Take the mall to Datang

Digging a well is a time-consuming and labor-intensive task. Now it can be done within a day. No one would believe such a thing in Chang'an City. The original force of steam is very simple, but it is more difficult for people in Datang to understand, Li Dejian Those who have personally participated in the manufacture of steam engines like Li Deju know that steam engines are not mysterious at all.

With the steam well drilling machine, Wulizhuang became lively again. Several new wells appeared in Wulizhuang within a few days. In the future, it is no longer necessary to hit around a small well, and life will be more convenient in the future. This matter soon spread to Silizhuang and Sanlizhuang.

A week later, the Military Weapons Supervisor came, not because of the steam engine, but because Yuan Shan hadn't been to the Military Weapons Supervisor for a week, Xin Jiancheng came here to report some things in person.

But when he came to Yuanjia Manor for the first time, he was shocked by the changes in Wulizhuang. He didn’t expect that a small Wulizhuang would have concrete roads, and the houses the farmers lived in were the worst. They were brick-based wooden houses, which were better. They are all built of bricks and stones. This kind of architectural magic is better than the houses in the rooms of Chang'an City. I really don't know where these people got so much money. ,

He also remembered what Zuoqiu had said to him. According to legend, their Yuan Zhengjian was a boy who scattered money, and those who followed him would not be poor. It was true when I saw him today. When I first entered the manor, I saw a black man The gigantic monster made a thumping sound.

"What is this?" Xin Liangchou was a little frightened.

"Steam engine." Yuan Shan walked over and said.

"Yuan Zhengjian, I didn't expect you to be here." Xin Liangchou asked curiously.

"Aren't you here to see the steam engine digging a well? What are you doing here?" Yuan Shan said.

"The lower officials are here to report to you the production situation of the Military Weapons Supervision. The next thing needs to be handled by Yuanzheng Superintendent." Xin Liangchou said.

He was also speechless. The Yuan Shan in front of him was an official who fished for three days and posted nets for two days. He had never seen such an official.

"Xin Jiancheng, I will return to the prison in a few days. Besides, the Military Weapons Supervision can maintain normal production. I am very relieved to have you there. I believe that you will be able to do well in the next thing. You have to believe Myself." Yuan Shan continued.

"Yuan Zhengjian..." Xin Liangchou wanted to say something, but Yuan Shan had already shifted his attention to the steam engine, seeing that something was wrong with the boiler of the steam engine, he quickly ran over.

"Quickly vent!" Yuan Shan suddenly shouted.

Chapter 219 Boiler Pressure

Hearing Yuan Shan's cry, Li Dejian moved the air release valve quickly, and then heard a sound like a pressure cooker blowing out, like a train whistle.

Xin Liangchou was startled when he heard such a voice, and panicked.

"The pressure of the boiler is too high, and it keeps deflated." Yuan Shan continued to shout.

Li Dejian didn't let go of his hands, the speed of the cylinder gradually slowed down, Yuan Shan was observing the situation of the cylinder hard, and when the speed stabilized, he said: "Okay, turn off the ventilation valve."

The cylinder continued to work, and the speed of driving the flywheel stabilized. Yuan Shancai said to Li Dejian: "What did you do? Didn't you tell you to be optimistic about the speed of the cylinder, and it almost exploded."

"Teacher Yuan is my fault." Li Dejian said in a low voice.

At this moment, Li Deju ran over and said, "Mr. Yuan is not my brother's fault. I was the one who watched the cylinder. Just now, I rushed to solve the urgent need to urinate. Who would have thought that it was my fault that the temperature was too high."

Yuan Shan felt that the two brothers were quite responsible, since there was no accident, it was fine to criticize them, and then in the next 10 minutes, Yuan Shan was furious and scolded the two of them fiercely.

Even Xin Liangchou next to him felt very scared when he saw this vicious appearance, but he did not expect his Shangguan to be so hot-tempered.

In fact, Yuan Shan's behavior was also for the benefit of the two brothers. As far as the situation just now is concerned, if the boiler blows up, people will die. It would be good to install a pressure gauge on the boiler. It is not impossible to imitate the pressure gauge with the current technology, but it will take some time and rewards. All kinds of small parts can be processed and produced by Blacksmith Lu's apprentices.

After making up his mind, Yuan Shan instructed the two brothers in front of him again. They are the sons of Li Jing, let alone his father, Yuan Shan, and even their mother, Yuan Shan can't afford to provoke them. Heroes and heroes are all living a life of licking blood, what will happen to these two young men, then he will not be able to get along well in Datang.

It is only now that he realizes the seriousness of the matter. He has been using these two brothers as small workshop workers all along, and besides taking care of the meals, he has no wages. Thinking about him as a teacher, it seems a bit unreasonable .

"Forget it this time, scientific experiments are rigorous, and there will be no next time such a fatal mistake." Yuan Shan warned again sharply.

The steam engine is still working, the water well has not been tapped today, and the two brothers have lifted their spirits, Yuan Shan's criticism is still effective, Yuan Shan turned around as if to leave, but at this time Xin Liangchou came up and asked : "Yuan Zhengjian, I am very curious about this steam engine, can I know more about it?"

"Don't you like lighting fires and setting off cannons? Why are you also interested in steam engines? Your tastes change quite quickly." Yuan Shan joked.

"Yuanzhengjian, what is this thing used for?" Xin Liangchou asked curiously.

"Didn't you see that this machine is drilling a well? This is a steam well drilling machine, which converts heat energy into mechanical energy for work. If you see that the wellhead does not pass through this steam machine, you can drill a well in a day and reach a large area. It's deep, it's not too severe." Yuan Shan said.

"Excellent, as long as there is this steam well drilling machine, the common people will have no problem with water." Xin Liangchou said.

Yuan Shan didn't expect that Xin Liangchou would think about the common people of the Tang Dynasty, so he said: "Technology is the primary productive force, and Xin Jiancheng is the core of the future development of Military Weapons Supervision."

After Yuan Shan finished speaking, Xin Liangchou chose to think briefly, and then said: "Yuan Zhengjian, I understand, I don't know what kind of equipment this steam engine can be used to make for fighting."

As expected, Jian Cheng of the Military Weapons Supervision Department kept his words in mind. When he saw the steam engine, he wanted to put it into the battlefield. He thought that this Xin Liangchou would not be a war madman.

"Well, you may have misunderstood. This steam engine itself is a machine that provides steam power, not for making weapons. Its function has yet to be developed. For now, it is a good choice for drilling wells." Yuan Shan casually said.

"Yuanzheng Supervisor, I think the Military Weapons Supervisor should also have a steam engine." Xin Liangchou said.

"You have a good idea, but such a steam engine is expensive and takes a lot of time to build, so let's talk about it." Yuan Shan said casually.

In this era, there is no patent right. If you build another one and put it in the military department, there is no secret at all. This steam engine cannot be imitated before it is sold.

"Maybe there will be opportunities in the future, Xin Jiancheng, don't worry." Yuan Shan decisively rejected this matter.

The two chatted casually, Xin Liangcho's eyes were fixed on the steam engine all the time, Yuan Shan didn't bother seeing it, since he likes to watch it, let him watch it.

"Xin Jiancheng, don't go in that way, the boiler is very hot." Yuan Shan immediately reminded.

Xin Liangcho stopped his curiosity immediately, he still wanted to touch the cylinder, but Yuan Shan stopped him immediately.

Yuan Shan didn't expect this guy to be so curious, and he wouldn't feel at ease if Xin Liangchou stayed here, so he took him to the manor, and talked about the military inspector along the way.

The profitability of the horseshoe business has not been very good recently. Now the smithy is basically giving priority to the imperial court, and the purchase price is lower than the market price. Originally, the recycling price of the military supervision business was low enough. After the imperial court In this way, the horseshoes produced by the military inspectorate were directly confiscated by the court, and it was impossible to sell them alone. Compared with the prices of the two, the income was much less. This matter can be found in Whampoa.

Today, Xin Liangchou came here mainly to talk about this matter. After all, the horseshoe is an independent project of their military supervision, and it can be independently controlled by their supervision. To put it bluntly, it is like spending whatever they want, and Li Shimin brought it. The money can only be used for projects and daily expenses, and it is not easy to use at all.

This is a matter related to the interests of everyone in the prison, and it is also the reason why Xin Liangchou came here in person.

"The income from horseshoes is low, so let's change to another project. In the current state, the expenditure in the prison will be maintained for a period of time with the supply of horseshoes from the imperial court. Next, we will make a long-term investment, but the income will be dozens of times higher than that of horseshoes. " Yuan Shan said confidently.

"Yuanzhengjian, what is this long-term investment project you are talking about?" Xin Liangchou asked impatiently.

"It's still a secret now. You can go back to the prison and continue to supervise the production. I'll be there in a few days." Yuan Shan said.

Xin Liangchou saw that he couldn't persuade Yuan Shan to go back now, so he left tactfully, but he was still so curious about the steam engine, and before leaving, he ran over and looked at it for a while before giving up.

Chapter 220 Bargaining

Knowing the problem with the steam engine, Yuan Shan approached Tiejiang Lu and gave him the blueprint of the pressure gauge, and asked him to start working on this thing immediately. The parts of the pressure gauge seem to be quite a lot, such as springs, pointers, dials, and movements. , Lining rings, excuses, and connecting rods are actually not complicated, all you need is some patience to build and polish.

With the blueprint provided by Yuan Shan, facing the sample of the pressure gauge, Lu Tiejiang decided to make it by himself. He will now refine the more complicated things you make. After getting the blueprint, he is ready to start work. Yuan Shan saw that Lu Tiejiang was so excited , I still held him back, and told him about the Force first, so that I could have a better reference when building and assembling.

"Master, don't worry, give this thing to me and I will definitely make it today, but the spring inside is too small, and it is very different from the large springs of rich and expensive cars made in the past. I am afraid it will be difficult. There is also this There is no transparent colored glass workshop either." Lu Tiejiang said.

In fact, this kind of small spring is not only difficult, but it cannot be made with the current technical means. The glass on the pressure gauge is not a problem for Yuan Shan, so Yuan Shan said: "Let's make the easy one first. , spring and glass I will solve."

"Okay, I'll start building this thing right now," Blacksmith Lu said.

Yuan Shan is looking forward to the production of this pressure gauge. With him, the danger of the boiler can be reduced.

It is difficult for such an eye-catching behemoth of the steam engine not to be known, especially since the number of wells in Lantian County began to increase, and the news that one well could be drilled a day was quickly spread, and within a few days, the entire city of Chang'an learned about it. information.
