Steel Dynasty - Chapter 459

[Chapter 459 Compound Steam Engine]

“How did you transform it?”

The changes in Dengzhou made Xiao Ming very happy along the way. Now that there is progress in the compound steam engine, he is overjoyed. The industrial revolution is right in front of him. How can he not be excited? Now He was already thinking about applying steam engines to various industries.

As the two walked towards Bowen College, Lin Wentao explained: “Your Highness, it’s actually very simple. I connected two ports on the cylinder, one is the air intake port in the front and the other is the exhaust port. When the piston moves to the top At the end, close the air inlet and open the exhaust port. Waiting for the hot water vapor outside the exhaust port is the condenser. The outgoing water vapor is instantly condensed, and the water vapor is sucked out of the cylinder. At this time, the cylinder instantly When it was close to the vacuum, the piston was brought down. “

After a pause, he continued: “Then repeat the action just now to make the piston reciprocate. As long as the crank and connecting rod structure are connected, it can become a crankshaft motion. , and I tested it and found that the efficiency of the compound steam engine is five times that of the Newcomen steam engine. “

“Well, yes, Lin Wentao, your School of Physics has really made a great contribution this time. Qingzhou will be famous for your contribution in the future. Earth-shaking changes, I have to admit that the School of Chemistry really lost to you this time, hahaha…” Xiao Ming laughed.

Lin Wentao said at this time: “But Your Highness, the bore cutting of this cylinder is too slow. The production speed of the compound steam engine is very slow. Can the first steam engine be used in the bore cutting of the lathe, so that it can be made?” The working efficiency of the lathe has increased many times. After all, the lathe in the water conservancy workshop is greatly affected by the water flow, and the efficiency is also very low.

“Of course, your School of Physics does not need to do anything else. Now you and the Equipment Department work together. Once the steam engine production line is built, whether it’s money or people, I’ll sell the palace and raise it for you. “Xiao Ming made bold words.

What his fiefdom lacks most now is population, and the development of steam engines will greatly alleviate this problem.

“Thank you, Your Highness. “After receiving Xiao Ming’s promise, Lin Wentao was so happy that he couldn’t help but smile.

The two of them talked all the way to Bowen College. At this time, there were two steam engines in the physics laboratory of Bowen College. One steam engine was a Newcomen steam engine, and the other was a Newcomen steam engine. It is a compound steam engine. Zhang Liu and other craftsmen are observing the movement of the steam engine in the laboratory. One of the two steam engines is moving up and down, and the other is moving on the crankshaft.

“Your Highness, Lin Wentao is a good guy. We just helped him put Newcomen.” The steam engine was produced, and they asked us to reassemble a steam engine. “Zhang Liu said with a smile: “Now we are studying how to combine the boring machine and the steam engine. “

Xiao Ming also saw the steam engine in the laboratory at this time. Seeing these two real steam engines, he suddenly felt that he had arrived in England during the Industrial Revolution.

Lin Wentao said at this time; “Your Highness, this steam engine is not just mine. The credit belongs to all the students of the School of Physics. We studied and discussed together and solved the problems before developing the compound steam engine. “

It seems that everyone is making progress. Well, this is what I want to see.” “Xiao Ming looked around at the students from the School of Physics and said. “It seems that I have to award you a collective medal of honor.

“Thank you, Your Highness.

“

“A group of students from the School of Physics said excitedly.

While everyone was laughing, Xiao Ming suddenly saw a small model of a steam engine made of glass placed on the middle podium of the laboratory. Under the model was an alcohol lamp.

He walked over He said to Lin Wentao: “Did you ask the glass workshop to make this glass steam engine? “

“Yes, Your Highness, glass is easier to shape, so we made this model based on the appearance of a compound steam engine. “Lin Wentao said: “Then the Equipment Department restored the steam engine according to the appearance of this model. “

“This is a good idea. All devices developed in the future can use the method of first making a glass model. “Xiao Ming said as he turned to the real compound steam engine in front of him. This is a compound steam engine made purely of steel and copper. It exudes an all-metal texture. This is the characteristic of the steel age.

Just with this He already had the capital to catch up with European civilization.

Now that the first steam engine in Dayu was officially born in Qingzhou, the next problem is the mass production of steam engines and their application in various industries.

There are only two types of steam engines in this era. , one is through the linear motion of the connecting rod, and the other is through the rotational motion of the flywheel.

In order to speed up the use of steam engines on machine tools, Xiao Ming felt that it was necessary to conduct an on-site teaching, so he invited all students and craftsmen from the equipment department. Let’s get together and start talking about connecting rod motion and crankshaft motion, and the use of flywheels.

“The connecting rod body is composed of three parts. The part connected to the piston pin is called the small end of the connecting rod, the part connected to the crankshaft is called the big end of the connecting rod, and the connecting small end. The rod part with the big end is called the connecting rod body. The small end of the connecting rod is mostly a thin-walled annular structure. In order to reduce the wear with the piston pin, a thin-walled bronze bushing is pressed into the small head hole. Drill or mill grooves in the small head and bushing to allow splashed oil to enter the mating surface of the lubricating bushing and piston pin. “

After a pause, Xiao Ming continued: “The connecting rod shaft is a long rod and is subject to large forces during work. Therefore, in order to prevent bending and deformation, you must use an I-shaped section when producing the shaft. This is because The strength of the I-shaped section is high enough, followed by the flywheel, which is a disc structure. Through this structure, the steam engine can rotate the machine…”

While Xiao Ming was talking, the scene began to show the students and the craftsmen of the equipment department. In his mind, the connecting rod, crankshaft, flywheel and other structures of the steam engine flashed one by one. At the same time, the picture of the steam engine driving these components was also very clear.

With Qingzhou’s current industrial base, the steel required for the steam engine is not a problem at all. This connecting rod. The quality of the crankshaft and flywheel is naturally not a problem, so he only needs to tell Lin Wentao and Zhang Liu how to make these components.

After some explanation, everyone has a preliminary understanding of the use of steam engines. Many people in China just understand that they need to develop steam engines, but many people don’t understand the use of steam engines. Now they finally understand the importance of steam engines.

“Your Highness, we understand. We will produce flywheels after we go back.” “Zhang Liu said, and Xiao Ming made it very clear. As long as a certain torque is applied to the flywheel through the connecting rod and crankshaft, the flywheel will rotate.
