부스터펌프제어시스템에관한것이다.
배경기술
[2] 아파트를포함한다중이용시설건물의급수를위해서는하나이상의
급수펌프를사용하는데，정해진급수펌프를완전가동시키는직입기동으로는 원하는급수량을정확하게맞추지못하고고압력으로인한배관손상때문에 인버터를이용한인버터기동을이용하여원하는급수량을공급하게하는방법을 사용한다.상기와같은것으로는하나의펌프에하나의인버터를연결하여 복수개의인버터를운용하는급수펌프제어시스템이있다.그러나
종래기술에서는제어인버터가고장나면펌프부의모든펌프가직입기동으로 작동되어야하는데，이렇게될경우원하는급수량을정확히맞추지못하고 고압력으로인해배관을손상시켜급수설비의고장을발생시킬우려가있고 원활한급수에도차질이생기게되는문제점이발생되게된다.
[3] 상기와같은문제점등을해결하고자본출원인은등록특허제
10-1306166호에서동력구분시스템과중앙제어부를포함하고,
동력구분시스템을하나이상설치하는급수펌프의동력구분및제어시스템을 개시한바있다.
[4] 그러나상기특허에서는동력구분시스템을하나이상설치해야하고，주전원의 고장시대체할방법을개시하지는못하였다.
[5] 본출원과관련하여관련분야의선행기술들을살펴보면，상기본출원인
명의의등록특허에서언급하고있는등록특허제 10-0165723호,급수장치를 공개하고있는일본국공개특허제평 8-284872,급수장치를개시하고있는 등록특허제 10-016523호，가압급수시스템의비상운전제어방법을개시하고 있는등록특허제 10-0458961호,급수시스템에서펌프모터의자동절체방법을 개시하고있는등록특허제 10-0697052호，급수장치를공개하고있는일본국 공개특허제 2012-180834호등이있으나，본출원발명이추구하는목적과그 발명사상이전혀다른발명들로판단된다.
발명의상세한설명
기술적과제 [6] 본발명은상기와같은종래기술의문제점을해결하고,하나이상의인버터를 운용하는범용의급수펌프제어시스템에서인버터제어를통한정밀한급수를 보장하고인버터제어를받지않는펌프에대해직입기동을가능하도록 구성하여요구하는수량을정확하고안정적으로급수할수있는
이중화급수펌프의제어시스템및이에사용하기적합한비상대체전원장치를 제공함에그목적이있다.
과제해결수단
[7] 본발명은상기와같은본발명의목적을달성하기위하여,하나의인버터또는 하나이상의다수의인버터를운용하는급수및부스터펌프제어시스템에서 인버터제어를통한정밀급수를보장하는제어시스템，하나이상의인버터제어를 포함하고인버터제어를받지않는펌프에대해서는하나이상의다수의 직입기동을가능하도록조합구성하여요구하는수량올정확하고안정적으로 급수할수있는제어시스템또는하나의제어시스템에동력을구분하는 제어시스템올갖고있는시스템중어느하나에있어서 ,중앙제어부가오동작시 이를대체할수있는하나이상의대체제어부를더포함하는부스터
펌프제어시스템을제공한다.상기에서하나이상의인버터를구비하여펌프를 기동시키는동력구분시스템을구비하는급수시스템에있어서，인버터의전원 그룹으로연결되며，직입기동스위치제어부와전원제어부,상기
직입기동스위치제어부와전원제어부를통하는직입기동수동조작부, 인버터제어부로구성되는직입펌프기동전원부;그리고상기
직입기동스위치제어부와인버터제어부와연결되는비상대체전원공급부로 구성되는부스터펌프제어시스템을제공할수도있다.
[8] 상기에서，비상대체전원공급장치는입력전원부로부터분기되는제 1및제 2 변압차단스위치,상기변압차단기에연결되는제 1및제 2감시스위치，상기제 1 및계 2감시스위치에연결되는차단스위치및전원공급스위치를포함함이 바람직하다.
[9] 본발명은또한，하나의인버터또는하나이상의인버터를운용하는급수
펌프제어시스템에서인버터제어를통한정밀한급수를보장하고인버터제어를 받지않는펌프에대해하나의직입기동과다수의직입기동을가능하도록조합 구성하여요구하는수량을정확하고안정적으로급수할수있는시스템에서 상기동력구분시스템은상기증앙제어부가오작동시이를대체할수있는하나 이상의대체제어부를더포함할수있고,상기동력구분시스템은상기 중앙제어부및모든대체제어부가오작동시펌프의인버터기동을보장하기 위한압력신호센서를더포함할수있으며,이중화급수펌프의제어시스템및 이에사용하기적합한비상대체전원장치를더포함할수도있다.
[10] 본발명은또한부스터펌프공급관의배관노후와공급관의이음세연결부 볼트조임불량및배관장기간사용시펌프작동층격고압력이장기간 발생하면서나타난누수로펌프실침수사고를방지하기위한
침수방지수위센서신호부와연결되는침수수위센서제어부를중앙제어부에 연결하여사용할수도있다.
[1 1 ] 즉,펌프가동량은배관내의압력이내려가면급수를더많이공급하기위해 펌프가동량을증가시키는데，배관의압력이관로의어느부분이누수로인해 압력이저하되면펌프는최대출력으로가동을하게되고누수된장소가 펌프실에서발생하면펌프실침수로이어진다.부스터펌프는펌프와 펌프사이에플렌치또는용접과볼트를사용하여조립을하는데펌프가 작동하는순간마다충격이발생하여가끔씩보수가필요하고펌프실천정과 바닥에서누수가발생하는일이많다.
[12] 펌프실은보통건물지하에있거나공장등기타장소에서도지면보다
내려가는위치에설치를한다.
[13] 따라서펌프실바닥에누수가되어물이차오르고지면바닥에서다수의물 0 수위레벨센서및볼탑의스위치또는물을감시하는신호가급수장치의 제어부에연결하여부스터시스템가동을멈추게하여관로에공급하는것을 차단하여침수를막을필요가있게된다.
발명의효과
[14] 본발명에의하면인버터를하나이상사용하는범용의급수펌프에있어서 인버터기동을담당하는인버터가고장나더라도대체인버터를통하여 인버터기동을보장받을수있으며，인버터기동을수행하는펌프의나머지 펌프를직입기동할수있어서원하는수량공급이원활하고불필요한전력을 낭비하는것을방지할수있고，비상시대체전원공급장치의사용으로항상 급수핍프의가동을용이하게하는효과가있게된다.
