FA322型并条机典型波谱图分析

Typical Wave Spectrum Analyses of FA322 Drawing Frame

分析FA322型并条机几种有代表性的波谱图。通过对凹凸罗拉、匀整差动箱、齿形带或齿形带轮、圈条部位产生机械波及死区长度设置不当、条子不经正常通道产生牵伸波的原因进行分析,总结出波谱分析的几点技巧。认为:波谱分析除采用计算法、测速法这两种常用方法外,还需结合排除推断法方能找准原因,顺利解决问题。

Several typical wave spectrum of FA322 drawing frame were analyzed. Wave spectrum causes were ana- lyzed such as embossing roller, differential leveling box, saw tooth belt or saw tooth pulley, coiler part,improper dead zone length configuration,fiber sliver in abnormal channel. Skills of analyzing wave spectrum were summed up. It is consid- ered that common methods such as calculation and velocimetry should be adopted, exclude and deduce should be com- bined to analyze.
