The invention discloses an intelligent re-pressing method for a vacuum pipeline of an ultra-high-speed maglev train. The re-pressing process is divided into two stages, the gas flowing state in the first stage is a supercritical flowing state, the negative increment flow compensation method is mainly adopted in the first stage to reduce impact generated by air inflow, and facilities in the pipeline are prevented from being damaged due to gas impact. The gas flow state in the second stage is a subcritical flow state, and the flow loss caused by the change of the flow state is compensated mainly by adopting an incremental flow compensation method in the second stage, so that the re-pressing working efficiency is improved. Compared with a traditional re-pressing system, the working efficiency can be improved by 22.78%.

    本发明公开了一种超高速磁悬浮列车真空管道智能复压方法。复压过程分为两个阶段,第一阶段的气体流动状态为超临界流动状态,该阶段主要采用负增量流量补偿方法来降低空气流入产生的冲击,避免管道内的设施因气体冲击而造成损坏。第二阶段的气体流动状态为亚临界流动状态,该阶段主要采用增量流量补偿方法来弥补因流动状态变化而导致的流入流量损失,进而提高复压工作效率。与传统复压系统相比,可提高22.78%的工作效率。
