摘要
为了解决我国西部高原地区电气化铁路开通相关设备配套的需要,进行了DWT-70A型高原铁路电力机车升弓系统用全无油润滑空气压缩机的研制。结合我国西部西藏、青海等省区海拔高度较高的环境工况特点,开展了压缩机热力计算、电机、活塞环、导向环、润滑等相关研究及设计,并进行了振动、冲击、高海拔环境工况模拟考核试验。试验结果表明,该压缩机性能稳定,完全适应高原地区环境工况要求。
In order to address the supporting equipment demands for constructing electrified railroads in the western plateau regions of China,oil-free air compressor for pantograph system of type DWT-70A plateau railway electric locomotives was developed.According to the high altitude working conditions in Tibet,Qinghai and other provinces,research and design were carried out on thermal calculation of compressor,motors,piston rings,guide rings,lubrication,etc.and simulation tests for vibration,shock,high altitude working conditions.The results show that the compressor has stable performances,which fully meets the requirements of working conditions of plateau regions.
