用管道输送东西,对城市居民,特别是高层楼房的居民来说并不陌生,日常生活中用的自来水、煤气都是通过较远的水厂煤气厂送来的。没有管道运输,城市居民的生活是不堪设想的。工业生产更离不开管道运输。近年来,苏联科学家还研制成功了真空管道列车。这种管道列车可以输送各种块状和粒状的物料,还可以输送机器零件,垃圾。真空管道列车由集装车数节编组而成。头部和尾部各挂一节气力牵引车,通过牵引车前后两侧管道内所形成的真空条件来推动列车前进。
Pipeline delivery is not new to urban residents, especially those living in high-rise buildings. Tap water and gas are used in daily life from faraway waterworks. Without pipelines, the lives of urban residents are unthinkable. Industrial production can not be separated from the pipeline transportation. In recent years, Soviet scientists have also developed a vacuum pipeline trains. This tube train can transport a variety of block and granular materials, but also can transport machine parts, garbage. Vacuum tube train by the number of trucks assembled. The head and the tail each hang a pneumatic tractor, through the tractor front and rear sides of the pipeline formed by the vacuum conditions to promote the train forward.
