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

"Director Zhao, why are you here, I don't know who these two are."

By the side of Director Zhao, not only followed Guo Jianjun, but also two people with glasses and looked at Si Siwenwen.

I have been here for a week, and almost every day Director Zhao will come to the workshop, and other factory leaders will also come over when there is time.

Now the factory leaders of the 663 factory have basically seen Jiang Yan.

Jiang Yan has never seen these two people once.

"Jiang Gong, these two are Minister Hong and Engineer Shen of the Shengjing Ordnance General Factory, they heard that you can repair the Jingduan machine and rushed over from Shengjing to learn, and by the way, I will give you a hand."

Shengjing Ordnance Factory is the original Shengjing Arsenal, this arsenal is very famous, it was once the largest arsenal in Asia.

In March 1948, the Joint Service General Headquarters ordered the factory to relocate key equipment and 5,000 technicians to Taiwan to establish a branch factory. On November 2, 1948, Shengjing was liberated. The Shenyang Arsenal was then taken over by the People's Government and renamed the Shengjing Ordnance Factory of the Ministry of Military Industry.

Whether it is technical strength or scale, Shengjing Ordnance Factory is much, much stronger than 663 Factory.

However, Director Zhao's words made Jiang Yan's heart a little puzzled, he had never told Shengjing Arsenal that he wanted to repair the Jingduan machine! Besides, I don't know the people in them, where they got the news.

It seems that Director Zhao saw Jiang Yan's doubts, and was a little embarrassed to explain.

"What's that, when I called Director Wu of the Shengjing Arsenal before, I casually said that Jiang Gong wanted to repair the Jingduan machine, but I didn't expect him to send someone over."

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

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

"How did you do this, how did you do it when you disassembled, how did you make sure that the wiring and parts were not damaged at all?"

Director Zhao wanted to say something after listening to Jiang Yan's words, and Engineer Shen, who was following him, looked at the parts and lines on the ground and opened his mouth first.

At this time, Engineer Shen's eyes lit up when he looked at these 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 here, the whole order will be disrupted, I have to rearrange and organize." Seeing that this Engineer Shen was about to reach out and take the parts on the ground, Jiang Yan hurriedly opened his mouth to stop it.

"Ahh I'm sorry, I'm sorry, I'm so excited, don't worry, I'm not moving, I'm just looking, looking. ”

Engineer Shen quickly withdrew his hand when he heard Jiang Yan's words, and hurriedly explained.

Then he said embarrassedly: "Jiang Gong, look, can I give you a hand." ”

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

"No problem, installation schematic, on the desk, you look at that drawing first."

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

Hearing Jiang Yan say that there were installation drawings, Engineer Shen walked directly to the table quickly, picked up the drawings and looked at them carefully.

"Are these parts cleaned with the detergent you reported, this cleaning is really clean!"

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

"Yes, these parts are cleaned to remove the dirt from them."

"Hmmm! This decontamination ability is also a little too good, if you don't look closely, you really can't tell that this is a cleaned part. ”

"Comrade Jiang Yan, you have made a great achievement, this is really a hero and a young man!"

"Minister Hong, you praised it, and I also came up with this recipe at the right time, which is just a trivial matter."

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

"Production is no trivial matter, Jiang Gong, you are just too polite."

Minister Hong was very satisfied with Jiang Yan's tone of not being humble or arrogant, and Minister Hong was very interested in Jiang Yan as a person.

After a few polite words, Jiang Yan carefully checked the tools he needed to assemble the machine for a while.

"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 this engineer Shen is a technical idiot, and he also lived in this era and became an engineer.

If this is placed in the future generations, with his character, it is estimated that the entire department or the people in the company have been offended by him.

This is a typical high IQ and low emotional intelligence.

But you can't deny that as long as you don't argue with him at work or technically, this kind of person is still quite cute. The mind is also very simple, and you won't feel difficult to get along with.

Coming back to his senses, Jiang Yan opened his mouth to explain.

"The parts and lines I marked with the triangle symbols above, I presume to be useless things."

"I suspect that it is the presence of such useless parts that causes the machine to overheat while it is running. Thus affecting the accuracy. ”

At this time, Jiang Yan's expression became serious, and he was afraid that Engineer Shen would not understand, so he pointed to the machine installation diagram in his hand and gave him a detailed explanation.

"So that's the case, I understand, it's all a trap dug for us by these capitalists."

"Jiang Gong, I won't tell you anything, we have also disassembled and assembled some foreign machine tools in private, and we have also found such problems, but you think more in detail."

"These parts you marked with question marks must be parts that you didn't judge whether they were useful or not, right?"

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

"It's not that I didn't judge it, I thought they were a group of useless gears before, and after a comprehensive analysis, I found that these three sets of gears are not useless gears, on the contrary, their existence is necessary."

Looking at Engineer Shen's puzzled expression, Jiang Yan couldn't help but explain.

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

"According to my calculations, when the machine is running to a certain temperature, there will be a set of current-switching lines to power the gears. Gear movement, will carry out a certain repair of the machine tool. ”

"Can you replace it with a large 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 came up with the idea of replacing the small gear set with a large gear set.

Jiang Yan also calculated that when the pinion set is running, there will be all kinds of problems that you don't expect, if the big gear set is replaced, this kind of problem will be completely shielded.

Moreover, the pinion set needs three pairs, and the large gear set only needs one pair to solve.

However, in order to replace the pinion set with a large gear set, this finishing machine needs to be revised and improved on a large scale.

If it is reversed, it can be rearranged and improved.

Today's department dinner, drank a little, and was a little dizzy, two chapters will be updated tonight, and the remaining chapter will be updated during the day tomorrow. Thank you all and I wish you all a happy Dragon Boat Festival.
