The whole family travels through time and space, and the three of them struggle together

Chapter 112 Hand Water Pump

"What unconventional ways?" Chen Xiuying also became interested and asked.

Seeing that Qing'er didn't come in and there were only the three of them in the room, Zhou Sisi took a piece of paper and quickly drew a snake on it, and then drew a line on the snake's head and tail.

"Catch a snake, remove its head and tail, and the problem is solved, right?

If you want a thick tube, catch a big snake, and if you want a thin tube, catch a small snake!" She raised her eyebrows.

Chen Xiuying was startled by this and retorted casually, "Don't listen to her! It's terrifying! How many snakes do you have to use just to apply the medicine? That hose, if it can't be made of rubber, just make it out of iron!"

Zhou Dajiang felt as if he had grasped something, but also as if he hadn't grasped it, so he grabbed Chen Xiuying's arm and said, "What did you just say? Say it again!"

Chen Xiuying was startled by him and asked in confusion, "He didn't say anything? He just said if there's no rubber, then make it out of iron!"

Zhou Dajiang caught on this time, "Have you ever seen an iron hose?"

Chen Xiuying rolled her eyes. "I've never seen iron ones, but I've seen stainless steel ones. Isn't that the shower head pipe in our shower?"

Zhou Dajiang slapped his head and said, "That's right! Why didn't I think of this? I was just chewing rubber and plastic there."

He excitedly held up Chen Xiuying's face and gave her a big kiss. "Wife, you are really my lucky star!"

Seeing this, Zhou Sisi quickly covered her eyes and protested, "You two should pay attention to your appearance!"

Chen Xiuying also let him kiss her until her face turned red, and asked him: "Do you want to make stainless steel pipes?"

Zhou Dajiang shook his head. "Stainless steel pipes can't be made. Without chromium and nickel, it's impossible for the time being."

Chen Xiuying was puzzled. "Then why are you so excited?"

"I want to make a bellows, like the ones in our shower heads."

Chen Xiuying thought for a moment, "That one is molded in one piece. Are you sure you can do it?"

Zhou Dajiang explained, "It's not exactly the same. Our technology is backward now and we can't reach that level."

"What kind of bellows?" Chen Xiuying couldn't imagine.

Zhou Sisi clapped her hands and said, "I see. Dad wants to make a corrugated pipe similar to a sewer pipe, right?"

"That's right, you are worthy of being my daughter. Your imagination is better than your mother's." After Zhou Dajiang said this, he ran away with the drawings he had drawn earlier.

Chen Xiuying, who was implied, could only grit her teeth and say, "Wait until you come back, and see how I'll deal with you."

After Zhou Dajiang ran out, he looked at the sky and thought, "Well, they should still be there at this time."

So I went to the processing plant with the drawings in my pocket.

Everyone was indeed busy. Xue Jin saw him come in and jokingly said, "Busy man, are you not busy today?"

Zhou Dajiang also replied in a pretentious tone, "Well! I'm not busy anymore. I came to inspect your work today and give you some goodies!"

Hearing that there was something good, the other two people, Xue Ren and Ma Lin, also gathered over and asked, "What good stuff?"

Zhou Dajiang then took out the blueprint and said, "Call the technical backbones and let's go to the conference room for a meeting!"

Since moving to the new factory, at Zhou Dajiang's strong request, a conference room was prepared for their technical staff.

It is called a conference room, but in fact there is nothing inside except a long table with pens and paper on it and ten chairs.

So, Carpenter Tian, ​​Zhou Dahe and Zhou Dahai were also called over.

Seeing that everyone was present, Zhou Dajiang spread out the blueprints on the table and then said, "I'm here today to make three things."

Then he picked up a drawing and looked at everyone, "Let's start with the simple one. This is a manual water pump. I drew it as a schematic diagram without marking the dimensions. Just look at the pattern. I'll come back later."

He looked at Carpenter Tian and said, "You and Zhou Dahai should complete this drawing." He couldn't do it all by himself. What would he do when he went to the provincial capital next year?

Zhou Dahai didn't expect that he would be involved in this matter. He quickly waved his hand and said, "I can't do this."

Zhou Dajiang: "It's quite simple, just treat it as practice. Before, you said you couldn't host, but didn't you host it quite well during the Chinese New Year?"

When the others heard this, Zhou Dahe, in the spirit of "betraying a friend rather than a poor one", also testified for him, "It's true, I participated in the competition, and he hosted it."

Xue Jin couldn't help but look at Zhou Dahai. He had such a talent, so he had to force him. So he decided, "Old Tian, ​​you take care of him."

Carpenter Tian nodded: "Okay!"

Zhou Dajiang continued, "At the bottom of the manual water pump is a water pipe that can reach the water surface.

Let me draw a small picture for you to see. This water pipe can be a piece of diabolo tube or an iron pipe. Then, fix it in the center of a large cylindrical base. Like this."

He drew as he spoke, "After fixing it, install a lid that can be opened upwards above the water inlet of the bamboo tube. Then, tie something slightly heavier to the front of the lid, but not too heavy, such as a small iron ball. This way, although the water below will break through the lid under the action of gravity and rush in, it will not completely overturn the lid.

This lid acts like a one-way valve. When water pours in from below, the lid is opened by the water flow. When water presses down from above, the lid automatically closes under the pressure, ensuring that water does not flow back out of the water inlet.

After he finished speaking, he waited for everyone to digest his words, and then continued, "Then, let's talk about this big cylinder. It's best to use a thicker bamboo tube, preferably as thick as a large bowl. If you don't have a bamboo tube that thick, an iron bucket of similar thickness will also work. However, be careful about iron rusting easily, so the iron sheet of the iron bucket should be thicker. It also needs to be rust-proofed and sealed."

Then, he drew a thick round cake with a round hole. Zhou Dajiang pointed at it and said, "This is the core of the water pump. I call it the plunger valve. This valve is made of a new material called 'rubber.' Of course, this rubber is still under research. If it is developed, we will use it. If not, we can use wood wrapped in oilcloth as a substitute. Let's put this aside for now."

Next, we need to drill a hole in the center of the plunger valve so that it can be fixed on the connecting rod. Then drill another hole slightly off-center in the plunger valve and install a small cover that opens upwards, which is also a one-way valve.

After the connecting rod is installed on the plunger valve, the other end is connected to the top, where the top cover and two handle brackets are installed. The connecting rod should pass through the top cover and then bend the other end into a hook shape. This hook shape can also be processed before installation.

Make another wooden handle, drill holes in the front and middle of the wooden handle, hook the connecting rod's hook on the front of the handle, and then secure it. Make another connecting shaft, place the wooden handle between the two handle brackets, and connect them together with the connecting shaft. This way, the water pressure part is completed."

He paused for a moment, letting them digest the information, before continuing, "Next, let's work on the drainage. Once all the previous connections are complete, press down on the handle. The plunger valve will slide upwards. Drill a hole in the cylinder where the plunger valve can't reach, and insert a bamboo tube. This time, use the bamboo tube as the drain. That's it. The manual pressure pump is now complete."

Then, Zhou Dajiang picked up the pen again, marked the direction of the water flow, and explained the working principle while drawing.

"When we press the handle downward, the air pressure in the cylinder is low, the small cover above the plunger valve will close, and the one-way valve at the water inlet below will open. Under the action of gravity and pressure, the water below will be pumped into the cylinder, like this.

When we lift the handle, the small cover above the plunger valve will be opened, and the one-way valve below will be closed due to the downward pressure of the water, so that the water will be pressed to the top of the plunger valve and cannot flow back.

Then, when we lift the handle again, the water above the plunger valve will move upward as the plunger valve rises, and the water below will flow into the water outlet. When we lower the handle again, the water flowing in will once again flow to the top of the plunger valve due to the drop of the plunger valve. Repeat this several times, and the water will overflow the water outlet and flow out of the bamboo tube.

After Zhou Dajiang said this, he quickly went out to find a teacup, poured himself a cup of tea and drank it.

After saying so much, oh my god, I’m so thirsty.

Then he returned to the meeting room and asked, "Does everyone understand what I just said?"
