At this time, Gao Yong also said: "You kid is really a pit, you actually dig a pit on the engine, if others repair, don't know the situation, once it is disassembled, it is finished, and it cannot be installed directly, once it is polished or something, the performance cannot be guaranteed." If you design it like this, if it breaks, how do you let others fix it? ”

Li Zhao was a little strange, and said with a look of a fool: "Did you forget your brain at home today, isn't it an easy question?" With liquid nitrogen, we have a large number of liquid nitrogen by-products in the rolling mill, and when we are repaired, we directly use liquid nitrogen to cool it, and it will not be here at minus 1200 degrees? Why do you still need to ask? ”

"Isn't that common sense that we learn? Why did you forget about this, shouldn't you? And this is not a pit, the machining accuracy can only reach the current level, I don't want to do it, the vibration, the noise is too big. If the machining accuracy can be improved by a big grade, there is no need to toss so much if you want to reach the current level, of course, if the machining accuracy can be improved by another grade, I will design the others, it is not like this. ”

After listening to Li Zhao's words, Gao Yong was a little stupid, and said: "I found that it was a mistake for me to come to see you, you guy is too pit, how did you come up with such a pit design, our factory has been studying for more than a month, and after it was dismantled, everyone was helpless and couldn't install it." You actually designed the installation temperature of the parts are different, good guy, do you want to design the installation temperature of each part differently in the future? ”

When Li Zhao heard this, he also smiled and said, "That's not it, but under normal circumstances, it is relatively normal to divide into three types of temperatures." In fact, this design is the trend of the times, the equipment will become more and more sophisticated in the future, so that the design can more effectively solve the vibration, noise and the like, don't you find that now the engine vibration and noise have been reduced, and the speed has increased. ”

Gao Yong continued: "Of course I found it, I found these, so I dismantled it, and after dismantling, I couldn't install it on the drawings." This division headquarters has a telephone, I will call the factory, tell them about the situation, let them stop pondering, just give them the answer, they actually need to use liquid nitrogen to cool. No, if liquid nitrogen is used, it is still possible to install a small amount, and if it is a large amount, it will be troublesome? ”

Li Zhao was speechless at this time, so he said: "What have you experienced during this period of time, this brain seems to have really forgotten home, cold storage, anyone can still use liquid nitrogen." Then Li Zhao just stared at Gao Yong.

Gao Yong said that in the future, it will not be fully realized, after all, in the future, only some equipment with very high requirements for installation accuracy will be cooled with liquid nitrogen, and most of the low-temperature installation will be carried out in cold storage, but the temperature will be lower, generally reaching below minus 60 degrees, which is the limit of the current military factory.

And Liu Ming on the side also said: "Yes, Gao Yong, I found that you really seem to have a problem, you don't know how to study armor, and finally put armor on your brain, right?" This reaction is slow enough, what have you been through? ”

At this time, Gao Yong also scolded with a smile: "Go and go, what's the problem, it's just that I was stimulated by Li Zhao, don't you know that our factory is going crazy, ask the military factory here, no one is willing to say it, and what we say must be kept secret." For a period of time, I have been studying this, and a lot of research has been delayed. I've also been forced by this drawing and parts for a while, and that's all I have in my head. ”

Li Zhao was also speechless, but it was understandable to think about it, after all, someone else had made something in front of him, and he couldn't put it up according to the drawings after dismantling it, how could he not be crazy. You must know that they are usually comparable factories, and suddenly you seem to have opened up the second line of Ren Du, and you still treat me like a fool, and everyone has to worry about them. It was far enough not to hit the door directly, and both sides were competing.

However, Liu Ming said beside him: "Li Zhao, your design is indeed amazing, if you don't say it yourself, we just want to break our heads, and we don't know, it's really a good way to keep it secret." In the future, if you come up with a design with a different installation temperature for each part, then you don't have to keep it secret, and others can't copy it. ”

Li Zhao is also full of black lines, who can be so boring, and the temperature of each part design is different, isn't this asking for trouble for himself? How can this kind of installation be efficient? So he said: "If you design it this way, how can you guarantee the installation efficiency?" It's already quite cumbersome to install like this, and it's difficult to increase production. ”

Hearing Li Zhao say this, the two also nodded, indeed, now each part needs to be taken separately, and it is more difficult to mention the efficiency, not to mention that each part uses a different temperature. At this time, Gao Yong also asked: "Can you tell me the installation temperature of this engine?" I'll call back later. ”

Of course, there is no problem with this, Li Zhao also said that those parts need to be heated and those need to be cooled, and at the same time said: "Considering the temperature over there, you had better cool down the parts that need to be cooled with liquid nitrogen, otherwise it will be difficult for you to find a place where the temperature can be reduced to minus seventy or eighty degrees." ”

Soon several people came to the division headquarters, and Li Zhao also took the two to find Division Commander Zhang's office, where Division Commander Zhang was drinking tea. It's still Master Zhang who is leisurely, since Father Su came, he is idle. After meeting and greeting Division Commander Zhang, Li Zhao first introduced the two of them: "This is my Uncle Zhang, the commander of this division." ”

The two also hurriedly followed Li Zhao to call Uncle Zhang, and Li Zhao also introduced the two to Master Zhang, after the introduction, Li Zhao asked Gao Yong to call by himself, and he pulled Liu Ming to sit down and drink tea, and finally connected the phone after waiting for a long time.

I heard the other side say: "Xiao Gao, didn't you go home for vacation?" Where did you find the phone, and you actually called me, I don't know if I'm busy right now? The voice on the other side could be heard with a sense of fatigue.

At this time, I heard Gao Yong say: "Chief engineer, I have met the engine designer, and I will tell you a good news, the designer is not from the military factory, but from other factories." And the engine installation method, our idea is right, that is, our temperature is not low enough, they require that there is a temperature difference of about 70 degrees between the low temperature part and the part that does not cool down, and the oil bath for those parts heated is also right, in general, we have found a way. ”

I heard the other side ask: "Okay, this is good news, I have been laughed at by them for more than a month, good guy, it turns out that the designer is not in their factory, wait for them to take revenge in the future, and I will never let them go." ”

After talking for a while, he asked, "Did you ask, what did they use to lower the temperature, and how did they lower the temperature so low?" Now our temperature is minus twenty or thirty degrees, isn't it going to drop to minus eighty or ninety degrees, this temperature is too low, we don't have any equipment, it is difficult to reach this temperature. ”

Li Zhao was speechless, he was actually the same as Gao Yong's thinking, could this idea still be contagious? Gao Yong didn't dare to delay, and hurriedly said: "I asked, they use cold storage and room temperature workshop to cooperate, and now the assembly workshop is heated." There are three kinds of temperatures, one is the oil bath, one is called normal temperature, 25 degrees, and the other is low temperature, below minus 40 degrees. I also asked about our current situation, and he told us to cool the parts with liquid nitrogen. ”

At this time, I heard the other side shouting: "Yes, I'm so stupid, why didn't I think of it." Okay, I know, Xiao Gao, you have made a great contribution this time, the deputy chief of the technical department is yours, and you can get promoted when you come back. I'll hang up first, now go to the test immediately, you can go home and have a good rest, and come over early after the New Year. ”

At this time, he hung up the phone directly, and everyone who watched looked at each other, it was really an urgent child, but I don't know what time this person will work overtime today, and it is estimated that it is likely to be eleven or twelve o'clock. Today, it is necessary to successfully assemble the equipment and then try the machine before giving up, which is already the norm for these researchers.

Seeing that he had already made a call, Li Zhao said: "Uncle Zhang, my two classmates have just come back, and I plan to pick them up today, do you want to go together?" Today, I went to the restaurant and went to eat mutton, which is a rare opportunity. ”

Master Zhang said at this time: "Forget it, what am I going to do when you young people gather, and you are talking about technology, and I can't interject, and you are not comfortable when I go, and you have to take care of my feelings." Now that I'm fine, I'll find your father-in-law to have a drink, but it's much easier than you, and if you have nothing to do, you can let Chief Engineer He cook, but it's no worse than you going to eat mutton, and it's more comfortable than you, you don't dare to talk casually there, right? ”

Li Zhao heard this, and also said: "You will still enjoy it, but they just came back, and if you don't take them to a big meal, you really don't want to go, so I won't bother you, I'll drive away, it will take two days." ”

After speaking, he took the two of them to drive, chose a car with full gas, and registered the two of them at the doorman, and the three of them went straight to the newspaper office, and when they saw the newspaper, Liu Ming called directly: "You won't chase after Colonel Su, right?" I remember that in our school, the journalism department, it seems that the university of Su stayed in our newspaper office in the capital, and it is said that he came here because of his connection. You seemed to be eyebrow-raising when you were in school, wasn't she? ”
