Abstract

PURPOSE:To prevent the corrosion of a pump and the like by injecting demineralized water of high content of dissolved oxygen and holding the quantity of the demineralized water constant when the detecting value of the dissolved oxygen in an internal pump system is prescribed value or less. CONSTITUTION:A part of circulating water of takeoff piping 5 of an internal pump 4 is introduced in a dissolved oxygen system and the quantity of dissolved oxygen is detected. When dissolved oxygen is prescribed value (0.1ppm) or less, the demineralized water of high content of the dissolved oxygen in a dissolved oxygen regulating tank 9 is regulated by a control valve 10, transferred to an injection pump 7, mixed with the demineralized water in a bypass pipe 11, comes at the suction side of the injection pump 7 and injected into a circulating piping 4 through a return piping 8. The part corresponding to increased flow is returned to the tank 9 through a make-up water pipe 14 and a control valve 18. The supply is performed into the tank 9 through piping 16 and the injection pump 7.
