Yao Yuan stopped drinking, and Liu Jian couldn't force him, but he did have a lot of things to say to Yao Yuan in his heart.

He felt that he had found a soulmate.

In fact, as long as he needs it, Yao Yuan can become a confidant with anyone. This is the ability he trains to cultivate cadres, fully grasp other people's psychology and know what others need.

This ability requires experience and rich experience in life.

Meimei is still young and has insufficient experience, so she is still far behind in this regard.

This is also what Yao Yuan is worried about. Sometimes, he has to come forward in person to win people's hearts for Meimei.

Although Liu Jian wanted to say a lot to Yao Yuan and asked him many questions, Yao Yuan didn't want to continue talking, so he had to give up.

Finally, he asked Yao Yuan: "Brother Stupid, how can I improve my speaking skills?"

Being able to realize that his conversation level is insufficient, which shows that Liu Jian has taken great care in the process of talking about business and has seen his shortcomings.

Trying to improve knowing that you have shortcomings is called ambition. No matter what era the world is in, it is always rare for people with ambition. People like Liu Jian who are ambitious and smart are even more rare.

Unfortunately, Meimei still couldn't see this. She just fought with Liu Jian with her heart. Haste would be ineffective, which was completely different from using Liu Jian's original intention.

Yao Yuan felt that Liu Jian was available, so he patiently answered his question and said: "The accumulation of cultural knowledge determines a person's level of conversation and level. Read more and understand the world more."

Liu Jian nodded and said, "Silly Brother, you've talked about it again. When I was in school, I was in the most chaotic time and didn't study hard. I also felt that I had read less and didn't know a lot of things."

When Yao Yuan heard him say this, he nodded and said after a while: "People will learn from the environment they are in. If you are with Wang Qiang and the others all day long, your behavior will be close to them. It is best to talk less with them. Of course, if you don't interact, you will not be affected."

Liu Jian looked at Yao Yuan, nodded solemnly, and drank all the remaining wine in the cup.

The summer of this year was too hot, and Aunt Jiang and her children couldn't stand it and couldn't stay in the house. Yao Yuan rode a motorcycle around the city, hoping to find someone who sold electric fans.

As a result, just like buying an electric heater, he was disappointed again. It was the 1980s and there was no electric fan!

And these things, including the MSG chicken essence he wanted to use to cook, were sold in the store before the turmoil.

It doesn’t matter, I’m making it myself!

At that time, the factory also sold garbage. Some mechanical and electrical accessories that were not needed and were abandoned had accumulated too much space in the warehouse, so they notified the waste recycling station of the biomass company to purchase it in the factory.

The scrap recycling station is public, just like Sister Liu, a waiter in the hotel on the side of the mining machine road, and there is no good service attitude. The factory may not be willing to come after calling ten or eight times.

With the increase in surrounding rural enterprises, rural enterprises also need some accessories of one kind or another, but they cannot be bought in the market.

Some people fell in love with this loophole and took the initiative to go to the factory to purchase these unused mechanical and electrical accessories, classify them, and then sell them to township companies at a high price.

Over time, such a mechanical and electrical freight market has been formed in the suburbs, and everything from the largest machine tools to small parts as small as screws is sold.

Yao Yuan rode a motorcycle to the mechanical and electrical freight market. After a day, he ran back and forth several times and got a small three-phase motor, a large iron disc, a steel pipe, and two iron plates back.

Then, he asked Meimei to go to the factory to borrow two small electric welding machines, pistol drills and taps for him. He started his own home electric fan in his yard, in the heat of the heat.

When Meimei heard that he wanted to build an electric fan by herself, she also ran over to see it. When she saw the three-phase motor, she couldn't help but laugh.

The power supply of the motor is three-phase, and the electricity used in the home is two-phase. Even if you build an electric fan and don’t have a three-phase power supply at home, how do you use it?

Yao Yuan said how did you learn the mechanical and electrical knowledge in college? What is the three phase? Isn’t it just the alternating current of three sine waves? I added an alternating capacitor to the two phase electricity. Will a sine wave become three? Can the motor rotate?

Meimei was stunned, but in theory it was indeed the case.

She said, "Isn't this the deflection coil of a two-phase motor? How can you save trouble with a two-phase motor?"

Yao Yuan said: "Nonsense, why can I find two-phase guys who are two-phase guys who are three-phase guys? I'm full and full?"

Meimei said: "The resistance value of the three-phase motor coil is the same, and the resistance value of the deflection coil is the same as the power coil. Can it work?"

Yao Yuan shook his head and sighed, "You are still too stupid. How can you be a big leader if you continue like this? Why do you do different things if you don't care about him? I'll ask you, I'll add a deflection capacitor, can it turn?"

Meimei thought about it and said, "It should be possible to turn it up. But in that case, the coil load of one item will be larger than that of the other two items and will be easily burned."

Yao Yuan said: "What does my motor drive? The machine tool or the gearbox? I bring a fan wing. How much effort can it take? It will burn it? I think it's your brain that burned it!"

Meimei smiled: "Your brain is not human brain at all!"

Sure enough, when the large round iron plate is connected to the steel pipe, the base of the fan is formed. A piece of iron plate is welded flat on the steel pipe, drilled and tapped, and the motor is connected to the base.

Yao Yuan made a piece of iron plate that was a millimeter thick, and cut it with chisels and cut it out. Then he tapped and beat the leaves to turn into an inclined spiral shape, and finally welded to a circular tube with a keyway and sprayed with paint.

After the paint is dry, connect the fan wings to the motor and fix the end surface with screws. Once the power is sent, the fan wings will turn. Although it is not very balanced and the vibration is stronger, the wind is still not small.

There is wind, but the fan's wings have no isolation cover. What if someone gets close to them and is hit by the wings?

Yao Yuan has a way. When he opened a specialty store, didn’t he buy some thick screens and nail them to the wall to hang clothes? It’s coming in handy now.

He used several thick iron wires as skeletons, welded them together to form the fan cover, and then used a thick screen to make a cover, drilled holes and tapped the motor, fixed it to the motor with screws, and then tied the two thick screen covers together with copper wire, and the fan had a cover.

Now that Aunt Jiang is so happy, his stupid son-in-law is so talented! When he was having a meal, he would never sweat profusely.

There was a big fool in front of you. Aunt Jiang and Meimei were exposed and inconvenient when they were having food. They were almost as good as the punishment every day.

The key is that Aunt Jiang still has to feed Yuanyuan. If Yuanyuan doesn’t let the fight, she will bully her grandma. Don’t mention this.

Now it's good. Everyone doesn't have to eat like before. They can quickly break up and chat and smash their teeth.

But Yao Yuan forgot that this fan is not like the vertical fan sold in stores in the future, and can sway its head. The broken thing he made can only blow in one direction.

When eating, everyone sits close to each other and the fans can basically blow all the fans. But when you sit in the house, you can't sit in the same pile as you eat, right? Besides, you can't stand it if you always blow in front of the fans, especially at night, which is easy to freeze. Just like Aunt Jiang's age, you are also prone to rheumatism.

In addition, the fans sold can adjust the speed, but the thing Yao Yuan made does not have this function.

Don't think about speed regulation. The motor coil does not have multiple sets of different speeds, so it can't create a frequency converter for a broken fan.

There were no integrated blocks at that time. Not to mention integrated blocks, even transistors were not common. The inverters were all electronic tubes, and the volume could be enough to support a single-cylinder washing machine.

As for letting the electric fan swing the head, there is still a way to change the worm gear and worm gear, and add a crank rocker mechanism.

So he got a piece of paper and even the surveying and drawings were made, he had the drawing for Liu Jian.

He can find anyone to get these small accessories. It is mainly an excuse to ask Liu Jian to do it for him. He has to help Meimei settle Liu Jian.

Liu Jian was really serious about what Yao Yuan had entrusted. He went to find familiar workers with high technical skills and searched for materials in the workshop. In two days, he really brought them here.

Yao Yuan took off the cover behind the fan motor, removed the cooling fan, and then used a small tube with keys to connect the vortex rod and the motor shaft together.

At this time, Meimei interrupted again: "You removed the motor cooling fan, will the motor not burn?"

When she met Yao Yuan's look at her, Meimei shut up directly.

The big horse pulled the cart, and the motor couldn't get much heat at all. I was worried that it would burn, so it was just a matter of worrying about it. Yao Yuan didn't scold her for being stubborn.

The small iron box that Yao Yuan asked Liu Jian to make was equipped with a worm gear and worm system. Then connect the motor to the small shaft that Liu Jian car came from, and change it to the iron plate on the base to a bearing connection. The small iron box is also fixed to the motor, and add an iron plate to the turbine shaft in the lower section of the iron box to make a movable connection with the base. As soon as the motor rotates, the head swings back and forth.

The small shaft in the middle of the small turbine is hollow, with a small spring and a steel ball inside. The small shaft can have two positionings. One position is connected to the worm, and the motor will swing the head. One position is separated from the worm, and the motor will not move and blow directly.

This mechanism is actually the later vertical fan, and the later mechanism that controls the head swaying, but it is made of molded molding, which is low-cost.

Because it is plastic, it will be damaged soon. Those who are a little older may have this memory, and the fan will not shake their heads.

In fact, it is because the worm gear and worm mechanism behind is plastic, which is not resistant to wear and tear and is broken.

Yao Yuan's set was a real iron guy, and he was processed through a machine tool. If you buy such a set of institutions outside, the price would probably be less than that of buying a fan.

However, this thing is much stronger than plastic ones and will never break even after being used.

In the eyes of people who do not understand the principles of mechanical principles, this institution is still very complicated. In Yao Yuan, this thing is a pediatric department, and he can draw pictures at will.

Yao Yuan took such great effort to do it himself, process and welding himself, and then found someone to go to the factory to process accessories, and finally made a head-swinging electric fan.

However, he also had a problem with his brain and was directly inaccurate about the historical memory of this era.

Next spring, there will be electric fans in the mall to sell them. They are much more beautiful than the one he made himself, and the movement is much smaller, and they are still three speeds.

He worked hard to build a fan, and only used it for a summer, but it could not be considered the whole summer, and it turned out to be a waste.

Only Aunt Jiang feels sorry for him that it is not easy for him to build a fan. The key is this intention.

Aunt Jiang was reluctant to throw away the fan made by Yao Yuan, and forced everyone to use the buzzing self-made fan when they were eating.

However, when I went to bed at night, Aunt Jiang didn't dare to use it, so she switched to the hair dryer she bought.
