It takes about a week for a piece to be processed from powder metallurgy through rough machining and nano-finishing.
It took more than a month for snail steel to process this set of gas turbine parts, and this set of parts, which represents the most precise ball, was transported from Cangzhou to the ice city.
Not long after the Spring Festival, several large trucks from Bingcheng Beifeng Factory delivered these expensive parts here.
After getting these pieces, Chen Xuedong and Dong Xincheng immediately organized engineers to assemble a new generation of gas turbine engines.
They haven’t found anything yet, but when they installed the parts, they found that the perverts didn’t feel the tolerance.
Chapter one hundred and thirteen L
Several installation engineers can’t believe that there is such a huge gap between the blades produced by Beifeng Factory itself and those produced by snail industry.
An engineer brought the blades produced by Beifeng Factory himself, and after two comparisons, the gap was even more obvious 2.
"Is this gap too big?"
It seems that the leaves on both sides are silver gray, but if you pick up the snail leaves, each leaf is almost the same if it is the same type.
And picking up their own north wind blades, even the same specifications, are slightly different from each other.
"Dong Gong, your snail finishing is too awesome, which is almost as accurate as Simon’s blade."
Dong Xincheng laughed "Simon precision? I tell you that the accuracy limit of snail industrial processing is 1 nanometer. "
"What … 1 nanometer?"
"my god!"
"Is this really machining accuracy?"
Dong Xincheng casually explained that "it is relatively high to adopt a special process, and it takes a long time to process"
Aside, Chen Xuedong’s face was a little hot and quickly changed the subject. "All right, hurry up and don’t procrastinate."
"Ha ha"
Although the machining accuracy has come, it will test the assembly technology of engineers more.
All engineers put out 100% spirit to debug the size of the piece a little bit and make it as perfect as possible.
After more than a week of sleepless nights, the gas turbine was finally assembled.
Because they developed the gas turbine on the ground, the test platform of the generator set is relatively simple, and if it is a ship, it is relatively troublesome to test the gas turbine.
Connected to the simple test platform of transformer equipment, the gas turbine was fixed, and everyone was heart-warming.
"Chen Gong!" Table of Re-inspection of Dong Xincheng
"Good" Chen Xuedong picked up the walkie-talkie. "Everybody take your positions."
"Roger that"
As time goes by, when methane gas is injected into the gas turbine, it runs wildly and the power rises rapidly.
The advantage of gas turbine is that it is very fast to start, and it takes about 15 minutes from low power to power.
Chen Xuedong turned his head and his tone was a little nervous. "How much does a single stage burn?"
"Wait a minute" The data analysis engineer hurried to calculate the data with his fingers and keyboard flying, and immediately shouted "365%"
“365%？” Chen Xuedong notes this data and asked about the temperature and pressure.
This temperature and pressure have been running for half an hour, and it hurts a little. Chen Xuedong ordered "Enter the cyclic combustion test"
"white"
After a half-hour cycle combustion test, the data obtained is that the thermal efficiency is 46%. This data is barely enough, but the ratio is insufficient and more than enough.
Chen Xuedong is quite satisfied with this data, which is much higher than before, but considering the high temperature resistance of new materials, he also wants to try "Dong Gong, let’s conduct temperature and pressure tests!"
"Ke" Dong Xincheng also wants to see the effect of this new material.
As the intake pressure and gas temperature gradually rise, all engineers become more nervous and keep a close eye on the test data.
The gas turbine on the test platform is more crazy. With the increase of gas temperature and intake pressure, the power output of the gas turbine also increases.
The engineer in charge of calculating the test data has never stopped his fingers.
Chen Xuedong didn’t order to stop raising the temperature and pressure until the air pressure and temperature of each sensor reached the critical point.
It continued to run for half an hour.
"The single-stage combustion of Chen Gong and Dong Gong reached 413%, and the cycle combustion reached 556%." The tone of the calculation data engineer was full of excitement.
"Good" Chen Xuedong also flushed with excitement.
Everyone in the whole control room cheered, and many people cried with joy. The gas turbine researchers in China were so wronged and depressed that Lucia had a better foundation than China.
Perhaps snail engineers such as Dong Xincheng don’t feel that happy, because the scientific and technological explosion of Suiren Company brings that kind of spirit to Suiren researchers and engineers, which is different from the national spirit. They are full of confidence and fighting capacity.
Ten minutes later, when the excitement passed.
Dong Xincheng came out to throw cold water. "This breakthrough is really gratifying, but everyone still needs to continue to work hard. This time, the efficiency increase of gas turbines is a blessing of material performance. Can you imagine if Simon gets this material?"
Gollum! Suddenly everyone calmed down, and many engineers felt a little ashamed. After all, they relied on materials to design, which was barely enough.
Dong Xincheng went on to say, "Come on, everyone! Efforts will be made to design that may surpass ventilation and Simon. "
Chen Xuedong is also clearly aware of this problem. "Dong Gong is right. There is still a gap between us and the international mainstream level. This is an indisputable fact. We must not miss this foundation now."
On the other hand, the general manager of Beifeng Company hurried out to speak, "Everyone didn’t go home in the New Year, and the company won’t forget everyone’s hard-earned bonuses and doubled performance, and so on."
Pa pa pa … A group of engineers immediately applauded and introduced the management mode of Robinia pseudoacacia Ant Company. Beifeng Company implemented a model similar to that of China and Suiren Company. Employees have virtual shares and dividends.
It is against the physical rules to ask the horse to run without letting the horse eat grass, just like an engine that wants the engine to run fast and does not allow the fuel consumption to increase, the engine limit is locked.
After the morale was boosted, the tester continued
However, Beifeng Company did not stop moving, customized five sets of accessories to snail industry and sent good news to all shareholders.
It is normal for Beifeng Company to ask shareholders such as Datang Fa, Huaneng and Hua for money.
As if to say, you see, I’m almost chasing Simon and ventilated now, so hurry up and invest more money.
As soon as the five delegations saw this report, they couldn’t sit still. In the past, the team of engineers was mainly sent to check the real situation.
It’s no wonder that many research projects in the five major countries are really cheating sometimes.
At that time, Harbin Institute of Technology made a big joke about changing water into oil, and the infamous "Hanxin" directly hit the chip of China.
Soon, the five teams of engineers sent a delegation to the ice city, and many engineers looked suspicious before the actual measurement was carried out.
After all, the cycle combustion efficiency of the gas turbine in Qianbeifeng Plant was only about 4%, and it rose to 556% in just over a month, which was close to 5% in Ximen.
When the gas turbine roared, after careful and face-to-face inspection, the engineers of the five major groups confirmed that the gas turbine efficiency was consistent with the reported data
