Su He stood next to the window and watched the operation of the steam engine after replacing the sealing gasket.

The steam engine runs smoothly, and the piston reciprocates steadily, driving the flywheel to rotate rapidly.

Du Kangjie said excitedly: "Your Highness King Qin, the effect of the pure copper sealing gasket is really great.

It's extremely difficult to process, but it's worth the money.

Pure copper gaskets are polished bit by bit by craftsmen after rough processing by machines.

Now our team only has three craftsmen with the ability to process pure copper gaskets."

Su He looked at Du Kangjie and explained: "You should cooperate with other personnel to simplify the processing of pure copper gaskets as much as possible.

Improvements can be made in these two directions by designing machines for processing pure copper gaskets and improving the structure of the gaskets.

Only top craftsmen can process pure copper gaskets.

This is not conducive to the popularization of steam engines. It is best to reduce the processing requirements to level 6 or 7 craftsmen, who can also complete the processing of pure copper gaskets."

Du Kangjie nodded and said: "Your Highness, King Qin, I will try my best to complete it."

Su He knocked on the window again and told Lu Jin inside the room: "The steam engine has been running smoothly for a day.

Add a load to it and test the power of the steam engine.

Let’s see if the steam engine can replace the waterwheel.”

The purpose of developing steam engines was to replace waterwheels and become the power source for factories.

Now the steam engine runs very stably with no load, and if it runs with load, it is still stable.

Steam engines can be mass-produced, transported to various factories, and become the power of the factories.

The flow of the Han River has dropped significantly this year, and many factories along the coast have been forced to close their doors.

The machines in the factory are all designed to adapt to hydraulic power. Without power, the factory cannot operate at all.

Once the steam engine can be used, these factories will start to operate one after another.

After Lu Jin heard Su He's instructions, he first adjusted the steam valve to slow down the speed of the steam engine's flywheel.

Lu Jin directed the workers to connect the steam engine flywheel to a large power shaft through a belt.

In major factories, waterwheels and machines are connected through power shafts.

The current layout of the factory is that the factory has a power shaft passing through the factory.

It is connected to the factory machinery through belts or chains.

If a steam engine wants to replace a waterwheel, it only needs to connect the steam engine flywheel to the power shaft.

There is no need to change the layout of other machines, only the connection between the steam engine and the power shaft needs to be changed.

Factory replacement of power is very convenient and quick.

Lu Jin saw the workers and made a completion gesture.

He readjusted the steam valve and returned the steam engine to full power.

The flywheel of the steam engine drives the power shaft to rotate at high speed.

The other end of the power shaft is connected to a forging hammer.

The forging hammer rose, the huge hammer was lifted to a high place, the gears suddenly released, and the hammer dived down at high speed.

The huge hammer directly hits the steel placed on the platform.

Through continuous forging, the properties of steel are changed.

This is where some parts of the steam engine are made.

Su He watched the forging hammer running smoothly and said happily: "The power of the steam engine is very strong, far exceeding the power that the water wheel can provide.

The power provided by the waterwheel cannot even lift the current model of forging hammer.

The parts before the steam engine were still knocked out bit by bit by craftsmen.

It can now drive this forging hammer and provide power for any current factory."

Su He announced happily: "The steam engine project was successful.

Our factories will no longer be constrained by water power."

Everyone cheered enthusiastically when they heard Su He's words.

The steam engine took a year to develop and finally succeeded.

Suhe steam engine load operation conditions.

He also discussed with everyone the application of steam engines in industry.

The sky had turned completely dark, and Su He was taking a deep breath.

He saw that the steam engine was running smoothly without any problems.

Su He took the lead in applauding. The steam engine could reach this level and could be put into factories.

Even if it has some minor problems, Suhe is ready to put the steam engine into the factory.

Researchers from the Institute of Mechanical Engineering of the Academy of Sciences solve steam engine problems during use.

A factory must prepare multiple steam engines as power.

If a steam engine is damaged, it will not affect the normal production of the factory, but the production efficiency will become lower.

If the factory has low production efficiency and is completely shut down, you must choose the factory with low production efficiency.

This steam engine brought surprise to Suhe.

It ran for so long and no obvious problems were discovered.

"This model of steam engine can be officially mass-produced.

Mass-produce a batch of steam engines as soon as possible, transport them to important factories, and install and debug the steam engines.

Find problems during use and continue to improve the steam engine."

Su He issued the order, and the entire Qin Prince's Mansion began to operate efficiently.

The Institute of Mechanical Engineering of the Academy of Sciences transferred a large number of personnel to establish a steam power company to manufacture steam engines and began to manufacture steam engines for use in factories.

…………………………

Maoxiang was listening to the class and was distracted from time to time, looking out the window at the strange sight.

He poked Li Yan, who was sitting next to him and was listening carefully to the lecture.

"Brother Li, what do you think the big chimneys on the other side of the river are for?

Coke and steel mills already have large chimneys, so it is not surprising that they increase production capacity and build chimneys.

Why do weaving factories build big chimneys?”

Maoxiang was very curious. During this period, urgent construction started in the industrial zone.

Many workers used reinforced concrete, a precious material, to build large chimneys more than ten meters high.

Some factories build more than one large chimney.

Over the past few days, these large chimneys have begun to emit billowing black smoke.

Now in the sky over the southern industrial area, dozens of black smoke pillars are rising into the sky, and dark clouds are billowing across the sky.

Li Yan shook his head and said: "I don't know, what are these big chimneys used for?

You also listened carefully to the lectures. Last time you went to the Ministry of Criminal Justice for an internship, you got a zero score. That was so embarrassing.

This is a class for the Minister of Industry. Let's not make any noise and disturb his class.

The better your internship performance, the better the official position you will be assigned.

The final exams are about to start in the spring, why are you not in a hurry?"

Zhang Dezhi was giving a lecture on the stage. He saw someone whispering behind him and he motioned for them to be quiet many times, but neither of them stopped.

Zhang Dezhi couldn't help it and said in a stern tone: "Li Yan, if Maoxiang doesn't listen carefully to the class, one class point will be deducted."

These two students have always been the thorns in the class and are not stable at all.

His level is limited and his lectures are a bit boring and not as lively as others' lectures.

These are new scholars who may rise up in the future, and other teachers should save their face.

Zhang Dezhi does not need to do this. He will only be the Minister of the Ministry of Industry in this life and has no room for improvement.

His son was the commander of the strongest artillery division under King Qin.

My son showed great success in the war not long ago and has been granted the title of Duke and Duke.

His eldest disciple Wei Shiming is now the governor of Hetao and a senior official guarding one side.

The course he taught was also very important, the impact of industry on the country.

This is a work he wrote with great painstaking efforts after consulting His Highness the King of Qin and many other people, combined with his own experience.

If they don't learn this lesson well, if they really become officials in this big environment, they will definitely fall behind others.

Zhang Dezhi completed this class with great interest.
