摘　　要：在DT-100多通试验台对名义过滤精度5μm的不锈钢滤芯进行性能测试。结果表明:该实验滤芯的纳污容量为5.01g,滤芯流动阻力与注入污染物质量成指数关系γ=2.523 3e^(0.7566x),过滤比随压降的增加基本保持不变,过滤比与颗粒直径的数值拟合关系为β=0.0229x^(3.8838),颗粒直径超过最大孔径,过滤比趋近无穷,该名义过滤精度5μm的不锈钢滤芯对大于5μm的颗粒过滤比为11.87,过滤效率91.58%,实际名义过滤直径为8.04μm。Filtering properties of multi-layers folded Stainless filter elements was measured at DT-100 multi-pass test stand. The result shows that the dirt holding capacity of the experimental filter is 5. 01 g, filter resistance and flow injection pollutants is exponential relationship y=2.5233e^0.7566x, filtration ratio remain unchanged basicly with the increase of the pressure drop, the numerical fitting relationship between filtering ratio and solid diameter is β=0.0229x^3.8838, if the solid diameter is greater than the maximum pore diameter, filtering ratio is infinity, filtering ratio of nominal filtration precision 5 μm is 11. 87, its filtering efficiency is 91. 58% , but actual nominal filtration precision 8. 04 μm.
