330 Dangerous Situations
Compared with the previous tire change training, this time there were mainly two additional technicians who controlled the oil pipe, and these two are the most "stronger and powerful" in the entire technician team.
Don’t think that the F-racing refueling pipeline is just like the small oil gun inside the gas station. The efficiency of the oil gun is, and it takes dozens of seconds to fill the fuel tank of a civilian sedan.
f The size of the fuel tank capacity of a racing car belongs to the team's confidentiality category. All teams will not disclose the fuel tank refueling of their racing cars. However, you can roughly guess the fuel tank capacity is about 30l based on the number of races and the refueling time.
For a race against time like F, it will take one or two minutes to cheer on, and there is no need to run. After all, it will take no more than two minutes to run a lap of the track!
Therefore, the F gas pipeline is all very thick high-pressure oil pipes. Once the race car is parked, the technician needs to carry the huge fuel pipeline on his shoulders. One of them connects to the oil injection port, and the other person is responsible for keeping the oil passage unobstructed.
After pressurization through the oil pump, 2 liters of fuel can be injected per second, which is far beyond the efficiency of civilian gas stations. It is precisely because the fuel pipeline is not only heavy, but also has the same impact force as a high-pressure water gun, so if there is a slight mistake in cooperation, the fuel will also be injected like a water explosion pipe.
In order to avoid such accidents as much as possible, there are two technicians on standby behind the two refueling technicians. Their function is to hold a huge 60-liter fire extinguisher and try to take remedial measures after the accident occurs.
The first time I entered the station to refuel, the maintenance team members were very serious, standing with their hands on both sides of the parking space, waiting for Zhang Yifei to enter the station.
Ahu and Chen Zhi were also standing among the technicians. This time, all the people in the 20th place were dispatched. It looked a bit crowded from the outside, so the requirements for positioning and cooperation will be higher.
"Brother Zhi, the old German man issued a training order on the first day. Isn't it a bit ahead of the way?"
"He's just this style, focus more."
Chen Zhi reminded Ah Hu, now is not the time to chat and discuss Cosell, the competition engineer has absolute authority on the track, and the maintenance team must implement the instructions. The strategy does not require a technician to consider.
"Brother Zhi, I'm actually a little nervous. It's much better to talk to you."
Faced with Chen Zhi's instructions, Ah Hu said what he said in his heart, and he did not dare to question Cosell's instructions. However, there was a lot of practice today, and he had no confidence in himself.
After all, today is not only the first time Zhang Yifei received training in the station, but also the first time they cooperated with the maintenance team. In particular, Ah Hu is younger than Zhang Yifei. A few months ago, he was still a teenager who had never seen the world. It is fake to say that he is not nervous.
"It's okay, the two of us have not changed, just the same process as before."
It is naturally impossible to control the refueling pipeline to two new technicians, so Ah Hu and Chen Zhi still changed to the left front tire without any change.
Hearing Chen Zhi's words, Ah Hu felt more at ease. After all, he performed well after entering the station dozens of times before. Now he is just doing it again, so there should be no problem.
The roar of the engine of the js5 racing car came soon, and Zhang Yifei naturally knew the danger of refueling in the station, so this time he was particularly serious and did not want any mistakes due to his own factors.
Seeing the sign in Charlie's hand, Zhang Yifei braked and accurately parked the car in the repair parking space.
Now is the last time I entered the station training today. Zhang Yifei doesn’t have to consider the wear and tear of the tires after the brakes are dead, so this time I entered the station and stopped the train, which is easier for Zhang Yifei.
Technically, the operation is simpler, but psychologically, it will be more stringent.
Zhang Yifei locked the sign with his attention and kept passing through the rearview mirror to observe the movements of the refueling technician. In this way, he immediately started the race car and left the station without wasting any milliseconds of time.
This feeling is very similar to the waiting time for a 100-meter sprint. All athletes know that they have to wait until the commander commands to start. But in fact, there are countless things like snatching up in the competition. Even at the highest level of the Olympics, you can see almost every game.
Can this be said that athletes lack psychological quality or lack of concentration?
Of course the answer is no. If you can stand on the Olympic sprint track, the athlete's level cannot be described as one in a million, but rather as one in a million!
The reason why there is a rush to start is because of the high concentration of attention and the advantage of the millisecond level. Any turbulence will make the athletes instinctively rush out, leading to a rush to start.
The same is true for the car leaving the station. The driver also knows that he must wait until the oil pipe is unplugged and the sign prompts the gear to be hung before the exit can be started.
But in fact, in order to save this reaction time, many drivers directly mount the gear and press the clutch and wait. They may see the sign shaking for a while, and subconsciously think that it will flip, and kick the accelerator and kick it out.
In addition, the "lollipop man" also needs to buy time for the driver. The gas technician may have just pulled out the oil pipe, and the sign in his hand has been flipped, causing the driver to leave the station early.
These two situations are the main causes of the repair station refueling accident.
After parking, the jack lifted the car and all the technicians surrounded it, and they divided their labor like precision machinery.
But at this time, an accident happened. After Ah Hu took off the left front tire, he retreated and gave way and followed Chen Zhi, who was about to replace the new tire, and the two collided directly.
This collision prevented Ah Hu from holding the tire in his hand, and fell to the ground and rolled to the gas technician on the back.
fThe racing tires are lighter than ordinary car tires because they do not have an inner layer of steel wire, but with the aluminum-magnesium alloy wheel hub, it still has a bit of weight when hitting it.
More importantly, the gas technician was carrying the heavy gas pipe on his shoulders and never expected that something would hit his leg. So the collision directly made his body shake violently, and the gas pipe was about to fall off from the oil injection port.
This was the first time that the track was fully entered into the station, and the members of the P room were also closely watching the situation of entering the station.
Unexpectedly, this unexpected situation would occur. If the refueling pipeline falls off from the oil injection port, up to 2 liters of gasoline per second will be instantly poured on everyone in the parking space, including driver Zhang Yifei.
Moreover, the JS5 racing car has been running on the track for almost two hours, and the engine temperature is already terrible. As long as gasoline drips on it, it will detonate like a bomb.
