Chapter 410 Life-saving straw
After asking by phone, Yang Fan knew that Dongjiang Shipyard had not yet come up with a solution. From yesterday to today, time has been wasted in vain.
Originally, he did not intend to interfere in this matter. Yang Fan believed that Dongjiang Shipyard had a strong technical team and they should be able to solve this problem.
But that's not the case.
It seems that I can't stand by and watch, I have to help them figure out a solution. After Yang Fan thought about it this way, he picked up the phone and called the model.
"Get the design drawings of the power system and the installation design drawings of the spindle to my office, and I want to take a look."
The person who answered the phone was Li Zhengjun. He quickly took over the design drawings he needed and placed them on the large table that specifically reviewed the design drawings. He asked curiously: "Chief Yang, is there something wrong with the power system?"
Yang Fan replied: "We have no problem with our design, but there was a quality problem during the construction process of Dongjiang Shipyard..."
I briefly told the situation.
Suddenly, Li Zhengjun's face changed slightly. He was the deputy director of the power system design room before. He knew the importance of the spindle mount, but now it is actually 3 mm in deviation. This problem is too serious.
"Chief Yang, what should Dongjiang Shipyard do?"
Yang Fan said: "So far, they have no choice. Let me think of a solution to them and see if this problem can be solved."
Li Zhengjun nodded softly, understood what was going on, and said softly: "Then I'll go out first, call me if you need anything."
Regarding whether Chief Yang can solve this problem, Li Zhengjun's opinion, this is not a problem at all. Chief Yang will definitely have no problem.
Yang Fan said: "You go and do your business. I need to take a good look at these design drawings first."
The design plan for the entire power system was decided by Yang Fan, but the specific design was completed by the technicians below. Yang Fan needs to take a good look at some specific designs.
Spread out the design drawings and read them carefully.
While looking, he thought, after reading for a full twenty or thirty minutes, Yang Fan picked up the pen and paper, drew a sketch, and then calculated the formulas, which were full of several large pages.

Dongjiang Shipyard.
There was a problem with the power system spindle mounting seat, which was a major quality accident for them. The whole factory did not dare to relax at all. The problem was not solved yesterday, and today the technical analysis meeting continued. Unlike yesterday, some technicians from the Donghai Institute attended the meeting.
Wang Bo is the head of the technical team of Donghai Institute in Dongjiang Shipyard and a design supervisor. He was previously a deputy team leader of the power system design office and is very familiar with the power system of the 054 ship.
The technical minister of Dongjiang Shipyard personally introduced the situation and said: "Director Wang, do you have any good suggestions?"
Wang Bo reminded: "The power system spindle mount is quite good. Now that such a problem occurs, I have no good solution for the time being. What about you?"
The technical minister said: "We have a plan, but it must be approved by your design department, which is to add an eccentric bushing into the bearing mount."
Add an off-center set?
This is a way...
Through the correction of the eccentric bushing, the bearing mounting hole can be kept in a straight line with other mounting holes of the spindle, and can meet the process and design requirements in terms of straightness requirements.
Wang Bo thought about it for a while and said very cautiously: "If you add a bushing, there are many problems, such as how much interference is, what kind of process is used, and complex strength calculations, etc."
Is it so complicated?
Many technicians were startled and looked at each other.
They originally thought this plan was feasible, but as long as the design agreed, the problem would be basically not big.
Wang Bo said: "I won't discuss this method for the time being. Let's think about it again, is there a better way."
The meaning is very obvious. If you do not have to consider this plan unless you have to.
For Wang Bo, this seems simple, but it is actually very complicated, especially involving a lot of calculations. It cannot be neglected at all, because the spindle transmits such a large amount of power and rotates at high speed in this bearing seat. Once there is a little problem, it is a very serious problem.
He was cautious and did not dare to adopt such a plan.
Is there any other solution?
The technicians began to analyze and discuss again, and the meeting was very intense...
.........
Capital.
Although Luo Jianguo returned to the capital last night, he was always concerned about Jiangdong Shipyard and wanted to call him to ask if the problem has been solved.
But Sun Baoguo did not call him on his own initiative. He knew that the problem was still not solved. Perhaps the Dongjiang Shipyard was in trouble.
He wanted to pick up the phone several times, but he still let it go gently. He knew that he could only wait patiently in this situation.
I had already thought about it in my mind. If no news came to me tomorrow, he would call and ask, what was going on.
If they need any help, they must try their best to meet them. They can even seek relevant experts across the country to solve this problem together.
In the office.
Yang Fan also thought of several solutions, and after careful thinking and even complex calculations, they were basically denied, and only one solution was feasible.
After thinking about it again and calculating again, Yang Fan already knew that there was no better way than this.
Soon, I knew it.
I basically know how to solve this problem.
Putting down the pen in his hand, Yang Fan thought to himself, at this time, Dongjiang Shipyard has not come up with a solution to the problem, and how do they plan to solve the problem?
After raising his hand to look at the time, Yang Fan decided to go to Dongjiang Shipyard in person. If they have come up with a solution, they will keep a close eye on their plan. If they are still helpless, they will recommend that they adopt my plan.
He picked up the phone and told Li Zhengjun that he was going to Dongjiang Shipyard. Then, Yang Fan went out and drove to Dongjiang Shipyard.
I got familiar with the passage and went straight to their office building.
After locking the car, Yang Fan went straight to the office building and soon arrived at the door of Sun Baoguo's office. Seeing that the door was closed, he simply pushed the door open and went in.
"Hey, there's no one inside."
Just as he was slightly surprised, when he wanted to ask someone, he probably heard the movement. Someone came over and he knew Yang Fan.
"Chief Yang, please look for Mr. Sun."
"Yes, I'll look for him." Yang Fan replied.
The man said: "Mr. Sun is attending a meeting in the technical department, I will take you there."
Yang Fan said: "No, I'll tell me which conference room I'm in, I'll just go there myself."
There is no need to lead the way. Yang Fan is very familiar with Dongjiang Shipyard. As long as he tells him the place, he knows how to get there with his eyes closed.
Not long after, Yang Fan arrived at the door of this conference room.
Hearing the movement inside, Yang Fan said: "It seems that the meeting was held very fiercely. Are you discussing how to solve the problem of eccentricity of the bearing seat position?"
It should be.
Yang Fan gently pushed the door and walked in. The meeting, which was originally very intense, gradually stopped. Sun Baoguo even stood up to greet him and shook hands with Yang Fan tightly.
"Chief Yang, you're here just in time."
In addition to enthusiasm, Sun Baoguo seemed to have caught a life-saving straw. They were helpless and didn't know what to do, Yang Fan appeared.
Yang Fan looked at the situation in the conference room and asked with concern: "How is the progress? Have you come up with a solution to the problem?"
If Dongjiang Shipyard already has a solution, Yang Fan is not ready to talk about his plan, but to take a look first.
If their plan is not good, is imperfect, or is not as good as their own, and with the attitude of being responsible for the first ship, Yang Fan will come up with his own plan.
But he knew that Sun Baoguo shook his head with a wry smile and said in great pressure: "So far, we don't know how to solve this problem."
What!
There is still no effective way for so long.
Yang Fan was slightly shocked.
Sun Baoguo continued to be under great pressure and said, "We are anxious. Commander Luo is still waiting for the result in the capital. I don't dare to call him."
The problem has not been solved, and it is really difficult to call.
Yang Fan nodded gently and sat down at Sun Baoguo's invitation. The meeting continued. Gradually, Yang Fan frowned.
