When Peng Huading came down from above, Qi Lao walked over and asked, "Xiao Peng, is there a way?" ”

Peng Huading nodded and said, "It should be about the same." But in order to carry out my plan, I had to unload all the surrounding parts and expose the surrounding space. I reckon it will take a day, and we'll have to wait until tonight or tomorrow morning. ”

As he spoke, he patted the place where the barrier had been set up and said, "I took a look, and there are about four places where there are barriers. ”

Because of his old age and poor eyesight, Qi Lao couldn't climb up to inspect it, and even if he went up, he couldn't see it, but he still nodded and asked, "Is it convenient to tell me what measures you will take?" ”

Peng Huading replied: "No problem. In fact, it is very simple, that is, to use high-frequency alternating current heating, so that the alternating current can flow through these metals to generate heat, and when the temperature here reaches the transition temperature, the memory alloy inside will return to its original state, and they will not be able to jam the parts, and we can take out the shaft and gear. ”

Qi Lao smiled and said, "Hehe, yes, I can't think of such a simple way." ......, though, how do you know the temperature is just right? We can't see the inside, and when we heat it with an electric current, who knows if their shape has changed? On what basis do we cut off the current? ”

Peng Huading smiled and said, "This is our secret." I can't sue you for how to do it. It's not that I don't believe you, but after all, you are Party A, we are Party B, and we want to make money from you. I promise you won't spread it, but I can't promise that others won't pass it on, and that's what we rely on to make money. ”

Soon, Peng Huading said with a smile: "It's not that I'm selling off, I'm actually using the internal shape of the metal to change, and its internal stress and electrical properties will have some changes, and I just use special methods to capture this change." Thus making judgments. ”

Originally, Qi Lao wanted to ask if it was to use its internal resistance to change, but he couldn't help but ask, although he was an expert in the field of machinery, he also knew that if it was only the change in the shape of some alloys inside, the change in its resistance would be very small, and it would not be enough for the instrument to measure it.

"What exactly does he use to make judgments?" Qi Lao thought silently.

If he knew that Peng Huading was because he had advanced knowledge, he knew the changing temperature used for several memory alloys. He just tried these temperature values one by one, and he always knew that one temperature was suitable, and he was afraid that he would cry and laugh: this kid is really a liar.

In fact, even if Peng Huading didn't already know the transition temperature of several alloys, he did have a way to test them, because he knew that once the memory alloy changed inside the metal. In addition to the change of resistance, the internal stress changes, and its natural frequency will also change, and he has the same way to test it, but in this case, he needs to assemble a test instrument by himself, and it will take a little longer.

If Qi Lao really thinks and studies according to the method he said. can really research huge results, he is not a mouthful, let alone a fool in the real sense.

Qi Lao glanced at Peng Huading thoughtfully.

……

The flame is high when everyone gathers firewood, and the strength of many people is great.

Under Peng Huading's unified command and dispatch, the disassembly of the subbox was very good, even faster than Peng Huading himself expected, and most of the parts in the subbox had been disassembled before it was late at night.

The whole subbox is the size of a house. The parts inside are far from the size of the parts that people usually see, the shaft here is hundreds of kilograms, and a main gear is also hundreds of kilograms, and several people can't lift it, so they can only use a crane.

Seeing the gears larger than the table top being broken, and the brick-like teeth falling into the lubricating oil, everyone present sighed that the huge power to drive the ship to ship is nothing under normal circumstances. When used as a destructive force, its power is even more infinite.

These disassembled parts are carefully measured, tested, drawn and entered into the computer by experts and technicians, and experts also carefully judge whether they are damaged or failed.

It was late at night. Many people went home, and there were basically only a few technicians and experts from the hiking equipment joint stock company who Peng Huading agreed to stay, including Zhang Guoshu and Li Jiasheng.

Qi Lao and other technical experts are too old to wait here for a long time, and Peng Huading obviously doesn't want them to stay here to peep at the secrets, they are all arrogant people, and when they see others wary of them, they leave the scene as soon as the time to get off work comes. However, Mr. He and other leaders had too many things at hand, and they only asked about the results of the maintenance of the ship, and did not worry about the process, and left after watching the excitement at the scene for a while.

Of course, there were still a few people from shipping companies left at the scene, such as Liu Yangjun and others, who were in order to cooperate with Peng Huading's actions, including laying cables and transmitting power supplies.

Zhang Guoshu watched Liu Yangjun put the thick cables next to the subbox, and couldn't help but ask in a low voice with a little worry: "Boss Peng, will this method work?" ”

Peng Huading said lightly: "Almost, right? Hopefully, it will be a one-time success, or I'll have to find another way to delay here for an extra day or two. ”

I heard that it was only a delay of one or two days, and Zhang Guoshu's worries were much less.

Peng Huading and Liu Yangjun instructed the electrician to connect the cable to the box. Seeing the several cable connection positions selected by Peng Huading, Liu Yangjun, Zhang Guoshu and others felt more down-to-earth, feeling that these positions seemed to be deliberately left by the Germans, although they also played the role of fixing the bolt connection holes.

After all the preparations were completed, Peng Huading carefully checked again to confirm that the cable was installed in place, the relevant disassembly preparations had been completed, and the relevant personnel had stayed in a safe position, and he calmly pressed the power conduction button.

As his button presses, high-frequency alternating current begins to feed into the box, shaft, and gear, and begins to heat up the metal parts.

He took the infrared thermometer and began to carefully check the temperature in several places he had already set. Although they have installed temperature sensors in these places, Peng Huading still likes the intuitive feeling.

When the local temperature of the subbox reached the first alloy jump temperature he remembered, Peng Huading reduced the current output, and after fifteen minutes of waiting for the temperature temperature, he cut off the power supply, and then let people start a special hydraulic disassembly machine to drag the spindle outward with a cylinder driven by high-pressure hydraulic oil, but the action failed, and the spindle did not move.

After the equipment was restored and the personnel returned to a safe position, Peng Huading turned on the power again and heated it until the temperature of the subbox reached the second alloy jump temperature that he remembered, and he kept this temperature for fifteen minutes.

But the second attempt still failed, the spindle was still stuck in the bearing sleeve and remained motionless, and the special hydraulic dismantling machine was running in vain.

But Peng Huading was not discouraged, he believed that no matter how high the current memory alloy technology is, there are definitely not a few types of memory alloys, and with his own memory, he is confident that he can solve this problem.

He then tried again, raising the temperature of the subbox to the third jump he remembered.

After fifteen minutes of this temperature had stabilized, he cut off the power and instructed the technicians who had been ready to make a third attempt to start the special hydraulic dismantling machine.

Just when everyone thought that this time it would also fail, as the cylinder of the special hydraulic disassembly machine was injected with high-pressure hydraulic oil, only a slight click was heard, and the spindle was slowly dragged out and slowly withdrawn from the spindle bearing hole.

"It worked! We did it! Zhang Guoshu was overjoyed and shouted like a child.

The others also cheered excitedly, everyone, you look at me, I look at you. Even a few technicians from the shipping company who cooperated with Peng Huading also laughed happily, and Liu Yangjun rushed to Peng Huading and said, "Great! Boss Peng, you are too powerful. ”

Peng Huading also breathed a sigh of relief: finally he didn't have to take the most troublesome road, and he didn't have to assemble the tester by himself.

He smiled and said to Liu Yangjun: "Fortunately, I didn't misremember the number jù, and the technical publications of the gringos did not fool me, and it was really this temperature." ”

The reason why he said this was purely to cover up his own strength, so that others would think that he had read foreign technical publications and knew how to disassemble them.

……

The main problem has been solved, and the next work is to imitate, that is, to build those damaged parts one by one, and replace those damaged parts to use them.

Zhang Guoshu can do these jobs, at least they can complete most of the work in the early stage, Peng Huading has no need to stay here all the time, he can't do it as a boss. The more he does, the less the people below him do, which not only easily tires himself, but also hinders the motivation of others and hinders their technical improvement.

He just needs to make the final check.

After he explained the matter to Zhang Guoshu and Liu Yangjun, he got off the steamer, said goodbye to them and went back to his place.

He fell asleep until almost noon the next day, and when he had slept enough, he felt that he was not tired.

Just after washing up, he was about to go downstairs to the company for lunch when he heard a knock on the door.

When he opened it, he was surprised to see his parents standing outside with a smile.

"Mom, Dad? How did you get here? Didn't you say that you didn't buy yesterday's train ticket and had to leave the day after tomorrow? Peng Huading looked at his parents in surprise.

The mother smiled proudly: "Hehe, stinky boy, are you scared?" Can't we do anything else, we just won't let you pick it up. ”

Peng Huading hurriedly invited them in and helped his father move the suitcase into the living room.
