Chapter 460

"How did you transform it?"

The change of Dengzhou made Xiao Ming feel very happy all the way. Now that the duplex steam engine has made progress, he is overjoyed. The industrial revolution is just around the corner. How can he not be excited? Now he is considering applying the steam engine to all walks of life.

As they went to Bowen college, Lin Wentao explained: "Your Highness, it's very simple. I connected two ports on the cylinder, one is the front air inlet and the other is the exhaust port. When the piston moves to the top, close the air inlet and open the exhaust port. Outside the exhaust port, the condenser is waiting for the hot steam, and the steam is instantly condensed Down, the steam is sucked out of the cylinder, and at this time, the cylinder is close to vacuum, the piston is also taken down. "

after a pause, he continued:" next, repeat the action just now to make the piston cycle. As long as the crank and connecting rod structure are connected, it can become the crankshaft movement. Moreover, I have tested that the efficiency of the duplex steam engine is five times that of the newcomer steam engine. "

" well, yes, Lin Wentao, your college of physics has really made a great contribution this time. In the future, Qingzhou will undergo earth shaking changes because of your contribution. I have to admit that the College of chemistry has really lost to you this time, ha ha ha "Xiao Ming laughed.

Lin Wentao then said, "however, your highness, the chamfering of this cylinder is too slow. The speed of producing duplex steam engines is very slow. Can you please" thank you, your highness. "A group of physics students said excitedly.

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

He went to Lin Wentao and said, "this glass steam engine was made by the glass workshop? "

" yes, your highness, glass is easier to shape, so we made this model just like a duplex steam engine. " Lin Wentao said: "then the equipment department restored the steam engine according to the model. "

" that's a good idea. All instruments developed in the future can use the method of making glass models first. " While speaking, Xiao Ming turns to the real duplex steam engine in front of him. It is a duplex steam engine made of pure steel and copper. It exudes an all metal texture, which is the characteristic of the iron and steel era.

With this steam engine alone, he has the capital to catch up with European civilization.

Now the first steam engine in Chongqing was officially born in Qingzhou. The following problem is the mass production of steam engine and its application in various industries.

In this era, there are only two kinds of steam engine motion, one is the linear motion through the connecting rod, the other is the rotary motion through the flywheel.

In order to speed up the application of steam engine in machine tools, Xiao Ming felt it was necessary to teach on site, so he called all the students and the craftsmen of the equipment department together and began to talk about the motion of connecting rod and crankshaft, and the use of flywheel.

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

after a pause, Xiao Ming continued:" the connecting rod body is a long rod, and it has a large force in the work, so in order to prevent bending deformation, you should use I-section in the production of the rod body. This is because the strength of I-section is high enough, followed by the flywheel, which is a disc structure. Through this structure, the steam engine can make the machine rotate "

while Xiao Ming was talking, the pictures began to appear in the minds of the students and the instrument engineers. The connecting rod, crankshaft, flywheel and other structures of the steam engine flashed one by one. At the same time, the pictures of the steam engine driving these components were also very clear.

Based on Qingzhou's industrial base, the steel needed for steam engine is not a problem at all. Naturally, the quality of connecting rod, crankshaft and flywheel is not a problem, so he only needs to tell Lin Wentao and Zhang Liu how to use these components and how to make them? They have their own way.

After some explanation, people have a preliminary understanding of the use of steam engine. Many of them just understand the need to develop steam engine, but many people don't understand the use of steam engine. Now they finally understand the importance of steam engine.

”Your highness, we understand. When we get back, we'll make flywheels. "Zhang Liu said that Xiao Ming made it very clear that as long as a certain torque is applied to the flywheel through the connecting rod and crankshaft, the flywheel will rotate.
