The equipment in front of him has completely attracted everyone's eyes, and the development and manufacturing of the steam engine, although it has not been deliberately concealed. Pen %Fun %Pavilion www.biquge.info but there is no hype.

Only a small number of people, mainly at the level of city lords, like to go to Yao Huo and Xiaoping to ask if there are any new tools that can be used.

But until any large piece of equipment is assembled, it's like a child learning to play the violin, and no one can hear the tune until it's finished.

Before the steam engine was assembled, there were scattered parts all over the floor, ceramic pipes, all kinds of iron sheets, pistons like large round iron ingots, and nothing that could be seen as a reason.

Of course, when it was almost assembled, this steam engine was more like a huge bucket with pipes inserted into it, and the bucket contained a few stirring rods. The pipe is attached to the large kettle.

With Yao Ran's order, Yao Huo and Xiaoping began to put some charcoal in the fire and ignite it, and then put it into the boiler, because the big kettle is too big, especially in the ordinary heating method, a large kettle of several cubic meters.

Yao Ran did not put forward opinions at this time, but watched everything silently, and then kept it in mind, and finally when it was time for unified improvement, he could naturally avoid these problems.

Therefore, now watching the steam engine is more important, Yao Ran wants to use the retinal system to do a comprehensive inspection, including life durability, maximum power, maximum load, and then see how to improve it to run a higher power.

The next picture became a little funny, more than a dozen big men, squatting in front of a stove, and a big kettle fell from the top of the stove, which was actually a large closed water tank.

In fact, this boiler is really a dangerous thing to stop, because without a pressure gauge, you can't see the reading. There is no way to control the temperature of the heat.

This problem really seems like a solution. Now that glaze firing can be achieved, what about glass? I think I can try to do it.

With the presence of rubber, it is not a problem to make a closed pressure gauge. Especially Yao Ran also has an invincible multimeter in his body, and the counting statistics have saved a lot of troublesome problems.

The production of pressure gauges is also necessary, and Yao Ran can only do it after making improvements. After nearly an hour of squatting in front of the stove, Yao Ran saw the entire inside of the boiler boiling in the retina system, and the gurgling sound continued to increase.

This time, without letting everyone wait too long, the steam entered the cylinder through the pipe, and the sudden pressure made the entire piston rod begin to move slowly, including the previous one, and the sliding rod also moved at the same time.

At the beginning, what Yao Ran gave Yao Huo was not a primary lever steam engine, but the way of splicing the crankshaft, which was found in Yao Ran's retina system, because this is the application method of the external engine of the horizontal steam engine.

It is also the kind of external combustion engine used on the steam locomotive in Yao Ran's own memory. Of course, the external combustion engine on the train is more powerful and more powerful. And Yao Ran's here, Yao Huo and the steam engine they made, although it moved, but there was a tooth-sore friction sound.

Yao Ran, who used the retina system, checked it, and the sound came from inside the cylinder, and Yao Ran clearly saw that the piston inside the cylinder was not equipped with a rubber cushion, because the contact of the metal squeezed and slid together, it was strange to make a good sound

In this way, there is only such a cylinder, and the piston is not filled with rubber, and the air tightness is reduced. As a result, the energy loss of the entire steam engine is very large. If there is a problem to solve the problem, I am afraid that I will not find out what the problem is. When the time comes, there will be no problem, and I don't know where the fault is.

The friction of these two parts will definitely wear the metal thin for a long time, and then either the cylinder block will crack or the air leakage will be more serious, resulting in the inability to work.

Yao Ran shouted to stop and remove the furnace fire, and the entire steam engine discharged the steam from the exhaust pipe, and no longer supplied the cylinder for reciprocating motion. The cylinder piston moved slowly a few times under inertia and then stopped working.

"Demolition!" Yao Ran said a word, but Yao Huo and Xiaoping didn't move, and Yao Ran himself didn't move, but Xiaoping and Yao Huo didn't know what the teacher's specific evaluation was, but when they heard the word split, they only knew that the results this time should not be much better.

If it can be used, of course, there is no need to disassemble it, you must know that this steam engine was used in large quantities and riveted for air tightness and pressure resistance. It's easy to rivet and connect, but it's even harder to remove.

But Yao Ran doesn't care who is responsible for this problem, whether you use burns or buckles. In short, it must be disassembled and improved, otherwise there is so much iron here, won't it be wasted?

Yao Ran called Yao Huo and Xiaoping, took out a large piece of blank paper, and began to draw and talk to the two of them, and there were still gathered around Yao Huo and a group of Yao Ran's apprentices, Yao Huo is not very old now, but he is also a top scholar in the entire Yao clan.

Just being able to understand complex drawings is already an existence against the sky, and even if the drawings are in the hands of literate people, they are like heavenly books, not to mention, the literacy rate of the entire Yao clan is only 20 percent now, of course, the original literacy rate is still close to 50 percent.

But this trip to the Great Snow Mountain, the population of the entire Yao clan suddenly skyrocketed, so naturally the percentage of the previous completion was compared, as for why the slaves were counted, because slaves are also human beings, independent thinking, healthy human beings.

In addition, it can be unceremoniously compared to a game, the Yao clan is a paying player, and the slaves are non-paying players, which belong to the entertainment of paying players.

So of course, the population of slaves should also be counted in it at the same time, and in the future, these slaves will pass, Yao Ran will intentionally control the population development of the barbarians, and after a few decades of integration, the bloodline of the barbarians will become less and less, and they will gradually disappear into Yao Ran's power, of course, it will be many years later.

Speaking of looking at the drawings, Yao Huo has already been highly respected, not to mention, the problems in technical production, including the fact that it can be said that the scientific and technological products in the entire Yao clan can only be sent out under Yao Huo's nod. Of course, this kind of logistics ratio work is not done in vain.

Whose things are sent first, and whose things are sent later, Yao Huo has the final say, so Yao Huo's prestige in the entire Yao clan is really not low.
