摘　　要：针对传统填料密封损耗大、寿命短、易泄露等缺点,介绍一种新型密封填料(塑性纳米密封填料)。新密封填料为层状剪切物,其机体具有可塑性。在其内部定向排列的大量纳米纤维使得它的塑性工作面在微观上产生密集的凸凹起伏,形成无数的近似纳米级凹坑以聚集微型水珠。在实际运行中,该填料在压力水的作用下与旋转轴动态配合面形成连续的液膜,这起到了优秀的润滑和密封作用。通过在水泵上的应用和研究,结果证明:新型塑性纳米密封填料的应用是提高密封填料的密封性能、使用寿命和节能高效的一条有效途径。The traditional packing seal is big loss,short lift,easy leak, Introduced a new seal packing（ plastic nano seal pack- ing）. New seal packing is laminar shear, in which is a plasticity. In its internal alignment of a large number of nano-fiber makes it plastic face to produce dense punch undulation, the formation of numerous approximation nano scale pits to gather micro-drops of water. In the actual operation, the filler under the action of water in the pressure with the dynamic mating face of the rotation shaft to form a continuous liquid film, that plays excellent lubrication and sealing. Through the application and research of pump. the result prove ： the application of new plastic nano seal packing is an effective way to improve the seal packing seal performance, service life and energy-efficient.
