喷气织机引纬工艺参数的最佳选择

Optimum selection of weft insertion parameters of a air jet loom

本文讨论了喷气织机喷嘴的喷气时间、供气压力、主喷嘴喷气的开始时间及主喷嘴和储纬器微风等引纬工艺参数对纬纱飞行的影响．通过观察纬纱的飞行状态及其到达右侧布边时间，提出了能使织机顺利生产的最佳供气压力和喷气时间，这比喷气织机说明书设定的供气压力和喷气时间小，减少了耗气量。

This paper discusses the influence of some weft insertion parameters which includes the nozzles jetting period,the air supply pressure,the initial jetting time of the main nozzle,the breeze of the main nozzle and the pick storer on the weft insertion movement. According to the weft flying performance and the weft arrival time on its destination, we can get the optimum air supply pressure and the jetting time which can maintain the loom production smoothly, these parameters are less than that selected by the manual and decrease the air consumption.
