Destiny Only Han

Chapter 691 Liu Ying: I'm talking about chicken and duck, right?
"Who is calling me behind my back?"

Liu Ying pinched the bridge of her nose, restrained the urge to continue sneezing, her face full of bewilderment, after all, he thought he was a good person and didn't offend many people...

But Zhang Buyi disagreed. He counted silently with his fingers, and found that both hands were not enough. He said with a smile, "Maybe he caught a cold... Well, after all, Shangjun is a bitterly cold place, although it doesn't snow now. But the snow on both sides of the road has not melted..."

"That makes sense." Liu Ying nodded in agreement.

What they are doing now is the inspection work before the departure of the train. The clothes they are wearing are cotton jackets and sheepskin vests. They are not wearing thick fur cloaks as usual. They are holding a hand stove in their arms. It is definitely cold. of.

Well, there is actually nothing to check, the main thing is excitement...

After all, the train will leave from Shangjun tomorrow. Not only Liu Ying and Zhang Buyi, but also many farmers or herdsmen from Shangjun and Jiuyuan counties who are at home in Maodong also rushed over and camped in the grassland near the parking lot. superior.

As a result, small vendors who sensed business opportunities came in droves. These days, cattle and sheep neighing and human noise can be seen everywhere. The county magistrate of Fushi County ordered people to build fences around the surrounding area overnight, erect city flags, and were soft on charging booth fees...

And around Shangjun, such as Jiuyuan County, Yunzhong County and other places, there are many Hu people who have been Sinicized, and Han people who have been Huhua, so they dance around fire pits, sing songs with wine, or wrestle hard all day long. Another New Year's look...

However, more people who eat melons still gather around the parking lot, poking their fingers with pockmarks, chatting from all over the world to their parents...

"I don't believe it." Zhang Buyi was categorical.

Zhang Buyi was stunned for a moment, held up his brush and said helplessly: "In such a cold day, the paint is frozen, so it can't be painted... By the way, why does your paint look like this? How come I haven't seen it before?"

"It's easy to learn." Liu Ying pointed to the wheels under the train:
"You see, there are three driving wheels on each side of the front of the car, and a rocker is installed on the side of the third wheel, which is pushed by a steam piston. The rocker drives the crank to make the wheels move. Turn, and an eccentric crank is installed on the head of the crank, and when the wheel turns, it drives the eccentric rod above to swing back and forth, which in turn drives the crescent plate to swing back and forth on the bracket."

Liu Ying swallowed her saliva in disappointment, but continued to walk forward, tapping and tapping: "I'll watch it again..."

Zhang Buyi touched it and put it quietly on the rails, like a silent giant train, and nodded slightly.

"When the crescent plate swings, push and pull the radius rod to move back and forth, push the combined rod to move the valve in the air chamber, the other end of the combined rod is connected to the combined rod, and the combined rod is connected to the crosshead on the slide, and the crosshead is driven by the cylinder. The steam piston pushes it...hey, it's this thing, one end of it is connected to the cylinder piston rod, and the other end provides power for the rocker..."

Zhang Buyi shook his head:
"I understand that it is difficult to train engineers, but what is so difficult about dispatching? It is nothing more than letting trains enter and leave the station in an orderly manner. Those Chang'an government officials on the cross street in Chang'an City who direct the passage of horse-drawn carriages are not just doing this. From there Wouldn’t it be enough to call a few over?”

Zhang Buyi lamented: "It's been eight times, why don't you still watch it? Just forgive me...I'm cold."

You are a fragrance smeller... Liu Ying said with a smile: "That's all right, come back and get some asphalt paint to study, and I will be your investor if you get results."

Liu Ying curled her lips: "You are Mr. Liuwai, a carnivorous person. It is normal that you have never seen such working people's things."

After a while, Liu Ying couldn't bear it anymore, pointed at the locomotive and said: "See clearly, this kind of big guy can not only run forward, but also run backward, and it is automatic, stepless speed change!"

He had seen the scene of the train running before, puffing out white smoke, rumbling towards it, full of oppressive feeling, people couldn't help but want to worship!

"Okay, when you pass the fork leading to the wharf, it's okay for you to drive for a day!" Liu Ying smiled all over her face, but raised her fingers and said, "But when I get to Chang'an City, I will drive it in person. I have always done my part to be in the limelight!"

"It's easy to say, but it's hard to do." Liu Ying picked up a stick and gesticulated on the ground twice, then raised her head and asked, "Look, it's very simple to have two railways going back and forth, but what about a crossroad? What about crossroads? Or even four or five trains in different directions entering and leaving the station at the same time, leading to different places at almost the same time?"

Zhang Buyi was stunned for a while, pointed to a few handles in the cab, and made a conclusion: "In other words, I only need to push these few things to make such a big iron bump run steadily." ?”

"Then, can I have a meeting then? Well, just for a while!" Zhang Buyi looked at Liu Ying, with some pleading in his eyes.

"You only need to control the radius rod to move up and down, and you can control the train to move forward and backward, and the speed of the train can also be adjusted according to the difference in the blocking ratio, without additional components. This is what I call a continuously variable speed change!"

Turtle... Liu Ying glanced at him contemptuously: "What's wrong with running fourteen trains on two rails? For such a long distance, let alone fourteen locomotives, even 140 are more than enough!"

Liu Ying sneered: "Now you know where all the initial investment has been spent? It is true that building rails, making sleepers, and assembling locomotives is expensive, but this is all obvious. As long as the investment is made, there will be output."

Well, he used to have this kind of problem. After repeated verification of a certain thing, he began to doubt himself, and he couldn't fix himself...

"Yes, there is only one Chang'an-Kowloon Railway now, and there are only a few branch lines leading to coal mines, wharves, and Yanchi, but I can guarantee that at most three years, at least five more railways will start construction one after another, leading from Chang'an City to different cities. The place!"

Hearing Liu Ying's words, Zhang Buji leaned on the paint bucket and smelled it, and nodded, "It really smells good...it has a very strange smell. If it can be extracted and made into perfume, it should sell well!"

"You see, when moving forward, the handle of the return motor is pushed forward, the radius rod moves down, the stroke of the air chamber valve increases, and the steam pushes the wheels forward... When it is necessary to reverse the car, the handle of the return motor is pulled back, and the radius rod moves over the midpoint to the upper Dead center, the stroke of the air chamber valve first decreases and then increases again, and the steam reverses and pushes the wheel backwards."

"It's cold and you won't wear more?" Liu Ying handed over a brush made of pig bristles: "It won't be cold if you do some work. You can see if the paint on the carriage is not evenly painted. You can paint it again... "

Zhang Buyi nodded perfunctorily, but looked at the locomotive covered with grass curtains in the distance and asked: "There are only two rails in total, and you built fourteen locomotives. Are you going to use them up? It's useless to spend all the money." No wonder your bonds can't be sold!"

Asphalt paint is extracted from coal tar, and has a good anti-corrosion effect, especially for large ships that are sailing. Because of the color problem, large ships painted with asphalt paint are also called 'black ships', which is why the book began to be reformed. The black ship of the black ship incident.

With Zhang Buyi's face full of bewilderment, Liu Ying enthusiastically pulled him onto the front of the car, and continued:

"The most difficult thing is actually to cultivate suitable talents, who understand mechanical principles and how to make the locomotive run smoothly. What is important is dispatchers, especially dispatchers. With them, the entire railway can run at high speed, so that I can use it with profit. Pay off the interest on the bond and then take in more investment..."

So Liu Ying became Alexander...

I understand, I understand... Zhang Buyi nodded lightly, and another bearded man who likes to show off appeared in his mind, with a somewhat flattered look on his face: "It's just right, I'm idle now anyway, you come Teach me how to drive a train! Well, is it hard to learn?"

Zhang Buyi, who was following Liu Ying, looked impatient: "Let's go back, the yellow mutton that was frozen last night has begun to thaw slightly, and it's just time to slice the mutton...the cooked mutton is dipped in leek sauce The dipping sauce mixed with sesame sauce, fermented bean curd, just one word, beautiful!"

"If such iron bumps collide, have you ever thought about the serious consequences?"

"Nonsense, it has nothing to do with who I am! Even if my father came here, he wouldn't know your kind of lacquer. How dare you call him a meat eater?" Zhang Buyi threw away the brush and put his hands on his hips, but he looked a bit bitch. Chirp...

However, in today's Han Dynasty, the Japanese are already in a state of genocide, and the fleet of the Han Dynasty is painted with black asphalt paint. The "black ship incident" will most likely become the fuse for the American or European reforms...

"No argument." Liu Ying turned her face aside.

As for coal tar, it is a subsidiary product of coke refining. In the era when coal and iron workshops are blooming everywhere, how much coal tar is needed...

Zhang Buyi was confused: "What the hell, automatic... gear? Continuously variable speed? What is this talking about?"

"No nonsense! Although the teacher is old, he climbed over the wall and jumped and ran faster than me. I complained about him, is it too long?" Liu Ying smiled and recalled that she was always "sick" Zhang Liang, who was at home, shook his head and explained:
"This is not varnish made from lacquer trees, but asphalt varnish. It smells peculiar. Those who like it can smell it for a day, and those who don't like it will avoid it. But it's easy to use. Anyway, it's better than our big lacquer. The waterproof effect is better, and the important thing is that it is cheap and sticky, and does not need to be reapplied over and over again!"

Liu Ying froze for a moment, then nodded in agreement.

Zhang Buyi suddenly became arrogant: "I said a lot of scumbags, I didn't expect it to be so simple! If you said otherwise, it would be over, and I was almost confused..."

Liu Ying is full of helplessness. The structure of the steam train is actually very simple. The difficulty lies in knowing why it is done. Behind the simple structure is the brains of countless engineers...

Therefore, liberal arts students are really annoying!
