标准范围
本文件规定:a) 在循环流动条件下,对液压流体动力滤芯进行连续注入污染物的多道过滤性能试验。b) 确定污染物容量、颗粒去除和压差特性的程序。c) 目前适用于平均过滤比大于或等于75(颗粒尺寸)的液压流体动力过滤器元件的试验≤25μm(c),且最终试验系统储层重量水平低于200 mg/L。有必要通过验证确定可用于试验设施的流速范围和较低粒径限制。d) 使用ISO12103-1 A3介质测试灰尘污染物和测试液体进行测试。本文件提供了一种试验程序,该程序可产生可重复的试验数据,用于评估液压流体动力滤芯的过滤性能,而不受静电电荷的影响。本文件适用于三种试验条件:1) ?基准上游重量分析水平为3?mg/L。2) ?基准上游重量分析水平为10?mg/L。3) ?基准上游重量分析水平为15?mg/L。
This document specifies:a) A multi-pass filtration performance test under cyclic flow conditions with continuous contaminant injection for hydraulic fluid power filter elements.b) A procedure for determining the contaminant capacity, particulate removal and differential pressure characteristics.c) A test currently applicable to hydraulic fluid power filter elements that exhibit an average filtration ratio greater than or equal to 75 for particle sizes ≤25 μm(c), and a final test system reservoir gravimetric level of less than 200 mg/L. It is necessary to determine by validation the range of flow rates and the lower particle size limit that can be used in test facilities.d) A test using ISO12103-1 A3 medium test dust contaminant and a test fluid.This document provides a test procedure that yields reproducible test data for appraising the filtration performance of a hydraulic fluid power filter element without influence of electrostatic charge.This document is applicable to three test conditions:1) Base upstream gravimetric level of 3 mg/L.2) Base upstream gravimetric level of 10 mg/L.3) Base upstream gravimetric level of 15 mg/L.
