PAT系列喷气织机引纬工艺设定及故障分析

摘要

Weft insertion processing settings and faults analyses of PAT series air-jet loom were summed up. Through analyzing structure and property of PAT series air-jet loom, it is considered that starting time of weft insertion is set in 70° - 90°generally, main jet pressure is lower 0.05 Mpa ~0. 1 Mpa than that of auxiliary jet pressure generally. For left yarn cutting time setting,PAT-NU loom is 12° ~ 18°generally ,PAT-A loom is 8° - 12°generally. Defects of weft kinks,weft broken ends can be reduced efficiently,pruduct quality can be improved and loom efficiency can be ensured through setting weft detection time,maintaining and checking weft insertion system.%总结PAT型喷气织机引纬系统的工艺设定及常见故障的解决措施.通过分析PAT型喷气织机引纬系统的结构和特点,认为:引纬开始时间一般设定在70°～90°；主喷气压一般应低于辅喷气压0.05 MPa ～0.1 MPa；左侧剪纱时间的设定,PAT-NU型织机一般在12°～18°,PAT-A型织机一般在8°～12°；合理设定探纬时间等工艺参数,同时做好引纬系统的维护和检查工作,能有效减少纬缩、断纬等疵点,提高产品质量,保证织机效率.
