HX_D3B型机车列车管不跟随均衡风缸减压问题的研究

Study on the train pipe pressure reduction problem for HX_D3B locomotive

HX_D3B型机车在不使用机车自动换端功能转而采用手动换端作业模式下,连挂车辆进行换端操作时出现列车管不跟随均衡风缸减压的现象。通过对该型机车CCBⅡ制动系统部件工作原理的分析,查找原因,并探寻解决方案。

When the HXD3 B locomotive in changing end operation use the manual mode instead of automaticmode,the train pipe pressure does not reduce following that of the equalizing reservoir. Through the analysis of the work principle of the CCB II braking system of the locomotive,we found the causes and put forward the solutions.
