（1）流体在喷吹管上诸喷嘴口处应实现等压、等量喷吹脉冲阀的喷吹流量是以高速度进入喷吹管内的，流体主要靠静压力从喷嘴喷出进入滤袋。在接近喷吹管进口处时流体的动压O、静压O小，在喷吹管底部流体的动压降为零，静压达到O值。调整喷吹管上喷嘴孔径的大小，可实现在不同阻力下，使流体通过诸喷嘴时的静压力相等，也就可以保证除尘滤袋的清灰效果一致，滤袋使用寿命相同。

在喷吹管上喷嘴的处理方面，现在大多数的除尘设备制造厂家基本都是采用等孔结构，由于流体在诸喷嘴口的喷吹压力是不相同的，因而滤袋受到的冲击力差异很大，这样就会导致一些滤袋负荷过大，从而缩短了寿命。还有一些除尘设备厂虽是采用喷嘴孔径逐减的方法，但也很难保证诸喷嘴口在喷吹时的喷嘴压力是相等的。
