40 Thousand Five Air Compressor Compressor Designers

One summer day in August 1998. Wang Yingjie, a female engineer of Shenyang blower group, is at home in Yunfeng street, Tiexi District, Shenyang. The telephone rang suddenly.

However, no one answered the phone. The hostess has been on a business trip, and the hostess is concentrating on completing the thesis on "transplant dynamic anti surge control system", and the outside voice can not enter the world she is addicted to. After studying in the United States for 20 days, Wang Yingjie was determined to digest and assimilate foreign advanced technology, so that the design of domestic compressor and electronic control technology reached the international advanced level.

For more than 10 years, there is little that can stop the senior engineer's enthusiasm for work.

Of course, she is not the only outstanding female of Shen drum. At this time, Wang Guanglan, Zhang Yuzhu, Ge Liling, Yan Hong and other 4 female engineers are also busy for their respective design tasks.

No one can imagine that 5 years later, the first time the 5 outstanding women in the knowledge highlands joined hands to create a surprise of "made in China": We developed our first set of 40 thousand air compressor units to fill the gap in China and end the long history of China's large air compressor's dependence on imports.

The name of "five golden flowers" is spread around the fan industry which is considered to be male. They were only 35 years old at that time.

　　 "Design cannot be kept behind others, you must have something new to surpass."

It was raining at 12 in the evening of August 17, 2004. Large nitrogenous fertilizer plant is being tested in the workshop of Dezhou Hua Lu Heng Sheng company.

When 23 meters long, 4 meters high, weighing more than 1000 tons, and 40 thousand components of air compressors made up of more than 10 thousand components appeared in front of people's eyes, Wang Yingjie and Wang Guanglan, the leading designers, couldn't help breathing. Is this giant thing really our design?

Warm up, speed up, pressure... With the speed increasing of the gas turbine, the whole unit works. A few hours later, the turbine reached its working revolutions, and the unit worked normally.

At this moment, Wang Yingjie, Wang Guanglan, or 3 other "golden flowers" far away in Shenyang, can hardly conceal their ecstasy: 40 thousand, the localization of air compressor units has been successful.

This means that a vast market has opened the door to Shen drum. 48 thousand air separation projects such as air separation and 52 thousand air separation compressor will come to Shengu.

This means that the history of foreign companies monopolizing China's large air compressor market is over.

Previously, the largest compressor in China was only 18 thousand air separation units. Over the past 30 years, China has invested more than ten billion yuan in chemical fertilizer projects. But the key equipment of these projects, large air compressor, is imported from abroad.

By coincidence, this project brought 5 smart women together. The company leaders repeatedly studied, and the 5 leading designers stood out: the 39 year old Wang Yingjie was in charge of the design, audit and coordination of the control system. The 38 year old Wang Guanglan was in charge of the core difficulty -- the design of the air compressor, 39 years old Zhang Yuzhu, 30 year old Ge Liling, and 29 year old Yan Hong 3 female engineers, respectively, responsible for the design of the nitrogen compressor, ammonia compressor and ammonia refrigerator.

"Design cannot be kept behind others. You must have something new to transcend." Wang Guanglan, who has spent 17 years in Shengu, said. Before taking over the Dezhou project, she had designed more than 30 compressors.

The five sisters clearly realized that many technologies of the 40 thousand air compressor unit belong to the forefront of the world's fan field. At present, only a few developed countries have mastered it. The units they design must have different design ideas from foreign products, and they must have their own intellectual property rights.

"From 10 thousand air points to 18 thousand air points is only quantitative change, but from 18 thousand air points to 40 thousand air points is a qualitative change, the technology is different. We couldn't do it before, because some of them were not very mature. Wang Guanglan explained.

Therefore, it is not difficult to understand that when Shen Gu's general manager Su Yongqiang first asked Wang Guanglan to explain his task, she once said, "I'm afraid I screwed up."

As the leading design task of air compressors, Wang Guanglan not only came up with a design scheme with independent intellectual property rights, but also helped users save a lot of money. She has completed the plan put forward by the factory to combine the two machines into two, so as to realize the bold idea of "driving two".

At the same time, she used the bold design of 6 rotors. As a result, the aerodynamic power and power consumption index of the product is less than the world advanced level. The temperature of the cooler cooled by special structure is three or four degrees lower than that of the world advanced level.

"Almost every design step, you must innovate." Other sisters also face technical difficulties. Zhang Yuzhu, who is responsible for the nitrogen compressor design, has selected 4 sets of design schemes, and each set has more than 50 pages. Finally, the best design plan has increased the design level of the nitrogen compressor by a large block.

According to statistics, 40 thousand air separation units have achieved hundreds of technical innovations and more than 20 core technologies have been breakthroughs.

[reporter] in the 70s of last century, Shen Gu started with the technology imported from abroad. Thanks to the efforts of generations of technicians, the original technology has been "thrown away" and replaced by more than 200 new technologies, reaching the international advanced level. Whether it is joint venture or the introduction of technology, it will not fundamentally enhance the core competitiveness of enterprises. Technological innovation is the key to solve the problem of core technology and major equipment being controlled by others.

　　 "Winning the bid depends on comprehensive strength, but cutting edge negotiations are also important."

In fact, Shen Gu's "Dezhou campaign" had been launched long before the signing of the agreement.

In 2002, Shandong Hua Lu Heng Sheng invested 1 billion 370 million yuan to carry out the technical transformation of large nitrogenous fertilizer plant. This is a major scientific and technological tackling project for coal replacing oil strategy in China, and the 40 thousand air separation compressor unit is the "heart" of this device. In July, Hua Lu Heng Sheng officially invited the public bidding.

Wang Yingjie and Wang Guanglan were chosen as "pioneers" by South Korea and Dezhou.

However, their competitors are strong, both multinational and joint ventures.

What is more disadvantageous to them is that Shen Gu only has a "resume" of producing 18 thousand air points, and 40 thousand air points have always been the peak for domestic enterprises. In the fan industry, people are more used to "speaking with results".

"When the user saw Shen Gu's technical expert turned out to be two young female designers, his eyes were somewhat doubtful or even cold." Wang Yingjie recalls. For a long time, this area is usually dominated by men.

"The performance without 40 thousand empty points does not mean that there is no strength." During the day, they smile and make persuasion and exchange work. In the evening, they were at the hostel "picking" the details of the unit performance, process parameters, technical instructions, etc., to prepare for second days of tackling key problems.

In just two months, Wang Yingjie and Wang Guanglan came to Dezhou eight times. They make every technical exchange conscientiously with women's exquisite and sincerity. They made up their minds that even if the negotiations were not successful, they had to help users understand more about technical details, so that users could not negotiate with foreign businessmen.

Gradually, Hua Lu Heng Sheng was moved by the sincerity and momentum of Shen drum, and gradually tilted toward localization.

In the two months, they made more than 30 technical quotations, and the material was printed 4 meters high.

In the end, Shen Gu group got a 84 million yuan purchase contract which would affect its future development.

"Winning the bid depends on comprehensive strength, but frontier negotiations are also important. Today's designers do not have to work hard, but they must also have market awareness and negotiation skills. Wang Yingjie said.

[reporter feeling] in a few years, "Jinhua" not only quickly grew from ordinary technical personnel to the backbone of production technology backbone of the enterprise, and the leading designer of large-scale project design, but more importantly, successfully realized the role change. Instead of being trapped in the study, they are actively involved in the tide of the market economy. They are always thinking about the corporate image. The establishment of market awareness and competition concept changed them from pure technical personnel to expert market pioneers.

　　 "There's nothing that can't be done. There's nothing to eat."

In October 15, 2002, the Liaoning Grand Theater, Shengu group, held a "pledge session" for the Dezhou project.

Yang Zhenfeng, general manager of Hua Lu Heng Sheng, spoke frankly and heavily: "this project may be an image problem for other factories. But for us, it is a matter of life and death. If we screw up, we will disappear in China's chemical industry. "

In fact, this project is also a matter of life and death for Shen drum. Successful, will bring broad market and considerable benefits; failure, the company may never be involved in the chemical industry air separation compressor field.

Only success - Hua Lu Heng Sheng and Shen drum have no choice.

"We have lived under pressure, and we have proved ourselves." Wang Yingjie said. Although she heard that she was the leader of the project, she left the meeting for the time being unable to restrain herself.

Be strong, tough and studious -- these words flash in the evaluation of "five golden flowers" by colleagues.

A little glance at their growth trajectory shows that these evaluations are biased.

As the elder sister of "five golden flowers", Wang Yingjie, director of the instrument control room of Shengu group design department, only had secondary school education when he entered Shen drum. In second years, she was admitted to Northeastern University. When she graduated, she not only got a bachelor's degree in engineering, but also ranked first in the whole department. Today, Wang Yingjie, who is studying MBA, has long been a professorship expert.

Zhang Yuzhu has gone through a similar process. After graduating from the technical school, she was assigned to work as a worker in the workshop. Two years later, she was admitted to Shen Gu staff college, studying turbo compressor specialty, and was assigned to the design department for her excellent results. From the start of a project, she soon became the backbone of technology.

The youngest two "Golden Flower" Ge Liling and Yan Hong graduated from university in 1996 and became the leading designer in 2000. In 2002, they took up the task of "making China".

For the five sisters, the enterprise is a big school, and each item is a test. Shen drum chose them as the leading designers because of their excellent performance in a "test".

After receiving the "test questions" of the Dezhou project, the five sisters had no rest days and no holidays. In only 3 months, they have completed the design task completed by international counterparts in five or six months. This project involves 3 design institutes and dozens of suppliers, but "Jinhua" has successfully completed the coordination work.

In order to make the data calculation accurate and accurate, Wang Guanglan, who is responsible for the design of the air compressor main engine, has been calculating from day to night from the day of accepting the task, and has consulted with the old people with an open mind, and has completed the accurate calculation in more than a month.

Zhang Yuzhu, who is responsible for the nitrogen compressor design, is busy in the factory during the day and needs to work overtime at home in the evening. Her house was almost the second design studio, and the drawings and materials were all over the floor, so that the husband could only sleep on the sofa.

"There's nothing that can't be done. There's nothing to eat." Yan Hong, who is responsible for the main design of the ammonia cooler, has experienced the sharp pain of her husband's death, and has quickly recovered herself. She turned grief into passion for work and made every design part perfect. It took only two months to come up with an excellent design plan.

Despite many difficulties encountered in the design, they were cut off by their efforts and the help of the old experts.

"The compressor is ringing, gold is two thousand". Hua Lu Heng Sheng is very satisfied with the efforts of the five sisters - 40 thousand air separation compressor. They said that if they had to install second sets of equipment in the future, they should be handed over to Shen drum. As for the current set of units, "do your advertising."

[reporter's feeling] until the first time after two months of "oath of assembly" Technical coordination committee On the whole, we found out that the 5 leading designers were all the same women. When he first chose to lead the designer, Shen drum only called the best R & D personnel of each sub unit. Why is "flower" so red? Because they are based on their own efforts and strength. Success is a kind of accumulation.

　　 "Some people can really concentrate on their work. Every day, from morning till night, they can totally ignore it. But I can't do it. "

"Some people can really concentrate on their work. Every day, from morning till night, they can totally ignore it. But I can't do that. " Wang Guanglan said.

Her 15 year old daughter is reading junior three. Wang Guanglan will give his daughter a massage, no matter how late he is, unless he is on a business trip. Squeeze the toothpaste to your daughter and carry the washing water to your daughter's feet.

No doubt, the five sisters are excellent women. Engineer 。 But they are also mothers, wives, daughters and daughter-in-law. They also need to nurture their children, take care of their husbands, and honor their parents.

When receiving the Dezhou project, "five golden flowers" have become mothers. The youngest child is 12 years old, the youngest is less than two years old, and is the time when families need them most.

"The balance between work and family is always in balance. You can't say that you have done a good job, but try to do it. " Ge Liling had some guilt about bringing up his children.

Ge Liling is in 2002 National Day. Design Encountered a "stumbling block", a few days continuous overtime until eight or nine p.m., the brain is full of figures. One day, it was almost nine o'clock in the evening when she remembered to pick up the child.

As a matter of habit, she walked around with her child thinking about the design problem. When she went up the stairs, she accidentally stepped on her foot, and the child and she all rolled down. She protected her child with her mother's instinct, but because of her continuous overtime for several days, she did not even have the strength to carry her child. The frightened child cried and shouted, "Mom, get up!" fortunately, the child did not break.

Like Ge Liling, "five golden flowers" are somewhat ashamed of their families. In order to deliver excellent designs on time, they entrusted their children to their families or nanny. But they never forget their family roles.

During the Dezhou project, it coincided with Wang Yingjie's 66 year old birthday. She asked for half a day's leave, worked in the kitchen for over two hours, and made 3 dishes to entertain more than 30 guests.

Wang Guanglan's daughter loves her mother's dishes. When Wang Guanglan was free, he would not forget to stir fry some dishes.

Similarly, when he was free, Yan hung taught his son quick calculation and Tang poetry. Nowadays, 4 year old son has learned simple addition, subtraction, multiplication and division, and Tang poetry is fluent enough to read simple articles. Ge Liling also takes the time to take the children to do outdoor activities and teach their children to read.

"Different roles can inspire a person's potential in many ways and reflect many aspects of value, while a single role is always incomplete for women." Wang Guanglan said she would rather live under the pressure of "double roles" than lose her femininity.
