Chapter 245: Investing in Diesel Engine Factory in Old District
"Mr. Qin, what is the relationship between Hikoda Shizuo's son and Carl from MAN?" The matter has been finalized. Hikoda Shizuo racked his brains, thinking about how to complete the technical transformation of the factory under the premise of five million. Lin Bin curiously asked Ask Qin Tao secretly.
"His son studied in Germany and went to MAN during his internship. As a result, he and Carl became masters and apprentices." Qin Tao said: "It is absolutely a shame for the son of a machine-building **** to become a master of others! "
No wonder Hikoda Jutsuo agreed so readily. On the one hand, he showed his trump card. Anyway, it’s just the money, so let’s figure it out! If it doesn't work, replace him. On the other hand, it's also because Qin Tao caught Hikoda Shizuo's weakness and directly hit the vital point.
Five million US dollars is the price that their Bincheng Diesel Engine Factory can accept. They can spend this money to upgrade and grit their teeth. At this time, Lin Bin is very looking forward to the prospects of their factory after the upgrade.
"Mr. Qin, thank you for your help." Lin Bin looked at Qin Tao and said seriously: "After research by our factory committee, we have decided to hire you as the honorary consultant of our factory. I hope you can accept it."
Honorary Advisor?
Qin Tao glanced at Lin Bin curiously, what do you want to do?
"Please don't get me wrong. We won't put any burden on you. You don't have to stay here all year round. As long as you come to Bincheng occasionally, you can come to visit us." Lin Bin told Qin Tao: "We know. The salary of an honorary consultant is not enough for you. This is just a little bit of our thoughts. I heard that you have been looking for a suitable diesel engine factory. Our factory is willing to join forces with Mingzhou Shipbuilding Industry Group. "
Qin Tao smiled helplessly: "You want to provide supporting equipment for our factory. If there is an opportunity in the future, we will cooperate. What is the title of consultant..."
“Mr. 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 would be easier to find an opportunity to get a certain diesel engine factory under his control.
“It’s just that your factory produces low-speed diesel engines and cannot be used on warships. If you have the opportunity in the future, you can try it on cargo ships. If the customer decides to accept our domestic main engine, we will help promote it.” Qin Tao promised.
Marine diesel engines can be divided into two-stroke and four-stroke according to the working principle. According to the speed of rotation, they can be divided into three types: low, medium and high.
Low-speed diesel engines can turn over a hundred or even dozens of revolutions per minute. There are also slightly higher four-stroke models that can turn to three or four hundred revolutions.
Because the speed is extremely low, there is no need for a reduction gear, and the propeller can be driven directly, eliminating the need for a reducer. Some can even reverse, eliminating the need for reverse gears. And because of the slow speed, its lifespan is very long. Tall, just like a turtle.
Furthermore, 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 has become the first choice for power for many international ocean-going freighters.
However, there are also disadvantages. This kind of diesel engine is very large and has a high ratio of volume to power. Therefore, it is not suitable in places where land is at a premium, such as warships.
The new frigate planned by Qin Tao uses four 16PA6V diesel engines from the old factory. These are medium-speed diesel engines. They must have long service life, high power, and small size. The speed of this medium-speed diesel engine ranges from 600 to more than 1,000 rpm.
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, and can operate at more than 2,000 revolutions per minute. (This is the case with diesel engines. It is impossible to be the same as a gasoline engine and run at 10,000 rpm. There are also high-speed diesel engines that can reach 3,000 or 4,000 rpm, which is already very impressive. The classification of this speed is also roughly It’s not that East China Heroes is unprofessional, it’s because they have different opinions.)
Although Mingzhou Shipyard now also has large ocean-going cargo ships, all of them use imported main engines. This is partly due to customer requirements and partly because domestic diesel engines are not enough.
But after the technical transformation of Bincheng Diesel Engine Plant, 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 take advantage of it.
However, domestic diesel engines must always be developed, domestic products must be self-reliant, and the freighters produced in the future must be slowly 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, I'm afraid our factory's technical transformation would not be able to proceed." Lin Bin sighed with emotion: "Complete our transformation with the minimum cost, seek truth from facts, and follow our own path. This is what we The most correct choice!”
"Look at how many color TVs, motorcycles, refrigerators, washing machines, and even automobile production lines have been introduced in our country over the past few years. Each factory has taken the country's money and borrowed money from banks to compete with each other. It all depends on which imported production line is better. However, after the introduction, quite a number of production lines cannot operate, cannot produce, and 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, China introduced a lot of advanced technologies from the West, some of which began to bear fruit in the country, and some of which were left unused.
In the automotive industry, the imported Santana is a successful example. FAW spent huge sums of money to introduce an engine production line from abroad, but ended up throwing it away.
In terms of aviation engines, the domestically imported Spey engine was such an important project at the time, but what about now?
Many things imported at high prices have been wasted. Their Bincheng Diesel Engine Factory must not follow such an old path. They must follow a path that suits them! We must also set an example for other factories.
Furthermore, as the country gradually moves closer to a market economy, there will be fewer and fewer projects that rely entirely on state power for investment and introduction. Most of them need to be carried out independently by enterprises.
"Mr. Qin, I heard that the Navy has started to discuss the plan of a frigate with a displacement of four thousand tons. It was your suggestion." Lin Bin suddenly changed the subject.
This project cannot be hidden. When Wu Shengli started to demonstrate it with the Navy, the news came out.
Everyone is shocked.
After all, the most advanced 053H2 frigate currently under construction in China has a displacement of only about 2,000 tons. Now, it actually needs to be a 4,000-ton frigate?
The destroyer under construction is only more than 4,000 tons!
Over the years, everyone has been very clear that if we take too big a step, we will easily get hurt. This step is really not a small one.
“Yes, we plan to build a new generation of frigates for the navy with an expanded displacement in order to install our most advanced domestic vertical air defense missile system.”
If it weren’t for Qin Tao’s involvement, now the only option would be to replace the Hongqi 61 with the Hongqi 7 and install it on the frigate to form the 053H3 frigate. As a result, Qin Tao has taken a big step.
“I don’t know anything else, but your plan to combine two diesel engines involves a lot of technical risks. Those who oppose you all think about 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 did not tell Qin Tao about these things. On the one hand, it was still early and the horoscope had not yet been written. On the other hand, Wu Shengli might have kept silent for the sake of fairness.
However, this technical problem has long been taken into consideration by Mingzhou’s technical staff.
“Then let’s use the facts to shut them up,” Qin Tao said.
"Mr. Qin, you can always create miracles. Since you are prepared in advance, I won't say more." Lin Bin said: "The director of the diesel engine factory in the old district and I were classmates before, and he was also very fond of it." I look forward to your visit and investigation at their diesel engine factory and discussing countermeasures together."
The diesel engine factory in the old district is still waiting! After all, the plan proposed by Qin Tao requires four diesel engines for each warship. Doubling the number means that the orders from 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 using their diesel engines means big business is coming.
However, the problem of using two diesel engines to drive one propeller and merging them is really before our eyes.
“I won’t go to the diesel engine factory in the old district. You and their factory director are classmates, so please send him a message and ask him to send us the relevant data of the diesel engine, and we will solve the problem of merging cars.”
“Okay, that’s no problem. I’ll contact you right away.”
When Lin Bin called the diesel engine factory in the old district, Wu Shengli was doing research here.
"Leader Wu, our factory was founded in 1955. It was one of the 156 key projects during the First Five-Year Plan period. It is now one of the 665 key enterprises in the domestic machinery industry." Factory Director Wang Tianmin introduced Wu Shengli with excitement. Said: "At present, our factory is already a professional manufacturer of medium, high-speed and high-power diesel engines for domestic marine use and a complete factory of diesel generator sets."
There are many marine diesel engine factories in the country, each with its own characteristics. For example, the one in Bincheng manufactures low-speed diesel engines, while their side manufactures medium- and high-speed diesel engines.
Although it is called the old district factory, in fact, they are not in the provincial capital, but in Xingping City, fifty 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 and advanced frigate project for the navy, which is of great significance to the navy.
After it was raised at the Navy meeting, relevant technical personnel began to question the issue of diesel engine paralleling. Therefore, Wu Shengli took some time off and came here to seek a solution.
"Since 1978, we have introduced the PA6 series diesel engines from the French Thermal Engine Association, and are now able to produce related products, ranging from six to sixteen cylinders. However, we do not have relevant information on this STC technology, and , we can’t solve the problem of parallel diesel engines.”
Wu Shengli nodded: "I have heard from technicians in the capital that if you want to drive two diesel engines with the same power in parallel to drive a propeller, it will be very difficult from a technical point of view."
The expression on Wu Shengli's face was serious: "Yes, there is no precedent in the world, but with our current strength, when gas turbines cannot break through for the time being, diesel engine paralleling is our most suitable solution."
If there were advanced gas turbines in China, there would be no need for such trouble! Even if it is a little more expensive, just use a gas turbine. Some countries even use full combustion power.
Our own side is still far behind. Even if it is manufactured domestically, its fuel consumption is high and its lifespan is short, so it cannot be used on ships at all.
“Director Wang, Bincheng Diesel Engine Factory called.” 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 visited my place and helped me a lot. He said that the plan for merging vehicles is already available and he needs you to provide relevant information about the diesel engine.”
“Is there a plan for merging cars?” Wang Tianmin was extremely surprised.
He was very excited when he put down the phone. Wu Shengli was there and smiled. Qin Tao had never let him down before! Since Qin Tao said it’s okay, then it must be okay!
“It seems that I have to go to Mingzhou to have a look.”
Wu Shengli said to himself. On the one hand, he was listening to Qin Tao's report to see how the problem of merging vehicles would be solved. On the other hand, he was looking at the air defense ship under construction to see how the progress was. .
“I’m going too, to deliver materials to Mr. Qin and others!” Wang Tianmin was also very enthusiastic.
For Wang Tianmin, Qin Tao solved the problem of paralleling vehicles, which means that their diesel engines can be mass-produced.
This is not an ordinary automotive diesel engine. The monthly demand is tens of thousands. The monthly output of large-scale marine diesel engines is often single digits. Some even produce one in a few months. From the establishment of the factory to the present, They have only produced about 500 marine diesel engines. If there are a large number of orders, it means that their income can be doubled several times!
So, just when Qin Tao came back from Bincheng, coordinated the production of new parts in 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 with vehicles, so I came to take a look.” Wu Shengli said.
It is said that? Qin Tao looked at the people wearing work clothes of the Old District Diesel Engine Factory and understood something in his mind: "You happen to be doing research at the Old District Diesel Engine Factory?"
"Um."
"I have just come back, and the specific progress is not clear. Let's ask our technical staff to introduce it." Qin Tao said, "However, these technologies are under development and have not yet applied for patents, so please keep it confidential. discipline."
Wu Shengli nodded: "If someone dares to leak the secret, the navy will investigate it to the end."
For the diesel engine factory in the old district, no matter which shipyard wins the bid, it will not have an impact on them. They do not need to leak the technology. Moreover, Qin Tao wants to use their diesel engine, which is good for them. of.
Coupled with Wu Shengli's words, anyone who dares to leak the secret will be eating the courage of a bear's heart and a leopard's courage.
“We have given the important research and development responsibility of this parallel vehicle to researcher Zhang Chao, who is from Tsinghua University and is very capable.”
Wang Tianmin was standing aside, only surprised and sighing.
Qin Tao was shocked when he said he wanted to apply for a patent. Now, he heard that there are actually top students from Tsinghua University here, and he was even more shocked. This Mingzhou Shipyard is really a crouching tiger, hidden dragon!
In the conference room, Zhang Chao was also very excited. He opened his laptop and typed the design plan on the screen.
At first, Qin Tao just gave a suggestion, but now, Zhang Chao has designed a plan based on the specific performance of the diesel engine and his own needs.
Looking at the precise mechanical perspective, Wang Tianmin felt like Grandma Liu had entered the Grand View Garden, everything was new.
“Theoretically, this plan is feasible, but you haven’t obtained our technical data yet. How did you start the preliminary design?” After hearing the exquisite design, Wang Tianmin affirmed and also raised questions.
“We designed it based on the STC diesel engine technical information of the French Thermal Engine Association. After all, it is this kind of diesel engine that we will eventually match.”
Now it’s Wang Tianmin’s turn to be embarrassed. They haven’t made this kind of diesel engine yet!
“In other words, this technology can realize the parallel operation of diesel engines?” Wu Shengli didn’t understand these specific technologies, but he could ask the people around him. Now it seems that this technical route should be feasible.
“Yes, it is absolutely possible. Even if a reduction gear is added on the side, this device can also work in parallel with the gas turbine.” Wang Tianmin said.
The design is so clever, especially the clutch, it is absolutely innovative, no wonder they want to apply for a patent!
"The next step is to build the machine and conduct a two-hundred-hour test run on land. If the test runs normally, it means that this technology can be used to drive frigates. In the future, all our frigates can use this power System!" Wu Shengli was also very happy and made the decision immediately.
“Leader Wu, we don’t have this kind of STC diesel engine yet.” Wang Tianmin reminded in a low voice.
Here we are building an institution for parallel vehicles. They want to build diesel engines. Now they don’t have STC technology, so how can they experiment?
"We plan to use this kind of power for the ships we build for our customers. The diesel imported from France will arrive soon. At that time, we will find a way to disassemble the turbocharger inside and then copy it." Qin Tao said: " At the same time, as the power increases, you also need to strengthen the relevant mechanisms of the engine, such as pistons, crankshafts, connecting rods, etc."
Wang Tianmin frowned.
Chin Tao is right.
Adding a turbocharger to the engine will rapidly improve the engine's performance, but at the same time, this method of squeezing power will also cause some damage to the engine, and the relevant mechanisms need to be strengthened.
It used to be 400 horsepower per cylinder, but now if you want to increase it to nearly 500 horsepower, you need to strengthen all relevant institutions!
How to strengthen?
"You can learn from MTU diesel engine technology, and at the same time, introduce some new equipment and improve your production lines. For you, this is also an opportunity for rapid 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 cylinder will be more precise and can withstand stronger impacts. For other parts, you also need to have specialized machining centers to improve accuracy."
Low-speed diesel engines rely on their large size and do not require high strength, but this medium-to-high-speed diesel engine is different. Qin Tao put forward product upgrade requirements for them. Only in this way can they meet the needs of the four-thousand-ton frigate.
“Mr. Qin, these improvements require a large amount of funds!” Wang Tianmin looked distressed.
"You can learn from Bincheng Diesel Engine Factory." Qin Tao said: "The machine-building gods of the island country are doing research with them. With only five million U.S. dollars, they can complete the upgrade and transformation requirements for their production lines. You may also be able to Spend less, do big things.”
“But we don’t even have five 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% of cargo ships are equipped with this kind of engine.
The diesel engine factory in their old district produces medium and high-speed marine diesel engines. Most of these are used for supporting warships and the like. Currently, the domestic warship output is small. Although their factory was established during the First Five-Year Plan, But now, it’s just a matter of getting through the day.
Moreover, their factory is still in the inland area, which is incomparable with the coastal area. They can't even spend five million!
Comparing people with each other will make people angry.
“If you use the factory’s assets as collateral, borrow money from banks, and do not upgrade, you will definitely fall behind in the future and may be eliminated in the market competition,” Qin Tao said.
"Mr. Qin, it's difficult to borrow money. It's still five million US dollars, which is foreign exchange." Wang Tianmin said: "We are not as rich as your Mingzhou Shipbuilding Industry Group."
When speaking of this, Wang Tianmin suddenly remembered something: "Mr. Qin, can you provide us with money?"
Of course not, my money did not come from the strong wind, Qin Tao thought in his heart, but in order not to hurt the other person's self-esteem, he did not say it.
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 can invest in the diesel engine factory in your old district by injecting capital?" Qin Tao did not expect that there would be such a good thing as pie in the sky.
