G32型Elite集聚纺细纱机提高锭速的探讨

Discussion on Improving Spindle Speed of the Elite Compact Spinning Frame G32

为了充分发挥G32型Elite集聚纺设备优势,减少高锭速下断头,分析提高锭速前期良好的设备状态准备工作的主要内容,并借助绪森新一代胶辊可翻转技术和立达钢领对中专用工具,将精梳纯棉针织用纱品种锭速从16.7 kr/min逐步提高到20.5 kr/min的实践;对比分析不同锭速下成纱质量、千锭时断头和长期运转稳定性等的变化,强调提高锭速过程中在提速步骤、钢丝圈质(重)量选择及钢领磨合3方面的注意事项。指出:要实现高锭速长期稳定生产,必须科学严谨对待,选择合适的工艺设定,做好基础管理工作,合理使用专件器材,可在一定程度上提高企业投资回报率,缩短投资回收期。

In order to give full play to the equipment advantages of the Elite compact spinning frame G32,and reduce broken ends under high spindle speed,analysis is made to the main content of good equipment status for improving spindle speed of preparatory work in the early,and practice of improving spindle speed of combed cotton knitting yarn from 16.7 kr/min to 20.5 kr/min gradually is made with the help of the new Suessen cot turnover technology and Rieter special tool for ring centring.The changes such as yarn quality,broken ends per thousand spindles and long-term running stability at different spindle speeds are compared and analyzed,and matters need attention in the steps of speeding up,the choice of traveller weight and spindle running-in in the process of improving spindle speed are emphasized.It is pointed out that in order to achieve long-term stable production with high spindle speed,we must be scientific and rigorous,choose the appropriate process setting,do a good job in basic management,use special parts and accessories reasonably,which can improve the enterprise’s return on investment to some extent,and shorten the investment recovery time.
