Chapter 218 Steam
Guangzhou Yanhe Industrial Zone.

Zuo Xi, Feng Yutie and others gathered around a huge iron machine. A dozen craftsmen were operating the machine under the command of Chen Youwen.

Ever since Chen Xun went north, Chen Youwen was like a wild horse that had escaped the reins. He was completely free. At first, he pretended to study, but then he spent more and more time in the industrial area. Until now, he has basically stopped going to school. .

"Youwen, is there no problem this time?" Feng Yutie asked.

"As long as the piston ring you make is okay, it will definitely work this time." Chen Youwen replied.

"Then it must be no problem," Feng Yutie replied immediately, appearing very confident in his craftsmanship.

"Can this steam engine really output huge power? Can future ships be driven by it? No longer need sails?" Zuo Xi, an old shipwright, still couldn't believe it.

He has been paying attention to this steam engine for some time. From the beginning there was air leakage everywhere, and then the air leakage was almost blocked. However, because the seal was not in place, the output power was always very small.

Finally, Chen Xun's younger brother Chen Youwen got involved, using Chen Xun's notebook and using a sealing structure called a "piston ring" to make major changes to the steam engine.

Today is the first test run after the major renovation.

"It's definitely no problem. Brother has recorded in his notes that this kind of machine can be as powerful as tens of thousands of horses. Even if our machine doesn't have ten thousand horses, it still has a few horsepower." Chen Youwen was also excited. This is After studying for such a long time, it was the first time that he was truly fully involved in R&D work.

This sense of accomplishment from scratch is really enjoyable.

Because there is no rubber as mentioned in the notes, the cloth seal has never been up to standard. For a period of time, Chen Youwen was very frustrated and had some self-doubt. Fortunately, he finally got over his emotions and spent a lot of energy on the previous steam engine structure. Undertaken a major renovation.

Piston rings, to put it simply, rely on the pressure of steam to seal themselves. They are metal rings embedded in the grooves on the outer wall of the piston.

This kind of metal ring is a metal elastic ring with a large outward expansion deformation force, which is assembled into an annular groove (on the piston wall) corresponding to its cross section.

First, a groove is carved on the piston wall, and then the piston ring is embedded in the groove. The thickness of the piston ring arm is smaller than the inner diameter of the groove. Under natural conditions, the inner diameter is larger than the outer diameter of the piston ring.

The sealing is achieved by the close contact between the outward elastic force of the piston ring and the inner wall of the cylinder, as well as the close contact between the end face of the ring and the piston ring groove.

Steam enters the cylinder and pushes the cylinder outward. The groove on the outside of the cylinder drives the piston to break. There is close friction between the piston ring and the inner wall of the cylinder. This force forces the piston ring to be in close contact with one side of the groove to form a seal.

After the high-temperature steam is discharged from the exhaust hole at the top of the cylinder, the pressure inside the cylinder decreases. The flywheel outside the steam engine rotates according to inertia, driving the piston inward through the connecting rod. The friction forces the piston ring to be in close contact with the other side of the groove, and again Form a seal.

To give a vivid metaphor, it's like masturbating. The hand is the cylinder wall, the root is the piston, and the piston ring is the outermost ring of the crown.

(Will it be blocked? Worried!)
"Light the fire!" The stove under the water tank was lit, and several strong men were pulling the blower hard next to it.

The fire became more and more intense, hundreds of kilograms of water were quickly boiled, and steam gradually emerged from the gap at the top of the cylinder.

"Continue to add coal." Chen Youwen ordered.

The fire became more intense, and under the huge pressure, the water temperature in the water tank exceeded [-] degrees, heading towards [-] degrees.

Gradually, the impact of the steam exposed at the top of the cylinder became stronger and stronger, and finally, it made a whistling sound.

"Sizzling! Sizzling! Sizzling!"

The onlookers around him unconsciously stepped back, fearing that the water tank would suddenly explode.

Accompanied by the roaring sound, Chen Youwen ordered again: "Turn the flywheel!"

This is a very dangerous job. In order to prevent the operator from being injured by the flywheel, Chen Youwen designed a rotating device that is very easy to plug and unplug.Two strong men stepped forward and inserted the zigzag turning rod into the center of the flywheel, and then began to turn it hard.

"Be careful. If you feel that the resistance starts to decrease, withdraw immediately." Chen Youwen warned.

When cloth sealing was used before, someone was knocked away by the flywheel and directly injured.

lap!Two laps!Three laps!
Suddenly, the two people turning the flywheel pulled out the rotating rod with force at the same time.

"So fast?" Chen Youwen said in surprise. He thought it would take more than ten turns to make the steam engine output smoothly.

"It's already starting to lose strength," the strong man replied.

Sure enough, even though the force was applied only three times, the flywheel still did not stop and began to rotate on its own, faster and faster.

"It really doesn't leak!" Feng Yutie said in surprise.

I saw that the top of the cylinder would emit a stream of steam every one-third of the time, but it was absolutely sealed at other times. In Chen Youwen's previous design, this interval of ejection was normal.

"Succeeded! You succeeded!" Zuo Xi patted Chen Youwen on the shoulder excitedly.

"Yes! I succeeded!" Chen Youwen murmured, his eyes becoming moist. At this moment, he finally found his goal in life, which was to research all the advanced equipment and weapons in his elder brother's notebook.

As the flywheel spins faster and faster, the atmosphere at the scene becomes more and more enthusiastic, but there is still one last step to be considered a real success.

"Connect the transmission gear!" Chen Youwen ordered with a slightly choked tone.

"Yes!" The impatient craftsman immediately answered the order.

Move the push rod hard, the two gears mesh, and the large gear fixed on the flywheel starts to drive the other gear. The entire transmission mechanism immediately starts moving, and the power of the flywheel rotation is transmitted to the drilling machine next to it.

The drilling machine that originally needed to be driven by a waterwheel began to rotate rapidly under the speed regulation of a transmission mechanism composed of gears and belts.

"Success!!!"

"Ah! Ah!!!"….
Everyone in the factory went crazy with joy and started yelling.

"Youwen! You are a great contributor to our military government!" Feng Yutie came over and hugged Chen Youwen. Immediately afterwards, the surrounding craftsmen rushed over, lifted Chen Youwen and threw him into the sky.

"Ah!!" Chen Youwen shouted, smiling!

Feng Yutie and Zuo Xi, who were squeezed out of the crowd, looked at the group of energetic young people with relief on their faces.

"Director Zuo, you will be very busy next." Feng Yutie congratulated.

"Aren't you the same? With this kind of machine, the entire industrial production has been changed." Zuo Xi also sighed.

"Yes, it seems that I should be able to see the tens of thousands of stone steel battleships that the governor mentioned in my life. When the time comes, I will install hundreds of artillery pieces on it so that it can traverse the four seas." Feng Yutiechang thought. road.

"Okay, for you old guy, I have to build the steel battleship as soon as possible no matter what." Zuo Xi replied.
