Abstract

The invention discloses a transport system and a producing method of a sub-vacuum duct in a rail transport system. The transport system of the sub-vacuum duct comprises the sub-vacuum duct and a closed train, wherein the sub-vacuum duct comprises a downslope section of inlet normal atmosphere, a closed section of inlet liquid, a sub-vacuum section, a closed section of outlet liquid and an upslopesection of outlet normal atmosphere, the cross section of the duct is in an elliptical shape, silencing materials, force-bearing components, a vent valve, a drain valve, and the like are installed onthe duct, the train is an amphibious train, and the body of the train is made of warer-proof materials. The producing method of the sub-vacuum duct comprises the following steps: A. producing the bodyof the duct; B. installing the vent valve and the drain valve; and C. generating sub-vacuum: producing the duct into a sub-vacuum duct by a method for generating sub-vacuum by pumping liquid. The invention solves the problems of high manufacturing cost of sub-vacuum ducts, inconvenience for passengers to get on and get off the train when the train passes through the sub-vacuum duct and influenceon the vacuum state of the duct. Meanwhile, the invention has the advantages of high efficiency, low energy consumption, simple equipment, and the like.

Description

Technical field: [0001] The invention relates to a railway transportation system and a manufacturing method thereof, in particular to a sub-vacuum pipeline transportation system and a manufacturing method of the sub-vacuum pipeline. Background technique: [0002] At present, high-speed train transportation systems including wheel-rail type and maglev type are all running in an open natural environment. Since the total resistance of the train = rolling mechanical resistance + mechanical loss resistance + air momentum resistance + outflow aerodynamic resistance, in general When the speed of the train is 150-170 kilometers per hour, 75% of the train power is consumed on air resistance, and the faster the train runs, the greater the proportion of air resistance. It can be seen that the power of the train is mainly used to overcome The air resistance of the train running at high speed, but the power needed to overcome the frictional resistance of the train itself is very little, ...
