Travel through the Three Kingdoms

Chapter 194 New Problems That Keep Emerging
Steam engine, this, Yang Yu really didn't think about it, you know, now, not to mention how difficult the technology is, even now, Youzhou has enough horses to pull the cart, so Yang Yu is not in a hurry to study anything Steam engine, isn't it necessary, but, indeed, this thing is really tough.

Not to mention how difficult the material is, just talking about some sealing rings and other things is enough for Yang Yu to consider, not to mention the problem of processing, you must know that until now, there has been no screw thread in Youzhou.

But, just when Yang Yu didn't want to, he was forced to think.

"My lord, it's not good, those coal mines, those coal mines..."

"What's wrong with the coal mines? Come on, tell me slowly." "Coal mines, the coal mines can no longer be mined, and several coal mines have begun to seep, and the ability to drain water is too weak. Basically, those few coal mines with water seepage, Can’t even work.”

This is a problem. In itself, the development of this coal mine did not come from open-pit coal mines, but directly from digging wells to dig coal. Although Yang Yu made a lot of safety regulations, there is really no such thing as water seepage. There is a way, if there is no machine for a large amount of drainage, maybe, maybe Yang Yu's dream about industrial progress will be shattered.

"Okay, I see, you go down first, let them explore other mines nearby, I will find a way." Yang Yu drove away the person who came to report the letter with a blank expression.

This, he had no choice but to deal with it with a deadpan face. If Yang Yu was also anxious, he didn't know how things would develop.

Regarding pumping a large amount of water, Yang Yu has a lot of ideas, but, thinking about it, thinking about it, it is inseparable from some mechanical knowledge. Yes, at this time, Yang Yu can manufacture some new types of water pumps for later generations, but the power is used. Animal power was used as the power, but Yang Yu canceled the idea before he could think it through. Why, the design required by these water pumps was too precise and could not be manufactured now.

In the end, Yang Yu still focused on the steam engine.

If you want to manufacture a steam engine, you must have simple manufacturing machinery, such as simple lathes, drilling machines and the like. Where does the power of these machines come from?
When he thought of this, Yang Yu realized that he hadn't implemented some ancient inventions. First of all, farming, because at this time, the water source in Youzhou is still abundant, and it is also very convenient for watering the fields, because Due to the population, there are almost no highland fields, so Youzhou did not worry about water conservancy, so the waterwheel was not invented.

"Okay, since you didn't use the waterwheel, then, let's make up this class." Yang Yu decided that he would start with the waterwheel. You know, the waterwheel is a good source of power, although the power It's a little smaller, but are you not in a hurry on the coal mine?

This is really not very urgent. Although there are many coal mines with water seepage, there are very few coal mines developed now, and other coal mines can continue to be opened around. The drainage is not too urgent.

Some people may ask, since there is no need for water conservancy, why don’t things like grinding noodles be needed? Doesn’t this also require power?

Well, everyone has horses, cattle and other animals, which are enough for milling. Who needs wind and water power to run a mill, especially when the whole people don't need it.

Yang Yu really didn't know that this affluence is also an aspect that affects progress!

A few days later, a large waterwheel was erected on a relatively large river. It was said to be a waterwheel. In fact, this waterwheel did not carry water, but was only used as power.

For this waterwheel, Yang Yu put some wooden planks where the bamboo tubes should be placed, and the force-bearing area is larger, so that the power will also be increased. Then, the waterwheel shaft is an extended shaft. At the extension end, Yang Yu built a house alone, and this house is the power house.

"My lord, this is the power house you mentioned. This, just such a spinning stick, can be stronger than the power of a horse." Some people questioned it, and that was normal.

"Hey, now, this thing is not very complete, let me make it complete, you can take a look again."

What to make?Naturally, it is a simple jig. Yang Yu wants to use this power room as a lathe room. Perhaps, at this time, what he needs most is a lathe. Tighten the fixture.

However, Yang Yu has a way. Temporarily, first make a binding fixture, and then place a center point on the extension of the shaft. In this way, a set of the simplest turning tools is completed.

If the speed is too fast, wouldn't it go through several stages of conversion to reduce the speed? Anyway, enough cement is enough, and some fixes can be fixed with cement.

At high-speed places, Yang Yu quickly manufactured some hardwood pulleys, even the center holes were punched to a very standard, so that some elementary speed reduction pulleys were available, and the belts were not easy to handle, so they could be directly connected to the pulleys. Cowhide, perhaps, will be used for a short time, but it is a belt after all, isn't it?

After several stages of transmission and multiple fixings, a simple wheeled house is built. Why is it called a wheeled house instead of a lathe house? In the whole room, there is nothing but pulleys and belts, no It's called a wheel house, what is it called, and the real turning place is in a small place, and the speed of cutting will be very slow.

First of all, Yang Yu asked people to prepare a lot of brass blocks. These are used to make threads and nuts. Why use brass.

Well, pig iron is too hard, and bronze is too soft. Only brass is used. Although the cost is relatively high, at the beginning, even if the cost is higher, some things must be developed as soon as possible.

When the wooden wheels are replaced with copper wheels, or even bolts are used, it will be much more convenient to make things.

"No, the pitch of this thread is too large, and this one is too small." After many experiments, Yang Yu didn't know how much hardwood and cowhide he had used. Finally, he finally produced a qualified thread. coming.

In fact, these are very simple, it's just a matter of transmission ratio. Unfortunately, Yang Yu doesn't know how to calculate the formulas in this area, so there is only one time, one time to rework.
