The reason why Li Fanyu dared to solve the seepage accident in the bottom-hu Lake tunnel in such a simple and crude way is because...zxls-1911's super large pumping efficiency!

However, the pumping system of zxls-1911 is not a brand new design of Zhengxin.

So where did this design come from?

It originated from several patents from the special equipment research and development department when the Jingwei automatic hinge suction system was upgraded and transformed.

It is precisely based on the hinge suction pumping system that can blow sand and fill the sea, combined with the high-power Shanshen iiv12 engine, that the zxls-1911's abnormal pumping system is created!

In this system, it has a conveyor cylinder inner diameter of 540mm and an extra-large conveyor cylinder stroke of 4200mm.

Leng Bingbing's data may not show anything, but if you compare other products on the market, the horror of these two data will appear; the highest-end pump truck product that can be purchased on the market, namely Mitsubishi's 091d concrete pump truck, the inner diameter and stroke of the conveyor cylinder are 260mm and 1800mm respectively,

In other words, the conveyor cylinder of Zhengxin ls-1911 is exactly twice as large as the Mitsubishi 091d, and it also has a turn!

According to the previous test results of Zhengxin Power, the theoretical pumping times of zxls-1911 are low pressure 29 times/min and high pressure 19 times/min. The theoretical pumping pressure is low pressure 16.5mpa and high pressure 26mpa.

With such performance support, in theory, zxls-1911 can transport 255 cubic meters of standard concrete per hour under high pressure state. In low pressure state, this data is a terrifying 380 cubic meters!

But please be aware.

This conveying capacity refers to concrete that has been prepared and sticky as if it is stool.

If it is replaced with water, the pumping efficiency can be increased by at least three times!

According to the data given by the municipal government, the area of ​​the artificial lake is 2,198 square meters and the deepest is 6 meters. Based on the current water level, there are about 5,000 cubic meters of water and silt.

According to his calculations, even with the minimum pumping efficiency of 800 cubic meters per hour, two zxls-1911s can complete the drainage operation of 5,000 cubic meters of lake water within three hours while working at the same time.

This is Li Fanyu's courage to interfere in this matter and release the capital to empty the lake water and silt within three hours.

...

The two zxls-1911s with super large and cool appearance work at the same time, which brings visual and psychological shock to the surrounding citizens.

The two pump trucks were lying prone to the lake like some kind of steel monster crawling out of the center of the earth.

The two thick hoses placed at the bottom of the artificial lake were like monsters' mouthparts. They kept washing out the black and smelly mud and the large amount of muddy lake water from the bottom of the lake.

And the raised arm was like the tail of a poisonous scorpion. The black dragon made of two silt and lake water looked like the venom sprayed from the "tail of a poisonous scorpion" from a distance!

But this appearance alone is not enough to make people feel the changes brought by technology to industry. What really surprised people is the artificial lake surface that shines in the cold light in the winter sun!

"My mother! Look! The lake water seems to have dropped a lot!"

"Just nonsense! How long has it been to slap this time? Even if the whale comes, it won't be so fast, right?"

"You are lying to you! Look at the ice layer on the lake! The ice layer was light blue just now, which means that there is lake water under the ice surface. But look at the ice surface now, the ice surface has become white! What does white mean?"

“What does it mean?”

"It means that the water level under the lake has dropped, and it is empty under the ice!"

"Damn it! You seem to be true when you say this!"

Above the lake.

Those firefighters who received the order from Han Zhaojun and were responsible for assisting Zhengxin in the lake drainage operation were completely convinced at this moment! Standing on the front line of construction, their feelings about the two big guys by the lake were the most intuitive.

You should know that these fire trucks from the Fuzhou Fire Brigade were Steyr's latest products introduced to the Chinese market the year before yesterday. Its pumping capacity can reach up to 340 cubic meters per hour, and it is one of the best among the current fire truck pump trucks in the country.

Now, while two fire pump trucks were powered up, they were crazy about tilting the water column at the bottom of the lake to blow away the mud. However, they could intuitively see that the water level was dropping at a speed visible to the naked eye!

What does this mean?

This shows that these two pump trucks worth more than 7 million yuan are simply slack compared to those two guys by the lake in terms of pumping capabilities.

No, it's just a scumbag!

The layman watches the fun, while the insider sees the tricks.

When the two super-large pump trucks of Zhengxin started working and tilted the silt and lake water in tons of metered silt onto the diversion channel several meters above the artificial lake surface, the bosses of the construction companies standing in the distance were completely aphasia.

Swear to the lights! They have never seen a concrete pump truck with such a terrifying pumping capability!

Compared with the two big guys in front of me, the pump trucks used by my company can't be called pump trucks. They are all toys, all toys for children to play house!

The deafening sound of drainage on the artificial lake also shocked the exhibition center, which is only a few hundred meters away from here.

Many people heard the sound and saw two mechanical beasts emptying operations with an unprecedented momentum, and they came from the exhibition center to the artificial lake and stopped to watch.

Some representatives of international construction companies were even more excited when they saw the English slogans and instructions specially sprayed on the two zxls-1911s!

"Oh God! If you use this thing to build a high-rise building, how efficient will it be? Quickly! Write down the phone number above!"

"Mr. Bruce, the company that belongs to this product just now seems to have sent us a promotional brochure."

"What manual? Why didn't I pay attention to it? Is it still in your hands?"

"exist,"

"Hurry! Come and give it to me quickly, I want to take a good look at the parameters of these two cute guys!"

At this time, the news that the subway line 1 under construction under the artificial lake was leaking, and Zhengxin Group was using the products participating in the exhibition to solve the problem. Provincial TV reporters who were interviewing and recording at the exhibition center, and CCTV's second economic channel reporters also flocked to them.

In just over an hour, People's Park became the second exhibition center! There were no less than 2,000 people gathered on the periphery of the artificial lake, and the entire park was covered with water. The scene was close to the Dragon Boat Festival outing.

Just for this, Wang Mingxuan had to make a special call to the traffic police team and the law enforcement bureau and sent additional personnel to maintain order on the scene.

Under the witness of more than 2,000 people at the scene, the water and silt of the artificial lake are rapidly decreasing at a speed visible to the naked eye!

Seeing the crowds outside the field and the echo of the ethereal pumping sounds under the ice cave, Li Fanyu and Liu Qing beside him smiled.

Zhengxinzxls-1911, want to be popular!
Chapter completed!
