HYDRAULIC PUMP FLOW CONTROL METHOD FOR CONSTRUCTION MACHINERY
굴삭기 등의 건설기계에 구비되는 유압펌프 제어시스템을 개시한다. 본 발명에 따른 건설기계의 유압펌프 제어시스템에 있어서, 하부주행체에 대해 상부프레임을 선회 가속시키거나, 주행모터 등의 관성체를 선회시키기 위하여 유압펌프로부터 초기에 유압모터로 필요한 만큼의 작동유를 공급하여 유량 손실을 줄일 수 있도록 한 건설기계의 유압펌프 제어시스템을 제공한다.
A hydraulic pump control system provided in a construction machine such as an excavator is provided. According to the hydraulic pump control system, a loss of a flow rate is reduced by initially supplying hydraulic fluid as much as necessary from a hydraulic pump to a hydraulic motor in order to accelerate a swing movement of an upper frame against a lower traveling structure or to make an upper swing structure swing.
