Day by day.
Two days.
Three days passed.
Early morning three days later.
Today is the day to report to the Railway Research Institute.
Li Aiguo got up early, ate five steamed buns, felt full, and pushed his bicycle out of the house.
While passing by the door of Nan Yi's house, Liang Ladi heard the sound of the wheels and walked out holding Nan Xiaoying.
Nan Xiaoying is now more than three months old, and her little face has become chubby because of the milk powder.
This kid seemed to know Li Aiguo. He stretched out his hand and babbling even though he was far away.
“Patriotic brothers, are you going to work so early?”
"Yes, Xiaoying has grown so big."
Li Aiguo pinched Nan Xiaoying's little face and asked with a smile: "Liang Ladi, how is the transformation of the electric sewing machine going? Are there any difficulties? "
"No problem, all the materials are available, but the structure is a bit complicated. Give me another five days to make sure it can be transformed," Liang Ladi said, puffing up her chest.
"Don't be in a hurry, work slowly and carefully. I still have to go to work, so I'll leave first."
With a few words of advice, Li Aiguo left the courtyard, got on his bicycle and faced the golden morning sun. Heading towards the Railway Research Institute.
The Railway Research Institute attaches great importance to the improvement of the forward steam engine head.
A laboratory was specially allocated for the use of the renovation project team.
This laboratory was moved from Tangshan in its entirety last year, and the equipment inside has reached an internationally advanced status in these years.
Vehicle brake test device, brake regulator test device, bicycle brake tester, various valves and other locomotive test equipment are all available.
After the project team met in the laboratory, Dong Gong introduced Li Aiguo to the project team members.
"Everyone, this is Comrade Li Aiguo, the train driver at the Qianmen Locomotive Depot, who serves as the deputy leader of the improvement group."
As soon as he finished speaking, a young man in a gray tunic suit raised his hand.
"Mr. Dong, something is wrong. Li Aiguo is just a train driver and a worker. Why can he serve as the deputy team leader?"
Gong Dong looked deeply at the young man and said, He smiled and said: "This is the decision of Director Liu of the institute. If you have any opinions, you can mention it directly to Director Liu."
The young man did not speak anymore.
But the look he looked at Li Aiguo was still unkind.
Li Aiguo did not expect that as soon as he arrived here, someone would show his teeth.
“Who is this person?”
While the researchers were studying the locomotive drawings, Li Aiguo called Dong Gong aside.
Dong Gong looked up at the young man and said: "His name is Zheng Han, a graduate student at Xi'an Jiaotong University, a true son of genius. He entered the Datong factory last year and was designated as a fifth-level engineer. Now He is the technical backbone of Datong Factory
It’s not unusual to have a graduate degree. We also have four or five graduate students in our institute. The key is that Zheng Han’s supervisor is Professor Liu Zhengduo! "
Graduate students are not uncommon. He is just a technical secondary school student. Li Aiguo made a few slanderous remarks and said, "The name Liu Zhengduo is a bit familiar."
"Professor Liu Zhengduo is the chief engineer of Datong Locomotive Factory. Before liberation, he was already an authority on steam locomotives, and he also served as the general consultant of the First Machinery Department. "
"."
General consultant of the ministry. What a great background.
Li Aiguo can understand why Zheng Han can participate in the locomotive improvement work as a representative of the Datong Factory .
Zheng Han, who was studying the drawings at this time, was a little depressed.
His family came from three generations of poverty. His father, mother, brother and sister were all workers, so he would not look down on workers. Li Aiguo.
It’s just that Zheng Han thinks that there is a specialization in the art industry.
In such a technically demanding project, there are so many highly educated researchers, but a worker is appointed as the deputy team leader. A bit suspected of being in charge of remediation
As a researcher determined to study train technology, he has always hated this system.
And.
The big worker didn't seem to be in a hurry at this time. Instead, he discussed lunch with the logistics director of the Railway Research Institute.
The most important thing is that only Zheng Han in the entire improvement team knows.
The improvement of the forward steam engine is not only related to the opening of the bridge to traffic, but also related to an export order of up to 200 units.
If the improvement fails, millions of foreign exchange will be lost.
Logistics Director Zhou of the Railway Research Institute did not expect that he would be invited into the laboratory, and was wondering at this time.
"Old Zhou, you are the head of logistics and have a great influence on the locomotive improvement project team. Whether we can each have a bowl of pork stewed vermicelli at noon depends on you, brother."
Li Aiguo handed Director Zhou a cigarette and held his hands to light it for him.
It turned out that I wanted to open the back door. Director Zhou was smoking a cigarette and felt a little dumbfounded.
"It's not that we don't want our comrades to eat well, it's just that you know the current situation.
Pork stewed vermicelli is out of the question. The maximum is two bowls of white noodles per person, and I will arrange another bowl of braised noodles for you. "
"There must be meat in the stew. There are many of us, at least half a pound of meat."
"Deal!"
The institute is full of technology. He is a civilized person and has never bargained with him over food.
Director Zhou was really overwhelmed for a while, so he could only order the kitchen to cut a piece of meat for the visiting leaders.
"Thank you, brother. When you go to the Qianmen Locomotive Depot for a business trip, I'll treat you to a big dinner." Li Aiguo patted Director Zhou heavily on the shoulder.
After seeing off Director Zhou, he returned to his desk humming a tune, picked up a newspaper and read it leisurely.
Zheng Han shook his head depressedly: "It's an insult to gentlemen! How can such a person serve as deputy team leader."
The two comrades next to him knew Zheng Han's upright temperament and were afraid that He was making trouble, so he stopped him quickly.
"Xiao Zheng, driver Li is the deputy team leader, please pay attention to your attitude."
Zheng Han was feeling angry because he couldn't solve a structural problem. Now that he was reminded of his identity, he slammed the table .
"Comrade Li Aiguo, as the deputy team leader, you are not studying how to improve the locomotives, but are busy preparing lunch. Are you putting the cart before the horse?"
Literatured people are not ordinary, even if they get angry , still polite and polite.
The newspaper tilted sideways, revealing Li Aiguo's head. His eyes glanced at Zheng Han, and then were covered by the newspaper again.
A faint words came from behind the newspaper.
"I am the deputy team leader and the leader. Do I need to study those problems personally?
In that case, wouldn't it mean that I don't trust you technicians?"
The researchers nodded frequently.
The people selected here are all outstanding technicians from Datong Locomotive Factory and Research Institute, and they are confident that they can solve all problems.
Zheng Han felt that Li Aiguo was playing rogue, and was speechless for a moment.
"Since you don't like me preparing lunch, you can have a big pot stove with the comrades from the institute at noon."
Zheng Han raised his head: "What's so great! I This person never pays attention to material comfort!"
Li Aiguo did not continue chatting with Zheng Han and focused on the newspaper.
He found that being the deputy team leader was so comfortable.
Just check the modification plans submitted by the researchers, keep the suitable ones, and reject the unsuitable ones directly.
No wonder everyone likes to be a leader.
The time came to noon before we knew it.
In order to facilitate the work of the researchers, and to avoid trouble from the rude train driver, Director Zhou led a group of canteen workers to deliver the meals to the laboratory.
In the old Beijing language, white dough slices are white dough pieces.
The hot white dough is topped with the fragrant shredded pork stew. Take a sip while it's hot. The taste is incredible.
The salary of researchers is higher than that of ordinary workers, but the number of food rations and meat stamps is the same as that of ordinary people.
In the past six months, supplies in the capital have become increasingly scarce, and even large factories like Datong Factory can no longer get meat.
The researchers all ate deliciously, and some even took off their glasses in order not to delay things.
There was a fragrant smell in the room. Zheng Han was holding two steamed buns and eating stick noodle porridge.
Although there is also a dish of boiled cabbage, which is much better than the food in the Datong factory, it is hard to swallow at this time.
Although Zheng Han still doesn't think Big Boss can serve as the team leader, the braised noodles with shredded pork are really delicious.
He regretted a little bit for going up against Li Aiguo just now.
The researchers ate with gusto.
“I haven’t eaten meat for so long that I almost forgot what meat tastes like.”
"That is, Team Leader Li will come forward. If it were anyone else, we would definitely have to eat the big pot stove."
"Isn't Worker Zheng just eating the big pot stove?"
Listen Listening to the discussion, Zheng Han felt that the bun in his mouth was even more difficult to swallow.
"Eat, you will be full and energetic. In the afternoon you will change the sliding bearing of the water tanker into a six-axis rolling bearing and get the drawings out first."
A man suddenly appeared in front of you. When he had a bowl of braised noodles, the brown shredded meat exuded a greasy luster, and the air was filled with a fragrant smell. Zheng Han couldn't help but swallow his saliva.
This is not the key! The key is the bearings of the tender!
He raised his head and looked at Li Aiguo.
"Team Leader Li, what's wrong with the sliding bearings? Lao Maozi's water trucks all have sliding bearings!"
At this time, Li Aiguo had already turned around and walked towards the desk, leaving only Made a sentence.
“Eat first, and we’ll talk about this later when you’re full.”
Zheng Han looked at the rough steamed buns, then at the greasy shredded meat and whitewashed noodles, gritted his teeth and muttered.
"I'm not giving in, but I want to eat enough so that I can explain the benefits of the slider to that big boss! It's for work."
Zheng Han dropped the wowotou and couldn't wait to hug him He picked up the enamel bowl, picked up a shredded meat and put it into his mouth.
“It smells so good”
He started to devour it.
Li Aiguo smoked a cigarette and shook the newspaper.
Small, can’t I, the train driver, handle you, a little graduate student? What a joke!
With the bearing in mind, Zheng Han finished a large bowl of noodles in less than ten minutes.
Picked up a towel and wiped his mouth. He didn't even have time to clean the lunch box, so he came to the desk with the drawings. "Driver Li, as a train driver, you may not understand the advantages of sliding bearings. Let me explain them to you now."
Zheng Han was obviously well prepared and actually took out a Russian book and spread it in front of Li Aiguo.
“Sliding bearings have a stronger carrying capacity than rolling bearings, no noise pollution, smooth movement, safety and reliability. Ninety percent of Lao Maozi’s coal water truck bogies use sliding bearings. These are all basic knowledge."
Li Aiguo said only one sentence when facing Luo Liba's verbose Zheng Han.
“The forward steam locomotive is too weak.”
Zheng Han, who had looked confident just now, now opened his mouth and no sound could come out of his throat.
Many technologies of the forward steam train have reached the international first-class level.
In particular, the boiler adopts an all-electric welded structure without combustion chamber, which greatly extends the service life of the train and greatly shortens the maintenance period.
But it also brings disadvantages, that is, compared with locomotives of the same level, the horsepower is much lower.
Li Aiguo closed the book and handed it to Zheng Han: "We train drivers all know that if you want a horse to die quickly, use it to pull a cart.
If you want a horse to die quickly, If the child grows well, he must be driven by a big horse and a small cart.”
"But the horsepower of the steam engine has been calculated and fully meets the demand."
"Have you calculated the overload? Have you calculated the decline in horsepower? Have you calculated the wear and tear of the train?" Li Aiguo folded the newspaper and placed it on the table. .
This thing can cover a wall, but it is a good thing and cannot be thrown away as garbage.
Li Aiguo stood up and said: "Our purpose of modifying the locomotive now is to make the locomotive have as few failures as possible. To achieve this goal, we must increase the power.
Rolling bearings replace sliding bearings, which will It will increase motivation by ten percent."
Zheng Han's pupils shrank suddenly. He did not expect that Li Aiguo actually knew this knowledge.
Li Aiguo continued: "The bearing capacity of sliding bearings is indeed higher, but the installation requires high precision, and installation and maintenance are troublesome.
The workers are responsible for the installation, and the workers' skills are high It’s low. To avoid malfunctions, workers must have no chance of making mistakes!”
As soon as these words came out, Zheng Han could no longer say a word.
He did not expect that the theory of Lao Maozi he believed in would be vulnerable to this train driver.
There was silence in the laboratory, and the researchers had gathered around at some point.
They have been studying locomotives all year round, and many of them have received special training in Moscow. They think they already know a lot about advanced steam locomotives.
However, Li Aiguo overturned their perceptions with just one rolling bearing.
The key point is that Li Aiguo's considerations are completely correct in theory, technology and practice.
He is just a worker!
Zheng Han couldn't help but swallow his saliva and said timidly: "Driver Li, how do you know that you can increase the power by ten percent?"
"It's calculated." Li Aiguo waved to them. He waved his hand and said: "Okay, our workload is huge, and there are still many defects that need to be improved. Let's go back to work."
After that, he sat back on the chair, picked up the newspaper and shook it , and continued to read.
On the front page, there is a huge black traditional Chinese title, [Glorious Achievement and Great Victory—The Yumen Oil Mine, the first natural oil base, is basically completed. 】
The Yumen Oil Mine was built so quickly. It seems that the suggestions made during last year’s northwest trip have come to fruition.
Although it was impossible for his name to appear in the newspaper, Li Aiguo was still in a good mood.
With the oil production from Yumen Oil Mine, the domestic energy shortage will be greatly alleviated.
Li Aiguo picked up the enamel jar and took a sip of tea. Tsk tsk, it was still a large piece of tea leaves, which could not be poked by a needle.
Different from Li Aiguo's leisurely mood, the laboratory was in a state of hustle and bustle at this time.
Although Zheng Han had no way to refute Li Aiguo's statement theoretically, he still felt a little unbelievable.
He could not accept the fact that he was surpassed by a technical secondary school student.
A researcher suggested: "Since Deputy Team Leader Li said that using rolling bearings can increase the power of the locomotive by 10%, let's calculate it again. If the results are consistent, it means that Deputy Team Leader Li's suggestion is reliable. ."
Zheng Han also became energetic: "This is a good idea."
A dozen researchers worked with Zheng Han to calculate all the data.
For a while, there was a constant sound of crackling abacus beads in the laboratory.
Snap!
Half an hour later, the last abacus bead was fiddled with, and Zheng Han suddenly lay down on the chair.
A researcher asked: "Gong Zheng, how is it, what's the result?"
"Indeed. It's ten percent." Zheng Han still couldn't believe the result, but Abacus beads cannot be faked.
"Have you considered all situations?" The researchers took a breath.
They had just a dozen technicians, and their minimum education level was an undergraduate degree, and their minimum professional title was a seventh-level engineer. They did the math for half an hour.
Li Aiguo, a train driver, just casually said a number and hit the target?
Zheng Han did not answer them, but his behavior said everything.
I saw Zheng Han walking up to Li Aiguo with the drawings.
"Team Leader Li, what do you think of my plan for the design of rolling bearings?"
Are you giving in now?
Li Aiguo is not surprised at all by this result.
Because the plan he used was the final improvement plan of the forward locomotive.
The Forward locomotive is the most produced steam locomotive in China, and it is also the locomotive that has been improved the most.
From the production of the prototype car, it went through a total of eight major modifications and countless small modifications before the final plan was reached.
After so many transformations, the final plan is almost perfect.
Even after the rise of diesel locomotives, the forward locomotive still persisted until the 1990s, which shows its perfection.
Li Aiguo is not the kind of person who likes to care about things. He took Zheng Han's design and studied it carefully.
“Look, rolling bearings can be designed here.”
With just a few words of advice, Zheng Han felt suddenly enlightened.
It was a simple question, how could he not think of it?
"Driver Li, yes, yes, your method is much smarter, I understand."
Zheng Han suddenly found the feeling of being a student studying in school, while sitting Li Aiguo opposite him is Professor Shujin.
Zheng Han is the most talented researcher in the research team. Seeing his appearance, the researchers all looked at each other.
It seems that this comrade worker is really capable, so he was chosen as the deputy team leader.
Gong Dong was busy for most of the day and finally returned to the laboratory from the meeting in the institute. He was preparing to hold a research meeting to study how to improve the train.
While calculating the data, Zheng Han raised his hand and said: "Team Leader Dong, no need, Team Leader Li has already proposed an improvement plan. We are revising the drawings and don't have time for a meeting."
Team Leader Li? Dong Gong rubbed his ears to make sure he heard correctly.
Didn’t these guys still think Li Aiguo was a rough guy just now? How could they accept his transformation plan now?
He picked up a drawing with doubts and looked at it twice, and instantly understood the reason.
Dong Gong also sat down silently, picked up a pen and paper and started calculating.
The simplest thing in the world is to shoot an arrow first and then draw a target.
With the plan to replace sliding bearings with rolling bearings, the design drawings were drawn up in just one afternoon.
Gong Dong divided the final drawing into two parts and put them into two file bags. One part was submitted to the office, waiting for approval.
The other copy was sent directly to the preparatory meeting of the locomotive factory in Datong by train.
The mail delivery speed is too slow these days. There is no air transportation. Generally, it is trucks, cars, donkey carts, even bicycles and other means of transportation.
A letter may take more than ten days to be delivered to the recipient.
Emergency mail on the railway is delivered by train through a set of internal procedures.
This system can operate wherever trains can reach it.
After delivering the drawings and returning to the laboratory, when it was time to get off work, Dong Gong suddenly remembered something important.
"Aiguo, we got the rolling bearing today, what should we improve tomorrow?"
He knew very well that Li Aiguo would not give up so easily.
"Let's talk about tomorrow's matters tomorrow. I have to go back now!"
Li Aiguo laughed, put on his canvas bag, and rode his bicycle out of the research institute.
It is the hot season at this time. Although it is approaching dusk, the air is still hot.
Under the shade of the tree, two puppies were fighting, fighting fiercely.
This seems to indicate something.
Li Aiguo returned home and before he had time to rest, he was pushed into the bathroom by Chen Xueru.
“Hurry up and get clean!”
My dear, this is killing the goose that lays the egg.
Li Aiguo, Li Aiguo, is not someone to be trifled with. He directly used a move to stop Chen Xueru, directly knocking Chen Xueru to a standstill.
The night is getting darker.
Chen Xueru, who had been harmed five times, finally couldn't hold on any longer and lay on the bed gasping for air.
Her hair was sticky on her forehead, her complexion was flushed, and her bright red mouth kept muttering: "I'm going to die, I'm going to die."
Young man, I can't conquer you yet.
The next day.
Inside the laboratory of the institute.
Under the gaze of all the researchers, Li Aiguo picked up the chalk and wrote on the blackboard the words "Improve the smoke exhaust device and coal chute water distribution pipeline".
Same as yesterday, the researchers looked a little strange when they saw this transformation plan.
The difference from yesterday is that no one took the lead to oppose this time.
Not even Zheng Han.
Finally, Dong Gong raised his hand: "Patriot, can you explain it in detail."
"The smoke exhaust device of the forward train is defective, and smoke may occur during high-speed operation. Backflow may at least affect driving, but in more serious cases, it may endanger the life safety of the driver.”
Li Aiguo stood up and drew a sketch on the blackboard with chalk.
"Look, according to aerodynamics, it is running at high speed."
The laboratory suddenly became quiet. When Zheng Han saw that Li Aiguo had begun to lecture, he quickly picked up the pen and wrote down all the contents. Write it down in a notebook.
