Abstract

건설장비의 펌프제어 작동시스템이 개시된다. 개시된 발명은 굴삭기와 같이 유압으로 구동되는 다수의 액추에이터들을 구비하는 건설장비에 있어서, 상기 엑추에이터들 중 일부의 액추에이터는 그 각각에 유압펌프가 연결되어 각각의 펌프로부터 유량을 공급받는 1:1 펌프 시스템(A)에 포함되고, 나머지 액추에이터는 하나 이상의 펌프에 연결된 보조 컨트롤 밸브(120)에 의해 유량을 분배받는 보조 컨트롤 밸브 시스템(B)에 포함되며, 상기 보조 컨트롤 밸브(120)에 연계된 액츄에이터의 유량이 부족한 경우, 상기 보조 컨트롤 밸브(120)에 연계된 액츄에이터는 1:1 펌프 시스템(A)의 펌프를 공유하도록 1:1 펌프 시스템(A)의 펌프에 연결되는 것을 특징으로 하여 구성됨으로써 보조 컨트롤 밸브에서 발생되는 유량부족을 1:1 펌프시스템의 펌프로부터 보충하여 보조 컨트롤 밸브에 의해 작동되는 액츄에이터의 원활한 작동을 제공할 수 있다.
