Chapter 241: Locomotive Core
"Two thousand. Romance starter ○" Navali replied.
"Impossible, they don't want so much, if it's a few I still believe, two thousand is impossible," Ling Shizhe denied the figure Navali said, "You have dealt with them, then you must know what their current situation is, this bus is a typical luxury bus, can the people over there afford to sit down?" Also, if you want to buy it there, at most it will be for high-ranking officials to go out for inspections, and a few will be enough, and there will be 2,000 vehicles there. ”
Ling Shizhe wondered if Navali had been deceived, after all, they had no contact with that side for almost 20 years, plus Hong Kong itself was in chaos, and it was normal to encounter scammers, or Navali was lying, what good was this lying to him, the transaction of 2,000 passenger trains was a big list, and every link of the transaction procedure had to be strictly controlled, if it was a lie, it would soon be exposed, and then Navali would not only be covered and fucked, but also face prison.
Navali won't be so stupid, he has a bright future now, there is no need to joke about the rest of his life, but then Navali told him: "No boss, the other party is not a liar, I personally went to the Xinhua News Agency office in Hong Kong to contact him, that person I met when I was young, it was a person over there, I swear by my honor, the other party is not a liar." ”
Seeing him so stubborn, Ling Shizhe didn't know what to say for a while, if it was in the 90s, the mainland wanted to buy 2,000 luxury passenger trains, he wouldn't have any doubts, but now it's only 76 years, and ten years of culture/revolution have already put this disaster-ridden country. It was full of holes, and many people who did not have enough to eat fled south to Hong Kong. are so poor that they jingle and travel by luxury passenger train. Just kidding.
Navali seemed to see Ling Shizhe's thoughts, and explained: "That person's name is Xu Weidong, twenty years ago he was a clerk in charge of errands at Xinhua News Agency, and now he is already the deputy director of the office, and I contacted him more than a month ago. Boss, although Bombardier has not had any business dealings with the mainland since then, we have not completely broken off contact with each other over the years, and they have entrusted us from time to time to help them find some information, until you annexed Bombardier. There was no contact between the two sides. After the company introduced the DBME bus from East Germany, I re-contacted him in order to open up sales. ”
It seems that it shouldn't be a liar, Ling Shizhe breathed a sigh of relief, and then his eyes widened: "They entrusted you to find some information!" What information are you looking for? ”
Navali was startled, looked at the excited Ling Shizhe and was puzzled, reacted instantly, and said: "It's not what you think, Bombardier is a regular enterprise." It's not an espionage agency, and we're not going to get involved in that mess, and they're not going to make excessive demands on us, so we're looking for local monthly magazines and some newspapers. These are public and legal. ”
"Why don't they get it themselves, they have to look for you?" Ling Shizhe still didn't believe it.
"After the Korean War, China has been in a state of blockade by the West. There was no diplomatic relationship, let alone an ambassadorial-level relationship. If China wants to understand the world, it can only do so in this way. Navali smiled bitterly, "Give them regular newspapers and monthly magazines." It's over in '72, you know, President Nixon's visit to China, the ice in Sino-American relations began to break, and from where they didn't need us to send them regular newspapers. ”
"Aren't you afraid that someone will stuff some cheat sheets in it? Once you are caught by customs, you are out of luck. ”
Navali smiled proudly and said: "We are not afraid, because the Canadian government nodded, in fact, a few years after the Korean War, the United States regretted fighting such a war with the Chinese volunteers in North Korea, do you remember the American General Clark who signed the Panmunjom ceasefire agreement?" He said that we fought the wrong war at the wrong time, in the wrong place, and with the wrong opponent.
At the beginning of the war, the White House and the Pentagon meant to drive the other side back north of the 38th parallel, but what no one expected was that General MacArthur actually led his troops across the 38th parallel and almost knocked down the Yalu River. President Truman was very angry with MacArthur's behavior, because it would anger the Soviet Union and trigger World War III, which already had a nuclear bomb.
No one thought that the Soviet Union did not participate in the war, but China did, and this fight was four years, not to mention the loss of troops and generals, and the United States also suffered heavy losses economically. A few years later, the Cold War entered a white heat, and Sino-Soviet relations began to decline, and at that time, President Eisenhower wanted to repair relations with China, but the war in the past few years and the prevalence of McCarthyism made no one dare to raise this issue.
China wanted to understand the world, so it approached us, and of course we had to report such a big matter to the government, and within a few days the government issued a notice -- agreed. The information I got was that the Canadian government got in touch with the United States as soon as possible, and only after getting the nod from the White House did the Canadian government agree. ”
I didn't expect that the War to Resist US Aggression and Aid Korea in history would have such an unknown history. In his previous life, Ling Shizhe watched a famous CCTV military program, which episode happened to be broadcast to analyze the historical causes of the War to Resist US Aggression and Aid Korea, and a well-known domestic military expert said at that time that if the two sides had a transoceanic telephone at that time, as long as the leaders of the two sides passed the words, the war could have been completely avoided.
At that time, Ling Shizhe thought that the military expert was talking nonsense, but now it seems that it is not unreasonable, since the Korean War was fought, the wave of anti-war in the United States has been continuous, and even within the United States, there is constant controversy over this issue.
The United States made several mistakes, the first of which was that none of them expected that MacArthur would lead his troops to rashly cross the 38th parallel without obeying orders, and the battle was very smooth, and there was almost no resistance along the way, which made the US military proud.
Second, it miscalculated the Soviet Union, and even more so China, and misanalyzed geopolitics, and the United States did not understand that the Korean Peninsula was actually a buffer zone between China, the United States, and the Soviet Union, and that maintaining the status quo between the two countries on the Korean Peninsula would be beneficial to everyone, and that once the situation of the division of the North and the South was destroyed, only the three parties would be harmed, and no one would be the winner.
You don't see it. Later, Jin Sun wrote a letter to Lao Mao to reunify the Korean Peninsula again. Hoping to gain China's support will not be categorically rejected. Then Jin Sun went to the Soviet Union. As a result, Brezhnev made the same choice as Lao Mao.
After a short sigh in his heart, Ling Shizhe said to Navali: "Even if what you said is true, I think you should stop, so as not to do useless work." Don't you see, since January this year, there have been major events in Chinese mainland almost every month, and the political situation is turbulent. In such a strange situation, they still have to buy 2,000 luxury passenger trains, don't you think this makes sense? And even if they really need it. But 2,000 luxury passenger trains involve a lot of money, right, they have so much foreign exchange to buy? ”
After speaking, Ling Shizhe patted Navali on the shoulder, and got out of the car and left.
Maybe the mainland really needs some high-end passenger trains, but it will never be DBME, at least not now, 76 is an extremely special year, and the business that Valli wants to do with that side, 99% will be yellow, and they will be busy with their own affairs in the next few years. There was a heart to buy Navali's luxury trains.
After leaving the train, Ling Shizhe looked around the train factory.
On July 17, the 21st Olympic Games will be held in Montreal, and the whole country is going all out to make final preparations for this Olympic Games. In February this year, Canada announced the mascot of this Olympic Games, an adorable beaver amik.
This Olympic Games can be described as costly, using many modern scientific and technological achievements. In the northern part of the city, the Olympic Center was opened, and a large stadium, swimming pool, velodrome, and Olympic Village were newly built. Both the velodrome and the stadium are canopyed. The main venue can accommodate 80,000 spectators. There are two huge scoreboards 20 meters long and 10 meters wide, each containing more than 19,000 light bulbs. From any side of the field, you can clearly see the results displayed on the cards.
In the subway factory, the last two trains of the subway buses customized by the Canadian government for the Olympic Games are about to be delivered, the construction of the car body has been completed, and workers are doing the final pipeline installation and interior decoration.
Different from the casualness of the Americans, the work discipline of Canadians is much better, and they are much more serious and industrious, and dozens of workers are busy in the assembly workshop, doing their own work carefully and meticulously. Seeing Ling Shizhe coming over, he just nodded his head and continued to do the work in his hands.
Then he went to see the locomotive production workshop, because the technology involved in the 240 locomotive is much more complex than the double-decker passenger car, so the first electric locomotive of Ambrera will come out a few months later, because Canada, like the United States, uses the locomotive is the internal combustion engine power system, the electric locomotive is still the first contact, although the subway is also electric-driven, but compared with the real electric locomotive, the former is more like a toy.
The high-voltage rectifier and transformer part alone, the high-voltage pantograph part will be busy enough, and the technical strength of high-power AC and DC motors has not been available to Bombardier, and the previous subway production and operation can not be used at all on the 240 locomotive, and many things have to be re-learned.
For the power transmission of railway locomotives, there are only two options, electric transmission and mechanical transmission, in the fifties and sixties, hydraulic mechanical transmission and electric transmission go hand in hand, especially in some industrial and mining enterprises, because there are certain explosion-proof requirements, it is hydraulic transmission dominates the world.
In the seventies, with the rapid development of computer technology, mechatronics equipment such as electronic commutators went out of the laboratory, and new motors such as brushless DC motors were put into use, which made the cost of high-power DC motors plummet, and electric transmission has developed by leaps and bounds in railway locomotives, while hydraulic transmission is limited by the power limitation of transmission components.
Therefore, in addition to digesting and absorbing the drive motor technology of the former East Germany, Ambrera also had to develop its own high-power drive motor and electric drive system.
The high-power drive motor is the core component of the electric locomotive traction system, and the traction drive system is also known as the "heart of the train" in the industry, and its performance determines the power quality, energy consumption and control characteristics of the train to a certain extent, and also affects the economy, comfort and reliability of the train, which is the key to energy-saving upgrades.
The first generation of the world's rail transit vehicle traction system is the DC motor traction system, and the 240 locomotive uses a DC motor, that is, the high-voltage pantograph draws the alternating current down and converts it into a DC motor to drive the DC motor.
The second generation is the AC asynchronous motor traction system that started in the 70s of the 20th century, and this technology has been applied until the 21st century and is still the mainstream of the world.
The third generation is the permanent magnet traction system with the permanent magnet synchronous motor as the core, Ling Shizhe heard such a sentence in the previous life, that is, the permanent magnet traction system is a revolution, who has the permanent magnet traction system, who has the right to speak on the high-speed rail.
The permanent magnet traction system is composed of two parts: the converter and the motor, of which the converter is equivalent to the heart of the train, the motor is like the muscle of the train, and the motor is mainly responsible for transmitting power, completing the conversion of electrical energy to mechanical energy, and driving the train to run smoothly.
