C22 Train Power Technology Problem

Just as Zhang Hong, Zhao Cheng, and Zhang Yu implemented the education plan, as a technical school student, Su Jianguo was still working hard on the homework that Zhao Cheng arranged: researching the Xin Gan line train.

On the study desk in the dormitory, Su Jianguo placed dozens of hand-drawn blueprints. Each blueprint had complex data and calculation formulas.

Along with these calculations, there were also problems and questions marked with red and blue pencil.

Su Jianguo held a steamed bun in his mouth. As he flipped through the descriptions of the new train in the newspapers, he calculated the exact numbers of the new train.

For a whole year, every day after Su Jianguo's class was spent in repeated calculations and calculations.

Sometimes, when there was no more water in the warm pot, it was his considerate roommate who helped him get it.

On the bed of Su Jianguo, there was a model of the train that Zhao Cheng asked every student to research.

After another round of calculations, Su Jianguo still had not deciphered which section of the train was more suitable.

That was true. He had never seen a physical body, nor had he driven a train, nor had he personally repaired a train. It was impossible for him to calculate and calculate accurately.

Su Jianguo put down the pencil and took a bite of the mantou. Even if it was difficult, he had to find the core of the problem.

Fortunately, this year, the school introduced a microcomputer room. Although he could not agree to it, he could read the thesis in the microcomputer room.

Su Jianguo swallowed the dry bun and packed up the calculation paper. He carefully put the paper into the cloth bag and walked to the school's computer room.

Arriving at the microcomputer room, Su Jianguo entered his student number and password and started to search for relevant documents.

A thesis on the burning of the auxiliary compressor of the new train appeared in Su Jianguo's field of vision.

The excitement caused Su Jianguo's fingers to tremble. He quickly read to confirm it, picked up the red and blue end of the red and blue pencil, and quickly recorded the parameters written on it.

This was an empirical thesis. It explained a new train auxiliary compressor. Due to the high vibration impact, the air pipe between the air dryer and the regenerative cylinder was damaged. As a result, the result of the ignition of the generator was analyzed.

[Due to professional needs, reference paper is 2014 Youth Science magazine, Shanghai railway station Shanghai Train. The author is Yu Bin's CRH1 Type Train auxiliary compressor analysis and solutions for the cause of combustion damage. Document]

Looking at the air dryer and the regenerative cylinder, Su Jianguo had a flash of inspiration. Could this be the key to the power of the New Line Train Group?

After all, the places that were prone to malfunction were definitely the places that had the most wear and tear and had the greatest effect.

And these places were either places where the technology was not mature enough and caused frequent replacement, or because the technology was not enough to completely solve the problem, which resulted in frequent maintenance and malfunctions.

However, because of frequent malfunctions, it became the focus of the engineers and the topic of technological breakthroughs.

As if discovering a new continent, Su Jianguo earnestly read this document, searching for the knowledge points in it.

In 1991, Su Jianguo was only 19 years old. Currently, other than being poor, he could only work hard to learn.

Fortunately, this article described many things that he had never seen before, but they were truly important knowledge points.

Of course, this was also thanks to the Myriad Direction Data Base that was opened in 1991, as well as the China Knowledge Network that had started internal testing in 1991.

Although there were many words that Su Jianguo could not understand, and even though the technical terms were difficult to understand, Su Jianguo would rather copy them and find resources to verify the technical terms. He was not willing to give up the opportunity to grasp knowledge and understand the contents of the thesis.

After all, the cost of the microcomputer room per hour was too expensive for Su Jianguo, who was thrifty.

Following the description of the thesis, Su Jianguo saw a suggestion to strengthen the frame of the auxiliary wind supply unit.

The materials and technology used for this suggestion were not advanced research and development technologies. It was the consciousness of the engineers after many years of maintenance. It was the consciousness of protecting important components with small components.

After seeing the word two-way stop valve, Su Jianguo's eyes lit up again.

Two-way stop valve. . . This component might be the key to the problem this time.

As the thesis was read, the two-way stop valve leakage and the technical problem of compressing air to soak into the main power circuit appeared in front of Su Jianguo.

It seemed that it was really a problem of the two-way stop valve. However, this problem still depended on whether the transmission signal was in place.

When Su Jianguo moved the mouse to the next page, the words "electrical wiring," "air dryer pressure switch," and a few other words entered his eyes.

This is. . . This is the key to the compressor being burned down. Is this the burning caused by a signal transmission malfunction?

The solution is to eliminate the signal malfunction, increase the interval timer, and increase the reinforcing method of the wind supply unit to reduce the working time of the auxiliary wind unit and reduce the possibility of the burning caused by long-term work.

This solution appeared to be a small technical malfunction that could be eliminated, but it was practical to the knowledge of electromechanics and other things.

Su Jianguo copied the topic of the thesis and reluctantly closed the document.

After returning to his dorm, Su Jianguo looked at the knowledge he had copied and once again listed the key points of the problem.

Along with the new problems listed by Su Jianguo, one could clearly see the "electrical wiring" and "air dryer pressure switch. " These were the main technical problems at the moment.

And this technical problem had never been seen in the textbooks of technical schools.

Then, where could he find it?

Or, where can I crack basic theories and academic terms?

In order to solve this problem, Su Jianguo searched through the university books sent by Jianjun Cheng and carefully searched for the answers regarding electricity in the university books.

Finally, he found the answer in a textbook. It turned out that the air was not limited and had to be arranged according to the electrical principle diagram. It could not be near the heating temperature of a heating device within 100 degrees Celsius. The distance between the wires and the wires was above 20 mm.

For those with a temperature of 100 ~ 300 degrees Celsius, the distance between the wires and the wires had to be above 30 mm, and the heat had to be above 300 degrees Celsius. For those who did not have heat insulation or fireproof measures, the distance between the wires and the wires was above 80 mm.

Seeing so much data and knowledge, Su Jianguo felt that his technical school's knowledge was no longer sufficient to support the knowledge needed for the new train. Only after the university's textbooks had been updated would he be able to see some of the knowledge.

The power of books and literature deeply made Su Jianguo feel that he was powerless to study and that the resources available for research were scarce.

When he saw the relevant knowledge regarding "air dryer pressure switch," Su Jianguo realized that this knowledge actually had some sort of intersection with the knowledge of automatons.

Fortunately, Su Jianguo's teacher, Wang Ping, admired him and was even proficient in automation.

For this, Su Jianguo specially ran to Wang Ping's office and knocked on the door. Wang Ping nodded and said, "Come in. "

"Hello, Teacher Wang. "

"Wang Ping said, Ah, Little Su, take a seat. What business do you have with Teacher?" Wang Ping put down the document in his hand and looked at Su Jianguo. He was curious as to what question this Su Jianguo, who rarely came to the teacher's office, wanted to ask.

"Teacher, I want to learn some knowledge regarding automation. Do you think I can attend your class when I don't have any classes? Also, can I buy some books for my junior brothers and sisters as well? " Su Jianguo rubbed his hands and asked somewhat anxiously.

"Oh? You want to learn the knowledge of auto repair? Why? " Wang Ping was curious as to why this Su Jianguo, who was learning how to repair trains, would suddenly learn how to repair cars.

"It's like this, Teacher Wang. I saw in a thesis that mentioned the air dryer pressure switch. I checked the book and found out that it was related to auto repair, so I wanted to learn how to repair cars as well. " Su Jianguo handed his notebook to Wang Ping.

"Yo, this handwriting is quite detailed. It's not impossible for you to study as an automaton. It's just that learning is so stressful. Can you really learn it?" Wang Ping was very worried about Su Jianguo, who was very eager to learn. His body could not take it.

"As long as you are willing to give me the chance to learn, I will definitely be able to do it. " Hearing that Wang Ping's teacher was interested, Su Jianguo said seriously.

"However. . . You know that car repair and train maintenance are different after all. I am afraid that you will only learn how to make a string. " Wang Ping still wanted to tell Su Jianguo about his specialization.

"Teacher Wang, I want to learn more intersecting knowledge. Especially in the field of electricity and power. You also know that our professor, Teacher Zhao, has given us a research project with a deadline of two years, and he wants us to study it. This research project is about power and electricity. My current knowledge is not enough for me to understand some of the problems of power and electricity. That's why I want to learn the part of automation to fill in. " Su Jianguo sent a book to his university to Wang Ping from Jianjun Cheng.

"Teacher Wang, look. This is the railway knowledge I learned from my high school classmate's university books. Because of the assistance of the university's books, That's why I'm able to learn from technical schools faster than others. Teacher, I want to use the knowledge from the Automaton Department. . . It will also speed up my understanding on the power train. After all, cars are fuel-and-electric, and they have the knowledge of electricity and mechanics. It's very suitable for me to study the questions given by Professor Zhao. Do you think. . . You can give me a chance? "

Wang Ping looked at Su Jianguo's sincere expression and looked at the page in his hand. However, there was an envelope within every few pages. This was an envelope that others did not want. After Su Jianguo threw it away, he picked it up and made it into an envelope.

On each envelope, there were words that were carefully written and analyzed.

When Wang Ping saw that Su Jianguo was so serious in his studies, he could not help but soften his heart. "Alright, since you want to learn, come listen in when you have no classes. "

"Really? Teacher, thank you so much. I will definitely study hard. " Su Jianguo looked at Wang Ping in delight.

However, Su Jianguo did not expect that after several decades, all the engineers in China would have to learn electrical engineering, kinetic science, and other related subjects.

This was because China needed multi-disciplinary composite talents, as well as diligent and diligent students.

A hundred years of vicissitudes and a hundred years of revival. On the path of the rise of China, not only were there education workers and good leaders like Zhang Hong, Zhang Yu, and Zhao Cheng who devoted themselves to making talents shine, there were even good students who diligently studied and down-to-earth studies.

It was precisely this kind of earnest leadership and talent that allowed China to become the world's second largest economic and financial center during the 40th year of reform and opening up. It even had several decades of engineering dividends, and it was a hundred times more confident in reviving China, a country that was at the peak of the world. Reviving China was originally the world's greatest nation.
