摘要:
对涡轴发动机压气机叶片附着物进行分析,根据附着物特征研究了针对性的清洗介质并进行了实验验证,为压气机性能恢复奠定了基础。采用扫描电子显微镜、热重分析、红外光谱等方法对压气机叶片附着物进行分析,结果表明压气机导流叶片和静子叶片附着物的颗粒状态、元素含量、有机物类型等特征存在明显区别。利用分析得到的附着物特征提出了新型的水基微乳型清洗介质,实验表明新型清洗剂对压气机附着物的清洗效果良好。对清洗剂的金属材料腐蚀性能进行验证,实验表明新型清洗剂具有良好的缓蚀性能。

Abstract:
In the paper, attachments on compressor blades of turboshaft engine are analyzed, and a kind of cleaning medium is developed according to its characteristics. The cleaning medium is verified by experiments. This study lays a foundation for compressor performance recovery. Firstly, attachments on compressor blades are analyzed by means of scanning electron microscopy, energy dispersive spectrometer, thermogravimetric analysis and Fourier transform infrared spectroscopy. The analysis results show that there are obvious differences between attachments on guide blade areas and stator blade areas such as particle morphology, element content and organic types etc. Secondly, a new kind of water-based micro-emulsion cleaning agent is developed for removing the attachments according to their characteristics, and experimental results show that the novel cleaning agent has a good cleaning effect on the compressor attachments. Finally, metal corrosion resistance experiments are verified, and the results show that the novel cleaning agent has a good corrosion inhibition performance.
Key words:    turboshaft engine    compressor blade    attachments    cleaning agent
