Chapter 561 The children next door are crying

The members of the bid review team all had blank expressions, and apparently no one knew what an axial compressor was.

Someone said: I know compressors, they are in refrigerators and air conditioners. As for adding the word axial flow, this is the first time I heard that it should not be used in refrigerators and air conditioners. !

Another person said: This is a 2 billion bid. If it is a refrigerator compressor, how can it be written in the bidding document? I think this axial compressor should be something unusual.

Makes sense, I guess it's a newly developed power device, right? the third person said.

Is it electrical equipment? Ask the technical department to find out. Zhu Hongxiang walked over to the phone and dialed the technical department's number.

Hey, is Chief Xia here? I'm Zhu Hongxiang! Zhu Hongxiang said.

Mr. Zhu, Mr. Xia went to the Chinese Academy of Sciences to negotiate. If you are in a hurry, call him! The phone answered.

Negotiation? What negotiation? Zhu Hongxiang asked subconsciously.

I'm going to talk about the use time of the wind tunnel laboratory. The wind tunnel experiment time allocated to us by the Chinese Academy of Sciences is simply not enough, so General Manager Xia went to an acquaintance and hoped to give us two more hours a week. Answered.

Oh, this is an important matter. If it can't be delayed, I won't disturb Chief Xia. Zhu Hongxiang paused, then said, Actually, I don't have any major business, so I can ask you about it. There is an electrical equipment called Axial compressor, you know?

Axial compressor? That's not electrical equipment, the phone answered immediately.

We are an electric power company, not electric equipment, so what are you doing in the bidding document! Zhu Hongxiang couldn't help but complained in his heart.

The phone went on to explain: The axial flow compressor is a large-scale air compressor with a maximum power of more than 100,000 kilowatts and an exhaust volume of more than 10,000 cubic meters per minute.

100,000 kilowatts? According to this, this thing not only cannot generate electricity, but also consumes a lot of electricity! Sending this thing over, do you think our power company has too much electricity to use up!

Zhu Hongxiang pursed his lips, and then asked, Is this kind of axial compressor expensive?

It must be expensive! But I don't know how much it is. This is not something that I can touch at this level.

The man paused, then said: Let me explain it to you like this, you know that to make an atomic bomb, you need to enrich uranium? To separate enriched uranium, you need a centrifuge.

In the field of aerodynamics research, the importance of top-level high-power axial compressors is similar to the centrifuges used to separate enriched uranium when the atomic bomb was built.

Zhu Hongxiang understood such a metaphor in an instant, and he immediately said: That is to say, this axial compressor is still a strategically important equipment! That's really a good thing. What exactly is this axial compressor? what for?

It is mainly used to build wind tunnels. The other party then explained: The wind tunnel laboratory is mainly divided into three parts, the tunnel body, the measurement system and the drive system. The axial compressor is the core of the drive system.

Hearing this answer, Zhu Hongxiang was shocked, and he immediately confirmed: You mean, if there is an axial compressor, a wind tunnel laboratory can be built?

The other party thought for a while and replied, Theoretically, it's like this, the construction of the wind tunnel is not too difficult, as long as it has been carefully calculated in advance and coupled with strict construction standards, it can be built.

As for the measurement system, it is mainly a variety of valves, moving parts, instruments, and sensors to measure airflow parameters and model states through balance, pressure, temperature and other sensors.

Although wind tunnels in advanced countries have been computerized, the rich and the poor have their own methods. If there is no computer, manual and manual data recording can achieve the same effect.

I understand.

After thinking for a few seconds, Zhu Hongxiang asked: There is a lot of demand for wind tunnel laboratories in your R\u0026D department, right?

The phone immediately replied: Of course, there are too many experiments to be done, too much data to be measured, and the time allocated by the Chinese Academy of Sciences is simply not enough.

For example, the development of wind power projects involves aerodynamics, and almost every step is inseparable from wind tunnel tests. For example, the appearance design, material properties, and even the power test of the power generator need to be simulated in advance through wind tunnel experiments.

It is no exaggeration to say that without wind tunnels, the research and development of wind power generation would not be possible at all. In addition, hydropower projects also need to use wind tunnel experiments. Always simulate the situation of the hydropower station being subjected to strong winds!

Now we have completed a lot of work and theoretical research, and the result is stuck in the wind tunnel experiment. Without wind tunnel experiments and without relevant data, research cannot proceed.

I understand! Zhu Hongxiang nodded: It seems that I really have to talk to Chief Engineer Xia in detail.

...

Xia Xuehai walked out of the office building of the Chinese Academy of Sciences with a depressed expression on his face.

He came to ask for the time in the wind tunnel, but he found several leaders and worked as a foreign worker all morning, but he didn't want to come for a minute.

Wind power R\u0026D projects need to use wind tunnels, and other projects also need to use wind tunnels. There are so many scientific research projects in the country that need to be developed, many of which are more important than wind power projects, and the duration of wind tunnels is naturally not enough.

If in 20 years, whether it is low-speed, high-speed, ultra-high-speed wind tunnel, or even shock wave, arc wind tunnel, China can build itself.

At that time, many universities in China had their own wind tunnel laboratories, and the length of the wind tunnel could even be used to train kayakers.

However, in the 1990s, China's technology was still relatively backward, and the experimental time of the wind tunnel was so precious to researchers!

For Xia Xuehai, it was just a waste of time all morning, but he didn't win the time in the wind tunnel, which made his mood drop to the bottom.

At this moment, the phone rang, Xia Xuehai answered the phone, and said Hello in a rather low voice.

Chief Xia, I'm Zhu Hongxiang!

Different from Xia Xuehai's emotional Tillot, Zhu Hongxiang's voice is full of enthusiasm.

Xia Xuehai is even more depressed, I am not happy, you seem very happy! You comrade is very bad!

Zhu Hongxiang said, Chief Engineer Xia, I heard that you went to the Chinese Academy of Sciences for the duration of the wind tunnel experiment. Is it going well?

Which pot can't be opened and mentioned! Xia Xuehai scolded inwardly, and then said angrily: I don't want to come, they won't give it!

That's such a pity. There was no regret in Zhu Hongxiang's tone, but a hint of excitement, which to Xia Xuehai sounded more like gloating.

This Zhu Hongxiang, why is he getting more excited the more he talks, does he really want to see my joke? Xia Xuehai thought to himself.

Zhu Hongxiang went on to say: General Engineer Xia, if it really doesn't work, let's build a wind tunnel by ourselves. Then it will be convenient for you to do experiments. You can do it whenever you want.

I want to build a wind tunnel myself! And I want to make it beautiful! Xia Xuehai said angrily, I said Zhu Hongxiang, are you kidding me on purpose?

It is not taboo for Xia Xuehai to call Zhu Hongxiang by his first name. He is several years older than Zhu Hongxiang, and he is also the chief engineer of the company. His abilities and qualifications are all there. Even if he is chasing the boss of the company, the boss just laughs. Valley

It is no exaggeration to say that the superior department can send someone to replace the leadership of the power company at any time. Anyway, there are people in the power system who are proficient in business management, and there are many people who meet the requirements in terms of ability and qualifications.

But a chief engineer like Xia Xuehai can't just send someone to take on the heavy responsibility. Those who can be the chief engineer of the National Electric Power Company may not be able to find the number of them in the whole country.

In the professional field, all qualified high-level intellectuals must make offerings as bodhisattvas.

So being called by Xia Xuehai's name and called you boy, Zhu Hongxiang didn't dare to get angry, he quickly said with a smile: Chief Xia, don't be angry, I'm not here to help you solve the problem!

That's fine, go and help me get a two-hour wind tunnel. If you can come, I'll invite you to dinner, you can choose the place! Xia Xuehai said bluntly.

If you don't come, how can I have that ability. Zhu Hongxiang continued; Let's talk about building a wind tunnel, shall we?

You don't even want to come to the wind tunnel for two hours, so you are still talking about building a wind tunnel here? Xia Xuehai felt more and more that Zhu Hongxiang was here to make fun of himself, and he continued: If you build a wind tunnel for me , let me support you for the rest of my life!

Don't, it sounds like someone is taking advantage of who. Zhu Hongxiang said quickly; If you really can build a wind tunnel, just invite me to drink a good bottle of wine.

If you can really build a wind tunnel, I treasured six bottles of Maotai in 1982, and you can take them all. Xia Xuehai said.

Isn't it Lafite in 1982? Forget it, Maotai will do it... Zhu Hongxiang underestimated a sentence in his heart, and then said, Chief Xia, let's make a deal!

Okay, don't sell it when it's cheap, hurry up and get down to business! Xia Xuehai thought that Zhu Hongxiang was gossiping with him just now.

Zhu Hongxiang said, Isn't our company going to sell Taifeng and Taisheng mines, the bidding process has been completed. Originally, the company planned that the two mines could be sold for 1.8 billion yuan, but as a result, there were several bidders, and the quotations given were all Over two billion!

The bidding is a company secret, don't tell me the specifics, it's too much trouble to know! Xia Xuehai said cautiously.

Okay, then I won't say the amount, but the other conditions offered by the bidder. Zhu Hongxiang continued: There is a bidding company that, in addition to funds, is also willing to provide us with a high-power axial compressor.

You mean axial compressor? Xia Xuehai almost screamed.

Yes, it's an axial compressor, the kind used to build wind tunnels, Zhu Hongxiang said.

Then what are you waiting for, agree to it! Xia Xuehai said eagerly.

General engineer Xia, it's not up to me to decide who wins the bid. It has to be decided collectively by the company's leadership team.

Zhu Hongxiang paused, then said: And I don't know what this axial compressor looks like. I don't know if this axial compressor is real or fake if I don't go to the field to investigate!

It makes sense, but I'm in a hurry. Xia Xuehai continued: You wait for me, I'll go back right away, let's meet and discuss in detail!

...

Of course, the power company must first confirm whether Dongshan Mining can really provide an axial compressor.

So the two sides made an appointment to inspect the goods.

In a large warehouse, Xia Xuehai looked at the huge fan with a regretful expression.

Why is it rusted! It would be great if it wasn't rusted! Xia Xuehai sighed softly.

Don't worry, Chief Engineer Xia, it's just that the fan blades are rusted, and they are painted with a layer of paint, which is like brand new, and the axial compressor at the back is still good. Li Weidong quickly introduced.

Naturally, two other engineers were checking the axial compressor.

After a while, the engineer finished the inspection, and then reported to Xia Xuehaihui: Chief Xia, there is no problem with the axial compressor. Although there is some lack of maintenance, it does not affect the normal operation. It can be used after a good repair.

Another engineer also said: This is an axial compressor produced by the Soviet Union in the mid-1980s. The workmanship is very good, the materials are abundant, and it is particularly durable.

This axial compressor basically represents the highest industrial level in the former Soviet Union. If Russia is now, it is not necessarily possible to make products of this quality.

The mechanical products produced in the Soviet Union may not be as good as European products in terms of performance, may not be as refined as Japanese products, and may not be as technologically advanced as American products, but in terms of porcelain, they are absolutely unmatched.

For example, many domestic enterprises still use the machinery and equipment of the Soviet Union in the 1950s in the 1990s.

On the streets of Cuba in 2021, you can also see many classic cars from the 1950s and 1960s in the former Soviet Union are still speeding.

It is precisely because the Soviet machinery and equipment are so durable that this axial compressor has been stored in the warehouse for several years and can still be used.

Of course, it is also related to the simpler structure of the axial compressor.

In the eyes of later generations, the axial compressor is the simplest type of wind tunnel drive system. This thing is almost purely mechanical, with little or no electronic control.

Purely mechanical things often have a relatively long service life, such as mechanical clocks, if they are properly maintained, they can still turn after hundreds of years.

This axial compressor has been left in the warehouse for so many years. In addition to lack of maintenance, the biggest problem is the aging of the line.

After returning to China, Li Weidong also took great care to repair it. Although the important parts could not be replaced, there was no problem in replacing a few aging wires.

So in the hands of Li Weidong, this axial compressor was rejuvenated.

...

Xia Xuehai couldn't hide his joy when he learned that the axial compressor could still be used.

With this axial compressor, we can build our own wind tunnel laboratory. At that time, it will take a long time to go to the Chinese Academy of Sciences to ask grandpa to worship grandma! When the wind tunnel is built, give me three In a few years, I will be able to come up with a new generation of wind turbines!

Thinking of this, Xia Xuehai couldn't help feeling surging. He seemed to see that in the vast northwest, rows of wind turbines were dancing with the wind!

Xia Xuehai stepped forward with excitement on his face, looked at the axial compressor seriously, and then carefully stroked it with his hands, like a gentle and elegant old man, with a sane appearance, but in fact he was greedy!

Tick!

A liquid fell on the surface of the axial compressor. It was not tears of excitement, but saliva from Xia Xuehai.

Although it was not wrapped and fried until golden brown, Xia Xuehai was already crying!
