yes!

Good bolts, why does it loose during work?

Not only those technical and quality personnel, but even Gu Zhengxin was not included, and wanted to know the reason, so he waved loudly: "Come over with a wrench, take a look at this bolt."

After thinking about it, he simply said: "Click the lights, look at this bolt, take the camera over, and prepare to take a photo."

The camera has been prepared, mainly taking some photos during the test drive process, and also taking photos after problems occur during the test drive process.

The lights came over and the light was very bright. The situation of the bolt in this problem was clearer, and even the area around it was very clear.

The camera was also brought over.

The wrench was also taken over.

Gu Zhengxin said loudly: "Disassemble the bolts and take photos while disassembling them. Be sure to take a picture of the cause of the fault."

This must be taken.

Not only is it a record, but there is also information to query when the fault analysis is conducted afterwards. A technician started to remove the bolt with a wrench. Because it was loose, he removed the nut without any effort. Another technician took a photo with a camera.

He took a photo of what the bolt looked like before removing it. After removing the nut, he also took a photo of what the bolt looked like.

Several other technicians watched the whole process by the side. Others, such as the test runners and other managers, also wanted to come close to take a look, but knew that this would only get in the way, affecting the disassembly of the bolts and taking photos.

They kept a certain distance and were watching the whole process. A little further away was Zhu Chuandong and other leaders, including the director and deputy director of the test workshop. A little further away, there were a large number of onlookers, including workers, technicians, and managers.

The nut was easily removed, and immediately, a burst of exclamations rang out.

How could this happen?

Several technicians were collectively shocked. This was the case. No wonder the bolt loosened and failed during work.

It turned out that the installation of the buckle was missed during the assembly process, which was a very low-level quality accident. Gu Zhengxin had thought about the possibility of loosening and failure of bolts, but he did not expect that this would be the case.

Such a low-level mistake made Gu Zhengxin's face turn blue and very ugly. At this moment, he must be full of anger and wished to tear the assembly worker who made such a low-level mistake alive.

Too hateful!

He actually made such a low-level mistake.

Gu Zhengxin is the chief engineer, responsible for the technical and quality work of the entire factory. He has not encountered such low-level mistakes for a long time, and he is simply furious.

What!

This happened when the bullet pad was missed.

Even these test runners found it incredible. Such a situation is probably rare to encounter twice a year, but it actually happened in a 400-hour long test run.

"This is simply harmful."

"It's too irresponsible and must be severely punished."

“…”

Many workers looked indignant and wanted to find the irresponsible assembly worker and see who he was.

If you make such a low-level mistake, please come out and take two steps.

Zhu Chuandong came over and after learning about the situation, he felt heartless. At least the real reason for the failure was found. He reminded: "Lao Gu, the most urgent task is to resume the test run. As for accountability, you can put it after the test run."

Yes, this is indeed the reason.

At present, nothing is more important than resuming the test drive.

Gu Zhengxin suppressed the anger in his heart, tried to calm his mood, and waved his hand and said loudly: "Come on the bullet pad, reinstall it, and continue the test drive."

Soon, a technician brought the matching pads, installed the gaskets and pads, then installed the nuts on them, tightened them to meet certain torque requirements, and used a marker to make a loose-loose mark.

"Mr. Gu, you can try it again!"

Gu Zhengxin ordered loudly: "Restart the test run!"

Soon, the diesel engine on the test drive table started working again, making a deafening sound.

At the entire scene, no one spoke, and basically no one made any sound. Everyone either pricked up their ears and listened carefully to the sound of the test drive, or looked at the working diesel engine on the test drive table, while the test drive technicians focused on the various instruments and meters of the test drive.

"Report, the noise value is within the qualified range and the vibration value is normal!"

Upon hearing this, Gu Zhengxin felt relieved and raised his hand to look at the time. It took more than 40 minutes from parking for fault checks to resuming the test run, which was completely within the two hours' requirement.

The scene was full of joy!

"I'm so happy that I'm starting the test drive again!"

"I was worried about it just now!"

"I feel relieved when I hear this diesel engine works again."

“…….”

The excited voices of the workers floated in from his ears. Zhu Chuandong quietly breathed a sigh of relief and gradually felt relieved.

The test run continued, moving towards 400 hours.

The workers, managers, and technicians who were watching gradually dispersed, leaving only the necessary people here. Zhu Chuandong and other leaders stayed for nearly an hour before leaving.

Seeing that the test drive was normal, they left with confidence.

At night, the test workshop was brightly lit!

Zhu Chuandong and other leaders of the Hongqi Factory were all wearing thick military coats, undoubtedly absent, and all went to the test workshop.

Gu Zhengxin, who was stuck at the test drive, was stunned at first, and then understood what was going on, saying, "Mr. Zhu, you don't need to stay here, it's the same if you come here tomorrow."

The test drive will not be completed until around 10 am tomorrow. It is OK to come here at that time, and you can see that the 400-hour long test will be over.

Zhu Chuandongdao: "We are destined to be unable to sleep tonight. It's better to stay here and watch the test drive with your own eyes."

The test workshop was very lively throughout the night.

Not only are the leaders of Hongqi sticking to this place, but there are 20 or 30 people here, from the first half of the night to the second half of the night and dawn.

The rising sun rises!

The morning sun shines on the ground, bringing a hint of warmth to the cold northwest region. In the test workshop, everyone is full of energy.

Even after staying up all night, no one was tired. The test drive time has accumulated more than 398 hours, which is not far from 400 hours.

The breakfast was notified to the staff to deliver it directly to the workshop by the chefs in the canteen, and everyone ate breakfast next to the test drive table.

The workers started to work, but they had no intention of working for the time being. Many workers were watching and knew that 400 hours had entered the countdown stage.

Ten:20 minutes in the morning.

Gu Zhengxin raised his hand to look at the time, then looked at the diesel engine on the test drive table that was still working. Suddenly, he felt his eyes a little wet.

Not easy!

Too difficult!

From the processing of parts of the first diesel engine of the 054 ship, to the assembly of the entire machine, to the 400-hour long test run, scenes are displayed in his mind like a movie.

"Report, the cumulative test run time has reached 400 hours!"

The technician in charge of the test drive reported loudly, interrupting Gu Zhengxin's thoughts. After he came to his senses, he walked over and pressed the parking button himself.

On the test drive table, the diesel engine was working stopped, and the entire scene became quiet.

Very quiet!

No one made a sound, his eyes were all looking at Gu Zhengxin.

Among so many pairs of eyes, Gu Zhengxin tried his best and shouted loudly: "The first 400-hour long-term test run of the first diesel engine of the Type 054 missile frigate was a complete success!"

The sound echoed in the test workshop!

After three or five seconds, there was a shocking cheer in the workshop. The entire test workshop was boiling, and everyone shouted and shouted!

Some people even hugged each other and started crying loudly.

Seeing this scene, Gu Zhengxin felt his nose sore. This man in his forties shed two lines of tears!

There was a voice in my heart shouting, we succeed, we succeed!

The first diesel engine of the 054 ship successfully passed the 400-hour long-term assessment test drive!

Gu Zhengxin quietly took out his handkerchief, turned his head, and gently wiped his tears. Suddenly, he saw Zhu Chuandong crying and was also wiping gently there.

The test drive was successful, and many people couldn't help but burst into tears.

This day was January 28, 1995.

It’s only two days before the Lunar New Year.

...........

Donghai Institute.

Yang Fan was reading a technical document, looking at the calendar on the table, thinking to himself that the 400-hour test run of the first diesel engine of the 054 ship should be almost over.

As the chief designer of the 054 ship, Yang Fan is of course very concerned about the test run of the first diesel engine. The successful passing of the 400-hour test run means a big step towards success and the formal production and manufacturing of the first batch of diesel engines can be started.

If the test run fails, it will be more troublesome. You must analyze the reasons for the failure, make rectifications, and then start the test run again, which will take a lot of time.

For the 054 ship, the most precious thing at present is time. The construction of the first ship had begun cutting the first steel plate a few days ago. In about a year, it would require at least four diesel engines, which could not be delayed at all.

If there were no diesel engines, the construction of the first ship of the 054 ship would inevitably stagnate and the impact would be relatively large. Yang Fan did not want to see such a situation happen.

"I hope the Hongqi Factory lives up to expectations and passes the 400-hour long-term test run smoothly."

At about 10:30 in the morning, the phone on the desk rang rapidly. As soon as Yang Fan picked up the phone, Gu Zhengxin, a excited and excited voice from Hongqi Factory, came from it.

"Chief Designer Yang, on behalf of Hongqi Diesel Engine Heavy Industry Group, I will report to you good news!"

When Yang Fan heard this sound, he felt relieved.
