With the completion of the 5,000-hour test run and the beginning of the final full-life test run, Wang Bin also came to the aviation laboratory basically every day, and carried out a full-life test run with Professor Poke and others. Of course, this can also be called This is a destructive test run.
As the test runs, 5500 hours, 6000 hours, 6500 hours, the performance of the ten engines are exceptionally good, and nothing happens.
When the test run time reached 7000 hours, at this time, the fuel consumption of one engine among the ten engines began to increase. When it reached 7200 hours, the fuel consumption of the ten engines on the test bench basically began to become somewhat somewhat It's high, but the sound of the engine is pretty good.
But when the test time reached 7,600 hours, the fuel consumption of the engine on the No. 3 test bench became abnormally high. At this time, whether it was Professor Piao or Wang Bin himself, it was clear that the life of this engine had come to an end. , At the same time, the situation of other engines running away is not better than that.
Sure enough, when the engine test time reached 7,700 hours, all engines experienced a sharp increase in fuel consumption. Even when the No. 3 engine was running, there was a slight vibration and a slight noise.
Finally, when the test run reached 7,800 hours, Professor Piao finally gave the order to stop the test run, because at this time the malfunctioning engines on the ten test benches had already experienced a sharp increase in fuel consumption, engine vibration and abnormal noise.
So at this level, the test run is no longer in progress, because whether it is Professor Poke or Wang Bin knows that the situation inside the engine must have been very bad at this time. If the test run is going on, it is likely to happen. Unnecessary accidents.
When all the engines on the test bench were stopped, the entire test workshop fell silent, and everyone in the test workshop fell silent, because whether it was Professor Poke or Wang Bin, or the test workshop The rest of the staff, even those who are not sure about the operating time limit of aero engines, know the meaning behind the 7,800 hours of full-life test run, especially for China.
You should know that if such data is placed a few years ago, even if it is the best engine of China, all the life spans from the new engine to the three overhauls and then to the end of life will not be able to reach this data, so this test data It's definitely very, very powerful.
About ten minutes after coming here, the young people in the test workshop suddenly remembered the violent cheers. At the same time, their hearts, including Wang Bin and Professor Piao, felt extremely proud because of their engine. The life of water has created a miracle.
Of course, like these young people, Wang Bin was extremely excited. He praised Professor Poke and everyone present on the spot. At the same time, he issued a large number of red envelopes in the aviation laboratory group. , To celebrate with a table, and finally announced that the salary of everyone in the entire aviation laboratory will double from this month.
You know, this is an aviation experiment! These people themselves, as technicians in aerospace, their own salary levels are several times higher than those of other people in Tiangong Technology, and now they are doubled on the original basis. How can this make them not Happy!
So when Wang Bin announced the news, all of a sudden, the people in the laboratory became even more excited.
Until everyone's mood calmed down, Wang Bin and the technicians in the laboratory disassembled all the ten engines on the test bench and sent them to the assembly workshop to prepare to disassemble the ten engines one by one. solution.
Of course, because the test project just completed this time is a destructive full-life test run, all this dismantling is just to know the internal conditions of these engines, so there is no need for cleaning and reassembly.
However, the necessary inspection is still necessary. After all, the internal parts of the engine are so precise, even if it has reached this level, many things are not visible to the naked eye.
However, at this time, Professor Wang Bin, Professor Piao and others judged that among the ten engines, the most severely damaged should be on the engine. After all, the bearings on these engines should bear the greatest pressure compared to other components.
Even if this bearing is made of the best bearing steel of Tiangong Technology, its standard is only relative to the current level of human civilization, so if you want to make the bearing life longer, then you must use it. Bearings made of more advanced bearing steel will work.
All these ten engines were transported to the workshop, and the technicians immediately followed the engine technology to start dismantling these engines, and they were quickly dismantled.
With the dismantling of these ten engines, Wang Bin, Professor Piao and others all stepped forward and looked at it carefully. After all, even though these engines have passed the final full-life test at this time, so the The parts are no longer the same as they were when they were brand new, and they have become black and white, and even many parts are stained with oil.
However ~www.mtlnovel.com~ The judgments of Wang Bin, Professor Piao and others are not surprising. After a series of tests, the other parts of these ten engines are in very good condition. There will never be any problems after using it for 10,000 to 20,000 hours.
However, when he and the others saw this engine bearing, they found that these bearings may look good at this time, but if they look closely, they will find that the bearing steel **** are no longer the same as when they were brand new. All are metallic luster, without the slightest blemish.
At this time, if you look at the bearing carefully with a magnifying glass, you will find that there are dense small black spots on the steel ball of the bearing at this time, and a lot of wear marks and even metal peeling appear on the bearing sleeve. phenomenon.
Later, Wang Bin and Professor Piao checked all the bearings on the ten engines one by one.
He found that almost every bearing on these ten engines had such a situation more or less, especially the main bearing, this phenomenon was even more serious.
When he saw this, Wang Bin stopped. At the same time, he thought to himself that he had to work harder on the bearing steel and the bearing itself to improve the quality of the bearing again.
Of course, if it is for other companies, it is impossible to improve the quality of bearings in a short period of time. What's more, the bearings of Wang Bin and their Tiangong Technology are already the world's top bearings, and they want to upgrade even more. It's difficult.
But that is only for other companies. For Wang Bin, this is not a problem that cannot be overcome. For him, as long as there are enough energy coins, it is not a problem to improve the quality of bearing steel and bearings. ,
