25T型塞拉门故障分析以及检修工艺的优化
摘 要
客车塞拉门是安装在时速 140 km 以上客车的自动化控制边门，主要装用在25 T型车上。塞拉门是高级别提速客车的重要设备，能较好地保证提速客车的气密性和减小运行风阻的作用，同时具有防
挤压的功能。目前宁局塞拉门主要采用电控气动方式进行控制，现有康尼、法维莱、博得和翼飞4个厂家生产的塞拉门，其中故障率较高的是法维莱塞拉门，而南宁车辆段目前装有法维莱塞拉门的客车共有 36 辆。2011 年全段总共发生塞拉门故障 38 件，其中因塞拉门故障造成客车被中途拦停就发生了4起之多。当塞拉门在运用中发生故障后，将严重地影响客车行车安全，甚至会造成旅客生命财产的巨大损失。因此，必须有效降低和及时处置塞拉门故障，以确保旅客列车的绝对安全。本文针对25T型客车塞拉门系统原理与结构方面的一些特点进行介绍，同时对武广线在运营初期客车塞拉门存在的开关门故障进行了分析，并针对客车塞拉门系统的特点以及运用维修过程中存在的实际问题，大胆地进行实践摸索，将存在的实际问题进行攻关，以解决了检修中的难题。本文介绍了25T型客车塞拉门的机械结构，工作原理及应用，分析了25T型客车运营中塞拉门存在的开关门故障。并针对性的提出了解决方案，为以后25T型客车塞拉门相似故障提供处理经验。

Abstract
The plug door of passenger car is an automatic control side door installed on the passenger car with a speed of more than 140 km / h, which is mainly installed on the 25t type vehicle. The sliding plug door is an important equipment for high-level Speed-up Passenger Cars, which can ensure the air tightness of the speed-up passenger cars and reduce the running wind resistance
The function of extrusion. At present, the sliding plug doors of Nanjing Railway Bureau are mainly controlled by electronic control and pneumatic control. There are sliding plug doors produced by four manufacturers, namely Kangni, favelai, Bode and Yifei. Among them, the favelai sliding plug door has a higher failure rate. At present, there are 36 buses equipped with favelai sliding plug door in Nanning depot. In 2011, a total of 38 plug door failures occurred in the whole section, among which, as many as 4 bus stops were caused by plug door failures. When the sliding plug door breaks down in operation, it will seriously affect the safety of bus operation, and even cause great loss of passengers' life and property. Therefore, it is necessary to effectively reduce and timely handle the sliding plug door failure to ensure the absolute safety of passenger trains. This paper introduces some characteristics of the principle and structure of 25t type passenger car sliding plug door system, and analyzes the door opening and closing failure of the passenger car sliding plug door in the early operation of Wuhan Guangzhou line. According to the characteristics of the passenger car sliding plug door system and the practical problems existing in the process of maintenance, this paper boldly explores the practice, and tackles the existing practical problems to solve the problems The difficult problems in maintenance are solved. This paper introduces the mechanical structure, working principle and application of the sliding plug door of 25t bus, and analyzes the failure of opening and closing the sliding plug door in the operation of 25t bus. And put forward the solution, for the future 25t type plug door similar fault treatment experience.
Key words: 25t bus; sliding plug door system; troubleshooting
