Siheyuan: Starting from the driver

Chapter 782 The final battle

The installation process was lengthy and stressful.

Every gear, whether it's the driving gear, the driven gear, or a complex planetary gear set, undergoes a series of rigorous processes, including cleaning and measurement.

Yi Zhonghai watched from afar, his feelings complicated.

On the one hand, as the maker, seeing the parts he had painstakingly created being so cherished and meticulously assembled filled him with a deep sense of craftsmanship pride.

On the other hand, seeing Li Kailang, this "young upstart," as the commander, receiving everyone's attention and expectations, he felt bitter and resentful.

He closed his eyes, not wanting to look anymore.

Even the workers who had been scolded and told not to come in by Ling Gong were watching from the workshop entrance. Although they couldn't enter, they could still see the scene from the doorway.

Qin Huairu stood on the outskirts of the crowd a little further away, but her gaze always followed Li Kailang's tall and straight figure.

Watching him calmly and confidently issue orders among a group of experienced masters and technicians, the composure and the radiance of his knowledge warmed her heart.

Looking again at Yi Zhonghai, who lay emaciated in the corner, she gripped the hem of her clothes tightly, and a thought became increasingly clear:
I must find a way to get close to him, even if it's just to say a few words.

Yi Zhonghai's path is ultimately becoming narrower and narrower.

We need to make plans sooner rather than later.

By the time the last gear was installed and all the connecting bolts were tightened to the specified torque, it was nearly evening.

"All installation points have been inspected and meet the process requirements!"

Director Sun looked at Engineer Ling and Technician Li, his voice trembling with anticipation: "Engineer Ling, Technician Li, shall we give it a try?"

The workshop fell silent instantly, and dozens of eyes focused on the newly installed grinding machine and Li Kailang.

Ling Gong looked at Li Kailang: "Xiao Li, you're in charge. Tell me, can we test drive it?"

Li Kailang met everyone's gaze and nodded calmly: "Test run is possible, Engineer Ling. According to the procedures, conduct an unloaded test first."

"Good!" Engineer Ling waved his hand. "Prepare for test run! Director Sun, activate the safety plan. All unauthorized personnel, retreat behind the safety line! Technical team, complete the monitoring and recording!"

The worker switched on the special power switch, and the operator took a deep breath and solemnly pressed the start button.

Om-!
A low, steady sound of the motor starting up rang out, followed by the slight friction and meshing sounds of the transmission system beginning to operate.

The sound rose from low to high, then gradually stabilized.

No-load operation begins!
Everyone's hearts were in their throats.

One minute, two minutes.
The motor runs smoothly, the transmission system operates smoothly, and the gear meshing sound is crisp and even, without any abnormal friction, impact, or sharp noise.

Everything is within the normal range.

The vibration value was also far below the alarm threshold.

"The sound is normal!"

"Vibration amplitude 0.05mm/s, excellent!"

……

Ten minutes later, Li Kailang ordered: "Increase speed without load!"

The operator did as instructed.

The grinding machine's operating noise increased slightly, but it remained stable and orderly.

"First gear RPM is normal!"

Fifteen minutes later, "Speed ​​up again!"

The grinder emitted a deep, powerful roar, yet remained stable.

"Second gear RPM is normal!"

Twenty minutes later, "Speed ​​up again!"

The grinding machine continued to operate smoothly.

"Third gear RPM is normal!"

The 30-minute no-load run has ended.

The grinding machine is still in good working order!

Next, we will perform a loading test.

This is the most important thing.

A rough-machined workpiece is carefully clamped on the worktable of a grinding machine.

The atmosphere was even more somber than during the no-load test run.

The operator's forehead was even beaded with sweat.

start up!

laugh--

The grinding wheel rotates at high speed driven by the motor, emitting a sharp and steady whistling sound.

The worktable begins to move slowly and precisely according to the set program, bringing the workpiece closer to the high-speed rotating grinding wheel.

laugh--!
The grinding wheel emitted a piercing grinding sound the moment it came into contact with the workpiece.

"Monitor all points and pay attention to any changes!" Engineer Ling ordered in a deep voice.

Everyone's eyes were fixed on the grinding machine turning.

For the first few minutes, everything was under control.

The grinding sound was stable, and the parameter fluctuations were within the normal range.

Li Kailang stared intently at the surface of the workpiece being ground, watching as the metal shavings were evenly peeled away, gradually revealing a bright metallic luster.

"Increase the feed rate by 10%," Li Kailang calmly instructed the operator.

The grinding sound became even more intense.

But everything is within safe limits.

One minute, two minutes.
Ten minutes passed, and the workpiece gradually began to take shape.

"It's done! It's done!"

I don't know who shouted first.

"Whoa—!" A huge cheer erupted in the workshop, almost lifting the roof off!
The workers in the workshop patted each other on the shoulder, their faces beaming with long-lost joy and relief.

This is not just about fixing one piece of equipment; it's about removing a huge worry from their workshop and even the entire steel rolling mill!
"Great, great, great!" Director Sun's face was flushed. With this grinding machine, the workshop and the workers could finally relax!
Many tasks and workpieces no longer need to be done repeatedly!

"Technician Li! Well done!"

A relieved smile appeared on Ling Gong's serious face, and he patted Li Kailang's shoulder heavily:

"Well done, Xiao Li! Solid theoretical foundation, rigorous practical operation, and excellent command! Truly a promising young talent!"

Li Kailang maintained a humble smile: "This is the result of everyone's joint efforts."

Everyone's eyes involuntarily turned to Yi Zhonghai.

"Yi Gong! Awesome!"

"An eighth-grade worker, that's truly impressive!"

"Thank you for your hard work, Yi Gong!"

Faced with a flood of praise, Yi Zhonghai forced a smile onto his tired face and tried to straighten his back, which had been hunched over for five days.

It was worth the five days and five nights of suffering!

He subconsciously looked at Li Kailang, his eyes filled with complex emotions.

He humbly replied, "It's my duty, it's my duty. If the factory needs me, I have to do it."

However, amidst this jubilant atmosphere, the technician who had been closely monitoring the data frowned slightly.

He noticed that during the final high-speed no-load phase, although the overall data was acceptable, the readings of a certain high-frequency vibration sensor showed a few minor anomalies.

He glanced at the excited crowd, then at the few negligible peaks on the record sheet, hesitated for a moment, and ultimately did not report immediately.

After all, it's rare to succeed, so let's make everyone happy.

Li Kailang was not blinded by excitement.

This grinding machine has many problems, and he has only solved one of them. There are still several problems that he hasn't solved yet.

Immediately, they had to pour cold water on the idea.

"It's an honor to be able to solve the problem smoothly, but this is only one of the problems with the grinding machine. There are still a few problems that haven't been solved." "My abilities are limited for now. The other problems will have to be solved by everyone."

The cold water was very effective, and everyone gradually calmed down.

Director Sun waved his hand: "It's alright, if we can solve one, how far away is the next one? I have confidence in you, right everyone?"

The workers responded loudly in agreement.

"That's right!"

"Exactly, Technician Li is so young, how could he not solve other problems?"

"Yes! That's exactly right!"

Director Sun added, "This grinding machine wasn't really broken to begin with. Technician Li has already fixed one problem, so the machine is finally usable again."

Seeing this, Li Kailang didn't say anything more. "Try it out in the next few days, and let me know as soon as you have any problems."

"Yes, yes, Technician Li is right. The revolution is not yet complete, comrades must continue to strive!"

After this battle, Director Sun had more confidence in Li Kailang.

Besides, I also didn't want to leave this grinding machine idle any longer.

Just looking at it without being able to use it makes my heart itch; who could resist?

With Li Kailang's abilities, there will always be a day when everything is resolved.

Upon seeing this, the technician stopped himself from saying what he was about to say once again.

He also gained more confidence in Li Kailang. As for the problems, he would report them later.

Since Director Sun and the workers had already said so, Engineer Ling and Li Kailang couldn't afford to discourage them further.

However, he still gave a few words of advice not to overdo it, and then left with his people.

Director Sun didn't forget his main task; after machining the workpiece, he still had to inspect the grinding machine and the workpiece.

"Report! All gear backlashes have passed inspection!"

"The workpieces are all within the required standards!"

All tests were within requirements, and the grinding machine has not had any problems.

Director Sun's worries were finally put to rest.

The next day.

It's not over yet.

Now that the grinder is fixed, it's time to finish up the rest.

He wrote down his insights from studying the historical maintenance reports of grinding machines during this period, as well as his detailed review of this installation process, and submitted them to Engineer Ling.

First, of course, we must not forget to ask questions.

"The gear set was successfully installed and ran perfectly under no-load conditions. However, a high-precision grinding machine is a complex system, and gear issues are only one aspect of the problem to be addressed."

"Historical records show that there are still problems or potential hidden dangers in its hydraulic system and guide rail precision."

Now that the problem has been raised, a solution is naturally needed.

"First, strengthen daily inspections, paying particular attention to these areas."

"Secondly, when processing the first piece, it is essential to conduct rigorous precision testing and record the results."

This report is not only professional and responsible, but it also foreshadows potential problems in the future.

He won't solve all the problems at once; that would be too "divine" and too fast.

What he wants is a steady, long-term approach, consolidating his position and gaining greater trust and resources by "solving problems" time and time again.

After completing the draft report, Li Kailang did not immediately hand it over to Engineer Ling, but instead went to the workshop to check on the grinding machine.

Along the way, it was naturally surrounded by workers. Some workers were already using the grinding machine, and there were several finished workpieces nearby.

"Master, how's it going? Is the grinder working well? Do you notice anything wrong?"

"No, no, I'm fine. I feel much better than before!"

"Really? That's great! If you encounter any problems, please let me know! I'll take care of it as soon as possible."

"Okay, okay, I'll leave it to Technician Li then."

Seeing that Li Kailang had come back to inquire and check made the workers feel very gratified.

This young technician, who had just made a great contribution, was not only unpretentious but also incredibly approachable.

at the same time.

Qin Huairu, who had secretly run away, finally got her chance.

She had been waiting outside the workshop for a long time, and finally Li Kailang came over.

Seeing that he was about to come out, Qin Huairu quickly straightened her work clothes, put on the most gentle and natural smile, and walked over gracefully.

"Xiao Li, busy?" Qin Huairu's voice was deliberately gentle as she met his gaze.

When Li Kailang saw that it was Qin Huairu, he was surprised and a hint of understanding flashed in his eyes.

"Is there anything I can help you with, Master Qin?"

Hearing this address, Qin Huairu felt a little disappointed.

She used to call me sister-in-law or Sister Qin, but now she's calling me master. It's making me feel more and more unfamiliar with her.

Qin Huairu was not discouraged. She took two steps forward and struck a relaxed yet dignified pose.

"Xiao Li, we really owe you a lot for fixing that machine this time. You've been working so hard these past few days, it really breaks my heart."

"It's all part of my duty," Li Kailang replied briefly, his tone indifferent.

"It's good that you people are cultured," Qin Huairu sighed, her eyes filled with just the right amount of envy and a hint of melancholy.

“People like us work ourselves to the bone in the factory just to make a living. Unlike you, you can solve big problems with a little brainpower, and even an old man has to take your orders.”

"Going to university really makes a difference."

She tried to elevate Li Kailang through comparison, while implying that her own life was difficult, in order to gain sympathy.

Li Kailang looked calmly at Qin Huairu, as if he could see through the intentions behind her carefully crafted words.

Qin Huairu felt a slight panic when he looked at her, and almost lost her smile.

"Master Qin, both work and learning have their own hardships and intricacies. Anyone who can do their job well deserves respect in any profession. I have other things to attend to, so I'll be leaving now."

Li Kailang was unwilling to linger with this widow, lest people gossip about him.

Qin Huairu's smile froze completely on her face, a hint of embarrassment and awkwardness creeping into her heart.

Her carefully prepared probing was like punching cotton, with no leverage whatsoever.

Watching Li Kailang's tall and straight figure walk away, Qin Huairu bit her lip, her eyes flickering. After the sense of defeat came resentment and an even stronger desire.

The more unapproachable he was, the more alluring he became in her eyes.

After returning, Li Kailang continued to refine the draft of the report.

The grinding machine has only been running for one day, so we should wait at least two more days to confirm that there are no problems before submitting the report.

Li Kailang will have some free time these next couple of days.

"hateful!"

Looking at Li Kailang, who seemed relaxed and carefree at his workstation, Engineer Liu gritted his teeth in hatred.

The intention was to give him a difficult task and embarrass him, but unexpectedly he succeeded and fixed the grinder.

This was completely different from what he had initially expected!

Unexpectedly, this incident actually boosted Li Kailang's reputation even further!
"If I had known he would succeed, I would have joined in!" Several assistant technicians secretly regretted.

At first, no one believed that Li Kailang could succeed, and everyone adopted a wait-and-see attitude.

Now that Li Kailang has actually succeeded, they are starting to feel a little regretful.

After all, joining them would greatly benefit their resumes.

If Xiao Zhao, Huang Jin, and He Yu were to participate.

He could have been promoted to a permanent position within a year, maybe even three months earlier, though Li Kailang did it much earlier.

No one is sharing credit for Li Kailang's achievements now.
