"Your Excellency...... My lord! ”

This time, the little bell was particularly excited, and with the long rabbit-like legs, he ran quickly from the machinery factory into the county government and said excitedly: "Steam engine...... Steam engine ......"

Wang Yan jumped up in fright: "What's the matter, did it explode?" ”

The little bell thought about it, it was indeed very moving, as if it had exploded, so he nodded and said, "It's exploded." ”

As soon as he heard this, he took pills, and his eyes turned black and he wanted to fall to the ground.

The little bell said excitedly: "That big guy didn't listen when he exploded, he jumped all the time, he couldn't hold it down, and he was still exploding?" ”

Hey.

Wang Yan heard that it seemed to be a success, so he didn't pump the back of her head, and immediately took someone to the machinery factory.

After I arrived, just outside the workshop, I felt a rumbling tremor on the ground. A large group of technicians were surrounding the start-up machine, which was unaware of its appearance, while the big crane was observing the movement and vibration of the machine.

This thing is obviously immature, and there are still too many problems. It is like a person with a heart problem, and the strength of the vibration is different. There are still too many things that are missing, but they are indeed created by them for public relations.

Every time the vibration is large, given that this is something similar to a monster, the technical workers who can make it by themselves are scattered and fled in shock, but Lao Luo Dad is left looking at this strange thing in a circle.

"The irregular vibration with different strengths proves that the craftsmanship and precision are not up to par in many places, and there are some conflicts between internal machinery." Wang Yan was very bold and approached Lao Luo's father and said.

These can't be demanding, and being able to do this step is already faster than Wang Yan expected. Theoretically, the materials are poor, for example, without rubber, some shock absorption and sealing measures cannot be achieved. However, under the requirements of Stalin's and Hitler's style, they were made by the correction of manual craftsmanship and the great sacrifice of efficiency.

Lao Luo's father personally designed and manufactured things, of course he understood what Wang Yan said, nodded with a deflated look: "What my lord said is that the design is indeed designed according to the ideas and requirements you provided, but there are conflicts under the existing process, and it has been tried too many times. As a result, only a small number of lowly and a limited number of master craftsmen forged it by hand, and then polished it by hand fine processing, but in that case, the complete geometry could not be completely guaranteed. We have tried our best, and it seems that the error in every place has tried our best to minimize it, but after the final assembly and test machine, there are too many links and too many parts, resulting in the cumulative error exceeding the acceptable range. Thereupon...... That's what you see. ”

What Lao Luo Dad said, Wang Yan can fully imagine even if he is not an engineering student, if it is just a simple two gears occlusion, then the fault tolerance rate will be very high, even if the error between a group of gears is half a millimeter, and there are some flaws in the geometry of the circle, it can also operate, which is nothing more than a reduction in efficiency and increased wear.

But even if the steam engine is the simplest machine, it is also a lot of parts connected and bitten after running, with too many links, each link is purely in the error, the final cumulative error will be larger, so that now this monster is like falling apart, although it can run but the efficiency is too low, and it is long, making people feel that its interior is like the Great Song Dynasty, it seems to be running but there is a conflict so far.

"What makes me wonder is that it hasn't fallen apart until now?" Wang Yan suddenly said such a shocking sentence, which made all the participating craftsmen look at each other.

After looking at it again, Wang Yan clapped his hands and said, "Very good, this proves your intentions and exquisite craftsmanship." ”

spent countless money to build such a crippled monster out, and was not dragged out and hung up to fight, and was praised. This made the technicians breathe a sigh of relief, and they all became bloody.

But the craftsmanship can be called artistic, and Lao Luo, who has always pursued perfection, is not happy, thinking that this is a waste product and a failed thing. There is still much to improve.

After continuing to take a look, Wang Yan was mentally prepared that this machine would fall apart, but he just didn't see it fall apart, after all, most of the processes are forged by masters with high-end technology, and they are not so easy to damage.

What's even more awesome is that the team watched the monster run until the afternoon, and its clattering sound has decreased on the contrary, and the vibration is not as strong as before.

Most people don't know much about it.

Wang Yan clapped his hands and said, "Everyone, this is called running-in." The greater the process defects, the more they need to be run-in, and if there is a conflict between the parts and the parts, they need to be twisted, but your Seiko forging has caused its overall strength to fall apart not so easily, so it will be partially run-in and compromised, just like politics, although it is sick, it will compromise with each other to a certain extent, and after erasing their respective edges and corners, the conflict will not be strong. ”

Lao Luo's father thought about this for a while, nodded and said: "My lord is wise, what he said is true, but this means that the gap error between them is greater, and the efficiency index is greatly reduced again." ”

Wang Yan nodded and said, "That's for sure." But I don't have a perfect OCD, I can use it, and I'm sure if I continue to run in, the conflict between the parts will become smaller and smaller, and the efficiency will gradually decrease, but it just works. ”

The crowd looked at each other again.

After observing for another half an hour, Wang Yan said again: "Don't be discouraged, I'm sure this thing is not called industrialization, because except for your joint efforts, it cannot be created by others, that is to say, it cannot be copied, but it is really a black technology in our hands." There is also a way to reduce wear and improve efficiency. ”

Old Luo's eyes lit up and said, "What should I do, please show me?" ”

Wang Yan said: "Reducing the speed and expanding the scale of the machine, these two measures are immediate. ”

After explaining it specifically, Lao Luo's father fully understood. Assuming that the error in manual finishing is a constant value, then enlarging the part is also reducing the error.

So all the early forms of these things will be stupid and coarse, and the smaller the thing, the more delicate it will be.

In addition, running at too high a speed can reduce fault tolerance and rapidly increase wear when the process is not mature. This is a very simple truth, when running fast, it is definitely easier to fall than walking slowly, and the little bell has experienced it.

These must be taken slowly, and through accumulation, the process can be gradually improved. In other words, the industry of the Turkish Communist Party in later generations also started from the fact that the low-speed tractor head could not be built well, and slowly transitioned to medium and high-speed machines, and then to the turbofan engines used in fourth-generation fighters. Intel's chip process also starts from a frequency of 33 and transitions to the third generation of 14nm of 5000+ Hz.

As for now, as long as it can be used, cost and thermal efficiency are not considered.

Then Wang Yan knows better than anyone else that the first few generations of craftsmanship will probably be this virtue, which cannot be miniaturized or refined, and the vibration is too high and the efficiency is too low, which is destined not to be used in the finishing industry. For example, the earliest idea of the big bird was that if this thing could be used as a mechanical power to drive the drill bit to process the barrel, it would be a cow.

Now it obviously doesn't work, it will only destroy all the barrels and drills through that awesome "Megatron" skill.

However, it can be used for the gravel link in cement production, or the large crane on the city wall project, or the mining and conveyor belt operation inside the mine, which can really release manpower to a large extent.

However, this thing can be used to generate electricity, and it is no problem to use the motor to automate the gun manufacturing process. Technically, there is no threshold for the time being. Of course, the conversion efficiency of energy will be outrageously inferior, and there is no commercial prospect for the time being, but it can be used as a technical reserve and as a war potential for entering a full-scale national war at any cost.

However, it is not an egg, thinking that this is just the YY of Da Yan, everything in the world is still a matter of money, now there is too little money, and the volume of Funing County is not too small, and it is not too much to chew, Wang Yan actually has no intention of messing around, and he spends too much money and energy and distorts the science and technology tree.

These YY are all in the future, and now the limited energy and resources can still only focus on the two projects of metallurgical materials and steam engines.

The people in Funing County know that they can't talk about money with Da Yan, but the Great Demon King is never stingy when he issues awards, it's strange that under Da Yan's rule, these guys are very interested in awards.

"You are all pillars of the country and national heroes. Now that the country is full of internal and external troubles, it doesn't have much ability to reward you substantially. I will award the steam engine team a collective first-class merit, each person's name will be recorded on the certificate, this is the honor book, this honor will accompany you for a lifetime, and it will also count your investment in the empire, twenty years later, many people in this team will be ancient, but as long as I am not dead, then your descendants will definitely be able to get this 'equity' cash. ”

After straightening up their flickering and shining eyes, the big goose slipped away......
