Chapter 212 Really Unqualified

This was really beyond Yang Fan's expectation.

In just one day, Donghai Shipyard successfully installed the main gun. How is this possible?

Well aware of the difficulty and cumbersome installation, Yang Fan is [-]% sure that there must be something wrong with Donghai Factory, and he must point it out.

If there is really a problem with the installation of the main gun, once there is a war on the sea with great weather in the future, such a main gun with a problem with the installation may cause the ship to be destroyed.

Anxious.

He left his office in a hurry, walked out of the office building quickly, and didn't need to go to the trolley class to apply for a car to take him to Donghai Shipyard, but drove by himself.

After opening the door and getting in the car, the JEEP large off-road vehicle let out a low growl, left the Donghai Ship Design Institute, and headed for the Donghai Factory.

It just so happened that someone saw this scene, and his heart tensed invisibly, and he thought a little worriedly, what happened?
Yang Fan didn't care what other people would do if they saw it. At this moment, all he had in mind was the main cannon that had been installed on the Donghai ship. The speed was so fast that he arrived in front of the office building of Donghai Shipyard in less than four or ten minutes.

A sudden brake, the tires rubbing against the ground made a sharp sound, the car hardly stopped completely, and Yang Fan got out of the car.

He strode into the office building quickly, and soon arrived at Chen Shaohua's office. As soon as he entered, he asked: "Old Chen, you have really installed the main gun, tell me quickly, how did you install it at the beginning?" of."

I didn't ask in detail on the phone just now, and Chen Shaohua didn't elaborate. Yang Fan didn't know the specific installation details, so he had to ask now.

Sensing the worry and anxiety in Yang Fan's tone, Chen Shaohua, who was originally in a good mood, sank slightly, "Why, is there really a problem?"

Yang Fan nodded and said, "According to my guess, there may be a problem with [-]% or [-]%."

what!
Really problematic!
Chen Shaohua's heart sank again.

If someone said that there is a problem with the installation of the main gun, he would not believe it, and would even refute it. There must be no problem with our installation. After the installation, we carefully measured the relevant installation dimensions, and the process error was within the allowable range.

But Yang Fan said so, the situation is different.

Who is Yang Fan!

His current identity is the assistant to the chief designer of the 052 ship. Leaving aside this identity, Chen Shaohua is very clear about Yang Fan's technical level.

It's over, it's over.
It seems to be a joyous occasion, there is actually a problem with the installation of our main gun
Chen Shaohua's heart sank gradually, almost to the bottom of the valley. He already thought that there must be something wrong with the installation of the main gun, even though he hadn't measured the relevant installation dimensions yet.

"So what do we do now?"

Chen Shaohua asked anxiously, looking at Yang Fan almost for help.

What's next?
In this regard, Yang Fan's thinking is very clear. The first step is to measure the installation size of the main gun and the specific error of the installation process.

He waved his hand and said, "Come on, let's build the berth and arrange for someone to measure the installation size of the main gun."

"Okay, then let's go now."

Chen Shaohua immediately agreed, and they left the office with Yang Fan, and they arrived at the construction berth not long after. From a distance, they saw many people on the bow deck of the 052 ship.

It seemed to be Zheng Xianxue, Li Chaolin, and Xie Xinjian, the deputy chief builder, who seemed to be talking about something.

The closer the distance, the clearer the sight, and confirm that it is them.

Chen Shaohua waved his hand and said, "Come on, let's board the ship and go to the berth deck."

On the deck, next to the main gun, besides Zheng Xianxue, Li Chaolin and Xie Xinjian, there were several technical quality personnel and several workers.

The main cannon landed steadily on the installation base yesterday, aligned the positioning holes, and tightened the positioning screws, but a lot of installation work has not been completed.

Today, we will continue to install and complete the installation of some things. Only then can the main gun be completely installed.

But in everyone's opinion, the key first step has been completed, and today's installation has almost no technical difficulty, and it should be completed smoothly.

Zheng Xianxue was a little worried, and came here with Li Chaolin, and happened to meet Xie Xinjian, the deputy chief builder who spent almost every day building the berth.

What Zheng Xianxue meant was to measure the installation dimensions again, and confirm again whether each installation dimension is within the acceptable range of the process.

But Li Chaolin thinks it is unnecessary, this move is a waste of time, and the most urgent task is to finish all the follow-up installation work.

Seeing Chen Shaohua and Yang Fan approaching, they stopped the argument.

Xie Xinjian, the deputy chief builder, said: "Old Chen, you came just in time. Minister Zheng wants to measure the installation size again, and you come to make a decision, whether you really measure it again."

It is not easy to measure it once, and several technical quality personnel have to be busy for more than half an hour, because there are many installation dimensions that need to be measured.

Li Chaolin also said: "Mr. Chen, that would be a waste of time, and it's completely unnecessary."

Chen Shaohua looked at Yang Fan, then at Zheng Xianxue, and thought in his heart, Minister Zheng was also worried about the problem with the installation, so he thought about it with Comrade Yang Fan.

"Comrade Yang Fan, what do you mean?" Chen Shaohua said.

Yang Fan looked at the main gun, and then said with a straight face: "I think Minister Zheng's decision is correct, and I am also worried that there is a problem with the installation of this main gun."

What, there is a problem with the installation!
Li Chaolin retorted: "It is impossible to have a problem with the installation. After the installation, we measured the installation size, and it is completely within the acceptable range of the process."

The technical and quality personnel next to it also said in unison, "Yesterday, we measured together. There will be no measurement errors. The installation dimensions at that time were completely qualified."

Yang Fan shook his head lightly.

"Qualified at the time does not mean that it is qualified now. The steel plate of the 052 ship is thinner than the traditional warship steel plate and must be affected by temperature changes. As far as I know, the installation hole diameter of the main gun mounting base is very precise, and the size tolerance It is very small, and the influence of temperature must be considered.”

It's temperature again!

Some people can't help but think of the installation of the power system a few months ago.

Those technical and quality personnel looked at each other, exchanged glances quietly, and saw the solemnity in each other's eyes.

It can be seen that they think what Yang Fan said is reasonable, and then there is a kind of worry in their hearts.

Is there really a problem with the installation of the main gun?
Chen Shaohua waved his hand and said, "Measure again immediately."

After the chief builder said so, and Yang Fan raised the impact of temperature changes, these technical quality personnel took measuring tools and began to prepare for hands-on measurement.

Yang Fan raised his hand and said, "It's not necessary to measure all the installation dimensions. It would be a waste of time. Bring the drawings and I'll tell you which two dimensions to measure."

One of the technicians immediately spread out the design drawings, Yang Fan pointed to two important and critical installation dimensions and said: "Just measure these two dimensions."

These two dimensions are very important.

There is a bracket behind these two sizes, and the words "Z101" and "Z102" are marked in the brackets.

The capital letter "Z" is the abbreviation of the important size. Anyone who is skilled in technology knows that this letter is marked after the size, indicating that this size is an important size.

These technical and quality personnel looked at Yang Fan in admiration, feeling a sense of complacency in their hearts.

As expected of Yang Fan!
It's so powerful, I caught the crux of the problem at once!

He seemed to be very familiar with this design drawing. After the drawing was spread out, he didn't need to look for it at all, and pointed out the two dimensions at once.

This level of familiarity is really rare!
They looked at Yang Fan again in admiration, and then several people took the measuring tools and began to measure. The scene fell silent, waiting for the measurement results.

Li Chaolin felt that he was a little inexplicably nervous.

His intuition seemed to be telling him that these two important installation dimensions might not be acceptable.

No, no.

We carefully measured them yesterday, and they are qualified. How could they become unqualified overnight?
Soon, the measurement results came out.

The leading technician in charge looked bitter, shook his head and said, "Mr. Chen, Assistant Mr. Yang, these two dimensions are really unqualified. This is the measurement result."

After finishing speaking, he gave the recorded measurement results to Yang Fan and Chen Shaohua, and the others gathered around one after another, their eyes falling on these two measurement results.

Really substandard.

The process requires that the error of the butt joint of the main gun and the base should not exceed 0.2 mm, and the error of these two important butt joint dimensions exceeds 0.2 mm.

Failed!
Many people's faces changed, and their hearts sank to the bottom.

At this time, Li Chaolin had no choice but to give in, sighed softly, and thought in his heart, as expected of Yang Fan, he said he was unqualified, he was really unqualified.

Really level!

I was wrong, very wrong!

Li Chaolin lowered his head, with a look of shame on his face.

As the chief builder, Chen Shaohua felt a little heavy and a little disappointed. He thought that the main gun was installed successfully, but he didn't know that there was a problem.

At the same time secretly rejoicing.

Thanks to Yang Fan!

If it weren't for Yang Fan, we would have thought that the installation of the main gun was qualified, but we didn't know that there was such a big installation quality problem.

Xie Xinjian, the deputy chief construction engineer, was basically in the same mood. While feeling lucky, he held Yang Fan's hand gratefully, "Thank you, thank you so much!"

"If it wasn't for you, we would still be happy that the main gun has been successfully installed." Xie Xinjian expressed his gratitude, and then humbly asked for advice.

"Comrade Yang Fan, since the installation of the main gun is unqualified, what should we do? If we reinstall it, how should we install it again?"

Almost everyone looked at Yang Fan, waiting for Yang Fan's advice.

Today is the third update, and the third update is over, thank you everyone!
Ask for all kinds of support, monthly tickets, recommendation tickets, collections, etc. are all available.
