MANHOLE PUMP SYSTEM, MANHOLE PUMP CONTROL DEVICE AND MANHOLE PUMP CONTROL METHOD
To provide a manhole pump system that has a low load of restoring a pump and that can suppress occurrence of noise more than when using an engine type pump.SOLUTION: A manhole pump system comprises pumps 23a and 23b for sucking and discharging liquid inside a storage tank, power supply passages R1-1, R0, R0a and R0b for supplying commercial power to the pumps 23a and 23b, power supply passages R2-1, R0, R0a and R0b for supplying second electrical power to the pumps 23a and 23b from a portable type storage battery 61 arranged outside the storage tank, an inverter 311 for converting a characteristic of commercial power in matching with a characteristic of storage power, a change-over switch 33 that switches the power supply passage R1-1, R0, R0a and R0b to the power supply passage R2-1, R0, R0a and R0b and that supplies one of commercial power and converted storage power to the pumps 23a and 23b, and an inverter 312 with a soft start function of suppressing a start current of the pumps 23a and 23b to which commercial power or converted storage power is supplied.SELECTED DRAWING: Figure 4
【課題】ポンプの復旧に係る負荷が小さく、また、エンジン式のポンプを使うよりも騒音の発生を抑止できるマンホールポンプシステムを提供する。【解決手段】貯留槽の内部の液体の吸い込み及び吐出を行うポンプ２３ａ、２３ｂ、ポンプ２３ａ、２３ｂに商用電力を供給する電力供給路Ｒ１－１、Ｒ０、Ｒ０ａ、Ｒ０ｂ、貯留槽の外部に配置される可搬式の蓄電池６１からポンプ２３ａ、２３ｂに第二の電力を供給する電力供給路Ｒ２－１、Ｒ０、Ｒ０ａ、Ｒ０ｂ、商用電力の特性を蓄電電力の特性に合わせて変換するインバータ３１１、電力供給路Ｒ１－１、Ｒ０，Ｒ０ａ、Ｒ０ｂと、電力供給路Ｒ２－１、Ｒ０、Ｒ０ａ、Ｒ０ｂと、を切り替えて、商用電力、または変換された蓄電電力の一方をポンプ２３ａ、２３ｂに供給する切替スイッチ３３と、商用電力、または変換された蓄電電力が供給されるポンプ２３ａ、２３ｂの始動電流を抑止するソフトスタート機能付インバータ３１２と、によりマンホールポンプシステムを構成する。【選択図】図４
