Nearly an hour later, before Li Tieguo arrived at the scene, the locomotive had been pulled by the rescue train to the nearest vehicle parking fork, so after Li Tieguo arrived, he first learned about the simple situation from the driver and other rescuers, and then he turned over directly, got into the driver's seat of the locomotive, and slowly after the car, he frowned and listened quietly,

But where can this kind of problem be heard, this is not like the external parts of the bearing, once there is a problem, the old driver knows what is going on when he hears it, so half a minute later, Li Tieguo frowned, without a word, and when he got out of the car, he only said a word to the person next to him, the traction problem can only drill the diesel engine,

Then before others asked him, he took off his clothes and rushed directly into the diesel locomotive suitcase, and in the spring and summer, the weather was originally very warm, it was a very comfortable climate, but it was not the case in the diesel engine compartment, the huge diesel engine that ran all the way, the heat emitted was amazing and even terrifying, Li Tieguo just rushed in, and instantly a heat wave hit, and he was sweating after more than ten seconds, and after a while, the beads of sweat flowed down, and Li Tieguo was almost fifty people. The body's heat resistance is much worse than before, so in less than ten minutes, Li Tieguo was almost confused by the heat, and his breathing was uncomfortable.

But he was not only in the diesel engine, but also many technicians went in, including a deputy section chief, since Li Tieguo entered the diesel engine compartment on his own initiative, he has been following Li Tieguo, first wanted to invite Li Tieguo out, and he could do technical guidance outside, but later found that Li Tieguo didn't listen to him at all, so he had no choice but to help Li Tieguo with tools and flashlights, and he was a little worried from beginning to end.

After all, this old comrade's body is different from that of young people.

"I can't see anything wrong with the diesel engine system, the traction failure may be in the connection position, go to the gearbox and the electrical interface and other positions to look for it, I can't stand the heat here, go out first!"

After Li Tieguo probably checked the diesel engine, to be honest, it took less than ten minutes to check the diesel engine, which is indeed a bit rough, but Li Tieguo will really reach the limit, forty or even nearly fifty degrees of indoor high temperature, in the spring and summer, it is really easy for people to not be able to transmit gas, and he has these years of experience, at least he can ensure that there are no common faults in the diesel engine, if there is really any fault that is difficult to find, or the problem in the diesel engine, then it can only be pulled back to disassemble and overhaul.

But soon after Li Tieguo went out, the people inside told him to come in and take a look, so Li Tieguo took a few breaths, and then he got in, and then he stood in front of the gearbox and smiled, the problem was really in the connection position, the gearbox was empty, and the gear run-in could not move, so he waved and signaled everyone to come out,

"I'll start by saying a few simple gearbox oil throwing is not common, you will go in and check what I said later!"

"First of all, the bolt problem, you will go in to see all the bolts on the gearbox, whether it is marked with No. 45 steel, No. 45 steel fastening force is insufficient, easy to loosen, the oil in the tank may be a large amount of light from the gap, if it is this problem, then replace the new type of slowing bolt, if there is an outer six type bolt is the best!"

"Secondly, because our type of locomotive has only one sealing groove, the sealing effect is poor, the design of the stiffener does not meet the requirements, and it is easy to crack. When I return to the section for overhaul, I recommend replacing it with a gearbox with double sealing slots! ”

"Then, if it is the gearbox closure and the top of the bearing pad to throw oil, it is the felt leakage failure, disassemble the gearbox to replace the felt, and seal the joint with "1587" sealant! ”

"As for the other common problems and the height of the fuel tank and the width of the felt, etc., I won't say more, if there is no problem, let's start overhauling"

Li Tieguo did a simple division of labor and precautions on the spot, then sat on the ground, this will he is still a little out of breath, it is inevitable to be old, but fortunately, the problem is not big, and after more than half an hour, the gear groove of the locomotive was finally repaired, according to the person who went into the repair or there was a problem with the sealing groove, the locomotive has been used for a long time, and the sealing groove has cracked, resulting in oil leakage.

And there are countless similar accidents like this in Li Tieguo's work in the past few years, he almost runs on the railway line every day, or in the large-scale maintenance base, in short, his life is busier than before, because at that time, there were fewer people who had studied in college, and there were fewer experienced technical backbones.

So people like Li Tieguo need it everywhere, after all, foreign manufacturers almost do not pass on maintenance technology, just like building locomotives, are highly secret, but despite this, China still built its own Dongfeng diesel locomotive series, completely domestic, the pride of the Chinese, and the maintenance technology is the same, must have their own technology, or always rely on foreign maintenance or that problem, several years of maintenance money is more expensive than locomotives, like robbery, Therefore, many times Li Tieguo and these people also hold meetings to discuss the in-depth maintenance of diesel locomotives.

These include optimizing maintenance technology, such as the improvement of the cooling air pump, that is, through the use of high-quality mechanical seal rings and the use of multiple seal structures, so as to improve the life of the mechanical seal structure, improve the reliability of the water pump, as well as the control and improvement of black smoke from diesel engines, improve the maintenance quality of the supercharger by replacing the rotor, realize the real-time control of the mechanical handle position through programming, improve the acceleration, and improve the slowdown of the locomotive traction ventilator, etc.

However, with the continuous deepening of the study of diesel locomotives, in just a few years, the locomotives began to be updated again, and electric locomotives began to be popularized in China.

In this regard, Li Tieguo began to study electric locomotives again, and the branch said that he would send a senior technical engineer like Li Tieguo to study in a university, but Li Tieguo refused at that time, saying that these opportunities were still left to young people, and he couldn't learn anymore, and even if he learned it, how many years could he still practice? So he said that he still taught himself this aspect, and he could do as much as he could, and if he met someone who really didn't understand, he would ask and read the book, and he would understand.

Li Tieguo and many school teachers and experts know each other, so if there is anything that will not be in the field of knowledge, it is very simple to ask if you want to borrow a book to see, and because of this incident, the leader also deliberately went to Li Tieguo's home, which probably means that Li Tieguo should not care about his age, and the unit will rehire him at a high price after retirement, and Xu Fangling and Li Tieguo are at home, Xu Fangling sat aside and listened to these words,

At that time, before Li Tieguo could answer, she dragged Li Tieguo back, and then smiled and said to the leader thank you for the kindness of the unit, but the pension of the two of them was enough to spend, and the child was also working on the railway, so there was no need to worry about it, and they didn't want too much money.

And Li Tieguo basically didn't say anything from beginning to end, as if he was protected by Xu Fangling, and Xu Fangling did this not without reason, she is a doctor, she has witnessed Li Tieguo's injuries, crimes, and burdens over the years, so she understands Li Tieguo's physical condition, which is indeed a little not good, especially the injury on his leg, sooner or later he will have to go to crutches,

And Li Tieguo stood beside Xu Fangling from beginning to end, and he didn't know what he should say, and finally after the leader left, Li Tieguo whispered to Xu Fangling that he was fine, but then after Xu Fangling glanced at him, Li Tieguo was also a little helpless, but in the next few days, Li Tieguo was not idle, he couldn't stay as long as he could move, he asked for some books and a lot of information, according to his past experience with internal combustion engines, he also studied electric locomotives, The so-called electric locomotive is the locomotive that uses electric energy to drive the operation of the electric motor, and the average thermal efficiency of the tram is higher than that of the diesel locomotive, which can improve the transportation capacity of the railway, make more reasonable use of resources, protect the ecological environment, and is the most ideal traction power for the railway industry, and the electric locomotive is divided into DC impulse electric locomotive according to the transmission mode, AC transmission electric locomotive, DC transmission electric locomotive is divided into DC power supply and AC power supply. The typical model is the Shaoshan series electric locomotive,

After half a year of study and on-site understanding, Li Tieguo once again relied on the strength of hard work, and in the age of retirement, he almost overhauled the electric locomotive, and in the six months he studied, he also dealt with several electric locomotive accidents, in fact, he didn't understand many times, so he could only grope around.

There was a D-shaped train in Tongcheng not far from the station, for leakage, at that time Li Tieguo in the nearby section of the school to investigate, so when he heard this thing immediately followed the rescue train to go, and then at the scene and some technical teams stood for analysis, at that time Li Tieguo according to the knowledge learned, said that it is recommended to check the battery and box first, according to Li Tieguo's traditional crack and leakage loose thinking, the electric locomotive leakage is likely to be loose skirt, the box suspension is not correct or the installation bolts are loose, the box has cracks, Moreover, the liquid level of the battery is at the highest liquid level, etc., but no matter what, Li Tieguo is going to go in and open the skirt.

And those people on the scene can't compare with Li Tieguo in terms of qualifications and experience, and they don't have Li Tieguo in terms of technical level, and Li Tieguo is also a well-known technical job in the bureau over the years, and he is a respected person.

And Li Tieguo is also used to taking people to deal with locomotive failures on the spot, and he is also very confident in his technical level, and locomotive fault handling is also in a fast word, so Li Tieguo didn't think too much, and thought that everyone and him thought of a piece, so a group of people ran into the car, opened the motor skirt and checked it, but scattered for half an hour passed, and did not find where it was loose and cracked, so Li Tieguo stood in the locomotive and frowned, a little confused,

And at this time, a young man of the same age as Li Tieguo's son poked his head in from the outside and looked at Li Tieguo, just now they were all seen by this young technician in the maintenance process, so he didn't understand a little, and wanted to ask the seniors for advice,

"Li, Master Li!"

The young man turned over and entered the carriage and stood beside Li Tieguo, looking very cautious and cautious, it seemed that he really had a question to ask.

"What's the matter?"

Li Tieguo was sweating profusely and was a little irritable, but the tone in which he spoke to this young man was quite good.

"Master Li, I... It's an intern here, I just came out of campus and I don't have much work experience, and I don't have many opportunities to meet a senior engineer like you, so I want to ask what type of leakage problem this time is, it's different from the regular one, can you briefly say a few words for me to write down?"

This young man looks like the kind of diligent and studious person, and when he asks questions, he looks humble and doesn't say anything, and he is very serious, and he must be a good seedling of some university.

And after listening to the words of this descendant, Li Tieguo stood in place and looked at it, then looked at the person next to him, swallowed his saliva a little embarrassed, and he didn't know what to say about it.

"How can you tell that this isn't a regular leakage problem?"

After thinking for a few seconds, Li Tieguo asked with some doubts, and the junior student was stunned for a moment when he heard this, then stood in place and looked a little overwhelmed, and after looking at the team leader who brought him, he scratched his head,

"Conventional leakage isn't all... Is it tested with a line light? One end of the light line is connected to the ground wire, and one end is connected to the positive and negative lines of the locomotive, and the lights are on when the positive line is connected, and the negative line is on when the negative line is connected, and the positive line is the problem.

The young descendant saw that Li Tieguo had been staring at him all the time, he was very nervous, and then he spoke as reasonably as possible, he was afraid that he would make Li Tieguo angry if he didn't understand what he said, and after Li Tieguo listened to his words, his expression was slightly puzzled and embarrassed, he stood in place and looked at others,

"You all know this way?"

Li Tieguo's tone was a little skeptical when he said this, and he also wanted to see if others recognized this method, but it was more of a kind of weakness, because he... I don't understand,

And after Li Tieguo finished asking, some of the technicians standing around him nodded and some were silent, so Li Tieguo understood, and then he turned around and patted the shoulder of the junior who was an intern.

"Some problems require experience, and some problems need to be processed, I just came with my habits, and what you said is also right!"

As soon as Li Tieguo's voice fell, he turned around and walked out, the sun at this moment was particularly dazzling but also shining, he was in a heavy mood but also very relieved, and then in the next time, Li Tieguo did not continue to stay, and went back to Duan Li to take a ride home,

In the evening, Li Tieguo called his son, a family of three around the dinner table, Li Tieguo asked his son about the electrified railway, and also asked about today's accident incidentally,

And his son's solution is the same as what the posterity said, so Li Tieguo smiled on the spot, his eyes were a little red, he was a proud person, but at this time he had to admit defeat, since ancient times, the waves pushed the waves, a generation has a generation's mission and responsibility, Li Tieguo had to say that he was outdated at this time, he couldn't keep up, but he was also very happy, his backwardness also means China's take-off and rapid development, he is willing to fall behind like this,

After the meal, Xu Fangling had already noticed Li Tieguo's mood and eye circles during the meal, so when she was about to go to bed, she asked Li Tieguo, Li Tieguo did not hide it at that time, and told her directly,

"I drove a steam engine for half my life and repaired an internal combustion engine for half a life, but I didn't expect to be overtaken by a bunch of cubs in the end, the world is impermanent!"

Li Tieguo sat on the sofa with his hands drooping, looking at Xu Fangling helplessly, as if sighing,

"You're okay, a person of such an age is what to compare with a young man!"

Xu Fangling cleaned up the wardrobe and coffee table, her tone was a little complaining, and her expression was a little angry, and after Li Tieguo listened to her words, he laughed, picked up his big teacup and said to go to Wu Laosan, and after Wu Laosan was rehabilitated, he was promoted to a deputy director-level leader, but he retired after a few years.

As for the relationship between Li Tieguo and Wu Laosan and Zheng Duoyu, these old buddies have always been very good, no matter what they have experienced over the years, but the years of hard work together will never be erased, their generation has a common mission, that is, to fight for the cause of communism for life, and this is also the mission of every generation of China in the future.
