Northern Province, and state power plants.

Next to a huge power turbine, a dry official, technician and worker looked at each other, and there was any expression on his face.Among them, especially the Longshan motor factory director section Zhengwei's expression is the most desolate, very tall and strong a man, the eyes have been covered with a layer of tears.

“What’s this special?”It’s okay to have a problem even one week at night!”

Duan Zhengwei was hoarsely complaining to Feng Xiaochen, who was around.

Hearing the news of the failure of the 600,000 units of the Hezhou Power Plant, Duan Zhengwei and Feng Xiaochen, who are waiting in Beijing to fight with the Dingnan Planning Commission, are blind.Talking about the national beam, they can think of things, Feng Xiaochen they can also think of.They hold the flag of self-reliance, put pressure on the talking country, and have a moral advantage.Zhu Julan, the little news they heard, some of them were arranged by Feng Xiaochen to spread, and more people in various circles to supplement with their own imagination.Feng Xiaochen is naturally happy to see this rumor spread, because it will bring endless trouble to the South Province.

Just as the dawn was in the past, when the flag was about to surrender in Dingnan Province, its own backyard suddenly caught fire.The accident of the power plant in the state, solidly in Feng Xiaochen, Duan Zhengwei's face with a heavy note, so that the big flag raised can not stand up.Feng Xiaochen himself is a person who is good at conspiracies and yang plotting, and he can't imagine how to use the southern side to create momentum at this time.At the very least, everyone mentioned the National Planning Commission, the Planning Commission can no longer help Longshan Electric Factory to say anything, Feng Xiaochen in the previous various operations can be described as to pay the tide.

After Wang Zhenbin heard the news, he called Feng Xiaochen for the first time and asked about his attitude.Wang Zhenbin had previously spoken to Wang Jinsheng, and it was Feng Xiaochen who was entrusted.However, Wang Zhenbin said those words is not wrong, because Dingnan Province is indeed wrong in the first place, Wang Zhenbin's words are fully in line with national policies, even if Feng Xiaochen does not entrust, he also said this, but the attitude may be more gentle.

Now the wind is turning sharply, there is a problem with domestic equipment, Wang Zhenbin's previous tough attitude has become a handle, and it may be pointed out by the southern side.Wang Zhenbin has some regrets in his heart, feeling that he should not go to this trip for the sake of his classmates, but things have happened, what is the use of regret?

"Big brother, this matter is not clear yet, I am ready to go to the scene with the people of Longshan Electric Factory immediately to understand the specific situation."The policy of self-reliance is always right and will not be denied because of one or two accidents.On the south side, you still drag as much as you can, and don't let them get through.I think they are at best embarrassed by this incident, but they absolutely dare not say that the foreign moon is more round than China, unless they don't want to do it, don't you say?"Feng Xiaochen comforted Wang Zhenbin on the phone.

“That’s it too.”Wang Zhenbin felt a little solid.And the state power plant domestic equipment problems, is not a particularly big thing, where there is absolutely no problem of equipment?The trouble with this matter is that it is too coincidental, just happened to happen to the peak of the sanding power plant bidding incident, so that Dingnan side found a statement.But to think deeply, can you deny self-reliance because of a failure of domestic equipment?I’m afraid no one would dare to say that, would you?Wang Zhenbin represents political correctness, and there is no need to worry about it on any occasion.

Feng Xiaochen calmed Wang Zhenbin well, and let Duan Zhengwei contact the people on the side of the Ministry of Finance, so that they should not easily succumb to the pressure of Dingnan, and everything should be clarified.Later, he and Duan Zhengwei took a flight to Beining Province and came to Hezhou Power Plant.

Hezhou power plant is no stranger to Feng Xiaochen.He and Du Xiaodi first met, because the Longshan Electric Factory shipped to Hezhou power plant 600,000 kilowatts of motor stator in the road accident, which was rushed to the camp.Later, Feng Xiaochen has been to the state power plant several times, the most recent is to participate in the state power plant domestic 600,000 kilowatts of power generation celebration.

The 600,000-kilowatt unit of the Hezhou power plant is not the one that the camp has been repaired.At that time, it was said that it was a domestic unit, in fact, 70% of the components were from the United States, belonging to a unit made in the United States and assembled in China.Of course, the experience of that assembly is also valuable for Chinese enterprises, and the engineers and workers of Longshan Electric Factory have learned a lot from it.

This time, the unit is the second 600,000 kW unit manufactured by Longshan Electric Factory.The unit uses the design drawings of Xiyi Company, most of the parts are manufactured domestically, and only a few parts with particularly high technical requirements still use imported parts, and the localization rate has reached the expected requirements.After the equipment was manufactured, it was shipped to the state power plant for installation, and carried out low-load trial operation, which was well-effective, and was commended by the Ministry of Machinery and the Ministry of Water and Power.

This time, Zhengwei ran to Beijing to bid the Shating power plant project, and his own introduction materials also had the content of the 600,000-kilowatt unit in the state, but also a very heavy part.Who knows, it was the crew that dropped the chain.

"We started 100% load testing two weeks ago, and it was found that the thrust bearings were too warm, reaching 120 degrees Celsius, and the axial thrust reached 52 tons, which far exceeded the design allowable value, so the shutdown inspection was carried out."Zhai Shaohua, chief engineer of the power plant in the state, introduced the situation to the crowd.

It turned out that Wang Jinsheng got more or less of the news, the problem is not what motor spindle, but the thrust bearing of the steam turbine, the nature of the problem is not as serious as he said, at least not to the extent of causing fire.Of course, the temperature of 120 degrees Celsius is enough to make the lubricating oil smoke, and everyone spreads like this.

"This turbine was designed by the United States Siyi company, and as soon as we found the problem, we sent a fax to Xiyi Company and asked them to analyze the cause of the accident."They believe that there is absolutely no problem in the design, the problem should be in the manufacturing and installation, and some possible situations, including the leakage of the pipe piston, the unopened balance hole of the adjustment level, the leakage of the nozzle room, etc..”Longshan Electric Factory chief engineer fully built to plug the head and continue to introduce.

“Do these things exist?”Yang Le, director of the Ministry of Electricity, asked.

We urgently reviewed the records of equipment manufacturing and installation, repeatedly checked it many times, and asked the operators that these situations were unlikely.In recent years, we have implemented total quality management, each process has strict quality inspection requirements, the possibility of such a big mistake is very small.

“If it’s not these questions, what else could be?”Yang Le asked.

The whole building turned its head to see Duan Zhengwei, hesitant to know how to say it.Duan Zhengwei also hesitated, and then said in a low voice: "Chief Yang, we have a guess that the problem may not be with us, but there is a problem with the design of Xiyi's company."

Yang Le was a little surprised, immediately put his face on the sun, said: "The director of the section, as the director of a factory, you say this is responsible."Xiyi company is a world-renowned large enterprises, people have built more power generation equipment than all our power generation equipment in China, such a 600,000 kilowatt unit, there is a problem.I can understand your feelings, there is such a thing, no one wants to see.But this practice of abrogating responsibility is very inappropriate.”

As soon as this was said, Duan Zhengwei's face could not be hung, and he had the heart to argue a few words, but he did not know how to say it.He also knows a little bit of the motor thing, but after all, he is not a professional and technical staff, and some principles are not clear.He turned back and said to Quan Jiancai: "Old man, you talk about the situation you are considering, let Director Yang refer to it."Also, Feng assistant is not here, he is also engaged in technical origin, perhaps can also give some advice."

The whole building nodded, pointed to the thrust bearing on the steam turbine, and said to Yang Le and Feng Xiaochen:

"Chief Yang, Feng Assistant, you see, this problem first shows that the thrust bearing overheating, we analyze that the reason should be that the thrust of the bearing exceeds the design requirements."With this consideration, we measured the axial thrust of the bearing and found that the axial thrust was nearly 2 times higher than the design value, so as to determine the cause of the failure was too high axial thrust.

These days, we focus on the technical strength of the whole factory, according to the design, manufacturing, installation, operation of the reasons for the possible problems, made a very comprehensive causal analysis map, and then calculate one by one, excluding all kinds of unreal possibilities, excluding some unimportant factors, and finally found that there is only one reason for excessive thrust, that is, there is a problem with Siyi's design method.

When we introduced the technology of Siyi, the Americans taught us a full set of calculation methods, and their steam turbines were calculated in this way.We calculated the turbine in the same way, and the result was that the axial thrust would not exceed 28 tons, while the actual measurement was 52 tons, which indicates that their calculation method must be defective.”

“What, the calculation method is flawed?”Yang Le is a bit embarrassed, he is not a technical cadre, can not understand the calculation method what is exquisite.The whole construction is the master of Long Electric, technically very cattle, he can say that there is a problem with the calculation method, Yang Le is really good to refute him.

"Since the total workers think that it is a problem in the calculation method, let's start with the calculation method."Feng Xiaochen calmly said, "digestion and absorption of the introduction of technology, where there is so easy, there is a little problem is not great."I think it would be useful to us that something like this has happened, whether the ultimate responsibility is outside or on ours, and at least we can have more of the ability to analyse the problem.”
