This should be the eighth failure.

Just a few days ago, the after-sales personnel of the Hongxing Factory in the Outside Road Bureau reported back that another main cooling motor had failed, causing the locomotive's ventilation and cooling system to strike, almost stopping the electric locomotive in operation.

It was only after holding on to the next train station and changing the front of the train that the train continued to run. This incident made the leaders of the Road Bureau very angry.

A sternly worded official letter was also sent to the Red Star Factory, asking whether there would be similar failures in the Red Star Factory and whether the Red Star Factory could handle these quality failures.

Receiving such an official letter, the leaders of the Red Star Factory had a gloomy face, no, Chang Jinlin, the number one leader, personally attended this meeting, which is very rare in ordinary times.

For general technical and quality issues, it is very good for the following technical ministers to participate, and if it reaches the level of Xie Zhenhua, even Xie Zhenhua participates, it means that the problem is very serious.

Now, not only Xie Zhenhua personally presided over this meeting, but even Chang Jinlin personally participated, which shows the seriousness of the problem.

Xie Zhenhua said bitterly: "Comrades, this is the eighth quality accident related to the main cooling motor, and it all happened outside, the impact is very bad, in the face of the question of the road bureau and the locomotive depot, I am shameless, very ashamed!"

A lot of people have their heads down, and this is indeed a very shameless thing.

One after another, starting from September, in just two or three months, there were eight similar accidents, all of which were related to the main cooling motor.

Some engineering and technical personnel and some quality supervisors who participated in the meeting felt the heat on their faces one by one and lowered their heads.

In the whole conference room, the atmosphere was oppressive and heavy.

Xie Zhenhua said: "There have been eight incidents, and it has only been less than three months, and now I don't know whether there will be a ninth or even a tenth case." ”

Xie Zhenhua said for a long time, not only felt heartbroken, but also full of shame and self-blame in his words, and in the end, he took the initiative to say in front of everyone.

"Mr. Chang, I ask for punishment, my work has not been done well, I should be primarily responsible for this matter, and I accept how the factory punishes me. ”

Chang Jinlin sighed lightly and comforted: "Lao Xie, I, the number one, are also responsible, and if I want to be punished, I will start first." ”

"However, before punishing you and me, I think we must first find out the cause, what is the reason for the frequent failure of the main cooling motor. ”

yes, what is the reason?

It stands to reason that motors are mature products, generally very reliable, and difficult to fail. If one or two quality failures occasionally occur, it is acceptable and normal, but this is a succession of occurrences, and eight have occurred in just two or three months.

Chang Jinlin wants to know what is going on, and needs to analyze and find out the reason.

Xie Zhenhua nodded and said in agreement: "I think so too, first of all, we must find out the reason, at the last meeting, I have already made arrangements to ask our after-sales personnel outside to disassemble the faulty motor from the locomotive and send it back." ”

Raising his hand to look at the date on his watch, Xie Zhenhua said: "After so many days, some motors should be coming back." ”

Chang Jinlin waved his hand and said: "When these faulty motors come back, immediately organize technical forces and check for me to find out what the reason is." ”

And emphasized: "Not only to find out the cause, but also to come up with measures, to solve and eliminate this problem at one time, and never allow similar quality failures to occur again." ”

yes, the impact is so bad!

There are such problems one after another, no one can stand it, if it is held accountable from above, Chang Jinlin will also be hanging.

The best thing to do now is to quickly identify the cause, fix the problem, and prevent similar problems from happening again. Xie Zhenhua also agreed with this, he said: "Mr. Chang, rest assured, we will go all out, even if it is all night, we must find out the reason in the shortest possible time." ”

The meeting lasted for more than an hour, and after the meeting ended, all the participants in the meeting were in a bad mood, and almost all of them hung their heads and walked out of the conference room with their heads down.

After everyone left, Chang Jinlin and Xie Zhenhua sat in the conference room for a long time, and they were not in a hurry to leave, and they exchanged a lot of views with each other.

In the afternoon.

Xie Zhenhua's estimate was still very accurate, a long-distance truck drove into the gate of the Red Star Factory, and Xie Zhenhua was also reported as soon as possible.

As a result, the technical and quality system of the entire Red Star Factory almost took action, and the technical backbone, engineers, and even some quality supervisors rushed to the assembly workshop.

In the corner of the workshop, there are motors, all of which are faulty motors that are disassembled from the outside. Xie Zhenhua, the engineer, came in person and commanded in person.

Arrange inspectors to inspect, arrange recorders to record, and even prepare cameras to take pictures one by one.

Each faulty motor is dismantled and subjected to a series of careful inspections to analyze the cause. A large number of technicians are busy.

There was no sign of stopping until the evening, and even dinner was delivered to the workshop, and everyone continued to work after hastily eating.

It was a sleepless night.

In the morning, some employees who came to work early were shocked to find that Chief Engineer Xie had not slept all night, and they were still working there.

Each motor was disassembled, each part was carefully inspected, measured, recorded relevant data, etc., Xie Zhenhua and a large group of technicians were busy from yesterday afternoon to this morning.

Everyone was very tired on their faces, and Xie Zhenhua's eyes were even bloodshot, and the situation was even more not optimistic, which could be seen from the solemnity on Xie Zhenhua's face.

As the chief engineer, Xie Zhenhua didn't know where the problem was, so he could only instruct everyone to record the data accurately, and he might have to organize everyone to conduct a series of analyses and even a series of simulations.

It was now the mid-to-late nineties, and it was impossible to simulate it on a computer, so we had to adopt the "dirt method", manufacturing some parts according to the size of the faulty parts, assembling them together, and reproducing the faults.

It takes time and cycles.

Xie Zhenhua felt a lot of pressure, and even prayed in his heart, hoping that there would be no similar failures outside in the future, and even if they did, at least they would be less frequent.

"Chief Engineer Xie, go and take a break. ”

The technical minister of the Red Star Factory, seeing that Xie Zhenhua looked haggard, couldn't help but remind him with concern.

Xie Zhenhua sighed and said, "Where can I rest, I haven't found the problem yet!"

"Mr. Xie, go and rest, you are no younger than us, just leave the matter here to us. A young technician said.

Xie Zhenhua is indeed tired.

But he still insisted on working until noon, and after a hasty lunch, he returned to his office and squinted a little on the sofa, just taking a nap for less than an hour.

After waking up, Xie Zhenhua prepared to go to the assembly workshop again.

"Knock, knock, knock. ”

Outside the office door, when I knocked on the door, Xie Zhenhua's assistant Xiao Zhang came in with the brewed coffee and said softly: "Leader, you drink a cup of coffee to refresh yourself." ”

Xiao Zhang originally wanted to say, leader, you stayed up all night yesterday, and you must rest again, otherwise your body will not be able to bear it.

But he has not followed Xie Zhenhua for a short time, he knows Xie Zhenhua's character, swallows the words that come to his mouth, and instead makes a cup of coffee to give Xie Zhenhua a refreshment.

Xie Zhenhua picked up the coffee, took a sip gently, and asked, "I've been busy with the failure of the main cooling motor, has there been anything in the past two days?"

Xiao Zhang said: "Leader, there is nothing to do. ”

After finishing speaking, Xiao Zhang remembered something and wanted to open his mouth to say more, but after looking at Xie Zhenhua, he still held back.

Xie Zhenhua said: "Xiao Zhang, you can say anything about it." ”

Only then did Xiao Zhang tell the story. After listening to this, Xie Zhenhua was stunned for a while, and thought in his heart, no, there is such a thing!

……….
