I brought a Jurassic

Chapter 319: You also understand this? A little bit, a little bit

"Where are your parents? Why are you here alone? This is a professional book. I don't think you will like it or understand it. I just bought a set of newly released comic books as a gift for my old friend's grandson. It's more suitable for you to read. I'll lend it to you today, but don't make it dirty, otherwise it will be bad if you give it away again!"

As the old man was talking, he was trying to find the comic books in the luggage bag he was carrying. He really treated him as a child.

"Uncle, I'm already fifteen years old, why am I reading comic books? Aren't these just basic mechanical principles and advanced mathematics? I just want to study mechanics these days!"

"Hey, kid, you're quite arrogant. What do you mean, it's just basic mechanical principles and advanced mathematics. Can you understand it?"

When the old man heard this, he immediately laughed and felt that Wang Luo was an interesting kid.

"You're looking down on me. After all, I'm a technical secondary school student now. I'm very good at math. This time I'm on a business trip. Look, who else would go on a business trip with me, a kid of your age?"

"On a business trip? Why are you on a business trip at your age?"

The old man suddenly became confused.

"There is no other way. If I know a lot and the country needs me, I will have no choice but to abandon my own comfortable home and go on a business trip far away!"

"Good boy, I didn't expect you to be so capable. What's your name? What major did you study in secondary school?"

"Wang Luo, a student at Beijing Accounting Vocational School, is on a business trip for agricultural matters!"

Wang Luo told the truth.

"Wang Luo from Beijing, studying accounting. Hiss, why does your name sound so familiar?"

The old man couldn't remember where he had seen this name and immediately fell into deep thought.

"Hahaha, this kid does have some fame. He once killed a tiger with his bare hands and invented some gadgets!"

"Oh, now that you mention it, I finally remember who you are. You are the inventor of the credit-collection accounting method, the guy called Little King by Zulong, and the guy who invented the corn thresher and sweet potato slicer!"

The old man slapped his thigh and suddenly realized.

"Hahaha, I didn't expect that I would be so famous. Even a total stranger knows me!"

"How can I not know each other? I'm Zhang Xueming from the Department of Mechanical Engineering at Fudan University in Shanghai. I've been dealing with machinery all my life, and I've been thinking about researching some high-end machinery all day long, but I never thought of inventing something practical for us ordinary people. The machines you invented made the teachers and students of the Department of Mechanical Engineering in our school depressed for a while. You were actually surpassed by a student studying accounting." In this way, the two of them got to know each other and started chatting.

Don’t ask Wang Luo why he always meets professors or something like that every time he takes a train. The reason is that these are soft sleeper trains, which ordinary people can’t get. Wang Luo is not qualified, but there is no other way, he just meets some acquaintances.

"Professor Zhang, are you going to Beijing to visit relatives or friends or on official business?"

"Why call me Professor Zhang? You can just call me Uncle Zhang. This time, I'm on official business. I'll even stay in Beijing for a while, and even go to the Northeast. Our country's construction lacks oil. Look at many places that rely on gas to put a big bag on the car. It's so embarrassing. Without this oil blood, how can the country develop?

Isn't it that a huge oil field has been discovered in the northeast, and we, the mechanical engineers, need to research oil-making machines. We can't just rely on imports, because that would not only cost us foreign exchange, but also put us under the control of others. It's never as reliable as having it in our own hands!"

It was not a confidential matter, so Professor Zhang told me so.

As for the oil pumping units, the Daqing Oilfield is now conducting experimental exploitation, and our country is currently unable to independently produce oil pumping units. In the past, we imported the conventional CKH walking beam oil pumping units from Russia. But now, the "honeymoon period" is over, and it is no longer easy to import from Russia. We can only produce them ourselves. Now we have gathered together to do reverse research and development.

When Wang Luo heard this, hey, if you hadn't told me, I really wouldn't know the historical development of oil extraction machines in our country, but I really understand oil extraction machines myself.

Although I majored in electronic research and development, there is no machine in later generations that did not use CNC problems. When I graduated from graduate school, I followed my supervisor to participate in the design of oil pumps, which were tower-type CNC oil pumps. Of course, I studied the CNC electronic program part, and the mechanical part was not his field.

But that didn't stop him from staying in this research group for nearly half a year. He was very familiar with the mechanical principles there. He also followed the engineers and teachers around and listened to them explain the structure and history of the oil pumps. He became familiar with them.

This tower-type CNC oil pumping unit is a perfect combination of integrated innovation of modern mechanical manufacturing technology, control technology, power electronics technology and mechatronics technology. It adopts a control system to drive the motor to operate, and through the combined reduction transmission, the power source and terminal load of the oil pumping unit are reversed, dragging the sucker rod up and down repeatedly. The sucker rod and the counterweight form a balance like a scale, and the process of constantly exchanging storage and release of potential energy achieves balance during operation, so that the mechanical efficiency reaches more than 90%, and the reactive loss is close to zero, which has the effect of using a small force to move a large object. Compared with conventional oil pumping units, the energy saving effect reaches 30~70%, which solves the problems of low mechanical efficiency, difficulty in achieving long stroke and high energy consumption of conventional oil pumping units.

It is many times more advanced than the current old conventional You Liang oil pump, so he has a very detailed understanding of all the previous oil pumps. He did not expect that this would come in handy. It has to be said that time travelers will change some things inadvertently.

"Okay, I'll call you Uncle Zhang from now on. But I've seen the oil pump you mentioned in some magazines. I'm interested in machinery and have some experience with it. Anyway, we don't have much to do on the train except eating and drinking and reading. How about you give me some white paper and a pen so we can discuss it?"

This is a contribution to the country, there is no need to hide it, so I spoke up immediately.

"You understand this too?"

Wang Luo's words broke the silence in the box. Professor Zhang was confused. What's wrong? Can you, a little guy, do mapping? This is a professional issue, not the simple thresher and slicer you invented. If you know this, how can I, a professor specializing in machinery, deal with it?

"I know a little bit, I know a little bit, let's communicate with each other, and by the way, you can correct me. It just so happens that I also want to learn some mechanical knowledge recently. I already know accounting. I have nothing to do all day now. I have started raising pigs at school. This business trip is to go back to my hometown to help the folks there build a farm!"
