It is quite reckless to flout the rules and regulations of production. Luo Rongchang is different from Liu Jianzhi, he didn't give Qin Zhenhua small shoes to wear, but he felt that such an apprentice really didn't know how thick the sky was, and he didn't know how many catties and taels he had.

"Why?" Qin Zhenhua turned his head and asked Luo Rongchang rhetorically.

"Does that need to be said? Electric welding is the source of ignition, and the residual oil vapor in the oil tank will ignite and explode. Luo Rongchang said: "As an apprentice, you should know these basic safety production knowledge, right?" ”

Luo Rongchang was patient, and after telling Qin Zhenhua about this, he felt that his patience was about to run out, they had no opinion on Qin Zhenhua, but they definitely didn't have a good impression of such reckless behavior.

"As repairmen, we have to use our brains." Qin Zhenhua said: "Since the fuel tank is directly welded, there will be an explosion, so we only need to change our thinking and adopt countermeasures, then we can solve the problem." ”

"Hmph, it's easy for you to say, so tell everyone how to change your strategy?"

"The fuel tank cannot be welded because there is a risk of explosion, and the first step is to clean the fuel in the tank, which is enough to use high-pressure air."

There is no need to even use anything else, local materials, there are high-pressure air cylinders inside the tank, which are used to start the tank, and then a pipe comes over and blows at the empty fuel tank, blowing away all the oil and gas in the tank!

As soon as Qin Zhenhua said, the teachers present all opened their eyes wide, right, why didn't they think of it?

The fuel tank cannot be welded, it is the basic operating procedure, but why can't it be welded, who can say? If you run out of fuel and there is still fuel vapor in it, why don't you just stuff it into a high-pressure air pipe and blow the fuel vapor out of it?

It's easy to do.

"But how can you make sure it's all blown out? Even if there is any leftover, there is still a danger of explosion! Luo Rongchang said.

How to detect it, that's a big problem, as long as there is a surplus, there is still a danger of explosion, without 100% certainty, that is absolutely not to try.

"The second step is to fill the fuel tank!" Qin Zhenhua continued: "A necessary condition for combustion, that is, there is oxygen! The tank is full of water, and even if there are oil droplets on the inner wall of the tank, there is no need to worry about burning, because there is no oxygen inside! ”

Oil droplet molecules? Zhao Guodong asked, "Do you still know about the oil drop molecule?" ”

The fuel tank cannot be welded, and it is dangerous to blow it clean, because in the long period of use, the fuel has penetrated and entered the inner wall of the tank.

This is because of the result of a gap between the molecule and the molecule.

However, the engineers present had not heard of it.

"Of course, there is a high school textbook that if you put pressure on it, the oil molecules may pass through the steel and penetrate to the other side, so blowing high-pressure air cannot absolutely guarantee safety, you must fill the tank with water, so that you can be foolproof!"

If it weren't for his father's accident, Qin Zhenhua would have been preparing for the college entrance examination, and now, his dream of going to university has been shattered, but that knowledge is forever engraved in Qin Zhenhua's memory, and he has learned to apply it.

Learn mathematics, physics and chemistry well, and don't be afraid to go all over the world, this sentence is definitely not just talking, now the domestic public, the education level is very low, although Qin Zhenhua is an apprentice in the workshop, but if you want to say that the level of education, it is definitely the highest.

"That's all right, but we can't let you do that." Zhao Guodong spoke.

He has always admired Qin Zhenhua, of course, there is Qin Zhenhua's father, but more, it is Qin Zhenhua's performance in the past few days, which is very satisfying, as a worker, you also have to use your brain, this sentence, Zhao Guodong plans to write a slogan and paste it on the wall.

This is the truth!

Brains aren't enough, though! When you encounter something to take a risk, you still can't do it, otherwise, Lao Qin is a living example!

"Why?" Qin Zhenhua asked puzzledly, he had analyzed it clearly, and he was 100% sure, did he have to toss for so long for a small fuel tank to leak oil?

"Because..."Zhao Guodong didn't continue, naturally he was afraid that you would be like your father! However, Comrade Qin's accident was to be kept secret, so he was speechless for a while.

"When I went to the countryside, in the production team, this is how I repaired the fuel tank of their tractor, and the captain of the production team dared to let me do it, hum, I really didn't expect that you people are all cowards, so self-contained, not seeking progress! In this way, you will never progress, and you will always stand still! Qin Zhenhua shook his head helplessly.

A few years ago, Qin Zhenhua responded to the call and went to the countryside, where the baby of the entire production team was a tractor, but the fuel tank of the tractor was actually leaking!

At that time, Qin Zhenhua repaired it like this, and later, the news spread that the tractors in other townships in the county had this problem, and they were all repaired by Qin Zhenhua.

"You've welded? Don't brag, do you know how to weld? Luo Rongchang said: "Without a one-year or two-year operation, it is impossible to become a qualified welder, just you?" ”

"It's just that it's a set of talks, but it's a pity." Li Changjiang is also dissatisfied with Qin Zhenhua, if you want to say that you can theorize, then let's still believe it, if you want to say that you have done it, who will believe it? Don't look at the small fuel tank, it's not easy to weld! If you don't know how to do it, if you go down with one hand, you will have to burn a bigger hole in the fuel tank!

"Don't believe me? Let's try it. Qin Zhenhua said it very easily.

Here, Qin Zhenhua is an apprentice, but when he went to the mountains and went to the countryside, Qin Zhenhua was the treasure of all the educated youth, those brigades with tractors, but he was invited to come over, and now he is not unfamiliar with the tank factory, just because he has practiced before.

Even the Yangtze River 750 in the county, Qin Zhenhua has tinkered with it.

"In that case, then, you can try!" Zhao Guodong said.

"Director Zhao, this is a violation of production regulations!" Luo Rongchang said: "In case of an accident, who will be responsible? ”

"In this way, drag this tank to the open space outside, Erzhu, you have a fire extinguisher, stand by at any time, well, I'll stay here too, it's really a problem, I'll carry it!" If it can be successful, this is a technological innovation in our workshop! ”

Hearing these words, Qin Zhenhua showed that familiar smile on his face again: "Director Zhao, since it is technological innovation, can I rely on this technological innovation to become a technical expert in our workshop?" ”

Zhao Guodong's face darkened, why do you always want to become a technical expert in the workshop, you little comrade? Is it for that honor, or for that bonus? There are so many masters, do you always want to take them? There is no precedent for an apprentice to become a technical expert!
