Design and Application of Hydraulic Control System for Swimming Roller in Paper Machine Press
Based on the problems existing in the old swimming roller control system,a complete set of hydraulic control for the swimming roller is designed in this paper,combined with the methods and debugging experience of hydraulic control system design accumulated by the author in many years of engineering.The PID control function in the PLC control system is used to achieve closed-loop control of line pressure and controllable closed-loop control of medium and high line pressure through the proportional valve,as well as key parts such as synchronous control of the operation and transmission sides of the swimming roller.
