系统原理、水质检测参数选择、加药设备配置等情况也进行了介绍。
Circulating cooling water system running for a long time, the water evaporates continuously, the salt concentration is gradually concentrated, resulting in hardness increases; circulating cooling water temperature and pH values and most suitable for the growth and reproduction of microorganisms, resulting in a large number of sludge deposition Metal surface; in order to ensure the normal operation of the system, the need for circulating cooling water dosing treatment, at the same time, the dosing system principle, water quality testing parameters selection, dosing equipment configuration, etc. are also introduced.
