Wan Xueer doesn't understand steam engines, but Bai Minghe understands it. He dare not say that he is very proficient, but he still understands the basic principles. For Daming at the moment, the most difficult problem to solve is sealing and work efficiency.

Single flow is definitely not suitable.

Bai Minghe asked Wan Xueer again: "You are talking about air, not steam, right?"

"Yes!" Seeing Bai Minghe so serious, Wan Xueer immediately gave Bai Minghe a positive answer.

The power required to inject air into the steel cylinder is definitely not something that can be achieved by single-flow. Bai Minghe himself has not drawn a complete conceptual picture for high-end things like steam turbines, so the people from Xingshou Hospital have definitely not made it, so the only thing that can be used is the reciprocating single-flow type.

And it must be of multiple cylinders, otherwise it is impossible to output stably. After the steel cylinder reaches a little atmospheric pressure, the force without stable output will be pushed back by the air pressure of the steel cylinder, and it is impossible to reach the level of bursting the steel cylinder or pressurizing it to the emission pressure.

"Call Huaiyu." Bai Minghe took off his silk clothes after a few strokes: "Change me in linen clothes."

Huaiyu was thinking in the room. Bai Minghe was finally back. Should she pretend to be pitiful, should she cry, or make noise? That one works even more. She finally found some fun things, and Angela was still waiting for herself to solve the problem of sealing the workshop door.

Sun Yuanjun, this sister is becoming more and more disloyal to love her. She has destroyed two houses and blown up a few walls.

While Huaiyu was thinking about how to show off Bai Minghe and then giving him a good word and lifting the workshop, a maid trotted over: "Your Highness, the young master, the young master ordered him to change into the workshop cloth, and the young master asked your princess to accompany you to your workshop."

"Ah!" Huaiyu exclaimed, very happy.

I quickly changed my clothes and sent someone to notify Angela. Of course, the most important thing was to find those people who broke up and inserted into other research groups in the Xingshou Hospital.

For Huaiyu, Bai Minghe was willing to see the design they created, which was a very happy thing.

Bai Minghe left the mansion and left in a hurry. He had never explained it to anyone. Just after Bai Minghe left the mansion, Wei Shaoqing came. The Emperor of Ming Dynasty summoned Bai Minghe. The people in Bai Ma Pavilion only knew that Bai Minghe went to the workshop of Shanglinyuan Xingshouyuan. None of the rest was known. Wei Shaoqing had no choice but to go back and report.

Emperor Zhu Qiyu of the Ming Dynasty was discussing the location of the trial planting of new grain with Yu Qian.

Nanjing chose a few suitable places around Nanjing and reported it. For the six ministries of Nanjing, this is not a trivial matter. High yield of new grain is a major issue for the country, so it is naturally necessary to report it.

So Zhu Qiyu also wanted to hear Bai Minghe's opinion, but Wei Shaoqing went to the Shanglinyuan Xingshouyuan Workshop.

"Why don't you go to the workshop?"

"If you go back, let alone slaves, there are less than a hundred people in the entire Nanjing city. Those who can enter the inner workshop may be counted with one hand. Even Wang Cheng is in charge of the defense there, and there are only tokens from the outer door. He cannot enter the inner door casually, and there are cannons on the wall of the inner door." Wei Shaoqing came to Nanjing. In order to protect the emperor, he understood many rules in Nanjing.

"Go and see. Don't force yourself to break in, just say I'm going." Zhu Qiyu said to Qian after instructing him: "I'm afraid the real treasure of the White-Minned Crane is here. I know that the Tianyin Ji is made there, and it is reasonable to keep it tighter. I have also ordered the verification of all three generations of craftsmen."

"Long live, I want to go and see it." Yu Qian was curious. He was also curious and had expectations. He immediately said to Zhu Qiyu: "Long live, Bai Minghe said that he could get the goods from Xi'an Prefecture to Tulupan for five days and five nights. I am looking forward to it!"

On the other hand, Xingshou Academy Research Center.

There are already samples of the steam engine here. There are four sets, three of which are genuine from the workshop, and one is very alternative. It is found by Huaiyu and Anqiya from the physics books of Baiminghe, and then designed it by themselves. Not to mention whether it is reasonable or not, it can be used at least.

Before the three sets of other units are best tested and tested, Bai Minghe first saw the set made by Huaiyu and craftsmen.

"Sir, although this set is very powerful and very easy to damage, it provides several very excellent ideas. Because this prototype is the third machine that we can actually use, we will complete." The craftsman in charge here is to tell the truth. These people don't know how to flatter people or flatter people.

Huaiyu was unhappy when she heard this, and Bai Minghe signaled her not to speak.

When I opened the lid of the machine, Bai Minghe only looked at it and knew what it was: "V-type four-cylinder single-flow type. This design is very clever, but I cannot make super steel for crankshafts now. This kind of round steel sheet is not suitable at all."

Bai Minghe immediately drew a real car crankshaft with a pencil.

"This is the best crankshaft. If the material is too poor, it will not be strong enough. But if the material is good enough, then Huaiyu and the others can use it. It is still the same old saying, don't ask for the best, just want the best."

"Sir, wise!" Jiangshitou added: "The design of the spherical throttle valve is more suitable than the original opening and closing type. However, it can only be used for vertical steam engines. The best use of horizontal steam engines is a parallel path valve or a conical valve."

Bai Minghe has done a good job in physics.

Their usage is to add a cone to the piston of the steam pressure chamber of the steam. When the exhaust gas rises, this cone will push open another cone at the inlet, and then let high-pressure steam rush in and push the piston again. Then, because the piston drops, it does not have the power to push the cone, and closes the inlet.

Then the steam tank on the other side will repeat this action.

This is a horizontal reciprocating single-flow steam engine, because it is very long, and it is definitely the most suitable for train use.

Then if you add a gearbox, you can also use it for the generator.

Baiminghe's test will definitely not be enough to just turn the steam engine. He needs a weight-bearing test. The most appropriate way is to have a railway, which doesn't matter if it is short. You can make an attempt.

"How many rails are stored?" Bai Minghe asked the people beside him.

"If you want to go back to the Lord, the twelve steel is now 7,000 feet. The high-quality wood transported from Nanyang has been 100,000 feet, and there are still 90,000 concrete stone pillows, which are still in production. Just because you are in the north, you are unattended, and many things are waiting for the orders of yours."

Bai Minghe reached out to pat the steam engine that the craftsmen thought was the most perfect.

"It's good or bad, you always have to try it to know. This thing is very powerful, and ordinary small objects are not worth trying. When you try out its power, hurry up and build the wheels. I want to see how many cars it can pull!"

"Yes!" Everyone responded in unison.

The steam engine is not difficult. With Eucommia glue, the sealing problem is solved. With high-quality steel, these are not difficult.

The only difficult thing in China actually had a solution hundreds of years ago, that is, welding. The original welding technology was already in place in the Spring and Autumn Period. The welding used by the Ming Dynasty now was to buckle the burned red steel plate and then forge it, which was the forging and welding technology of the Ming Dynasty.

Compared with modern technology, this is naturally not worth mentioning. In this era, it can produce a thick steel cylinder with a length of four meters and a diameter of more than one meter, and ensure that there is no leakage. This is enough to prove that the Ming Dynasty's technical level is already extremely high, even if it takes ten excellent blacksmiths to work hard for a month for making such a steam engine.

"Brother-in-law, why don't you care about the one we made, that one is also very useful." Huaiyu saw Bai Minghe finishing his work, then he held Bai Minghe's hand with an unhappy look on his face.

"Your this is easy to use, I have an idea. But this time, don't pull the main craftsmen, just take some action to work for you. I'll give you an idea. Let's first let the steel mill build a propeller, and then use this steam engine to power the ship?"

"Boat?" Huaiyu didn't believe it.

But the white-famous crane was full of confidence and began to draw on a piece of white paper.

It is impossible to use a real propeller in the base warehouse. The problem of sealing the shaft alone can kill people. Therefore, the Baiming Crane painted the shape of a big water truck, and the large rowing wheel placed on both sides of the hull. This thing can definitely replace manpower to row, and it doesn't take too much trouble to make it.

Pick a flat-bottomed river boat in the Ministry of Industry's shipyard. Don't have too many, as a thousand materials is enough.

Without having to take the sail, start the modification directly, and then add large rotors on both sides. Baiminghe estimated that the speed of this thing was all released. In the state of an empty ship, it could definitely exceed fifteen knots. Of course, the buildings on the deck were significantly less severe and the weight was reduced. Baiminghe was confident that this thing would reach twenty knots.

One more important reason is that although the steam engine like Huaiyu is not strong and durable, it is lighter than the bulky and practical one and has a higher speed.

Of course, it is not the kind of person who is scrapped after running once. He can run a thousand or two miles before changing the axis.

Without high-precision lathes and high-strength steel, we can make original crankshafts with the same principle. We must say that this is definitely because of silver. This is the design result of spending silver. I don’t know how much labor and steel are wasted.

The white-famous crane was drawing on paper, explaining to Huaiyu and Angela.

On the other side, the Emperor of Ming was standing at the door. As the Emperor of Ming, he could naturally enter, and no one dared to stop him. Yu Qian could say that at least he could come with the emperor. But those who accompanied him were not good at it. Even if the guards here came out of the Forbidden Palace, they would not dare to let it go casually if they knew it.

Record one by one, check your own items.

Zhu Qiyu sat aside and watched, not only not angry, but said, "Since this place is important, you must guard it with your heart. If there are idle people who dare to break through, I will give you permission to draw the line in front of the door. Those who cross the line can take action first and then report. Especially in the Tianyin Ji Camp, you must guard it tighter!" (To be continued...)
