| Abstract: | The outlet valve lever of motor driven feedwater pump had frequent failures during its operation. Based on the principle of electrochemical corrosion, an analysis is made on the cause of corrosion of the valve lever at feed water pump outlet in one power plant, while preventive measures and solutions are put forward, which can be used as references for the metal supervision of power plant. |
