With the change of unit output, the refrigerant flow rate of the water-cooled pipeline responsible for cooling the gas turbine also changes, which leads to the problem of expansion caused by large temperature difference when designing the water-cooled pipeline. Brilliance, the department responsible for designing the gas turbine cooling system, noticed this, but the department responsible for designing the lubricating oil system could not have thought of this.
As a result, the actual working hours of the unit were affected by the water cooling system, and the pre-design estimate was made. Finally, this seemingly unremarkable small mistake led to the leakage of the lubricating oil pipeline due to the shrinkage and expansion problem, which led to a great disaster.
Although the whole accident process is full of a series of coincidences and mistakes, this coincidence is absolutely accidental in industrial production. From a mathematical point of view, there is no difference between the 1% probability and the 99% probability with the passage of time or the number of times, and they are all doomed to life.
The so-called safety and reliability are all hard-burned with real money. If it weren’t for this accident, Li Yuanling wouldn’t have noticed that the power of the gas turbine changes frequently, and the water cooling pipeline and the lubricating oil pipeline could not be designed together.
Thinking that a set of core machines of gas turbine enterprises such as Rolls-Royce, Qualcomm, Pratt & Whitney and Alstom have come up with dozens of models aiming at various operating environments, it is also this kind of loss that makes the gas turbine market more classified after eating too much experience.
For example, with the experience of this explosion, Brilliance can make two new models, one is to keep the original design defects unchanged, and the output of the gas turbine is stable and normal. If the equipment makes the party change the gas turbine environment without authorization, resulting in an accident, Brilliance will not only be responsible, but also earn maintenance money.
The other is to summarize the experience and lessons and change the phase design so that the gas turbine should broaden its environment and become a so-called high-grade production …
I have been edified by my little bastard for a long time. This business is really good at it. Li Yuanling is in distress situation and thinks about the "cheat money" scheme that she just came out.
Li Yuanling is holding an accident report and lamenting that it is not easy for the "Industrial Pearl" production and research institute to start a series of running from a distance.
For more than ten seconds, Ning Wanfei was the first to rush in when the door of Li Yuanling’s office partition was slammed.
"What’s the matter? What happened? You three run full head big sweat "Yuan-ling li asked some worry.
Looking at Liang Yuan stealthily staring at the corridor outside, Ning Wanjia took a deep breath and came to Li Yuanling’s side, holding Li Yuanling’s neck and said softly, "Liang Yi is amazing. The three of us have just developed a new guide material and now we don’t know what to do."
Ps paid the debt first, and didn’t come back until midnight last night. I’m sorry for waiting for more friends.
Chapter 263 Newton Apple
"My Jia Jia is so good that you can introduce new materials by just trying." Li Yuanling smiled and took out a handkerchief and wiped Ning Wanjia’s forehead.
For Li Yuanling, a researcher who is often in contact with the frontier of scientific research, guidance is a common thing.
In nature, when the material temperature is lower than 5k, one-third of it can produce conduction phenomenon. Li Yuanling knows that the three people are trying to compare the materials of the magnetic gun wire coil these two days, so the three people are rare and strange.
"Liang Yi isn’t …" Some worry Ning Wanjia was speechless and didn’t know where to start this problem.
"Aunt Liang, the critical transition temperature of our new material is 39k, which has broken through the barrier of liquid hydrogen." Ning Wanfei, who likes martial arts, finally calmed down a lot and directly pointed out the key data.
Li Yuanling’s face was gentle and she smiled slightly. She took a sip of the water glass at her desk before she got up and asked seriously, "Tell Aunt Liang about your adjustment of the proportion of yttrium, barium and copper oxides."
Li Yuanling knows that the Dongda Thermal Conductivity Center has trained three people in yttrium barium copper oxide compounds. The three people have the ability, curiosity and equipment. It is also possible to change the original formula of Dongda and find a new critical temperature conductive compound in the yttrium barium copper oxide compound family.
"Mom is a new chemical guide, and the history has never been seen before. If we break through the liquid hydrogen barrier in the field of human guide in the first two years, the route will be rewritten." While staring at the corridor, Liang Yuan expressed the new practical significance of the three people in the simplest language.
This time, Li Yuanling thoroughly understood the true meaning of that sentence when Bai Ning Wan Jia entered the door.
"Mao" —— "Pa"—
The glass in Li Yuanling’s hand fell off the office floor and bounced, then it hit the steel supporting foot of the seat and smashed into pieces.
For three minutes, except for a few people breathing, the room was as silent as death.
Vaguely separated from other places, it is said that from a distance, the room is stagnant and the air is loose.
"How is that possible?" Li Yuanling’s weak voice is like a candle in the wind.
"This is impossible!" Li Yuan Lingyin slowly established herself.
The fact that the new conductor has been realized by the two girls is much faster than that of Li Yuanling. It is because of Li Yuanling’s understanding that she doesn’t believe that such a thing can happen miraculously.
Li Yuanling looked at Liang Yuan’s three people’s stable look. The belief has just been established, and it has been shaken violently. It seems that he is not in tune at ordinary times, but this kind of big event Liang Yuan has always been more reliable.
Maybe … The three of them misread the record by hand?
At the thought of this possibility, Li Yuanling’s belief that it is impossible to have children was slowly strengthened.
Fuck up before the desk words directly connected to the administrative office.
"Xiao Juan, you are on duty." Compared with usual, Li Yuan Lingyin is a little sharp.
"Where is your home in Zhou Heng?"
"The horse asked him to come to the door of the diesel locomotive as soon as possible."
Li Yuanling stared at Liang Yuan and said slowly, "Xiaoyuan’s mother didn’t see what she was saying with her own eyes, and she wouldn’t believe it. Go to the guidance center with her mother and repeat all the steps you three just experimented with."
"Yes, yes, it’s best for Aunt Liang to follow the guidance. Some of us don’t believe what we just saw."
Two girls than agreed to say
Looking at the three women hurried out of the door, Liang Yuan smiled smugly and picked up the ground kit and put it behind him and headed for the door.
"Zhi–"
There are still two corners from the gate of the gas locomotive, and a sharp brake comes from outside.
Liang Yuan with NingWanFei behind out of the car front door Zhou Heng has put the sea lion bread sliding door sitting driving position waiting for a few people.
"Xiao Zhou goes to the guidance center as soon as possible." Finally, Li Yuanling slammed the door.
"Li is always the guide center of Dongda?" Zhou Hengyin with a hint of confusion.
Fu Juan sounded as if something had happened. Li Yuanling was in a hurry to get to the car, but the place was too close.
Looking at Yuan-ling Li nodded to make sure that Zhou Heng threw aside his incomprehension and stepped on the gas pedal to the end. Suddenly there was a start-up tire scream outside the car. First, he had a meal and then suddenly jumped up. In an instant, the sea lion went away for 3 yards.
After talking all the way for a minute, Zhou Heng pulled the car to the entrance of Dongda Guide Center. Before the car stopped, Li Yuanling pulled the door.
Guide center No.3 laboratory gate
The cheap green iron lock nose imprisons the light yellow wooden doors in the No.3 pilot laboratory. Liang Yuan noticed that he had just left with two girls, so that the third-ring lock was still tilted with the trademark nameplate. It seems that no one has been here during this period.
Dig out the lab key from the back kit. Liang Yuan hit the lab across the hall and went in.
"Xiaoyuan, where do you say the new materials are?" Li Yuanling’s wandering eyes and finding out everything.
"Mom, I told you this thing is cross-generational. Now where can we put this kind of public place?" Liang Yuan smiled and pulled out the bottle containing magnesium diboride from the back kit.
"What is this that is very similar to the Yttrium-barium-copper-oxygen family compound?"
Li Yuanling took the bottle and turned it several times, but now the label of the type of injection on the bottle has been torn off and left a few white traces.
Yttrium-barium-cupric oxide and magnesium diboride are similar in color. Both of them are cyan, but Yttrium-barium-cupric oxide tends to be cyan, and magnesium diboride is closer to black and gray. From the outside, they really look like an element family.
"Think of it as a Yttrium-barium-copper-oxygen compound family," said Liang Yuanbian, turning on the circulating refrigerator source.
Liang Yuan took out the two magnesium diboride wires prepared by Ning Wanjia and handed them to Li Yuanling, saying, "Mom, this thing is prepared by Jiajia."
