关于货物列车制动主管定压统一问题的探讨

Discussion on the Issue of Reunification of Constant Pressure of the Cargo Brake Pipe

文章简要介绍目前我国铁路货物列车制动主管两种规定压力并存的情况,追溯了货物列车出现600kPa列车制动主管定压的根源。论述了将货物列车制动主管定压提高到600kPa引发的诸多问题和安全隐患。指出500kPa列车制动主管压力已经能够满足《技规》有关要求,600kPa制动主管定压在目前货物列车基础制动装置设计不变的情况下难于达到预期效果和作用,也和现阶段制动技术不相适应。从而认为将全铁路货物列车制动主管压力统一到500kPa是比较科学合理的,建议铁道部组织有关专家对其可行性、安全性做出综合评估。

The article briefly describes the coexistence of two provisions of the pressure situation on China railway freight train brake pipe,and traces the source of constant pressure of 600 kPa train brake pipe on freight train, and discusses many problems and security risks caused of the freight train brake pipe pressure to improve to 600 kPa, and pointed out that the 500 kPa train brake pipe pressure has been able to meet the requirements of ＂technical regulation＂, The 600 kPa brake pipe pressure is difficult to achieve the desired effect and role in the same freight trains foundation brake design, and incompatible to the current braking technology. Thus, believe that the whole railway goods train brake pipe pressure unification to 500 kPa is more scientific and reasonable; it is recommended that the Ministry of Railways has organized experts to make a comprehensive assessment of its feasibility, safety
