Siheyuan: promoted to engineer at the beginning, wife Fatty

The New Year is just over a month away.

All departments of the Red Star Rolling Mill are rushing to the task, catching up with the schedule, and are busy.

Lu Cheng was also busy, but he was free

As the top technical personnel in the factory

General technical problems do not require his intervention

Unless the other technicians in the factory can’t solve it, he will make a move

Therefore, I have been quite idle lately, and I can do what I want.

“Haha, it’s done!”

Lu Cheng put the miniaturized lead-acid battery successfully developed into the place where the battery was installed in the electric wheelchair

Connect the positive and negative poles of the battery

Then sit in the electric wheelchair and start operating the wheelchair

It was a little rusty at first

But soon became proficient, forward, backward, turning, lying flat, sitting up.

Lu Cheng was testing and debugging at the same time, and the electric wheelchair became more and more fluent, and he felt that he could take it and give it to his future mother-in-law.

“Huh! Director Lu, why are you in a wheelchair, are you okay, don’t scare me!” ”

Suddenly, there was a shocked voice from Director Yang behind him.

Lu Cheng controlled the electric wheelchair to turn around flexibly, and saw Director Yang come in with a surprised and concerned face

After all, Lu Cheng is the baby in the factory, and it is impossible not to worry about being in a wheelchair suddenly.

“Haha! Director Yang, you don’t have to worry, this is an electric wheelchair designed and developed for Reba’s mother, with this electric wheelchair, she can also move by herself without being pushed! ”

Director Yang breathed a sigh of relief, “Can this car really move on its own?” ”

“Look!” Lu Cheng began to flexibly control the electric wheelchair in front of Director Yang.

Let Yang Factory grow up and open his eyes, and he is also eager to try, “Director Lu, this electric wheelchair you designed and manufactured is really flexible, I also want to control it?” ”

“Okay!” Lu Cheng stood up and taught Director Yang how to control an electric wheelchair.

“All right! I will! I’ll try! After Director Yang finished speaking, he sat down and began to operate.

At first, I was a little nervous and busy

Lu Cheng reminded him how to operate on the side, and Director Yang was able to control it slowly, and said excitedly

“God! This electric wheelchair is really flexible, your future mother-in-law must like it after trying it, Director Lu, you are really a genius, everything can be designed and manufactured, I am really curious about how your brain is different from us! ”

Lu Cheng secretly exclaimed ashamed, “I’m also a hobby, just tinkering with it casually!” ”

“It is not a genius to make such a good thing casually, our Red Star Rolling Mill can be regarded as a treasure!”

By the way, I’m curious about what your electric wheelchair is powered by! I also know that it is electricity, guess you use lead-acid batteries, but the lead-acid batteries I have seen are very large, I see your wheelchair, there is no place to install such a large battery! ”

Lu Cheng said with a smile: “Director Yang is really insightful, you are right, it is a lead-acid battery, but I changed the lead-acid battery to a smaller and put it in an electric wheelchair!” ”

Director Yang suddenly realized, and said with a surprised look, “Can it be made smaller?” ”

“Yes!”

“How small it is, I want to see!”

Lu Cheng took it apart and showed it to Director Yang.

“It was actually converted so small?” Director Yang was shocked.

“Can it be mass-produced? Although I couldn’t think of anything useful for a while, it would definitely be useful! Director Yang exclaimed.

“For the time being, some key components, are imported from abroad, so it restricts mass production, if you want to achieve mass production of small batteries, you also need to localize key parts, it takes time and process!” Lu Cheng said.

It is not that Lu Cheng is selfish, the reason why he did not choose to hand over the miniaturized lead-acid battery to the state is because this technology does not have a great effect on national defense, but it is better to stay in the hand to cash out exports to earn foreign exchange, earn foreign exchange funds, and then invest in research and development, forming a virtuous circle.

If a polymer lithium battery is developed, the role of national defense will be greater.

With polymer lithium batteries, it can provide unmanned power, and then the national defense strength will be a great leap forward.

As for how to use miniaturized lead-acid batteries to make money, Lu Cheng already has a preliminary idea, and there is a chance left.

When he got off work, Lu Cheng carried an electric wheelchair out of the office, and before he took two steps, Zhang Xiaojun, the nephew of Director Yang, ran over and grabbed the electric wheelchair to carry it.

“Thank you!” Lu Cheng smiled.

It attracted a lot of attention along the way.

“What is it?” Zhang Xiaojun, why are you carrying a wheelchair with Director Lu? ”

“This is an electric wheelchair made by Director Lu, which can be moved by itself!” Zhang Xiaojun grinned.

“Electric wheelchair? Do it yourself? The first time I heard about it, I didn’t expect Director Lu to make this kind of thing, it’s really powerful! ”

The factories looked amazed.

Lu Cheng tied the electric wheelchair to the back seat with a rope, “Xiaojun thank you!” ”

“Hee-hee! Director Lu, you are polite, my uncle said, let me get closer to you and learn from you! Zhang Xiaojun grinned.

It was a humble brat, Lu Cheng laughed and encouraged Zhang Xiaojun a few words before leaving.

Came to Reba’s house.

Not long after Reba came back, he was pleasantly surprised to see Lu Cheng carrying a wheelchair, “This is an electric wheelchair?” Made it? ”

“yes!”

“My godmother must love it! I’ll push her out! ”

It didn’t take long for the godmother to come out.

Seeing an electric wheelchair, I was a little excited.

Lu Cheng demonstrated how to use it to Reba’s godmother.

I’m going to talk about it again.

Reba’s godmother said yes and couldn’t wait to sit up.

Lu Cheng and Reba helped their godmother into an electric wheelchair.

Reba’s godmother immediately began to manipulate.

Lu Cheng and Reba followed next to prevent accidents.

Reba’s godmother quickly became skillful in manipulating, circling the yard and going out to the outside.

“Oops! This electric wheelchair is too flexible to control, too easy to use, with it, I don’t need to be pushed in the future, I can also come out of the yard, around the neighborhood! Xiao Lu, thank you, Auntie likes it! Reba’s godmother said happily.

“Brother Cheng, thank you, seeing my mother so happy, I want to cry again, don’t laugh at me!” Reba said, her eyes reddened, leaving tears of joy.

“How so! I understand you! Lu Cheng wiped his tears and began to coax.

After a while, Reba laughed.

The godmother showed a gratifying smile, “Seeing Xiaodi happy and happy, it is also worthy of her dead parents!” ”
