Chapter 27: Another Possibility

Seeing the water stains on the servo motor shell, Hu Changzheng couldn't help but glance at Guo Yonghe in surprise.

He really didn't expect that Guo Yonghe and a small technician in an internal distribution factory would have such a deep accomplishment in importing CNC machine tools, just by seeing the thermal relay burned out, he could speculate that it was likely that there was a problem with the servo motor of the servo system.

It's no wonder that this Guo Yonghe dared to go to the heavy machinery factory to stand on the platform for Fan Xiaobin, it turned out that he really had a few brushes!

Seeing that there may really be a problem with the servo motor, how could Hu Changzheng miss this opportunity? He personally went into battle, took the tools and equipment to disassemble the servo motor, and prepared to check the circuit and motor of the servo motor.

For electronic numerical control, although he Hu Changzheng is a second knife, but specifically in terms of mechanical and electrical, he Hu Changzheng is a good hand, otherwise how can he sit on the throne of the head of the equipment section of the heavy machinery factory for nearly ten years?

Soon, Hu Changzheng completed the inspection of the internal circuit and motor part of the servo motor.

It turned out that not only the external casing of the servo motor had water stains, but also the inside of the servo motor had water ingress, and both the coil and the motor were wet with obvious water stains.

Technicians always sympathize with each other, even if Hu Changzheng was not used to Guo Yonghe before, his attitude towards Guo Yonghe at this time couldn't help but change greatly, he stood up and said to Guo Yonghe: "Technician Guo, your guess is right, sure enough, there is a problem with the servo motor." ”

Speaking of this, he hesitated for a moment before he said: "It's just that I'm not sure a little, why does water ingress into the servo motor cause the thermal relay to burn out?" What's the connection? ”

Hearing Hu Changzheng raise this question, Guo Yonghe couldn't help but look at him with admiration.

As the section chief of the equipment section of the Heavy Machinery Factory, Hu Changzheng could actually not ask him this question. Even if you want to ask him this question, you can completely avoid Xiang Lixin, Fang Yunlei, Qian Hongqi, and other leaders of the heavy machinery factory, and ask him for advice in private.

However, Hu Changzheng did not care about his own face, and when the leaders of these large and small leaders of the heavy machine factory asked for advice from him, it can be seen that he was obsessed with technical problems.

"It's simple."

Guo Yonghe said: "After the servo motor enters the water, the output force becomes smaller, the current increases, and the permanent magnet is temporarily demagnetized. Therefore, when the power is applied, the circuit loses the protection of the permanent magnet, and the current passing through it is too large, which causes the thermal relay to protect the cooling pump motor to burn out. ”

"Thank you Technician Guo for your advice!"

Hu Changzheng thanked Guo Yonghe.

In fact, he also speculated like this in his heart, but he wasn't sure if his guess was correct, and at this time, he heard the same answer from Guo Yonghe's mouth, and a stone in his heart finally fell to the ground.

At least in the future, when he encounters a similar failure, he can judge the cause as soon as possible.

Seeing Guo Yonghe in the limelight, Du Xiangyang was extremely unhappy.

He proposed to Qian Hongqi to let Guo Yonghe come over, but Guo Yonghe was to take the blame, not to let Guo Yonghe be in the limelight, and he couldn't let this dog thing perform anymore. Otherwise, even if Fan Xiaobin is sentenced to prison in the end, Guo Yonghe's miraculous performance in the Heavy Machinery Factory will be spread, and then these will become the capital he bragged about in front of Fan Xiaolei and Wang Cailing, maybe Wang Cailing and Fan Xiaolei will ignore his previous big package, saying that they promise not to let Fan Xiaobin go to prison......

"Guo Yonghe,"

Du Xiangyang said loudly: "Before I asked you to persuade Fan Xiaobin to admit his guilt obediently, you are unwilling, you have to do more, and insist on finding out the cause of the thermal relay burning."

"Now that we've found out what caused the thermal relay to burn out, what can we do? Even if the thermal relay burns out due to water ingress into the servo motor of the servo system, what does this prove? Isn't all this caused by Fan Xiaobin stealing CNC machine tools for private work? ”

Although Xiang Lixin was surprised by Guo Yonghe's technical literacy just now, this could not dilute the slightest resentment and disgust towards Fan Xiaobin.

Even if Guo Yonghe's technical level is better than that of the maintenance engineers of Sarem, so what? Will he be able to conjure up a thermal relay on the spot and get the CNC machine back to work?

As long as the CNC machine tool can't resume work, and there is no way to process 500 precision gears before the day after tomorrow, everything is nonsense. Since his career as a new official is destined to stop at the threshold of department-level cadres, then Fan Xiaobin, who miserably harmed him, must pay the price!

"Old Hu,"

He ignored Guo Yonghe, but said to Hu Changzheng: "Since it has been found that it is the problem of the servo motor, the conclusion of the accident report can be made now, right?" ”

Hu Changzheng glanced at Guo Yonghe, nodded in embarrassment, and said: "Factory director, it should be able to be done, this accident is ......"

But before he finished speaking, he was interrupted by Guo Yonghe again.

"No, Section Chief Hu, the conclusion of the accident report can't be made yet!"

Guo Yonghe said: "Now we need to further find out what caused the servo motor to enter the water!" ”

What? What causes water ingress into the servo motor?

No matter how good Xiang Lixin's cultivation is, he also wants to rush up to give Guo Yonghe a kick.

Are you giving Matryoshka dolls here? Ring by ring, endlessly, right?

Okay, well, since you want to play, Lao Tzu will play with you!

I'll see how long you can get it!

"Old Hu!"

Xiang Lixin waved his hand and said: "Then you can do another inspection to see what is causing the servo motor to enter the water!" ”

What causes water ingress into the servo motor?

Hu Changzheng made it difficult again.

According to the requirements of the French Sarem company, the working environment of this Sarem CNC machine tool is very strictly controlled, not to mention water, even the dust is strictly controlled.

Du Xiangyang on the side laughed:

"How does the servo motor get water? It's easy! It must have been Fan Xiaobin who wiped the servo center shell with a wet rag with water, which caused the servo motor to enter the water! ”

"No, I absolutely don't!"

Fan Xiaobin shouted on the side, "I have received strict training in the workshop, how can I do the stupid thing of wiping the shell of the servo center of the CNC machine tool with a wet rag?" ”

"Huh!"

Du Xiangyang sneered, "You said that if you don't have it, there will be no more?" Who can prove it? After getting off work this afternoon, in addition to you, there is no second person who has touched this CNC machine, you can explain it to everyone, if you didn't wipe the servo center shell with a wet rag, then how did the servo motor get into the water? ”

Fan Xiaobin was speechless when questioned, stammering, and didn't know what to say.

At this time, Guo Yonghe sneered on the side, patted the electrical control cabinet of the CNC machine tool with his hand, and said to Du Xiangyang: "Du Xiangyang, will there be another possibility?" ”
