It is quite reckless to flout the production code, rules and regulations. Unlike Liu Jianzhi, Luo Rongchang did not give Qin Zhenhua any shoes to wear. He just felt that such an apprentice worker really didn't know the heights of the sky and the earth, and he didn't know how much he weighed.
"Why?" Qin Zhenhua turned around and asked Luo Rongchang.
"Does this need to be said? Electric welding is a source of fire. The remaining oil vapor in the fuel tank will be ignited and explode." Luo Rongchang said: "As an apprentice, you should know these basic safety production common sense, right?"
Luo Rongchang patiently finished telling Qin Zhenhua this and felt that his patience was running out. They had no problem with Qin Zhenhua, but they definitely didn't like such reckless behavior.
"As repairmen, we must use our brains." Qin Zhenhua said: "Since welding the fuel tank directly will cause an explosion, we only need to change our thinking and adopt countermeasures to solve the problem."
"Hmph, it's easy for you to say. Then tell everyone how to change the strategy?"
"The fuel tank cannot be welded because there is a risk of explosion. The first step is to clean the fuel inside the tank. For this, high-pressure air is enough."
You don't even need anything else, just use local materials. There is a high-pressure air cylinder inside the tank, which is used to start the tank. Connect a pipe to it and blow it against the empty fuel tank to blow away all the oil and gas in the tank!
As soon as Qin Zhenhua said this, all the masters present opened their eyes wide, yes, why didn't you think of that?
It is a basic operating procedure that the fuel tank cannot be welded, but why can't it be welded? Can anyone tell me? After draining the fuel, there is still fuel vapor in it. Then, insert it into a high-pressure air pipe and blow out the fuel vapor inside.
, isn’t that enough?
This can be done easily.
"But, how can you ensure that everything is blown out? Even if there is any residue left, there is still a risk of explosion!" Luo Rongchang said.
How to detect it is a big problem. As long as there is something left, there is still a risk of explosion. If you are not 100% sure, you must not try it.
"The second step is to fill the fuel tank with water!" Qin Zhenhua continued: "A necessary condition for combustion is the presence of oxygen! The fuel tank is all filled with water, even if there are oil droplets seeping out of the inner wall of the fuel tank, it will
Don’t worry about burning because there is no oxygen inside!”
Oil droplets? Zhao Guodong asked: "Do you still know about oil droplets?"
The fuel tank cannot be welded, and it is dangerous to blow it clean because the fuel has penetrated into the inner wall of the fuel tank over a long period of use.
This is because there are gaps between molecules.
However, the engineers present had never heard of it.
"Of course, it's in high school textbooks. If it's pressurized, oil molecules may pass through the steel and penetrate to the other side. Therefore, blowing high-pressure air cannot guarantee safety. The fuel tank must be filled.
Water, this way everything will be safe!"
If it hadn't been for his father's accident, Qin Zhenhua would have been preparing for the college entrance examination. Now, his dream of taking the college entrance examination has been shattered, but the knowledge will always be engraved in Qin Zhenhua's memory, and he can apply what he learned.
If you learn mathematics, physics and chemistry well, you will not be afraid of traveling all over the world. This sentence is definitely not just a saying. The current domestic public has a very low level of education. Although Qin Zhenhua is an apprentice in the workshop, in terms of education level, he is definitely the highest.
of.
"What you said is all right, but we still can't let you do this." Zhao Guodong spoke.
He has always admired Qin Zhenhua. Of course, it was because of Qin Zhenhua's father, but more importantly, Qin Zhenhua's performance in the past few days has been very satisfactory. When a worker is a worker, you must also use your brain. This sentence,
Zhao Guodong planned to write it into a slogan and post it on the wall.
This is the truth!
However, just having a brain is not enough! If you encounter something that requires 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 was 100% sure. Do you have to spend so much time just for a small oil tank leak?
"Because..." Zhao Guodong did not continue, naturally because he was afraid that you would be like your father! However, Comrade Lao Qin's accident must be kept secret, so he was speechless for a moment.
"When I went to the mountains and countryside, in the production team, I repaired the fuel tanks of their tractors in this way. The captain of the production team dared to let me do it. Huh, I didn't expect that all of you people would do it.
You are a coward, stuck in your ways and not seeking to make progress! If you do this, you will never make progress and 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. There, the treasure of the entire production team was a tractor, but the tractor's fuel tank was leaking!
At that time, Qin Zhenhua repaired it in this way. Later, when the news spread, Qin Zhenhua repaired all the tractors in other townships in the county that had this problem.
"Have you ever welded? Stop bragging, do you know how to weld?" Luo Rongchang said: "Without one or two years of operation, it is impossible to become a qualified welder, just you?"
"That's right, he talks in one way, which is a pity." Li Changjiang is also dissatisfied with Qin Zhenhua. If you say you can reason, then we will believe it. If you say you have done it, who will believe it? Don't look at Xiao Xiao
Welding a fuel tank is not easy! If someone doesn't know how to weld it, the fuel tank will have to burn a bigger hole with just one hand!
"Don't believe it? We can give it a try." Qin Zhenhua said easily.
Here, Qin Zhenhua is an apprentice worker, but when he went to the mountains and countryside, Qin Zhenhua was the treasure of all educated youths. Those brigades with tractors all invited him to come over. Now when he comes to the tank factory, he is not unfamiliar at all.
It’s just because I’ve practiced it before.
Qin Zhenhua even tinkered with the Yangtze 750 in the county.
"If that's the case, then give it a try!" Zhao Guodong said.
"Director Zhao, this is against the production regulations!" Luo Rongchang said: "If an accident occurs, who will be responsible?"
"Let's do this. Drag this tank to the open space outside. Second Pillar, you hold the fire extinguisher and be on standby at any time. Well, I'll stay here and be careful. If something goes wrong, I'll carry it! If it succeeds, this
But it’s a technological innovation in our workshop!”
Hearing these words, Qin Zhenhua's face showed that familiar smile again: "Director Zhao, since it is a technological innovation, can I rely on this technological innovation to become a technical expert in our workshop?"
Zhao Guodong's face darkened. You little comrade, why do you always want to become a technical expert in the workshop? Is it for the honor or the bonus? There are so many masters, do you always want to take them? Apprentices become technicians
