【摘要】 本文论述了ZA型喷气织机主喷嘴的结构和工作原理,主喷嘴内流道气流的结构、速度和静压特性,以及喷嘴设计上的特点等。认为,对于异形筘式喷气织机,主喷嘴的设计应以提高纬纱飞行速度为主要目标,采用两次加速,增加纬纱牵引力和动能获取量。更多还原

【Abstract】 Having analysied. the structures and working principles of main nozzel of ZA air jet loom,characteristics of air flow in internal passage of main nozzel concerning its structures, speed andstatic pressure,and contrivance of nozzels,the paper deems that increase in weft flight speed mustbe taken as basic objective of main nozzel design, namely, thatdrawing force and kinetic energy ofweft yarn are increased by two times of acceleration.更多还原
