A nation's industrial development begins with junior engineers.

Chapter 843 Seeking advice: What is the ancestral skill of the Gallic Rooster?

Jiang Xia pulled Liu Guoqiang to the wall, pointed to the hot air duct section on the blueprint, and completely abandoned the technical terms, gesturing with his hands as he said, "Actually, it's really simple! Just find a section of old water pipe, not too thick, just like the galvanized iron pipes that our factory used to replace. Wrap it tightly around the outside of the hot air sheet duct that comes from the coal stove, like a mosquito coil."

As he spoke, he drew a spiral in the air: "Once it's coiled up, connect both ends. One end connects to a high-level cold water tank, letting the water flow down on its own; the other end leads to the sewer. The key is to add a regular gate valve to the coil's inlet pipe."

"Is that all?" Liu Guoqiang asked, his eyes fixed on Jiang Xia's gestures.

"Yeah, I guess," Jiang Xia explained.

"Next, we'll insert the thermocouple probe for temperature measurement into the hot air duct, and connect a pointer meter behind it. People don't need to keep staring at the fire; they can just look at this meter. For example, if the required hot air temperature is 65 degrees Celsius, we'll set a range, and temperatures between 67 and 63 degrees Celsius are considered acceptable."

He held up two fingers: "If the needle goes over 67 degrees, it means the fire is too strong and the hot air is too hot. At this point, open the water valve connected to the coil a little wider to let more cold water flow through the coil."

As the cold water circulates around the hot air duct, it carries away excess heat, naturally lowering the temperature of the hot air.

He bent another finger: "Conversely, if the needle drops below 63 degrees, it means the fire is weak and the air isn't hot enough. Then turn the water valve down a bit, or even turn it off temporarily, so that there's no cold water or very little water in the coil. That way, the heat from the hot air duct won't dissipate, and the temperature will slowly rise again, right?"

"Oh—!" Liu Guoqiang slapped his thigh suddenly, a bright smile of sudden realization spreading across his dark face, his eyes wide open: "I get it! So that's what it is! It's just like when we're heating the kang (a traditional heated brick bed) back home, and it gets too hot, so we lift up the mat to let some air out."

"If it gets too cold, just seal the kang (heated brick bed) opening tightly—it's the same principle! Use cold water instead of lifting the mat, and use a valve instead of sealing the opening! Brilliant! Engineer Jiang, now that you explain it, I understand completely! This method is practical! It sounds much clearer than any 'passive' or 'temperature control'!"

He rubbed his hands excitedly and exclaimed, "Wow, such a simple principle! How come we never thought of that before! We only knew how to watch the stove, adding or removing coal, working ourselves to the bone and still not being able to control the temperature. You've just wrapped a few water pipes around and added some valves, freeing people from the stove! This is the kind of method we workers should use!"

Jiang Xia nodded in satisfaction. Perfect!

The person in front of me is focused solely on understanding the fundamental operating logic and solutions of the equipment. This is what a true equipment engineer who is rooted in the front line and solves practical problems should be like!

To some, this might seem like a piecemeal approach, lacking ambition. But Jiang Xia knew that it was precisely this pragmatic, almost clumsy, dedication that was the most solid foundation for the industry.

"Got it! Engineer Jiang, I'll go get to work right away!" Liu Guoqiang heard Factory Director Wang's call from afar, turned around and ran out.

But after running two steps, he suddenly stopped and hurriedly turned back, looking somewhat embarrassed.

Pointing to the wall covered in Jiang Xia's drawings, he spoke earnestly:

"Jiang... Engineer Jiang, could... could you leave these drawings and writings on the wall for now?"

"I...I'll be done with my work in a bit, and when I get back I'd like to copy it down carefully! It's such a clear principle, I'm afraid I won't remember it just by hearing it once, I have to write it down verbatim and think about it carefully when I get back!"

Seeing the anxious look in Liu Guoqiang's eyes, as if he were afraid his precious treasure would be lost, Jiang Xia felt a warmth in her heart and smiled as she patted his arm hard.

"Don't worry! I'll keep it exactly as it is for you! This wall is yours for the next few days, feel free to copy it anytime! If there's anything you don't understand, just come and ask!"

"Thank you, Engineer Jiang!"

"You have no idea how much your plan has helped me! As soon as I finish helping my dad, I'll make a call and invite everyone from our factory over to learn from it!"

Jiang Xia then realized that the young man had previously referred to "our steel plant".

Which steel mill are you from?

"North Manchuria Steel Plant!"

Huh? It's an old acquaintance. The tungsten carbide alloy that the logistics department found earlier was made by this factory. Jiang Xia even spoke with a person in charge of this steel mill. He didn't expect to see their people here at the traditional Chinese medicine factory.

Jiang Xia watched the simple yet diligent young man leave, feeling quite gratified.

Hmm, how come at such a young age, I already have this feeling of "I have a son in my family"...

Jiang Xia shook his head, and the ahoge (cowlick) on his head stood up again.

"Busy working?"

Jiang Xia turned around, and Old Wang walked over with a serious expression.

Huh? Bro, you changed your tune pretty fast. You were just laughing at me, and now you're all set like a determined warrior?

Old Wang didn't respond. After looking around, he pulled a brown paper envelope from his inner pocket: "The old nest has sent the latest news!"

"new task?"

"No, judging from your tone, it seems like a negotiation... It's fine whether you agree or not!"

After handing the envelope to Jiang Xia, Lao Wang reverted to his cheeky self: "However, I suggest you agree to the request in the letter; there might be a surprise!"

Jiang Xia ignored him and unfolded the letter on her own. "Oh! So you've decided to send someone to the IEC General Meeting? Is this the list of attendees?"

"Huh, what the heck? Didn't they say 'participate in standardization discussions' before? How come it's now 'invited to deliver the first official address at the conference and participate in the final review of the core standard draft'?"

"Is this translation correct?"

"How could you possibly make a mistake! It's understandable if you make a mistake in English, but in French, that's impossible!"

Old Wang spoke with absolute certainty, and Jiang Xia expressed his agreement.

That's right, now that Slavic languages ​​have been introduced, the most familiar one is Gallic.

but……

What exactly are those Frenchmen up to?

"What's wrong? So what if you're the first to speak at the meeting? What's so special about that?"

"A world of difference!"

"what?"

"What's up with this French guy? Is their ancestral skill working up again?"

"what?"
