| Abstract: | The principle and workflow of the water-surround-vacuum pump is introduced in detail, and in connection with the Inner Mongolian Menghua Haibowan Power Plant switching the water-surround-pump regularly, shut-down accident is caused by the entry electronic-valve fault. The accident conscientiously is researched and analyzed. It is discovered the design problem of the water-surround-vacuum pump system. The technical transformation is implemented to install the non-return valve in the pump entry pipeline, and long-term test is carried on. The result has shown that the vacuum-drop and shut-down accident of switching the water-surround-vacuum pump has been solved successfully. |
