The beggar emperor at the end of Ming Dynasty

After half a time, the water in Ding Ding cooled, the surrounding steam was completely dissipated, the following fire has already been out of time, Qin Yu is started to take care of this history unprecedented Ding Ding.

This Ding Ding and the Dan furnace are actually very similar. The only difference is to be high, divided into three parts, and the bottom supporting the whole Dading is the same as the four columns, but only uses a refractory brick, and The cooktore of the fire is almost.

Seeing that Qin Yu's brow wrinkled into Chuanzhu, because this and the machine couldn't be able to do it, but it is the case that the boiler is rare, and it is reluctant to accept it.

But when you see a lid above the boiler, it is back, the skin is a convulsion, and when you find that there is a fist in the lower fist below, you can't help but feel it.

"When you are hard to add water, pull this wood plug, add water here, then plug it?"

"Your Majesty."

Everyone did not think this is something wrong, don't you block the steam?

But if you use copper iron, how can I pull it out? So the best solution to the root wood plug is convenient and effective.

"It's not good to use the wood plug. Now the steam pressure is small, naturally no problem, once the steam is big, the wood in which this hard plug goes will be squeezed, so it is necessary to use metal."

Qin Yu is just a saying that there is no explanation, but the truly machine in the next side has left, because this boiler is indeed simple and rude, there is nothing good.

The problem of injection port, want to completely solve, you must make the thread, and then with the rubber seal, you can withstand high pressure, and it is convenient to remove water at any time.

If the boiler is only heavy, if rough, then this piston steam makes the Qin Yu's embarrassment.

Because the entire machine is square, in addition to the main frame is iron, all the faces are made with a wooden board. The iron tube connected above is used as an air outlet. The structure of the inside is not guessed, and it is sure and the water truck is almost. With the impact of steam, drive the blade inside, this is the power of power, then see the ghost.

If the vapor produced by the huge Ding Ding is sufficient, the box is also relatively sealed, and there is a gap around the iron root stretched out, otherwise it is absolutely unhappy.

"Disconnect it, look at the structure inside." Qin Yu turned a circle, pointed at this cabinet, and his heart is also very speechless.

This guy completely used the steam machine as a woodworking, if he had repeatedly stressed the steam machine is a ferrule machine, an estimated they are for convenience, I am afraid it will use wood to build.

Everyone can't know, Qin Yu is crazy to spit, immediately pouncefully and drums. Three down five, divide this steam machine, and many places actually use to connect, and all the accessories have not been removed. Loss slit.

"If you can turn all these parts into iron, it is fine."

Qin Yu looked at the wooden accessories of the land, and also known, I want to really create a practical steam machine, I am afraid I have a long way.

Because this guy is completely speculative, the wood is absolutely could not suffer from high temperatures and vibration, so even he can solve the metal seal and steam boost, this guy is not likely to turn this cabinet into full metal manufacturing.

Sure enough, like Qin Yu guess, the structure is very simple, eight blades are wood, inlaid in a wooden circular, wearing a iron column, although it is very fine, but there is a fart again use?

The only need is the connection point on both sides. It uses a bicycle wheel to connect. It is stuffed with a small iron bead, and the lard is placed, and then it is sealed. Because this guy's woodworking skills are exciting, vibration It is very small and has reached a practical point.

Because the principle of nuts and screws Qin Yutu have already told these people, so on the wood, it is not difficult to say to those old carpenters, and the precision is quite high, but it is completely caught.

In the case where the bearing cannot be produced, this transmission structure of the bicycle wheel is undoubtedly the best choice to reduce friction. Now all the watermols of the watermill are this structure, but there is a metal bead, there is Wood beads.

"His Majesty, how can we increase steam pressure?"

Everyone saw that Qin Yu always did not say a solution, it was some can't wait. After all, this for them, almost unpubated existence, which is more incredible than the metal binding.

"In fact, it is also simple ..." Although the interest is lack, Qin Yu is patient to explain the operation principle, in fact, it is to draw on the concept of the past high-pressure cooker, design a load-bearing valve, the pressure of steam is not reached, only Reach a certain pressure to open the valve.

As for the metal contact seal, it can be perfectly solved with rubber gaskets. It is good to work with Portuguese. Natural rubber has been hoarded, and it is originally used to do wheels.

Everyone heard that the rubber can be used, it is straightforward, because the rubber Tiantongyuan is there, but they didn't expect this to be over, as for the load-bearing valve, although I don't understand, I can say it, it is absolutely Therefore, one by one is wrapped in the palm, and I can't stand up.

Who knows that Qin Yu is a scoop of cold water.

"The steam boost can make a few people try to test, the next job is on how to transform the boiler and the steam machine."

"what!"

"Your Majesty, is this boiler problem? How do steam machines?"

"Of course, there is a problem, you are too heavy, and you can't use copper one-time pouring, this is quite dry, to create the best fine iron, in addition to the bottom, it can be stitched.

As for this steam engine, I think the windmill is similar, so I have to use the fine iron. In addition to the sealed, other components can not appear any wood. "

Qin Yu black face.

"Your Majesty, this ... all the metal is built, it is difficult to get up to the sky, this metal can be threaded, it is very troublesome."

A worker is very shocked.

"Then no screws are connected, directly connected with rivets."

Qin Yutao played, and also know that now I want to make a metal screw, I am afraid that it is unrealistic, the key is that the accuracy is not reached, so it can only be used with rivets.

Connect with rivets, will only be more robust than screws. When you don't see the country's armor warrules, it is a rivet.

After listening to the connection principle of the rivet, everyone is bright, then one of them frown: "According to Your Majesty, if you use rivets, once there is a problem, you will need to force demolition, so Table machine, you must not return to replace it! "

"No matter these, let the steam machine come out and say that he will slowly slowly again."

Qin Yu was swaying. He knows that even if it finally made the steam machine, he wants to mass production, achieving practical sites, afraid that you still have to make many years.

But as long as you make the real thing, let everyone see the magic of the steam machine, there will always be a mass production, and will continue to study the future generations.

In fact, the steam machine they made, does not count the reciprocating piston steam machine, but should be called the rotary steam engine, the efficiency is very low, even if it is boosted, the force is limited, and finally it is unable to achieve practical.

But this doesn't matter, first let the runner steam machine come out and say, so as not to fight their enthusiasm, after all, from the head to the end, they have come out, and finally can turn, it is very can't afford it. A big step.

As for the real reciprocating piston steam engine, they can wait for this steam machine to be improved, and the confidence in the people must be explored, and other research institutes can also motivate other research institutes.

So, although the rough principle of some reciprocating piston steam engines, Qin Yu has not told them that it is inevitable that they have affected.

Instead, I plan to wait until they finished, and then tell them, and have accumulated some experience and technology, I believe that I want to make a real steam machine, can't spend more time.
