China has made high-speed rail the number one in the world, and is now vigorously developing higher-speed maglev high-speed rail. Because of the very high cost, many people do not understand why they insist on research and development?
Zanty is a global solenoid supplier. We are very interested in all electromagnetic applications that can improve people's lives. The solenoid valves we produce have made great contributions to life automation, industrial automation and office automation. Now, Let us talk about why our country insists on the development of maglev high-speed rail.
1. Maglev high-speed rail still has an advantage in per capita cost
The per-capita fuel consumption of an airplane is 0.36 tons per 100 kilometers, and the per-capita power consumption of ordinary high-speed rail is 4.5 kWh per 100 kilometers. From a simple comparison of energy consumption per person per 100 kilometers, airplanes are about 3.5 times that of high-speed rail. There is no data on the power consumption of magnetic levitation, but there are rumors on the Internet that maglev expert Chang Wensen said before that the power consumption of medium and low speed maglev trains used for the S1 line is 16% higher than that of ordinary wheel tracks. With technological breakthroughs and advancements, the efficiency and per capita power consumption of maglev trains will continue to decrease. According to the plan of the manufacturer CRRC Sifang, the 600-kilometer high-speed maglev project is currently still in the test phase. The test line will be tested around 2022. The specific time for the engineering prototype to roll off is the second half of 2020. Since the high-speed maglev test vehicle rolled off the assembly line last year, the high-speed maglev train has been included in the layout planning of many provinces and cities, and plans to build a super maglev have been reported in Hubei, Sichuan, Guangdong, and Hainan.
2. Policy support and encouragement
The 'Outline for Building a Transport Powerful Country' issued by the central government last year mentioned that it is necessary to rationally arrange the 600-kilometer-level high-speed magnetic levitation system. The breakthrough of the key technology of magnetic levitation is also one of the national special plans for scientific and technological innovation in the transportation sector during the 13th Five-Year Plan. The Politburo meeting just held also called for active expansion of effective investment and strengthening of investment in traditional infrastructure and new infrastructure.
3. Domestic demand to stimulate the economy
In the first quarter of 2020, GDP fell by 6.8%, and economic development faced unprecedented challenges. Infrastructure has always been a major stimulus to GDP. At present, high-speed rail has been undergoing large-scale construction for more than a decade, and it is almost completed, and it is about to start upgrading.
4. The most important thing is the strategic need
High-speed rail has once become China's external business card, just like 5G corresponds to the upgrade of 4G, whoever masters the technology first can gain the initiative in the future market and earn market profits. At present, 5G has gained advantages in China. Compared with the upgraded magnetic levitation of high-speed rail, it must continue to maintain its advantages.
Zanty has developed and produced solenoids and solenoid valves for 30 years, and has a wealth of research experience in electromagnetic mechanics. At present, we have several large tubular solenoids used in high-speed rail and other rail transit. You can learn more about it.
