摘要 为阐明拉瓦尔管结构对FDY型吸丝枪性能的影响,对吸丝枪流场特征进行理论分析,确定其喉部直径与喉部长度。通过改变拉瓦尔管收缩角和扩大角,测定吸丝枪的吸丝张力和压缩空气质量流率,分析收缩角α和扩大角β对吸丝枪吸丝效率的影响,得到合理的拉瓦尔管结构参数:收缩角α为90°,扩大角β为6°。结果表明:合理的收缩角有利于气流加速,并顺利形成较强的涡流,从而提高吸丝效率;合理的扩大角有利于加速拉瓦尔管扩大部位的超音速涡流,减少气流与纱线运行阻力,提高吸丝效率,但扩大角过大,会导致正激波过早出现,气流加速提前结束,动能损失大,导致吸丝效率下降。 To elucidate the effect of Laval tube structure on the performance of yarn suction gun for FDY, the throat diameter and throat length of the Laval tube are determined by theoretical analysis of the fluid field of the yarn suction gun. By changing the converging angle of Laval tube α and the diverging angle of Laval tube β, yarn suction force F and mass flow rate of compressed air G of the yarn suction gun are measured, and the effects of α and β on the yarn suction efficiency η(η= F/G) are analyzed. The optimal Laval tube is the one with geometrical parameters of α = 90° and β = 6° η can be raised through a rational α, with which the converging part of Laval tube accelerates airflow and makes the airflow develop into a strong swirling flow. A rational β contributes to not only acceleration of super-sonic swirling airflow in the diverging part of Laval tube but also low running resistance of air and yarn, thus enhances η. However, an over-large β results in a low η because it causes normal shock wave to occur early, which stops the air acceleration and leads to a great loss of kinetic energy.
