Chapter 561 The children next door are crying

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

Someone said: I know about compressors. They are found in refrigerators and air conditioners. As for adding the word axial flow, this is the first time I've heard of them. It shouldn't be used in refrigerators and air conditioners. !

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

That makes sense. I guess it must be a newly developed electric device? the third person said.

If it's electrical equipment, just ask the technical department. Zhu Hongxiang walked to the phone and dialed the number of the technical department.

Hello, is Mr. Xia here? I'm Zhu Hongxiang! Zhu Hongxiang said.

Mr. Zhu, Mr. Xia has gone to negotiate with the Chinese Academy of Sciences. If you are in a hurry, just call his cell phone! The phone replied.

Negotiation? What kind of negotiation? Zhu Hongxiang asked subconsciously.

It's to talk about the length of use of the wind tunnel laboratory. The wind tunnel experiment time allocated by the Chinese Academy of Sciences is simply not enough, so Mr. Xia went to find an acquaintance, hoping to give us an extra two hours a week. The other party Open your mouth and answer.

Oh, this is an important matter. I can't delay it. I won't bother Mr. Xia. Zhu Hongxiang paused, and then said: Actually, I don't have any serious matters. You can ask you about this matter. There is a kind of electric equipment called Axial compressors, you know that?

Axial flow compressor? That's not electrical equipment. The phone answered immediately.

We are a power company, not power equipment. Why write it in the bidding document! Zhu Hongxiang couldn't help but complain in his heart.

On the phone, he continued to explain: The axial flow compressor is a large air compressor with a maximum power of more than 100,000 kilowatts and a displacement of more than 10,000 cubic meters per minute.

One hundred thousand kilowatts? According to this, this thing not only cannot generate electricity, but also consumes a lot of electricity! Sending this thing here, 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 the exact amount, I don't know, this is not something that I can touch at this level.

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

In the field of aerodynamics research, the importance of top-level high-power axial flow compressors is similar to that of centrifuges for separating enriched uranium when building atomic bombs.

Zhu Hongxiang understood such a metaphor instantly, and he immediately said: That is to say, this axial flow compressor is still a strategically important device! That is really a good thing. Then this kind of axial flow compressor is specifically what for?

It is mainly used to build a wind tunnel. 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 startled, and he immediately confirmed: You mean, if you have an axial compressor, you can build a wind tunnel laboratory?

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

As for the measurement system, it mainly consists of various valves, moving parts, and instruments, and measures airflow parameters and model states through sensors such as balances, pressure, and temperature.

Although the wind tunnels in advanced countries have already been computerized, there are ways for the rich and for the poor. If there is no computer, the data is recorded manually and manually.

The same effect can be achieved.

I understand. Zhu Hongxiang thought for a few seconds, and then asked: Is there a great demand for wind tunnel laboratories in your R\u0026D department?

Immediately answered on the phone: 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 research and development of wind power projects involves aerodynamics, and almost every step is inseparable from wind tunnel tests. Such as appearance design, material properties, and even the power test of the main engine, also need to be simulated in advance through wind tunnel experiments.

It is not an exaggeration to say that without a wind tunnel, the research and development of wind power generation cannot proceed at all. In addition, hydropower projects also need to use wind tunnel experiments, so it is always necessary to simulate the situation of hydropower stations under strong winds!

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

I understand! Zhu Hongxiang nodded: It seems that I really need to talk to Mr. 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 duration of the wind tunnel, but in the end, he found several leaders and spent a whole morning working abroad, but he didn't ask for a minute of duration.

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.

Twenty years later, whether it is low-speed, high-speed, ultra-high-speed wind tunnels, or even shock wave and arc wind tunnels, China can independently build them.

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

However, in the 1990s, China's technology was still relatively backward, and the length of wind tunnel experiments was extremely valuable to scientific researchers!

For Xia Xuehai, it was nothing more than wasting a whole 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 picked up the phone, and said Hello in a low voice.

President Xia, I'm Zhu Hongxiang!

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

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

But Zhu Hongxiang said, Mr. Xia, I heard that you went to the Chinese Academy of Sciences to ask for a wind tunnel experiment. Are you going well?

Which pot will not be opened and which pot will be lifted! Xia Xuehai cursed secretly in his heart, and then said angrily: If you don't want it, I won't give it to you!

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

This Zhu Hongxiang, why does the more you talk, the more excited you become, and you really want to see me laugh, don't you? Xia Xuehai thought to himself.

Zhu Hongxiang went on to say: Mr. 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 by myself! And it's a beautiful idea! Xia Xuehai continued angrily, I said Zhu Hongxiang, are you kidding me on purpose?

Xia Xuehai didn't shy away from calling Zhu Hongxiang by his name directly. He was several years older than Zhu Hongxiang, and he was also the chief engineer of the company. His abilities and qualifications were all there. Even if he challenged the company boss, the boss would just laugh.

It is not an exaggeration to say that the superior department can send someone to replace the leadership team of the power company at any time. Anyway, there are many people in the power system who are proficient in enterprise 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 casually to take on important responsibilities. Those who can work as the chief engineer of the State Power Corporation may not be able to find a handful of people across the country.

In the professional field, all qualified high-level intellectuals must be worshiped as bodhisattvas.

So when Xia Xuehai called him by his first name and was called Your Boy, Zhu Hongxiang didn't dare to get angry, he quickly apologized and said with a smile: President Xia, don't be angry, I'm here to help you solve the problem!

That's fine, you go and ask me for a two-hour wind tunnel. If you can come, I'll treat you to dinner, and 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?

You don't even come here for a two-hour wind tunnel, and you're 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 me a wind tunnel , let me support you for the rest of my life!

Don't, this sounds like someone is taking advantage of someone. Zhu Hongxiang said quickly; If you can really build a wind tunnel, you can buy me a bottle of good wine.

If the wind tunnel can be built, I have six bottles of Moutai in 1982, and you can take them all away. Xia Xuehai said.

Isn't it Lafite in 1982? Forget it, Moutai will let it go... Zhu Hongxiang underestimated something in his heart, and then he said, Boss Xia, let's make a deal!

Okay, don't get cheap and act like a good boy, hurry up and get down to business! Xia Xuehai thought that Zhu Hongxiang was chatting 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 in packages. As a result, there were several bidders, and the quotations given were all More than two billion!

The bidding is a company secret. Don't tell me the details. It will be troublesome if you know too much! Xia Xuehai said cautiously.

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

You mean the 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 quickly! Xia Xuehai said eagerly.

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

Zhu Hongxiang paused, then continued: And I don't know what this axial-flow compressor looks like. I don't know if this axial-flow compressor is real or not unless I go to the field for inspection!

It makes sense, I was too anxious. Xia Xuehai continued: You wait for me, I'll go back right away, let's talk in detail after we meet!

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 on his face.

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

President Xia, please don't worry, it's just the fan blades that are rusted. After a coat of paint, it's as good as brand new, and the axial flow compressor behind it is still good. Li Weidong quickly introduced.

Naturally there were two other engineers checking the axial compressor.

After a while, the engineer finished the inspection, and then reported to Xia Xuehaihui: Mr. Xia, the axial flow compressor is fine. Although it is a bit lacking in maintenance, it does not affect the normal operation. It can be used after going back to repair it.

Another engineer also said: This is an axial-flow 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 of the former Soviet Union. If it is Russia now, it may not be 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 good as Japanese products in terms of refinement, and may not be as technologically advanced as American products, but in terms of porcelain, they are absolutely second to none.

For example, there are many enterprises in China. In the 1990s, they still used the machinery and equipment of the Soviet Union in the 1950s.

On the streets of Cuba in 2021, you can also see many classic cars from the 1950s and 1960s of the former Soviet Union still speeding. It is no exaggeration to say that after seeing this car in the 2000s, it is not too much to call grandpa.

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

Of course, holding it is also related to the relatively simple structure of the axial flow compressor.

From the perspective of later generations, the axial flow compressor is considered to be the simplest type of wind tunnel drive system. This thing is almost purely mechanically constructed, with little need to rely on electronic controls.

Purely mechanical things tend to have a relatively long service life. For example, mechanical clocks and watches can still turn after hundreds of years if they are properly maintained.

This axial flow compressor has been thrown in the warehouse for so many years. Apart from lack of maintenance, the biggest problem is the aging of the circuit.

After it was shipped back to China, Li Weidong also took pains to repair it. Although the important parts could not be replaced, it was no problem to replace a few aging wires.

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

Xia Xuehai couldn't hide his joy when he learned that the axial compressor was still working.

With this axial flow compressor, we can build our own wind tunnel laboratory. Then we don't need to go to the Chinese Academy of Sciences to ask grandpa and grandma for a long time! When the wind tunnel is built, give me three In a year, I will be able to produce a new generation of wind turbines!

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

Xia Xuehai walked forward with an excited face, carefully looked at the axial flow compressor, and then stroked it carefully with his hands, as if he was a gentle and refined old woman who looks sanctimonious, but is actually greedy for someone's body!

Tick tock!

Some liquid fell on the surface of the axial flow compressor, it was not tears of excitement, but Xia Xuehai's saliva.

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

No pop-up window, timely update!
