With the sound of alarm bells ringing one after another, Li Guishan turned on the test switch.
A huge roar sounded immediately, and Feng Chen knew it was the sound of the giant compressors installed outside the device. Li Guishan once introduced that each compressor can provide a pressure of more than 10,000 psi. These compressors
The compressors are combined in parallel to achieve the environmental pressure required for the test.
Li Guishan did not put all compressors at full load this time. After all, the test was only 20,000 psi.
Feng Chen stared at the computer screen in front of him. The pressure value on it was slowly increasing, and he kept conveying the value changes to Li Guishan.
"The pressure has reached 10,000!"
"13000!"
"15000!"
"Reduce the power of Unit 2 to 40%!" Li Guishan said calmly.
"16000!" Feng Chenyi reported the pressure value again.
Slowly, the pressure in the manifold reached 18,000 psi. This value has reached the advanced level in China. However, for the Blue Whale, which is about to go to sea, this is only just over half.
"The pipes are normal and the valves are normal. You can go to the next step!" Feng Chen glanced at the data on the screen. They were all within the green normal range. Only one or two were in the orange alert, and they were all within the acceptable range.
.
"How about video surveillance?" Li Guishan asked.
"Everything is normal, no abnormalities found!"
After more than ten days of monitoring, the entire device seemed to be still, as if there had been no change.
This is a very good phenomenon. Li Guishan's expression remains unchanged. He knows that everything is normal, and if something happens, it will be abnormal.
"Prepare to enter the water!" Li Guishan preached again. Although this sentence was said to himself, it could be regarded as an encouragement to himself.
The high-pressure water immediately rushed into the manifold, churning like a sharp arrow, baptizing all the gaps in the manifold, seemingly trying to find any chance to escape.
"The pressure is stable!" Feng Chenyi said.
Li Guishan was obviously relieved, "Get ready to maintain the pressure!"
As soon as he finished speaking, he heard Feng Chen say, "Reduce the pressure, 300 per second, trigger the alarm!"
"Increase pressure maintenance, check monitoring equipment, and prepare personnel to evacuate!" Although the pressure drop is not serious, dangerous factors must be considered, and personnel safety is the first priority.
Feng Chenyi immediately found the problem in more than a dozen screens, "There is a slight pressure release in valve No. 3!"
I saw a piece of white mist-like water vapor appearing on the screen. This was the vaporization phenomenon of high-pressure water under sudden pressure changes. Fortunately, the pressure relief was not too serious.
"Close valve No. 3!" Li Guishan took immediate measures.
This pipeline system has undergone many high-pressure tests, and its safety is trustworthy. After the valve is closed, the pressure of the entire pipeline becomes stable.
Li Guishan quietly communicated with Feng Chenyi about the pressure changes in the entire pipeline to verify the effectiveness of the test plan.
Ten minutes later, Li Guishan announced that he had begun to slowly relieve pressure.
Compared with pressurizing the pipeline, the pressure relief work is slow and very dangerous. Various media in the pipeline may spurt out during the pressure relief, which will cause great risks and must be dealt with carefully.
Feng Chenyi also paid attention to the situation of several pressure relief vents, which will be places where risks will explode in the future.
After more than three hours of intense work, the 20,000 psi test was finally over. Although there were a few minor accidents during the process, the effectiveness of the suppression plan and risk assessment plan formulated by Li Guishan was finally verified. For the next step,
High stress testing lays the foundation.
The test also exposed some problems, especially when encountering emergencies, manual intervention is still required, which will bring safety risks to rescue workers.
Overall, the entire experiment was relatively successful.
Feng Chenyi made a detailed report on the entire test process and submitted it to the Blue Whale Construction Headquarters.
Although it is only a short stress test, and even the test pressure is only two-thirds of the final test, this result also makes everyone very happy. Only sufficient preventive and safeguard measures can ensure the successful completion of the entire task. Now we are waiting.
The final stress test plan.
The partner schools are also busy nervously. In order to leave a good impression on Fuhai Group and make a good start for future cooperation between the two parties, the schools attach great importance to this modeling, which has also led to some
The consequences that make people laugh or cry.
That is to strive for excellence in this modeling and not let go of any shortcomings.
The high-quality requirements have caused the entire modeling speed to slow down, and also made Li Guishan and others anxious.
Zhou Yan finally couldn't wait any longer. If he did this, he might really have to wait for ae group to come over to "help". He immediately ran to Zhang Yujie, told the situation again, and asked him to help tell the partner colleges as soon as possible.
To come up with a suitable plan, they still need further screening.
Zhang Yujie knew that his position was insufficient, so he immediately explained the situation to the school in the name of Lu Zhengtao.
When the school saw that Fuhai Group was waiting impatiently, they hurried over to explain and then promised to send the final plan as soon as possible.
Perhaps the instructions worked, or the school sped up the process. A week later, the school’s modeling plan came out. It was carefully selected by the school and was enough to fulfill Feng Chenyi’s requirements.
The moment he got the plan, Li Guishan was stunned. The results that he had to go through many times to get were all displayed on the computer in just a few hours without any danger.
"This thing is really good!" Li Guishan looked at the final demonstration result on the computer and said sincerely.
"Yes, this is the power of technology!" Feng Chenyi stood aside and said with a smile, "But in your words, this thing is still just talk on paper. We still need to verify it with actual operations. After all, not all real things can be compared to computers.
It’s like a simulation, anything can happen!”
"That's right!" Li Guishan turned to Zhou Yan and asked, "How about we do a practical operation based on this?"
"You said boarding the Blue Whale directly?" Zhou Yan was also shocked by Li Guishan's suggestion.
"That's right!" Li Guishan pointed to the test field behind the studio and said, "I can't simulate 30,000 psi here, but the Blue Whale can. Then after on-site investigation, we will formulate the final implementation plan based on our previous plan.
, this is the fastest and most effective!”
"I'll ask the chief engineer for permission on this matter!" Since the Blue Whale was involved, Zhou Yan didn't have the courage to agree directly.
