摘要:
［目的］地铁列车空压机出口压力空气干燥度是一个非常重要的指标。如果压力空气中含水量高，就会影响各用风设备的性能，进而影响行车安全。上海轨道交通运维人员在汛期对某些线路列车进行检修时发现，列车供风管路中存在液态水，这是因压力空气中含水量过高而造成的。需要在现有条件下，研究如何调整维修策略，进而改善空压机在汛期的干燥能力。［方法］通过正交试验设计方法，设计了用于分析空压机出口压力空气含水量影响因素的试验方案，给出了使用田口方法分析数据进而确定主要影响因素的方法。［结果及结论］运用该试验方案进行试验，能够分析出影响列车空压机出口压力空气含水量的主要因素，运维人员可据此结论制定适用于汛期的列车空压机维修策略。该正交试验设计方法也可以推广应用至城市轨道交通其他设备运维策略的完善与优化工作之中。
Abstracts:
［Objective］ The pressure air dryness at the metro vehicle air compressor outlet is a very important indicator. If the water content in the pressure air is high, it will affect the performance of various air-using equipment, and thus affect driving safety. When the Shanghai Rail Transit Operation and Maintenance personnel inspected some vehicles on the flood season, they find that there is liquid water in the vehicle air supply pipeline, which is caused by the excessively high water content in the pressure air. Under the existing conditions, it is necessary to study how to adjust the maintenance strategy and thus improve the drying capacity of the air compressor during the flood season. ［Method］ Through orthogonal experimental design methods, an experimental scheme is designed to analyze the influencing factors of air moisture content at the outlet pressure of the air compressor, and a method of using the Taguchi method to analyze the data and determine the main influencing factors was given. ［Result & Conclusion］ By using this test plan to conduct experiments, we can analyze the main factors that affect the moisture content of the air at the outlet pressure of the train air compressor. Based on this conclusion, the operation and maintenance personnel can formulate a maintenance strategy for the train air compressor suitable for the flood season. This orthogonal test design method can also be extended to the improvement and optimization of the operation and maintenance strategies of other equipment in urban rail transit.
