摘要
介绍了刷式密封的原理、结构、性能以及应用与发展,对刷式密封进行了模拟航空发动机工作条件的340h耐久试验。试验结果表明:国产和进口刷环的密封泄漏特性基本相同;刷式密封的密封特性明显优于篦齿密封的。
The principle, structure, performance, application and development of brush seal are presented. A durability test is made for 340h under simulated aeroengine operating conditions. Test results have shown that the seal/ leakage performance of bristle packs made in China and imported is basically the same, and that the performance of brush seal is evidently superior to that of labyrinth seal .
