Cleaning method of water cooling system

The invention relates to the field of water refrigeration. A cleaning method of a water cooling system includes the steps that firstly, high-flow water washing is conducted in forward and reverse directions, then corrosion inhibitors are added for buffering, sulfamic acids are added for acid pickling, Fe2+ and Fe3+ in the system are analyzed, if the content of Fe element is equal to or greater than 5000mg/L, the original water is replaced with new water, then the corrosion inhibitors are put again for buffering, the sulfamic acids are put again for acid pickling, when the content of Fe3+ is greater than 200mg/L and reducing agents are replenished, the reducing agents are added until the content of Fe3+ is equal to or less than 200mg/L, and finally is the original water is replaced with newwater. Through the method, the refrigeration effect can be effectively improved. 本发明涉及水制冷领域。一种水冷却系统的清洗方法，首先通过正反向大水冲洗，然后投入缓蚀剂进行缓冲，然后投入氨基磺酸进行酸洗，对系统中Fe2+和Fe3+进行分析，如果Fe元素含量大于等于5000mg/L，重新更换新水，然后再次放入缓蚀剂进行缓冲，和再次投入氨基磺酸进行酸洗，当Fe3+含量大
