"It's moving, it's really moving, this iron goblet ..."

"Get the coals ready, watch out, don't let the fire go out ..."

"The people next to me let me know, don't squeeze here, this boiler will be hot ..."

In mid-January, the snow was clear after the snow, and the cold was fading. The snow on the ground had not completely disappeared. The courtyard of the blacksmith's workshop in Yan's house was already full of heat and bustle. A large number of people surrounded the blacksmith's workshop. An eye widened, watching the "iron gob" flywheel on the open space in the middle of the yard slowly turned.

Yan Dechang, Zhou Tiezhu, and dozens of apprentice disciples in the blacksmith's workshop, a bunch of stewards of the Yan family, plus Yan Liqiang, Shi Changfeng, Shi Dafeng, Shen Teng, Lu Peien, and Qian Su made from Huanglong County The old craftsmen and craftsmen who worked with several blacksmith workshops, and finally a disciple of Wen Zhaolun and Lingshan School, all surrounded the yard, watching the "iron goblet" sent by Lingshan slowly after adding water to the fire, Moved.

Except for a few people such as Yan Liqiang and Wen Zhaolun, after watching the "Iron Golem" moving, everyone was in an instant, and Zhou Tiezhu's voice shouted with excitement and trembling.

Yan Dechang, who had beaten iron for a lifetime, was stunned when he watched the flywheel turning faster and faster. The whole man muttered to himself, "I have beaten iron for a lifetime. I did not expect that the fire and water could make the iron golem move by itself. stand up……"

Qian Su and several old blacksmiths and craftsmen who came from the Manufacturing Bureau, staring at the rotating flywheel at this time, could not say a word, just like seeing something incredible, as for other Changfeng Feng The expressions on people's faces are basically the same at this time.

Yan Liqiang was standing next to the steam engine that had just been assembled, watching the fast-moving flywheel, and glanced over the parts of the steam engine, and his eyes were a bit surprised-at first glance, this A steam engine is like a one-meter-high stove. Below the steam engine is a metal seat and frame. On the left side of that frame is a boiler that resembles a stove's ignition. The boiler is made of iron. Above the boiler, there is also a bright yellow cylindrical water tank made of brass. The water tank is about one meter long and the bucket is thick. On the water tank, there are several copper pipes. Some copper pipes are filled with water. Some copper pipes are vented and deflated. In the middle of the vented copper pipes, there is a manual valve that can adjust the amount of intake air. This intake pipe is connected to the most important cylinder of the steam engine. Above the cylinder is the piston and The crankshaft connecting rod, a circular rotating flywheel with a diameter of about 50 cm, is on the other side of the crankshaft connecting rod. As the piston in the cylinder moves, the flywheel is also fast under the action of the connecting rod. Turned up.

But what really surprised Yan Liqiang was not these, but the device that condenses the steam input into the cylinder under this steam engine. We must know that in the previous life, this condensing device was long after the steam engine was invented The original steam engine made by Watt had two obvious shortcomings. One was the discontinuity and slowness of the piston. The second was the low utilization of steam and the waste of raw materials. The most important reason for this problem was steam. Condensing in the cylinder, Watt's biggest contribution to the steam engine is to change the traditional steam engine's condensation method from in-cylinder condensation to out-of-cylinder condensation. After Watt completed this improvement, the basic mechanism of the steam engine was completely stabilized, and then it became popular. .

Yan Liqiang originally thought that Zhang Yourong's first steam engine would not think of condensation outside the cylinder, but what he didn't expect was that this steam engine sent by Lingshan had already adopted the condensation outside the cylinder. In this way, The reliability and stability of this steam engine has been greatly improved, and it can definitely reach the practical standard.

Yan Liqiang secretly was a little surprised, Zhang Yourong is indeed Zhang Yourong, but just after being punctured by himself, after one year, this steam machine built by Zhang Yourong is very complete. Right now, this machine built by Lingshan School Qianjitang The steam engine is very close to the mature single-cylinder steam engine in its mind. Although some details are rough at first glance, the basic mechanical structure and use functions are fully equipped.

Operating the steam engine in front of them were two disciples of Lingshan School Qianjitang. Wen Zhaolun was standing next to him, and looked proudly at the iron pan made by Lingshan School Qianjitang. Before Zhang Yourong returned to Qianjitang, At that time, I highly respected Yan Liqiang and once told Wen Zhaolun that the accomplishments of Yan Liqiang's organs and things were unfathomable and may be above him. Although Wen Zhaolun always admired Zhang Yourong's skill very much, he praised Zhang Yourong. If he did, he had some reservations in his heart. Before he came to Ganzhou, he didn't believe that a boy in his twenties could achieve accomplishments in the way of organs and things like the great master Zhang Yourong of the First Han Empire. After the state, in Tianchi, Canglong Mountain, I have seen Yan Liqiang's ability on the bow road. Wen Zhaolun did look at Yan Liqiang and was shocked. But when it comes to the way of organizing things, he still feels that Yan Liqiang cannot be more powerful than Zhang Yourong. Zhang Yourong said that Tie Yan's idea was conceived by Yan Liqiang. Even after meeting Yan Liqiang, Wen Zhaolun always felt strict. Strong perhaps just a blind cat run into dead rat, a flash head had a concept, really powerful figure, of course, they recruited thousands of machines Tong Zhang.

The look and shock on the faces of the people made Wen Zhaolun, the deputy owner of Qianjitang, very satisfied. I remember when he first saw this thing made by Zhang Yourong, it was almost the same look. The face of that dry man was stunned. It seemed to Wen Zhaolun that it was like a speechless praise to Lingshan School and Qianjitang, which made him very useful, and when Wen Zhaolun's eyes turned to Yan Liqiang's face, the deputy chief of Qianjitang For a moment, because of the look on Yan Liqiang's face, there was no shock at all. Instead, he looked at this "previously no-man" machine made by Lingshan School of Qianjitang with a kind of playful look. .

Seeing something that no one can make, shouldn't it be shocked and admired? Examine? what does that mean?

Wen Zhaolun's mind was a little unhappy, "Ah ... heh ... what do Yan Yanzi think of this water-fire machine created by Lingshan to send Qianjitang?"

The water-fire machine, which sounded weird at Yan Liqiang, was the name given to this steam machine by Lingshan. To put it simply, it was a machine that could be driven by the power of water-fire.

"Brother Zhang really deserves to be the Grand Master of the First Institution of the Han Dynasty. This ... water ... water machine is definitely the first silver continent, admire, admire!" Yan Liqiang praised with a smile.

After hearing Yan Liqiang saying so, Wen Zhaolun finally showed a smile on his face, and felt that Yan Liqiang was still modest.

"Li Qiang, how can this flywheel slow down ..." After staring at the steam engine for a long time, Yan Dechang couldn't help asking a question.

"Oh, it ’s easy to slow down the flywheel. Father, you can see that the valve on the copper tube can be controlled. Pull up the valve, the flywheel will slow down, open it bigger, and the flywheel will rotate faster. Some ... "Yan Liqiang said as he walked over, hands on, and pulled the steam valve connected to the boiler's copper pipe to demonstrate it.

Seeing Yan Liqiang's hands, Wen Zhaolun and the nearby Lingshan faction's disciples stunned for a moment. They haven't said how to control the water fire machine. How can Yan Liqiang know at a glance?

"Then why can this valve control the speed of this flywheel?" Zhou Tiezhu asked, scratching his head.

"That's because after the water in this copper water tank is heated, the steam generated will enter the cylinder from this copper pipe. This valve controls the size of the steam in the copper pipe, the steam is small, and that of the flywheel The speed will be slow, and the speed of the flywheel will be fast! ”Yan Liqiang pointed to the steam engine and explained,“ just be careful when using this thing. If the boiler under this water tank is still on fire, this valve cannot be completely closed. After the vent valve is closed, a vent switch here must be opened. If all the valves are closed to burn water, the water tank will explode over a long period of time, which is very dangerous. If there is someone nearby, there may be death or injury ... "

"Oh, this thing will explode?" Zhou Tiezhu asked in surprise.

"of course!"

Wen Zhaolun was already surprised, UU reading www.uukanshu.com because when Qianqitang started to research and manufacture this thing, it really happened like Yan Liqiang said, something happened, but fortunately there was no injury in that accident. To the people, when the boiler exploded, there was no one around, just to make a workshop a mess, after that, Zhang Yourong thought of installing a vent for this boiler ...

"I heard the host said that Yan Zizi's accomplishments in the way of organizing things are extraordinary. Then, when he looked at this water-fire machine, can he guess where our church master spends the most effort?" Wen Zhaolun was a little dead My heart asked again.

Yan Liqiang smiled and pointed to the inconspicuous condensing device under the cylinder. "The earliest water-fire machine manufactured by Qianjitang did not have this thing. It must have been made by Brother Zhang last. It is also Zhang My brother experimented countless times and spent a lot of time and energy. I don't know if I guessed right! "

"Ah ..." Wen Zhaolun stared at Yan Liqiang with a stunned look. The next few disciples of Lingshan School looked at Yan Liqiang's eyes. It was like seeing a ghost. As soon as the so-called expert reached out, he knew if he was there. , And instantly calmed down Wen Zhaolun and a few disciples of Lingshan School.

"Uncle Qian, can you also make this thing on the side of the Manufacturing Bureau?" Yan Liqiang turned his head and asked Qian Su ...
