摘要
液压过滤材料在过滤过程中会出现过滤比严重下降的问题,极大影响了滤材过滤性能的稳定性。首先利用Geodict软件模拟了滤材孔径分布不均匀对过滤性能的影响,结果表明,在平均孔径一定的情况下,滤材的最大孔径越大,滤材过滤性能的稳定性越差;然后采用实验探究了成形网目数对滤材孔径分布以及液体过滤性能的影响,结果表明,当成形网的目数大于等于400目时,不同直径、不同定量的滤材在成形过程中的流失率和孔径分布逐渐趋于稳定,在滤材的物理参数和过滤精度接近时,500目成形网制备的滤材过滤性能的稳定性要高于80目成形网制备的滤材。
The beta ratio of hydraulic filter media decreases significantly in the filtration process,which leads to the shortening of the service life of filter media.Geodict software was used to simulate the effect of uneven pore size distribution on the filtration process.The results showed that under close mean pore size,the larger the maximum pore size of the filter,the worse the filtration stability of the filter.Then experiments were conducted to explore the effect of the mesh number on the pore size distribution of the filter media and their liquid filtration performance.The results showed that when the mesh number was greater than or equal to 400 mesh,the loss rate and pore size distribution of different diameters and different quantities of filter media gradually tend to be stable in the forming process.When the physical parameters and beta ratio of the filter media were close,the stability of filtration performance of the filter media on the 500 mesh forming fabric was higher than that of media prepared on the 80 mesh.
