Chapter 123 – “About The Things I Did To Build A Generator In Song Dynasty

Chapter 123 “Things About My Generator in Dasong” (big chapter!)

Little known.

In ancient China, the purification of salt has always been a hassle.

In the most primitive tribal era, humans even obtained salt by drinking blood from their hair.

After entering the history of civilization.

The ancestors found the salt well, and only then did they obtain the processing method of coarse salt.

During the Tang and Song dynasties, refined salt refined from sea salt gradually appeared, and the price was high.

The highest price even reached one catty, or sixteen taels and ninety cents.

But the word refined salt here is actually a concept derived from the earlier coarse salt. . .

Compared with the standard table salt of later generations, the refined salt at this time still contains a lot of impurities.

Such as sulfate ion, magnesium ion, calcium ion, etc.

Especially magnesium ions.

After this stuff enters the human body, it will cause diarrhea, cardiac dysfunction and other abnormalities.

For Wang Yue at this time, this is simply a deadly substance, and injection is basically equal to murder.

In order to protect Wang Yue’s life, Xu Yun could only deal with it with refined salt for the time being.

After all, efficiency is the priority.

Besides, the purpose of adding salt is only to dehydrate the ethanol and increase the alcohol concentration, and there will not be too much residue entering the human body.

But right now we need saline injection, and it is foreseeable that this will be an extremely long-term treatment.

In this way, this part of the impurities looks a bit annoying.

Therefore, the purification of sodium chloride has become a necessary and urgent link.

True.

There are many ways to purify sodium chloride.

For example, shells, coconut shells, and any kind of acidic fruit can be used.

But don’t forget.

Xu Yun came to this era with a mission to complete.

The stronger the ability he displayed at this time, the easier it is to gain Lao Su’s trust.

Combined with the background factors of the times, he also needs a certain status to do something-whether he can succeed in the end is one thing, and whether he has the right to speak to do something is another.

Therefore, after careful consideration, he chose to rub a generator by hand and use electrolysis to prepare sodium chloride.

After making up my mind.

Xu Yun pondered for a moment, and said to Old Su:

“My lord, an IV requires a thing called normal saline, which needs to be made in another way.

So can you bother the master to prepare some things for the villain? “

“What do you need?”

“.These things can be a little expensive.”

Old Su flicked his sleeves when he heard the words:

“Zhengru’s life is important, the old man’s family is rich, you just say it doesn’t matter.”

Xu Yun nodded at this moment, and turned over the previous piece of paper with the ghost drawing talisman.

wrote the required supplies on it:

“A piece of natural magnet, it’s best to make it into this shape.

Then process the refined copper into a thin wire shape, the longer the better. Add two copper blocks and several copper sheets.

An iron shaft of half a meter, wooden mold, tung oil, turntable, graphite, witherite, and utensils for water supply in Fuchu are also needed

Then send someone to the sour plum shop in the east of the city to ask the shopkeeper if they have any white things that can make ice, and if so, buy some back

By the way, the donkey pulling the mill is also ready. “

After describing the requirements, Xu Yun handed the paper to Lao Su.

This time he is going to build a standard disc generator, the principle is Faraday’s electromagnetic induction phenomenon.

That is, magnetism generates electricity.

Among them, the iron shaft is made into the rotor core, the copper wire soaked in tung oil is wound on it as the winding, and the magnet is used as the stator.

belongs to the operation that can be done with hands.

What?

You ask about voltage?

U=kB∠nV, the voltage is equal to the coefficient multiplied by the magnetic strength multiplied by the effective length of the rotor multiplied by the number of coil turns multiplied by the constant speed difference, which can be calculated in advance.

At the same time, the accuracy of the required copper wire is only five millimeters, which can be easily achieved even by ancient industrial standards.

Looking at the whole process, the biggest problem is not technology and craftsmanship, but production cost.

According to Xu Yun’s design.

The cost of the entire generator is guaranteed to be more than 200 copper coins, which is two hundred taels of silver, and it may rise at any time.

Based on the concept mentioned earlier, it is almost equal to 200,000 in later generations.

And without a voltage stabilizer and a distributor, the things that this generator could do in ancient times were extremely limited.

To put it bluntly, this thing is basically the same as burning money.

So if you travel to an ordinary family, you probably haven’t worked out the generator yet, you will have to be hanged up by your parents first.

But in order to save Wang Yue right now, Lao Su obviously won’t be too fussy.

After getting Xu Yun’s blueprint, he immediately recruited Mr. Xie to take care of it.

Let the big housekeeper add night shift.

Xu Yun rubbed his sore neck, said goodbye to Lao Su, and went back to his hut to sleep.

A lot of things happened today, both in terms of energy and physical strength.

In addition, there is no Tifa in this era, so naturally I can only sleep obediently.

Nothing to say all night.

Early the next morning.

In Xu Yun’s ears suddenly came a vague voice:

“My lord, my lord, it’s time to get up in the morning.”

Xu Yun hiccuped and rubbed his sleepy eyes.

After regaining consciousness, I suddenly felt something was wrong:

In the past few days, although some people told him to wake up in the morning, most of them were rude.

Either hammering the door or shouting, how can it be as gentle as today?

Then he put on his clothes and opened the door.

I saw this moment.

Yong Zhu was standing outside the door with a somewhat restrained smile, holding water in both hands, and he did not see the casualness of saying ‘Wang Mazi’ yesterday:

“Prince Wang, you are awake, please use water.”

Xu Yun gave him a strange look and asked:

“Brother Yong Zhu, what are you”

“Don’t, don’t, you’re going to be a villain, just call me a pillar.”

Hearing the three words Brother Yong Zhu, Yong Zhu was shocked immediately, and said quickly:

“My lord, you don’t know something.

Master issued an order yesterday to remove you from your slave status and include you in the roster of the servants of the mansion.

Now you are considered a doorman, and you are different from our servants. You can call me whenever you need anything. “

“Doors?”

Xu Yun was taken aback when he heard the words, and then he understood.

Menke.

Also known as diners, it is a unique group in ancient times.

Most of them are rangers or counselors, without official positions, and some are even fugitives.

On weekdays, the lord provides the necessities of life, and will also contribute to the lord when necessary.

At the beginning, Lord Mengchang claimed to have three thousand diners, and there were also a large number of diners staying at Chai Jin’s manor in “Water Margin”.

In terms of nature, the door-keepers belong to the “guest”, which is much higher than the “servant”.

For example, Zheng Kuan, the leader of the nursing home, one of the four giants in Lao Su’s mansion, is a kind of ‘Bin’.

Therefore, the salary and status are much higher than that of the most senior “I” servant.

It’s just that they are inferior to Xie Lao Duguan, Yue Lian and others in terms of intimacy with the master’s family, so each has its own advantages and disadvantages.

If Xu Yun remembers correctly.

Lao Su also recruited dozens of retainers before he became an official. According to the records in the literature, some links of the Water Transport Observatory were completed by the retainers.

But now that Lao Su has retired, the number of diners staying in the house is estimated to be not many.

The empty east wing can also prove this point—there is the guest room, and theoretically all the guests should be placed in that position.

So in addition to the necessary position of the nursing home, there may be one or two retainers who have not been dismissed in terms of accounting.

In short, there is a high probability that the number will not exceed three.

The existence of true and rare.

be honest.

It doesn’t matter whether it’s a guest or a servant.

Born in later generations, Xu Yun actually doesn’t have high requirements for his status, so naturally he doesn’t order others around.

I saw him let Yong Zhu carry water into the house first, took the towel and washed his face, and then said to Yong Zhu:

“Brother Yong Zhu, don’t worry, Brother Yong Zhu, listen to me first.

Back then you were the one who rescued me from the well with a rope, so let’s not be abusive, there’s no need to be too pretentious.

How about this, if you think highly of me, I’ll still call you Brother Yongzhu.

As for me. Just call me Brother Wang, just like Brother San. What do you think? “

The “brother” in the Song Dynasty did not refer to the elder brother.

Still take “Water Margin” as an example:

In the episode where Wu Song angrily kills Pan Jinlian, the little boy who sells pears in Yanggu County is called Brother Yun, and he can be regarded as a small character with some roles.

Seeing that Xu Yun’s words don’t look like a lie, and at the same time, the reply at the sour plum shop yesterday also made Yong Zhu feel that he and Xu Yun have somewhat of a friendship.

So he hesitated for a moment, and finally said tentatively:

“Then I will call you Brother Wang from now on?”

Xu Yun smiled heartily:

“to make!”

After washing up, he went to the breakfast shed for a simple breakfast.

Then he went to the East Wing, and met Lao Su, Wang Zhi and Wang Yue.

as predicted.

Another round of nonsense, he finally persuaded Lao Su and Wang Tin to change his address from ‘Prince Wang’ to ‘Xiao Wang’.

As for Xu Yun’s title to Lao Su is still the master, after all, the disciples are also regarded as subordinates.

Then Lao Su told Xu Yun,

Last night, he saw that Wang Yue had a low-grade fever, and Xu Yun mentioned that allicin was difficult to store, so he gave Wang Yue a medicine with the remaining allicin.

While stabilizing the condition, it also means that the first batch of allicin has run out.

So Xu Yun’s goal today is very clear:

Completed the mass production preparation of the second batch of allicin and allicin injection!

Later Su took Xu Yun to another courtyard in the East Wing, where a pile of supplies Xu Yun needed was placed on the open space in the courtyard.

Um.

And that donkey.

After entering the courtyard.

Old Su pointed to these objects and introduced aloud:

“Xiao Wang, this is a natural magnet, an iron shaft, and a wooden model.

The copper wire was made overnight by the craftsmen of the Tool Making Bureau. You can see if it is suitable.

In addition, as you said.

There are indeed some white crystals that can be used to make ice in the sour plum soup shop, and I bought some back in the first year.

Oh, by the way, the water delivery device you mentioned is also ready, the pile on the left is there. “

Xu Yun nodded slightly, and first went outside the copper wire to check the accuracy specifications.

In ancient times, there was no insulating paint, so absolute wire insulation could not be achieved.

But under special circumstances, both leather paper and tung oil can achieve the substitute effect.

When Faraday first experimented, he also used parchment paper.

The theoretical upper limit of the homemade generator copper wire is five millimeters, which is also the width of half a fingernail. As a limit, the thinner the better.

The size of the coil of copper wire prepared by Lao Su is about two millimeters. According to what he said earlier, this is the result of the craftsman of the Tool Making Bureau that he found overnight.

That is to say.

In this era, regardless of the fine craftsmanship that takes a lot of time.

The processing accuracy of official industrial rapid mass production is about two millimeters.

Xu Yun secretly kept this information in his heart, then turned around and came to the side of the disassembled self-priming pump.

Sure enough.

As he expected earlier,

Although this self-priming pump is not as fine as later generations, it can still clearly see the operating principle of the suction pump, and

Balance spring and mainspring.

Xu Yun bent down, took the main joint of the self-priming pump in his hand and weighed it.

About fifteen to six catties.

Then he turned his head and asked Old Su with the self-priming pump:

“Master, I don’t know what this thing is?”

Old Su stroked his beard when he heard the words, a trace of pride appeared on his face, after all, this was his proud work:

“The name of this object is Sui Chung, and it was a small object that the old man accidentally discovered when he was ordered to build a water transportation observatory.

Just by accumulating power through wheel knots, the water can be sent tens of feet away, which is equivalent to the work of several servants traveling many times. “

Xu Yun was silent for a moment, then bowed his hands to Old Su:

“His skills are close to gods.”

His words did not imply any flattery, but a sincere admiration.

Although the principle of balance spring and self-priming pump is very simple in the eyes of later generations.

But in this era—or until the 17th century, this is a barrier to human cognition. (Note: This is not my obscenity. The Tianheng system created by Lao Su is the prototype of the mechanical watch of later generations. This is a recognized achievement at home and abroad in later generations. If there is a mechanical watch, there must be a balance spring. This achievement is attributed to Hooke The main reason is that the time is too long, and there is no physical evidence.)

This may be the wisdom of the Chinese ancestors.

After finishing his emotion, Xu Yun put his mind back to reality.

He first checked all the equipment one after another, and then officially started to assemble the generator.

Well known.

DC generator is mainly composed of stator and rotor.

The main components of the stator are machine base, main magnetic pole, commutation pole, end cover and brushes and other devices.

The main function is to generate a magnetic field.

The main components of the rotor are armature core, armature winding, commutator, shaft, bearing, fan, etc.

The main function is to generate induced electromotive force and electromagnetic torque, which is the core of DC motor energy conversion.

certainly.

If you want to time travel, just make a simple device, it doesn’t need to be so complicated.

The actual components include the main magnetic poles of the stator, the armature core, the armature winding, the commutator and the rotating shaft are basically enough.

The basic principle of DC generator is Faraday’s law of electromagnetic induction:

That is, if the conductor cuts the magnetic force line, an induced electromotive force will be generated in the conductor.

The teachers in the high school physics class should have demonstrated it, so I won’t repeat it here.

Normally.

This ancient generator needs to be cranked to generate electricity, a bit like using a pencil sharpener in elementary school, and the faster the better.

But don’t forget.

Right now, Xu Yun has a good thing, a clockwork:

It only needs to let the donkey first charge the mainspring, and then use a very simple torque to convert, the elastic potential energy of the mainspring can be converted into kinetic energy, and the motor can be operated.

As for whether the donkey is tired or not, this is not something Xu Yun considers.

Then Xu Yun wound the copper wire onto the copper sheet, and pressed the turntable below to fix the magnet on another shelf.

Then put the coil frame in the middle of the magnet, connect the wires end to end to form a closed loop, and the graphite acts as a carbon brush for conduction.

that’s it.

A simple generator will do the trick.

Yes, it’s that simple,

Actually, there are a lot of seemingly high-level knowledge in later generations. It is not difficult to restore in ancient times. There are two main difficulties:

One is its derivative application and storage. The difficulty of electrical appliances is much more difficult than that of simple generators.

The second is the process of recognizing this concept.

It’s like generating electricity.

Not to mention Xu Yun’s disc engine, when it is really extreme, you can generate electricity with two fruits.

Ubisoft’s server is not like this.

The ancients could not use electricity, not because their industrial level was not enough, but to a large extent because of their unfamiliarity with the microscopic field:

They don’t know the concept of electricity at all.

For example, Lao Su at the moment.

During Xu Yun’s assembly process, he was almost silent the whole time, because he couldn’t understand what Xu Yun was doing.

Xu Yun didn’t bother to explain. Some concepts are far easier to explain after seeing the phenomenon than teaching concepts.

After tinkering with the generator, Xu Yun was not in a hurry to start it.

Because he has another thing to do:

Prepare for electrolysis.

Grandma was in a critical situation yesterday. She stayed with her until four in the morning and woke up at ten at night, so there was no update yesterday.

This chapter will be added first, and there will be another chapter later, which is also a big chapter. It will be updated tonight! !
