超级回潮机加水精度控制分析及应用

烟草制丝工艺过程中,承担增湿增温功能的超级回潮机加水系统应用气动薄膜调节阀控制,机械故障率较高,导致超级回潮机出口处烟叶丝含水率不均匀、不稳定,甚至有湿团烟的状况。采用变频水分控制方式和增加PID水分偏差运算控制,提高水分控制精度,降低了运算误差,而且避免加水系统的机械故障。

Super Resurgence Machine Precision Control of Water Analysis and Application

In the process of the tobacco silk process,the super resurgence machine which add temperature and humidity,applies pneumatic film regulator that control the water flowing.The pneumatic film regulator's mechanical failure rate is higher that result in outlet containing water which is not uniform,not stable,or even wet group.With frequency conversion water control mode and the add PID deviation operation control mode,improves water control accuracy,reduces the computational error;And avoid the adding water sy...
