Working principle: Transport goods in sealed tube by the power of compressing and pumping air.

工作原理：以空气压缩机抽取及压缩空气为动力，在密封的网管中自动传送物品。

A compact pumping station pumps the water via a two-stage filter to special nozzles where it nebulises under high pressure in aerosol mist and is mixed with air by means of turbulence elements.

紧凑型泵站把水流通过双层过滤器抽吸到特定的喷嘴处，在高压作用下形成水雾状，并以湍流原理方式与空气结合，由于这种雾化作用和深度空气混合，使得越来越多的雾化水蒸发。

The stability of the interface between two-layer fiber flow is essential for getting high quality multi-formation and layer purity. Some measures of keeping the stability of interface are got from theoretical analyse. The measures is close reducing the velocity difference between two layers; putting the fiber of lower density on the upper layer and the fiber of relatively higher density on the lower layer; and using low pulsation pump as the pumping equipment.

两层叠加流动的界面稳定性对多层成形的质量及层间纯度有重要影响，本文通过采用小扰动法对流动界面的稳定性分析认为，减小层间速度差；把密度较大的纸浆置于下层，密度较小的纸浆置于上层；以及采用低脉冲泵作为上浆泵均有利于保持层间流动界面的稳定性。
