Siheyuan starts from a good life

At this time, Jiang Yan, who was looking at the drawings, put down the drawings in his hand and stepped forward to meet him.

"Director Zhao, why are you here? I wonder who these two are."

Next to Director Zhao, not only Guo Jianjun, but also two people wearing glasses and looking polite.

I have been here for a week. Factory Director Zhao comes to the workshop almost every day, and other factory leaders also come when they have time.

Now Jiang Yan has basically met all the factory leaders of the 663 Factory.

Jiang Yan had never seen these two people before.

"Gong Jiang, these two are Director Hong and Engineer Shen from the Shengjing Ordnance Factory. They heard that you can repair the fine segmentation machine and came over from Shengjing to learn from it. They also gave you a hand."

Shengjing Ordnance Factory is the original Shengjing Ordnance Factory. This arsenal is very famous. It was once the largest arsenal in Asia.

In March 1948, the Joint Service Headquarters ordered the factory to relocate key equipment and 3 technicians to Taiwan to establish a branch. Factory director Chen Xiuhe resisted and delayed implementation with excuses. On November 5000, 1948, Shengjing was liberated. The Shenyang Arsenal was taken over by the People's Government and renamed the Shengjing Ordnance Factory of the Ministry of Military Industry.

In terms of technical strength or scale, the Shengjing Ordnance Factory is much stronger than the 663 Factory.

However, Director Zhao's words made Jiang Yan a little confused. He had never told Shengjing Arsenal that he wanted to repair the fine segment machine! Besides, I don’t know anyone among them, so where did they get the news from?

It seemed that Director Zhao noticed Jiang Yan's doubts and explained a little embarrassedly.

"What about that? When I called Director Wu of the Shengjing Arsenal, I casually mentioned that Mr. Jiang, you wanted to repair the fine segment machine. I didn't expect him to send someone over."

"How's it going, Mr. Jiang, are you ready to start assembling?"

"We are preparing, and we will start assembling it after the parts are tested again and there are no problems."

"How did you do this? How did you ensure that the circuits and parts were not damaged at all during the disassembly?"

After hearing what Jiang Yan said, Factory Director Zhao wanted to say something more. Engineer Shen, who was following him, looked at the parts and circuits on the ground and spoke first.

At this time, Engineer Shen's eyes were shining as he looked at the newly cleaned parts on the ground, as if he had seen a stunning beauty.

"Don't move. These parts are placed in order. If you move, the whole order will be disrupted. I have to rearrange and organize it." Seeing Engineer Shen reaching out to pick up the parts on the ground, Jiang Yan Quickly speak up to stop it.

"Ah! I'm sorry, I'm sorry, I'm so excited. Don't worry, I won't move. I won't move. I just have a look."

Engineer Shen quickly stopped when he heard Jiang Yan's words and hurriedly explained.

Then he said sheepishly: "Jiang Gong, see if I can give you a hand."

When he said this, his eyes were full of expectation.

"No problem, the installation diagram is on the desk. You should take a look at that drawing first."

After Jiang Yan agreed, he pointed to the installation diagram on the table and said something.

After hearing Jiang Yan say that there were installation drawings, Engineer Shen walked quickly to the table, picked up the drawings and read them carefully.

"Are these parts cleaned with the detergent you reported? They are so clean!"

Minister Hong, who was squatting there, looked at the old parts that had been cleaned and asked Jiang Yan.

"Yes, these parts have been cleaned with detergent to remove dirt."

"Yeah! The decontamination ability is also very good. If you don't look carefully, you really can't tell that these are cleaned parts."

"Comrade Jiang Yan, you have done a great job. This is truly a hero born from a boy!"

"Minister Hong, you are so complimentary. I came up with this recipe just in time. It's just a small thing."

Jiang Yan actually didn't care about Minister Hong's praise.

"Nothing is trivial in production, Mr. Jiang, you are just too polite."

Minister Hong was very satisfied with Jiang Yan's neither humble nor arrogant tone. Minister Hong was very interested in Jiang Yan.

After being polite, Jiang Yan carefully checked the tools he needed to assemble the machine.

"What do the triangle symbols on these drawings mean?"

Engineer Shen suddenly appeared behind Jiang Yan with the installation drawings, startling Jiang Yan who was making preparations.

It can be seen that Engineer Shen is a technology geek. He lived in this era and became an engineer.

If this were to be seen in future generations, with his character, everyone in the entire department or company would probably be offended by him.

This is a typical case of high IQ and low EQ.

But you can't deny that as long as you don't argue with him about work or technology, this kind of person is still quite cute. They are also very simple-minded, and you won't find it difficult to get along with them.

After coming back to his senses, Jiang Yan opened his mouth to explain.

"The parts and circuits I marked with triangle symbols above are, I presume, useless."

"I suspect that it is because of the existence of such useless parts that the machine will overheat when it is running. This will affect the accuracy."

At this time, Jiang Yan's expression became serious. He was afraid that Engineer Shen wouldn't understand, so he pointed at the machine installation diagram in his hand and explained it to him in detail.

"So that's it. I understand. This is a trap dug for us by these capitalists."

"Gong Jiang, to tell you the truth, we have also disassembled and assembled some foreign machine tools in private, and we have also discovered such problems, but you think about them in more detail."

"These parts you marked with question marks must be parts that you haven't judged whether they are useful, right?"

Engineer Shen pointed to a set of gears on the drawing and asked. Next to this set of gears, Jiang Yan drew a question mark.

"It's not that I didn't judge. I thought these three sets of gears were useless gears before. After a comprehensive analysis, I found that these three sets of gears are not useless gears. On the contrary, their existence is very necessary. .”

Seeing Engineer Shen's confused expression, Jiang Yan couldn't help but explain.

"Gong Shen, you see, the purpose of these three sets of gears is to debug the machine tool, not to have any effect on the operation of the machine tool."

"According to my calculations, when the machine reaches a certain temperature, there will be a set of current exchange circuits that supply power to the gears. When the gears move, the machine tool will be repaired to a certain extent."

"Can it be replaced with a larger gear set?" After hearing Jiang Yan's explanation, Engineer Shen thought for a while and put forward his own opinion.

Jiang Yan was surprised by his opinion! In such a short period of time, he actually thought of replacing the small gear set with a large gear set.

Jiang Yan had also calculated that when the small gear set was running, various unexpected problems would occur. If the large gear set was replaced, such problems would be completely eliminated.

Moreover, the small gear set requires three pairs, while the large gear set only requires one pair.

However, if you want to replace the small gear set with a large gear set, this precision section machine will need large-scale modifications and improvements.

If you reverse imitate, you can rearrange the layout and improve it.

The department had a dinner today. I drank a little and felt a little dizzy. I will update two chapters tonight and the remaining chapter will be updated during the day tomorrow. Thank you all and wish you all a happy Dragon Boat Festival.
