摘　　要：探讨FA425A型粗纱机几个重要参数的设定及调整方法。分析介绍了粗纱捻系数和牵伸隔距以及牵伸分配、锭速、主机加速和减速时间参数、与粗纱纺纱张力相关参数、粗纱卷装的轴向卷绕密度和外形尺寸以及卷装换向位置等参数的设置和调整方法。认为:设置相关参数时应以计算值为基准,充分考虑所纺品种、粗纱定量、粗纱捻系数、锭速、锭翼压掌绕扣数、车间温湿度等因素的影响,具体可根据实际情况进行调整;掌握其调整方法,有利于充分发挥FA425A型粗纱机的性能。Several important parameter selection and adjustment methods of FA425A roving machine were discussed. A series of parameter selection and adjustment methods were introduced and analyzed,including roving twist fac- tor,draft gauge and draft distribution, spindle speed, main engine acceleration and deceleration time parameter, roving tension related parameter, roving package axial winding density and external size, package commutation position et al. It is considered that calculated value should be selected as datum in setting related parameter,effect should be considered fully including yarn, roving weight per unit, roving twist factor, spindle speed, flyer press number, temperature and humid- ity of workshop. The parameter should be adjusted according to actual situation. Property of FA425A roving machine can be used fully through selecting ajdustment method rationally.
