Chapter 92 Serious Quality Problems
"Hey……"

Yang Jun actually sighed again, his whole face suddenly became frowning, and he said in a low voice: "It's true that something happened, and it's not a small matter."

Hearing this, Tang Fei immediately paid attention to it, and immediately asked: "What happened, can you tell me?"

....
Red Star Factory, in the meeting room.

This small conference room was filled with smoke, and several cigarette butts had been wrung out in someone's ashtray. The atmosphere in the entire conference room was very oppressive and dignified.

The chief engineer and deputy general manager of Red Star Factory, Xie Zhenhua, presided over the meeting, and Chen Guihong was also present, attending the meeting.In addition, there are some comrades in charge of technology and quality, and some people in the assembly workshop, such as Lu Gang who sits not far from Chen Guihong.

Things start from last month.

Since last month, after-sales personnel in various road bureaus have sent back news one after another that there have been problems with the ventilation and cooling systems on the Shaoshan series electric locomotives.

At the beginning, the technical and quality personnel of Red Star Factory did not pay much attention to it, thinking it was an accidental factor. It was not until this month that the same problems gradually increased, and everyone paid attention to them.

The situation has also reflected on Xie Zhenhua, who is worthy of being a technical master of Red Star Factory. He found some clues from these problems.

After summarizing and analyzing these issues, Xie Zhenhua came to an astonishing conclusion, and immediately couldn't sit still, and immediately called relevant personnel to hold the first meeting a few days ago.

Others thought it might be just an occasional problem, but Xie Zhenhua saw the essence of the problem. At the meeting a few days ago, he expressed his inference in front of everyone, that it should be a major motor in the ventilation and cooling system. quality problems.

Electric locomotives need to consume a lot of electricity during operation, and with the consumption of these electricity, it will emit a lot of heat.

If the heat is not discharged in time, the temperature inside the entire electric locomotive will rise rapidly, which will inevitably affect the work of various electrical components on the electric locomotive and many systems.

To remove the heat, ventilation and cooling must be used. The Shaoshan series electric locomotives have a complete set of ventilation and cooling systems. The power source of this system is various types of motors. A large amount of heat keeps the temperature inside the locomotive within an allowable range.

If the ventilation and cooling system fails, the temperature inside the locomotive will be out of control, which will affect the operation of the locomotive and even be forced to stop.

Now, it was the ventilation and cooling system that had a problem, and Xie Zhenhua accurately deduced that the main cooling motor had a quality problem.

At the meeting a few days ago, Xie Zhenhua gave his own inference. According to this inference, the engineering and technical personnel of Red Star Factory, as well as a large number of technical personnel, used these few days to verify Xie Zhenhua's inference.

No, everyone held a meeting together again.

This is not a general quality problem. The situation is probably more serious. Before coming to the meeting, Chen Guihong was aware of this and inevitably revealed something to Yang Jun. That's why Yang Jun had that expression when he saw Tang Fei.

in the conference room.

A person in charge of quality was introducing the situation, and said loudly: "According to the request of Mr. Xie, we have summarized the problems related to the ventilation and cooling system in the past two months. There are a total of eight problems, except one caused by accidental factors. In addition, a total of seven cases were related to the main cooling motor."

It is really the main cooling motor!
Mr. Xie's deduction is completely correct!
Many people present looked at Xie Zhenhua in admiration, and then there were buzzing voices. Everyone is not a layman. If there are frequent problems with the main cooling motor, the problem may be more serious.

In the entire conference room, the silence suddenly ceased. Many people turned their heads and talked in low voices. Many people either frowned or showed a bit of worry on their faces.

Xie Zhenhua coughed, raised his hand and pressed it down, motioning for everyone to be quiet, and then said to the quality supervisor: "Continue to talk, and tell all the conclusions you have drawn."

"Well." The quality supervisor nodded and continued: "For these seven quality problems, combined with the feedback from the after-sales personnel of various road bureaus, we have conducted a serious analysis together with the technicians, and the main cooling motor has serious problems. quality issues."

Ah!
Serious quality problem!
Many people's faces changed slightly, serious quality problems, this is not a joke.

The quality supervisor described the data they analyzed in more detail, and also mentioned a professional term - machine break.

Yes, it's a broken machine!

This is a serious quality accident caused by the main cooling motor.

After the quality supervisor finished speaking, Xie Zhenhua waved his hand and said, "Vice President Chen, please introduce some of the loading conditions of the main cooling motors of our Shaoshan series electric locomotives."

Chen Guihong stood up, ready to speak.

Before the meeting, Chen Guihong collected a large amount of information, learned about the loading situation of the main cooling motors of the Shaoshan series electric locomotives in detail, and summarized the data.

Chen Guihong said: "Mr. Xie, leaders and colleagues, now let me introduce the loading situation of the main cooling motors of the Shaoshan series electric locomotives. Our Shaoshan series electric locomotives have been put into production so far, except for the previous batches that used imported main cooling motors. Except for the motor, the latter is completely localized, so far, a total of 540 two main cooling motors have been used.”

"These more than 3000 main cooling motors are mainly manufactured by our two domestic motor factories. Each motor has a service life of ten years. The main cooling fans of the seven electric locomotives that have problems are all domestic motors. The time limit ranges from more than three years to five or six years...."

Chen Guihong introduced the situation in more detail.

Thousands of main cooling motors are used in total, and the problems are all domestic motors.

Many people think in their hearts, God bless, don't continue to have such problems. If similar problems continue to occur, things will only get worse.

Xie Zhenhua also realized this, and his face was not at all relaxed. When Chen Guihong finished speaking, he raised his hand again, motioning for everyone to be quiet.

After the conference room quieted down, Xie Zhenhua began to deploy a series of tasks.For example, arrange personnel to remove the main cooling motors from the locomotives that have problems at the road bureau outside, and immediately return to the Red Star Factory for further technical analysis to find out the real reason.

Where exactly the problem lies, this must be clarified as soon as possible.To find out these, we must carefully analyze the faulty motor.

Then, Xie Zhenhua also ordered the after-sales personnel outside to pay close attention and focus on investigations to prevent similar quality problems from occurring again.

After Xie Zhenhua arranged a series of tasks, he waved his hand to signal everyone to end the meeting.

Everyone's faces were not relaxed, and they walked out of the meeting room with a little heavy steps.The same was true for Chen Guihong, who walked out of the meeting room with a solemn expression. Inadvertently, Chen Guihong saw that Xie Zhenhua did not leave immediately, but sat there.

Xie Zhenhua took out a cigarette, lit it, and smoked it slowly.To be honest, Xie Zhenhua's addiction to cigarettes is not heavy. He can't smoke a few cigarettes in a day. He only sits and smokes when he is thinking about something or encountering difficult things.

This time Xie Zhenhua sat alone in the conference room, smoking three cigarettes in a row.For some reason, Xie Zhenhua faintly had a bad premonition.

Mood said, I hope things will not be too bad, not what I thought.Xie Zhenhua squeezed out his cigarette butt, sighed softly, and was the last one to walk out of the conference room.

Tang Fei is in the procurement center.

Under Yang Jun's arrangement, Tang Fei drank tea in a reception room of the purchasing center, waiting for Chen Guihong's meeting to end.

The procurement center needs to contact many suppliers and purchase a large number of spare parts. There are several reception rooms with a good environment in the procurement center, and Tang Fei is one of them.

After slowly drinking more than half of a cup of hot tea, Tang Fei raised his hand to look at the time, thinking in his heart, it has been three or four ten minutes, Brother Chen should be finishing the meeting soon.

After waiting for a few more minutes, Tang Fei heard familiar footsteps and got up quickly. It was Chen Guihong who came in from the outside.
