摘　　要：针对集聚赛络纺纱系统能耗较大的问题,设计3种导流装置,以降低集聚赛络纺纱系统的负压,达到节能降耗的效果。首先通过solidworks软件建立集聚赛络纺纱集聚区三维物理模型,利用fluent进行数值模拟,分析集聚区气流场的分布情况;然后通过纺纱实验进一步验证导流装置能够起到节能降耗的效果。结果表明:出口负压越大,集聚槽附近的速度越大,集聚槽上方的气流对须条起到挤压作用,使须条紧紧贴在网格圈表面,集聚槽侧向气流使须条宽度减小,须条表面的毛羽能够卷入到纱体表面,形成紧密的结构,从而能够减小甚至消除加捻三角区;使用所设计的3种导流装置(集聚负压1000 Pa)纺制出来的纱线与普通集聚赛络纱(集聚负压2000 Pa)质量相当,甚至更好。In view of the large energy consumption of the compact siro spinning system,three kinds of diversion devices were designed to reduce the negative pressure of the compact siro spinning system and achieve the effect of energy saving and consumption reduction.Firstly,a three-dimensional physical model of the compact siro spinning agglomeration area was established by solidworks,and the distribution of the airflow field in the agglomeration area was analyzed by numerical simulation using Fluent.Secondly,the spinning experiment further verifies that the diversion device can save energy and reduce consumption.The accelerated air flow from the top of the agglomeration tank to the agglomeration tube adsorbs the fiber,and the accelerated airflow on both sides of the fiber whisker on the agglomeration tank reduces the width of the twisted triangle.The diversion device can reduce the negative pressure of agglomeration required for normal spinning,and the effect of the diversion component I is better;when the negative pressure of agglomeration is as low as 1000 Pa,the quality of the spined yarn is comparable or even better when the negative pressure of agglomeration is 2000 Pa.
