SS_(4B)型机车制动机高速电空阀故障分析及对策

Analysis and solution of SS_(4B) braking system high-speeed electric air valve

对SS4B型制动机高速电空阀动作的原理做了相关介绍,对在段运行机车高速电空阀经常出现故障的原因进行了分析,研究表明:杂质对高速阀故障的出现有很大的影响,改善空气管路的质量,减少杂质的出现,能有效地减少高速阀故障的发生。

In this paper, the principle of SS4B braking system high - speed electric air valve action is introduced, analysis was carried out to analysis the reason, running of high - speed locomotive electro - pneumatic valve often appears failure, il was showed that impu- rifles have great influence on high- speed valve failure, improw＇, air quality, reduce the presence of impurities, can effectively reduce the occurrence of high speed valve fault.
