首都机场线风源装置国产化研制

Localization Development of Air Source Device for Capital Airport Express

针对首都机场线用风源装置进行国产化研制,提出合理设计方案,实现了滑片式空压机国产化,解决了原车空压机存在的润滑油乳化和加油口机壳螺纹损坏问题,并优化了车辆对空压机的控制策略,可与原车风源装置在性能指标、气路电气接口保持一致。与原车风源装置进行对比,体现出国产化方案的优势。进行了型式试验、动静态调试、运营考核,验证了国产化风源装置的性能和可靠性。

In view of the localization development of the air source device used in Capital Airport Express,the paper puts forward a reasonable design scheme,which can realize the localization of the sliding-vane air compressor,solve the problems of lubricating oil emulsification and screw thread damage of the oil filler housing existing in the original vehicle air compressor,and optimize the control strategy of the vehicle to the air compressor,which can meet the performance indicators and match the air circuit electrical interface of the original vehicle air source device.Compared with the original one,the advantages are embodied in the localization scheme.Type test,dynamic and static commissioning test and operation assessment are carried out to verify the performance and reliability of domestically produced air source devices.
