| description | A hydraulic system for increasing a speed of a boom of a construction machine includes a boom cylinder configured to operate the boom of the construction machine; a main control valve including a boom control spool that is configured to selectively supply a hydraulic oil from a hydraulic pump to a boom head chamber and a boom rod chamber of the boom cylinder; a regeneration device connected to the boom head chamber of the boom cylinder through a hydraulic regeneration line and configured to regenerate an energy of the boom cylinder; and a regeneration valve unit provided at the hydraulic regeneration line and including a flow control valve configured to control a flow rate of a hydraulic oil flowing through the hydraulic regeneration line. An energy stored in the regeneration device is directly supplied to the boom cylinder through the flow control valve when the boom ascends. |
