specific Embodiment approach

[0014] The specific implementation of the operation air extraction system in this case is as follows:

[0015] When the car body is running, start the running air extraction system given in this case. Due to the high-speed running of the car body (running direction (5) such as figure 1 As shown in ), the gas in front of the car body is compressed, and the compressed gas enters the air extraction device through the air inlet (1).

[0016] For the gas entering the extraction device, such as figure 2 Shown is a multi-stage compression, radiant cooling approach to achieve the desired final compression ratio.

[0017] After the first stage (1# compressor (15)) adiabatic compression, along with the raising of gas density and the raising of temperature, the pressure of gas is also improved relatively substantially. When the (density) compression ratio is 80, the temperature reaches 1286K, and the air pressure increases nearly 350 times. However, if the air pressure in the vacuum...

Abstract

The invention provides a method and a device for carrying out air extraction on a vacuum pipeline by an air suction device on the front end of a vehicle in the driving process thereof for vacuum pipeline superspeed transit. Namely that an air collection opening is arranged on the most front part of the vehicle, and then a large capacity compressor is arranged, and collected air is stored in a low-pressure air storage tank nearby. A control room is arranged on the front part of a running direction, a high-pressure air storage tank is installed behind the control room and the large capacity compressor, different grades of compressors are arranged, and finally a radiation heat dispersion device is arranged. The system can be used as a device for extracting the air additionally for the vacuumpipeline or for a vacuum tunnel, aiming at maintaining a rated vacuum degree; when the air pressure in the vacuum pipeline is higher than the rated air pressure, the running air extraction system is used for air extraction; and the system can also be used as an air extraction device for reducing the air pressure of the vacuum pipeline from normal pressure. The running air extraction system can beinstalled on a special vehicle body, can also be commonly installed on passenger-carrying vehicle bodies, and simultaneously accomplishes the operations of vacuum-pumping and pressure reduction of thevacuum pipeline.

Description

technical field [0001] The invention relates to a vacuum pipeline ultra-high-speed traffic system in which a vacuum pipeline is sucked by an air suction device at the front end of the vehicle during vehicle running, and belongs to a combination example of the vacuum pipeline transportation technology and the vacuum forming technology. Background technique [0002] Because the vacuum pipeline traffic line only realizes rough vacuum or low vacuum, when the vehicle is running, the residual air will still produce the piston wind effect. The dynamic high pressure generated at the front of the vehicle running in the vacuum pipe constitutes running resistance, which hinders the increase of vehicle speed and increases the power consumption of the vehicle. However, the dynamic high pressure generated at the front of the piston wind can be transformed into a vacuum maintenance for the line. Accordingly, the present invention provides a "run pumping" system. [0003] An efficient way...
