doomsday survival

Chapter 375 Steam Age ([-])

In fact, during the process of developing the steam engine, Shi Jian had already considered the issue of sealing.

The material with the best sealing performance is of course rubber, but now the rubber industry has long since ceased to exist, and the Northeast is not a natural rubber production area, so naturally it has become a big problem.

Fortunately, there is also a bicycle factory in the industrial park, and there is still a lot of stock in the warehouse. Shi Jian used these bicycles to assemble many red deer carriages, and they are still in use.

The inner tubes of bicycles are rubber products, and there are many stocks in the raw material warehouse. Shi Jian used these rubbers to make some sealing rings by hand to seal the steam engine.

But the steam pipe is not good, the pipes are connected by threads, and the rubber is too thick, there is no way to add it.Shi Jian believes that the threads are all processed by machine tools, and there will be no problem with the fit.Unexpectedly, it was not what I thought at all, and it eventually led to today's result.

Fortunately, there was no steam leak from the steam engine, otherwise the high-pressure steam inside would be extremely hot, and if it sprayed on people, it would be a trivial matter to lose skin and flesh, and even kill people.

"Scientific research really cannot tolerate a little sloppy." Shi Jian sighed in his heart, and began to look for a solution to the problem.

Even if the pipe is not sealed, it will cause steam leakage. In mild cases, the power of the steam engine will be too low. In severe cases, the pipes will burst, causing casualties.

Therefore, before solving the sealing of the pipeline, Shi Jian was not going to test the engine again, and the first test engine of the steam engine was suspended just like that.

Seeing that success was imminent, but this mistake suddenly appeared, Shi Jian was naturally unwilling.In fact, not only himself, but also everyone present, everyone did not leave, thinking about how to solve this problem in their hearts.

"Why don't we use glue." Feng Kuang suggested.

Shi Jian thought for a while and said, "If you use glue, it's okay in the short term, but if it is eroded by water vapor for a long time, the glue will definitely break."

Feng Kuang thought that this was indeed the case, so he thought again.

"Mr. Shi, we might as well weld these pipes to death." Meizi said from the side.

"No, if it is welded to death, it will be troublesome to replace the pipe if there is a problem. Moreover, we use cast iron, so it would be a waste to replace the steel pipe without welding." Shi Jian vetoed again.

"Is the rosin okay?" Xia Qianhe also came up with an idea.

Shi Jian thought about it carefully, then shook his head and said, "It still doesn't work. Rosin has a certain weak acidity, which will corrode iron products, and it is relatively brittle, so it is not suitable."

Seeing that so many suggestions were inappropriate, everyone didn't know what to do for a while, and the scene fell silent immediately.

"Mr. Shi, why don't I ask Lao Shi to come over and ask." Gao Shanhe said.Then he explained, "He's a former construction worker, and he's also installed plumbing, so maybe he can figure it out."

Shi Jian knew that what Gao Shanhe was talking about was Shi Zhuangzhi, although he didn't have any hope, but he couldn't dispel Gao Shanhe's enthusiasm, so he agreed, saying: "Where you use Gao Lao, you go, let them run for a while. gone."

When Wang Gang heard what Shi Jian said, he immediately sent a worker to find Shi Zhuangzhi.

Shi Zhuangzhi walked in without much effort, and after hearing the whole story, he smiled and said, "This problem is simple, and it will be settled soon."

Seeing that Shi Zhuangzhi was so confident, Shi Jian humbly asked for advice: "Mr. Shi, I don't know what items are needed. I'll ask someone to prepare them right away."

"Get some hemp rope and some oil, and it will be done soon." Shi Zhuangzhi said confidently.

"Hemp rope?" Shi Jian froze for a moment, feeling a little unreliable in his heart, but he still asked people to prepare what Shi Zhuangzhi needed.

These two things are not difficult to find. Before Shi Jian came, the Changbai tribe had grown flax, and oil was even more abundant.

Soon, a piece of hemp rope and an oil bottle were brought over.Shi Zhuangzhi took the hemp ropes, unraveled them with his hands, and soaked the loose hemp ropes in oil for a while.

Shi Zhuangzhi took out the oil-soaked twine, looked at it, nodded in satisfaction, and said, "Unscrew the pipe."

The corner of Shi Jian's mouth twitched a little, and while asking Meizi to take someone to separate all the pipes, he asked, "Old Shi, will this work?"

Shi Zhuangzhi chuckled and said, "Mr. Shi, don't think you can develop a steam engine, but when it comes to An Shuinuan, you are definitely not as good as me. Don't worry, I will definitely do it if I say it can be done, at least we have to try it, yes No?"

As soon as he spoke, the pipe had been unscrewed.Shi Zhuangzhi walked over, tightly wrapped the thread of the pipe several times with twine, and then re-screwed the pipe.

Leaving aside other things for the time being, just look at Shi Zhuangzhi's method, obviously he has done this job before, which made Shi Jian feel at ease.

The boiler was ignited again, the water in the water tank boiled again, and the pointer of the pressure gauge continued to rise, and finally stopped.

The piston of the steam engine moves slowly at first, and as the boiler produces more and more steam, the speed of the piston becomes faster and faster.The blower is driven by the crank connecting rod mechanism, and the flame of the cupola is blown hot.

This time, no one cheered again, and everyone looked at the pipeline intently, hoping that there would be no more steam leakage.

Time passed slowly, and after an hour, there was no air leakage in the pipeline, Shi Jian finally breathed a sigh of relief: "It should be a success!"

He turned around, held Shi Zhuangzhi's backs, shook them up and down, and kept saying grateful words: "Mr. Shi, thank you so much, without you, I don't know when this steam engine will be ready." .”

Shi Zhuangzhi said with a displeased face: "Boss Shi, it seems that what you said is from your own people, why is this necessary?"

"Hehe, that's good, I won't say anything unnecessary about Mr. Shi." Shi Jian laughed.

Shi Jian did not expect that this extremely simple method would become a real solution, which made him even more lament that "a family with an old man is like a treasure".

In fact, Shi Jian didn't know that in the first half of the [-]th century, the steam engines produced at that time were sealed with hemp rope soaked in oil.Therefore, the solution to the problem does not lie in its simplicity, but in its effectiveness.

The steam engine continued to work until the end of the night, and during this period, there was no steam leakage from the pipeline.

The successful operation of the first steam engine is of great significance.Everyone knows that this marks that the Chang'an Tribe has entered the age of steam, and will develop further and further away from it.

Shi Jian also began to prepare to expand the use of the steam engine, and the first thing that came to his mind was of course power generation.
