摘要： PURPOSE: An energy saving type hydraulic circuit is provided to minimize energy loss by supplying working oil to a hydraulic cylinder using an electric motor. CONSTITUTION: A hydraulic cylinder(1) is installed in a flow channel of a hydraulic pump and operated with working fluid of the hydraulic pump. The hydraulic pump is driven according to the rotational direction or speed of an electric motor(10). A branch valve(3) is installed in the flow channel between the hydraulic cylinder and the hydraulic pump and converts a spool according to a control signal from the outside. A generator(16) is axis-connected in a hydraulic motor(17). The hydraulic motor is driven by the working fluid. An electronic control unit(12) drives the branch valve or the electric motor by outputting the control signal.

摘要： The present invention is to cool a cooler module using water supplied by a water circulation device. In a cooling device for construction equipment comprising an engine and a cooler module cooled by outdoor air supplied when a cooling fan connected to the engine rotates; an embodiment of the present invention of the cooling device for construction equipment comprises: a tank to store water to cool the cooler module; a pump installed in the tank and supplying water stored in the tank to the upper part of the cooler module; a hose having an inlet connected to the pump and an outlet positioned on the upper part of the cooper module; and a spraying nozzle connected to the outlet of the hose to spray the water supplied through the hose to the top of the cooler module. When the water supplied through the hose is sprayed to the top of the cooler module by the spraying nozzle connected to the outlet of the hose, the water sprayed through the spraying nozzle passes the outer wall of the cooler module and then returns to the tank by free fall.
