"Boss, I'm here!"

As soon as he entered the door, Luo Dong said loudly. You could tell from his tone that he was happy, as if he had accomplished something remarkable.

Tang Fei noticed that Luo Dong was followed by two young people, who should be the doctoral students he brought, and each of these two doctoral students had a large suitcase.

If you can drag your suitcase to the door of your office, it will definitely not be luggage. It wasn't luggage, it would be something.

Soon, Tang Fei thought of a possibility.

"Come in and sit. Tang Fei warmly beckoned Luo Dong in. As for Luo Dong, he waved his hand to his two doctoral students and said, "You guys drag the box in, put it on this side, and then you can go out." ”

The two of them took the suitcase in as they said, put it on the side, and then gently retreated, and gently closed the door of the office. Both of them knew that their mentor and Tang always had something more secret to discuss.

There were only himself and Luo Dong in the office, and Tang Fei's eyes involuntarily fell on the two large suitcases.

Luo Dong noticed Tang Fei's gaze, and he said with joy on his face: "Boss, guess what's inside?"

Tang Fei had actually guessed it, deliberately thought about it, and said contemplatively: "Well, let me guess, if I'm not mistaken, it should be a complete set of technical information for the traction motor system of the DJ4 electric locomotive, right." ”

"Boss, you are really like a god!" Luo Dong looked admiring.

Three months ago, Tang Fei gave Luo Dong the technical information of the simplified version of the DJ4 traction motor, and instructed him to carry out design and development on this basis.

"Boss, it is the complete set of design data of the traction motor system of the DJ4 electric locomotive, which is packed in two large boxes. ”

Tang Fei had seen the simplified version of the technical information, and he personally printed it out and handed it to Luo Dong, and the information at that time was only a thick stack, far from the extent of two large boxes.

Tang Fei was very interested and wanted to see what the detailed version of the entire set of design materials looked like, so he immediately said: "Quick, open the box quickly, let me take a look." ”

Luo Dong personally opened the two boxes in front of Tang Fei, and inside were neatly placed technical materials, in addition, there were dozens of 3.5-inch floppy disks.

The capacity of the floppy disk is very small, and it takes so many sheets to copy the entire set of technical data in the electronic version into the floppy disk.

Tang Fei picked up a stack of technical materials and looked at it on his large desk. Tang Fei himself is a technical god with strong technical skills, and there is no problem at all in reading these materials.

After reading a part of it, I am very satisfied, these design materials are very detailed, a variety of design drawings are not missing, size, technical requirements, technical parameters, etc., marked clearly.

With such a complete set of technical data, as long as it is a slightly powerful motor manufacturing enterprise, it is estimated that it can successfully produce the traction motor system of the DJ4 electric locomotive.

Because the whole set of information is too detailed and complete.

Tang Fei said with satisfaction: "Luo Dong, you are worthy of being a well-known motor expert in China, and you did not disappoint me at all." ”

Luo Dong said modestly: "Boss, the main thing is that the technical information you gave me has played a huge role, we are just refining and improving this technology, and if we replace other people, they can probably complete this kind of work." ”

I don't know if someone else can complete it, but I am sure that it will never be completed in three months, and it will take a long time to finally complete it, and it is estimated that it will not be as detailed and perfect as this set of technical data.

After flipping through some paper technical information, such as design drawings and design outlines, Tang Fei's eyes fell on these dozens of floppy disks.

Luo Dongdao explained: "This is an electronic version of the design data, and I have copied the entire set of technical data into these floppy disks, each of which has a number and a table of contents on it. ”

Tang Fei said with emotion: "There are really a lot of floppy disks used." ”

Luo Dong said a little helplessly: "No way, the capacity of the floppy disk is too small, if anyone can invent a portable storage medium that is easy to carry and has a huge capacity, it will be great." ”

Tang Fei smiled.

He is really doing research in this area, and after a few months, he has basically done the same, and he is almost ready to form his own research results.

In the first half of this year, the design of the USB flash drive will be completed, and then it will apply for a national patent, and then apply for an international patent.

Seeing Tang Fei smiling so mysteriously, Luo Dong asked curiously, "Boss, what's wrong?"

Luo Dong is one of the people in his summoning department, he is absolutely loyal and reliable, and it doesn't hurt to reveal some appropriately, so Tang Fei said: "Luo Dong, I am working on a mobile storage tool, it is very small in size, very convenient to carry, and the storage capacity is very large, and the read and write speed is very fast. ”

Ah, there's such a thing.

Luo Dong looked at Tang Fei with a look of surprise, "Boss, you are so powerful, you can invent this kind of thing, as soon as it comes out, I am sure that it will definitely set off a huge change in mobile storage." ”

"Hmm. Tang Fei nodded, completely sure of this.

Luo Dong came, and also brought a complete set of technical information on the traction motor system of the DJ4 electric locomotive, and Tang Fei immediately held a meeting.

All the technical personnel participated, in addition to Wang Hailong, Yang Chenglin, etc., the conference room was full, Tang Fei announced that the traction motor system of the DJ4 electric locomotive was successfully developed.

Suddenly, warm applause rang out!

Especially Zhao Ke and others, they fully knew the technical gold content of this, and they applauded excitedly.

Then, Luo Dong introduced the traction motor system of the DJ4 electric locomotive, even if it was just a simple introduction, but it did not prevent everyone from knowing that this traction motor system was more than one grade higher than the current Shaoshan traction motor system.

After Luo Dong's introduction, Tang Fei personally explained the task, and solemnly instructed Zhao Ke and other technical backbones to carry out process design on the technology of this set of design materials.

Of course, there is also a simplified version of the process data, on which Zhao Ke can refine and improve.

Even if it is a simple version, it will save a lot of trouble, because the process data of this simplified version will be roughly determined, and the main production and manufacturing process will also be determined.

The current engineering and technology department can be described as strong, is the most powerful department of the entire Jiuzhou Industrial Company, other departments may only have three or five people, but the engineering technology department has more than a dozen people, and many are elite technical personnel of the summoning department, many are excellent motor experts.

Tang Fei said: "Zhao Ke, give you two months, on the basis of this set of design data, combined with this set of simplified version of the process data, you will make a detailed process flow, detailed process production materials, how about it?"

Zhao Ke was full of confidence and confidence, stood up, and said loudly in front of so many people: "Boss, it doesn't take two months, one and a half months is enough." ”

"Okay, then a month and a half!"

The new professional plant for the production and manufacturing of the DJ4 electric locomotive traction motor system has been completed, and Tang Fei also hopes to start the trial production of this AC traction motor system as soon as possible.

In a month and a half, the whole set of detailed process data came out, and the trial production preparation work can be started, Tang Fei's plan is to use more than half a year, in the second half of this year, to try to produce the first set of AC traction motor system.

This meeting was relatively long, and Tang Fei personally arranged a lot of work, after all, the trial production of the traction motor system of the DJ4 electric locomotive is not a trivial matter.

………

Red Star Factory.

Since the second half of last year, they have been manufacturing some parts of the DJ4 electric locomotive, and many parts have been manufactured, and finally passed the inspection and review of Siemens.

Large parts such as bogie, locomotive chassis, car body and other large parts have finally been manufactured and qualified. In the body workshop, a dedicated locomotive bench is ready.

As the workers know, this is specially prepared for the DJ4 electric locomotive. The first major process in the production and assembly of electric locomotives is to open the underframe.

The so-called "open underframe" is to assemble the bogie system, install the underframe of the car body, and then install the car body after the underframe is completed.

In this way, the "shell" of the electric locomotive is installed, and the shell will be sent to the spraying workshop for painting, and after spraying, it will be sent to the final assembly workshop to start the formal final assembly.

The final assembly is the focus, and many things will be installed on the motor locomotive, such as traction motor system, transformer system, control system, etc., many things.

The trial production of DJ4 electric locomotive is a big deal, no, Chang Jinlin and Xie Zhenhua came to the body workshop together to check the assembly progress.

Because it is a trial production of a new model, everything is a crossing of the river by feeling the stones, and it must be done step by step, even if there are people from Siemens in charge of technical guidance, there will definitely be a series of various problems in the whole process.

There is no hurry, you have to take your time.

However, seeing that the assembly of the car body finally began, the two of them were satisfied for a while, talking and laughing, and they were in a good mood.

Chang Jinlin is even more optimistic: "It is estimated that in the second half of this year, our first DJ4 motor locomotive will enter the assembly workshop, and then start a series of assembly work." ”

Xie Zhenhua replied: "Well, it should be about that time, around September or October, and strive to complete the main assembly work by the end of this year." ”

Chang Jinlin seemed to remember something, and asked: "At that time, didn't you say that the traction motor system was going to be installed on our locomotive, I don't know how Tang Fei's development progress of their traction motor system is, we will put all the treasure on Tang Fei, this little Tang, don't drag us back!"

Xie Zhenhua knows Tang Fei very well, and knows that Tang Fei's promise will generally be done, but for such a big thing as a traction motor, Xie Zhenhua does not dare to pack a ticket.

He thought for a while and said: "Well, we haven't asked Xiao Tang about the progress of the development of traction motors for a long time. ”

Today's fourth watch, the second watch is sent!
