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

Tang Bei and Wang Daechui didn't know that Fang Nan would come to Foshan so soon. When Fang Nan and Wang Mu came to the "Steam Engine Research Institute", Tang Bei and Wang Daechui were taking a group of researchers to test the first practical steam engine on the site, which was to conduct water pumping tests.

It was not until Fang Nan and Wang Mu walked into the site that researchers discovered that the Grand Commander had arrived.

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

Soon, the others in the venue reacted and turned to look in the direction where Fang Nan was. Tang Bei and Wang Dachui, the head of the project team, met together.

"I have seen the Grand Governor, but I didn't expect that the Grand Governor came so early, and we were not ready." Tang Bei touched his head with his right hand and said embarrassedly.

At this time, Tang Bei's clothes were a little dirty because they were in contact with the steam engine, so they met the governor like this, which made Tang Bei's cheeks a little hot.

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

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

"Grandmaster, please, this is the first practical steam engine we have built. It has been seven days since it was built to this day. We will use this steam engine for some time every day. Xiao Zhang, how long has this steam engine been working in the cumulative amount of time?"

As soon as Wang Dahui finished speaking, Xiao Zhang's researcher asked Xiao Zhang to flip through the notebook in his hand and spoke for a few seconds: "Grandmaster, our steam engine has been working for a total of thirteen hours and two quarters of hours."

Hearing Xiao Zhang's words, Fang Nan nodded slightly. He had to work for a total of thirteen hours and two quarters of a minute, which was barely considered a practical steam engine. The specific situation needs to be tested. The truly practical steam engine is obviously more than this working time, and it takes at least hundreds of hours to work stably.

However, Fang Nan did not demand too much. Compared with the steam engines that had failed to build before, this steam engine, which had been working for a total of thirteen hours and two quarters of a minute, has been 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 bit rough. The main body was a boiler that boiled water to produce steam. Below the boiler was used to create a fire. Above the boiler was a cylinder, and above the cylinder was a piston device.

Steam is generated from the boiler and enters the cylinder. Cold water is used to condense the steam in the cylinder and creates a vacuum. The air pressure on the other side of the piston pushes the piston, allowing the piston to work back and forth, thereby generating power and driving the water pump to pump water.

The structure of the steam engine is very simple, but it took Tang Bei and Wang Dahui project teams more than half a year to build such a practical steam engine. They spent a lot of time studying the principles of the steam engine, and more time was spent on building the steam engine.

The most important point in the steam engine is airtightness. Because of this alone, Wang Dachui and a group of craftsmen will hurt their heads. Once the airtightness is not good and the steam is gone, the steam engine will be a failure.

With the efforts of Wang Dachui and a number of craftsmen, the airtightness problem of the steam engine was finally solved. Although one failed product after another was created, the airtightness of the steam engine became better and better and the quality became higher and higher in the continuous failures. Finally, the barely practical steam engine in front of Fang Nan was created.

Wang Mu was also looking at the steam engine being worked on. Wang Mu knew some of the steam engine, including the principles of the steam engine. Wang Mu knew the teacher’s attention to the steam engine and could also feel the huge role of the steam engine. He had visited the Steam Engine Research Institute several times before. Now when he saw this practical steam engine, Wang Mu felt a lot of emotion.

Hydraulic machine tools can enable Foshan Arsenal to increase the output of firearms, which is the power of water. Moreover, hydraulic machine tools have great limitations. Hydraulic machine tools must stay next to the river, and the entire hydraulic machine tool is so large.

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

"This is a good thing." Wang Mu thought to himself.

Looking at the workmanship of the steam engine and the pumping of water, all kinds of praise were spoken from Fang Nan, which made some young people in the project team feel very embarrassed, and it also made the young craftsmen who are no longer young and can't speak.

They just created a machine, but they didn't expect to receive so much praise from the Grand Governor.

Of course, verbal praise is not enough, and there are physical rewards. Ordinary researchers reward ten acres of fertile land, thirty taels of silver, and the group leader and Wang Dachui and Tang Bei are rewarded with higher rewards.

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

Shaoqing, Fang Nan, Wang Mu, Tang Bei, Wang Dachui and others sat together.

"The steam engine you are building now has initially achieved practical value. Let's test the usage time limit. If it is qualified, you can build it in batches and send it to the mine for water pumping."

"I understand." Tang Bei said.

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

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

This new steam engine is more difficult to build and takes more time to study. I will often come here to help you."

Hearing Fang Nan's words, Wang Dachui said directly and affirmatively: "With the help of the Grand Commander, we will definitely be able to build a better steam engine."

Wang Dachui said this, and he thought so in his heart. Tang Bei was the same. The two of them trusted Fang Nan very much. This trust was used before. When they studied and built hydraulic machine tools and then steam engines, they would have even more trust.

Before seeing hydraulic machine tools and steam engines, no one could imagine that these machines were so magical. Almost everyone in the project team was immersed in studying 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 to give guidance every once in a while. Only with Fang Nan's guidance can the project team build a steam engine of practical value in more than half a year.
