DEVICE FOR CONTROLLING REGENERATED FLOW RATE FOR CONSTRUCTION MACHINE AND METHOD FOR CONTROLLING SAME |
摘要 |
Disclosed are a device for controlling a regenerated flow rate for a construction machine and a method for controlling the same, the device being able to supply a large chamber of an arm cylinder with a part of operating oil, which is discharged from the arm cylinder to an operating oil tank during arm-in driving, and regenerating the same. The present invention provides a device for controlling a regenerated flow rate for a construction machine, the device being characterized by comprising: a variable capacity-type hydraulic pump and a pilot pump; an arm cylinder driven by operating oil supplied from the hydraulic pump; a variable arm regeneration valve installed in a passage between the arm cylinder and the operating oil tank; and an electronic proportional valve installed in a passage between the pilot pump and the arm regeneration valve. |
