前进型蒸汽机车自从使用以来,配汽系统因故障而造成的机破事故屡有发生。一般情况是,机车在运行过程中排汽音响突变,随即发生配汽失效,机车不能继续给汽运行。停车检查可发现半径杆弯曲,解体检查能见到汽室套和汽室阀有不同程度的损坏。这类事故给安全行车带来直接威胁,已引起有关单位的注意。大同机车工厂、瓦房店机务段等单位对配汽系统故障造成机破事故的原因及其防止办法作了研究分析。本文将对这类事故的原因和防止措施提出一种新的见解。
Forward steam locomotive since the use of the steam distribution system due to failure caused by machine failure occurred frequently. The general situation is that locomotives in the course of running exhaust sound suddenly changed, with the gas failure, the locomotive can not continue to steam run. Parking inspection can be found radius rod bending, disintegration inspection can see the steam chamber sets and steam chamber valve have different degrees of damage. Such accidents pose a direct threat to safe driving and have drawn the attention of relevant units. Datong locomotive factory, Wafangdian locomotive depot and other units of the gas distribution system failure caused by the machine broken accident prevention measures and made a study and analysis. This article will provide a new insight into the causes of and prevention from such accidents.
