Great warships

Chapter 244 Investing in the Diesel Engine Factory in the Old District
"President Qin, what does the son of Shishio Hikoda have to do with Karl from MAN?" The matter has been finalized, Shishio Hikota racked his brains, thinking about how to complete the technical transformation of the factory under the premise of 500 million, Lin Bin secretly curiously Ask Qin Tao.

"His son, who studied in Germany, went to MAN Company during his internship, and became a teacher and student with Karl." Qin Tao said: "It is definitely a shame for the son of a machine-making fairy to go to ask others to be his teacher! "

No wonder that Shishio Hikoda agreed so readily. On the one hand, his own side took out the hole cards. Anyway, it's just the money, let's figure it out!If it doesn't work, he will be replaced. On the other hand, it is also because Qin Tao has grasped Yan Tian Shishixiong's weakness and directly hit the vital point.

500 million US dollars is an acceptable price for their Bincheng Diesel Engine Factory. To spend this money on upgrades, just grit your teeth. At this time, Lin Bin is very much looking forward to the prospect of their factory after the upgrade.

"Mr. Qin, thank you for your help." Lin Bin looked at Qin Tao and said seriously: "After the research of our factory committee, we decided to hire you as our factory's honorary consultant. I hope you can accept it."

Honorary Advisor?

Qin Tao looked at Lin Bin curiously, what do you guys want to do?

"Please don't get me wrong, we won't add any burden to you, you don't have to stay here all year round, as long as you come to Bincheng occasionally, you can come and visit us." Lin Bin told Qin Tao: "We know, The salary of the honorary consultant is not enough for you to grit your teeth. This is just a little bit of our intention. I heard that you have been looking for a suitable diesel engine factory. Our factory is willing to cooperate with Mingzhou Shipbuilding Industry Group. "

Qin Tao smiled helplessly: "You guys want to provide support for our factory. We will cooperate if we have the opportunity in the future. This title of consultant..."

"President Qin, please accept it."

"Okay." Qin Tao agreed.In this way, Qin Tao finally stepped into the circle of marine diesel engines. After entering the circle, it will be easier to find a chance to get a certain diesel engine factory under his command.

"It's just that your factory produces low-speed diesel engines, which can't be used on warships. You can try them on freighters in the future. If customers decide to accept our domestic main engines, we will help sell them." Qin Tao promised.

Marine diesel engines can be divided into two-stroke and four-stroke according to the working principle, and can be divided into low, medium and high according to the speed of rotation.

Low-speed diesel engines can rotate more than 100 or even dozens of revolutions per minute. There are also slightly higher four-stroke models that can rotate to three or four hundred revolutions.

Because the speed is very low, there is no need for a reduction gear, and the propeller can be directly driven without a reducer, and some can even be reversed, even the reverse gear is not needed, and because the speed is slow, its life is very long. Tall, just like a turtle.

Moreover, although it is called a diesel engine, it can not only burn light diesel, but some can even burn heavy oil, which is quite economical, and thus has become the first choice for many international ocean-going freighters.

However, there are also disadvantages. This kind of diesel engine is very bulky and has a high volume-to-power ratio. Therefore, it is not suitable for places where every inch of land is expensive, such as warships.

The brand-new frigate planned by Qin Tao uses four 16PA6V diesel engines from the factory in the old area. This is a medium-speed diesel engine.This kind of medium-speed diesel engine has a speed of more than 1000 to more than [-] revolutions per minute.

As for the missile boats that have been mass-produced now, they use MTU's high-speed diesel engines, which are small in size and powerful in power, and can run at more than 2000 revolutions per minute. (This is the case with diesel engines. If you want to step on it at [-] rpm like a gasoline engine, it is impossible. There are also high-speed diesel engines that can speed up to [-] to [-] rpm, which is already very good. The classification of this speed is also roughly It's not that the hero of East China is unprofessional, but there are different opinions.)
Although Mingzhou Shipyard also has large ocean-going cargo ships, they all use imported main engines without exception. On the one hand, it is the customer's request, and on the other hand, domestic diesel engines are not enough.

But after the technical transformation of Bincheng Diesel Engine Factory, their production capacity can be rapidly increased, not only for Bincheng Shipyard, but also for other shipyards. Therefore, Lin Bin hired Qin Tao as a technical consultant, I also want to shine.

However, domestic diesel engines must always be developed, domestic products must be self-reliant, and freighters produced in the future must slowly be equipped with a domestic heart.

At this time, Lin Bin was very happy to hear Qin Tao say this.

"Thank you, Mr. Qin! Without you, the technical transformation of our factory would not be able to go on." Lin Bin was very emotional: "Complete our transformation with the minimum cost, seek truth from facts, and go our own way. This is our responsibility. The most correct choice!"

"Look at these years, our country has introduced so many production lines for color TVs, motorcycles, refrigerators, washing machines, and even automobiles. With the money from the state and the money borrowed from banks, the factories rush to compete with each other. It depends on who imported the production line better. However, after the introduction, a considerable number of production lines cannot operate, cannot produce, cannot create value, this is simply..."

"Waste." Qin Tao gave an accurate word.

"That's right, it's a waste!" Lin Bin sighed with emotion.

After the opening of the country, many advanced technologies were introduced from the West, some of which began to blossom and bear fruit in China, and some were left aside and left unused.

In terms of the automobile industry, the imported Santana is a successful example. FAW spent huge sums of money to import an engine production line from abroad, but ended up throwing it away.

In terms of aero engines, the Spey engine imported from China was such a key project at that time, but what about now?
A lot of things imported at a high price have been wasted. They Bincheng Diesel Engine Factory must not follow such an old path. They must follow a path that suits them!Also have to set an example for other factories.

Moreover, as the country gradually moves closer to a market economy, there will be fewer and fewer projects that rely entirely on state investment and introduction, and most of them need to be carried out independently by enterprises.

"Boss Qin, I heard that the Navy has begun to discuss the proposal of a frigate with a displacement of [-] tons. It is your suggestion." Lin Bin suddenly changed the subject.

This project cannot be hidden. When Wu Shengli began to argue with the Navy, the news spread.

Everyone is shocked.

After all, the most advanced 053H2 frigate currently under construction in China has a displacement of only about [-] tons. Now, it is actually a [-]-ton frigate?

The destroyer under construction is only more than 4000 tons!
Over the years, everyone has been very clear in their hearts that if they take big steps, it is easy to get caught.This step is really not small.

"That's right, we plan to build a new generation of frigates for the navy, with an expanded displacement to install our most advanced domestically-made vertical air defense missile system."

If it wasn't for Qin Tao's involvement, now Hongqi 7 can only be used instead of Hongqi 61 and installed on the frigate to form a 053H3 frigate. As a result, Qin Tao has taken a big step forward.

"I don't know anything else, but you plan to combine two diesel engines, and there are many technical risks in it. Those who oppose you are all considering it from this perspective." Lin Bin said.

Qin Tao helped them a lot, and of course they had to provide Qin Tao with some information.

Wu Shengli didn't tell Qin Tao about these things. On the one hand, it was still early and the horoscope hadn't been written yet. On the other hand, it might be that Wu Shengli wanted to keep silent for the sake of fairness.

However, this technical problem has long been considered by Mingzhou's technicians.

"Then let's use the facts and tell them to shut up." Qin Tao said.

"Mr. Qin, you can always create miracles. Since you have prepared in advance, I won't say more." Lin Bin said: "I used to be classmates with the director of the diesel engine factory in the old district, and he is also very friendly." I look forward to your visit and investigation to their diesel engine factory, and discuss countermeasures together.”

The diesel engine factory in the old district is still waiting!After all, according to the plan proposed by Qin Tao, a warship needs to use four diesel engines, and doubling the number means that the orders in their factory will double. Of course, they are full of expectations.Moreover, the previous frigates used 18E390A diesel engines, which were not produced by their factory. Now they choose their diesel engines, which means big business.

However, if two diesel engines are used to drive one propeller, the problem of paralleling vehicles is really in front of us.

"I won't go to the diesel engine factory in the old district. You and their factory manager are classmates, so please send him a message and ask him to send us the relevant data of the diesel engine so that we can solve the problem of merging cars."

"Okay, this is no problem. I will contact you immediately."

When Lin Bin called the Diesel Engine Factory in the old district, Wu Shengli was investigating here.

"Leader Wu, our factory was founded in 1955. It is one of the 156 key projects during the First Five-Year Plan period. It is also one of the 665 key enterprises in our domestic machinery industry." Wang Tianmin, the factory director, introduced to Wu Shengli with excitement. He wrote: "At present, our factory is already a professional manufacturer of medium and high-speed high-power diesel engines for domestic ships and a complete set of diesel generator sets."

There are many marine diesel engine factories in China, each with its own characteristics. For example, Bincheng manufactures low-speed diesel engines, while theirs manufactures medium- and high-speed diesel engines.

Although it is called the factory in the old area, in fact, they are not in the provincial capital, but in Xingping City, which is [-] kilometers away from the provincial capital.

Wu Shengli is very enthusiastic about the project proposed by Qin Tao. This is definitely not because Qin Tao is his son-in-law, but because Qin Tao proposed a low-cost advanced frigate project for the navy, which is of great significance to the navy.

After it was brought up at the Navy's meeting, relevant technicians began to question the problem of paralleling diesel engines. Therefore, Wu Shengli took a moment to come here to seek a solution.

"Since 78, we have introduced the PA6 series diesel engines from the French Thermal Engine Association. Now we can produce related products, ranging from six cylinders to sixteen cylinders. However, we have no relevant information on this STC technology, and , We can’t solve the problem of paralleling diesel engines.”

Wu Shengli nodded: "I have already heard from the technicians in the capital that if you want to drive two diesel engines of the same power in parallel to drive a propeller, it will be very difficult from a technical point of view."

"Yes, there is no such precedent in the world." Wang Tianmin said: "So, although we are very confident in our diesel engines, we are still cautious in this regard. Perhaps, Mr. Qin He is very capable and has a way to solve related problems."

The expression on Wu Shengli's face was serious: "Yes, there is no precedent in the world. However, in terms of our current strength, when the gas turbine cannot break through for the time being, the combination of diesel engines is our most suitable solution."

If there are advanced gas turbines in the country, how can it be so troublesome to use them!Even if it is a bit more expensive, it is enough to directly use a gas turbine, and even some countries use all-combustion power.

Our own side is still far behind. Even if it is made domestically, the fuel consumption is high and the lifespan is low, so it cannot be used on ships at all.

"Director Wang, Bincheng Diesel Engine Factory is calling." At this moment, a secretary whispered in Wang Tianmin's ear.

So, Wang Tianmin picked up the phone, pressed a button, turned the phone around, and then heard the voice inside.

"Mr. Qin has inspected here and helped me a lot. He said that there is already a plan for combining cars, and you need to provide relevant information on diesel engines."

"There is already a plan for merging cars?" Wang Tianmin was extremely surprised.

Putting down the phone, he was very excited. Wu Shengli was there with a smile on his face. Qin Tao never let him down!Since Qin Tao said yes, it must be possible!

"It seems that I have to go to Mingzhou to have a look."

Wu Shengli said it to himself. On the one hand, he was listening to Qin Tao's report to see how the problem of merging vehicles was solved. On the other hand, he was looking at the air defense ship under construction to see how the progress was. .

"I'll go too, and send materials to Mr. Qin and the others!" Wang Tianmin was also very enthusiastic.

For Wang Tianmin, Qin Tao solved the problem of combining cars, which means that their diesel engines can be mass-produced.

This is not an ordinary diesel engine for vehicles. There are tens of thousands of units per month. The monthly output of large marine diesel engines is often in single digits, and some even produce one in a few months. From the establishment of the factory to now, They have only produced about [-] marine diesel engines.If there are a large number of orders, it means that their income can be doubled several times!

So, when Qin Tao came back from Bincheng, coordinated the production of new parts at Huating, and then rushed back to Mingzhou, a large group of people also came from the distant diesel engine factory in the old district.

"Dad, why are you here?" Qin Tao was extremely surprised when he saw Wu Shengli.

"Well, I heard that there is already a plan to combine diesel engines here, so come and have a look." Wu Shengli said.

It is said that?Qin Tao looked at those people wearing the work clothes of the diesel engine factory in the old area, and understood something in his heart: "You happen to be doing research at the factory in the old area?"

"Ah."

"I just came back too, and the specific progress is not very clear, so let's ask our technicians to introduce it." Qin Tao said: "However, these technologies are under development and have not yet applied for patents, so please keep them secret. discipline."

Wu Shengli nodded: "If someone dares to leak the secret, the Navy will investigate to the end."

For diesel engine factories in old areas, no matter which shipyard wins the bid, it will not affect them. There is no need for them to leak their technology. Moreover, Qin Tao wants to use their diesel engines, which is good for them of.

In addition to Wu Shengli's words, anyone who dares to leak the secrets will have the guts of a bear.

"We handed over the important task of research and development of this parallel car to researcher Zhang Chao. He is from Tsinghua University and has strong capabilities."

Wang Tianmin was at the side, only surprised and moved.

Earlier Qin Tao said that he wanted to apply for a patent, so he was shocked. Now, he heard that there are excellent students from Tsinghua University here, and he is even more shocked. This Mingzhou Shipyard is really Crouching Tiger, Hidden Dragon!

In the conference room, Zhang Chao was also very excited. He opened his notebook and typed the design plan on the screen.

Qin Tao just gave a suggestion at the beginning, but now, Zhang Chao has designed the plan according to the specific performance of the diesel engine and his own needs.

Looking at the precise mechanical perspective, Wang Tianmin felt as if Grandma Liu entered the Grand View Garden, everything was fresh.

"Theoretically, this plan is feasible, but you haven't got our technical information yet, how did you start the preliminary design?" After hearing the exquisite design, Wang Tianmin expressed his affirmation and raised doubts.

"We made the design based on the STC diesel engine technical data of the French Association of Thermal Engines. After all, this diesel engine is what we want to match in the end."

Now it's Wang Tianmin's turn to be embarrassed. They haven't made this kind of diesel engine yet!

"That is to say, this technology can realize the parallel operation of diesel engines?" Wu Shengli doesn't understand these specific technologies, but he can ask the people around him. Now it seems that this technical route should be able to go through.

"That's right, it's absolutely possible. Even if a reduction gear is added to the side, this device can also realize parallel work with the gas turbine." Wang Tianmin said.

The design is so ingenious, especially the clutch, which is absolutely innovative, no wonder they want to apply for a patent!

"Then the next step is to make the machine and conduct a [-]-hour test run on land. If the test run is normal, it means that this technology can be used in the drive of frigates. In the future, all our frigates can use this kind of power. System!" Wu Shengli was also very happy, and immediately made a decision.

"Leader Wu, we don't have this kind of STC diesel engine yet." Wang Tianmin reminded in a low voice.

Here is to build a mechanism for paralleling vehicles. They want to build diesel engines. Now they don't have STC technology, so how can they experiment?

"The ships we build for customers have plans to use this kind of power. The diesels imported from France will arrive soon. At that time, we will find a way to dismantle the turbochargers inside and make imitations." Qin Tao said: " At the same time, due to the increase in power, you also need to strengthen the relevant mechanisms of the engine, such as pistons, crankshafts, connecting rods, etc.”

Wang Tianmin frowned.

Qin Tao is right.

Add a turbocharger to the engine, and the performance of the engine will be improved rapidly, but at the same time, this way of squeezing power will also cause some damage to the engine, and the relevant mechanisms need to be strengthened.

It used to be [-] horsepower per cylinder, but now it wants to increase it to nearly [-] horsepower, which requires the strengthening of various related mechanisms!
How to strengthen?

"You can learn from MTU diesel engine technology, and at the same time, introduce some new equipment and improve your production line. For you, this is also an opportunity for leapfrog development." Qin Tao began to make requests: "For example, in terms of casting , The world has begun to use resin sand molding production lines, so that the cast cylinders will be more precise and can withstand stronger impacts. For other parts, you also need to have special machining centers to improve precision."

The low-speed diesel engine relies on its large size and does not require high strength, but this kind of medium-high speed diesel engine is different.Qin Tao asked them to upgrade their products. Only in this way can they meet the needs of [-]-ton frigates.

"Boss Qin, these improvements require a lot of money!" Wang Tianmin looked distressed.

"You can learn from the Bincheng Diesel Engine Factory." Qin Tao said: "The machine-making gods of the island country are doing research there. With only 500 million US dollars, they can complete the upgrade and transformation requirements for their production lines. Maybe you can do the same for less." Spend money and do great things."

"But we don't even have 500 million US dollars." Wang Tianmin was very frustrated: "How can we compare with Bincheng Diesel Engine Factory?"

Bincheng Diesel Engine Factory produces low-speed marine diesel engines. In the current shipping market, 90.00% of cargo ships are equipped with such engines.

And their diesel engine factory in the old area produces medium and high-speed marine diesel engines. Most of these are used for supporting warships. Now the domestic production of warships is small. Although their factory was established during the First Five-Year Plan, But now, that is, living.

Moreover, their factory is still in the inland area, which is incomparable with the coastal area. They can't get 500 million!

People are more mad than people.

"Use the assets of the factory as collateral, borrow money from the bank, and if you don't upgrade and renovate, you will definitely fall behind in the future, and you may be eliminated in the market competition." Qin Tao said.

"Boss Qin, it's very difficult to borrow money. It's still 500 million US dollars, which is foreign exchange." Wang Tianmin said, "We are not as rich as your Mingzhou Shipbuilding Industry Group."

When he said this, Wang Tianmin suddenly remembered something: "President Qin, can you provide us with money?"

Of course I can't, my money didn't come from a strong wind, Qin Tao thought so in his heart, but in order not to hurt the other party's self-esteem, he didn't say it out.

However, what Wang Tianmin said next made Qin Tao happy: "If you are willing, we are willing to sell part of the shares in the factory."

"You mean, we use the method of injecting funds to buy shares in your diesel engine factory in the old district?" Qin Tao did not expect that there would be such a good thing like a pie in the sky.
