Steam Daming: Stop calling me to supervise the country

Chapter 16 Steam [-]WD

Under the gray cloth is an iron lump, which is basically the same as the shape on his own drawings. First, we observed the joints. Although the welding technology of metals is far from modern, we can know from the tightness of the welding joints that these builders The craftsmanship of the steam engine is quite remarkable.

Metal welding will affect the tightness of the steam engine. If there is no tightness, the steam will leak out at will, then the machine will definitely not be able to rotate.

"Master, what is this iron guy doing?"

Zhu Zhanchang smiled slightly: "This is the improvement of the kettle that I showed you before."

"The difference is too big."

"It's just the difference in appearance. The principle is actually the same. Xiaosheng, go get some coal."

Xiaosheng went to get a small basket of coal blocks, and Zhu Zhanchang took advantage of this time to fill up with water, and ignited the coal blocks and started to burn.

As the steam rises and pressurizes the device continuously, the pressure starts to push the internal piston to move, and the connected wheels gradually move. As the wheels rotate, the pressure relief port emits steam.

Alternating the wheels in turn really starts to turn, but the efficiency is very low, the speed of rotation is very slow, and it cannot be used in real applications.

If you can turn it, it means that there is an opportunity, and the direction of effort is right.

"Xiaosheng, ask someone to invite Lord Zheng He." As the grandson of the emperor, he couldn't easily leave the palace, but it was a little easier for Zheng He to come in.

Xiaosheng was about to go out, but saw that Zheng He had already arrived at the door, full of smiles.

Said that Cao Cao Cao Cao arrived.

"Five sons." Zheng He saluted with a smile on his face.

"Master Zheng, I'm about to let someone go to find you."

Zheng He said unhurriedly: "Fifth Young Master, have you tried the new steam engine?"

"I have tried it and it can be used, but the efficiency is too low to be used for real."

Zheng He naturally knew that they had tried many times.

"Young master, come with me to the front of the hall. I sent a steam engine to your side and also to your majesty and the prince. The prince ordered me to show the craftsmen, and the craftsmen insisted that you also come along."

This semi-finished product was actually delivered to the emperor, but it is also true. In the eyes of Zhu Zhanchang, it is only a semi-finished product, but in the eyes of people of this era, this is a great technological leap.

As Zheng He came to the Fengtian Palace, the meeting of the ministers had broken up. At this time, only Zhu Di was sitting high on the dragon chair. Zhu Gaochi and Zhu Zhanji, who had just slept for a while, were by their side, and there were two others beside them. The ministers are Yang Rong and Xia Yuanji.

Below the steps are Zhang San and several other craftsmen, as well as a car with a steam engine.

Zhu Zhanchang had to go to Zhu Di's side first to say goodbye. He glanced at the car from a distance and thought it was weird, but he couldn't tell.

"Happy grandfather."

Zhu Di said with a smile on his face: "Zheng He said that you made the iron lump?"

"Grandpa Huang, I just thought about it and drew a blueprint. It was only this morning that I saw that Master Zheng and a few skilled craftsmen really made it."

In the face of Zhu Zhanchang's refusal to take credit, Zhu Di was quite satisfied.

Zhu Gaochi continued: "Your Majesty, this is the steam engine that Zhan thought of when I mentioned to you before."

"You can drive without a horse, and a boat without wind. The idea is really novel. Zheng He makes it move and show me."

"Yes, Your Majesty."

Zheng He was about to start people, but Zhu Zhanchang hurriedly stood up: "Grandpa Huang, wait."

"what's up?"

"Can I let my grandson come forward to take a look first?"

"Go."

Zhu Zhanchang walked all the way down the tall steps, and his eldest brother Zhu Zhanji came down together.

"Five sons, His Royal Highness Taisun." Several craftsmen greeted.

Zhu Zhanchang took a close look at the car and found something strange. This group of people actually installed a steam engine on each of the four wheels, giving Zhu Zhanchang a black line.

This is not a steam four-wheel drive car, and I think about building a four-wheel drive vehicle before I understand the front-wheel drive and rear-wheel drive.

They thought a steam engine could only drive one wheel, so they thought of putting four on a car.

That's right, Zhu Zhanchang hasn't told them anything about gears.

"Master Zheng, have you tried the car?"

"I tried it." Zheng He was a little embarrassed, obviously the situation was not good.

Zhu Zhanchang broke it in one sentence: "Is it possible that the four wheels have different rotation effects, the car can only move a little bit, and then it breaks."

Zheng He and several craftsmen looked at Zhu Zhanchang in astonishment. What Zhu Zhanchang said was basically the situation of the experiment.

Zhu Zhanji, the good eldest brother beside him, asked inexplicably, "Zhanchang, what's going on?"

"Brother, although the four steam engines are ignited together, the amount and speed of steam produced by the coal burning are different, resulting in different effects of each wheel's rotation. Four wheels and four ideas, how can this car be able to drive? ."

Zhu Zhanji nodded in understanding but not understanding. Young people are quicker to accept new things.

"Is there a solution for the young master?" Zhang San asked impatiently.

"Yes, but it's too late now. It's not good for Your Majesty to let His Majesty see the steam engine like this."

Zheng He was indeed full of confidence: "You don't have to worry about the fifth son, this is a preliminary test product."

In the end, Zheng He started the test with full confidence. I don't know if it was God's help or just luck. The car really started, and the sound of steam escaping from the pressure relief valve was more regular.

No one was in the car, no horse was in front of the car, but the car actually moved, so shocked that Zhu Di stood up from the dragon chair.

The car ran for more than ten meters, and then fell apart directly. In this way, no one controls the car without brakes, and the final consequence is only destruction.

Zhu Zhanchang was not satisfied with this situation, but beyond his expectation, Zhu Di, Zhu Gaochi and others were already excited.

"Do it, then do it for me. Weizhe should have enough money in the household department to do this."

Xia Yuanji woke up from the shock and hurriedly saluted: "Reporting to Your Majesty, the Ministry of Household must fully support His Majesty's initiative."

The people present saw the car that could run more than [-] meters by themselves, and they already understood that this was a ground-changing innovation. It was the first time since Pangu opened the sky. In the past, he could only hear the guide that does not require manpower or horses in myths. car.

Seeing with your own eyes, seeing is believing.

Zheng He stepped forward and saluted: "Your Majesty's steam car still has a lot of room for improvement."

"Change, no matter what the cost, let me change it until it's good."

With the full support of His Majesty the Emperor and all-round resource inclination, can the whole country be able to do well?

Zheng He went on to say: "Your Majesty, please allow the fifth son of the prince to come to the mansion more. I think the prince already has a solution."

"Go, Zhanchang will send you a token today, you can leave the palace at any time, no need to report, just register at the gate of the palace, no matter how you make the steam engine."

"Grandpa Xie Huang, it's just that my grandson still has classes to attend."

"Gao Chi, you come to coordinate."

"Yes."

Zhu Zhanchang raised his head and looked at Zhu Xi with a smile, Zhu Xi smiled bitterly: "You kid isn't asking for money again, right?"

"hey-hey."
