摘要
本文通过对铁路车辆空调制冷剂的流体特点进行分析,结合实际工作经验,确定了利用氦气进行空调制冷管路检漏的新方法,并通过换算了泄漏率的标准值,明确了检漏操作的有效方法和实施效果。
Through analyzing the fluid characteristics of railway vehicle air conditioning refrigerant and combining with practical work experience,determine a new refrigerating pipeline's leakage detection method by helium gas.Through converting the standard value of leakage rate,clarify the effective method and implementation effect of leakage detection operation.
