Jiang Yuan stayed in Kunhai Foundry for three days, and went back to Kunhai for the time being.

The female clerk was a little disappointed when she heard it.

She had been having a good time these three days, but at this moment Jiang Yuan was leaving suddenly.

But when I heard that Jiang Yuan was only going down temporarily, when she was sure to come up in a few days, the female clerk would do it again.

Okay, next time you come up, you must stay for a few more days before leaving.

The first thing Jiang Yuan did when she returned to Jiangnan was to find Liu Yuchen, and she hurried to the laboratory of the scientific research team.

At this moment, Liu Yuchen was still busy with the design of the main board of the fully intelligent robotic arm. Seeing Jiang Yuan suddenly came, he suddenly said yin and yang strangely, "Oh, Miss Jiang, are you willing to come back?"

As soon as she heard Liu Yuchen's tone, Jiang Yuan knew that Liu Yuchen must still hold grudges.

Be careful!

Didn't I just bite you!

Besides, didn't you bite back?

It's a big deal, I'll let you take another bite!

"Yuchen, don't be angry~" Jiang Yuan hurried up and pressed her mouth up, her mouth rubbed with honey, "You definitely won't bother with me, after all, you are so beautiful, knowledgeable, gentle and generous..."

"Stop talking nonsense, stretch out your hand, and I won't be angry again with one more bite!"

"e..."

Liu Yuchen must be looking for a way to go down.

Jiang Yuan resolutely tugged up her sleeves, put it directly to Liu Yuchen's mouth, and tilted her head in the other direction, "If you are willing, then... ah!!"

Jiang Yuan screamed and subconsciously retracted her hand, only to find that there was an obvious tooth mark on her arm.

"What's there to bear!" Liu Yuchen said unceremoniously, "You bit too much harder than me!"

Jiang Yuan still wanted to say something, but after thinking about it, she was in a hurry at the time. She really tried hard and didn't make a sound. She immediately rubbed the tooth marks on her face with aggrieved expression.

After taking revenge, Liu Yuchen felt much better in his heart.

"Aren't you going to stay for a week? Why did you come back suddenly?"

Speaking of this matter, Jiang Yuan didn't care about the pain anymore. She quickly took out the notebook from her bag, put it directly in front of Liu Yuchen, and said, "Yuchen, I'm here to ask you for help!"

"what?"

Liu Yuchen picked up the notebook with a puzzled look and glanced at it, and he was naturally confused.

The drawing is messy.

"Picture! I have been observing for a long time, and I have specially drawn out the schematic diagram and design of the machine in the foundry!"

Liu Yuchen's eyes widened, and he pointed to the curved and extremely abstract drawing above, "You call this a design drawing? I can't find a straight line!"

Jiang Yuan smiled bitterly, "Let's have a look! I have never learned to draw, and my drawing skills have always been quite average."

Liu Yuchen couldn't help rolling his eyes, "Even if I look at it, I can't understand it!"

"How could you not understand?" Jiang Yuan thought Liu Yuchen was making an excuse, "Are you still not relieved, if you are not relieved, I will let you take another bite!"

Liu Yuchen was so angry that he picked up his notebook and patted Jiang Yuan, "There is a specialization in the art industry! I specialize in mechatronics! To put it simply, it is the circuit board, the motherboard, and other things, I am not professional, you are even more unprofessional, let me What am I looking at?"

"Then who should I look for?" Jiang Yuan hurriedly flipped through the notebook and said, "This is the schematic design of the Red Star II. I've been thinking about it for several days, and I feel like I have an idea, but I don't know how to implement it."

Liu Yuchen had a headache when he saw it. The drawing is curved, it is too abstract.

"Please be careful next time when you draw, you won't learn more on your own. The study materials Lao Chen gave you definitely include drawing and design!"

Jiang Yuan scratched her head awkwardly, "Forgot to read it."

have to!

Liu Yuchen had no temper at all, so he had to convene the scientific research team of No. 1 Middle School and Luo Hao's elite team of vocational high school.

In the end, the design drawing fell into Luo Hao's hands, and Luo Hao's mouth twitched when he saw it.

"Jiang Yuan, your designs are so soulful..."

"That's it!" Jiang Yuan raised her eyebrows and said happily, "Luo Hao, do you understand?"

"Reluctantly, I'll restore it first, you haven't written many parameters on this..."

"It's okay, I remember it!"

Luo Hao started to do the second drawing work. If you don't know the parameters, just ask Jiang Yuan.

Jiang Yuan really remembered it clearly. Seeing that Luo Hao started to restore the design plan in a neat manner, Jiang Yuan felt surprised, "You went to a vocational high school here, and it was quite professional!"

"It's just basic shit."

Luo Hao drew carefully, and it took nearly half an hour to restore the drawing.

Large-scale equipment, even if it is something eight years ago, is extremely sophisticated in design. At first glance, it is complicated and complicated.

After all, there was no formal contact, and Jiang Yuan continued to explain various working principles with everyone.

Because this large-scale device itself belongs to the product of industrial integration, there are many disciplines and types involved.

Even a small screw has its specific function.

One missing part can go wrong.

The scientific research team and the vocational high school team also found their own areas of expertise.

Luo Hao learned the most complicated things, and his comprehension was relatively strong. With Jiang Yuan's explanation, he could almost imagine the overall structure in his mind.

"So, what's your purpose? Improvement?"

Jiang Yuan nodded slightly, holding Luo Hao's design drawing and began to gesture.

"The first is the drive shaft here. Now both the German and Japanese systems use fully automatic input ports, and hydraulic ones like this have basically been eliminated. I thought about it, is it possible to use electric power to improve efficiency, Red Star Twelve is electric now, wait for me to find it for you..."

Jiang Yuan began to pick up the phone again and rummaged for a while, and when she found it, she gave everyone a look.

Luo Hao pondered while holding his chin, and shook his head, "It's not feasible."

After speaking, Luo Hao picked up the pencil and started to draw the line.

"The devices linked here are here...here...and here..."

Luo Hao drew a very long line in one breath, almost running through the linkage devices of half of the equipment. , this machine may also be damaged, this is the final product of industrial integration, how can it be so simple to modify and upgrade."

This time, Jiang Yuan poured a large pot of cold water on Jiang Yuan.

However, Li Yunyuan, a vocational high school student, suddenly took a pencil and drew a circle at the input port. "The hydraulic efficiency is slow, but the bearing force is strong. You can try to increase the input amount, which can also improve the efficiency."

Luo Hao thought about it carefully, and couldn't help but nodded, "It's an alternative, Jiang Yuan, what is the input limit?"

"The maximum limit at one time should be 20 tons, but what I saw in the factory was only 15 tons at most. The operator said too much, it is easy to cause problems, and it has to be repaired frequently."
