Abstract:

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 analyis 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.
