Become a feudal king from today

"Your Highness, the steam engine exploded..."

Scratching his head, Wang Chong blushed a little. read

During this period, King Yan and the soldiers of Yanzhou fought bloody battles and once again thwarted Beidi's plan to move south.

He has not been idle either, he has been busy with the task assigned to him by King Yan before the war, to develop a compound steam engine.

According to King Yan's drawings, he asked his father to free up five hydraulic boring machines for him and cast five solid steel columns with a diameter of one and a half meters and a length of one meter.

It took a month for the hydraulic boring machine to finish cutting the five steel columns into a structure similar to a wooden barrel.

Immediately, he and the students personally polished the cylinder plugs and made connecting rods and other parts needed for the compound steam engine.

It also experienced air leakage, deformation, and other problems, and four steam engines were eliminated.

Finally a complete compound steam engine was built.

At this time, the war in Yanzhou also came to an end.

Originally, he wanted to test it several times.

If the steam engine can run normally for more than half a day without malfunction, he will come to report the good news to King Yan.

But I didn't expect that there was something wrong with the slide valve stem, and the slide valve was not opened. As a result, the high-pressure steam in the cylinder was not discharged, and it inflated like a balloon and exploded.

Thinking of this, he told the story to King Yan.

"Hahaha..." Zhao Xu laughed. He had no intention of blaming Wang Chong and the others for this accident.

The biggest concern is whether anyone was hurt by the explosion.

If something breaks, just rebuild it, but if Wang Chong is gone, the loss will be huge.

Therefore, he said: "As long as you are fine, you should be careful in the future. As for failure, this is a common thing in technological exploration, so there is no need to feel guilty."

As he spoke, he walked into the physics laboratory.

Wang Chong and the others asked Gongcao officials to build a new laboratory for them.

It is a small one-story bungalow with a cement red brick structure.

After letting Wang Chong take the lead in physics, he gave Wang Chong some authority, including applying for money from the government and asking the government to provide them with conveniences.

At this time, the small bungalow was in a mess.

There was something like an iron bucket that had completely deformed and was lying on the ground.

The connecting rods, crankshaft, flywheel and other parts of the steam engine are also scattered everywhere.

"Have you figured out the reason for the failure of the slide valve stem?" Zhao Xu asked.

The Northern Expedition is over, and the war will only focus on Yanzhou along the long border.

And relying on Yanshan, Yanguan and the fleet, he was confident that he would not let a single Beidi soldier enter Yanzhou.

Therefore, even if Beidi intends to rely on its strong national power to engage in a war of attrition with him, it will not affect Yanzhou in the short term, but it will be troublesome in the long term.

The only way to solve this problem is to use the knowledge in your own mind to improve Yanzhou's technical level and productivity level.

There is no doubt that the steam engine is the answer to all problems.

It is also the key for Yanzhou to move towards the first industrial revolution.

Why?

The height of development of human civilization is closely related to motivation.

From primitive society to modern society, it has experienced four stages: manpower, hydraulic power, steam power, and electrical power.

Each stage of improvement will significantly improve technological levels and productivity.

One person operating a machine can even do more work than hundreds or thousands of people in a day.

It is foreseeable that as long as the steam engine is put into use in Yanzhou, it will greatly alleviate the problem of Yanzhou's labor shortage.

Even if more young men are recruited to join the army, it will not cause great damage to Yanzhou's production.

After all, with the steam engine, women's productivity will also be liberated.

Mechanical textiles with the advent of the steam engine were women's world.

"I found it. The connection between the slide valve rod and the flywheel was loose. Just when the student in charge of guarding was in a hurry to urinate, so..." Wang Chong turned his head and glared at the students behind him.

The student immediately shrugged his head.

"So, this compound steam engine is basically fine?"

"Yes, Your Highness, there are five steam engines. This is the only steam engine left." Wang Chong looked proud.

Zhao Xu nodded with satisfaction.

In his opinion, the main difficulty of the steam engine was to bore the cylinder.

As long as there is no problem with the sealing of the cylinder, most of the problems of the steam engine will be solved.

After all, a steam engine is equivalent to a modern kettle with a spout.

The main body of the kettle is equivalent to the cylinder, and the cover on the spout is equivalent to the slide valve.

When the spout is closed, the lid of the pot will be pushed up by the steam, which is equivalent to the cylinder plug of the steam engine being pushed out by the steam and moving outward.

At this time, loosen the spout to let the excess steam escape, and the lid will fall, which is equivalent to the cylinder plug moving inward.

From this, the reciprocating motion of the steam engine was born, which is also the origin of the name of the compound steam engine.

As for the functions of the connecting rod, crankshaft, and flywheel, they are actually to convert linear motion into wheeled motion.

The connecting rod is a stick-mounted iron piece with round holes at both ends.

A flywheel is a wheel equivalent to a wheel.

The crankshaft is the most important of the three things. It can convert the force from the connecting rod into torque to make the flywheel rotate.

It is a roughly N-shaped continuous short metal bar.

"Well, your next task is to get the steam engine out of the laboratory and teach the craftsmen how to produce it." Zhao Xu couldn't help but be a little excited.

Speaking of which, this battle has been going on for two or three months.

It is indeed good that Wang Chong was able to build a qualified steam engine during this period.

"Yes, Your Highness." Wang Gaoshang responded loudly.

The test results of steam engines during this period made him fully aware of the horror of steam engines.

Nowadays, the hydraulic drilling machines and hydraulic boring machines in military departments and workshops can replace ten or even a hundred with one.

If they were replaced with steam power, he couldn't imagine what the efficiency of the military division and workshops would be like.

The group of people were talking.

At this time, there was another messy sound, and then Wang Ying appeared nervously.

Seeing that Wang Chong was still fine, he breathed a sigh of relief.

Seeing King Yan also there, he immediately came over to salute.

"Wang Chong is fine, just keep your heart in mind." Zhao Xu said to Wang Ying.

Wang Ying said calmly, "I'm just here to take a look. If he is killed, we can collect his body."

"Dad, why don't you hope for my well-being at all?" Wang Chong's face turned green when he heard this.

Wang Ying said seriously: "What's wrong with this? Research and development work is like soldiers fighting on the battlefield. If something unexpected happens, they will be wrapped in horse leather like soldiers. There is no need to be pretentious."

Zhao Xu knew Wang Ying well and knew that he was not a man who beat around the bush.

When he said this, he meant it.

Both father and son are fulfilling their vows to themselves.

Thinking of this, he patted Wang Ying's shoulder, and then patted Wang Chong's shoulder.

Let Wang Chong go back to clean up the mess, and he and Wang Ying walked out alone.

"Wang Chong has done a good job. The steam engine has been developed. The war department and the workshop will benefit from the steam engine in the future. But before that, I have a very important thing for you. You and the craftsmen should explore it first." Zhao Xu said.

Once this happens, he will beat Beidi very hard.

Yanzhou will be more stable from now on, and it will be easier for the fleet to open up maritime trade.
