The invention discloses a vacuum pipeline system of a maglev train. The vacuum pipeline system comprises a vacuum pipeline and a vacuum pump set. The vacuum pipeline is a tubular channel which is internally closed and keeps a vacuum environment, and is used for the operation of the maglev train; the more than two groups of vacuum pump sets are arranged along the length direction of the vacuum pipeline at an interval of set length, and the vacuum pump sets are used for vacuumizing the vacuum pipeline, so that the vacuum pipeline obtains the required working vacuum degree and limit vacuum degree; wherein each vacuum pump set is provided with six vacuum pumps, and the six vacuum pumps adopt a variable series-parallel connection large-displacement air exhaust scheme; the vacuumizing efficiency and reliability of the vacuum pipeline can be improved, so that the vacuum degree in the vacuum pipeline reaches the required standard, and meanwhile, the feasibility of the operation environment of the maglev train is improved.

    本发明公开了一种磁悬浮列车真空管线系统,包括:真空管线和真空泵组;所述真空管线为内部封闭并保持真空环境的管状通道,用于磁悬浮列车运行;两组以上真空泵组沿真空管线的长度方向间隔设定长度配置,真空泵组用于对真空管线抽真空,使真空管线获得所需的工作真空度和极限真空度;其中,每组所述真空泵组均配置有6台真空泵,6台真空泵采用可变串并联大排量抽气方案;本发明能够提高真空管线的抽真空的效率和可靠性,使得真空管线内的真空度达到所需标准,同时,提高磁悬浮列车运行环境的可行性。
