中文摘要：
为分析供气压力对辅助喷嘴气流中心线的影响,以避免出现虚假汇交现象,首先对主辅喷射气流产生虚假汇交现象进行理论分析,在此基础上利用气体流场测试装置,以泰坦TT-800喷气织机为实验平台,在改变供气压力条件下,对津田驹HTS1-9D的D型辅助喷嘴的实际流束中心线进行了测试分析。结果表明,当辅助喷嘴供气压力增大时,到达筘槽内侧的辅助喷嘴实际气流中心线与辅助喷嘴几何中心线之间的垂直距离逐渐增加。在实际织造生产中,可根据到达筘槽内侧的辅助喷嘴实际气流中心线与辅助喷嘴几何中心线之间的垂直距离的变化,来适当调节辅助喷嘴的安装高度,以避免出现虚假汇交现象,提高织造效率。
英文摘要：
In order to avoid happening of the false intersection phenomenon,it is necessary to analyze the influence of the supply gas pressure on the air flow centerline of assistant nozzle.This paper carries out theoretical analysis of the reason leading to false intersection phenomenon of two sets of airflow jetting from the assistant nozzle and the main nozzle.Then taking Taitan TT-800 air jet loom as a test platform,the actual flow beam centerline of the Tsudakoma model HTS1-9D assistant nozzle was tested through changing the supply gas pressure.It was found by analysis that increasing the supply gas pressure,the distance from the center of the assistant nozzle to the central air jet in the inside reed canal is increased.Therefore,in practical weaving,we can adjust the installation height of the assistant nozzles to avoid ″false intersection″ phenomenon,and improve weaving efficiency according to the change of the distance from the center of the assistant nozzle to the central air jet in the inside reed canal.
