People in Datang have been expelled from school

Chapter 598 Efficiency
Li Zheng was sitting in the village at the moment, not far from the almost completed printing factory building.

Li Jiangshan stood aside and looked at Li Zheng with a decadent expression.

I don't know if God is blind, so many skills have fallen to this lazy and unmotivated person.

Li Jiangshan said: "The printing factory is about to be completed. If the queen orders, follow the old rules. The old printing house can be dismantled and merged into the new printing factory. The future benefits will still be divided according to the old rules. After all, this business has Queen's portion."

Li Zheng made a silent movement, and whispered: "Sister Killer, I am thinking about life."

Li Jiangshan: "..."

Now Xu Jingzong has become a spy chief, Li Chunfeng has gone forever on the road of mathematics, and Yan Liben has plunged into manufacturing technology, and it seems that he no longer studies technology.

Li Jiangshan held the horizontal knife and said: "I don't think you need to think too much about your life. You don't seem like the kind of person who has a lot of troubles."

With a melancholy expression, Li Zheng looked up at the sky and said, "Sister Killer doesn't understand, but I actually have a lot of troubles."

Li Jiangshan said: "For example? You married a princess, your family is rich, and you are still the Duke of the county. What troubles do you have?"

Li Zheng raised his spirit again and said: "I am thinking about a problem. For example, if there is a circular container, first fill it with steam, then seal the inside, pour cold water on the outside to cool down, and the steam will condense to form a vacuum. , then open the water valve, and the water will be pressed into the container by the atmospheric pressure, sealed and heated again, and then open the water inlet valve, and the water will be sucked into the container by the atmospheric pressure; close the water inlet valve, and reopen the steam inlet valve , thus forming a cycle.”

Li Jiangshan: "..."

Li Zheng nodded and said, "That's right, that's what I'm thinking about now."

The expression on Li Jiangshan's face was very tangled, as if he had eaten a very sour plum.

"You see, this is what I'm thinking about. It's complicated, right? In fact, it's also simple. It just uses condensation, vacuum, and air pressure."

Li Jiangshan regained his poker face. This question was quickly forgotten. It is not a question that people of the same level can think about, but he still asked with a straight face: "What did you just say? Is it a container?"

"Actually, it's not air-conditioning. That thing is called a steam engine."

"What chicken?"

"It's nothing."

Li Zheng sighed melancholy, and then walked into the printing factory again.

Whether the printing factory is big or small, it only occupies about ten acres of land.

The rotary machine has been installed, and Li Zheng is inspecting these parts carefully.

Yan Liben and several craftsmen are still busy, and there are still many places in the printing factory that need to be repaired.

Looking up at the roof, Yan Liben looked at the top of his head and said, "Chang'an Ling, why is the roof so high?"

"For future needs, we need to reserve space."

Yan Liben nodded slightly, "Does it need to be repaired on two floors?"

Li Zheng also looked up at the roof and said: "If you build two floors, the upper structure will not be strong, and the printing presses in the future may need to be improved."

Yan Liben nodded after listening, "You mean to build something very tall?"

Li Zheng did not deny it, and then checked the rotary machine.

In the next ten days, Li Zheng lived in the printing factory and tried the rotary machine again and again.

Holding a bowl, Li Zheng said to Li Yifu while eating, "You pour all the pulp into the feeder at the back."

Li Yifu arranged everything here according to Li Zheng's instructions.

After eating a few mouthfuls of rice, Li Zheng wrote on a wooden board, the 730th experiment.

Putting his rice bowl aside, Li Zheng said, "Start!"

Li Yifu shouted at the same time: "Start!"

Words spread all the way to the back door of the printing factory. A small water reservoir was built next to the embankment of the village to irrigate the fields due to reclaiming new land.

This is the reservoir built when cotton was first grown.

The valve of the reservoir opened a gap, and the water flow began to hit the water wheel. The water wheel rotated to drive the transmission belt behind, and the conveyor belt on the rotary machine also began to rotate.

Then several villagers began to turn the pull rod, and one end of the conveyor belt was in the vat full of pulp. As the conveyor belt rotated, the pulp brought out stuck to the conveyor belt, and the villagers standing one by one began to divide the pulp. The pulp is quickly dried in a furnace, and then the semi-solidified paper is manually molded.

Put it on the second-stage conveyor belt, dry it again, press it, dry it and print it, and a long sheet of printed paper will come out.

"Success!" Yan Liben's eyes became excited when he saw a brand new piece of paper.

Tie Da was also staring at the rotary machine. Most of the rotary machine was made of iron. After half an hour, the rotary machine got stuck again.

Stopping all actions, Li Zheng checked the reason.

After checking, there was still a problem with the rolling of the wooden structure. Li Zheng said to Tie Da: "All the five wooden rollings in the front, back, and middle are made into iron barrels. The wall of the barrel is about ten centimeters thick. Under this condition, the lighter the better. "

Tie Da went to work after receiving the words.

More than 700 tests, three days and three nights, this run is the longest one.

An assembly line, from pulp to paper to printing in one go, Li Zheng really did what he said.

In half an hour, a total of 670 sheets were produced, which was three times faster than the current printing house.

Under the hydraulically driven rotary machine, the speed of the conveyor belt is very slow.

If you want to improve the efficiency, you can't drive it with water power.

The idea of ​​a steam engine is not unheard of, and it is too complicated to do.

To increase the efficiency to ten times or even thirty times, the power problem must be improved. It seems that the steam engine has to do it.

I have also seen the steam engine of the [-]th century in the system library. The manufacture is very cumbersome and there are many problems to be solved. The first is the level of iron and steel craftsmanship.

According to the current level of Jingyang, it is a bit difficult to build a large steam engine, but you can try it.

Li Zheng hadn't been home for a few days. Li Lizhi came to the printing factory and saw a dirty Li Zheng, "It's rare to see you in such a mess."

Seeing Li Lizhi, Li Zheng also looked at himself. There was a lot of dirt on his clothes, and the cuffs were already horribly black. He didn't know that his hair hadn't been washed for a few days.

Li Zheng told Li Yifu a few words, and followed Li Lizhi home.

Back home, Li Zheng took a good shower and changed into clean clothes.

Li Lizhi made a cup of tea for Li Zheng, "How is it?"

"The assembly line has been settled, and the problem should not be serious. It is confirmed that the operation of the assembly line can now be improved in terms of performance."
