yes, what the hell is going on.

Professor Luo Dong said so, and Tang Fei said the same. Xie Zhenhua was puzzled, and several other people in the Red Star Factory were also confused, looking at Tang Fei in a daze, wanting to get an answer.

Tang Fei smiled and picked up a part on the ground, which is a spindle of the main cooling motor, which can be regarded as one of the most critical and important parts on the motor.

There is a certain amount of wear on this shaft, Tang Fei said: "Everyone knows that the problem is on this shaft, but I don't know why there is such serious wear, right?" ”

Xie Zhenhua said: "Yes, we really don't understand, why there is such serious wear, we measured the size of the shaft, and also read its design data, it fully meets the design requirements, there should be no problem." ”

Tang Fei said: "Chief Engineer Xie, what if the design data is wrong?"

Design data generally does not make mistakes, Xie Zhenhua instinctively did not consider this aspect, but has been looking for manufacturing reasons, process reasons, and even material reasons.

"Oh, there's a design error, no. Xie Zhenhua looked at Tang Fei in astonishment.

At this time, Luo Dong spoke, "Chief Engineer Xie, after our careful analysis, it is determined that there is a problem with the design, and the problem is in the decimal point." ”

It was really a design problem, and the motor was designed by its manufacturing company, and the Red Star Factory only put forward the relevant technical requirements.

No wonder Luo Dong just said that the Red Star Factory was cheated by this motor manufacturing company.

Luo Dong said: "After our analysis, we believe that this motor manufacturing company should also be negligent, there is a size of the decimal point wrong, resulting in an order of magnitude smaller size, if the new motor, this size is a little smaller It doesn't matter, but if the motor works for two or three years, it has oil and dust and other things in it, the problem will appear......"

Luo Dong analyzed it carefully, he deserved to be an expert in this area, he analyzed it like this, everyone understood it, and they all understood what the problem was.

Xie Zhenhua suddenly realized, patted his head lightly and said, "So that's the case, I kind of understand." At the same time, there was a sense of relief in my heart, and the problem was finally found.

Holding Luo Dong's hand tightly, Xie Zhenhua said gratefully: "Professor Luo Dong, thank you so much, otherwise, we would still be fighting back and forth in the same place, and we have not been able to find out the real reason." ”

After finishing speaking, he said to Tang Fei: "Xiao Tang, I also want to thank you, the problem has finally been found, I have been a lot more relaxed, I can go back and report to Mr. Chang later." ”

Tang Fei smiled and reminded: "Chief Engineer Xie, don't forget the agreement between us. ”

Xie Zhenhua agreed: "No, I've always remembered, come to my office tomorrow, let's talk in detail, how about it." ”

Tang Fei was overjoyed, "Then it's decided, I'll come over tomorrow morning." ”

Xie Zhenhua left happily with his people, and now he is finally relieved, because the real problem has been found.

As long as the real problem is found, it will be easy to deal with in everyone's opinion, and you can prescribe the right medicine to solve the problem completely.

Facts have proved that the Red Star Factory, including Xie Zhenhua, is a little too optimistic, and what happened later made them fully aware of this, of course, this is a later story.

Sent Xie Zhenhua, Tang Fei and Luo Dong away, walked around their own production workshop, and watched the production process of their own motors.

The motor production here, from the design of the motor, to the process layout of the plant, the selection and introduction of equipment, the process used, etc., are almost all carried out under the leadership of Luo Dong, which is specifically responsible for Zhao Ke and several doctoral students under Luo Dong.

It is worthy of Luo Dong.

The motor production process here should be relatively advanced in China, and the quality and performance of the motor produced must be good, Tang Fei is full of expectations.

Looking at the current situation, it will not be long before the first motor will be manufactured, which is the main cooling motor used in the Shaoshan series of electric locomotives.

This kind of motor is not cheap, each imported is as high as more than 30,000, and the domestic one is about 20,000, of which the profit is relatively large, which is also one of the reasons why Tang Fei insists on producing this kind of motor.

The first electric motor is about to be produced!

After looking at it for a while, Tang Fei thought happily in his heart, and at the same time said in his heart, this motor was designed by Luo Dong himself, using the most advanced production technology in China, and has its own quality +1 BUFF bonus, after the motor is produced, the quality and performance are really worth looking forward to.

Now that Rodong is here, he decides to stay here for a few days and watch the first motor being produced before returning to NJ University.

The next day, Tang Fei arrived at Xie Zhenhua's office as scheduled.

The two began to discuss the purchase of electric motors. As a condition, Hongxing Factory agreed to purchase Tang Fei's motor as the main motor of the ventilation and cooling system on the Shaoshan series of electric locomotives, that is, the main cooling motor.

promised to agree, Xie Zhenhua still put forward a series of requirements.

The main thing is quality and performance, where quality is the focus.

Xie Zhenhua said earnestly: "Xiao Tang, you must pay attention to the quality of the motor, there must be no problems in this aspect, so let's send a few sample motors first, we will do a comprehensive test, if passed, we will load the locomotive, do a series of performance tests, fully meet our requirements, and then we will sign an order." ”

Test and try first, pass and then purchase.

Tang Fei had also thought of this a long time ago, and it was completely within his expectations. As a newcomer in the motor industry, it is impossible for the Red Star Factory to purchase in large quantities at the beginning.

Tang Fei was very satisfied to be able to let his motor enter the Red Star Factory and promised to load the test, which means that he finally knocked on the door of the Red Star Factory.

As for the share of formal procurement in the future, it is too early to talk about these, and when the loading test is passed, the two agreed to discuss in detail the specific share and quantity of purchased motors.

For his own motor, Tang Fei is still very confident, as long as the Red Star Factory agrees to try it, even if the temporary share is undecided, future orders are absolutely indispensable.

Seeing that Tang Fei promised to try a few units first, Xie Zhenhua was also relieved for a while, he originally thought that Tang Fei would open his mouth wide, and he would ask for hundreds of orders as soon as he opened his mouth, but he didn't expect Tang Fei to be very reasonable.

Xie Zhenhua glanced at Tang Fei approvingly, and thought in his heart, this young man is not simple, and his future achievements are immeasurable!

After talking to Xie Zhenhua about everything, Tang Fei happily returned to his factory.

His first motor was about to be manufactured, Tang Fei didn't go anywhere, stayed in the production workshop, and personally watched the workers assemble the motor.

Today, it means a lot to Tang Fei because the first motor was built, which is a beautiful main cooling motor, which has been assembled.

When the workers finally installed the nameplate of the motor, Luo Dong said loudly: "Mr. Tang, our first motor has been assembled!"

In public, Luo Dong called Tang Fei "Mr. Tang", and in private, he called Tang Fei "boss", which was specially ordered by Tang Fei.

The first motor!

Tang Fei waved happily: "Okay, go to the comprehensive test bench, let's see how it performs!"

The comprehensive test bench was designed by Luo Dong himself, mainly used to test the performance and various parameters of the motor. Hearing Tang Fei's instructions, Zhao Ke commanded two workers to install the motor on the test bench and connect the wires.

It didn't take long for Zhao Ke to ask: "Boss, it's already good, you can experiment!"

Tang Fei walked over and pressed the red button himself, and suddenly, the motor rotated, and the test bench began to work and run, and various parameters were displayed on the instruments.

Zhao Ke personally acted as a technician to record the data. As the designer of this motor, Luo Dong personally looked at the data.

Minute by minute, minute by minute, the whole scene is only the sound of the motor working, very quiet.

Tang Fei was a little nervous at the beginning, but he knew technology, and after reading these data, a nervous heart gradually relaxed, and joy gradually appeared on his face.

"Mr. Tang, the data is perfect, the quality and performance of this motor are very good!" Luo Dong shouted loudly.

It is relatively rare for the first motor to do so well, no wonder Luo Dong is so happy. In fact, this may be related to the collective aura of "quality + 1".

After about half an hour, the test was over!

Luo Dong officially announced that the test was passed and the motor was fully qualified.

"Oh, that's great!"

"Haha, the first one is qualified!"

The workers who were assembling the motor next to them couldn't help but shout happily after listening to Luo Dong's words, and some even jumped up.

Tang Fei smiled happily, he hit it out, and the first motor was finally made, let me calculate, it seems that it has not been three months since I was ready to make a motor.

"Ding!"

In my head, a voice sounded, "Congratulations to the host for completing the mission!"

Hearing this voice, Tang Fei hurriedly checked the taskbar of the system, and sure enough, it was displayed as completed, and the reward of 800 gold coins had also been received, and the number of gold coins in the system was displayed as 850.

Lao Tzu has never been so wide, seeing these 850 gold coins, Tang Fei thought in his heart, there was a feeling like becoming a local tyrant.

With these 850 gold coins, you can do a lot of things, what should you do? Just as he was about to plan how to use some of the 850 gold coins, Wang Hailong walked into the factory.

He walked up to Tang Fei's side and said softly, "Boss, Cheng Lin is back, and Ian Donnelly is also here, waiting for you in the reception room." ”

Yang Chenglin is back!

It's a good thing, one after another. Yang Chenglin went out a few days ago, in order to continue to develop the market for the terminal, he went to Donghai City by the way, and visited Ian Donnelly according to Tang Fei's instructions, but he didn't expect to come back so soon.

"This Yang Chenglin, if he wants to come back today, he won't call me in advance. Tang Fei said with a smile as he walked out of the factory with Wang Hailong.
