| 摘 要： | 为了探求BCF变形加工机理,利用测压探针测试了导丝管内部及出口端外的总压和静压分布规律,实验结果表明导丝管内为气流分布不均匀、速度梯度大、不对称的紊流流场。较高的进气压力,保证足够的进气量。有利于丝束的变形。

| Abstract: | In order to study the processing mechanism of BCF, the distribution of total pressure and statical pressure inside and outside the texturing tube are discussed with the help of the pressure probe, and the result of the experiments is analyzed. The result shows that the distribution of air - flow inside the texturing tube has the feature of turbulent flow, large velocity gradient, uneven and asymmetry. The conclusion is drawn and show that it is useful for the texturing of filaments with high air pressure and sufficient quantity of the air - flow. |
