Do you still remember when your home uses natural gas?
In February 2000, in order to avoid the trouble of burning coal and changing to gas tanks , and to avoid the impact of burning coal on the environment, the first meeting of the State Council approved the launch of the "West-East Gas Pipeline" project.
The project is so vast that it is no less than Three Gorges of the Yangtze River . However, this historic task that almost spans the entire land of China has almost failed due to the "difficulty" of the United States.
A technology used in the "West-East Gas Pipeline" process was monopolized by American companies at the time.
After learning about our country's grand plan, the United States actually asked our country to pay a sky-high patent fee of "200 million yuan per day" .
There is a saying that if you don’t steam buns, you will be more eager to make a living. In order to prevent the US from succeeding in its tricks, our country decided to independently develop it.
The sky-high patent fee in the United States
After the reform and opening up , all industries in my country have achieved explosive development, and the unreasonable structure of the energy industry has been unresolved.
Western regions such as Qaidam, Shaanxi, Gansu, and Ningxia, Tarim have rich natural gas resources, accounting for about 87% of the country's total natural gas resources.
Natural gas can generate electricity, and the chemical raw materials made from it have low cost, low energy consumption and are more environmentally friendly.
In addition, after repeated research by professionals, natural gas can also be used in people's livelihood industries such as gas stoves, water heaters, cooling or heating.
However, in central and eastern my country, coal has been used in large quantities. The carbon dioxide produced by coal combustion has extremely bad impact on the environment, and how to effectively utilize natural resources has become the top priority.
Under this situation, the "West-East Gas Pipeline" project came into being. After the project of
was approved, the relevant person in charge made a detailed plan: the total length of the natural gas pipeline transported by
is 4,200 kilometers, involving 16 regions including Xinjiang, Ningxia, Shaanxi, Hubei, Jiangxi, Hunan, Henan, Shanghai, Jiangsu, etc., almost traveling through the entire China.
If this project is implemented smoothly, 400 million people will benefit, and it is expected to reduce the combustion of 12 million tons of coal, which not only protects the environment, but also facilitates people's daily lives.
does it as soon as possible. After layers of approval, the project quickly entered the implementation.
However, just when everyone is full of confidence and is ready to do a big fight, the first "stumbling block" of appeared.
Because it involves a wide area, the span of the pipeline responsible for transporting natural gas must be very large. In addition, the terrain in various parts of my country is complex, including mountains, basins, Gobi, etc. If the power of natural gas itself is used alone, such a huge success cannot be achieved.
As long as your mind does not fall, there are always more solutions than difficulties. In order to solve this problem, the scientific researchers in charge of the project decided to set up a large artificial pressurization station every 200 kilometers.
In manual pressurization, the most core technology is the large compressor unit technology. At that time, only General Electric Co., Ltd. in the United States developed this technology. If other companies want to use this technology, they would have to pay a certain patent fee to the United States. It is understandable that
pays the patent fee. After all, American companies also used a lot of manpower and financial resources when they first developed this technology. The most important point of
is that since this technology was successfully developed, it has been monopolized by American companies for 50 years. In the past few decades, no country has made breakthroughs in this technology.
In order to make the "West-East Gas Pipeline" project go smoothly, relevant persons in charge of our country went to negotiate with American companies.
Unexpectedly, American companies were cautious. They believed that once the "West-East Gas Pipeline" project is successfully completed, it will bring huge benefits to China.
In view of this, the United States has proposed a sky-high fee of "200 million yuan per day".
200 million yuan per day. What is the concept of China that was developing at that time? If we compromise on this and use American technology to successfully complete the "West-East Gas Pipeline" project, where will the 200 million yuan per day cost be paid?
If the people are asked to bear it, what is the significance of this project?
The greed of the United States has made countless Chinese people indignant. After weighing the pros and cons, my country has made a bold decision: independently develops, breaks the monopoly, and is no longer subject to others.
Cui Lianshun successfully developed technology
After research, the task of development was handed over to Shenyang Blower Group . After repeated screening within Group, the arduous task was handed over to design engineer Cui Lianshun.
Cui Lianshun is a very low-key person. After receiving the task, he showed unprecedented excitement and tension.
On the one hand, she felt that being selected as the commander-in-chief of this mission means that everyone is very aware of her ability. On the other hand, she was not sure enough to develop the compressor unit technology that the United States had monopolized for decades.
Although she thought so in her heart, she was very positive in her actual actions.
"Before conducting research and experiments, we must understand three points."
"The first point is that an important part of compressor unit technology is the ternary compression impeller technology. To manufacture compressor technology, we must first study the ternary compression impeller technology."
"The second point is that the important key to conquer impeller is to manufacture low-temperature-resistant processing raw materials: steel billets."
"The third point is that in order to ensure the originality of research and development, all raw materials must be guaranteed to be made in China."
After confirming these three points, Cui Lianshun and all researchers began to practice.
People who do big things must pay attention to details. In order to ensure the fineness of the billet, Cui Lianshun asked everyone to strive for excellence, starting with the smallest blade, debugging little by little, and not making any mistakes.
You should know that the entire "West-East Gas Pipeline" project runs through almost all over China. Once problems arise during use, the losses caused will be unpredictable.
During those days, Cui Lianshun almost lived in the laboratory. After repeated calculations and designs with her team members, just to accurately data. Moreover, the steel billet processed at low temperature is a metal material with extremely high cost, and the R&D cost is limited. Cui Lianshun must do it, which not only saves costs, but also produces R&D results.
Because there is no experience in China to learn from, Cui Lianshun can only rely on the engineer experience accumulated before, research and try a little bit.
I don’t know how many failures have been experienced, but Cui Lianshun and the others have finally completed the preliminary technical research and development. Successful research and development does not mean that the technology is feasible. Next, it is necessary to put the finished steel billets into the workshop for testing.
test is divided into 3 stages:
The first stage is to observe whether the compressor unit can operate normally within 30 minutes.
in the second stage, observe whether the compressor can run overspeed for 15 minutes.
The third stage, after the work of the first two stages is carried out, let it work for another 4 hours to observe its operation.
can only be ensured to be safely put into use after passing the above tests. During the test, Cui Lianshun's expression was particularly serious. She stared at the data without turning around, and everyone was silent. Everyone was nervous.
Can China develop its own compressor unit technology? Let's see this last try.
1 hours passed, 2 hours passed, and time whizzed by.
After several hours, there was no abnormality in the compressor unit.
China finally developed its own technical means in the field of large compressor impellers, completely shattering the malicious difficulties of the United States and repelling its conspiracy to hinder China's development.
What makes people even more incredible is that this technology has been monopolized by the United States for 50 years. It took only 9 months for my country's female engineer Cui Lianshun and his team to overcome this technology, becoming the second country except the United States to have this technology.
"West-East Gas Pipeline" project ended perfectly
The most difficult part has been solved, and the "West-East Gas Pipeline" project has been carried out smoothly.
Looking at all the parts with "Made in China" , the American company that attempts to slander China's theft has no choice but to do anything.
In 2009, following the "West-East Gas Pipeline" project, the " Sichuan Gas East-East Gas Pipeline" project was also put on the agenda.
This project is expected to transport about 12 billion cubic meters of natural gas in Sichuan, Jiangxi, Anhui, Shanghai and other places, increasing revenue of about 20 billion yuan for Sinopec .
With natural gas, people's lives are more convenient, but the price of natural gas has not increased due to the long transmission distance.
It can be said that Cui Lianshun's technical research and development not only saved the country 200 million yuan in patent fees per day, but also solved the problem of unbalanced resource distribution in my country, but also saved the daily consumption of thousands of households.
Su Yongqiang, chairman of Shengu Group , said that he never thought that Cui Lianshun could overcome this problem in less than a year.
"Before us, many countries have started to study this technology. Over the years, they have made very slow progress."
Cui Lianshun was very calm about the ability of technology to be successfully developed. She said that she would not be discouraged if she failed, and that she would succeed was also a result of hard work.
, Cui Lianshun has always been very low-key. Until now, the news about her on the Internet is limited to the development of compressor technology.
But her contribution and influence to the country are epic.
After the first-line project of "West-East Gas Pipeline" was started, the second-line project also began to be invested in construction, with a total cumulative investment of up to 290 billion yuan.
Thanks to the maturity of large compressor technology, the first- and second-tier projects were completed as scheduled in 2007.
On September 23, 2021, the third-line project of "West-East Gas Pipeline" - Zhongwei -Jian section began to be built in Ningxia.
On September 28, 2022, the fourth line of the "West-East Gas Pipeline" project was officially started.
Since then, the "West-East Gas Pipeline" project has made the "five best" of natural gas transmission in my country: has the longest distance, the most investment, the largest gas transmission volume, the largest pipe diameter, and the most complex construction conditions.
Natural gas has entered thousands of households, making it convenient for countless Chinese people. Now, many years have passed since the construction of the "West-East Gas Pipeline" front-line project. In the past ten years, my country has completed technological innovations again and again and achieved one brilliant achievement after another.
Conclusion:
Shu Ting in " to Oak " describing love, telling countless young men and women: be a tree and stand with your beloved.
You have your copper branches and iron trunks, like a knife, like a sword, and like a halberd;
I also have my red flowers, like a heavy sigh, and like a heroic torch.
This is how people get along with each other, and so is the interaction between countries.
Only when one is strong can one have no right.
And every era has its own difficulties that every era has to face. I hope that we, who are in this era, can still overcome difficulties together and forge ahead!
