What's the most important thing in an electric locomotive?

It is not the car body, nor the underframe and wheelset, but several major systems of the electric locomotive, such as traction motor system, electrical control system, voltage conversion system and so on.

The excellent traction motor system and the excellent and advanced electrical control system indicate that this is an electric locomotive with excellent comprehensive performance.

Hongxing Factory is a large factory, with a history of decades, starting from steam locomotives, to diesel locomotives, and then to Shaoshan series of electric locomotives, they have a relatively strong locomotive manufacturing technology and technical reserves, manufacturing electric locomotive body, chassis and wheelset or something, they have no problem at all.

Their weak link is in the electrical system part, such as the traction system of the AC motor, such as the electrical control system of the locomotive, such as the voltage conversion system of the locomotive, and so on.

This time with Siemens, these core systems, Siemens technology is confidential, only provide relevant parts, guide the Red Star factory for assembly.

Tang Fei's chess game is very big, since the technology of Siemens is confidential, it is up to us, Jiuzhou Industrial Co., Ltd. to develop a world-class traction motor system on the electric locomotive, excellent electrical control system and so on.

Not long ago, Tang Fei and Chang Jinlin reached an agreement that Jiuzhou Industrial Co., Ltd. would first try to make the traction motor of the Shaoshan series of electric locomotives, and then accumulate a certain amount of experience, and then at a certain time, they would consider letting Tang Fei make the traction motor system of the DJ4 electric locomotive.

has begun to make traction motors, but this electrical control system has not yet been seen, Tang Fei has been thinking about when he can start to make electrical control systems.

Tang Fei's idea is that the core system of the electric locomotive, including the traction motor system, the electrical control system, the converter system, etc., the core and key systems of the electric locomotive, we must master them all, and cannot be controlled by others.

Now's your chance.

The Red Star Factory could not meet the requirements of Siemens and make high-quality electrical control cabinets, Tang Fei's idea was that since the Red Star Factory was not good, it would be up to us.

It is not all of the electrical control cabinet, just a cabinet, without a series of complex electrical components inside, Tang Fei is fully sure that Jiuzhou Industrial Co., Ltd. will be able to make it, and the quality is definitely far better than that of the Red Star Factory.

Tang Fei himself has an aura of quality +1, which will invisibly improve product quality, and in addition, Tang Fei himself is also very good at welding.

At the beginning, the quality problem of the welding of the aluminum alloy inner plate was solved by Tang Fei. The cabinet of the electrical control cabinet is welded by stainless steel plates, and the quality problem of the Red Star Factory is in the welding, Tang Fei is sure that under his own guidance, the workers of Jiuzhou Industrial Co., Ltd. will be able to weld qualified.

Besides, Tang Fei still has a large number of engineering and technical personnel under him, and there are several elite technical talents in the summoning department, in addition to a total of six new college students.

Tang Fei is full of confidence and confidence!

"Cheng Lin, since the Red Star Factory is not good, then it is up to us, I will personally go to the Red Star Factory and ask for this business. ”

Yang Chenglin agreed: "Yes, since they can't do it, then let's go up, our No. 1 plant is a professional welding workshop, and it has an idle area of about 2,000 square meters, which is just used for welding electrical cabinets." ”

Just do it.

Tang Fei immediately left his office and drove to the Red Star Factory. This time, he went directly to Chen Guihong, instead of Xie Zhenhua or Chang Jinlin.

It's just the cabinet of the electrical control cabinet, to put it bluntly, it's a shell, without a large number of complex electrical components inside, such a thing can only be regarded as a general thing.

If it is an important and key spare part, Siemens will not do it for the Red Star Factory, such as the electrical control cabinet, the Red Star Factory only makes the cabinet, and the important key electrical parts inside are provided by Siemens to guide the Red Star Factory to assemble.

Because it is not an important thing, Chen Guihong has the power to call the shots, and there is no need to rise to the height of Xie Zhenhua or even Chang Jinlin.

"Brother Chen!"

When Tang Fei pushed the door in, Chen Guihong was in the office, and seemed to be writing something on the desk, when he heard the movement, he looked up and saw that it was Tang Fei, and immediately put down the pen in his hand happily.

He said happily: "Brother, why do you have time to come to me, I heard that you are busy these days, and you haven't appeared here for several days." ”

As a brother, Chen Guihong is still more concerned about Tang Fei, knowing that Tang Fei is doing some big things, such as preparing to make traction motors, such as the construction of new plants, and even the huge factory area in the entire planning has begun to invest funds, began to carry out land leveling, the laying of trunk roads in the factory area, and the construction of the grand gate of the factory area, etc.

Tang Fei said: "I've been a little busy recently, and I don't even have time to sit here with Brother Chen." ”

Chen Guihong got up, made tea for Tang Fei, and asked with concern: "What, why do you have time to come over today, do you have something to do with me?"

Tang Fei didn't beat around the bush, and said directly: "Well, I heard that something happened in the Red Star Factory, the welding quality of the electrical control cabinet of the DJ4 electric locomotive is not good, and it can't meet the requirements of Siemens, isn't it." ”

"Yes, there is such a thing. Chen Guihong first admitted that there was such a thing, and then inevitably complained: "These foreigners are too old-fashioned, I heard that the welding quality of the electrical control cabinet is actually good, but there are some small defects, which do not affect the use, these foreigners just bite it." ”

Hearing this, Tang Fei smiled bitterly and shook his head gently.

At this time, the domestic manufacturing industry generally does not attach great importance to quality, and pursues things such as output and profitability.

In the next few years, after entering the 21st century, with the deepening of international cooperation, domestic manufacturing enterprises and foreign manufacturing companies began to contact and cooperate, because the quality awareness was not high enough, and many profound lessons were learned.

At that time, the entire manufacturing industry in China began to gradually pay attention to quality. The same is true of the current Red Star Factory, where the general quality awareness is not high.

As a reborn person, Tang Fei believes that quality is the lifeline of an enterprise, and has been insisting on doing a good job in quality and making products into high-quality products.

The previous aluminum alloy interior panel is like this, keep improving. The same is true for the terminals, which pursue excellent quality. Later, when I made motors, it was the same, and I always put quality first.

Under the influence and influence of Tang Fei, the employees of the entire Jiuzhou Industrial Co., Ltd. have a strong sense of quality, and have almost reached the level after more than ten years.

Seeing Chen Guihong say this, Tang Fei suggested: "Brother Chen, no matter how big or small the defect is, it is at least a defect, which affects the quality of the product, and such a defect must be eliminated. ”

Chen Guihong thought about it, sighed and said, "There is nothing wrong with saying so, but ......"

Originally, I wanted to argue a few words, but I felt that what Tang Fei said was not wrong at all, so Chen Guihong sighed and said a little depressed: "It's just that in this case, when will our electrical cabinet be qualified, I heard that three cabinets have been scrapped, and the fourth estimate that is being welded now is also hanging." ”

Tang Fei smiled.

This is an opportunity for yourself, the Red Star Factory can't make high-quality electrical cabinets, so it's up to you. Tang Fei suggested: "Brother Chen, since it has been scrapped several times in a row, let's give it a try, let's give it a try, how about it?"

You guys!

Chen Guihong looked at Tang Fei in astonishment, he couldn't get an idea at all, he couldn't do it himself, Tang Fei could do it.

Tang Fei said confidently: "Brother Chen, do you remember our aluminum alloy interior plate, how is the welding quality?"

When it came to the interior board made by Jiuzhou Industry Co., Ltd., Chen Guihong wanted to give a thumbs up, and immediately said: "Your interior board is impeccable, and the welding quality is first-class." ”

"That's not enough, we are strong in the welding of aluminum alloy, and the welding of stainless steel is not bad, just make one for us." ”

Chen Guihong thought in his heart, his factory made several units in a row can not meet the requirements of Siemens, let Tang Fei give it a try, so Chen Guihong said: "Brother, yes, then you can try to make one, and we will sign a trial production contract now." ”

This is exactly what Tang Fei wants.

This belongs to the processing of incoming materials, the Red Star Factory has qualified raw material suppliers, and the supplier will cut the stainless steel sheets into good materials, completely according to the size of the drawings, and the Red Star Factory can weld these stainless steel sheets one by one, and finally become a cabinet of electrical control cabinets.

This time for Tang Fei, the sheet supplier will send the stainless steel plates directly to Jiuzhou Industrial Co., Ltd., and Tang Fei and they only need to weld them.

This is more convenient, Tang Fei promised that the cycle is one week, and within seven days, the qualified electrical control cabinet will be sent to the Red Star Factory.

Days passed.

The welding workshop of the Red Star Factory is still busy, the arc is splashing, and the workers are hurrying to work, but there are several workers with bitter faces and crying thoughts.

This is the fourth electrical control cabinet they welded, the first three are all scrapped, this was originally done, but the people from Siemens shook their heads after seeing it, pointed out a lot of defects, helpless, can only rework.

It is hoped that after rework, this cabinet will be qualified and meet the quality requirements of Siemens.

Several workers were depressed and busy, and it took most of the day to finally complete the work, and they checked it themselves and thought it was okay.

The inspectors of the Red Star Factory also conducted an inspection and thought it was okay, so they called the people from Siemens to inspect it.

Siemens has several quality engineers in the Hongxing plant, one of whom came to the welding workshop to carefully inspect the reworked electrical control cabinet.

Many people noticed that this foreigner's face gradually became serious, and after looking at it, the foreigner obviously shook his head gently.

Still no!

The translator next to him hurriedly said the meaning of the foreigner, and after listening, everyone knew that although there was a certain improvement, it was still unqualified, and this cabinet was still a defective product.

Knowing the result, the welding workers were deflated, and the technicians of the Red Star Factory who accompanied them were also depressed.

The atmosphere was dreary.

At this time, a large group of people came in from outside the gate of the welding workshop, and the leading person strode into a meteor, which was Chang Jinlin!

……………

Today's three watches, the third watch is complete!

Let's talk about the update casually, there are generally three updates a day, and the update time is generally at night. If there is something and there is less time to code words, there may only be two more. If the inspiration comes, full of code word motivation, it is okay to break out and update the four chapters.
