The booming era begins with the director of the Propaganda Department!

Chapter 340 Second Round!!
In fact, Tong Luoyang was not the first person to study water turbine pumps. In other words, before and at the same time as him, there had always been a large number of people studying this topic.

foreign,

As early as 1908, in order to solve the problem of using the Murghab River for irrigation, the Russian Federation had the Rizh Factory in Pilwitz manufacture a turbine-pump unit for water lifting and irrigation.

The lift of this machine can reach 8.5 meters and the flow rate can reach 1.45 cubic meters per second.

In 1921, Lavachik proposed a novel structure for miniaturizing this unit and named it the pressure rotary converter. Thus, the water turbine pump was born.

Domestically,

In the winter of 1938, before liberation,
Cao Ruizhi and other experts from the Sichuan Provincial Water Conservancy Bureau began to develop the water turbine pump. They tried to directly connect the water turbine to the pump and submerge them in water to work.

In 1939, my country's first wooden model of a water turbine was born in Taoziyuan, Santai County, Sichuan Province.

after liberation,
After the water pump factory built in my country was put into production in 1952, there have been factories that have been re-inventing water turbine pumps.

Experiments have been conducted in rural areas of some southern regions, and some results have been achieved. However, in the north, research on water turbine pumps is relatively scarce.

This is mainly because the working principle of the water turbine pump is not very suitable for the north.

The working principle of the water turbine pump is actually very simple, which is to connect the coaxial water pump (upper part) and the turbine (lower part) together.

Then install them where there is a water level difference.

The turbine pump must be completely submerged in water because it uses the energy of water flow as its power.

When water from a high place falls, it impacts the water turbine below to rotate, and at the same time drives the water pump impeller on the same axis to rotate, thereby pumping water from a low place to a high place for irrigation.

The turbine pumps currently on the market and produced by those pump factories require that the water level difference between the upper and lower parts must be more than 1.2 meters. In theory, the greater the water level difference, the greater the role of the turbine pump.

Rice is mostly grown in the south, and rice cannot live without water, so water turbine pumps are widely used.

However, the north mainly grows wheat, millet and corn. These crops do not need to be soaked in water and only need to be irrigated a few times in each planting cycle.

Moreover, there is little water in the north, and most rural areas have built reservoirs and used them in combination with canals.

Needless to say, when water resources are abundant, once the reservoir is opened, a large amount of water will flow into the farmland along the canal, and there is no need for water pumps at all.

During most of the drought periods, the water level in the reservoir does not reach the level required to use the turbine pump, so it cannot be used even if we want to.

This is the essential difference between the water turbine pump designed by Tong Luoyang and other water turbine pumps on the market.

He placed the water pump and turbine of the water wheel pump on the same horizontal line, and after some modifications, he was able to achieve water lifting even without a water level difference.

In theory,
As long as the water level in the reservoir, river or stream can submerge the turbine pump, it can pump water. The lift can reach more than 2.32 meters and the flow rate can reach cubic meters per second.

"The lift is too short and the flow rate is not large." Tong Luoyang said in a deep voice, "Maybe my level is still not good enough..."

Zhang Shenfei retorted: "Don't underestimate yourself, Luoyang.

Although the lift and flow rate of the water turbine pump you designed are not particularly large, it has the advantage of not requiring a water level difference. When used in the north, it can outperform almost all southern water turbine pumps on the market.

Not to mention that it doesn’t require electricity or oil, and is easy to maintain… These are extremely important to the north. If you ask me, you are really great.”

Tong Luoyang was still struggling, with a bit of frustration in his tone: "The drought is so serious now, I am really anxious... I really want to develop a perfect product to solve this problem."

At first, his idea was much more perfect than the completed water turbine pump, but when he put it into practice, he found that he could only achieve the current level...

Thinking back to when he went back to his hometown during the Spring Festival and saw the situation in the commune and the appearance of the elders and fellow villagers, he blamed himself for being useless countless times in his heart.

There are tens of thousands of Ande Guangsha, sheltering the world with joy.

"How can you become fat in one bite?" Zhang Shenfei knew what Tong Luoyang was thinking. But now he could only comfort him.

“If your water turbine pump can be put into use, it will solve the irrigation problem in some areas.

Even if the grain output can only be increased by 0.01 percent, as long as the base is large enough, a lot of grain production can be increased.

It can provide food and clothing for tens of thousands, or even one hundred thousand, two hundred thousand, or three hundred thousand people.”

“So Comrade Tong Luoyang, stop worrying about how, maybe, what if, and don’t fantasize about being an omnipotent savior.

We don’t have that much energy, we can only do what we can do, this is the most important thing! ! ”

"After the experiment is passed the day after tomorrow, and then the second round of experiments, if this water turbine pump can be successfully put into production, your talent will be noticed, and then there will naturally be factories that appreciate it, and you can continue your research and benefit more people."

Zhang Shenfei said this not to comfort Tong Luoyang. The area currently affected mainly by the drought is the northern region.

He had seen the water turbine pump designed by Tong Luoyang, which was only a little over 30 centimeters high. Such a product was undoubtedly extremely suitable for the current arid northern region.

And as long as this water turbine pump is really useful, he will naturally help contact the factory, put it into production, and put it into use...

As he just said, even if it can only help 100,000 or 200,000 people, it would be good.

After his advice, Tong Luoyang cheered up and started checking the drawings again.

This went on until late at night, when Zhang Shenfei was about to fall asleep.

He finalized all the details and looked at Zhang Shenfei lying on the bed.

"Some parts need to be re-welded. I'll take it apart and go to the Red Star Steel Mill." He said while writing and drawing.

He originally didn't know anyone at the Red Star Steel Rolling Mill. It was only through Zhang Shenfei's introduction that he was able to go in and out frequently and seek help from the welders and fitters.

"Do you need me to go with you?"

"No need, I'm getting old, and the doormen, Mr. Qin and Mr. Dong, already know me..."

"Okay, then feel free to come to me if you need any help. I'm going to sleep first." Zhang Shenfei said, wrapped himself in the quilt and closed his eyes.

A good night's sleep.

The next morning, Tong Luoyang went straight to the steel rolling mill, while Zhang Shenfei went to class. After school at noon, he heard everyone discussing that there was pot-fried tofu in the cafeteria today.

To make pot-fried tofu, you need to cut the tofu into big pieces and then fry it in oil.

In this age when everyone is poor, it is very popular among college students.

At this moment, everyone was discussing, and then they rushed to the cafeteria together.

Zhang Shenfei also followed suit and opened the drawer, taking out an aluminum lunch box.

Since leaving the steel mill, without Zhang Cuihua, there was no one to keep and wash his lunch boxes.

Although he was dating Lou Xiao'e and they met often, Lou Xiao'e was not the kind of person who would help him do these things.

Helplessly, Zhang Shenfei could only do it himself. Thinking about it, he felt a little sad.

Zhang Shenfei left the teaching building carrying his lunch box, greeting and chatting with people he knew along the way, wasting a lot of time.

When I walked quickly to the dining hall, I saw that there was already a long queue at the B-dish window selling pot-fried tofu.

Just as he was struggling to get to the end of the line, he heard Lou Xiaoe's crisp voice coming from the front. "Zhang Shenfei, Zhang Shenfei, come quickly and get in front of me."

Ah, this...

Zhang Shenfei inexplicably felt that this was a bit familiar. Why did it seem so familiar? ? ?

Cuihua???
He touched his nose, ignored the eager looks from the people queuing behind Lou Xiao'e, and quickly squeezed into the queue.

Lou Xiao'e ordered a dish of cabbage and pork, a portion of shredded potatoes, and a steamed bun made from two kinds of flour.

Zhang Shenfei ordered a serving of pot-tart tofu, a portion of radish stewed with vermicelli, and two steamed buns.

The two of them carried their lunch boxes and walked out of the cafeteria.

Although there are tables in the dining hall, there are no stools.

Moreover, during peak meal times, every table is packed with people, and some people who don’t have a seat will even stand aside and wait for others to finish eating so that they can take their seat.

In such an atmosphere, people who have seats can only stand and eat voraciously, finishing their meals quickly to make room for the people behind them, and have no intention of talking at all.

So people like Zhang Shenfei and Lou Xiaoe who have a partner would usually bring their meals out.

Find a secluded place by the lake or in the woods, snuggle together, eat and chat about couple's little things.

The two men came to the old base in the grove, and Zhang Shenfei skillfully took out a piece of waste newspaper from his pocket and spread it out.

Put the lunch boxes on the ground, each person took a steamed bun, and ate while chatting.

When he learned that if Tong Luoyang's water turbine pump could be successfully tested at the Yenching University Farm,
When they were going to Fangshan to conduct a second experiment at Zhang Shenfei's uncle's commune, Lou Xiao'e enthusiastically asked to go along.

"We are going to do some serious business. Why are you going there?" Zhang Shenfei said, and picked up a piece of cabbage leaf from Lou Xiao'e's lunch box and stuffed it into his mouth.

Seeing this, Lou Xiao'e picked up all the cabbage leaves in the lunch box and gave them to him.

"I just want to go over and take a look. I've never been to the countryside." Lou Xiao'e said this with a hint of embarrassment in her tone.

She grew up in Beijing.
My family was well off. When I was a child, I went to Shanghai, Guangdong Province, and even international metropolises like Hong Kong with my parents.

However, I have never been to the nearby rural areas such as Fangshan, Fengtai, Changping, etc.

This is obviously inappropriate and even incorrect in this era. She only dared to tell the truth in front of Zhang Shenfei. If she were in front of others, she would not even dare to mention it.

Even in the dormitory, she never dared to mention her family background.

She tried to match her average classmates in terms of food, clothing, housing and transportation, for fear that people would know that she was the daughter of a big capitalist.

These were the repeated instructions given to Lou Xiao'e by her father Lou Zhenhua when she was admitted to Yenching University.

In the beginning,
Lou Xiao'e always felt that her parents were worrying too much.

But as the current domestic environment becomes more and more stringent, she can't help but begin to admire her father's foresight.

This time, she kept pestering Zhang Shenfei to go to Fangshan together. On the one hand, it was because she wanted to spend more time with him, and on the other hand, she really wanted to see what the countryside was like.

Zhang Shenfei couldn't persuade her and finally had to agree.

When he returned to the dormitory after school in the afternoon, Tong Luoyang told Zhang Shenfei that he had brought the machine back from the steel mill.

"The places that needed to be sawed and re-welded have been done, and the welding is perfect. We can start the experiment at the school farm early tomorrow morning. If all goes well, we will set off for Fangshan the day after tomorrow!!!" The young man seemed a little excited, with his nose and cheeks a little red.

"Luoyang, you're great. If you succeed in designing the water pump this time, we brothers will pool our money to treat you to a meal!!!" Xu Shanghai joked.

"That's right, brothers must represent the country and the people, thank you!!!" Zhu Chongqing was even more exaggerated and was about to bow directly.

"I'm so angry. How come such an awesome design isn't mine?" another roommate also shouted exaggeratedly.

Tong Luoyang felt a little embarrassed by the teasing and waved his hands quickly: "Don't, don't say that... I just modified the original water turbine pump... You guys are exaggerating..."

Why do you say that? It seems like he is even more powerful than Einstein?

"What's wrong with modification? As long as it is useful, it's a good thing!!!" Zhu Chongqing shouted.

"That's right, the classmates are all optimistic about you, Tong Luoyang, just go for it boldly!!!"

"Stop talking... I... oh..."

After more than a year of living here, everyone has realized the importance of water to agriculture.

Naturally, everyone looked up to Tong Luoyang, who designed the water turbine pump.

Such a conversation,
Ever since Tong Luoyang started designing water turbine pumps, he had no idea how many times this had happened in the dormitory.

Only a down-to-earth person like Tong Luoyang would still feel embarrassed after so many times.
Zhang Shenfei was laughing as he watched from the side. Seeing that Tong Luoyang was so embarrassed that he couldn't bear it any longer, he came out to help him out and told everyone to stop talking and go to bed quickly.

After the experiment at Yenching University Farm was successfully completed, Zhang Shenfei and his team asked for leave from the school, carried the water turbine pump and prepared to set off for Fangshan.

In addition to Tong Luoyang, Zhang Shenfei and Lou Xiaoe, there were also two students from the Department of Mathematics and Physics.
They all provided assistance to Tong Luoyang's water turbine pump.

The group first took a bus from Sijiu City, then arrived at Fangshan, and stood on the roadside feeling worried.

Then they heard a tinkling sound, and when they turned around, they saw a tall horse with bells, pulling a carriage, which stopped behind them.

On the carriage,
Qian Tiezhu grinned at Zhang Shenfei and said, "Da Fei, where are you going???"

"Brother Zhuzi, we are going to your commune. We were just wondering how to get up the mountain, and we happened to meet you..."

After saying this, he waved his hand and signaled everyone to get on the carriage.

But it was the first time for several of them to meet Qian Tiezhu, and they were embarrassed to get in the car until he gave the order.

"Don't just stand there, get in the car quickly, this is my cousin."

Well, with Zhang Shenfei's words in mind, several people climbed onto the carriage swiftly.

Tong Luoyang was finally able to put down the heavy backpack containing the water turbine pump and rubbed his sore shoulders.

Seeing that they were seated, Qian Tiezhu moved to the side to make room for Zhang Shenfei, then cracked the whip and the carriage began to move forward steadily.

"Brother Zhuzi, why are you in town?"

"Help the commune do something." Qian Tiezhu turned his head and looked at Zhang Shenfei and asked, "What about you? What are you going to do in our commune???"

They are obviously a group of students. Why are they going up the mountain instead of going to school? ? ?

Zhang Shenfei then told him about the water turbine pump.

Qian Tiezhu turned around excitedly and looked at the backpack next to Tong Luoyang.
