During the rainy season, the sky is drizzling, and the fields are full of busy croppers, busy sowing seeds.

The experimental institute of Beijing Normal University Hall is also busy.

Entering the experimental courtyard, a long main verandah stretches out.

The main verandah is flanked by separate courtyards, which are connected by a short verandah to the main verandah for walking.

The construction of the experimental courtyard is so simple, there are no bananas and green bamboos, and there are no rockery ponds, only verandahs and independent courtyards.

At the end of the main verandah, Zhu Shun's exclusive independent courtyard is the largest independent courtyard in the experimental courtyard.

At the end of the main verandah is an arch, and when you walk into the arch, you will find a special experimental courtyard for the mountain chief, and the lintel is marked with a 0.

Courtyard 0 is surrounded by a circular wall of blue bricks and black tiles, with a layer of green bricks on the ground, and a steam engine is placed in the middle of the courtyard.

Zhu Shun stood next to the steam engine, thinking about how to improve the thermal efficiency of the first-generation steam engine, develop the second-generation steam engine as soon as possible, and realize industrial production.

After thinking about it for so long, Zhu Shun has found the key point.

The cylinders keep the heat while allowing the steam inside to be sufficiently cooled.

At this time, there was a sound of footsteps coming from the verandah outside the experimental courtyard, and listening to this sound, it should be the chief lecturer Wang Zheng.

Wang Zheng, who has nothing to do and likes to criticize everywhere, just walked out of the No. 2 experimental courtyard next to him and spurted the blood of the dog scolded by Song Shiyi.

He was complacent, he hadn't scolded Zhu Shun for a long time, and the last time he scolded Zhu Shun because of the crankshaft connecting rod system, he came here today to find a feeling.

Before I entered the experimental courtyard, I heard the roar of the steam engine movement, and puffs of smoke rose into the sky.

Wang Zheng glanced at it twice, it had been so long, and there was still no progress at all, and the problem of mouth damage came again: "How long has this been separated, the old man has come back from Xi'an Mansion, you kid should not do research." ”

"It's better to go home and farm ......... if you're still researching."

Before the loss was finished, Zhu Shun grabbed Wang Zheng: "Wait, what did you just say?" ”

Wang Zheng wanted to pull his sleeves out of his hand, worried that he would damage the satin collared shirt, so he could only let his black hand grasp it, and said angrily: "We might as well go home and farm." ”

Zhu Shun frowned and said, "It's not this sentence, the previous sentence." ”

Wang Zheng saw that he was endless, and he was even more angry, and this set of satin plate collared clothes cost a lot of silver: "This is all separated........."

Before they finished speaking, the two suddenly glanced at each other, and quickly turned their heads to the steam engine that was running 'click' and 'click'.

shouted in unison: "Yes, as long as the condensation steps of the steam engine are separated, that is, a condensing device is specially designed, this problem will be solved." ”

After the two of them finished chanting this sentence at the same time, they ran together to the main hall of the No. 0 independent courtyard, which was a study full of various design papyrus.

The two of them picked up a fine charcoal pen at the same time, wrote and scratched on a large piece of straw paper, and designed a separate condenser.

There was only one situation for the two to stop, quarreling.

Scolding the other party for the unreasonable place on the design straw paper, holding the design straw paper even if he eats at other times, and designing the detachable condenser in his sleep and dreams.

Half a month later.

A perfect design drawing of the separated condenser was presented in front of Zhu Shun Wang Zheng, and it was quickly sent to the Beiping Machinery Bureau on the other side of the river, so that several senior fitters worked overtime to build it.

Three days later, Chen Qu personally sent the modified steam engine over, and in order to prevent problems or need to be improved, he brought a set of tools and did not leave for the time being.

The split condenser is mainly composed of two cylinders, one is used to cool the steam and the other is an air pump.

The cooling cylinder and the air pump cylinder are installed on both sides of the steam engine.

Zhu Shun shoveled a pile of coal from the side and put it into the kiln, and as the egg container was heated, steam entered the piston cylinder from the intake valve.

The outer wall of the iron pipe of the inlet valve, after the modification, there is also an iron pipe connected to the condenser next to it, and there is a check valve at the top.

It didn't take long for Zhu Shun and the others to see steam spewing out from the check valve at the top, which indicated that the cylinder was already full of steam.

Zhu Shun walked over quickly and closed the inlet valve of the egg-shaped container in the voice of Wang Zheng scolding and scolding the scolding of your kid faster.

According to the design of Zhu Shun and Wang Zheng, the piston inside the iron cylinder of the air pump will rise, pumping out the air in the condensed iron cylinder, creating a vacuum.

In a vacuum condensing cylinder, the air pressure decreases, and steam enters the condensing cylinder from the piston cylinder to cool down according to the negative pressure principle of high air pressure to low air pressure.

The first generation of steam engines cooled steam by pouring water on the surface of a piston cylinder.

The steam inside condenses into water, and the temperature of the piston cylinder also decreases, so it is necessary to reheat the piston cylinder to ensure that the steam enters it as steam, rather than immediately condensing into water.

This wastes a lot of heat energy and reduces the efficiency of the steam engine.

Zhu Shun and Wang Zheng designed the separation condensing device, the steam is condensed in the condensing iron cylinder, and the piston cylinder is still hot, so the heat energy will not be wasted and the efficiency of the steam engine will be improved.

As the steam works in a continuous cycle, the steam engine spins faster and faster.

Five turns.

Ten turns.

Fifteen turns.

Sixteen turns!

Soon the limit of the first generation of steam engines was exceeded, sixteen revolutions per minute.

Zhu Shun looked at the Western chiming clock next to him and continued to count the speed of the steam engine.

Twenty turns.

Twenty-five turns.

Thirty turns.

As the speed of the steam engine became faster and faster, the sound became more and more urgent, and the louder the sound was caused, and Song Shihui, Song Shiyi, Jiao Miao, and Zhao Doumi, who heard the movement, all ran over.

Even Song Shihui put down the cigarette pouch, squatted in the corner, and held her breath as she looked at the steam engine that was speeding up.

With the acceleration of the steam engine, more and more people came, and it didn't take long for Zhang Tao and the talented students who got the news to come over one after another.

Forty turns.

Forty-five turns.

Forty-eight turns!

Forty-eight revolutions in one minute!

"It worked!"

"It worked!"

"It worked!"

The four disciples and the gifted students cheered, cheering for this exciting moment, and many geniuses even celebrated by playing crowns.

This is a way to celebrate only when you are promoted.

Zhu Shun and Wang Zheng glanced at each other, and they also laughed, they were going to try it a few more times, but they didn't expect it to succeed the first time.

The second disciple Song Shiyi ran over and hugged his teacher, and said happily: "Teacher, kill the pig?" ”

Zhu Shun nodded and said with a smile: "Kill pigs." ”

Killing pigs is to eat pig-killing dishes, only during the New Year, will eat this dish to celebrate, and today is even more to celebrate.

Celebrate the dawn of a new era.

Chongzhen five years, the rainy season.

The second-generation steam engine was successfully developed.

The age of steam begins today.

It's coming!
