摘　　要：针对国内缺少滤芯高压性能测试装置的现状，设计了压缩机干气密封滤芯性能检测装置，利用该装置在实际高压运行工况下对干气密封滤芯性能进行评价，并分析压缩机干气密封系统气源内颗粒物的粒径及浓度情况。结果表明：实验室与现场条件下，相同滤芯的初始压降曲线有较大差别，在现场条件下，滤芯压降曲线呈抛物线形式：测试期间，干气密封系统气源内颗粒物粒径范围为0．3～2．0μm，质量浓度范围为0．01～0．03mg／m^3，气质情况符合干气密封系统进气要求；检测的国产滤芯可在高压工况下正常工作，测试结果可为滤芯设计和国产化工作提供数据支持。At present, devices for testing the high-pressure performance of filter cartridges are absent in China. In this paper, therefore, a device which is used to test the performance of dry-gas-seal filter cartridges in compressors was developed. It was used to evaluate the performance of dry-gas-seal filter cartridges in the real working conditions with high pressure. Finally, the particle matters in the gas source of dry-gas-seal system were analyzed in terms of panicle size and concentration. The test results show that the initial pressure drop curves obtained in the laboratory are obviously different from that in field conditions, even though the same filter cartridges are used. The pressure drop curves obtained in field conditions are in the form of parabola. During the test, the particle sizes of particle matters in the gas source of dry-gas- seal system are in the range of 0.3-2.0 μm, and the concentration ranges from 0.01 mg/m^3 to 0.03 mg/m^3. The gas quality is in accordance with the feed gas requirements of the dry gas seal system. The tested homemade filter cartridges can work properly at high pressure. And the test results can also provide data support for the design and localization of filter cartridges.
