Barbarian in Douluo

Chapter 54 054 Starting to Make a Steam Engine

Since then, my parents have been living quietly in Shenghun Village. My father still makes farm tools for the village, and my mother starts weaving. My life is simple and fulfilling.

Tang Sangang drew blueprints according to the appearance of a single plow in his memory, and handed it to his father to build it, which is convenient for the villagers to cultivate.Tang Hao saw that one of the villagers was pushing behind and the other was pulling in front. Although it was faster than using a hoe, it was still very slow.

He simply did it himself, connected several plows together in parallel, and then pulled it in front by himself, easily plowing a large area of ​​cultivated land under the shocked eyes of the villagers.

Tang Hao didn't explain anything. Now that his injuries are healed, he has to find something to do every day, otherwise he will get rusty. This is also good, men farm and women weave, and stay away from fighting, killing and intrigue.

I suddenly looked forward to the prosperous age that my son often described to him. Soul masters no longer fight each other, but promote social development. There are no longer distinctions between commoners and nobles. Everyone is born equal.

Rights should not be a tool for personal gain, but a responsibility that needs to be borne.It should be the power to seek a happy life for the people.

Such a prosperous world, I also want to see it...

"Dad~ Dad~"

The sound of Tang Sangang sounded, pulling Tang Hao's thoughts back to reality, glanced at his son in the distance, and said to the villagers with a smile: "My son called me, I'll go back first everyone~"

"Hahaha, go back quickly, maybe Xiaosan will bring something novel."

"That's right, even this iron plow was Xiao San's idea."

After greeting the villagers, Tang Hao came to the end of the field and asked with a smile, "What's the matter, son, what new invention?"

Tang Sangang pretended to be mysterious: "This is an invention that can change the world! I'm afraid Dad, a craftsman like you, can't make it~"

After Ah Yin's resurrection, Tang Hao was in a good mood, as if he was decades younger, and he talked more. He told Tang Sangang many things about himself, and the identity of this master craftsman was one of them.

"Hahaha, what can be difficult for your dad? Let's hear it!"

"Steam! Steam! Machine!"

Tang Sangang said word by word what he wanted to build. This is a great invention that can change the direction of the world. With it, manpower and animal power can be completely liberated.

Principle Every Chinese who has gone to school knows that the essence of human civilization is to repeat the process of boiling water~

After the water is boiled, the steam expands and is introduced into the sealed cylinder, pushing the piston inside to do work, and the connecting rod connected to the piston moves to do work.

Thermal energy is thereby converted into mechanical energy.

"Steam engine? What is that?"

"It's just a stove for boiling water..."

Tang Sangang returned home with his father with a smile, and handed him the blueprint. Each component on the blueprint was marked with a name, such as cylinder, piston, piston rod, air intake, exhaust port, combustion chamber, slider, etc. Valves, flywheels, centrifugal governors.

Tang Hao looked at it for a long time, and he could see that on the left was a boiler for boiling water, in the middle was a device that allowed steam to push a piston, and on the right was a flywheel, the ultimate purpose of which was to keep the flywheel spinning.

Looking at this blueprint, Tang Sangang was deeply moved. How many brain cells he spent to copy out the blueprint of the reciprocating steam engine, this is already the configuration of the steam train.

Thanks to Sims, Tang Sangang found related books in the library, and after studying for a long time, he drew the blueprints and asked his father to do them.

After the water is boiled, the high-pressure steam enters the slide valve chamber through the pipeline, and then enters the cylinder to push the piston to do work. When the piston drives the piston rod to drive the flywheel to rotate, the slide valve rod connected to the piston rod also moves accordingly, and the slide valve It will open and close the intake port and exhaust port on the cylinder by moving left and right, so as to achieve the purpose of reciprocating left and right to push the piston to do work.

The centrifugal governor is connected to the flywheel, and the purpose is to keep the flywheel at a stable speed. There are two iron balls on both sides of it, which are suspended on the round rod. When the speed of the flywheel is too fast, the round rod rotates accordingly. As it speeds up, the iron ball rises upward due to the centripetal force, driving the valve of the steam chamber to close, reducing the steam entering the cylinder, so the efficiency of the piston’s work is reduced, the speed of the flywheel is reduced, the centrifugal governor is also reduced, and the valve of the steam chamber is again Turn it on to keep the steam engine's motion efficiency in a stable state.

It took about 100 years for the whole device to be gradually perfected. The intake port, exhaust port and slide valve on the cylinder have been carefully designed by predecessors. If the proportions are wrong during production, it will be a failure.

Tang Sangang didn't expect his father to make it in three or two days. After all, the cylinder with a very smooth interior is a problem. There is no machine tool in Douluo Dalu, and all metal instruments are hammered out with one hammer. It is simply impossible to create a qualified sealed cylinder!

But this is a different world after all, maybe God of Craftsman will have a way?
Tang Sangang could only say: "Cheer up with the wind hammer method! The only criterion for judging the craftsmanship in the future is to build a steam engine purely by hand..."

Tang Hao turned over and looked at the drawings for a long time, but he didn't understand what this thing was used for, so he asked: "Son, is the ultimate purpose of what you want to make is to make a wheel spin? That's too much trouble, right? ..."

"No, no, it looks like a wheel on the surface, but it's actually a man-made steel soul beast with infinite strength!"

"Just imagine, if this machine is mounted on a huge carriage, it can move forward without being pulled by livestock. It is tireless, emotionless, and powerful. What a great impact it will have on social development. contribute!"

"On a small scale, it will shorten the distance between people. Even on both sides of the mainland, it only takes a few days to meet each other. On a large scale, it will completely change the society. Many people need manpower It can replace any place, just like installing an iron plow on a cart and driving it forward, then one person can completely plow the arable land of the village!"

"The battlefield will not be suitable for it, but the fields that transform people's livelihood are more suitable for it."

That's right, Tang Sangang has only two clear goals for the application of steam engines in the future, one is trains and the other is tractors.

Trains can promote trade exchanges across the continent, increase population mobility, and weaken the boundaries of kingdoms, principalities, and empires.

A tractor equipped with an iron plow can plow the land, which is even more impressive than Tang Hao, the title Douluo, who goes to the field himself, and the rotary tiller can also be modified later.A steam combine is a bit more difficult, but a threshing machine, husker, seeder, and steam mill are easy to implement.

This will strongly liberate agricultural productivity, allow more people to invest in other industries, and make outstanding contributions to social development.

"Father, now you know why I asked you to make a steam engine. This is just the beginning, just like a carriage with only one wheel, but the wheel of the steam engine will be as thick as the wheels of history."
