两种典型过滤介质的过滤性能试验研究
Experimental Study on Filtration Performance of Two Typical Filter Media

空气滤清器是保护发动机正常运行的关键部件，过滤介质则是空气滤清器的核心功能材料，为了材料性能的优选迭代，特选择某新型过滤介质与某传统的纤维素纸质过滤材料作为样本，分别进行了特性分析、试验室对比研究和野外测试。研究与测试结果表明该新型过滤介质过滤效率最高可以提高0.4%，容尘能力提高50%以上，新型过滤介质构建空气滤清器需要的二级滤清器壳体空间更小，新材料的热稳定性和环境友好性更好，材料的试验室性能测试和野外测试结论证明了研究结论的准确性。
The air filter is the key component to protect the normal operation of the engine, and the filter me-dium is the core functional material of the air filter. In order to optimize the material performance, two new filter media and a traditional cellulose paper filter material are selected as samples for characteristic analysis, laboratory comparative study and field test. The research and test results show that the filtration efficiency of the new filter medium is increased by 0.4% and the dust hold-ing capacity is increased by more than 50%. The secondary filter shell space required for the new filter medium to build the air filter is smaller, and the thermal stability and environmental friend-liness of the new material are better. The laboratory performance test and field test results of the material prove the accuracy of the research conclusions.
