"The function of the steam engine is to convert the huge internal energy of the steam into mechanical energy, and then apply it to various production fields."

"The steam engine can directly trigger the first industrial revolution, so the invention and use of the steam engine is of epoch-making significance. The steam engine completely changed society, allowing human society to move from backwardness to civilization. ”

"Now, let your imagination run wild, and think of what the steam engine can be used for." Qin Yu said, "As a student, you must be diligent in thinking, thinking will make you smarter." ”

Qin Yu's teaching method has always been inspiring, allowing students to diverge their thinking.

"The steam engine can be used on a textile machine!" Zhu Fan said. I thought excitedly: My Ming textile industry is very developed in all parts of the Yangtze River, and it basically relies on manual spinning.

If you can put all the spinning machines, looms. Cotton spinning machines and looms are all changed to mechanical power to replace manual operation. It will greatly reduce manpower and improve production efficiency.

Then Daming's textile industry will immediately develop and grow.

There is no need to worry about not being able to sell too much production, and Daming's silk is an important export commodity.

In this way, the people of Jiangnan will also become rich.

Previously, the father and emperor implemented new policies in the three provinces in the southwest, such as apportioning the land into the mu, and the gentry as one errand and one grain payment, and the policy of Jiangnan remained unchanged, resulting in the development of the southwest surpassing that of Jiangnan. The people in Jiangnan complained a lot, and they kept immigrating to the southwest. Now that the mechanical power of the textile machine is about to appear, then the economy of the Jiangnan region will soon catch up.

Mr.'s favor first benefited the southwest, and now it benefits the south of the Yangtze River.

"You've got a very good idea!" However, Qin Yu didn't know what he was thinking, and praised, "There are also many ancient looms in our Lujia Village, and the women in the village often spin yarn and make their own clothes. ”

"If we can make a textile machine powered by steam, not only can we meet the clothing needs of the whole village, but the rest can also be sold in the surrounding villages to increase the income of the villagers."

"In other words, even if we don't have perfume, we can use the loom to make Lujia Village have enough food and clothing."

"Alright, you go on."

"The steam engine can be used on ships." Zhu Biaodao. I am also very excited: my current sea ship in Daming still relies on manpower to row oars and sails as power. When the fourth brother went on an expedition to the Wa Kingdom, a warship was equipped with seventy oarsmen.

Not only is it a waste of combat power, but it is also unpleasant.

If he can go on an expedition to the Wa Kingdom a little later, he will wait for the invention of the steam turbine...... Then the Ming warships must be rampant and invincible at sea.

Fourth brother, the expedition didn't catch up with the good time!

In addition, those treasure ships that go to sea to find gold deposits are also primitive power, and it takes too long to go back and forth.

"The steam engine can also be used in mining." Zhu Yingrao said.

"Sir, the steam engine can also be used to make perfumes." Lu Qingqian said, "In the perfume workshop in Lujia Village, it was originally distilled, and a lot of the vapor produced was wasted. ”

……

The students' speeches were very enthusiastic.

"Yes, you can all think enthusiastically, and every student deserves a lot of praise." Qin Yu said, "After talking about the steam engine, let's talk about it, the teacher wants to teach everyone how to make the steam turbine." ”

"The steam engine was the first to appear, a machine that used steam as power. Its structure includes cylinders, pistons, flywheels, governors, valves and seals, which are the basic elements that constitute modern machinery. ”

"The steam engine is very cumbersome to make, and it doesn't make a lot of use of steam."

"The steam turbine is the second generation of products that use steam as power."

"We can call it the Steam Engine 2.0"

"The steam turbine is more than ten times simpler in structure than the steam engine, and it is easier to implement in our village. Moreover, its utilization rate of steam is also ten times that of steam engines. ”

"The steam turbine is probably the highest level of steam-powered machines today. Even large aircraft carriers and thermal power stations outside are widely used. ”

"The following teacher will teach you the principle of work done by the steam turbine, and the realization method of converting internal energy into mechanical energy."

"And then together, we DIY a simple steam turbine out."

"Good!" The crowd listened and was excited.

……

"Yellow Label!"

"In!"

"Carry the blackboard out!"

"Yes, sir."

Zhu Biao rushed into the classroom with an arrow, carried the blackboard out, and put it on the shelf.

Qin Yu turned around and began to write on the blackboard, teaching while writing on the board: "The steam turbine is too simple, only two or three main components can be completed, let's make a simple one first, so that everyone can understand the principle of energy conversion." ”

"First, we needed to find a round box that would serve as the body of the turbine."

"Next, find another piece of iron to use as a fan blade, the fan blade is this shape......" said as he drew it on the blackboard.

"Finally, one tube is used to bring the vapor in, and the other is out. Not to brag about it, the teacher used to make a simple steam turbine when he was in elementary school, and the teacher used cans at that time. ”

"Isn't it easy?"

"Easy!" The crowd said.

"Is it easy to do?"

"Easy to do!" Again, the students said.

"Okay, now let's divide up and work together, the boy will find the round box, and the girl will make the fan blade, and we will make the steam turbine model together."

Half an hour later, the crowd had gathered all the materials.

Qin Yu led the students to start the experiment, boiling the kettle, connecting the conduit to the spout of the kettle to introduce the steam, and the high-temperature and high-pressure steam was sprayed onto the blade, making the blade rotate.

The internal energy of the vapor is converted into mechanical energy!

It's amazing!

Seeing this scene in front of them, the students were amazed.

Xiaoxiao has also been watching them operate from the side, because she is not Qin Yu's student, she can't participate in it. He looked at Qin Yu with loving eyes: This man is really great.

When he does things seriously, he is so charming.

Xiaoxiao can get the mercy of her husband, which is the happiest thing in Xiaoxiao's life.

"Now you've made a model of a steam turbine, and you've got the model turned." At this time, Qin Yu was still teaching seriously, "I understand the transformation principle of its work, and if you want to make a practical steam turbine, isn't it simple?" ”

"You only need to add gears to the blades, and then use the belt to drive the other gears."

"If you make the box bigger and add more blades to the rotor, you can generate a lot of power. The leaves should be small in the middle and large at the ends, ...... the two ends," he said, drawing on the blackboard.

After half a day of study, the students mastered all the production methods of steam turbines.
