System Functions
Profile the difference of the CD basis weight automatically, improve the sheet’s CD basis weight
Fast and accurate adaptive CD basis weight control
Self-diagnostics of the actuator’s mechanical and electrical condition with detailed alarm displays for operators
Integration into software allows easy operation, maintenance and tuning
Interface access with a serial to QCS or DCS
Steam and Condensate System
The adjustable thermocompressor is equipped with self-regulated device which can change the nozzle opening automatically on different working conditions to accommodate the steam flow for steam saving and dryers drainage. Comparing to the ordinary thermocompressor, it is adaptable and more efficient and also can improve machine speed, increase production, reduce energy consumption and optimize the machine operation.
Distributed Control System (DCS)
Control part adopts Siemens PLC, combined with network technology and Shuangyuan automatic control technology.
The advantages of Shuangyuan DCS system
