Boss Huang, you're here, we were waiting for you yesterday! It's so serious, Manager Xu, don't I just come, this is a passbook, the rest of the money is on it, tens of thousands of dollars are not easy to take now, it's more convenient to give you this, you can let people check it.

Boss Huang is worthy of seeing the world, and he can still have this kind of trading method. When you withdraw the money, remember to help me close my account, and I will have to open another account in the future. Okay, Boss Huang, I know that I will immediately ask people to go to the bank to make transactions, as long as our money arrives in our company, the key will be given with both hands. You are still chewing words with me, hurry up, I have to rush back to the factory for something. Boss Huang said with a smile, you sit down and have a sip of tea first, the bank is not far away.

I'm sorry to delay your time, Boss Huang, you will be our valued owner of Lishui New Town in the future, and you are welcome to go home often. Thank you Manager Xu for your thoughtful service, I have a friend who wants to buy a house, I will definitely introduce. Then thank you Boss Huang, Boss Huang walks slowly.

Director, you're here. Master Lin, I have found the manufacturing method of the DC motor, do you want to take a look? Really, I searched the library and couldn't find it, where did you find it, factory director? My uncle always buys shoes and magazines when he goes to Hong Kong on business, and this is one of them, which has a description of how to make a DC motor. In terms of power, it is 8 times stronger than the previous DC motor, you see.

It's so simple, it's really fake! You dismantle this small motor, find some copper wire to re-wrap it, and then try to power it on. By the way, let me listen to the sound of this small motor first, and I'll compare it later.

Factory manager, I'm starting to power up, are you ready? Master Lin, do you want to find something to fix it, this magazine says to increase the power by 8 times, what do you say? Also, I'll clamp him, and you can try to power it up.

Buzz Buzz!

Oh, the speed is obviously fast, the sound is different, this is it, it's too simple! Haven't you heard of Master Lin's obstacle? What kind of high-tech can the city library have, and I will have to look for foreign magazines when I have the opportunity in the future. Germany, Britain, and Japan have to admit that their science and technology are stronger than ours, and our country is still too backward.

Turn it off, factory director, you have a point, I used to be a frog at the bottom of the well, can you take this magazine back to me? Yes, but the production method of this DC motor is torn for me, even your family can't let them know. At least after our factory produces new products, otherwise I will not be busy in vain. That's no problem, I know the importance of this book. I didn't expect such a simple thing, and I thought about it for several years without progress, and I feel ashamed to think about it.

It can't be said that Tesla only developed the DC motor in 1891, and a hundred years later, that is, last year, the surname Fu discovered the mystery and made changes to create the world's first DC motor. Europeans and Americans have spent more than 100 years, but their scientists are great, such important knowledge is not hidden, but also taken out to share with the world, very great!

Yes, these people are very great people who have made great contributions to the progress of human society, and their names will be remembered forever.

So Master Lin, can our factory officially produce DC motors? The factory director hasn't told me what exactly you want to produce, and whether there are any drawings. That's it, I went back last night and drew it well. These two circles are naturally the exhaust fans driven by the DC motor, and the exhaust fan in your kitchen is the same meaning, the only difference is that your home is a motor and I use a motor for this product.

Below this is an oil storage tank, the smoke can be completely discharged but the oil cannot, the oil that cannot be discharged will slowly flow to this oil storage tank, as long as it is cleaned regularly, this oil storage tank can be disassembled, you know what I mean?

What about the round hole on the top, which is used for smoke exhaust, and the upper part? The upper part needs to determine the length of the pipe when it is installed, and the top is a hose, you have to go to the tin foil factory to ask if you can produce heat-resistant tin foil pipes, if you can't do it, I can teach them for free, and if it doesn't work, use copper pipes instead.

I still don't know much about what a tin foil tube is. If you look at this picture again, you can understand that the tin foil tube is spiral-shaped, and inside is a steel wire, like a spring, but it should be made very thin and easy to fold. When our range hood was manufactured and put on the market, we had to drill a hole in the wall and put the tin foil hose on the smoke outlet hole above the range hood. Because the tin foil hose can be folded, the other end is connected to a 50 cm long iron pipe, and the iron pipe is placed in the hole, the problem of smoke and oil pollution is completely solved!

Factory director, you are really a genius, you can imagine this, I heard that you are a tannery and a garment factory, how can you think of this range hood!

On a whim, I just bought a new house, considering the problem of kitchen fumes, I have a big head, and I also thought of it by chance, you get this DC motor out first, and I am asking Section Chief Feng in the factory to purchase the materials that need to be used.

Okay, factory director, I'm going to experiment, I understand the principle, it's easy to make, if I still can't get it, it's really in vain, factory director, don't worry, I'll give you an answer as soon as possible. If you still need someone to help, arrange it yourself, and I know a few people in the factory. I know the director, you just wait.

Section Chief Feng look at this, what materials do you think are needed? Factory director, you suddenly show me a drawing, how can I know what materials are needed for this, I have never seen this thing. That's right, I haven't seen it. This is a new product from our factory, you have to buy some aluminum flakes and send them back to Master Lin, he is anxious to use it.

Is it just an aluminum sheet, the factory director, such a strange thing is just an aluminum sheet? Yes, when the time comes, it will be pressed into the shape we need by machine and then welded. Don't think it's complicated, when you understand the principle, you will know how simple it is, now that the big problems have been solved, just wait for you to purchase back the aluminum sheet for trial production, go ahead. Okay, factory director, I'll go right away!

This factory director has a problem with his brain, saying that there are a bunch of things that he doesn't have, how do he feel that he is not reliable at all!

By the way, Section Chief Feng, do we have a master who can spray paint in our factory? Oh, the master of painting is not in our factory, the director, does this product still need to be painted? Yes, communicate with each other among your section chiefs, recruit two, and use them in the future. Recruit the elderly, don't be under 50 years old. Why? I'm afraid that he won't be honest and go out to talk nonsense, and the master will be stricter and know the severity.
