Chapter 457: Compound steam engine

One second of genius remembers, to provide you with wonderful novel reading.
"How did you make it?"
The changes in Dengzhou made Xiao Ming feel very happy along the way. Now that the compound 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 the two of them went to Bowen Academy, Lin Wentao explained: "Your Majesty, it's actually very simple. I connected two ports to the cylinder, one is the front intake port and the other is the exhaust port. When the piston moves to the top At the end, close the intake port and open the exhaust port. The condenser is waiting for hot water vapor outside the exhaust port. The water vapor out is instantly condensed, and the water vapor is sucked out of the cylinder. Close to the vacuum, the piston is carried 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 crankshaft motion. And I tested it. The efficiency of the compound steam engine is Five times the Newcomen steam engine."
"Well, yes, Lin Wentao, this time your School of Physics really made a great contribution. Qingzhou will change drastically in the future because of your contributions. I have to admit that this time the School of Chemistry really lost to you. , Ha ha ha..." Xiao Ming laughed. 【】
Lin Wentao said at this time: "But your Highness, the bore cutting of this cylinder is really 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 The work efficiency of the lathe is increased many times, after all, the lathe of the hydraulic workshop is greatly affected by the water flow, and the efficiency is also very low.
"Of course, now your Physics College doesn't need to do anything else. Now you and the Department of Apparatus are working together to build a steam engine production line. Whether it is money or people, this king will sell the palace and collect it for you." Xiao Mingkou made bold words.
What he lacks most in his fiefdom now is population, and the development of a steam engine will greatly alleviate this problem.
"Thank you, Your Highness." Lin Wentao happily closed his mouth from ear to ear after receiving Xiao Ming's promise.
They 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 compound steam engine. Zhang Liu and other craftsmen were observing the steam engine in the laboratory. The two steam engines are moving up and down, and the other is cranking.
"His Royal Highness, Lin Wentao is a good boy. We just helped him produce the Newcomen steam engine, and they let us reassemble a steam engine." Zhang Liu said with a smile: "Now we are studying how to combine a boring machine with a steam engine. ."
At this time, Xiao Ming also saw the steam engine in the laboratory. Seeing these two real steam engines, he suddenly felt that he had come to England during the Industrial Revolution.
Lin Wentao said at this time: "His Royal Highness, this time the steam engine is not only my credit, but the whole credit of the students in the School of Physics. We researched and discussed together and solved the problem before we developed the compound steam engine."
"It seems that everyone is making progress, um, this is what the king wants to see." Xiao Ming said, looking around the students in the physics college. "It seems that this king has to give you a collective honor medal."
"His Royal Highness." A group of students from the School of Physics said excitedly.
While everyone was laughing, Xiao Ming suddenly saw a small glass model of a steam engine placed on the middle podium of the laboratory. Under the model was an alcohol lamp.
He walked over and said to Lin Wentao: "You let the glass workshop make this glass steam engine?"
"Yes, your majesty, glass is easier to shape, so we made this model according to the appearance of a double steam engine." Lin Wentao said: "Then the equipment department restored the steam engine according to this model."
"This is a good idea. All the equipment developed in the future can use the method of making glass models first." Xiao Ming said, turning to the real compound steam engine in front of him. This is a compound steam engine made purely of steel and copper, which radiates all over the body. With an all-metal texture, this is the characteristic of the steel age.
Only with this steam engine he already has the capital to catch up with European civilization.
Now the first steam engine of Dayu State was officially born in Qingzhou, the following question is the mass production of steam engine and its application in various industries.
There are only two types of steam engine movements in this era, one is linear movement through the connecting rod, and the other is rotational movement through a flywheel.
In order to speed up the use of the steam engine on the machine tool, Xiao Ming felt that it was necessary to give a teaching on site, so he gathered all the trainees and the craftsmen of the equipment department and began to talk about connecting rod motion and crankshaft motion, 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 connecting rod end, the part connected with the crankshaft is called the connecting rod big end, and the rod connecting the small end and the big end is called the connecting rod shaft. Mostly thin-walled circular ring structure, in order to reduce the wear between the piston pin, a thin-walled bronze bushing is pressed into the small head hole. Drilling or milling grooves on the small head and bushing to allow splashing oil to enter Lubricate the mating surface of the bushing and the piston pin."
After a pause, Xiao Ming continued: "The connecting rod shaft is a long member~EbookFREE.me~ It also bears a lot of force during work, so in order to prevent bending deformation, you should use a 1-shaped shaft in the production. Section, this is because the strength of the 1-shaped section is high enough, followed by the flywheel, which is a disc structure through which the steam engine can rotate the machine..."
While Xiao Ming was speaking, the pictures began to appear in the minds of the students and the equipment masters. The connecting rods, crankshafts, and flywheels 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.
With the current industrial base of Qingzhou, the steel required for steam engines is not a problem at all. The quality of the connecting rod, crankshaft, and flywheel is naturally 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 explanations, everyone has a preliminary understanding of the use of steam engines. Many of them just understand the development of steam engines, but many people do not understand the use of steam engines. Now they finally understand the importance of steam engines.
"His Royal Highness, we understand. After we return, we will produce flywheels." Zhang Liu said, Xiao Ming said very clearly, as long as a certain torque is applied to the flywheel through the connecting rod and the crankshaft, the flywheel will rotate.
