&nbsp; 因此,引纬系统是喷气织机的关键之一。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%;

overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp; &nbsp; 早期的喷气织机引纬系统,是用一种多孔喷管直接向梭口中喷射气流进行引纬。这种引纬方式气流扩散严重,气流速度在梭道中下降很快,梭道出口侧的气流紊乱,不能有效地牵引纬纱,引纬的有效长度不足1m,纬缩和缺纬等织疵难以避免,而且引纬所需要的气压较高,动力消耗大。</p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

&nbsp; 为了改变上述的气流状态,研究和发展了管道喷气引纬。管道片有效地减少了气流的扩散,提高了梭道出口侧的气流速度,为顺利引纬提供了有利的条件。管道片引纬显著地提高了布面质量,并使引纬有效长度达到1m以上,引纬需要的气压降低,动力消耗亦减少。因此管道片引纬的应用,使喷气织机可以用来装备生产车间,成为最早商品化的喷气织机(图2-2)。</p><p style="max-inline-size: 100%;
