DRAINING SYSTEM
PROBLEM TO BE SOLVED: To reduce a cost of a maintenance work.SOLUTION: A water intake part 12 performs water seal of an upstream side tip of a water pipe 11 arranged in a water storage tank 91-1. A water draining part 13 performs water seal of a downstream side tip of the water pipe 11 arranged in a water storage tank 91-2. A feed water tank 14 feeds water to the water pipe 11. A vacuum pump 17 sucks air existing in the feed water tank 14. A water level sensor 16 measures a water level in the water storage tank 91-1 and a water level in the feed water tank 14. A control part 18 starts an operation of the vacuum pump 17 when the water level in the water storage tank 91-1 exceeds suction-permitting water level H1 and the water level in the feed water tank 14 falls short of an operation water level H5, and performs a control for stopping the operation of the vacuum pump 17 when the water level in the water storage tank 91-1 falls short of a suction-inhibiting water level H3 or when the water level in the feed water tank 14 exceeds a stopping water level H4.SELECTED DRAWING: Figure 5
【課題】保守作業のコストを低減する。【解決手段】取水部12は貯水槽91−1内に配置される送水管11の上流側先端を水封する。排水部13は貯水槽91−2内に配置される送水管11の下流側先端を水封する。給水タンク14は送水管11に水を供給する。真空ポンプ17は給水タンク14内に存在する空気を吸引する。水位センサ16は貯水槽91−1内の水位および給水タンク14内の水位を計測する。制御部18は、貯水槽91−1内の水位が吸引可能水位H1を上回っており、かつ、給水タンク14内の水位が運転水位H5を下回ったときに真空ポンプ17の運転を開始し、貯水槽91−1内の水位が吸引禁止水位H3を下回ったとき、または、給水タンク14内の水位が停止水位H4を上回ったときに真空ポンプ17の運転を停止する制御を行う。【選択図】図5
