The thick pipe in the middle has a unique way. There is something similar to a piston in the middle of the pipe. There are two vent valves on the pipe body located on the left and right respectively. The entire communication pipe is like an engine cylinder.

When working, the left valve opens to release the steam of the left kettle, and the right kettle is closed. The high pressure of the right kettle will push the piston to the left. When the piston is completely pushed to the end of the left side of the cylinder, the left valve is closed, and the right valve on the other side is open again to release the steam of the right kettle. Now the pressure of the left kettle increases, pushing the piston to the right. This is considered to have completed a stroke.

The piston is connected to a swing rod to the outside, which is equivalent to converting the movement of the piston into power.

This is an extremely simple steam engine, which only applies the steam principle, but it is not the same as the Watt steam engine in later generations!

Moreover, power transmission is not a circular motion of rotation, but a linear motion of swaying left and right.

Well, it’s already great that Yisimayin can do this at her current level.

Then again, since the principle is correct and it has been created and can still move, why are you so frustrated?

Because the process does not meet the standards! In addition, the utilization rate is too low!

First of all, it is the craft. When everyone lights the fire and boils on the left and right boilers, Zhao Wei will understand why the people outside complain.

How come this is a steam engine? This is an open-air sauna!

This is a big deal. His blacksmith's skills are not up to standard. He should have been a sealed boiler, but air leaks everywhere!

The cylinder in the middle is not good either, and the piston is even worse than that. Zhao Wei can hear the sound of the gas from the left pot leaking to the right pot through the gap of the piston.

Such a manufacturing level, the thermal efficiency can be imagined. A large boiler worth ten feet high

In later generations, steamed car heads that were used to pull more than a hundred car skins would not be able to use such a large boiler! But the actual power generated is very, very small!

Yes, even a seven or eight-year-old child can hold the piston down!

Then there is the speed of the piston movement

This is also the main reason why everyone completely lost confidence

It’s no wonder that a group of old men and women would be like them if Zhao Wei was here just now.

Even now that he is mentally prepared, His Highness Ning is anxious for the machine!

Later generations said that the engine was at least one or two thousand rotations? It was idle at 7.8 hundred. It was normal to step on the floor oil for five or six thousand rotations.

Of course, it's oil-burning, it's incomparable to steam

But it's at least the same, right? Not to mention 7.8 hundred revolutions per second, it's the total amount of time per minute?

But this thing

Zhao Wei stood there for a while and there was about 2 turns?

Every minute!!

That's right! In one minute, the damn piston walked back and forth twice

Otherwise, what if Lao Yixin is dead? He realized that the steam engine is not reliable!

But despite this!!

Although Yi Sima made waste! Although this thing has no practical value.

But then again, even if it is a pile of industrial garbage, it is also industrial!!

"good!!!"

Zhao Wei suddenly shouted loudly, scaring everyone!

Look at him in surprise, OK?

What's the best? Which one is better?

After the steam dissipated, King Ning's handsome face leaked in front of everyone, as if he had eaten ginseng treasure!

Lao Yi saw it and smiled bitterly, "Your Highness, don't need to comfort us."

"Comfort!" Zhao Wei was speechless, "You still need comfort?"

"I thought this thing could fart! What else would you be dissatisfied with with such achievements?"

Lao Yi: ""

Everyone: ""

Everyone thought to themselves, Your Highness is still a good person, and he is like this, can he still say such unconscience-ridden words?

However, they didn't know that Zhao Wei was really uncomfortable.

He felt that it was a miracle that these people could use it for a year to build the steam engine to this extent!

You know, later generations believed that Watt invented the steam engine, but this statement is wrong.

Watt did not invent the steam engine, Watt only invented the steam engine that can be actually used in industrial production!

The steam engine was founded very early before Watt, but it was similar to the steam engine built by Yisimayin. It only proposed the principle of steam and created a physical object.

To put it bluntly, Watt just completed a wonderful "industrial design" principle and the prototype had nothing to do with him.

Without those pioneers, there would be no Watt's steam engine!

The same principle can also be used on Yisimayin and others. They do not have the ability to get the Watt steam engine out in one step.

But the prototype they created accumulated the theoretical basis of the steam engine.

This is no less than building a watt steam engine directly. It is also very impressive.

Since this primitive big guy has arrived on the surface of the earth, is the steam engine that can be used really far away?

Moreover, from the corner of Zhao Wei's eyes, this prototype may be far more valuable than directly building a watt machine!

And it is not a little valuable, but a thousand times more!

The reason is very simple

If it weren't for Zhao Wei, maybe Yi Sima Yin, A Lao, Xu Liang and others would give up seeing that this thing was not of great value.

This is human nature, and it is not surprising.

But with Zhao Wei, Zhao Wei told them that the idea was right and they should continue to move on.

So how much more will Da Song get from the starting point of this prototype?

The most straightforward truth is, w. If they continue to develop on the basis of this prototype.

Then we need to solve the problem of airtightness? We need to solve the processing accuracy? We need to improve thermal efficiency? We need to be precise and precise if we can solve the existing technology and materials. If we cannot solve the existing ones, we need to invent and create.

Using this as a driving force, how many related technologies, exploration and invention will be driven?

What we harvested in the end was not a simple steam engine.

But the comprehensive improvement of related theories, processes and technologies!

What drives the overall industrial level of the Song Dynasty, which is the greatest value!.
