Everyone came out of the power cabin.

It can be seen that everyone was not in high spirits and had worked hard for almost an afternoon, but still couldn't find the root cause of the problem. Li Zhengjun also sighed.

Tired, hot, and not yet harvested.

This is a little frustrating.

The atmosphere was dull and there was no talk until I walked to the deck.

When everyone was surprised, Lu Guodong, Chen Shaohua and others were still waiting there and did not leave. Seeing everyone coming, Lu Guodong noticed everyone's expressions.

He smiled helplessly, as if he was expecting it.

"Let's go, let's go to have a meal first."

As the top leader, everyone has worked hard for so long. He wants to reward everyone, and he has already ordered a meal at a restaurant outside.

Everyone, including Li Zhengjun, looked at Yang Fan and knew that it was benefiting from Director Yang again. If it were not for Director Yang, let alone Lu Guodong came here to warmly invite him to dinner, even Chen Shaohua would not have a high chance of coming here.

At this moment, the obvious relaxation and joy on Yang Fan's face had faded away, and he gradually calmed down, thinking whether the problem was really caused by the alternation of cold and cold.

Thinking seriously, I basically didn't say anything, but my face was calm and I was not as frustrated or heavy as others.

Lu Guodong was really polite. The cars were arranged, with a total of three cars. In addition to his and Chen Shaohua's respective cars, there was also a military-green jeep.

"Everyone get in the car, we go out to eat, and we have worked hard today."

Li Zhengjun showed shame, "It's true that we have worked hard, but we have not found the root cause of the problem. We have a very guilty meal."

"Where, where, I know the problem is difficult, and it is normal not to find the source of the problem for the time being." Lu Guodong replied.

Everyone left the first ship to build the ship platform, left the factory area of ​​the Donghai Shipyard, and stopped at the entrance of a hotel with a good size and environment outside.

When you enter the private room, the air conditioner is very comfortable.

"Oh, it's so cool."

“It feels so comfortable.”

After sitting down, everyone said this. The originally a little depressed and heavy feeling finally got better, and they started to talk and laugh.

The meal was very rich.

But there was no white wine, but the cold and cool thing was like a very comfortable drink. Lu Guodong originally wanted to have a bottle of white wine, but Li Zhengjun insisted that he would continue to board the ship after dinner. Yang Fan had no intention of drinking, so there was no white wine.

After the food was served, as the head of Donghai Factory, Lu Guodong enthusiastically invited everyone to eat their chopsticks. The table was full of people, and the atmosphere gradually became warmer.

The topic of the conversation between everyone was naturally related to this matter. After chatting for a while, Lu Guodong couldn't help but ask, "Director Yang, what do you think is the problem?"

Yang Fan didn't want to say it at first because he was not 100% sure, so he only had some inferences in his mind. Is this the case? He was going to return to the ship after dinner and verify it before talking.

What if your inference is incorrect, that's not the case?

So Yang Fan did not volunteer to express his inferences, but Lu Guodong asked, thought about it, and still said it.

The top leader asked specifically, if it was still hidden in his heart, it would be a little bit unimpressive.

Yang Fan said seriously: "I don't know what the problem is yet, but there are some inferences that I'm going to go on the ship to verify after dinner."

ah!

What!

Lu Guodong, Chen Shaohua, Xie Xinjian and other people from Donghai Factory all looked at Yang Fan in surprise. Some people were probably a little excited.

They know Yang Fan.

I know that if I don’t have certain certainty, Yang Fan would not say that.

Suddenly, the atmosphere became obviously different. The people from Donghai Factory, including Lu Guodong, all their eyes were focused on Yang Fan. After they were slightly stunned, they were also a little surprised and looked at Yang Fan, waiting to continue talking.

Seeing that everyone was looking at him, Yang Fan sorted out his thoughts and said, "I had no idea before, but the changes in the weather have given me some inspiration. Now is the hottest time of the year. At noon, the temperature in the power cabin can reach as high as 40 degrees. At night, the temperature will gradually drop. By the second half of the night, the temperature will probably drop to about 25 degrees."

"Such a large temperature difference, one cold and one heat, has an impact on our shaft system. Everyone knows that thermal expansion and contraction are also adaptable to our power system..."

Gradually, gradually...

After hearing what Yang Fan said, everyone's eyes lit up, and their eyes were simply emitting light!

Li Zhengjun slapped his thigh hard and shouted, why didn't I think of this?

Other technicians said in their hearts that they are so awesome, they deserve to be Director Yang.

Xie Xinjian said excitedly: "It must be this reason, it must be this reason!"

Yang Fan looked at everyone and continued: "Is this the reason? We still need to verify it. Director Lu, this requires your cooperation."

Lu Guodong said readily: "No problem. Director Yang said we will do whatever we want, and implement it unconditionally. Even if I, the factory manager, do whatever I want, I will do it unconditionally."

Yang Fan smiled, "I'm so serious, there's no need for Director Lu to do anything in person, just arrange some work."

"That's what I plan. After dinner, we will verify whether it is really due to hot and cold. The method is very simple. Put a thermometer in the power cabin to record the temperature changes in the cabin."

"As the temperature changes, we measure the deviation of the shaft system. Every time we change, we measure it once. If we find that the deviation of the shaft system exceeds 0.05 mm, we adjust the shaft system to ensure that no matter which temperature it is located, the deviation is within the range of 0.05 mm."

Yang Fan inferred that temperature changes have an impact on the axis system deviation.

If the axis deviation value measured by a certain temperature is qualified, as the temperature changes, it may fail when measured at another temperature.

Everyone understood what Yang Fan meant, and Lu Guodong said: "Arranging technical and quality personnel, starting tonight, we will constantly measure the axis system deviation for me. The staff arrangement is sufficient, and a group of people will be replaced every few hours."

Chen Shaohua, Xie Xinjian, and Zheng Xianxue nodded one after another, especially Zheng Xianxue. He volunteered: "I'll make arrangements, don't worry, everyone."

Things are settled.

After dinner, everyone returned to the Donghai Shipyard as soon as possible and took action soon. Many technical and quality personnel were summoned to hold a meeting first.

The work is arranged and divided into division of labor through meetings.

There were twenty or thirty technical or quality personnel in the conference room. They probably had heard of something. The meeting had not started yet. The conference room was very noisy and everyone was discussing this matter.

"I heard that I found the root cause of the problem."

"Yes, the root cause of the problem has been found, and it was found by Director Yang of the Donghai Institute."

"Oh my God, it's Director Yang again."

"Awesome, so awesome!"

“…”

Everyone was discussing this heatedly, and the buzzing discussion almost reached outside the conference room until Yang Fan, Chen Shaohua, Zheng Xianxue and others walked in.

The originally noisy talk came to an abrupt end!

Everyone's eyes were focused on Yang Fan.

At this moment, Yang Fan's face was calm, and he walked into the meeting under everyone's eyes and sat down in his seat.

Zheng Xianxue presided over the meeting.

First, we introduced Yang Fan's inference, and then divided the labor of everyone, divided these technicians and quality personnel into 6 groups, rotated every 4 hours, and uninterrupted for 24 hours.

After deploying the tasks and completing the division of labor, the meeting will be disbanded.

It took action soon. Soon after, a thermometer was hung in the power cabin, and several technical and quality personnel began to measure the axis system deviation.

Record the measurement time, temperature and axis system deviation values ​​on the table. According to Yang Fan's opinion, every degree of temperature changes must be re-measured and recorded.

After measuring and recording, they were temporarily free and could chat and rest for a while. In less than an hour, a technician reminded him.

"The temperature dropped by one degree, from 31 degree to 30 degree."

"Quick, let's measure the deviation of the shaft system again."

“……”

Several people were busy again, recording the axis system deviation at 30 degrees, and recording the measurement time, etc.

It can be easier for the time being. Just pay attention to the temperature changes. When the temperature drops to 29 degrees, they measure it again and record it.

At this time, it was already past ten o'clock in the evening.

Chen Shaohua, Yang Fan and Zheng Xianxue walked into the power cabin, mainly to see if the measurement results are true as Yang Fan speculated.

Several technical and quality personnel saw several big bosses coming and greeted him actively. Chen Shaohua nodded and asked, "How is the result? Is there any change?"

Several technical and quality personnel looked at me and I looked at you, and their expressions were very strange. It was not until Chen Shaohua asked again that one of the technicians said.

"We measured the deviation values ​​of the shaft system in three temperature environments of 31 degrees, 30 degrees and 29 degrees, but there seemed to be no change."

What!

No change!

This is impossible!!!

Chen Shaohua and Zheng Xianxue's faces changed, and he thought to himself, how could there be no change? This was inferred by Director Yang Fan.

Yang Fan was also puzzled and said in his heart that there should be some changes.

After pondering for a while, Yang Fan said: "Show me the measurement results."

The technician gave the measurement results to Yang Fan, which was a pre-made table, with clear and clear deviations in temperature, time, and axis system.

From this registration form, it can be seen that under three temperature environments, the axis system deviation value did not change, and Yang Fan suddenly became thoughtful again.

How could this happen?
