"Well, get up, what's going on with what I want you to make?" Zhu Qizhen walked towards the building house by himself.

Unexpectedly, after Ruan Lang got up, he stopped in front of Zhu Qizhen: "Your Majesty, it's dangerous in the house!" Please wait in the main hall! ”

Zhu Qizhen glanced at Ruan Lang in surprise, and there was disbelief in his eyes.

"Bang!"

At that moment, a loud noise came from the construction room, bringing with it the sound of billowing water vapor and clanging metal smashing.

Zhu Qizhen was taken aback, and quickly ducked to the side, looking at the billowing white smoke coming out of the construction room, and asked with some uncertainty: "This is what I asked you to make?" ”

Ruan Lang nodded affirmatively, "Your Majesty, the power of this thing doesn't need to be small with explosives, the slave maid has been tried and tested repeatedly these days, and it must have been a success." ”

Zhu Qizhen glanced at Ruan Lang suspiciously, "Is there only one steam engine being experimented?" ”

Seeing Ruan Lang nodding, Zhu Qizhen didn't ask him again, and walked towards the construction room by himself.

Speaking of making steam engines, Zhu Qizhen also has to thank Geng Ying, when he went out, he thought about building a steam engine train to shorten the time to go out, but he didn't expect to forget it.

Later, when I saw Geng Ying, I remembered the time when he was stolen, if he hadn't had this idea again, I don't know when it would have been.

It also happened that I was preparing to go to the West, and if I really made a steam engine before, it would be a big help.

"The emperor is dangerous, your majesty!" Ruan Lang shouted and hurriedly followed Zhu Qizhen, "Your Majesty, you still wait outside, if there is anything you want to see, the slave maid will let someone take it out for you!" ”

Zhu Qizhen ignored him, how could a steam engine still explode?

Either their process is not good and they can't let the inside of the machine run with steam, or the material is not good and can't reach a certain strength.

Just like the current cannons, the purpose of increasing the caliber can only be achieved by increasing the pipe wall.

Although this is also the case in later generations, the proportion of the two will be too different, and a cannon will be much more powerful than the current cannon of thousands of catties or tens of thousands of catties.

At this time, the gap between the industrial base and the steam engine, if the same is true for the steam engine, then Zhu Qizhen has nothing to do.

It's just that I shouldn't think about it, the gap in science and technology at this time should not be so big as the West in the seventeenth century, so that it can't even make a simplified version of the steam engine, right?

As soon as he entered the door, Zhu Qizhen looked at the debris all over the ground and knew that Ruan Lang had worked hard these days.

"What the hell is going on?" Zhu Qizhen thought in pieces, and began to pick up the fragments on the ground, mixed with the fragments of firewood that had not yet been fully burned.

Ruan Lang followed aside, constantly nagging in Zhu Qizhen's ear: "Your Majesty, it's dangerous here, you better go outside!" The slave and maid move everything out! ”

Zhu Qizhen ignored him, and after rummaging on the ground, he set his eyes on the cauldron next to him.

"That's what you use to boil water?" Zhu Qizhen asked.

Ruan Lang nodded again and again, "Emperor Shengming, this is the use of this pot, you see, this pot originally cast a lid on it, hey, little gold, bring that copper sheet." ”

After receiving a huge copper piece, Ruan Lang buckled it on the cauldron, and it was really tight.

Ruan Lang pointed to a small hole in the middle, "This place originally cast a copper pipe of the kind you said, which was used to transmit water vapor to steam, steam ......."

"Cylinder!"

"Yes, Emperor Xie reminds you, it's the cylinder!

When you get to the cylinder, push the piston again! movement on the piston.

Then you can push the wheels to turn so you can let the wheels run on their own! Ruan Lang tried hard to recall Zhu Qizhen's confession, and finally stumbled to complete the retelling.

Zhu Qizhen didn't notice anything wrong for a while, but just followed Ruan Lang's words and began to pull up on the ground, still chanting words in his mouth.

"The steam enters the cylinder through the pipes and pushes the piston to do the work...... Push the piston to do the work! Zhu Qizhen seemed to have caught something, but unfortunately the inspiration was fleeting, and he hurriedly shouted: "What about the cylinder!" ”

Ruan Lang hurriedly took the cylinder handed by his subordinates, and the heavy brass bent his thin waist.

Zhu Qizhen quickly looked at the cylinder handed over by Ruan Lang, the cylinder at this time had been torn open by the steam, and the piston and connecting rod in the middle were deformed by the huge pressure.

"Is it because the process is backward and the copper is soft, so it will be deformed as soon as there is pressure, causing the entire cylinder to be blocked, so the explosion will happen?" Zhu Qizhen's eyebrows were twisted into a Sichuan character.

Ruan Lang didn't dare to stand aside, listening to Zhu Qizhen's mouth full of unfamiliar terms, and secretly sighed at the emperor's profound knowledge.

Zhu Qizhen didn't have time to care about Ruan Lang's thoughts, his original experience as a scumbag could only help him get here.

He didn't dabble in more professional knowledge, and he couldn't think of what was wrong for a while, but he felt as if something was missing.

"What's missing?" Zhu Qizhen muttered to himself, the cylinder in his hand was unconsciously put together by him, and the connecting rod and piston formed a close and perfect closure.

He saw that there was an error, and it was entirely due to the deformation of the metal itself, not because of the manufacturing process.

"Three-cylinder, four-cylinder engines? Three-cylinder, four-cylinder, yes, three-cylinder, four-cylinder! Haha, there it is! Zhu Qizhen screamed, bounced off the ground suddenly, and then pounded hard at the piston connecting rod.

Then he slapped the door of his head and said quickly: "In a steam boiler, water boils into steam through the combustion process.

The steam is sent to the cylinder through the pipe, and the valve controls the time when the steam reaches the cylinder.

It enters the slide valve chamber through the main steam valve and throttle valve, and is controlled by the slide valve to alternately enter the left or right side of the cylinder to push the piston to move.

The steam pushes the piston inside the cylinder to do work, and the cooled steam is introduced into the condenser through the pipe to re-condense into water. This process is repeated constantly while the steam engine is in motion. ”

Ruan Lang came up and asked worriedly, "Your Majesty, is it the slave who made a mistake?" ”

(This chapter is not finished, please turn the page)

Zhu Qizhen had just solved the doubts of the explosion in his heart at this time, and explained excitedly: "I only said that you should make a pushing device, but I forgot that you also need a circulation device, you can come and see!" ”

Zhu Qizhen picked up the cylinder, it was a cylinder with only two ports, one port intake, and the other port pushed the piston, and the problem appeared here.

The gas went in and pushed the piston up, and then the gas kept coming forward, and the piston was more and more dead.

Originally, it would be good if the steam pressure had a place to vent, but in order to ensure that the steam did not leak out, Ruan Lang and the others deliberately cast this boiler in one piece.

This led to the fact that the cylinder could not withstand the increasing pressure after operation and exploded.

"You just have to put a valve here so that when the steam comes in, the piston movement will come back automatically.

No! No, no! It should be as said, this cylinder should be done on the left and right.

They implicate each other, one advancing and the other retreating, so that the function can be maximized! Yes, exactly! Zhu Qizhen pulled Ruan Lang and said excitedly.

"Do you understand?" Zhu Qizhen looked at Ruan Lang excitedly, and then the excitement on his face disappeared little by little......

"You don't understand, do you?" Zhu Qizhen asked knowingly, and then saw Ruan Lang kneeling on the ground with a frightened face.

"The slave and the maid should be damned, the slave maid has an elm head, and the slave maid is a pig!"

"Okay, okay, this thing is really too difficult for you, so I'll talk about it again......"

After coming out of the imperial prison, Zhu Qizhen did not return to the Qianqing Palace, but came to Shufangzhai.

At this time, Yang Caiwei has gradually adapted to the life in the palace, and is eating under the service of the palace maid, and she already has the royal prestige in every move, and she is getting farther and farther away from the hairy girl.

"Your Majesty!" Yang Caiwei saw Zhu Qizhen coming, and hurriedly got up and saluted.

"Okay, okay, sit down, bring me a pair of chopsticks, come in and spend the night with you." Zhu Qizhen laughed.

Yang Caiwei's face couldn't help but blush when she heard this, and her originally somewhat green face had a hint of mature charm after this flush appeared, and Zhu Qizhen's heart beat fiercely.

"The concubine will serve you dinner!" Yang Caiwei said that she had already taken the tableware in the palace maid's hand.

Zhu Qizhen looked at Yang Caiwei with a straight smile, holding the beauty's little hand with a pair of hands dishonestly, the newlywed Yan'er should be like this.

"Your Majesty, Yu Shoufu is here with the principal Yu Jian!" At this moment, Jin Qi hurriedly walked into Shufangzhai, snorting and panting.

Zhu Qizhen stopped his movements and hurriedly asked, "When?" Could it be that Yu Hai found it? ”

Seeing Jin Qi nodding in confirmation, Zhu Qizhen stood up and walked out, turned back as soon as he walked to the door, and pecked Yang Caiwei lightly on the face.

"Caiwei, you eat first, and I'll go back when I go."

"Hmm!" Yang Caiwei got up and sent Zhu Qizhen to the gate of the palace, looking at the disappearing back with no smile on her face, and finally only a sigh echoed in the empty Forbidden City.
