Under the leadership of Lu Ping, Zheng Peng saw the first steamer built by the Changluo Headquarters in a secret shed.

Datang's first steamer is also the world's first steamer, or rather, it is just a prototype of a steamer.

The body of the steamer is a little large, from the point of view of the body shape, it is similar to Zheng Peng's design sketch, through the combustion boiler to produce high-pressure steamer to push the piston to move, in layman's terms, the heat energy is converted into mechanical energy that can be used, Zheng Peng saw that the gears and bearings were connected to the steamer, and sixteen wheels were installed on the bearings, obviously in preparation for testing and pushing the train.

Lu Ping lightly touched the steamer, and said with some feelings: "For this iron lump, several years of hard work are here, in order to create a boiler that is not easy to blast, no less than fifty have been built, and the craftsmen responsible for building the boiler say that they are boiler masters." ”

The steamer should be placed on the train, there is a constraint on the size, and there are also requirements for weight, when the arch is required to be powerful, the weight should be reduced as much as possible, so that the thickness of the boiler is limited, and the high-pressure steamer produced at the time of start-up has broken the boiler many times, and injured seven craftsmen before and after, one of which has been hit by high-speed fragments in the shoulder, and one hand is gone, and now the command can only do some logistics work, in order to find strong and lightweight iron, Lu Ping also went to Wangniudun to stay for nearly half a year, and worked with the craftsmen of ironmaking, and finally found the material that satisfied Lu Ping.

Zheng Peng nodded and ordered, "Let's take a look." ”

Hearing is false, seeing is believing, not witnessing it, Zheng Peng can't believe it.

Lu Ping responded, and then ordered his apprentice Zhuang San to start the steamer.

After about a quarter of an hour, the temperature of the shed increased significantly, and the steamer began to rumble to work, the high-pressure steamer pushed the pistons, which drove the halogen wheels and bearings, so that the eight wheels off the ground began to rotate rapidly.

Finally moved, Zheng Peng's eyes lit up, a subtle smile appeared on his mouth, and the cardinal who followed Zheng Peng, with a pair of good-looking big eyes, couldn't believe the scene in front of him.

It's just to burn some coal, boil some water, and that's ...... Can you move?

Zheng Peng noticed a detail, after starting the steaming machine, Lu Ping and Zhuang San subconsciously blocked in front of him, needless to say, he must have been afraid of an accident and hurt himself, so the master and apprentice took the initiative to stand in front and act as a meat shield.

Although it was just a subconscious protective action, Zheng Peng was secretly moved in his heart, indicating that he had been supported by the craftsman from the bottom of his heart.

Seeing that the steamer had been running for half an hour, Zheng Peng saw that there was no problem and signaled to shut down the steamer.

First, it is noisy, it is not convenient to ask questions, and secondly, the temperature in the shed is a little high, Zheng Peng saw that the cardinals on the side were already drenched in sweat, anyway, the effect had to be installed in the train to really reflect, no matter how much it was useless, it was a horse or a mule, and it was necessary to slip to know.

After the steamer stopped, Zheng Peng asked with interest: "Commander Lu, did you make a decompression device?" ”

"Young Master Wise" Lu Ping said with admiration: "There are often problems with the boiler in front, there are roughly two reasons, one is that the material is not strong enough, the other is that the fire is too violent, there are too many boilers inside, the boiler can not bear it, or the young master reminds that it is necessary to decompress at high pressure, and the small collection of more than ten craftsmen has made a few decompression gate valves, plus the new iron, tested for three months, there is no safety accident, and the small one dares to install it on the train." ”

"Yes, that's just what I mentioned,?? You guys solved it so quickly. Zheng Peng couldn't help but praise.

Lu Ping said modestly: "It's nothing, in fact, it's the same as automatic drainage, but automatic drainage is to make a floating board, when the water level reaches a certain height, the floating plate will push open the drain, so that the water is discharged from the pre-designed drain, the small one is too stupid, and I don't know how to correct it after failing so many times, fortunately, the young master reminded that this steaming machine, nine successful workers can be said to be the young master's, no, all of them are the young master's." ”

In fact, when he first heard Zheng Peng's idea, Lu Ping thought it was a fool's dream, but when Zheng Peng said the idea and structure one by one, the unattainable dream in his imagination became real again.

Most of the craftsmen are straight men, and the traces of patting sycophants are too obvious, not clever at all, Zheng Peng doesn't take it seriously, but continues to ask: "Transformation is a very important problem, and how to solve the sealing of boilers and pistons?" ”

Now there is no industrial rubber, sealing is a very critical issue, directly related to efficiency, just look at the speed of those wheels is very fast, the steamer still needs to be improved, but the efficiency is good.

When it came to the matter of craftsmanship, Lu Ping came to the spirit, patted the position of the boiler, and said excitedly: "Young master, the problem of sealing, the small and a group of craftsmen have repeatedly studied, and finally determined that two can be started in three aspects, one is to cast as a whole as much as possible and reduce the interface, so as to effectively prevent the chance of leakage; The second is to use a new process to finish the components. ”

Speaking of this, Lu Ping took down a square piece of iron from the cabinet on the side, signaled Zheng Peng to look at it, gently pushed it under his thumb, as if it was a trick, and then gently pressed it down in front of Zheng Peng, because it was polished very smooth and flat, it was almost impossible to see that it was separated, and he pressed the square iron pillar down by half, and then poured some water into the groove formed, and put it under Zheng Peng's nose, and said proudly:

"Young master, you see, the two are very tightly attached, and they can not leak for a day."

Ni Shu, Zheng Peng's eyes widened, isn't this the precision machining of later generations, it is high-tech, accurate to 0.01 mm technical work, it requires top precision machine tools to manufacture, the craftsmen of the Tang Dynasty actually did a similar job, although it can only be kept for one day without water seepage, but it is already very remarkable.

"Very good, I didn't expect your work to be so delicate, very good, very good." Speaking of the back, Zheng Peng couldn't help but say two very good in a row.

Being praised again and again by Zheng Peng, Lu Ping said a little embarrassed: "The young master has won the award, this workmanship is good, but the efficiency is extremely low, just such a simple thing, it has been done for a month and a half, the entire Changluo Command, including the craftsmen of the Three Treasures, only two old craftsmen who have been in the industry for more than 30 years can do it, the small ones have seen them polish, the front relies on the eyes, the back can only rely on the feel, and even use the tongue, and after the end, you have to find the best silk to try, and there can be no brushed wear after the wiping test, which is very time-consuming." ”

That is, in the Changluo Headquarters, the craftsman can calm down and pursue the ultimate, if he did this in other places, it is estimated that he would have been whipped or driven away by the master.

"It's worth it no matter how much time it takes, by the way, didn't you just say that there are three methods, and there is another way?"
