复卷机纸辊振动案例浅析

Analysis on the Case of Paper Roll Vibration of the Rewinder

复卷机仅针对控制系统进行了升级。纸机由新闻纸改产文化纸后,复卷纸辊出现振动问题,车速无法运行到正常车速,被迫降速维持。针对振动这个复杂问题,从程序优化、现场设备、电气控制、液压控制等可能引起振动的各个方面进行了排查、优化、处理,最终实现了复卷机正常车速平稳运行。对各方面检查的步骤、参数、曲线等进行了详细地阐述。

The rewinder is only upgraded for the control system.After the paper machine being transferred from producing newsprint to printing and writing paper,the rewinding paper roller showed vibration problems.And it could no longer work at its designed speed,but was forced to slow down.In order to solve this problem,various aspects of vibration,such as program optimization,field equipment,electrical control,hydraulic control,etc.,have been investigated,optimized,and processed,and finally the rewinder resumed normal operation.The steps,parameters and curves of all aspects of the inspection are described here in this paper.
