A nation's industrial development begins with junior engineers.

Jiang Xia rested her chin on her hand, picked up the blueprints she had just found in the corner, and looked at them.

This was after he started the scanner to analyze the pump's condition, and he saw it from the scanner's prompt window.

"Huh? Based on these blueprints, I think we should help this factory out."

"Huh? What's wrong?"

"The hydraulic pump improvement diagram, although only the cavity has been changed, should not be much worse in actual use. That explains why the data measured in Jinan is different from that in Beijing."

"This factory has ideas, but we don't know who came up with this design."

They stopped the two's clumsy performance and asked for clarification on the whole story.

"Director Fan, first of all, can you confirm if this drawing was done by you? The handwriting on it looks a bit like the exit slip you signed."

Factory Director Fan took the blueprints, looked at them, and nodded affirmatively: "Yes, that's right. Where did you find them? You just sketched them out on the spot."

Wow, is this guy incredibly skilled? He can accurately locate the optimal fluid cavity with just a casual sketch? You must have calculated it countless times in private, right?

Did you perform the calculations directly based on the hydraulic oil?

Faced with a barrage of questions from Jiang Xia, Director Fan was clearly overwhelmed.

"No calculations or anything, I just figured it out myself after doing it for a long time. I just found this shape to be useful!"

Seeing that Jiang Xia was somewhat skeptical of his father's abilities, Xiao Fan quickly chimed in, "That's right, Engineer Jiang. My dad doesn't have any other skills, he's just fascinated by pumps. He started as an apprentice at a water pump factory back in the Republic of China era!"

"They even copied a 1-inch centrifugal pump at the Sino-French University's ironworks!"

"Even that engineer sent down from the Ministry of Machinery Industry is not as good as him!"

Jiang Xia frowned: "Since you're a veteran in the pump industry, why did you skip the initial trial processing? Otherwise, you wouldn't have produced so many substandard products, would you?"

Jiang Xia looked at Factory Director Fan's son. He realized that the factory director was an honest man, and his son wasn't as eloquent as the factory director. The noisy conversation earlier seemed to have been taught to the factory director by the son.

"Hey, let me tell you, this batch of steel was delivered from Shijingshan. When it was put into storage, my dad said he wanted to inspect it."

"Well, the engineers sent by the Ministry of Machinery Industry said that Shijingshan is a big factory, so how could the products they produce be substandard?"

“My dad didn’t dare to talk back to anyone. Later, he said that we needed to do a trial production. The engineer said that this batch of goods was urgent, and that the water plant’s water pipes had already been laid to the Zhongguan section, and water pumps were urgently needed.”

"And then there's your relationship..."

"Huh? Is this something I have to do with?" Jiang Xia asked in surprise.

"Yes! You got a drilling rig, and the communes below thought the hand pump was too slow, so they also came up with the idea of ​​a water pump."

"Look, the water pumps in the back don't have motors, and the pump shafts are extended by a section, just so they can be mounted on your little cannon."

Hey, so that's how it is. Jiang Xia initially thought they had recycled the motor that came with the water pump, but it turns out it was for the Little Steel Cannon.

That's quite an idea, and the processing skills are also quite good. At the same time, the workers in this factory must have worked incredibly hard to produce 6000 water pumps in such a short time.

If the factory manager could withstand the pressure from above and inspect the steel before it enters the warehouse, the outcome would be completely different.

"Look, that's the situation. It's not our factory's fault. Could you please help us report this to our superiors? Our factory can't be downsized!"

"cannot!"

"what!"

The two men surnamed Fan lowered their heads at the same time.

Factory Director Fan shed tears of regret, lamenting that his incompetence had led to the downfall of his entire army and that he was truly unworthy of being the factory director.

"However, I can let you appeal to the Ministry of Machinery yourselves and get these substandard products up to standard before you go!"

"Really?"

"Ok!"

"By the way, did you quench this batch of impellers? Was it water quenching or oil quenching?"

When it came to the specific process, Xiao Fan started to stammer and looked to Factory Director Fan for help.

"Oil quenching, using machine oil, No. 10 machine oil!"

"Okay, Brother Wang, call the factory and have some of our quenching oil brought over. Uh, the kind specifically for the gears of the small cannon."

With time running out, Jiang Xia decided to solve the problem first, otherwise the pressure pump would be too hot to handle.

The steel mill responded quickly. I don't know if it was because Yang Erlengzi wanted to have a bed to sleep in tonight, but in less than half an hour, Wang Tiezhu's Yellow River truck came running.

Without further ado, let's get started with the quenching oil.

You know what, this water pump factory is really well-equipped, even has induction furnaces, and the induction coil is just the size of the impeller, which really saves a lot of trouble.

Wait, no, that's an induction cooker! How come you have one of these?

"You guys have pretty complete equipment, huh?"

"Hehe, my dad made this. It's just that it can't be left on for too long, or the power company will come knocking on our door."

This pump factory manager is a real talent! His hands-on skills are way better than Xiao Dai Mao's.

"Hiss~~ You made this thyristor frequency converter yourself?" Jiang Xia pointed at a component on the electric furnace, somewhat surprised.

Factory Director Fan honestly shook his head: "No, this is not it. A friend brought it back from the Canton Fair. He said that this big-nosed one was thrown into the trash can when he was collecting exhibits, and he thought it was pretty, so he picked it up."

Wow, your friend's luck is truly incredible to find a thyristor-type frequency converter in a trash can.

"Then, based on the manufacturer's brochure, you made this induction furnace?"

As Director Fan nodded slightly, Jiang Xia remained silent for a moment.

Brother, if I told you this story, the readers would still think I made it up. Do you have a system too? And it must be much stronger than my insignificant system, right?

(This is a true story, but not about this product. The Sharingan skills of us Chinese are truly maxed out.)

The Canton Fair? No, there's a Canton Fair now? Jiang Xia asked curiously.

Factory Director Fan watched Jiang Xia's operations while slowly answering Jiang Xia's questions.

It turns out that the first Canton Fair was held in 57. It was even based on instructions personally given by Mr. Lianxi.

That year, the exhibition, held in the name of China Foreign Trade Corporation, invited 1223 traders from 19 countries and regions to participate.

That year, Guangzhou established a car company with over 60 imported European luxury cars, becoming one of the earliest companies in China to operate a taxi service. It was also known as one of Guangdong's "Three Treasures" (driver, doctor, and butcher).

That year, Motherland showcased more than 10,000 kinds of goods, and the total transaction amount reached more than 86 million US dollars.

It reached 20% of the total national revenue.

That year, telegraph operators' hands became like chicken claws from cramping, because telephone calls were too expensive, and people generally chose to use telegraphs to communicate with foreign clients over long distances.

That year, telegraph machines caught the attention of the bigwigs.

In short, Motherland has always been looking out at the world; there are just some things you don't know. Especially back in 58, she directly rejected Japan's request to participate in the conference—that was incredibly assertive.

This is one of the reasons why Lao Chao took over the air fryer deal.

As for the high-frequency electric furnaces that the Ministry of Metallurgical Industry "picked up" earlier, besides the influence of the United States, the Japanese also had a kind of appeasing mentality in them.

We've digressed; let's get back to the point.

The impeller surface, after being quenched three times, exhibits a restrained metallic beauty.

"Take it to the metallographic laboratory at the machine department and test it. Let's see how it goes!" Having learned something, Jiang Xia's attitude towards Factory Director Fan improved considerably.

Seeing that Director Fan had that embarrassed expression again, Jiang Xia's heart tightened: "Uncle, you don't even have metallographic testing equipment, do you?"

"No, no, I was just curious what kind of quenching fluid you used. It couldn't be ordinary machine oil, could it?"

Jiang Xia breathed a sigh of relief. If this continues, you might as well be the protagonist of this book.
