While they were talking, the chief engineer of the shipping company came over with great dissatisfaction and said, "Old Qi, this Boss Peng is too conceited, right?" Does he really want to repair a better subbox than the original subbox? The support frame of the entire power compartment is deformed, and it would be good if he could repair the subbox and run it, do you still want to make up for the deformation of these support frames and the deformation of the subbox shell? ”

Qi Lao asked quietly, "Isn't it impossible?" ”

Chief Engineer Zeng said affirmatively: "Of course it can't be! I think it is impossible for the Germans to come by themselves, how high the technology must be, almost to redesign and manufacture the subbox, no, it is more difficult than redesigning and manufacturing a new subbox, because he does this, he must spend a lot of energy to move the already deformed box, must spend a lot of energy to correct the deformed power compartment base support frame, it is simply redundant, the gain outweighs the loss. ”

Speaking of this, he said a little ashamedly: "Even if it is me, even if it is our chief engineering office, it is difficult to complete such a large workload. Because the deformation of the support frame and the deformation of the subbox are too complex and irregular. ”

As long as people who understand mechanical technology know that it is easy to make a regular shape thing, even if the requirements are very high, such as making cylinders and cuboids, you can use a precision lathe to turn and use a precision planer to plan. But it is very difficult to make an irregular thing, for example, it is very, very difficult to make a lump of earth that is exactly the same as a lump of dirt from metal, because it cannot be turned out with a lathe, nor can it be planed out with a planer, but can only be milled little by little by a milling machine. It is difficult to grind little by little by the grinder, not to mention the processing, but also to measure whether it meets the requirements.

Now Peng Huading is repairing the precise central axis on the basis of the irregular deformation of the box and the support frame, which is definitely an unimaginable thing, so as the expert Chief Engineer Zeng is so angry, it is a bit strange that Peng Huading is asking for trouble. According to his idea, he Peng Huading can make the box run normally, a little error is a little error, it is better than the ship can't run, and the old ship can't become a new ship no matter how much it is repaired.

Qi Lao and Mr. He looked at each other and smiled.

Chief Engineer Zeng looked at them puzzled and asked, "What's wrong?" Am I not right? If he is allowed to do so. We don't know when the ship will be repaired. ”

Qi Lao patted him on the shoulder and said, "Xiao Zeng, we've all looked away. Now they just want to show us their hands and shock us. His purpose is to repair a set of subboxes that are not worse than the original price. In the future, it is justified to ask us for more ship repair business.

If you do it. Just take the damaged ones out. Replaced with imitation parts, its performance is definitely not as good as the original, plus the deformation of the support frame and the deformation of the box. No matter how good he is, the problem has not been fundamentally solved, and the consequence is that the vibration is large, the noise is high, and the efficiency of power transmission is not high.

However, he is based on the deformed support frame and the bottom of the box on the basis of imitation, not only imitation, but redesign, especially the shaft in the box is to adapt to those changes, but not so simple imitation, more complex than redesign. ”

Chief Engineer Zeng is also a technical expert, he looked at Peng Huading, who was busy, and only turned his head to Qi Lao and said after a long time: "Does he have this ability?" ......, is he necessary? It's a bit of a trouble for him to do this, it's better to redesign and build a new one, besides, our company has promised that as long as he repairs this set of boxes, the maintenance task of the ship's power compartment will be handed over to them in the future, so why do it? ”

Qi Lao shook his head and said: "I don't know, maybe people are just trying to convince us, just hoping to open up the situation here and make a model for us." ......, maybe there are many masters with expertise among the subordinates he called. ”

Chief Engineer Zeng sighed and said: "He wants to advertise our shipping company, hehe, can you say that he stepped on our face for others to see?" Forget it, who told us that we don't have the ability to do this, just advertise with us. ......, Qi Lao, the old man surnamed Li among them seems to be a bit of a doorway, and he has a very accurate grasp of the overall size, so he should be an expert in assembly.

However, I paid attention to the side, it seems that this kid surnamed Peng is still more powerful than him, at the beginning he was still commanding the person surnamed Li, and it was not until the surname Li fully understood his thoughts that he let the surnamed Li take charge alone. Hey, tell me, when did these cattle people emerge in Yuejiang City? ”

In fact, when Chief Engineer Zeng was still suspecting Peng Huading of asking for trouble, Zhang Guoshu, the interim general manager of the hiking equipment company, was also complaining and questioning why Peng Huading did this? His idea is the same as that of Chief Engineer Zeng, just repair this subbox and make it operational, what does it have to do with a little more vibration and noise, after all, this is repaired on a bad system, how can it be better than the original? It's so hard and troublesome, it's better to design and build a new set by yourself.

You must know that when he first started, he even doubted whether the people on his side could be repaired, until he saw Peng Huading commanding Ruoding and full of confidence, and then he had a little confidence. If it weren't for Peng Huading, he Zhang Guoshu wouldn't have dared to take on this kind of work at all, this German-made box is too tall.

Of course, Peng Huading wanted to design and build a new set of subboxes himself, but he couldn't do it, at least not for the time being. First of all, there is too much time, and when the shipping company finally gives itself 20 days at most a month, they can't always wait for you, especially if they don't know if you can succeed. It is impossible for them to watch a 10,000-ton giant ship rest and wait here, and they still hope to ask German experts to repair it, even if it will be slaughtered by the Germans.

The second is that the design and manufacture of the subbox box is very complex, and its complexity and trouble are far greater than the design and manufacture of gears and crankshafts. The gears and transmission shafts can be bought from the market, and as long as the drawings come out, they can be processed immediately. However, the box, especially the large box, can be much more troublesome, the design drawings have to be much more than the gears, transmission shaft drawings, it at least has a large set of casting drawings, to manufacture the casting mold, to turn the sand, and then it is far more complex than the gear, transmission shaft processing is much more complicated machining.

Such a large box casting is not something that can be completed by ordinary machinery factories, and Peng Huading cannot be completed in the workshop of the hiking equipment company no matter how skilled he is, let alone Yunfeng Technology Company, which must go to a large machinery factory or foundry, and must use their large steelmaking furnace and large casting equipment.

I was lucky to find such a machinery factory and foundry, and the other party promised to cast it for you, but it didn't take half a year or even a year, and you didn't think that they would cast a new set of boxes for you, let alone that they could cast boxes with the same precision as German companies.

The third reason is that this subbox already has a very high range of automation, there are many electronic sensors in it, there are a lot of sensitive discussions, and there is a set of electronic systems to monitor the operation status of the subbox. If Peng Huading wants to make a new one, he has to spend time designing such a system, and he will get chips and sensors that cannot be purchased in China from abroad.

The last reason is that even if Peng Huading has manufactured a set of marine substations with excellent performance, it is difficult for you to get on the ship in a short period of time, because you have not yet obtained the license of the classification society, if you want to let it get on the ship, especially the tens of thousands of tons of giant ships, first go to the classification society to queue up, and wait for a few years later, it will be their turn to send people to test and test, and only after they think that they are qualified will give you a license, so that you can use it on the ship.

Waiting for permission from the classification society, who can afford to spend such a long time?

In fact, the reason why Chief Engineer Zeng said that Peng Huading was asking for trouble and doing more is not really hoping that Peng Huading would redesign and produce a set, but that he thought that Peng Huading did not have the ability to repair the damaged subbox better than the original, he thought that Peng Huading was too good and ambitious, and should calm down and replace the damaged parts in this set of subboxes in a down-to-earth manner, so that the subbox could run on the line, and the repaired subbox was almost worse than the original performance, and anyone can understand and agree.

……

When Chief Engineer Zeng was still slandering, Peng Huading was making good progress.

With the instrumentation of the shipping company, with the help of the experts of the two companies, the measurement progress of the main number jù is very fast, many times only need Peng Huading to say, it will not take long for these numbers to be measured by the experts, and the number jù is accurate to the best accuracy of the instrumentation.

Seeing that the measurement work was going smoothly, Peng Huading no longer pointed fingers on the side, but thought about how to disassemble the parts that the Germans had set up obstacles, and how to take out the bearings, shafts, and gears that were equipped with memory alloys.

Memory alloys are very mysterious, in fact, many of the current memory alloys are related to temperature, and when the set temperature is reached, it will return to its original state or change its shape. Peng Huading wanted to take it down, the most important and troublesome thing was to find their corresponding jump temperature, and finding it was like finding the key and password to open the safe, and the problem was solved.

Peng Huading squatted on the top of the transformer, took a flashlight and looked at the place where other parts covered most of the field of vision for a long time, and also thought about it for a long time, and had a rough plan in his heart. (To be continued......)
