PUMP SYSTEM AND DRAINAGE PUMPING STATION
PROBLEM TO BE SOLVED: To provide a pump system that is build while taking into consideration of an event that a pump room is flooded, and to provide a drainage pumping station.SOLUTION: A pump system includes: a vertical shaft pump for guiding water from a suction water sump to a discharge water sump; and a control device for controlling a performance curve of the vertical shaft pump or a pipe line resistance curve based on a water level difference between the suction water sump and the discharge water sump so that an operation point defined in accordance with the performance curve and the pipe line resistance curve falls within a prescribed range.SELECTED DRAWING: Figure 1
【課題】ポンプ室が浸水した場合も考慮したポンプシステムおよび排水機場を提供する。【解決手段】吸込水槽の水を吐出水槽に導く立軸ポンプと、前記立軸ポンプの性能曲線と、管路抵抗曲線と、に応じて定まる運転点が所定範囲内となるよう、前記吸込水槽と前記吐出水槽の水位差に基づいて前記性能曲線または前記管路抵抗曲線を制御する制御装置と、を備えるポンプシステムが提供される。【選択図】図１
