Chapter 127 Something happened in the village (first update)
PS: The title of the chapter in the last chapter is wrong. You need to wait for the editor to change it. If you can’t change it yourself, don’t blame it.

But just think about it, because it won't happen in a while.

"High-pressure explosion-proof hose, this must be available. It will be widely used in the future." Liu Hai sent Sun Aiguo away, and then sat down to read a book, thinking about it while reading.

The high-pressure explosion-proof hose mainly has several layers of mesh coatings of different materials, two layers, four layers, and six layers.

Modern use is generally two layers of nylon mesh, two layers of steel wire, or other composite materials, so that the explosion-proof hose is elastic enough and the overall product is relatively soft.

However, if all steel wires are used, the elasticity is slightly insufficient, the weight will be large, and the overall product is relatively hard.

In fact, the entire product line is not complicated. The first is a nozzle mold with a heating extrusion device to extrude the rubber particles into a tube shape. There will be a first film coating at the outlet of the nozzle, which is generally a rotating mold. A machine for weaving nets, with several posts on which steel wires or nylon threads are wound.

Then go to the next step to heat the rubber particles and the second layer of film, so you need to add a few of these in the middle of several layers.

Of course, it sounds like a long story, but in fact, it only takes a few seconds from rubber particles to finished product. The key is the temperature of the mold, the running speed of the mold, and the speed of weaving the covering net, all of which are combined.

But with this set of equipment, Liu Hai felt that he had been working alone for at least a year.

"What about the manual workshop?" Liu Hai then lowered the technical difficulty.

This belongs to the kind of workshop in Batie. This is very simple. First weave the structure of the film, and then put the film on the equipment similar to sausage filling. The sausage is the position where the rubber tube comes out. The rubber tube comes out Start covering.

This has a disadvantage, that is, only how long can be produced at a time, such as 50 meters, 30 meters, and so on.

Explosion-proof high-pressure hoses involve many industries, such as airplanes, ships, trains, various mining machinery, and various processing equipment, which is a threshold that cannot be bypassed.

Liu Hai decided to do it, because he was still young, but the 500-ton hydraulic press can only be hard-connected with seamless steel pipes for the time being.

This is to fix the motor and everything else so that there is no movement
Fortunately, the 500-ton hydraulic motor is not very static. In addition, the thickness of the rubber pad can be added to the seamless steel pipe joint to reduce vibration.

"Anyway, it's just to fool the big brother. It's not a big problem to run it for a few hours, or even ten days and a half months."

The next day, Sunday, when other people were still working overtime in the factory, Liu Hai went to Teacher Zhu's house to make up lessons.

"Brother, brother." Xiaolin saw Liu Hai coming on a motorcycle, and rushed out of the house in a flash.

Liu Hai sensiblely drove the little girl around, the little girl talked about the kindergarten, and Liu Hai echoed it.

"Teacher, this is my homework. I'll go to Petrov's place first. I'll give you the car keys. You can ride as you please." Liu Hai handed the homework to the teacher and said.

When the little girl heard this, she looked at her old father.

"Go ahead, come home for lunch." Teacher Zhu nodded.

On Petrov's side, several people gathered together when they heard Liu Hai coming. This time Liu Hai ordered some fried peanuts and some sugar from the factory canteen.

"That's great." Petrov took a big sip as soon as he came up, and said happily.

Chat while attending class.

"Petrov, is the explosion-proof high-pressure pipe complicated to manufacture?"

"This is not very complicated, the key problem is..."

"That is, the design and manufacture of the mold is the key, the running speed of each part, etc..." Several foreign teachers replied with their tongues out in a daze.

Liu Hai was studying and asked at the same time: "Petrov, you guys are talking about the rotation of the excavator, how is it connected to the machine below."

"This technology is more complicated, and it uses..."

Before noon, Petrov and the others went to sleep happily. There must be ears in this place, so Liu Hai asked about mechanical things.

I was blowing the air outside, and my body smelled of alcohol. It’s not hot in Kyoto in September. When I went back to the village tonight, Li Bing’s clothes were ready, some new and some old.

Liu Hai thinks that the current situation is very good, there are partners, men, there are people who don't want women, the more successful the man, the more women there are.

Marriage is very troublesome, so I just mess around like this, anyway, it is impossible for Wang Hongmei to marry me, and I just happen to...

"It's this child. Is it my problem or Wang Hongmei's problem?"

We had dinner at the teacher's house at noon. At five o'clock in the afternoon, Liu Hai rode a motorcycle to Li Bing's place to load a sack of things. Liu Hai went to the supply and marketing cooperative to buy some things. Although Wang Hongmei was not her lover, she was My own woman will still feel pain when she should, but I can't guarantee that there will be no problem with the other supplies.

"Feels a bit like Bao Xiaosan?" Liu Hai was riding a motorcycle and speeding on the road.

It’s fast to have a motorcycle, and Liu Hai will be home before it gets dark. This time I will take a day off and go back to the city the morning after tomorrow.

"Xiaohai, you're back." When he heard the movement of the motorcycle, the first person to come was the captain.

"What's wrong?" Liu Hai was washing the pot, when he heard this, he said.

"I don't know what it is. The chickens and ducks in the village have been harmed, and several sheep have been harmed. I told the township, and the township sent militiamen. They said it was a leopard. They guarded it for two days. If they didn't, the sheep were thrown away. It is." The captain said.

When Liu Hai heard this, he was not surprised at all. Now that the forest has been cut down, the animals at the bottom of the food chain are gone, and the only ones at the top of the food chain come to the village.

Liu Hai understood, and said, "Uncle, where did the leopard go from?"

"We've looked for it, it's on the eastern pass."

"Well, I'll go up the mountain to have a look tomorrow." Liu Hai nodded and replied.

"Come on, I'll send someone to be with you tomorrow." The captain said.

Liu Hai said, "Okay."

Wang Hongmei came at night when she heard the sound of the motorcycle. Looking at the clothes that Liu Hai brought back, she reached out to touch them and asked, "Is this for me?"

"Take it back and change it. Put the old clothes and fabrics at home outside, otherwise it will be seen by others." Liu Hai nodded and said.

"Uh-huh."

"What about you?"

"My factory over there needs to distribute clothes." Liu Hai thought, motorcycles will be put on the schedule, and three-wheeled motorcycles can be mounted. Otherwise, it would be scary to think about riding this in winter.

A breakup was better than a wedding, and they went back and forth several times. Liu Hai was recharging his energy when he suddenly heard the sound of a gong outside.

"I guess the leopard came down the mountain." Wang Hongmei said after hearing this.

"You continue to sleep." Liu Hai heard that there was a leopard, and Wang Hongmei suddenly became unhappy, and got up while talking.

Liu Hai rushed out with a rifle and a submachine gun on his back. When he came out, he found that it was already dawn, but Liu Hai did not go to see the excitement, but rushed directly to the pass.

After a quick march, I arrived at the pass. Standing on the pass, I could see torches and human voices in the village far below the mountain. Then I took out a tactical helmet, but the helmet was wrapped with a layer of camouflage cloth, and the battery was placed on the waist. Inside the bag.

"Two!" Soon Liu Hai found two shadows running from the bottom of the mountain. They looked quite big, and they were one behind the other. They were swimming leisurely. They were also holding a sheep in their mouths. The sheep's carcass was still hot. It's so clear in thermal imaging.
