The pumping process of a water pressor is like a syringe absorbing water, using the pressure inside the syringe to be lower than the atmospheric pressure to absorb water. Pen ~ fun ~ pavilion www.biquge.info

When the piston is pressed down, the check valve below will close, and the check valve on the piston will open, and the function is to flow the water under the piston to the piston through the check valve.

Then it's repeated, and then it goes up, draining the water from the piston and pumping out the water from the ground!

Water presses are often used in various occasions where the water pressure needs to be higher than 10 meters, and now it is used to pump these deep wells up to more than ten meters and more than 20 meters deep, which is the most suitable.

It's just that the water pressure machine is not so easy to manufacture, and the piston inside is the biggest problem, as for the manufacture of sealing cavities and the like, it is not a big problem.

However, Lin Ze has countless pieces of rubber in his hands, so the manufacture of pistons is not a problem for him.

Thinking of this, Lin Ze had a confident smile on his face.

After Wang Ming and Qiu Kai on the side saw it, the two glanced at each other, and they both saw a trace of shock in each other's eyes.

In fact, Wang Ming and Qiu Kai have thought about this problem many times before, and they have also come up with some solutions, and in the end, these methods can be said to be of little use.

Therefore, in the end, he was forced to have no choice, so Wang Ming told Lin Ze this question, wanting to see if this lord, who has always been creating magic, will create magic again.

As a result, something that made Wang Ming and Qiu Kai dumbfounded and admired appeared.

After Lin Ze heard this question, it was only less than a minute before he came up with a solution.

Although Lin Ze hasn't said what solution he has thought of yet, Wang Ming and Qiu Kai, who know Lin Ze very well, knew in their hearts that Lin Ze definitely thought of an excellent solution when they saw the confident look on Lin Ze's face.

"Alas........ , adults are really amazing!" Wang Ming and Qiu Kai sighed in their hearts at the same time.

"Wang Ming, Qiu Kai, come here, I'll give you a good explanation of the solution I came up with. Lin Ze excitedly said to Wang Ming and Qiu Kai on the side.

Wang Ming and Qiu Kai glanced at each other, and soon came to Lin Ze's side, and at this time, Lin Ze had already taken out a piece of paper and drew on it

"Wang Ming, Qiu Kai, come and see, this is the solution I came up with to solve the problem of water suffering, we use a water press to draw water. Lin Ze spread the paper in his hand in front of Wang Ming and Qiu Kai with a smile on his face, and then began to explain to them the function of this water press.

"You see, the principle of this water press is .......... Next, Lin Ze directly gave Wang Ming and Qiu Kai a lesson on atmospheric pressure, in order to avoid them not being incomprehensible, Lin Ze directly said that atmospheric pressure is a force such as true qi, which is more immersive.

Sure enough, in this way, Wang Ming and Qiu Kai quickly understood the principle of the water press, and at this moment, the two of them really admired Lin Ze.

The principle of the water press can be said to be very simple, as long as it is explained a few times, everyone can understand, but the person who can come up with such a simple and practical method is really powerful, at this moment, Wang Ming and Qiu Kai's admiration for Lin Ze in their hearts is incomparable.

"My lord, you are really amazing, your subordinates are very impressed!" Wang Ming and Qiu Kai bowed directly to Lin Ze and said.

"Hahaha........" Lin Ze laughed happily.

It's really nice to be able to let the two think tanks under his command really admire himself at the same time.

What, you said that Lin Ze was too shameless, he was completely brushing his face with things on the earth, and it was simply shameless to do so.

Hehe, I traveled to another world, and I didn't need to brush my face everywhere with things on the earth, so I was a fool.

(Walkers read some novels, after many protagonists come to another world, they will feel very uneasy about copying the culture on the earth, hehe, Walkers just want to say, boy, you are so young!)

I didn't see that the world is full of plagiarized things, even our country is now famous for copycats, so, teenager, don't feel uneasy because of plagiarism, even the country is plagiarizing, you plagiarize, what!

"Wang Ming, Qiu Kai, go and hurry some craftsmen to come, we will solve this problem of difficulty in fetching water as soon as possible. Lin Ze instructed Wang Ming and Qiu Kai on the side.

"Yes, my lord, my subordinates will go and gather the craftsmen. Wang Ming quickly received the order, he was the person in charge of the camp of the homeless camp, and he was most familiar with the things here.

..........................................

Soon, a group of craftsmen with vegetables on their faces came to Lin Ze.

"Knock on the Commander-in-Chief. As soon as these craftsmen came to Lin Ze's face, they directly bowed to the shrine.

Lin Ze felt helpless for a while, but he didn't stop it.

In feudal society, the class hierarchy is very distinct, and on the Shenzhou Continent, there is such a kneeling etiquette, and this etiquette of bowing down to officials has been deeply rooted in the hearts of the people for thousands of years, and it is really impossible for Lin Ze to change it.

"Get up, I believe you already know the reason why I called you here this time. Lin Ze lightly shifted his right hand, motioned for them to get up, and then said.

"Yes, adults, little people know. One of the craftsmen replied.

This is an old man with a vicissitudes of life, who definitely looks over sixty years old, and perhaps it is because of his age that he is able to speak on behalf of others.

"That's good, old man, you come and see these drawings, can you make the things on the drawings?" Lin Ze took out a few drawings and handed them to the old craftsman in front of him.

In order to avoid the old craftsmen who are not literate, and in order to be more concise and clear, Lin Ze directly divided the water press into several parts and drew them in detail, concise and clear, without any text explanation.

"Yes, sir. The old craftsman quickly took the drawings in Lin Ze's hand, and then, with the other craftsmen on the side, began to look at them carefully.

This check was about five minutes, and Lin Ze didn't bother them at all in the middle, and let the old craftsman discuss it on the side.

Soon, the old craftsman finished discussing with them.

"My lord, we have already seen that this thing you drew is called a hydraulic press, and there is not much difficulty in making it, but there is one thing in it that we cannot make, and that is called a living ........ , Oh, piston stuff, please forgive me!"

The old craftsman said this in fear, according to the style of the officials he had seen before, he now said that if he couldn't make this thing, he would definitely be cleaned up fiercely, and even lose his life for it.

If it were the officials in the past, the old craftsman would not have said this clearly, he would go first, and then ask the officials to prepare some extremely precious or extremely difficult to find materials.

In this way, after seeing such trouble as making this thing, this official subconsciously didn't want to make it, and in the end, it would be gone.

However, this time, the old craftsman didn't want to fool Lin Ze like this.

Lin Ze recruited a large number of homeless people, which directly gave countless homeless people a way out, and the old craftsman's family was also rescued by Lin Ze in this way, so Lin Ze was the benefactor of the old craftsman's family, and the old craftsman didn't want to deceive him about his benefactor.

Moreover, the old craftsman had also heard some things about Lin Ze and knew that Lin Ze was not an unreasonable official, so the old craftsman would be so bold and tell the truth directly.

"Oh, that's it, don't worry, I'll just give you the materials to make the pistons when the time comes, don't worry. Lin Ze said with a smile.

The best material for manufacturing pistons is rubber, where will there be such materials on the Shenzhou continent, as for replacing them with some dense cloth and the like, although it is also possible, but it is far from the practicality of rubber, and the piston made of cloth will not take long to need to be replaced, and the quality is not as good as that of rubber.

"Thank you, sir, in that case, there will be no problem at all in making this water press. The old craftsman said happily that the problem of the piston was solved, and other things were really not a problem for them.

"Hehe, that's fine, old man, if there are any problems, let's talk about them together, and I'll solve them together." Lin Ze said mildly.

Maybe for other officials in feudal society, they look down on such ordinary craftsmen in their hearts, but for Lin Ze, these experienced old craftsmen are rare treasures, so his tone is unprecedentedly gentle, and his attitude is extremely sincere.

These experienced craftsmen are a pair of advantageous wings for him to be strong in the future.

"My lord, there is indeed another problem here, because some sealing chambers need to be made, so the amount of money consumed will not be small. The old craftsman looked at Lin Ze with a worried face and said.

"Oh!" Lin Ze's face did not change at all, money is really nothing to him, how much he wants, how much.

However, of course, Lin Ze wouldn't say anything like this, so he asked again: "Old man, how much money do you estimate it will cost?"

The old craftsman carefully calculated for a while in his heart, and then said: "If it is an ordinary sealed jar, it will cost only a gold coin. It's just that the requirements for pressurized water to remember the sealed jar are very high, therefore, the materials used are very precious, I estimate that even the materials and labor costs are calculated together, and it will cost nearly ten gold coins to build a water press. ”

After saying this, the old craftsman's voice lowered, as a commoner, he knew very well the value of ten gold coins....................
