For a moment, the scene was very quiet.

No one spoke, no one made a sound, only the sounds that came from the two technicians when they disassembled the transmission shaft. Many people were originally full of confidence, but at this time they were uncontrollable and a little nervous.

Time seemed to have solidified.

It was not long before, but everyone felt that it seemed that it had been a long time since it was cooler and not hot in the power cabin. Many people began to feel the heat and started to sweat.

Finally, the bearing shell was removed.

Suddenly, many people felt relieved, and the originally quiet power cabin also became noisy, and they couldn't help but squeeze forward, hoping to see the situation of the bearing shell.

"How about it?"

"It should be no wear or anything like that."

“…”

Because the space is relatively limited, it is impossible for everyone to see the bearing shells and cannot see the specific situation. They couldn't help but ask this.

Chen Shaohua, Xie Xinjian, Zheng Xianxue, Li Zhengjun and others leaned forward, focusing their eyes on the bearing shell.

Zheng Xianxue is a skilled person. He squatted down and looked at it carefully. He also touched the smooth surface of the bearing shell with his hand, and his expression became a little serious.

A heart slowly sank...

"Old Zheng, what's the situation?"

Xie Xinjian couldn't help but ask.

Zheng Xianxue sighed, his tone very heavy, "Although it was much better than last time, it still had slight wear."

What!

Many people were shocked and then suddenly became cold!

There will also be wear and tear.

Whether it is severe wear or slight wear, those who work on technology know that it is actually the same, because the test run time is only more than twenty minutes, and the entire power system is idle.

On the vast sea with a wide range of weather, sometimes it has to sail at high speed, sometimes it has to reverse, and sometimes it has to sail for several days and nights.

Slight wear will occur after just over twenty minutes of the test run, which is definitely not possible. As long as the time is longer, the slight wear will become severe wear, and the bearing shells may even burn, which will not meet the requirements of sea navigation at all.

Chen Shaohua also looked at the situation of the bearing shell and said nothing for a long time.

The atmosphere on the entire scene became invisibly dull and depressing, and there was no longer the ease and hope that just now.

Tonight is destined to be a sleepless night for the entire Donghai Shipyard.

After hearing the news, senior leaders such as Lu Guodong and Zhang Guoxin all came, entered the power cabin in person, and saw the situation of the bearing shell with their own eyes.

The technicians at the Donghai Shipyard began to check the root cause of the problem, and they all night long. There were many people in the power cabin, and even after dawn, they were still the same.

.........

East China Sea Ship Design Institute.

Yang Fan was reading a book in his office. When he saw Han Jiang pushing the door and immediately put down the book in his hand, he looked surprised.

"Why did you do this? Didn't you sleep all night last night?"

Han Jiang smiled bitterly, "Almost, I only slept for three or four hours last night. Do you know? Donghai Shipyard failed the second test drive last night..."

He briefly said the situation.

Upon hearing this, Yang Fan was shocked and stood up, "No way, the second test drive has worn the bearing shell again, how could this happen?"

This was really beyond Yang Fan's expectations.

Yesterday I learned that Li Zhengjun, deputy director of the power system design office, took several technicians to the Donghai Shipyard. To be honest, Yang Fan felt much more relieved.

Once he once speculated that Li Zhengjun went there, and there should be no problem with the second test run of the first ship, because he knew that Li Zhengjun was a very strict person and would probably ask the Donghai Factory to adjust the axis system deviation to 4 wires, or even within 3 and a half wires.

Surprised, Yang Fan asked about some of the situation at that time, then thought about it and said nothing for a long time.

Han Jiang stood up, yawned, and said loudly: "Anyway, this is the situation. I'm so sleepy. I have to go back and have a sleep first."

Watching Han Jiang leave, Yang Fan was thinking in his mind, but he didn't know what the reason was. Maybe he needed to go there in person and see the situation.

I raised my hand and looked at the time. It was almost noon. It was unrealistic to go to the Donghai Shipyard immediately. I could only finish lunch and go there in the afternoon, or just go there early tomorrow morning.

After get off work at noon, Yang Fan did not ride a bicycle, but walked, walking towards home while thinking about the wear of the bearing shell.

I reached the door of my house, and this time I came to my senses, smiled silently, temporarily threw this matter behind me, and pushed the door into the house.

The meal has just been prepared, and Li Xiuzhen's credit.

She basically lives here, takes care of Jiang Yan, helps with housework, and prepares the meals every day, which makes Yang Fan much easier.

"Mom, thank you for your hard work again."

"Where?" Li Xiuzhen said happily, "I'm not working hard at all. Come and wash my hands and eat. Today I made sweet and sour pork ribs, you can try it."

Li Xiuzhen has good skills, especially a few dishes that are well-made, including the sweet and sour pork ribs that Yang Fan likes to eat.

Yang Fan nodded and did not see Jiang Yan in the living room. He knew that she was sleeping in the bedroom or reading a book, so he shouted, "Wife, I'm having dinner."

Then he walked towards the bedroom. Sure enough, Jiang Yan was reading a book. He probably heard the movement. He had put down the book in his hand and said with a smile: "I've eaten again, so I'll be like a fat pig."

Yang Fan smiled happily, "You are a pregnant woman now. You should eat more, even if you eat more weight, I like it too."

After saying that, his eyes fell on the book Jiang Yan was reading.

She is still a professional book on accounting, she majored in accounting in a secondary school. She has been reading it for more than ten days and looks like she has almost finished reading it.

Yang Fan asked, "How is it? I'll have a lot of rewards after reading this book."

"Yes." Jiang Yan nodded, "Your suggestion is correct. Let's start with the simple ones and proceed step by step. Fortunately, this is the case, otherwise if it is too profound, I can't hold on."

Yang Fan gently supported Jiang Yan.

Jiang Yan said: "It's okay, I don't need to help me, I can leave myself."

She is only over 6 months pregnant and her belly is not very big. She can walk by herself. Yang Fan supports her, but she just cares about it.

During this period of time when Jiang Yan was at home, he was bored. In addition to going out for a walk, he mainly reads books or sleeps at home.

It should be influenced by Yang Fan that she has become more and more fond of reading books, and even read professional books on accounting. In her words, after she is born, she will be ready to help Sister Fang, start with the most basic accounting.

The three of them sat down for lunch.

Yang Fan picked up two sweet and sour pork ribs into Jiang Yan's bowl, and then picked up one into Li Xiuzhen's bowl, "Mom, you eat it too."

Li Xiuzhen was so happy that she couldn't stop talking and said quickly, "No need to pinch it, I'll do it myself."

She was becoming more and more satisfied with this son-in-law and helped with housework. Although she was a little harder, she was very happy to do housework and was full of energy.

......

Go to work in the afternoon.

I was originally considering whether to go to the Donghai Shipyard to take a look, but not long after I entered the office and sat down, Chief Secretary Pan called me.

"Xiao Yang, come to me."

After putting down the phone, Yang Fan quickly knocked on the door and entered Pan Jinfu's office. As soon as he came in, he saw Chen Shaohua. He was slightly stunned and a little surprised.

Chen Shaohua is here?

At this time, he should stay in the Donghai Shipyard and work with their technicians to check the problems, find out the problem, and solve the problem.

Although I was a little surprised, I did not show any of my face, but smiled and said loudly: "Chief Pan, please look for me."

Then, he greeted Chen Shaohua again, "Mr. Chen, you are here."

Pan Jinfu waved his hand to signal Yang Fan to sit down, and then said with a serious look on his face: "The second test of the power system failed again. Xiao Yang, you heard about it."

Yang Fan nodded, "I heard about it."

Chen Shaohua even explained the situation in more detail, which was more detailed than what Han Jiang said today.

After introducing these situations, Chen Shaohua frowned and said in confusion: "We have adjusted the axis system deviation to less than 0.035, but there are still bearing shell wear. The entire technical system of our Donghai Shipyard is confused and the reason has not been found yet."

He sighed softly and continued: "We have not found the root cause of the problem so far. Some technicians doubt whether there are defects in the design, which leads to such problems."

Design defects???

Yang Fan smiled confidently and was very familiar with the power system of the 052 ship. Almost most of the important and key design drawings were checked by him personally. How could there be design flaws?

It is an excuse to say that some technicians at Donghai Factory have this suspicion, probably not some, and even Chen Shaohua himself may have this suspicion.

It's just not easy to say it clearly, it's just some technicians.

Pan Jinfu pondered for a moment, then said, "There is no possibility of design flaws. Let's do this. I'll see it tomorrow morning, Xiao Yang will go over and take a look."

He attached great importance to Yang Fan and knew that his level was high. The key was that many of the design drawings of the power system were checked by Yang Fan. Yang Fan was very familiar with the power system of the 052 ship.

Director Yang went to help take a look!

Gradually, Chen Shaohua's eyes became eager, and he wanted to slap his thighs, and said in his heart, "Yes, why did I forget Comrade Yang Fan?"

Alas, I was so anxious and confused. I actually forgot such a great god. Damn it, damn it!

I remembered in my mind that Yang Fan helped Donghai Factory solve a large number of problems, some of which were not as difficult as the current problem.

Gradually, gradually...

Chen Shaohua's eyes became more and more eager...

Yang Fan smiled and thought to himself, Mr. Chen, your eyes are so warm that I can't stand it.

Chen Shaohua ignored these things, as if he had grabbed a life-saving straw, holding Yang Fan's hand tightly, and said a little excitedly: "Director Yang, then we will count on you."

Yang Fan said modestly: "Don't, I'm still good at designing the power system. When I go to Donghai Factory, I just look at the problem from the perspective of design. I'm not sure where the problem lies."

"Director Yang, you are too modest." Chen Shaohua said.

It can be seen that he did not believe that Yang Fan did not know what the problem was, but was full of confidence in Yang Fan.
