The next day, under the escort of hundreds of cavalry, Fang Nan and Wang Mu came to Foshan.

Tang Bei and Wang Da Hammer didn't know that Fang Nan came to Foshan so soon, and when Fang Nan and Wang Mu came to the "Steam Engine Research Institute", Tang Bei and Wang Da Hammer were leading a group of researchers to test the first practical steam engine in the venue, that is, to conduct a pumping test.

It wasn't until Fang Nan and Wang Mu walked into the venue that researchers discovered that the Metropolitan Governor had arrived.

"The Governor is here." The researcher who was the first to discover Fang Nan's arrival shouted.

Soon, other people in the venue reacted one after another, turned around and looked in the direction where Fang Nan was, and Tang Bei, as the head of the project team, and Wang Dazhui greeted him together.

"I've seen the Metropolitan Governor, but I didn't expect the Metropolitan Governor to come so early, and we weren't prepared." Tang Bei touched his head with his right hand and said very embarrassed.

At this time, Tang Bei's clothes were a little dirty because of contact with the steam engine, so he met the Metropolitan Governor like this, which made Tang Bei's cheeks a little hot.

"It doesn't matter, Wang Mu and I came here to see the first practical steam engine you built." Fang Nan waved his hand disappreciatively.

Knowing that the Metropolitan Governor attached great importance to the steam engine, Wang Dazhui immediately stretched out his hand in the direction of the steam engine and introduced the steam engine to Fang Nan.

"Metropolitan Governor, please here, this is the first practical steam engine we have built, seven days have passed since it was built, and we will use this steam engine for some time every day, Xiao Zhang, how long has this steam engine been working until now?"

As soon as Wang Dazhu's voice fell, the researcher who called Xiao Zhang flipped through the notebook in his hand, and said in a few seconds: "Dadu, our steam engine has been working for a total of thirteen hours and two quarters of an hour. ”

Hearing Xiao Zhang's words, Fang Nan nodded slightly, a total of thirteen hours of work plus two quarters of an hour, barely a practical steam engine, the specific situation has to continue to be tested, the real practical steam engine is obviously more than this working time, at least hundreds of hours of stable work is required.

However, Fang Nan didn't demand too much, compared to the previous steam engines that had failed to build, this steam engine that had worked for a total of thirteen hours and two quarters of an hour was already very successful.

Fang Nan approached the steam engine and took the appearance of the steam engine into his eyes, the steam engine in front of him was a little rough, the main body was a boiler that boiled water to produce steam, the lower part of the boiler was used to make a fire, the above the boiler was a cylinder, and above the cylinder was a piston device.

Steam is generated from the boiler into the cylinder, cold water is used to condense the steam in the cylinder to create a vacuum, and the air pressure on the other side of the piston pushes the piston to make the piston work back and forth, thus generating power to drive the pump to pump water.

The structure of the steam engine is very simple, but it took Tang Bei and Wang Dazhui more than half a year to build such a practical steam engine, spending a lot of time on studying the principle of the steam engine, and more time on building a steam engine.

The most important point on the steam engine is the air tightness, because of this alone, it makes Wang Da Hammer and a group of craftsmen have a pain in their heads, once the air tightness is not good, the steam runs away, then the steam engine is a failure.

With the efforts of Wang Dazhui and a group of craftsmen, the problem of air tightness of the steam engine was finally solved, although it was said that one failure after another was created, but in the continuous failure, the air tightness of the steam engine became better and better, and the quality was getting higher and higher, and finally there was this barely practical steam engine in front of Fang Nan.

Wang Mu is also looking at the steam engine that is being worked, Wang Mu knows some about the steam engine, including the principle of the steam engine, Wang Mu knows that the teacher attaches great importance to the steam engine, and can also feel the huge role of the steam engine.

Hydraulic machine tools can allow Foshan Arsenal to increase the production of firearms, that is the power of water, and hydraulic machine tools have great limitations, hydraulic machine tools must stay next to the river, and the whole hydraulic machine tool is so big.

This steam engine is also the power of water, but it does not have the limitations of hydraulic machine tools, it can be put in various places, and the volume of the steam engine is much smaller than that of the tall waterwheel.

"It's a good thing." Wang Mu thought in his heart.

Watching the steam engine work, watching the steam engine pumping water, all kinds of praise came out of Fang Nan's mouth, which made some young people in the project team very embarrassed, and also made the craftsmen who were no longer young speechless with excitement.

They just built a machine, but they didn't expect to be praised so much by the Metropolitan Governor.

Of course, verbal praise is not enough, there are also physical rewards, ordinary researchers are rewarded with ten acres of fertile land and thirty taels of silver, and the group leader and persons in charge like Wang Dazhui and Tang Bei are rewarded even higher.

When Fang Nan read out the reward for everyone, the project team members shouted excitedly: "Long live the Grand Governor!" Long live the Grand Governor! ”

After a while, Fang Nan, Wang Mu, Tang Bei, and Wang Dazhui sat together.

"The steam engine you are building now has preliminary practical value, and then test the time limit, if it is qualified, it can be built in batches and sent to the mine to pump water."

"Understood." Tang Beidao.

"You still have initial success in the research of the steam engine, but in my opinion it is not enough, the steam engine you have built can only be used for pumping water, the efficiency is still relatively low, and the workmanship is not very stable.

I need you to continue to study the steam engine, and develop a steam engine with higher efficiency and more stable workmanship, at least this steam engine can be used in machine tools, make steam-powered machine tools, and replace hydraulic machine tools.

This new steam engine is more difficult to build and will require more time to research, and I'll be here often to help you. ”

Hearing Fang Nan's words, Wang Dazhui directly affirmed: "With the help of the Grand Governor, we will definitely be able to build a better steam engine." ”

Wang Dazhui said so, he also thought so in his heart, and Tang Bei also did the same, the two of them trusted Fang Nan very much, this trust was used before, and when they researched and built hydraulic machine tools and then steam engines, this trust was even more.

No one could have imagined how magical these machines were until they had seen hydraulic machines and steam engines, and almost everyone in the project team was immersed in the study of steam engines.

Whether it is a hydraulic machine tool or a steam engine, it is proposed by Fang Nan, providing principles and sketches, and will come over every once in a while for guidance, it is under the guidance of Fang Nan that the project team can build a steam engine with practical value in more than half a year.

Without Fang Nan's guidance, this time might have been extended to more than a year, and if there were no principles and sketches provided by Fang Nan, the steam engine would not have appeared on the land of China for hundreds of years.
