Dongfang is known as the infrastructure madman. All kinds of advanced construction equipment come to the fore, creating a series of impressive infrastructure projects. They open roads in the mountains and build bridges over water. They build bridges hundreds of meters high in the mountains and drill thousands of stones.
Meters of mountain roads, building cross-sea bridges on the sea, and reclamation of land, each project is impressive.
Looking at the West, the layout of the country has remained unchanged for hundreds of years. The city's buildings have not been updated, the railways have not even been electrified, and the power grid has not changed. They still use the ancient method.
In the world of capital, if you don’t have profit, you can’t afford it early. If you have some things, you can just make do with them.
The railways are old and make do, and if there are occasional vehicle collisions, just cancel them. The power grid does not need to be updated, and there is no need for them to update it.
Anyway, Europe is a big place and there is no need for long-distance power transmission, and the power loss is within an acceptable range.
It's different in the east. The electricity produced in the west has to be transported across thousands of kilometers to the east. If there is no suitable transmission mode, the electricity lost in the middle may reach half of the power generated.
above.
As early as 1989, the first high-voltage DC transmission project in the East, that is, the 100kV DC transmission project from the mainland to Zhoushan, was put into operation. The overhead and submarine cable hybrid DC transmission project that transmits power from the mainland to the Zhoushan Island is the first in my country. An industrial pilot project with independent scientific research, design, manufacturing and installation.
You definitely have to do it yourself, because it’s not available abroad.
After the success of this project, Dongfang continued its efforts to build 500 kV, 800 kV, and finally 1,000 kV ultra-high voltage transmission projects.
AC is used for power generation, AC is used for users, and DC is used only for power transmission. This involves the conversion of AC to DC and DC to AC. The medium-voltage DC used on warships has a voltage of only 13,500 volts, which is 13.5 kilovolts.
Such voltage conversion is naturally a piece of cake for Eastern technology, but for Westerners, it is very difficult to achieve.
Now, the French are faced with a huge problem: they have a gas turbine, but they don’t have a suitable generator because it doesn’t match!
How to deal with it?
"Mr. Ntamac, can we ask you to slightly improve the generator? A generator that can match our gas turbine." Duquesne asked cautiously.
"It's impossible, the speeds don't match, we can't do it."
"Can we add a reducer halfway?"
"Then you have to design a reducer specially adapted to the 40-megawatt power. Moreover, we are not responsible for how to match it with other generators after deceleration."
60 Hz alternating current has a cycle every sixty-tenth of a second. The generator must be synchronized with the power grid, which means that the error cannot exceed one-quarter of one-sixtieth of a second. The higher requirement is more than one-tenth of a second.
, Only in this way can we ensure that the wave peaks and the wave troughs meet the wave troughs. If the wave crest meets the wave trough, the whole ship's power grid will be burned down.
It is already difficult for the engine to directly drive the generator to run synchronously. A reducer is added in the middle. The reduction gear has inertia and a gap. The error of this gap is definitely more than one sixtieth of a second.
Therefore, even if it is matched with a reducer, it is not convenient to connect to the grid to generate electricity.
Alternators around the world do not dare to do this, with the exception of hydropower and wind power. These power sources are greatly affected by the outside world. In other thermal power stations, etc., the speed of the unit is strictly limited.
Duquesne frowned: This means they have another expense!
what to do?
You will definitely lose money now!
"The key to solving the problem is Mr. Nicholas. We need to get a breakthrough from him." Lucas said: "I don't believe that there are still old people who live in the mire but are not stained. Every old person is very greedy.
Yes, the key is to see how much you can impress him."
Although the last bribery failed, and Boris heard that he has been sentenced to decades, but they are just unlucky people. What old man is not greedy? It's just greed for more and less.
Duquesne nodded: "It seems that we have to pay more. If we spend 10 million US dollars, can we ask him to increase the price by 100 million US dollars?"
"The key is that the money should be given quietly and no one can see it." Lucas said: "How about we ask him to buy a certain stock?"
There are many ways to give gifts. Giving them directly is the simplest and most silly. There are many ways to give gifts quietly.
"Okay." Duquesne said, "I'll try it."
Duquesne returned to the banquet hall with a sad face. The banquet here was still going on. He forced out a smile again, picked up the wine glass, and walked towards Nicholas.
"Your Excellency Nicholas, I'm very sorry. I just went out for a while. Come, let me toast you and apologize."
Nicholas smiled, raised his glass, raised his neck, and drank it all in one gulp.
Duquesne could only drink the wine in his stomach. This was the 1982 Lafite and it needed to be tasted. This Nicola drank it all in one gulp. What a waste. He couldn't say anything, he could only drink it.
You can drink along, otherwise you may be considered dishonest.
After finishing the drink, Duquesne dismissed the others with his eyes, and then whispered to Nicholas: "Your Excellency Nicholas, I just heard some good news, do you want to know?"
"explain."
"Your Excellency Nikolai, Volkswagen and Dongfang's Golden Sun Automobile Company have reached an agreement. Volkswagen will provide capital, Dongfang will provide technology, and each will hold half of the shares to open a brand new electric car factory in Germany. A few days later,
This project will be officially announced to the public, and by that time, Volkswagen's stock will definitely rise significantly. If you buy Volkswagen's stock now, you will be able to make a lot of money by then."
Nicholas shook his head: "I have no money."
This chapter is not over yet, please click on the next page to continue reading the exciting content! "You only need to come up with a small part of the money, and the rest can be financed through institutions, with up to ten times the leverage. For example, if you come up with 100,000
With US dollars, you can leverage one million US dollars of capital to invest in the stock market. When the stock price rises sharply, you can earn several million US dollars from it. If you use one million US dollars, you can earn several million US dollars.
Ten million."
This is the scariest thing about stock trading. If you only rely on your own funds to trade stocks, the most extreme situation is to lose all your principal. However, the essence of stock trading and gamblers are the same. After making a small profit, you will no longer
To satisfy my principal, I invested 100,000 and only earned 200,000. If I had invested 1 million, wouldn’t I have earned 20 million?
Under this kind of thinking, people who speculate in stocks will borrow money, increase leverage, and even use usury. In the end, their dreams of getting rich are shattered and they are still in debt.
"I don't have money, and I don't do these things." Nicholas said: "I am a duty-bound person. I just need to do my job well."
Nikolai didn’t take the bait?
Duquesne was unwilling to give in: "If you don't have the principal, we can lend you the principal. After you make money, you only need to repay our principal."
Nicholas continued to shake his head: "No, I'm here for the navy's amphibious assault ship. I can't have any financial dealings with you. Otherwise, when I go back, I will end up like Boris."
Duquesne suddenly reacted: No bribery method can impress His Excellency Nicholas. This is not a question of the amount of money, but a question of position.
When the tender was first invited, Boris was beaten because he accepted a bribe. Similarly, there will be many eyes watching. If Nikolay accepts a bribe from the French, he will also be found out, and Nikolai will be with him.
A fate for Boris.
Therefore, this business will be a normal business and there will be no evil ways involved.
what to do?
If you act in full compliance with the contract, wouldn’t you be at a loss?
Duquesne's face looked a little ugly.
After the meeting ended, Nicholas walked out of the banquet hall with brisk steps and went straight to the airport. He was not even willing to stay in France for a while. After returning to Moscow, he picked up the phone and dialed the familiar number.
.
"Qin, this is Nikola." Nikola said with a smile on his face: "I heard that your Golden Sun Motors and Volkswagen have reached a cooperation agreement?"
"Really? I'm not sure either. I'll ask you and call you back later."
Nicholas had a sneer on his face.
A few minutes later, the call came back.
"Qin, how is the situation? What, is this true? Will Volkswagen's stock price rise?"
"Will your Golden Sun Auto's stock rise? Okay, then I'll buy some Golden Sun Auto's stock. Is the price high? Don't be afraid of the high price. Buy a few million shares first!"
A gentleman loves money and gets it wisely. Nikola will not ask for French money. It is too dangerous. However, of course, Qin Tao's automobile company's stocks must be bought to support it.
Putting down the phone, he looked at Zaitsev who was driving: "After we go back, set up an investment company in the name of your brother, and then buy some shares of Golden Sun Auto from the East. It will be completed within three days and sold out in a month.
.”
"Yes." Zaitsev nodded.
France.
After sending Nicholas away, Duquesne told Lucas about the matter. Lucas' face was also extremely ugly: "It seems that I can only ask the Easterners."
He didn't hold out any hope. After all, the price charged by the Orientals would definitely be high.
"Secretary Xu, it's nice to meet you." Duquesne turned on the computer and logged on to ICQ. He saw a familiar person's profile lighted up. He quickly started the video chat and showed a flattering smile.
Mr. Qin cannot be seen every time. It is already very difficult to have a video chat with Secretary Xu.
"Well, what's the matter?"
"Do you have AC and DC transformer equipment?"
"Yes."
"Is it possible to switch any frequency? For example, change more than 100 Hz into 60 Hz."
If the generator remains unchanged, then driven by the UGT40000 gas turbine, the speed will increase, and the frequency will also increase, and it will become more than 100 Hz. Now, what they have to solve is the last step: turning more than 100 Hz into
More than sixty Hertz.
"This requires first converting alternating current of more than 100 hertz into direct current, and then converting it into alternating current at 60 hertz through our equipment."
The frequency can be changed no matter how high it is. As long as it is converted into DC first, there will be no word for frequency.
"How much does such a set of equipment cost? Forty megawatts."
"About thirty million dollars."
Another 30 million, two sets of 60 million!
If you buy a generator from Dongfang, the price is the same, and if you buy an inverter from Dongfang, the price is also the same!
etc!
Although Ducaina knew that he had fallen into a trap, he still held on to some illusions. He thought of something and quickly said: "If I purchase a generator from you, can I get this kind of inverter as a gift?"
"Of course not. A generator is a generator and an inverter is an inverter. However, if you purchase them in a package, I can give you a preferential price."
"How much?"
"The combination of generator and inverter is priced at US$40 million, starting from two sets."
Lucas frowned on the side. This was obviously a trap for the Easterners, but it was a pity that he stepped in!
They planned to purchase a generator from Alstom, which costs about RMB 10 million per unit, but since it didn't work, they had to purchase this kind of power-swapping equipment. The Oriental offered a price of RMB 30 million. The total price was RMB 40 million.
If you purchase a combination of generator and inverter from an Oriental, it costs RMB 40 million. In this case, how should you choose?
It must be from the East. What if Alstom’s generator doesn’t match it? It will cost more then, so it’s better to purchase the complete set from the East.
The price is definitely overpriced and the construction will be a loss. What should we do next?
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "We need to find Brod." Duquesne said: "They asked us to take on this contract at a very low profit. Now
We are about to lose money and lose a lot of money, so we must ask them to fill this hole for us!"
At first, considering that the profit was too low and the risk was too high, they originally did not plan to take on this business, but Brode kept insisting, so they could only bite the bullet and accept it. Now that it has reached this point, they must find DCNS.
Got it!
It was already ten o'clock in the evening. When the two knocked on the door of Brod's house, Brod was wearing pajamas and looked impatient.
"Hey, Duquesne, Lucas, what do you want to do? Is there anything we can't talk about until we get to work tomorrow?"
"We can't wait any longer."
"Why?"
Of course it's because we can't sleep, we can't sleep, and we can't let you sleep!
Duquesne said: "Let us go in, we have important things."
"You can't go in!" Brod wanted to stop him, but he didn't. Duquesne had already walked in.
The sofa was messy, and a blonde girl was lying there, lazily. When she saw a few people coming in, she wrapped herself in a blanket: "I'm going to the bedroom first."
The blanket covered the front, but not the back, leaving an unobstructed view.
"Is she reliable?" Duquesne asked.
"The people in our bureau are very reliable, just tell me."
"Okay." Duquesne said the matter again.
"In other words, you didn't think well at the time and missed the generator?"
"No, this has nothing to do with us. It's all because you pushed too hard." Duquesne's expression changed. This guy actually wanted to pass the blame? He must not be allowed to pass the blame.
"Then what are you going to do?"
"We need the government to provide us with this money. After all, it was originally meant to provide jobs for a large number of boat workers."
"That's impossible. The government's funds are also very tight. It can't even raise funds for a second aircraft carrier. How can it fill this hole for you? You have to find a way on your own."
"If we had a way, we wouldn't come to you. Also, don't expect Da Mao to increase the budget, that's impossible."
"If they don't increase their budget, they won't be able to get our ships. This is a necessary price increase."
"Then our credibility will be completely lost." Duquesne said: "Are you sure you want to do this?"
"It's a pity that we have already imported two gas turbines. Otherwise, we can withdraw from this business." Lucas sighed, and then thought of something: "If our aircraft carrier No. 2 is to start construction, this
The two gas turbines can also be reserved for the aircraft carrier, but we will not do this business!"
"The commencement of aircraft carrier construction is far away, so there's no need to wait," Brod said.
In fact, if they stop now, that would be the most suitable choice. However, the two gas turbines purchased for US$100 million must have a purpose, and Mingzhou Group will never accept returns.
"Moreover, even if our aircraft carrier starts construction, if we want to purchase gas turbines, we can buy them from the UK. Our navy will never use Eastern products."
The British will not allow their gas turbines to be used on Da Mao's warships, but there is no problem if they are used on France's own aircraft carriers. Although British gas turbines are somewhat difficult to produce, in terms of technical indicators, British gas turbines are still very high.
For example, the fuel consumption rate of British gas turbines is very low, which is already comparable to that of diesel engines. Their lifespan is also very long, and the body is even more compact. The East only solves the problem of availability, while the British have to solve the problem of performance. They are definitely the ones with poor performance.
Won't use it.
In this way, the ball kicks around and comes back.
They have no other choice!
"Didn't Da Mao repeatedly increase funding when it renovated the aircraft carrier Asan? We were forced to increase funding for Da Mao, and they would accept it." Broder continued: "By then, they have invested a large amount of money and will not increase the budget.
, we will not deliver the ship to them. The warship is in our hands, so what should we be afraid of? You go and build it first."
"Then we don't have the budget to purchase additional generators and frequency converters." Ducaina said: "You have to find a way to advance this money to us, and we will pay you back after Da Mao increases the budget."
"Okay, let's coordinate with the bank and give you a loan, interest-free." Brod said.
Qin Tao, who is far away in the east, of course does not know the French's choice, but he knows that the French have no choice at all. As for wanting to default on the bill and use warships to blackmail Lao Maozi to increase the price? What a joke! Lao Maozi and Asan are the same.
Is it on the order of magnitude? This is simply seeking skin from a tiger, and I will teach them a lesson.
Moreover, it is best for the Mingzhou Group that the French demand a price increase and threaten with warships, so that Lao Maozi can know who is the most reliable.
Qin Tao has no plans to go out recently. The 003 nuclear-powered aircraft carrier is also a brand new project for Qin Tao. He has never built one in his previous life. Therefore, he has to concentrate on the construction of this aircraft carrier and wear safety helmets every day.
Hat, I went to the dock with Makarov to inspect, feeling full of accomplishment.
The welding arm of the automatic welding machine was moving slowly, and sparks from the arc were flying. Makarov said with emotion: "Mr. Qin, we only thought that as we continue to spread the pie, there will be less and less workers, and the technical school will not be able to train enough."
We had enough talents, but I didn’t expect that the automated equipment would greatly save workers’ labor and improve efficiency.”
"Of course. Our shipbuilding industry was originally a labor-intensive industry, but now it has to become a technology-based enterprise. Even in the future, it will be fully automated. The design office will send the drawings and it will be automated like a production assembly line."
This is really not a joke. The robotic arm automatically cuts the steel plate, sends it to the bending machine, and then automatically transports it to the slipway. The robotic arm places the steel plate in the right position and automatically welds it. It can really achieve full automation.
"Transportation is a big problem." Makarov said: "There is a long distance between each work station, and we still have to rely on people to transport it."
"This is not necessarily the case. We have electric trucks that can walk on their own in the shipyard in the future." Qin Tao said, "It doesn't necessarily have to rely on people."
"Can the truck still walk on its own?"
"Of course, it will definitely come true in the future. By then, trucks won't even need a cab."
Self-driving technology requires very high requirements. At the beginning, it will definitely not be driven on the road outside. After all, the road conditions are too complicated, including pedestrians who run red lights, speeding vehicles, and people who treat the road as their own parking lot...
Autonomous driving cannot adapt to so many situations, but within the factory area, it is already possible to take fixed routes. Even the vehicles that dump containers in some terminals have removed their cabs and are completely dispatched by the control center.
Of course, our own factory can be built in this way, and it should appear within ten years.
"The bulbous bow of our warship has been finished." Nicholas and Qin Tao came to the dock while talking. They could see that the lower part of the first segment of the ship's bow had been finished.
There is a big nose at the beginning.
The existence of the bulbous bow is mainly to reduce the resistance of traveling waves, increase the speed of the ship, and reduce fuel consumption. Such a big nose can reduce fuel consumption by at least 5%. At the same time, for warships, it can also fit inside
Install bow sonar.
"Our previous aircraft carrier bulbous bows used a spherical structure, but the drag reduction effect was not good. Now, our bulbous bows use a spindle-shaped bulbous bow, which is completely designed for drag reduction and has better high-speed performance.
.”
In appearance, it looks like a big nose that has been flattened.
"However, the processing of this shape is more difficult. We have a three-dimensional CNC bending machine that can bend it into the corresponding shape, but if not, it would be too difficult. Asan's aircraft carrier does not have this technology.
Just don’t install a bulbous bow.”
Hearing Makarov's words, Qin Tao smiled: "Really? However, there is nothing that Asan can't do."
