管道片式喷气织机引纬管道内气流速度分析

A Study on Air Flow Velocity in Constrictors System of an Air-jet Loom

本文以管道片式喷气织机的引纬管道为研究对象。假设气流在该引纬管道内,每一个管道片单元内的流动是由管内流动和射流两部分组成。对整个引纬管道内的流动进行迭加综合,得出在整个管道内气流速度的衰减规律计算公式为其结论是:气流在引纬管道内的速度衰减变化主要与管道片的组合结构有关,而与气流速度无关。

Taking the constrictors system of an air—jet loom as an objelt, Surposing the air flow in the constrictors system is composed with two parts, the flowing in a pipe and air jetting, this paper analysis the prieiple of air flow movent in the constrictors system, is composed with two parts, the flowing in a pipe and air—jetting, this paper analysis the princple of air flow movement in the costrictors system and gets the air veloity calculating for mula is
