Siheyuan starts from a better life

Chapter 137, Conversation

Jiang Yan was instructing two apprentices to screw the engine.After seeing two people screwing the screw, he said: "You two, remember to screw this screw three times, and then turn it around."

"Little Jiang, why do you have to turn around? Isn't it better to tighten the screw as tight as possible? If it's enough to twist it twice and a half times, wouldn't it be better to simply twist it in half?"

Before the two apprentices could speak, a voice of consultation came from behind Jiang Yan.

After hearing this voice, Jiang Yan turned around and saw a large number of leaders appearing behind Jiang Yan, including Liu Xufeng, Minister Liu and Minister Zheng, and the person who was asking the question was Minister Zheng.

After listening to Minister Zheng's words, Jiang Yan thought for a while, and then said: "Minister Zheng is like this. After the screw is tightened, in order to prevent loosening, an additional pre-tightening force should be applied. Therefore, the pre-tightening force will be eliminated after loosening half a turn, and the screw will be tightened. After being tightened, it is in elastic deformation, especially under high temperature and vibration loads. Such continuous pressure will cause creep for a long time. After the screw becomes plastically deformed, its strength will be greatly reduced or even fail. Backing off half a circle is to allow elastic deformation Restoring a little bit and eliminating the pre-tightening stress at the same time, the deformation of the screw under continuous pressure will still be in elastic deformation, and the probability of plastic strain and failure will be greatly reduced, so that the screw can maintain a continuous high-strength pressure, and it is directly screwed two and a half times. It can’t achieve that effect.”

As the deputy minister of the Ministry of Machinery, Minister Zheng still knows some principles of mechanical manufacturing, and Jiang Yan fully understands the tricks when he says this.

"You came up with this yourself." Minister Zheng asked.

"No, this is when I was studying abroad and I heard a worker master say that there are such procedures in the Hans Country's operation manual."

"It seems that the technology gap between us and foreign countries is not so big. Even a small screw has been studied so thoroughly."

After listening to Minister Zheng's words, Jiang Yan said: "Minister Zheng, although the gap between us and them is relatively large, I always believe in our country and people. I believe that one day, we will catch up and let other countries never again. Don't dare to underestimate us."

"Xiao Jiang's words are reasonable and very enlightened. I also believe that one day we will catch up with them." Minister Liu, who was silent next to him, also interjected.

Next, Jiang Yan introduced the parts to the leaders while installing those accessories on the cylinder. After a while, a complete engine appeared in front of everyone's eyes. Jiang Yan checked it to make sure it was correct.

Then he turned his head and said to the surrounding leaders: "Leaders, the engine has been tested and the engine has been manufactured and can be tested."

"Then start the test."

Hearing the leader's words, Wang Dabao, who was next to Jiang Yan, brought over a barrel of gasoline and poured it in. After ignition, the engine started smoothly.

Seeing the smooth start of the engine, there was applause in the workshop.

At this time, Department Liu said to all the workers: "The successful manufacture of the engine is a milestone, which lets foreigners know that what they can do, we can still do."

As soon as he finished speaking, there was another round of applause in the workshop.

"All the workers and masters have worked hard. Director Liu has prepared a celebration banquet for everyone, and the department will give some rewards as appropriate. You can't shed blood and tears for all heroes."

"Thank you, Minister Liu." The workers were naturally very happy when they heard that there was a celebration banquet. Although all the workers here are middle-level and high-level jobs, and the salary is not bad, but you may not be able to buy it if you have money these days. Du, at least there must be a few meat dishes in this celebration banquet.

After coming out of the workshop, Jiang Yan followed the leaders to the conference room.

After everyone sat down, Minister Liu spoke first, "Xiao Jiang! It's all thanks to you. Without you, this engine couldn't be manufactured so quickly."

Hearing Minister Liu's words, Jiang Yan replied modestly: "Minister Liu, you are serious. I just designed them. They are made by relevant workers. They are the main force."

"You little cunning, modesty is a good thing, excessive modesty is blatant showing off."

Minister Zheng's words caused everyone to roar with laughter.

"Your credits can't be erased in the Ministry of Merit. If nothing else, you won't be able to run away if you are given a model worker at the end of the year. Your boy has done a lot of great things since he came back. It seems that you are really hiding as Lao Luo said. It's very deep!"

"You kid, tell me the truth. If you have any skills, you can't hide them from us in the future. If you have the ability, just show it. We will set up a stage for you to sing."

Hearing Minister Liu's words, Jiang Yan made Jiang Yan have no way to answer, but could only scratch his head with a smile.

"Little Jiang, can the engine you designed achieve the purpose of mass production?"

Hearing Minister Liu started to talk about business, Jiang Yan straightened his face, thought for a while and said, "According to the current plan, if the supply of materials is sufficient, it should be no problem to produce about [-] units a month."

"What if we expand the factory tenfold! Can it reach a monthly output of [-] units?"

Hearing Minister Liu's words, Jiang Yan replied with a wry smile: "Minister Liu, this is not a simple calculation problem, it involves the proficiency of workers, the manufacturing capacity of machines and other factors, which restrict the production of engines. "

"It seems that my expectations are a bit high. Now the whole country lacks transportation equipment everywhere! Importing from SL will consume the foreign exchange that we were not rich in. Sigh!"

Hearing Minister Zheng's words, everyone fell silent.

The country does not have the ability to produce cars now. A large part of the cars are seized from the enemy, and some have even reached the scrapping standard. They can only be sewn and mended. It is unrealistic to import a large number of cars from SL. The people in the Ministry of Ability and Communications are not less worried, and all the pressure is on the Ministry of First Machinery.The Ministry of First Machinery is responsible for the national industrial manufacturing, and the Ministry of Communications will not find them.

Seeing everyone's silence, Jiang Yan said: "All of this must be resolved. At present, we have produced a suitable engine, and we will not be far away from producing a car. One day, we will be the ones running on the roads of our country. We no longer have to worry about insufficient capacity for the cars we manufacture.”

Hearing Jiang Yan's words, Minister Zheng said with a smile: "Although I don't have much contact with you, I found that you always have such incomparable confidence in our country. We old guys who are born in the revolution are not as good as you .”

Jiang Yan couldn't answer what Minister Zheng said. Can he say that he is from the later world?Can you tell everything about the future generations?Even if it is said, they may not necessarily believe it.

All countries in the world think it is a miracle that our country went from being poor and white when it was founded to becoming the second world economy in the world.

But Jiang Yan knows the hardships in the process, perhaps only those who have experienced it can understand the ups and downs, because there is no kind of success that happens casually.
