摘要/Abstract

摘要： 以纤维直径为3.42 及平均孔径为23.6 和孔隙率为95.07%的玻璃纤维非织造布作为过滤介质，以颗粒直径为13.076 的A3粉作为杂质颗粒，并且以动力粘度为1.275×10-2 Pa?S的YH-15机油为试验油液，利用D-30多次通过试验台模拟汽车机油滤清器的过滤过程并且测试过滤性能。建立了杂质颗粒拦截模型，根据测试结果计算出过滤材料和纤维的过滤效率以及QF值。实验结果表明，随着时间和杂质质量的增加，玻璃纤维非织造布两侧的压差增加。玻璃纤维非织造布的过滤效率大于玻璃纤维的过滤效率，并且变化趋势相同。利用QF值能够结合压差及过滤效率两个变化参数来表达过滤效果，并且 QF值随着杂质颗粒直径的减小和过滤时间的增加而减小。

Abstract: It is used the fiber diameter of 3.42 and average pore diameter and porosity of 23.6 and 95.07% of glass fiber nonwoven as the filter material, then use the grain diameter of 13.076 A3 powder as impurity particles, and the dynamic viscosity for 1.275×10-2 Pa ? S of YH-15 engine oil as the testing liquid. So the D-30 multiple-experiment equipment was used to simulate the automobile engine oil filtration process and filter performance. According to the test results, firstly establishing impurities particle interception model and calculating the filtration efficiency of nonwoven and fiber and QF. The experimental results indicate that the pressure drop of glass fiber nonwoven increases as the increasing of time and particle mass. Additionally, the filtration efficiency of nonwoven is higher than fiber, and have the same change trend. The QF value can be used to express the filtration effect of glass fiber nonwoven, and the QF decreases as the decreasing of impurity particle diameter and the increasing of filtering time.

Key words: quality factor, filtration material, filtration effect, impurity particle, filtration time
