Chapter 301 Cooperation
"Old Liu, why do I feel that your design is plagiarizing our idea?" Lin Zhenhua sat down and whispered to Liu Xianghai.

Liu Xianghai's mind was full of black lines: "Xiao Lin, you can rely on some clues to talk nonsense. We are engaged in thrusters, and you are a seller of electric fans. How can we stand up to it?"

Lin Zhenhua said: "Old Liu, I don't just sell electric fans, I also sell washing machines. Our waterfall washing machine uses the principle of water spraying. How do I think your water spraying pump is the same as the pump in our washing machine?" code thing."

Liu Xianghai couldn't help laughing: "If you want to say this, it's really the same thing. To tell you the truth, we started to develop water jet propulsion, and after finishing the waterfall washing machine for you, we often proposed this plan to the institute. To a certain extent, it should be inspired by you."

"Here's the patent fee." Lin Zhenhua smiled and stretched out a hand.

Liu Xianghai patted Lin Zhenhua's hand lightly, and said, "Pull it down. The water jet propulsion method was invented by the British Toogood and Hayes as early as the 17th century. However, the earliest water jet propulsion The outboard motor was invented by the Americans in 1946. In 1962, the Soviet Union first used three-stage axial flow pumps and two-stage axial flow pumps. When I was studying in the Soviet Union, I also came into contact with these things.”

"It has such a long history?" Lin Zhenhua was depressed.When he first heard Chang Qingbo talk about water jet propulsion, he was a little excited, thinking that he inspired Chang Qingbo and led to the emergence of a new technology.Now it sounds like there is nothing wrong with me.

"It should be said that you, Xiao Lin, still have credit." Liu Xianghai comforted, "If you hadn't given 50 to lure Lao Chang to study the sprinkler system, they wouldn't have turned to this direction so quickly. Don't be a fool. Look at the axial-flow water jet propulsion pump in this picture now, if it is done well, our country's high-speed ships will depend entirely on it."

The two of them were whispering here, while Chang Qingbo was already introducing the technical issues of the water jet pump over there.The principle of the water jet pump is not too complicated. The propellants are all engaged in this direction, and the theoretical design has been completed.However, in terms of processing technology, the problem is relatively serious, so Liu Xianghai summoned Lin Zhenhua and his party to Shanghai from a long distance.

"We have no experience in the manufacture of this kind of pump equipment. Director Liu said that Hanhua Heavy Industry has experience in producing pump equipment, so please come over and give us some guidance." Chang Qingbo said politely Said.

Several people from Hanhua Heavy Industry looked at each other, and Zhou Houcheng spoke first: "The shape of the cavity of your pump is too complicated, and the internal finishing is very difficult. I don't have much confidence in doing it."

Peng Gang said: "Some processing work must be done with CNC machine tools, but it must also be equipped with special tooling, and several sets of combined fixtures must be designed. If only one or two pieces are made, the cost will be too high."

"Special tools are also required for installation. I think the installation of this shaft needs to be done using hydraulic sleeves. It must have a special high-pressure oil pump and diffuser. It may be difficult to install it with ordinary tools." Sun Changyuan started from a fitter Viewpoints are also provided.

"In terms of materials, what are your considerations? The requirements for wear resistance and corrosion resistance of the cavity should be very high?"

"If you design a set of control software separately, the processing efficiency should be greatly improved, but can you meet the requirements of mass production at present?"

"..."

Everyone started talking one by one. At first, everyone was a little cautious, afraid that what they said would be inappropriate. Later, the more they talked, the more they got into the mood, and they threw the timidity out of the sky.These workers and technicians are all skilled and have made some achievements in their own fields. What they said made the technicians of the propulsion institute feel refreshed.Slowly, Chang Qingbo and others also joined the discussion, and the conference room was full of voices and excitement.

"Director Liu, the masters have said so well, they have solved a lot of our confusion." Chang Qingbo squeezed out from the crowd, walked in front of Liu Xianghai and Lin Zhenhua, and said happily.

"How about it, are you sure you can make a prototype?" Liu Xianghai asked.

Chang Qingbo said: "If these masters can give us some guidance, I think we can produce the prototype."

"How long will it take?" Liu Xianghai asked.

"I guess... it will take a month or two. Of course, we can work overtime, but I don't know if it is appropriate for the masters to work overtime." Chang Qingbo said.

"A month or two? Still working overtime?" Liu Xianghai frowned.

Chang Qingbo said: "This is impossible. The structure of the whole pump body is very complicated, including turning, milling, boring, grinding, clamping and other processing methods. That master Peng said that if he can do some With special tooling, some operations can be greatly simplified, and the progress can be accelerated a lot.”

The so-called tooling is a general term, meaning all kinds of process equipment used in the manufacturing process, including cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter tools, station equipment, etc.Special tooling refers to equipment specially designed for a particular product, which can make some work in the manufacturing process easier.

For example, if there is a 10mm round hole on the workpiece to be processed, if the worker uses a caliper to measure it after each processing, he needs to measure many times at different positions, which is very troublesome.If you can make a cylindrical plug gauge with a diameter of exactly 10 mm, then you only need to plug the plug gauge into the hole to check the degree of fit when measuring, which can greatly reduce the workload of measurement.This kind of customized plug gauge belongs to special tooling.

Under the condition of one-piece production, it is uneconomical to use special tooling.But if the production batch is large, using special tooling can greatly reduce the cost, and at the same time make the production quality more stable.

Chang Qingbo's entanglement lies in whether to make special tooling for this water jet pump.

"Then do it." Lin Zhenhua interjected, "If a worker wants to do a good job, he must first sharpen his tools. Don't you just want to make a pump like this?"

"Of course not." Liu Xianghai said, "If our propulsion pump is successfully trial-produced, it can be installed on missile speedboats, patrol boats, reconnaissance boats and other ships in the future. It has a wide range of uses, and it is entirely possible to meet the requirements of mass production."

"If this is the case, then it is worth getting a set of special tooling." Lin Zhenhua said.

Liu Xianghai smiled wryly and said: "Xiao Lin, you are the big boss now, you are rich and powerful, and you don't hurt your back when you talk. How can we have so much money to buy special tooling? Do you know why I ask you to help us, because we need to go to the big boss for this kind of work? The factory, people are not willing to accept it at all."

"No way?" Lin Zhenhua said, "Didn't you make a lot of money by helping you sell the frigate last time? I heard that you did a few more deals later, and the profits should be good, right? Why, I let you give all the money. Spent it?"

Liu Xianghai said: "There are more wolves and less meat. Our navy has a lot to do. The little money we earn from selling warships is enough to maintain the daily operations of various research institutions. Water jet propulsion pumps, if you want to Mass production requires a brand new manufacturing system, how can we afford it.”

Lin Zhenhua nodded. He and Liu Xianghai sat on the side of everyone's discussion just now, and they both listened to it clearly. They knew that it would take a huge amount of money to invest in such a water jet propulsion system.First of all, a full set of processing equipment is required, including various vertical and horizontal lathes, milling machines, boring machines, and grinding machines, some for rough machining and some for finishing.Secondly, it is the production or purchase of special tooling, some of which are expensive.Finally, in fact, the materials and heat treatment process of the whole equipment have not been solved. To solve these problems, a lot of experiments need to be done, and the money spent is not less than the purchase of equipment.

If the thruster institute only intends to manufacture a set of such water jet propulsion pumps, everything can be kept simple, and such an example also has.In the 50s, when China imitated the engine of a Mercedes-Benz car, it could not pass the precision casting first.The final solution is to cast dozens of cylinder blocks according to the shape, and then pick the one with the closest size, and use a file to file it little by little until it completely matches the prototype.It is said that the performance of the engine produced in this way is almost the same as that of the original one.

Relying on this method, the Chinese have made many amazing products in the early years, and they are worshiped on the Internet in later generations as they have mastered so many core technologies.In fact, this is not the method of large-scale industry at all, but more like the method of handicraft workshops.Craftsmen can carve the contents of a dream of Red Mansions on a strand of hair, but you must not think that this means that China has mastered precision manufacturing technology, because it is not the same thing at all.

"Old Liu, according to what you said, you called us here because you wanted us to make a set of water spray pumps for you with the method of gnawing bones by ants, and you took them to the central government to say goodbye, and then threw them into the garbage dump. Rusted inside?" Lin Zhenhua said half-jokingly.The so-called ants gnawing bones is the kind of manual method mentioned above. If you use a file to file, you can always make things out.

"Not at all." Of course Liu Xianghai understood what Lin Zhenhua was referring to. He admitted in his heart that Lin Zhenhua's words were correct, but he couldn't say that: "What do you mean to announce the good news to the Central Committee? We just want to verify the feasibility of water jet propulsion." , with this set of water jet pumps, we can obtain a lot of first-hand data and accumulate a lot of experience. As for mass production, it is indeed difficult at present. In the next five to ten years, I hope the country will spend money to do this. A production system is unrealistic.”

"Old Liu, what do you think if I pay for it?" Lin Zhenhua said.

"You pay?" Liu Xianghai was taken aback, he didn't understand Lin Zhenhua's intention.

"Of course I didn't pay for it myself." Lin Zhenhua said, "Our Hanhua Heavy Industry paid for it. I just did a rough calculation. It would take about 1000 years to buy a full set of processing equipment, make tooling, and add the most basic materials and heat treatment experiments. About [-] million, of course this is only the initial investment. We should be able to get this money out.”

"My estimated result is about the same as yours." Liu Xianghai said, "This amount of money is a huge sum of money for our propulsion station. Of course, it may not be a big deal for you Hanhua Heavy Industry .However, why do you pay this money? You don’t mean that you are enthusiastic about national defense and are willing to share the country’s worries, right?”

Lin Zhenhua raised his eyes and said, "Old Liu, why can't I worry about the country? Don't I look like an ambitious young man?"

Liu Xianghai said with a smile: "You do, but I don't believe it. Ten million yuan is not a small amount. You said that you are willing to pay hundreds of thousands, but I still believe it. If you take out ten million yuan at once, there will be no return. It really doesn't look like a business. Don't say whether you will do this, even if you do, I dare not ask for it."

Lin Zhenhua said: "No, I am willing to pay the money because I see the rewards. Lao Liu, my idea is this. You provide the technology, and Hanhua Heavy Industry will provide the money, including the workers. Let's make a What do you think of a joint venture to jointly produce water jets?"

"I'm afraid this is a bit difficult." Liu Xianghai said, "Enterprises want to make profits, and the Navy will not have enough orders in the next few years. Even if this enterprise can be established, it must be a loss-making enterprise."

Lin Zhenhua said: "Why are you only looking at the order of the navy? I have just heard that your water jet propulsion system can be used on civilian ships, including transportation boats for offshore drilling platforms, inland river patrol boats, High-speed passenger ships and so on. After a few years, when we have money in China, we can also engage in yachts. This must be a huge market.”

Liu Xianghai waved his hands again and again: "Xiao Lin, you're just being wild. We are a military enterprise, so how can we make civilian products? Our technology is kept secret."

"You pull it down." Lin Zhenhua said disdainfully, "Old Liu, let's not deceive ourselves. You said it yourself, the Americans started to develop water jet propulsion technology in 1946, and the Soviets also had a finished product in 1962. , who are you going to keep this bit of technology secret from?"

"This..." Liu Xianghai looked depressed, Lin Zhenhua's words were a bit blunt, but they were indeed correct.Many of China's military technologies are hidden every day by myself, for fear of being known by others.In fact, their technology is far more advanced than ours, so the value of this kind of secrecy is really not too great.

"Old Liu, this matter is actually very easy to handle. We will cooperate to build a factory, and your people will be responsible for the confidentiality of the technology. We will only use it for the military when it comes to cutting-edge technology. For things that are not very confidential, we will For civilian products. In this way, military products can be developed better by subsidizing military products with profits from civilian products. What do you think?" Lin Zhenhua said in a persuasive manner.

"Little Lin, you always give me problems." Liu Xianghai pointed at Lin Zhenhua's nose and said, but judging from the expression on his face, it was clear that Lin Zhenhua's words had moved his heart a little.
