摘要
本文主要论述了当前国内造纸机传动控制系统中稳速环节的改进,及改进后运行状态.实践证明,改进后的稳速精度可以同进口同类设备的稳速系统相比.开机2h后测8h内速度漂移≤2‰,已达到国内摸拟控制系统最高水平.
The article is dwelling on the improvement of the link of speed -stable in drive system and the drive state after the improvement. The precision can be up to the level of foreign advanced speed-stable system. The eight-hour speed fluctuation ≤2% after starting-up 2 hours. It is up to the highest level in analogue control systems in China.
