Siheyuan starts from a good life

Jiang Yan was instructing two apprentices to tighten the screws on the engine. After seeing the two people finish tightening the screws, he said: "You two, remember to tighten this screw three times, and then turn it back again."

"Xiao Jiang, why do you still need to turn the screw in circles? Isn't it better to tighten the screw more tightly? If it is enough to tighten the screw two and a half turns, wouldn't it be better to just tighten it in half?"

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

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

After listening to what Minister Zheng said, Jiang Yan thought for a moment and said, "Minister Zheng, after tightening the screw, in order to prevent it from loosening, an additional pre-tightening force should be applied, so the pre-tightening force will be eliminated after half a turn of loosening, and the screw will After tightening, it is in elastic deformation, especially under high temperature and vibration load. Such continuous pressure for a long time will cause creep. After the screw becomes plastically deformed, its strength will drop significantly or even fail. Retracting half a turn allows elastic deformation. Restore some and eliminate the pre-tightening stress at the same time. In the future, the deformation of the screw under continuous pressure will still be elastic deformation, and the probability of plastic strain and failure will be greatly reduced, allowing the screw to maintain continuous high-intensity pressure. Directly tightening it for two and a half turns is Such an effect cannot be achieved.”

As the deputy director of the First Machinery Department, Minister Zheng still knows some principles of mechanical manufacturing. When Jiang Yan said this, he completely understood the secret.

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

"No, this is what I heard from a worker master when I was studying abroad. There is such a procedure in the Hans Country operating manual."

"It seems that the technological gap between us and foreign countries is not that big. They have studied a small screw so thoroughly."

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

"What Xiao Jiang said makes sense and is very enlightened. I also believe that one day we will catch up with them." Minister Liu, who was silent next to him, also said something.

Next, Jiang Yan introduced the components to the leaders while installing the accessories on the cylinder. After a while, a complete engine appeared in front of everyone. Jiang Yan checked it and made sure it was correct.

Then he turned to the leaders who were watching and said: "Dear leaders, the engine has been tested and the engine has been manufactured and can be tested."

"Then start testing."

After hearing what the leader said, Wang Dabao, who was following Jiang Yan, brought over a bucket of gasoline and poured it in. After ignition, the engine started smoothly.

Seeing the engine starting smoothly, the workshop burst into applause.

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

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

"Thank you for your hard work, all the workers. Director Liu has prepared a celebration banquet for everyone. The department will also give some rewards as appropriate. We can't let you shed blood and tears."

"Thank you, Minister Liu." When they heard that there was a celebration banquet, the workers were naturally very happy. Although all their workers here were in mid- to high-level jobs and had good wages, you might not be able to buy it if you have money these days. All, this celebration banquet must have several meat dishes at least.

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! This is all thanks to you. Without you, this engine could not be manufactured so quickly."

After hearing what Minister Liu said, Jiang Yan replied humbly: "Minister Liu, you are serious. I just designed them. The workers who made them are the relevant workers. They are the main force."

"You little naughty boy, being modest is a good thing. Excessive modesty is a naked show off."

Minister Zheng's words made everyone burst into laughter.

"You can't be erased from the credit department. Apart from anything else, if I give you a model worker at the end of the year, you won't be able to run away. Your kid has done a lot of great things since he came back. It seems that your kid is really as hidden as Lao Luo said. It’s very deep!”

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

Hearing what Minister Liu said, Jiang Yan had no way to answer and could only smile and scratch his head.

"Xiao Jiang, can the engine you designed achieve mass production?"

Hearing Minister Liu start talking about business, Jiang Yan's face straightened, he thought for a moment and said, "According to the current plan, with sufficient supply of materials, there should be no problem in producing about 500 units a month."

"What if we expand the factory ten times? Can we achieve a monthly production of 5,000 units?"

Hearing Minister Liu's words, Jiang Yan smiled bitterly and replied: "Minister Liu, this is not a simple arithmetic problem. It involves the proficiency of workers, the manufacturing capacity of the machine and other factors, which all restrict the production of engines. "

"It seems that my expectations are a bit high. Now the entire country is lacking transportation equipment! Importing from SL will consume our already poor foreign exchange. Alas!"

After hearing Minister Zheng's words, everyone fell silent.

The country currently does not have the ability to produce cars. A large part of the cars have been seized from the enemy, and some have even reached the level of scrapping. They can only be patched up and used. It is unrealistic to import large quantities from SL for transportation. People in the Ministry of Transportation are worried a lot, and all the pressure goes to the Ministry of Machinery. The Ministry of Machinery is responsible for the country's industrial manufacturing. If the Ministry of Transport doesn't look for them, who should they look for?

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

Hearing Jiang Yan's words, Minister Zheng smiled and said: "Although I don't have much contact with you, I found that you always have such incomparable confidence in our country. We old guys with revolutionary backgrounds can't compare to you. .”

Jiang Yan had no way of answering what Minister Zheng said. Could he say that he came from a later world? Can you tell everything about the hereafter? Even if you say it, they may not believe it.

Our country has gone from poverty when it was founded to the second world economy in the world. All countries in the world think this is a miracle.

However, Jiang Yan knew the many hardships involved. Perhaps only those who have experienced it can understand the ups and downs, because no kind of success happens casually.
