When Fries led a group of scholars of the Greek school to Broken Leaf to join Li Lu, among them, there was a descendant of the ancient Greek scientist Hero, Riotinis, who once showed Li Lu a strange machine that was absolutely strange and ingenious in the eyes of the scholars and doctors in the Central Plains, this machine was called "steam ball", this "steam ball" structure is very simple, it is connected by a hollow ball and a closed pot filled with water with two hollow pipes, The water boiled by heating the bottom of the pot and then turned into water vapor, which then entered the ball through the tube, and finally the water vapor was ejected from both sides of the ball and made the ball rotate.At that time, Li Lu saw it, he was quite shocked, in his opinion, this is not just a delicate toy, but the most primitive steam engine, he said to those scientists that if time passes, steam power will inevitably become popular, and this small "steam ball" may trigger a power revolution, he hopes that someone can continue the research of Hiro, at the same time Li Lu also offered a reward, if anyone can put the steam power device into practice, he will let him gain fame and fortune.From then on, Riotinis and his students from Broken Leaf University, as well as some folk invention enthusiasts, all focused their energy on what Li Lu called a "steam machine", and even Daomen and Mojia, as well as scientific giants such as Song Yingxing and Shen Kuo, were involved.The first to gain was a Taoist doctor, this Taoist priest named Yunping wanted to make a high-pressure vessel suitable for disinfection, he got a copy of Hiro's "Mechanical Collection" from Riotinis and Hiro's invention of chain pumps, air pumps, piston pumps and other machines, called his friend, Xiang Libin, who was born in Momen, to study together, and the two of them developed a strange container, when they dedicated this Dongdong to Li Lu, Li Lu said in surprise, "Isn't this a pressure cooker??"
”Yes, this strange container invented by Yunping and Xiang Libin is a pressure cooker, the most critical part of the pressure cooker is the safety valve, the two of them ingeniously invented a lever safety valve, which applies a heavy object at the far end, and the force point of the steam pressure to push the steam valve is a short force arm, when the pressure of the pressure cooker exceeds the design value, the steam valve can be pushed up to discharge part of the pressure, and then fall back to the distance after balancing.When he saw this safety valve, Li Lu said that he could make a piston steam engine on the basis of this safety valve, although Yunping and Xiang Libin did not put Li Lu's idea into practice, but they spread Li Lu's conjecture.After Song Yingxing and Shen Kuo visited the pressure cooker built by Yun Ping and Xiang Libin, they carefully studied Li Lu's conjecture and found that this plan was still feasible, but because of the lack of manufacturing technology to make a good airtight piston, they abandoned the piston structure in the plan and built a steam engine that could be used in mines, which was mainly used to help those mines extract groundwater.Their steam engine was redesigned with two parts: a boiler and a closed working vessel.The working principle is very simple, that is, first through the boiler to heat the water, so that the steam fills the working container, and then close the steam hole, so that the water vapor in the working container condenses, forming a local vacuum, when the container is connected to the mine water, through the external atmospheric pressure, you can "suck" the water to a high place, the principle is to rely on the atmospheric pressure to press the water up, so the lifting height of the water is related to the atmospheric pressure, about three zhang.In order to send water to a higher place, Song Yingxing specially designed a steam pressure device to send water to a higher place, this set of machines, named "Friends of the Mine" by Li Lu, and Li Lu issued Song Yingxing and Shen Kuo two people can be said to be the first steam engine patent in the known world.This set of steam engines was used in large quantities in the mine by Yinghua Mining, a subsidiary of Wu Mei's Department of Commerce, but this "friend of the mine" has many problems, the most important thing is that the efficiency of this steam engine is very low, and it needs to burn a lot of coal in order to maintain the operation of the machine, but fortunately, it itself is used for coal mine pumping, and coal is.However, it relies on pressure to transport water, and due to the lack of material manufacturing and welding technology, the pipeline breaks and explodes from time to time, and at the same time relies on atmospheric pressure to lift water, and the maximum lifting height is about three zhang, which limits its use range.Although Song Yingxing and Shen Kuo thought of a lot of methods, but to no avail, just when the two science and technology tycoons were meditating, a steam engine repairman named Sun Xin in a Kazhou coal mine (Kazhou was about equivalent to the Karaganda area of Kazakhstan in later times) solved a problem that neither of them had solved.Sun Xin only has a primary education, he once worked as a blacksmith in a mechanical workshop, and then by chance, he became a steam engine pump repairman in the Kazhou coal mine owned by Yinghua Mining, when repairing the steam pump, he found that the condensation of steam into the lower part of the piston and the piston and the connecting rod can produce movement, he thought that this idea is installed on the set of "Friends of the Mine" he served, wouldn't it be possible to form a better machine?
Sun Xin is an idea-minded and hands-on person, he first made a scale-down model, and after finding that his idea was completely feasible, he was ready to get this set of devices out, but the biggest problem came, he was just a maintenance worker, not much money, and his boss also sneered at him, saying that even the masters of Broken Leaf University and the Science and Technology Department couldn't solve the problem, you can solve it with a small maintenance worker, and said that Sun Xin would not be provided with funds for the experiment.Sun Xin was angry, and wrote his plan and the sneers of the Yinghua mining manager on a letter, and threw it into Jinyiwei's special mailbox, because Li Lu attaches great importance to scientific and technological inventions, so after seeing Sun Xin's letter, Carzhou Jinyiwei did not dare to delay, and they sent Sun Xin's letter to Broken Leaf quickly.When this letter arrived at the broken leaves, Li Lu was worried about what excuse he would not go to Chang'an once Li Er hung up, when Li Lu opened Sun Xin's letter, he was surprised to see that the steam engine designed by Sun Xin was already a relatively mature steam engine program, and this plan was more advanced than the previous Song and Shen two people's plans in that the pressure of this machine was no longer limited and the steam pressure, as well as the internal condensation nozzle and automatic valve actuation device on his plan were simply genius-like ideas, Li Lu couldn't help but applaud Sun Xin's design.But when Li Lu saw Sun Xinfa's complaints, he couldn't help but be furious, "These bastards, they can't do it themselves, and they still have the face to ridicule others......"
When Li Lu was angry, it happened that Wu Mei walked in, she was holding a cup of strong coffee, "What's wrong?"
Lang Jun, who you off?
”When Li Lu heard Wu Mei's voice, his anger calmed down, and he pushed Sun Xin's letter in front of Wu Mei, "Mei Niang, look at it, your good subordinates .....""
My good men??"
Wu Mei was taken aback at first, she took Sun Xin's letter, quickly skimmed it, and then became angry, "This Qin Bo is really a bastard......
Lang Jun, I will sign an order to remove him from his post......
"Yinghua Mining is a directly subordinate enterprise of the Department of Commerce, and Wu Mei naturally has the right to remove this Qin Bo from his post."
Mei Niang, you have to check this Qin Bo well, well, and our stall is getting bigger and bigger, and there will inevitably be some problems, it's not terrible to have problems, it's terrible not to solve them......"
Li Lu took a sip of coffee, "You have to take advantage of the investigation and punishment of Qin Bo, and take care of the business under our family name and Wang Ting's name....."
These enterprises mentioned by Li Lu are roughly quite state-owned enterprises in later generations, and after a long time, some problems have also been used to appearing, such as this Qin Bo is an excellent example."
Well, these people are actually moths, if they go to eat others, I Wu Meiniang can't control it, and I don't want to take care of it, but I want to make a living under the banner of the two of us, and I still want to be moths and dig the corners of our family, this is what my Wu Meiniang can't accept....."
This girl is a ruthless person, and she is very good at anti-corruption.Soon Sun Xin was taken to the broken leaf with his drawings, and the sneering Qin Bo also after the investigation, found that this guy was not only incompetent, but also greedy, and he was guilty of all the crimes he could, except for the crime of collaborating with the enemy, he was all guilty, and when he searched his house, people were surprised to find an astonishing amount of gold and silver in the wall of his house, and when Jinyiwei interrogated him, this Qin Bo actually said that because the flying money was easy to find, all the stolen money he took bribes and embezzled was replaced with gold and silver......
Qin Bo's fall heralded the arrival of a new wave of anti-corruption in the "state-owned enterprises" of the British Kingdom controlled by Li Lu, but their owner Li Lu did not put his mind here, but pulled Sun Xin and Song Yingxing, Shen Kuo, Riotinis and a large number of experts began to tackle the steam engine, it turned out that the steam engine Li Lu wanted was not this kind of steam engine that was only used to pump water, he wanted the kind of steam engine that could be widely used."
We can design a separate condensing device, so that there is no need to reduce the temperature of the cylinder to room temperature and then reheat, maybe we can improve the efficiency ......of the heat engine," Li Lu said to a group of scientific and technological giants, "I suggest that Sun Xin's plan continue to be improved....."
There is another problem, that is, the transmission system..... you see, the movement mode of my scheme is that the piston is doing reciprocating motion, how to turn this reciprocating motion into a motion that can rotate, this is a big problem......
"This is Sun Xin.""
Well, we can use cranks and gears to design a transmission system and accept the work ......done by the piston," Song Yingxing thought about it and said."
We can also design the cylinder to be bidirectional, so that the air intake on both sides of the cylinder will definitely improve efficiency....."
Shen Kuo is not far behind."
If you want the two-way cylinder to run smoothly, a set of parallel four-rod linkage is indispensable....."
Riotinis also offered his opinion.In the end, with the efforts of Li Lu and several science and technology masters present, an epoch-making machine was tossed out by them, the appearance of this machine marks that Li Lu has opened the door of the industrial revolution, just when Li Lu was too happy, he didn't pay attention to the system for a long time, but reminded him, your civilization point balance is not much, please hurry up and recharge, Li Lu quickly logged in to the background to check, don't look at it I don't know, I was startled when I saw it, it turned out that because of the appearance of the steam engine, the system must be upgraded, And the civilization points required for upgrading are an astronomical amount, and this number is so big that it can eat him, what should I do??
What is the fastest way to get money?
This still needs to be asked, naturally it is robbed, it seems that it is time to start a war again, thinking of starting a war, Li Lu's mind lit up, he came to the expedition himself, if Li Er hangs up, he doesn't have to go to Chang'an.
