Subsequently, the pressure loss of the air passage is analyzed, when none of winding units is splicing, in order to achieve the reasons of the pressure loss and suction uneven.
然后，从理论上对所有络筒单元均不进行捻接时的风道的压力损失进行分析，找出压力损失的原因以及吸风不均匀的原因。
After that, we figure out a ladder-type wind tunnel to bring out uniform suction, and provide several means to reduce the pressure loss.
根据相关理论，得出了可以实现均匀吸风的阶梯形风道，并且提出一些降低阻力损失的方法。
Compared the pressure distributions of the air passage before and after improvement, it argues that after improvement the pressure loss is decreased, and the suction is more uniform.
将其模拟结果与前面章节所得到的改进前的风道分析结果进行对比，证明改进后的风道能够有效的降低压力损失，同时使吸风相对均匀。
