Chapter 28 The first ignition operation of the unit
Liang Yuan looked at Liang Jiangping and wrote the 1.9mm crack in the report. In fact, if this matter was handled smoothly, it could be completely digested inside the branch. Anyway, it was an oil supply rack on the machine's nose that was broken. Comrade Lao Liang wrote down this problem and sent it to the road bureau, so that the branch office would argue with the Datong Locomotive Factory.
But now the nature of the cracks is changed as soon as they are written into the report, from affecting the national railway image to a major safety accident. It is estimated that all the rewards of the entire Andong Branch will be ruined in the second half of the year. In addition, if something happens to an international train, the branch may even be reported by the Ministry of Railways. My father's ability to attract hatred is really strong.
Liang Yuan couldn't help but ask: "Dad, if you hand over this report, will the branch be rewarded in the second half of the year be ruined?"
Liang Jiangping nodded and said, "This is simply a crime. What are the inspections and the maintenance staff in the branch office for food? Such a big crack is definitely not caused by the mileage from Anton to Tongyuan Castle. I have to focus on this matter tomorrow."
Liang Yuan looked at Liang Jiangping's indignant look and thought that it would be better not to mention the suggestions that he had digested within the branch. If he proposed them, he would probably be criticized by Comrade Lao Liang. Anyway, he didn't expect his father to be successful. He could sit firmly in the position of the section chief, even if God blessed him. He could do whatever he wanted.
However, after Comrade Lao Liang did this, Datong Locomotive Factory was liberated. Faced with the major driving accident where the entire train could be destroyed and killed, the problem of oil supply racks became unremarkable.
The next day, Liang Yuan stood on the rostrum temporarily built by the school gymnasium and read a speech about the Municipal Education Bureau's literary and martial ethics and bird-freshing fish soup to the leaders of the Municipal Education Commission, which brought the first time Benxi's city entered the final circle of the Youth Science Competition to a perfect end.
On June 20, Liang Yuan said goodbye to the two loli and returned to Shengjing after three or four days.
Liang Yuan sat on the sofa, looking at Li Yuanling frowning and thinking.
The unit data of the SBB-changed gas turbine has been released. As Liang Yuan expected, compared with the original SBB-changed s_ma1 gas turbine, the domestic unit data is a bit terrible.
Compared with the maximum power of the original SBG gas turbine of 13,800 kilowatts, the maximum power of the domestic SBG gas turbine is barely 9,500 kilowatts, and the fuel consumption rate is 62 higher than the original SBG 235 grams/kilowatt-hour, and finally stabilized at 297 grams/kilowatt-hour. This means that when using ship power and outputting the same power, the domestic SBG gas turbine consumes 14 tons of fuel per day than the original SBG.
Liang Yuan took the first ignition data of the unit from the coffee table and looked carefully.
After 72 hours of the first ignition operation, the third and fourth-stage blades of the compressor were slightly damaged, structural metal fatigue occurred at the rotor f50 of the gas turbine, occasional overheating of the power turbine, and the seventh exhaust system, and the twelve seal ring burned...
Liang Yuan skipped the various gas turbine failures written above and turned to the last page. After 72 hours of operation, the unit suffered 17 major structural components damage, 59 major components damaged, and 185 general components damaged, with minor...
Rich in the wrinkles, Liang Yuan closed the record report of Spee and put it back on the coffee table. According to the report, after ignition operation for 72 hours, the unit was overhauled.
Wu Zhonghua sighed long and pointed to the report on the coffee table and said, "The situation of the unit is very serious. It will take at least half a year to deal with these problems."
Li Yuanling picked up the report and pointed to the major structural damage and said: "The teacher's situation of metal fatigue in a short period of time is simply the consequence of Factory 423 blindly modifying the axial force. If I asked me to say that it would be better to completely push it down than to repair it on this broken basis, and re-imitate it completely according to the drawings of SB s_ma1."
Wu Zhonghua shook his head and said, "Now there is only one factory 423 investing in this project. Xiaoling, you want to modify the design of 423, which is equivalent to completely denying the work of 423, which is equivalent to telling 423 that the entire machine failed. The responsibility lies with you. 423 will never agree."
"But, the teacher's house is simply crooked now."
"I know this house is crooked, but unfortunately we have no other source of funds to rebuild a prototype. At present, we can only make major modifications based on the 423 design to rationalize it. For example, the axial force of the rotor mentioned by Xiaoling just now, we can solve the problem of metal fatigue by bolding the diameter. Of course, the specifications of the components that match the rotor also need to be changed, which requires a lot of experiments and calculations."
Liang Yuan then suddenly realized that all the confusions in his previous life suddenly became clear. No wonder Mr. Wu did not increase the life of the gas turbine until his death. According to what Mr. Wu said now, it was equivalent to redeveloping a gas turbine. The original SB s_ma1 drawing in his hand was equivalent to waste paper. However, in two years, Mr. Wu increased such a broken unit to a first-return life of 300 hours. It is also considered a genius. You must know that the British developed the SB sB s_ma1 gas turbine, which took 12 years to finally succeed with a sufficient budget.
Unfortunately, God didn't give Wu Zhonghua enough time, and he finally failed.
"Teacher, is there any news on the Navy?" Li Yuanling thought for a while and changed the subject.
"There is no final decision yet. Xiaoling will take the project team with peace of mind in the future. I will go to the funding issue."
"How come, the teacher is so old?" Li Yuanling said with some concern.
"When you go out to run for money, the teacher's old face is still effective. Xiaoling, you are too young and can't do such a job for the time being."
Listening to Li Yuanling and Wu Zhonghua planning for the future of the Sbet project team, Liang Yuan had countless thoughts in his mind. Now my uncle has 10 million in his hand. In July, at least so many parts of the gas turbine in the 909th Institute can continue to be used. According to Li Yuanling's idea, it cost about six or seven million to build a prototype. However, it would cost some money to kick the 423 factory 423 factory away from the troublemaker.
Liang Yuan, who has memories of his previous life, understood that Li Yuanling’s words were correct to start over. First, it was completely copied according to SBE’s drawings—"completely domesticized—" and slightly improved. In terms of gas turbine development, it is safest to follow this path that has been verified by the Japanese Navy Self-Defense Force in his previous life.
Funding is not a problem for the time being, but how should I mention it to my mother? Liang Yuan was confused.
