| description | The present invention relates to a hydraulic system of a construction machine and a control method thereof. The hydraulic system of a construction machine includes: a plurality of pressure controlling hydraulic pumps which are driven by an engine arranged in the construction machine; an actuator which is driven by a driving fluid discharged from the hydraulic pumps; a closed center type main control valve which is arranged between the hydraulic pumps and the actuator and bypasses a supposed amount of the fluid; and a control unit which receives the supposed amount of the fluid bypassed through the main control valve to control the hydraulic pumps. |
