The two arrived at the Dongjiang Shipyard together and stopped at the gate. Sun Baoguo was already standing there warmly to greet him.

Yang Fan lowered the car window.

Sun Baoguo walked over enthusiastically, "No need to enter the factory, let's have a meal first, Chief Commander Yang, follow my car."

Yang Fan nodded and saw Sun Baoguo's car parked not far away.

The two cars left one after another, first went to a nearby restaurant for dinner, had a rest, and then went to Sun Baoguo's office to sit down, had a tea, and then went to the construction platform of the first ship together.

Luo Jianguo saw the first ship under construction for the first time. Although he couldn't see anything on his face, his mood was slightly aroused!

He thought to himself that the first ship had begun construction of the ship platform and it seemed to be progressing well.

Sun Baoguo pointed to the first ship under construction and happily introduced: "Commander Luo, we are welding the various sections..."

He introduced the construction situation.

The Type 054 missile frigate is divided into three general sections according to the modular construction process of the main section. The central general section is first built on the ship platform.

This general section consists of several segments, which consists of its segment lifting, butt and welding, and everything is in order.

After listening to the introduction, Luo Jianguo nodded with satisfaction and asked: "Are there any difficulties in the construction process? What do we need to coordinate?"

Sun Baoguo was secretly happy, waiting for this sentence.

"Commander Luo, we hope that the things from the supporting factory will be delivered earlier. Some equipment will also start to be installed simultaneously when the main section is manufactured. Once the three main sections are manufactured, once they are closed, large equipment will not be able to enter."

This is true at all.

Luo Jianguo also knew this well and said loudly: "The General Command will pay attention to the supporting situation and require each supporting factory to send each equipment according to the node."

After pondering for a moment, he asked with concern: "It seems that it won't take long, and the first ship will start to install the power system."

Luo Jianguo is most worried about the diesel engines of Hongqi Factory. As far as he knows, the first four diesel engines are still in production and have not yet been assembled.

Sun Bao Guodao: "At most three months, we will start installing diesel engines."

Three months!

Luo Jianguo felt relieved and thought to himself that in three months, Hongqi Factory should be fine. He would call Hongqi Factory later and ask them to complete the delivery of the first batch of diesel engines as soon as possible.

After thinking for a while, Luo Jianguo said with concern: "During the construction process, how is your quality control? No problem has occurred."

The construction progress of the first ship is very important, but the quality is even more important.

Sun Baoguo replied: "We have always been strict with quality. So far, there are no major quality problems. Of course, there are still small problems, but we have discovered them in time and carried out rectification in time..."

As the report was reported like this, the person in charge of the shipbuilding construction came over and looked not relaxed.

Yang Fan first noticed his face and thought to himself: "Is there any problem?"

There should be a problem!

However, when the person in charge saw that Commander Luo was here, hesitated a little. Should he expose the problem to Commander Luo?

Sun Baoguo finally noticed something about the person in charge and asked in a deep voice: "What's wrong? Is there anything wrong?"

The person in charge wanted to speak but stopped, and even looked at Luo Jianguo.

Something must have happened!

Suddenly, Sun Baoguo felt a little embarrassed and couldn't bear to worry about his face!

I just said that there was not much problem during the construction process. I haven’t finished it for a long time. Is there really a problem?

"What the hell is going on? Commander-in-Chief Luo is not an outsider."

The person in charge reported: "Mr. Sun, there is a problem with one of the bearing mounts of the power system spindle. If it is offset by 3 mm, the spindle may not be able to pass through."

What!

The deviation reached 3 mm!

Sun Baoguo's expression suddenly changed. This is a big problem, a serious quality problem!

The 054 ship uses dual-spindle propulsion technology, and the length of each spindle reaches dozens of meters, which requires each installation hole and bearing mounting seat to be kept in a straight line, which has high requirements for straightness.

If the straightness does not meet the requirements, the main axis that is several tens of meters long cannot pass through. Even if it passes through, because the straightness is relatively poor, it will definitely have an impact in future use.

Realizing the seriousness of the problem, Yang Fan's originally calm face became solemn.

Sun Baoguo wanted to get angry and wanted to criticize the person in charge severely.

Yang Fan reminded: "Mr. Sun, let's go and see the specific situation first."

The person in charge looked at Yang Fan with gratitude.

Luo Jianguo also agreed: "Comrade Yang Fan is right, let's take a look at the specific situation first."

Under the leadership of this person in charge, the three of them got on the construction platform and entered the power compartment of the 054 ship, and saw the specific situation.

The current 054 ship has multiple segments connected and welded together, and the power cabin is about to take shape, but it has not yet reached the installation of power equipment.

Everyone saw the bearing seat with offset at that location, where there were already several technical and quality personnel.

Sun Baoguo asked in a deep voice: "How is the situation? Have you figured out the reason?"

A technician replied: "When manufacturing in segments, I guess I misread the drawings, resulting in a 3mm error."

Read the drawings wrongly!

This is a low-level error!

Sun Baoguo's face looked a little ugly and he wanted to get angry, but he knew that the most urgent thing was to solve the problem. If he lost his temper, he could wait a moment before losing his temper.

"Have you discussed the solution?"

Several technicians were quite embarrassed, and this problem was difficult to solve.

The technician in charge said: "Mr. Sun, if you find this problem in the segmented manufacturing workshop, it will be easier to deal with. Now it is the stage of shipbuilding construction, and it is very troublesome to deal with it."

The road is ready!

It was discovered too late.

Sun Baoguo said loudly: "I don't care, I must deal with the problem as soon as possible."

"yes."

“We will do our best.”

Several technicians answered in uneven times, and it was obvious that they generally lacked confidence.

How to deal with such a problem?

Yang Fan was also thinking, feeling that it was difficult and difficult to solve, and it was too late to find the problem.

If the bearing mount of the power spindle has a position deviation, what method can be used to solve this problem?

Is it a way to cut?

Cut off this bearing installation and weld a new bearing mount?

Obviously not!

It is now the construction stage of the ship platform, the space in the cabin is limited, and large-scale cutting equipment is obviously unable to enter, and the mount is very thick, so cutting is by no means easy.

what to do???

The atmosphere on the scene was a little dull.

Several technicians were checking the situation and racking their brains to think of solutions to the problem. Sun Baoguo's face looked a little bad. Commander Luo finally came here, but such a problem actually arose.

Yang Fan had no good plan for a while, and suggested: "Three cobblers, one Zhuge Liang, I suggest you hold a technical analysis meeting and everyone will discuss and solve this problem together."

It seems that this is the only way.

Sun Baoguo nodded with agreement.

Luo Jianguo's mood seemed not to be affected by this, and he waved: "Let's leave it to our technicians, let's go and take a look elsewhere."

The three of them left the power cabin, got off the construction ship platform, went to the sectional manufacturing workshop to see the welding situation of each section, and then went to the discharge workshop to see the steel plates and steel.

Putting aside the problem just now, overall, Dongjiang Shipyard is still very good, and Luo Jianguo is very satisfied anyway.

Due to time, he is going to return to Beijing. He needs to go to the airport at 6 pm.

Before leaving, Luo Jianguo held Sun Baoguo's hand and praised: "Your work is done well. I don't think there is much problem with the construction of the first ship within the specified time."

After praising him a few words, he reminded him: "There is a deviation in the bearing seat position. You must hurry up and solve it. After the problem is solved, call me to tell me."

Sun Baoguo hurriedly said, "Okay, we will definitely solve this problem as soon as possible."

He shook hands with Yang Fan and Sun Baoguo, then got into the car arranged by Dongjiang Shipyard and headed to Donghai International Airport.

After seeing off Sun Baoguo, Yang Fan also drove back to the Donghai Station.

How to solve the problem of bearing seat?

The technical director of Jiangdong Shipyard personally held a technical analysis meeting, and many technicians discussed this issue together, and Sun Baoguo personally attended the meeting.

Until I got off work in the afternoon, I couldn't come up with an effective solution.

Sun Baoguo was in a bad mood and gave an order that within three days, the technical system must come up with a solution to this problem. If it cannot be solved within three days, he will hold the relevant personnel accountable.
