Method for judging accuracy of pH value of internal cooling water of generator

The invention discloses a method for judging the accuracy of pH of internal cooling water of a generator, and belongs to the field of internal cooling water treatment of generators. And whether air enters the internal cooling water system or not is judged according to the internal cooling water hydrogen conductivity data. When air does not enter the internal cooling water and the pH online instrument measurement value is in the range of 7-9, the analysis value of the pH uses an online formula pH = 8.57 + lgSC; when air enters the internal cooling water and the pH online instrument measurement value is in the range of 7-9, the analysis value of the pH is equal to 8.57 + 1g (SC-CC/3) by using an online formula; in other states, the pH analysis value is equal to the real-time data of the online pH instrument. In the running process of the internal cooling water, no matter whether air enters an internal cooling water system or not, accurate judgment of the pH of the internal cooling water can ...
