Chapter 683: King Weis suffering and dreams in the past three years
The family was having breakfast. The whole family in Lishan got up very early. To be precise, all the villagers in Lishan got up very early.
At this time, His Majesty is on vacation in Lishan Mountain for summer vacation. If there are important matters in the court, the Emperor will ask a question or two, and then hand them over to the supervision of the Crown Prince, and the Prime Minister and Duke Zhao will take charge.
The emperor's vacation life was basically like this. He rarely got up early in the morning. He usually waited until everyone had finished breakfast and the sun had risen three poles before going to the mountains to have a meal.
"Brother Emperor, hasn't the steam engine been built yet?" Li Zhi and Gao Yang were both curious.
"Well, if you encounter some problems, come see your brother-in-law." Li Tai took the bowl of porridge brought by his aunt and asked his guard to hand over a large piece of iron while eating.
This iron tool is cylindrical in shape, with large ends and a slender middle. If you look closely, it looks more like a barbell.
The aunt handed over a stack of cakes, "These are cakes made from this year's new wheat. Your Highness, King Wei, can eat more."
"Hmm, Auntie Xie." Li Tai said while eating something.
Zhang Yang took the barbell-like object and said, "This is what you use to make the air valve."
Li Tai nodded and took out another drawing, "This is the air valve in the inner cavity of the steam engine. I thought it was successful at first, but later I found that it always gets clogged."
Now we are just one step away from the completion of the steam engine. The overall framework is already in place, but the only problem is the details.
Some details are fatal. Once important details are not done well, the steam engine will not be able to complete it.
Zhang Yang looked at the air valve. This is a part placed in the cavity of the air valve. The steam pushes the barbell to move.
When air pressure enters one end, it will move to the other end, and vice versa.
In this way, the object can be moved left and right under the action of steam power, which is the key to the conversion of steam engine energy.
Zhang Yang walked into the workshop with the parts and drawings. While talking, Li Tai spread some bean paste and meat sauce on the cake and hurriedly followed and went to the workshop.
The sun has not yet reached this end of Lishan Mountain, and the workshop is still a little dim when it is opened.
When I opened the workshop door, some mist entered the workshop from outside.
The wind seemed cold when it blew by. Li Tai hesitated, "I didn't expect it to be so cold in the morning on the mountain."
Zhang Yang lit the oil lamp in the workshop, spread out the drawings, and frowned: "How did it get blocked?"
Li Tai laid out some objects and demonstrated, "When we opened the inner cavity, this thing was pushed aside and stopped moving. If it hadn't been turned off to cool down, it might have exploded again."
Judging from the drawings, the inner cavity of Li Tai's steam engine is rectangular.
Although the appearance of this steam engine is very different from that of later generations, and it is very large, like a house.
After all, it was Li Tai who made it from scratch, from theory to practice, and it took three busy years.
When Lishan was first opened, it took two years to make springs.
Because of the spring, Lishan got refined iron material.
After that, it took another year, and now we have the Li Tai steam engine.
In a total of five years, Lishan's initial industrial achievements were only these three, and the third steam engine has not been successful yet.
Zhang Yang also felt that he was heading in the right direction, and was also worried that the technology tree was crooked.
But results are results, and if they can be produced, they are not in vain.
Taking two iron plates from the cabinet, Zhang Yang demonstrated again, bringing the barbell-style air valve close to the iron plates, and then fitting them together tightly, "Is that so?"
Li Tai nodded, "That's what happened when the inner cavity was opened."
"Well, let me think about it." Zhang Yang sat down and looked at the fitting position between the air valve and the iron plate, and suddenly thought of something. Parts related to the bearing assembly all require the same process.
This process is called chamfering. The existence of chamfering can not only protect parts, but also increase the use time of specific objects and improve the use experience.
If there are no chamfers, these sharp edges and corners will make it fit against the iron plate, leaving no point for the internal air pressure to focus.
The chamfering angle needs to be larger. Zhang Yang picked up the air valve, placed it on his lathe, fixed it with a clamp, and tightened it with a wrench.
Li Tai asked curiously: "Brother-in-law, what are you doing?"
Zhang Yang frowned and said, "Cut it into a chamfer."
Although Lishan's casting process is good, there are still many technical bottlenecks in other specific processes, such as arc-shaped grinding, which requires the use of a lathe, unless you have the patience to grind such high-strength fine iron.
Zhang Yang took off the flywheel on the lathe, replaced it with the air valve made of fine iron where the flywheel was originally installed, and fixed the ends with rivets.
Then he clamped the other end with an iron pestle and stepped on the pedal under the lathe. The belt drove the bearing to rotate, and the originally fixed air valve also began to rotate. Then he used a wooden board to block one side of the blade. Li Tai came closer and looked at it curiously.
, Zhang Yang said quickly: "His Royal Highness, King Wei, stand farther away."
Hearing this, Li Tai took a step back.
Feeling that it is getting harder and harder to step on the pedal, the belt drives the wheel to rotate, and the speed increases until it reaches a certain speed.
"Please, Your Highness King Wei, please bring the kettle."
Li Tai nodded when he heard the words, but saw his father also walking in.
Zhang Yang grabbed the handle on the side of the lathe and pushed it. When the blade came close to the corner of the rotating "barbell", sparks appeared and there was a harsh sound.
"Pour water on the knife."
Hearing the words, Li Tai quickly poured down the water in the kettle. As the cutting continued, the water in the kettle poured on the knife.
Li Shimin has been standing at the back, carefully observing the lathe.
After only half a stick of incense, the blade broke. Fortunately, the lathe was equipped with a baffle, and the broken blade penetrated the wooden baffle and penetrated three-thirds of the wood.
Zhang Yang released the pedal and the lathe stopped rotating. He relaxed his sore knees and thighs and then noticed the emperor beside him.
"Your Majesty, when did you come?"
"I have been here since you started." Li Shimin looked at the lathe in front of him with a dark face, "Is this the only use of this thing?"
Zhang Yang simply picked up the small bench beside him and sat down to relax his thighs. "This is just one of its uses. I will modify it in the future to make it better."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Li Shimin nodded again and said: "I have always admired people who have confidence."
Li Tai observed the chamfers that had been cut on the lathe, "Is this all right?"
Zhang Yang raised his eyes and said, "It's not enough, the knife has broken."
"Come here!" Li Tai shouted toward the door, "Bring some more knives."
What knives Li Tai's bodyguards can bring are nothing more than horizontal knives and daggers. Daggers can be substituted, but the blades are made very thin for the sake of lethality.
Such tools are not suitable for cutting.
"Brother-in-law, are you looking for something suitable?"
Zhang Yang looked at the knives on the floor, "The back of the dagger is still useful, let me try it."
The knife was reinstalled, and this time Li Tai's bodyguard stepped on the pedal, and the bearings inside the lathe began to rotate again.
Li Shimin drank tea and watched with interest. After all, it was a novelty, so it was refreshing and fun to watch.
The blade of the dagger is fixed in the splint, and the back of the blade slowly approaches the chamfered edge.
Zhang Yang slowly moved the blade, Li Tai held up the kettle and poured the water down, repeating what he had done before.
"The speed is not enough, pedal faster."
Hearing this, the guard gritted his teeth and pedaled harder, because this pedal was connected to a belt, and the more he pedaled, the harder it became and the faster the speed. He gritted his teeth and turned red.
After holding on for half a stick of incense, the guard fell to the ground with his thigh stretched out and could no longer move due to the sudden severe cramping pain.
Li Tai said again: "Substitute!"
"Here!"
Another guard came on, also stepping hard on the pedal. The cutting continued with sparks popping up and iron filings falling down.
By the time the chamfering on one side was completed, five guards were already paralyzed from exhaustion.
Zhang Yang changed it to one side and said, "There is one more side to finish, just hold on for another hour."
When they heard that it would be another hour, the guards turned pale. This job was really not done by humans.
Li Shimin said solemnly: "Guards are also human beings and need to rest."
Li Tai now has the attitude of making a mistake, and the completion of the steam engine has reached the most critical stage, so he is naturally eager for success.
Only Li Shimin, who was leisurely watching the excitement, picked up the drawing again as if he was admiring a painting.
Li Zhi passed by the door of the workshop on his skateboard. Seeing that his father and his brother-in-law were there, he also walked in and showed his attitude of watching the fun.
Li Lizhi came with a bowl of grapes, "Father, the grapes were just picked today."
Several people sat down again and ate grapes.
Zhang Yang warned, "This thing needs to be replaced from time to time because it will rust. It's best to make a few more parts like this so that they can be used interchangeably."
As long as the current technical problems can be solved, Li Tai will listen to his brother-in-law's arrangements no matter what.
Zhang Yang replaced the pedals and the cowhide belt in the lathe. Since the lathe was built, it has not been used so intensively. The cowhide belt is very worn and will break if it continues to be used.
After replacing the cowhide belt, take out a push-pull box from a corner of the workshop and put the belt on the hub of the push-pull box.
Li Shimin was talking to his daughter Li Lizhi.
Li Tai looked at the drawings and pondered.
A group of guards collapsed on the ground from exhaustion.
Only Zhang Yang was still busy replacing wheels and belts.
I only have five leather straps left by me. The toughest leather on a cow is only on the back of the cow. A cow can only make two such leather straps at most.
It hurts every time I change one.
In the past, the pedal was installed so that I could use the lathe by myself, so I only needed to use my hands and feet.
Nowadays, the intensity of use is so high that someone needs to cooperate.
The belts and wheels of the lathe were replaced, and Li Tai's bodyguards also recovered some strength.
Li Shimin watched from beginning to end. He had to say that Zhang Yang's craftsmanship was indeed very good and he was able to create such things. Even Yan Liben did not necessarily have such accomplishments.
This kid still has a lot of skills in his belly that he hasn't used yet.
A humble workshop can actually exhaust so many people.
The lathe started to rotate again, and the guard pulled the wooden pole again and again. With each pull, the force of the wheel rotation in the lathe would pull it back, so each pull would be more difficult, and the belt would become tighter and tighter.
.
In order to use their strength better, in order that His Highness the King of Wei could build a steam engine, and in order that the hard work and sweat of the past three years would not be in vain, these guards took turns one by one, gritting their teeth and insisting on pulling the lever to make the inside of the lathe rotate.
He stepped on the side of the lathe, lying on the ground, using his feet and knees to pull out the lever. He continued like this, without fear that his back would be scraped against the ground.
Another hour passed, and it was getting dark at noon. I pulled the lever for the last time and slowly stopped the lathe.
Zhang Yang took out the inverted air valve and said, "Try again."
Li Tai held it with both hands, "This time we must succeed."
The five guards now were paralyzed from exhaustion again. This time, three of them had bruises on their backs, another had his waist broken, and the remaining one was lying outside vomiting.
Li Shimin was amazed that making a single part could be so brutal.
After such intense abuse, most of the lathe was ruined. Zhang Yang felt that it needed major repairs if it was to continue to be used.
Li Tai took out Lishan's unique vernier caliper and checked the size. After confirming that it was correct, he hurried away with it.
Several guards also followed suit.
Li Shimin also followed out of curiosity.
Next to the blacksmith shop in Lishan, there is a tin house. To be precise, it is a very huge steam engine. This steam engine has had many parts replaced and tested many times, including the internal pipes.
This is the reason why Lishan's technology has stagnated in the past three years, and it is also the reason why there has been no new thing in the past three years. Lishan has invested most of its material resources and manpower on this steam engine. Niu Chuang and others, in addition to their daily maintenance work in the village,
The assembly line is where most of the effort is spent. Three years of technical hard work has created such a big thing.
Li Shimin was confused when he first saw this thing. He frowned and asked, "What is this thing for?"
Li Tai wiped the sweat from his forehead, installed the air valve in the inner cavity and confirmed that the preparations were correct, and then explained: "This is Lishan's biggest achievement. My father is optimistic that the Tang Dynasty will become rich and powerful in one fell swoop."
After that, the fuel tank of the steam engine began to burn, and black smoke kept coming out of the chimney above. Everyone was looking forward to the water inside boiling. When white smoke came out of the second chimney above, Li Tai pulled the rope on the side, and the three
The chimneys are smoking together.
The steam engine sounded a loud whistle, which resounded throughout the countryside, causing everyone around to stop what they were doing and look for the sound.
Everyone held their breath and looked at the wheel at the front. After another hour of burning, a strange noise came from the interior, and there was another loud whistle.
Finally, at this moment, everyone stared at the wheel at the front, until the wheel started turning, and everyone cheered.
"Ah!" Niu Chuang howled loudly with excitement.
Li Shimin stood there in a mess, not knowing what they were excited about. They seemed to have done something extraordinary.
I don't understand what's going on.
Everyone had tears in their eyes. It has been three years. These three years have been too painful.
"Brother-in-law!" Li Tai shouted towards Lishan, wiping his tears while running all the way towards Lishan, shouting loudly towards the mountain: "Brother-in-law! Brother-in-law! Brother-in-law..."
