发明名称 Draining pump system and drainage preference operating method therefor
摘要 When any component equipment of a draining pump plant is failed, the present necessity of drainage and a failure level of a drain pump involved with the failure are evaluated to determine conditions of continuing or stopping operation of the drain pump involved with the failure on the basis of the evaluated values. When the necessity of continuing the drainage operation is high, the operation is continued as far as possible, taking into account the pump failure level. The possibility of the drainage preference operation is thus maximized in the case of not only a minor failure but also a major failure of the pump, for preventing damage from a flood.
