On January 22nd, China’s high-speed railway welcomed "Allair Warrior". The CR400AF-G new revival of the CR400AF-G, which is independently developed in Qingdao’s Square Share Company, from Beijing to Harbin. As the latest member of the revival number, the CR400AF-G type train group is a "alpine version" of Revival, with a special skill of cold and snow, can run at a speed of 350 kilometers at speed at a low temperature environment of -40 ° C, It is called the world "most antifreeze" high-speed EMU.
"High Cold Edition" Revival is a member of the four-way railway transportation equipment industry in the middle of the middle.
In the four parties in the middle, innovation and progress have been happening: With the continuous improvement of innovative strength, the high-speed EMU will produce the speed of three columns every four days; from here, the urban rail subway train saves more than 100 lines at home and abroad; Product exports to 27 countries and regions in the world, becoming a beautiful "Chinese business card" to overseas.
How is the "high-precision version of the" high-precision version "that can be run at -40 ° C high-speed running through the innovation breakthrough? Jia Xiangjie, director of the Shuangfang Co., Ltd., introduced that the new "Alpine Edition" rejuvenation number from the train used by the train, the electrical components, the steering frame, the steering frame, and the air supply, the air supply is low-temperature design, can Say "cold ability" armed to teeth.
"Joint" is frozen. In low temperature environments, some carbon steel materials in metallic materials may break, so the train is hanging bolt nuts using anti-low temperature chromium molybdenum alloy, stainless steel material, and the train operates under extreme cold weather, bolts, The nut will not break. "Feet" is frozen.
This train group has a wheel non-slip, anti-lock function. When the wheel speed is detected, automatic reduction of braking, traction, and improve friction through the sandstand device, avoiding the snow and snow, while driving the wheel slip.
"Blood vessel" antifreeze.
Train tank, water pipe equipped with "warm baby" – heating plate, electric heating line, box and pipe outside wearing a thick "cotton coat" – cold cotton, cold weather is also available normally. Such innovation has long been integrated into the development of the four parties in the middle bus.
Entering the four-party traffic line of the middle car, a list of the new high-speed EMUs like dragons, ready to go.
The "first" of China’s high-speed rail: China’s first rapid speed is 200-250 kilometers, 300 kilometers per hour, first speed, 380 km high-speed EMU and the first "revival" EMU, is born Here.
The CRH380A drove here, set the first speed of the world’s high-speed rail operation test; "Revival" EMU achieved 350 kilometers of commercial operation speed, making China a country in the world’s high-speed rail commercial operation.
In June 2020, the 600-kilometer speed magnetic floating test sample car was successfully tried by the high-speed magnetic floating research and development of China’s high-speed maglev in China.
Today, from here, there are more than 1,500 standard column high-speed EMUs, which is the largest number of companies in China ‘s online operation.
Accelerate the way to overseas innovation and drive, and help the enterprise "lead" and win the market in international competition. China’s high-speed rail equipment manufacturing enterprise is "China’s manufacturing" representative, and the middle cars are the leader. In recent years, the four parties in the middle cars have gradually enamel the "One Belt" Construction and the high-speed rail "go out" gold opportunity, vigorously promote the international management, actively explore the overseas market, lead the high-end rail traffic equipment to accelerate the "sea". In April 2017, China’s Jakarta to Wanlong Expressway, which was in the construction of Indonesian corporate cooperation, signed in Indonesia Jakarta. The middle car will provide a high-speed EMU for 350 kilometers from the high-speed rail of Jakarta to Bandung.
This has become the first single "walk out" in China’s high-speed rail.
In Singapore, the middle cars were four-party, and 916 subway vehicles were obtained, and the breakthroughs of China’s subway vehicles exported.
In Brazil, September 2017, the four-way cars won 64 urban railway orders, which is the first order of the urban rail vehicles winning in Sao Paulo, Brazil. In Sri Lanka, the four-party in the middle car has accumulated 390 internal combustion engagement orders, accounting for more than 50% of the total number of running vehicles in Sri Lanka, which became the largest railway passenger equipment supplier in Sri Lanka. In Argentina, the TMB has won the total 709 intercity EMU supply contract, which has become the largest intercity motorcycle export order in China.
It is worth mentioning that the 2020 middle cars also overcome the difficulties of new coronal pneumonia, actively promoting the development of overseas markets, successfully signed a number of overseas export orders, "going out" to achieve new breakthroughs.
In June 2020, the four-party motorcycle and the Argentine National Railway Company passed the video mode. The "cloud sign" has the maintenance project cooperation agreement of 709 intercity EMUs in Argentina, and the four-way car will provide the other party to provide maintenance programs, technical services and Maintenance accessories. This is another important result of the enterprise "product + technology + service".
At the same time, China and Laos (Laos) Railway EMU project contract signed that the four parties of the middle car as the leader form a consortium, which will be 160 kilometers to the medium and old railway volume. Subsequently, the Siki Tournament No. 4 (24 vehicles) (24 vehicles) of the National Railway Company "Aramida-Konli" Railway (24)) Internal Combustion – Power Double Power EMUs Order. This is the first dual power rail train project of Chile, and the first dual-active EMU export order for China ‘s rail transportation equipment.
As of the end of 2020, the four-party rail transit of the middle cars has exported to 27 countries and regions around the world, and became a beautiful "Chinese business card" running overseas.
Building a industrial cluster in Qingdao, the truck four-party has driven the rail transportation equipment industry to form an industrial cluster, and aggregate to become a "motor train town" with world influence. The Qingdao Chengyang District, which is located in the middle cars, has gathered in the four-party shares of the middle cars, the four-way manufacturing enterprises of the middle cars and the 3 full-vehicle manufacturing enterprises and Wio, O’., etc., industrial collection level The country’s first place.
In 2020, there is a Qingdao Branch of the Medium Car Research, China Call Technology Park (Qingdao) Co., Ltd., and the Central Current Truck Information Technology Branch established in Qingdao, with the four parties of the middle bus, the leading enterprise traction, Qingdao Rail Transit Industry Cluster Development Output source energy constant kinetic energy.
The continuous increase in scientific research is also helpful for the Qingdao Rail Transportation Equipment Industry.
Here is China’s first national technology innovation center – National High Speed ??Train Technology Innovation Center. At present, the center has formed a high-end thinking, a high-end high-end research institute, including 21 top experts at home and abroad, and 10 well-known high-end scientific research institutions such as SMEs, Beijing Aviation Materials Research Institute, and with German Dresden University. , Germany Tyssenk Furu, many universities, institutions to carry out deep cooperation, gather more than 230 high-end talents. Today, nearly 60% of the EMUs and 25% of the subway vehicles have been taken here, we have built a national new industrialized industrial demonstration base, the national foreign trade transformation and upgrading base, the first batch of strategic emerging industrial clusters in the country, becoming a veritable " High-speed rail heart.
At present, Qingdao is doing a high-end equipment industry chain represented by rail transit. It will create a global influence of advanced manufacturing aggregation land, international high-end emerging rail transit technology strategies, internationally recognized rail transit technical standards leading land, international Leading industry innovation resources intersection. With more innovative talents and projects, Qingdao will release more more powerful new kinens in the rail transportation equipment industry.
