The tribological interface characteristics of cotton and ramee braided soft sealing packing in dynamic sealing of high pressure and high water-based fluid were analysed, and the effect of frictional load, surface roughness and velocity on its frictional coefficient was studied by Ring and Block Friction Tester. 分析了高压高水基棉麻动密封软填料的摩擦界面形态,采用环块试验机研究了载荷、表面粗糙度和转速对其摩擦因素的影响。
The graphite molded packing, the asbestos thread PTFE-greased braided packing and the carbon-fibre braided packing were tested and the coefficients of a cycle ring were experimentally determined. 以膨胀石墨模压成型填料、石棉线浸渍聚四氟乙烯编织填料和碳素纤维编织填料为试验样品,实验确定了单圈填料的侧压系数。
