ABSTRACT:
A hydraulic drive system that does not cause a decrease in efficiency of actuators, does not hinder an optimal action of devices such as flow adjustment valves, and does not cause any corrosion of water acting as an operating fluid. The system uses water as an operating fluid. The system includes a hydraulic generation apparatus40including, a main tank41, a return path52, an accessory tank54, and a water disposal apparatus56disposed in a path57. The operating fluid from structuring devices of the processing apparatuses10, 20and30flows through the return path52. The operating fluid flows from the accessory tank54to the main tank41through the path57and the water disposal apparatus56.
