Chapter 842 There are always honest people out there!
Cheng Gui, the young girl, took out her fountain pen and waved it in front of Jiang Xia: "Are you really sure this is it?"
"OK!"
"Select a 0.5 mm diameter pen nib, shorten the pen barrel, and weld it onto a 6 mm thin copper tube."
Jiang Xia shifted his position and drew a Y-shaped pipe diagram on the wall: "The copper pipe splits into two lines, one connecting to the extract storage tank and the other to compressed air. Utilizing the Venturi effect, the compressed air will 'suck' the extract out, forming droplets of about 50 micrometers, finer than a hair, so it won't clog..."
The presentation is clear, the principles are well-defined, and the explanation is concise.
However, an eerie silence fell over the scene.
Yes, now everyone looked at Jiang Xia with puzzled expressions.
"Wait!" Factory Director Wang rushed forward, almost dropping the enamel mug in his hands.
"Jiang, this... this is too unbelievable!"
Factory Director Wang was filled with apprehension. Just yesterday, he had been boasting to his old colleagues at the neighboring equipment factory, "An expert from the traditional Chinese medicine factory has come, and our equipment is about to be upgraded from slingshots to cannons!"
As a result, today it has become "remodeling pen nibs". If this gets out, the Chinese medicine factory will be laughed at by others for using pen nibs to make machines.
"How about we... think of another option? Even buying a cheap copper nozzle would be fine!"
Factory Director Wang accompanied Cheng Gui to see the computer, where the unfamiliar experts gave their assessment of the young man. The experts kept praising his ability to "use what's available," but he never imagined that this "usefulness" could reach such a level!
Old Liu from the production department nodded in agreement, even putting down his notebook: "Engineer Jiang, this pen nib is as fine as an embroidery needle. If the extract is too thick, won't it clog the nozzle completely? Last time we tried the hand-cranked sprayer, and because the extract was too thick, the nozzle was so clogged that it took us a long time to clear it with a wire."
The fitter, Mr. Li, who came to help, didn't say anything. He reached out and took the pen from Jiang Xia's hand, then looked at it in the sunlight.
Hey, it really is the fountain pen I bought for my daughter last week. Tsk tsk, this thing is as thin as a piece of paper. I'm afraid it will deform if I squeeze it too hard since it's welded to a copper tube. And you expect it to spray?
This thing is perfect for sticking in your shirt pocket to show you're a cultured person...
Don't let the compressed air rush in and cause the pen nib to fly straight into the container; that would be a laughing stock.
Jiang Xia looked at the suspicious looks in the room, and even Old Wang, who was holding a cup of tea, secretly covered his mouth and laughed. He sighed helplessly.
Ah, I originally intended to turn my heart towards the bright moon... I wanted to keep things simple...
He turned and walked to the base of the freshly painted wall, wiping away the words "pen nib" that had been written there with his sleeve. With his elbow against the wall, he flicked his wrist and wrote a string of words that instantly silenced everyone:
"A gas-liquid coaxial micro-atomizing nozzle based on the Venturi principle!"
Cheng Gui leaned closer and read out each word carefully: "Ji, Yu, Wen, Qiu, Li... What is this?"
Factory Director Wang's eyes suddenly lit up, and he rubbed his hands together, repeating, "Venturi principle! Gas-liquid coaxial! Micro-atomizing nozzle!" Although he didn't understand the specific meaning, the words "principle," "coaxial," and "micro-atomizing" sounded a hundred times more sophisticated than "pen nib"!
Half of my anxiety instantly disappeared. I thought to myself: Jiang Gong is really knowledgeable. Changing the name makes all the difference. This sounds like technology developed by foreign experts!
Foreign products are just better!
Didn't you see that the Northeast Pharmaceutical Factory set up an alliance production line? They're all incredibly arrogant...
Old Liu from the production department quickly copied the string of words into his notebook, his pen tip almost piercing the paper. As he copied, he muttered to himself, "Venturi... is it an expert from the Alliance or from France? It sounds like a French name, so it must be high-tech!"
Wow, you know quite a lot...
Jiang Xia pursed his lips, but still cleared his throat and added, "This 'Venturi principle' was discovered by the Italian physicist Venturi in 1797. Simply put, it means that when a fluid flows through a narrow passage, its velocity increases and its pressure decreases. It's like pouring water from a teapot; the narrower the spout, the faster the water flows—it's the same principle."
"Oh! Now I understand! There's a teahouse at the fork in the road ahead run by people from Sichuan. The waiter there pours tea with such a long spout, the tea flows out in a whooshing sound. I thought he was holding it high... Oh, I see!"
Master Li slapped his thigh, somewhat amused: "You really have to be a cultured person! You can even talk about so many things just by pouring water..."
"Yes! That's right..."
Jiang Xia continued drawing, using chalk to draw an arrow at the narrow part of the pipe: "The tip of our 'nozzle' is the 'narrow part.' Compressed air flows from the copper pipe on the side, and the flow rate increases and the pressure decreases at the tip, which 'sucks' down the extract from the extract tube above. The two mix together and are then sprayed out from the tip."
When in operation, there's no need to consider congestion...
"As for whether this thing is durable or not... well, try to find Hero pens, after all, they've gone to the extravagance of using 'iridium' on them!"
Cheng Gui suddenly realized, and holding up his fountain pen, he said, "Then does my fountain pen use the same principle when it writes? The ink flows out from the nib because the flow rate is faster?"
"That's about it!"
Everyone nodded in satisfaction.
Even Lao Wang was secretly laughing behind the crowd with his arms crossed. However, what he was thinking was: "Hey, that's it, that's the style! First, I'll use a down-to-earth, unsophisticated method to scare you, then I'll use a high-level professional term to shock you."
This kid's getting better and better at this trick!
but……
Jiang Xia felt a complex mix of emotions as he watched the crowd's attitude change instantly.
He clearly sensed that an almost blind trust in "foreign terms" had been imprinted in the minds of many people.
Everyone is hardworking, diligent, and full of enthusiasm for construction, but when faced with concepts from outside, especially from the West, their recently straightened backs seem to have unconsciously bent down a bit.
"I'm flapping my little wings desperately, trying to bring about change, but it's not something that can be done overnight to truly build confidence in my own people and my own technology."
"But thinking about it carefully, can we really blame everyone entirely?" Jiang Xia's thoughts drifted further away.
Even decades later, before the country had become strong and proud, and before the 08 Olympics, weren't there still countless voices both domestically and internationally pessimistic about our motherland?
Only when aircraft carriers are launched and high-speed trains are running can people confidently say "China is on the move!"
Building national self-confidence has always been a long and arduous journey, requiring real and repeated victories to forge it.
But then, Jiang Xia's eyes suddenly lit up.
Exactly! We didn't dare show our true skills before because we were afraid of not having a powerful backer. Now that a "young lady" has suddenly appeared, even the French are scrambling to buy computers. Why should we keep our own hard-earned technology hidden?
Bring back more "world firsts" so everyone can see we're on the absolutely right path, then...
Hehe, I'm getting a little excited just thinking about it!
However, now is not the time to daydream.
Jiang Xia composed himself and coughed lightly:
"Alright, let's settle on this renovation plan. Does anyone have any questions?"
"and many more!"
"Jiang, may I speak?"
Just as Factory Director Wang was holding the blueprints and urging the newcomers to get to work, a young man who had come with Master Li raised his hand.
"Oh, please go ahead!"
"I...I wanted to ask, is the required temperature for this hot air 65 degrees Celsius?"
"Yes, that's right. This process requirement was proposed by Comrade Cheng Gui from the Chinese medicine factory, who said that only in this way can the required efficacy be achieved. Is there a problem?"
"Engineer Jiang! I've been dealing with hot blast stoves for almost ten years, and I can't meet your requirements!"
Jiang Xia looked at the reserved young man and smiled broadly: "What is your surname, Master?"
As if encouraged by Jiang Xia's smile, the young man composed himself: "Hehe, my surname is Liu, and my name is Guoqiang!"
"Jiang Gong, the hot blast stoves in the Chinese medicine factory are internal combustion type, unlike those in our steel plant. Our hot blast stoves use blast furnace gas directly, while these burn coal!"
"The wind from this coal stove is so hot and cold that it's impossible to keep an eye on the clock!"
"The solution is in the drawings! Look, it's 'a passive temperature-controlled coil based on fluid heat exchange'!"
"It starts with 'based on' again!" Factory Director Wang's eyes lit up even more: "Good, good, good! 'Based on' is great, it just sounds right! Let's go, let's get to work..."
As the crowd dispersed, discussing the new term "based on… principle," Liu Guoqiang remained. He rubbed his rough hands together, his face showing a stubborn determination to get to the bottom of things. He leaned closer to Jiang Xia and whispered:
“Jiang, those people get confused just hearing those foreign terms, but I can’t. Could you… could you explain to me in detail what that ‘passive temperature control coil’ written on the wall is all about?”
Please stop starting with 'based on'! It gives me a headache!
I just want to know, what exactly is this thing, and how does it manage to stop the fluctuating temperature of the coal stove's air?
Jiang Xia chuckled; the slight annoyance he'd felt earlier because of the "foreign term" vanished instantly. He patted Liu Guoqiang on the shoulder:
"Okay! I'll tell you the truth! This 'temperature control coil' is actually just an old water pipe wrapped around a few times!"
