Abstract

Abstract PURPOSE:To rapidly raise oil temperature in a hydraulic actuation system up to a required value by providing a control system to perform heating actuation based on detected temperature. CONSTITUTION:Temperature sensors 22 and electric heaters 23 are respectively provided in an actuating part A and a servo cylinder 15, detected signals from the temperature sensors 22 are input to a controller 24, and when the oil temperature is lower than the setting value, the oil temperature is raised by heating with the electric heater 23. Consequently, the oil temperature in the hydraulic actuation system can be rapidly raised up to the required value.
