Chapter 182 Snowmobile (First Update)

"The parts are almost there, mainly some parts need to be processed manually." Liu Hai was talking about the tracks on the back of the snowmobile, which are not finished yet.

The tracks of modern snowmobiles are made of composite materials, but now they only use rubber-added steel wires, which are processed by themselves from rubber skins, just like retreading tires in a small workshop of Pakistan Railway.

Therefore, the progress is quite slow. After the samples come out, the tire factory can produce special tracks. Now that the samples have not been produced, it is impossible for the rubber factory to manufacture them specially for you.

Besides, I don’t want to owe any favors to my bangs, so let alone planning it, I’ll make it by hand in the maintenance department whenever I can. Although the service life may not be ideal, as long as the sample is usable, it’s fine.

"Some of the motorcycle tests on the plateau were not very ideal. In some high-altitude areas, it was said that the gasoline froze."

"There's not much of a problem with power."

"The service life of the machine is not a big problem." Sun Aiguo said another thing.

When Liu Hai heard this, he nodded. This is the benefit of the experiment. When people drive in Big Brother's place in the future, antifreeze is added to the gasoline. Otherwise, in Big Brother's environment, it is not a problem for gasoline to solidify. Many supermarkets over there have For sale.

Liu Hai was moved. Teachers could be involved in this project. He knew the rough formula and there were not many equipment used for the test.

"Let me ask the teacher about this." Liu Hai started riding motorcycles to replenish materials on the plateau. Many places there are not suitable for motorcycles in winter, but there are always a few months where they are suitable.

Motorcycles only need a small road, but cars and trucks require too much road investment.

It’s not that Liu Hai never thought of building a helicopter. Firstly, it was too late. Secondly, the country did not have the ability to produce high-end weapons and equipment. Thirdly, it would be watched by the two major social leaders. Fourthly, it would be copying Big Brother. The helicopter is useless on the plateau.

Black Hawk helicopters can be used in plateaus. Big Brother's stuff is really not suitable. The engine used in helicopters now is a radial piston engine. Modern ones use turbine engines. Turbine engines are suitable for high altitude and high temperature environments.

Even if Liu Hai makes it, he probably won't be willing to part with the equipment, and what can I say, the third brother doesn't need a helicopter, he just needs more supplies.

"Well, it's best if we can solve it." Sun Aiguo just mentioned it. Sun Aiguo's knowledge about bangs is beyond description. Look at this office. There are many tomes in Russian, English and German. , Chinese...tsk tsk.

"Can you build that one-thousand-ton hydraulic press?" Sun Aiguo almost gave himself a slap in the face, but why did he express his thoughts?

When Liu Hai heard this, he said: "It's possible. There is no casting press, so we need the cooperation of the opposite steel rolling mill. Some parts can be forged first and processed twice later, but it's a little more troublesome."

"What's the trouble? No trouble, no trouble." Sun Aiguo understood what Liu Hai said. As for trouble? Why is there any trouble? The steel rolling mill is basically supporting us now. Although it is not direct, most of the products produced end up at the motorcycle factory.

Motorcycles require a lot of steel plates, because there is no plastic now, and all parts are basically metal. Tricycle carriages, cabs, etc., and bangs will still need steel when they come out with four wheels.

"We still need to find a way to get a casting press." Liu Hai said.

The technical difficulty of the casting press is not too high. The key to the casting press is to ensure the pressure during casting. Liu Hai thought about it. If the technology is not good enough, materials can be used.

"This seems difficult to handle."

"Just wait and see, I still have a lot of things to do." Liu Hai has no choice but to learn the technique step by step.

"That's right, you start with the single-cylinder diesel engine. The higher-ups were originally planning to introduce the single-cylinder diesel engine from Little Book. Now you're doing it here. The higher-ups are not in a hurry for the time being." Sun Aiguo said.

Liu Hai knew that the single-cylinder diesel engine of the walking tractor was introduced from Xiaoben, probably this year.

"Yeah." Liu Hai knew that the introduction of technology now requires the exchange of materials or money. These are workers and farmers who have worked hard. If you use some technology yourself, these people will pay less.

I don’t know how to make the bangs for a walking tractor, but when the 25-horsepower diesel engine is produced, I will give them the drawings and let Li Dali and the others make a single-cylinder diesel engine for the walking tractor. After the technology is completed, they will be sent to other factories to make...

Sun Aiguo walked around for a while, then asked Li Dali and the others. After knowing that the snowmobile was getting closer, he left with satisfaction.

Li Dali's three-person snowmobile is almost there, and Liu Hai's side is almost the same. In fact, the simple drawings are not complicated. The main thing is that Liu Hai is testing new materials in the laboratory.

This time, Liu Hai pretended to fail dozens of times, all of which were recorded, before succeeding.

Otherwise, the bangs can be taken out in three to five days.

The snowmobile has a sled on the front and a track on the back. The 250 engine is mainly used to transport people and cargo, and is much larger than modern recreational models.

After all, it is for military use. In winter, it is used to deliver supplies to the outpost, run liaisons, patrol, etc., so the load capacity is larger.

Then we face another problem, that is, gasoline antifreeze. The freezing point of gasoline is between -40 and -120 degrees. Although -40 degrees does not necessarily solidify, it will reduce fluidity.

The higher the octane number in gasoline, the lower the freezing point. The freezing point of octane is -57 degrees.

Alcohols, ethers, or oil-soluble film-forming agents are mainly added to gasoline to prevent the carburetor of gasoline engines from clogging.

Watching Li Dali and three people assembling snowmobiles, Liu Hai felt that there were few people in the maintenance department, but the factory director didn't add anyone in, so there was nothing he could do.

Moreover, Liu Hai feels that he is not very suitable to be a manager and is more suitable to be a researcher.

Liu Hai moved his mouth, Li Dali and the other three took action. This snowmobile could pull a sledge in the future, so a hook-like design was designed at the back, and the overall frame was also strengthened.

Li Dali and the other three were very happy to talk about bangs and do it themselves, which proved that the leader valued them.

"Section Chief." After Li Dali and the others finished assembling, he looked at the green snowmobile in front of him, waiting for Liu Hai's next order.

"Go and report to the factory director." Liu Hai asked Li Dali to report.

After Li Dali went to report, Sun Aiguo came. It is now the end of July, and there are many places where it snows in October in the Northeast. It is just right to make a batch for testing.

"Is this a snowmobile?" Sun Aiguo looked at the motorcycle, which was completely different from what he usually saw.

"Uh-huh."

"How to test this?"

"Find a piece of sand, but it's just a small test."

"That's okay. Let's get a batch of samples out first."

"Director, shouldn't we leave this to others?"

"Xiao Liu, this is related to the reputation of our factory. Let's make a batch of samples and test them without any problems. If other factories have manufacturing problems later, it will be none of our business. We will take out the technical prototypes now. When the time comes, Some guys can't do it right and say we have a problem." The factory director patiently explained to Liu Hai the secrets involved. Once a problem occurs, some people don't look for their own problems, but look for others. Sun Aiguo cannot bear this responsibility. Sorry for the factory name.
