Carrier gate attic, next to the stone railing.

Zhu Di carved the railing and looked at each other, you could see the entire Yanwang Mansion, walked to the corner of the building on the stone platform, followed by Ge Cheng, Jin Zhong, and a eunuch.

From the corner of the building to the northeast, you can see the eaves of the Sekofu complex.

"Recently, the palace has made a lot of moves, Guo Ying is not out of line, knock it out, if you are interested, you can keep him."

Jin Zhong was calm.

Ge Cheng was on Jin Zhong's left, and after coming out of the attic, he had nothing to say, which seemed a little unusual.

For the newcomer beside him, Ge Cheng had a complicated heart.

In just one year, from the guards guarding the door to the right Changshi of the Changshi Mansion, the speed of the rise is staggering.

Although he knew that King Yan promoted talents regardless of their background, but only made a meritocracy, but Ge Cheng's career made many people stunned.

"That's true." Zhu Di agreed with Jin Zhong's proposal.

In the past few months, the people's hearts in Beiping have been chaotic, and the palace has gained great benefits, and it is indeed necessary to stop in moderation, and he was originally worried about Jin Zhong.

Jin Zhong, Yao Guangxiao, and the eldest son are a little radical.

The proposal of the Lanyu case to be assigned to Liaodong is the biggest adventure of the palace, and it also takes the opportunity to promote cronies.

The release of Sun Yan, Qiu Fu and others caused dissatisfaction among many people.

No matter how big the case is, it is indispensable, and it will eventually be settled.

"Recently, the actions of the second brother and the third brother have subsided, and the palace will also calm down next." Zhu Di stopped and retracted his gaze from afar.

"The biggest gain is the Jin Palace, some people in the imperial court, they should suppress the King of Jin next, and then it will be the turn of the King of Qin, and finally us."

Jin Zhong said confidently.

King Jin was originally not very prestigious, but he took advantage of this opportunity to control the military power of the entire territory of Shanxi at once, but he was more conspicuous than King Yan.

Because of the high prestige of King Yan, he has a foundation in Beiping itself, and some of the things he does are originally eye-catching.

But with the foil of King Jin next door, it is not so eye-catching.

As for the King of Qin.

In any case, when the crown prince died, he was the eldest vassal king, and from the point of view of the name, he was the one who posed the greatest threat to the imperial grandson.

"The crown prince's family will either deal with the King of Qin first, or the King of Jin, and in the end it will be our turn, and we will be able to get at least five years of time."

Jin Zhong's analysis of the current situation is the way, and it really doesn't look like a white body.

But although he is white, in fact, his family studies are much more related than those of the white body.

Meritocracy.

Most of these talents are the children of the people who have no identity and have no identity.

"It doesn't make a difference whether it's five years or ten years."

Ge Cheng interrupted Jin Zhong.

Jin Zhong glanced at Ge Cheng, quietly took a step back and did not refute, this attitude made Ge Cheng speechless.

Where there are people, there are rivers and lakes.

Zhu Di ignored the secret fight between the two right-hand men.

At least the two of them can fight for the palace, if it is Yu Fengchen, this old antique, full of eyes only the way of a saint.

Is the palace not doing anything?

The courtiers hope so, I'm afraid my father won't think so.

The year before last, he also led more than 100,000 troops to the expedition, and the second brother was the same, and his father's plan was to use their trusted sons to expand the territory.

Isn't that what happened in the past?

It's a pity that the officials who read the sage books did not approve of it, and what was even more unexpected was the sudden death of the eldest brother who was in the prime of life.

"What is the boss doing when he comes back from Miyun?" Zhu Di caged his hands and looked calm.

The eunuch stepped forward, bent over and bowed his head, "The eldest prince has been busy with industrial affairs recently. ”

"Industry."

Zhu Di muttered to himself.

Outsiders say that the eldest prince attaches importance to business, and the boss says that this is industry, so the people in the house follow and call it industry, but in fact, they don't understand.

"You go and explain to the boss, and let him choose whoever he likes from the guards, including the palace guards, to be his guard."

"Every day when you run outside, you always have to be guarded, and just a few long-term followers can't do it."

The words of the prince, several people were not surprised.

The name of the prince needs to be decreed by the sage, but in fact, the prince has already given the eldest prince the treatment of the prince.

Zhu Di walked back, as the boss said, the power of the palace has reached the ceiling, and it can only break through from industry.

In the future, only the father can decide the fate of the palace.

Whether the father will continue to follow his previous layout and use the vassal king to expand the territory of the Ming Dynasty, or whether he will be influenced by those courtiers and afraid that the vassal king will threaten the imperial power, no one knows.

Zhu Di only felt that those courtiers were very annoying.

In their eyes, they only see the vassal kings as a threat, so why can't they see the contributions of the vassal kings to the country over the years?

Shizifu.

Zhu Gaochi looked at the report in his hand.

Plan for the construction of water towers in the factory area.

In front of them sat Xiao Jiu, Wang Ben and others.

Among the people who come and go from Shizifu, there are more and more people from China Heavy Industry, accounting for more than 30%.

With the expansion of the scale, the main plant of China Heavy Industry Co., Ltd. and the Miyun branch plant, the needs of all aspects have also changed.

For example, the need for water.

Whether it is domestic or industrial water, more efficient technology is needed.

Orders for coke refineries are getting bigger and bigger, and after the opening of Miyun and Beiping, Miyun Iron Works has become one of the largest customers of coke refineries.

Ten coke ovens are still in full supply, and more need needs to be built.

In the process of coking in coke ovens, a large amount of water is required, which has become an urgent problem, and pumping water with a steam engine is not worth the loss in terms of efficiency and convenience.

"Among the several applications received by the R&D Division, there is a steam engine with a larger pumping power, but after trying, it has never been able to break through, and the current research is in a bottleneck."

"Another application offers a new idea of building a water tower at the height of the current pumping, using the pressure of the water to flow through pipes where it is needed."

"I was amazed by this idea, it was like opening a door."

Xiao Jiu had no jealousy on his face, and his words were full of praise for this idea.

The R&D Department was handed over to Xiao Jiu.

He may not be the best manager, but he must be the one who is the most supportive of the rest of the craftsmen.

Pressurized water wells of the Song Dynasty.

The maximum theoretical depth of the pumping height is 10 meters, but in practice it is mostly 6 to 9 meters.

Before the Newcomen steam engine, Western steam used the birth principle to pass steam from the top of the piston in a copper cylinder, and let it do the work to push the piston downward.

When the work done by the steam is completed, part of it condenses into water, and a vacuum is formed above the piston, and the piston moves upward under atmospheric pressure.

When the remaining space is small, the residual water vapor is ejected by the piston.

But this technique cannot be used to pump water.

In order to meet the needs of the mine, on top of this technology, the Saffrey version of the steam engine was invented, which was the predecessor of the Newcomen steam engine.

An egg-shaped container is filled with steam, then the inlet valve is closed, and cold water is sprayed outside the container to condense the steam inside the container to form a vacuum.

When the inlet valve is opened, the water at the bottom of the mine flows through the inlet pipe and into the container under atmospheric pressure;

Close the inlet valve, reopen the inlet valve, and press out the water in the container through the drain valve by steam pressure.

When the water in the container is emptied and filled with steam, close the inlet and drain valves and re-spray the water to condense the steam.

This repeated cycle, alternating with two egg containers, allows for continuous drainage.

Instead of using a large number of horses, the Saffrey steam pump was used to pump the water out of the mine, a great invention that was loved by the owners and miners alike.

As a result, Safri was affectionately known to the miners as the miners' friends.

But the Saffrey steam engine abandoned the piston technology, wasting a lot of steam, the parts were too complex, and the water was only six meters high.

The steam engine currently used in the factory belongs to the Newcomen steam engine.

The Newcomen steam engine absorbed the advantages of the rapid condensation of the Savery steam engine and the advantages of the piston device in the Paping steam pump.

Steam, which is generated by burning coal, jacks up the piston, and pushes the water lifting device downward.

When the piston rises to a certain height, the water tank next to the piston cylinder pours cold water under the piston, and the water vapor condenses to form a vacuum.

At this point, the piston moves downward under atmospheric pressure, and the water lifting device lifts the water up from a low place.

It realizes the linear motion of pushing the piston up and down with steam, 16 times per minute, and each round trip can raise 90 catties of water to a height of 50 meters.

Fifty meters in height was already the limit of the Newcomen steam engine.

In order to continue to make breakthroughs, it is necessary to solve the problems of insufficient piston sealing, serious air leakage, and the large amount of heat wasted by relying on cold water for condensation after the cylinder is filled with water vapor.

In a word.

Solving these two problems, it is the Watt steam engine.

"The first idea, if it can be achieved, will have a more technologically advanced steam engine, and it is worth investing in it."

"The second idea, which can solve the current problem, is also worth investing in."

Zhu Gaochi took out a piece of white paper, dipped it in ink with a fine brush, and drew a picture on it, on which a tall tower was drawn.

"At present, the height of the steam engine pumping water is 150 feet, and if such a high water tower is built, it can meet the water problem of the entire plant."

Zhu Gaochi emphasized: "Whether it is industrial water or domestic water, it is no longer a problem, and it can save a lot of coal." ”

The biggest problem with the Newgate steam engine can only be used near the coal yard, because the Newdoor steam engine uses a huge amount of coal.

In the past, a coke oven had to use a steam engine, but if a 150-foot-high water tower was built and water pipes were laid, only one steam engine was needed.

Although this steam engine is used to the maximum efficiency.

"One hundred and fifty feet!" Xiao Jiu couldn't close his mouth in surprise.

Dozens of people tall.

"Bricks, iron, wood, etc., you should discuss it as soon as possible and decide which structure to adopt to adapt."

With the current technology, it is most suitable to build a steel frame with the nine irons of the iron-smelting plant, that is, high-density steel.

The five-iron is a low-density steel, although the yield is higher and the plasticity is strong, but the hardness is not as good as the nine-iron.

However, Zhu Gaochi hopes that the R&D department will accumulate more technology.

If masonry technology is adopted, then the traditional cost is too high, and then the cement will be forced into people's sight.
