摘要
为进一步降低喷气织机能耗,设计了3种不同孔径的辅助喷嘴,运用流体动力学分析模块对辅助喷嘴引纬流场进行仿真模拟,得到不同孔径下辅助喷嘴出口射流中心线的速度分布曲线。采用自主设计的实验平台获取射流中心线的速度分布,并与模拟的速度结果进行比较。对比结果证明,采用仿真模拟分析辅喷流场的准确性,可为优化辅助喷嘴结构参数,降低织机能耗提供理论参考。结果表明:供气压力为0.3 MPa时,直径为1.1 mm的辅助喷嘴能耗比直径为1.5 mm的辅助喷嘴降低了约25%。
In order to reduce the energy consumption of the air jet loom,three different pore sizes of the auxiliary nozzle were designed. Fluid dynamics analysis module was used to simulate the weft insertion flow filed of auxiliary nozzle. The velocity distribution curve on the central line of different pore sizes of auxiliary nozzle was obtained. A designed experimental platform was used to testify the theory values. It is found that flow field simulation analysis is in accordance with experimental value. The theory can be used to improve the structure and reduce energy consumption of the auxiliary nozzle. The experimental results showed that when the supply gas pressure was 0. 3 MPa,the pore size of nozzle was 1. 1 mm,and the energy consumption was reduced by about 25 % compared with that of the pore size of 1. 5 mm.
