PURPOSE: A digital control device for a screw compressor is provided to enable a manager to easily confirm a recent operation history of a screw compressor by displaying compressed air supply pressure current consumption on a display unit. CONSTITUTION: A digital control device for a screw compressor comprises a motor drive unit(200), a valve drive unit(300), a control unit(400), and a display unit(500). The motor drive unit presses air and oil and discharges compressed air without oil. The motor drive unit drives a motor for powering female and male screws. The valve drive unit drives a valve installed in a flow path. The control unit transmits a control signal to the motor and valve drive units. The display unit displays the state and information of a screw compressor. The display unit displays compressed air supply pressure, a change in discharged air temperature, and current consumption. |
