摘　　要：详细介绍了评定核级水过滤器滤芯过滤性能的多次通过法试验台的设计和主要设备、部件、仪表的选择。通过大量的性能验证试验得出:本试验台满足标准滤芯最大水通量4.0 m3/h和最大抗破裂强度0.4 MPa的试验要求;试验系统颗粒分布均匀且稳定,基本满足每一取样间隔内给定尺寸颗粒数的测量值与平均值的偏离≤±15%的标准要求;试验尘注入系统所取各个样品的重量污染度与平均值的偏差基本控制在±5%以内,且平均值与理论值的偏差≤±10%,满足试验平均注入流量与预定注入流量的偏差≤5%的标准要求。The design and the selection of main equipment and instruments of the multi-pass test stand in evaluating filtration performance of a nuclear-grade water filter element were discribed. Some conclusions were obtained through performance tests: the maximum water flux of 4. 0 m3/ h for the standard filter element,and the maximum fracture strength of 0. 4 MPa both meets the test requirements; particle distribution of the test system is uniform and stable,which basically meet the deviation of within ± 15%between the given particle size number of each sampling interval and the average value; for the contamination impouring test,the weight contamination degree of each sample and the average value is controlled within ± 5%,and the deviation between the average value and theoretical value is less than± 10%,and the deviation between the average impouring flow rate and the predetermined impouring flow rate is within ≤5%.
