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

He really didn't expect that Guo Yonghe, a small technician in an in-house parts factory, was so knowledgeable in imported CNC machine tools. Just by seeing the thermal relay burned out, he could deduce that there was probably a problem with the servo motor of the servo system.

.

No wonder Guo Yonghe dared to go to the heavy machinery factory to stand up for Fan Xiaobin. It turns out that he really has a lot of skills!

Seeing that there might really be a problem with the servo motor, how could Hu Changzheng miss this opportunity? He personally took the tools and equipment to dismantle the servo motor and prepared to check the servo motor's circuit and motor.

Although he, Hu Changzheng, is a second-hand person in terms of electronic numerical control, when it comes to mechanical and electrical aspects, he, Hu Changzheng, is an expert. Otherwise, how could he have been able to sit on the throne of the equipment section chief of the heavy machinery factory for nearly ten years?

Woolen cloth?

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

The results proved that not only the outer casing of the servo motor had water stains, but also the inside of the servo motor had water. The coils and motor were both wet and had obvious water stains.

Technicians always sympathize with each other. Even if Hu Changzheng had disliked Guo Yonghe before, his attitude towards Guo Yonghe could not help but change a lot at this time. He stood up and said to Guo Yonghe: "Technician Guo, your guess is good. Sure enough,

There is something wrong with the servo motor."

Having said this, he hesitated for a moment and then said: "I'm just a little unsure. Why does water in the servo motor cause the thermal relay to burn out? What is the connection between this?"

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 actually did not have to ask him this question. Even if he wanted to ask him this question, he could avoid Xiang Lixin, Fang Yunlei, Qian Hongqi and other leaders of the heavy machinery factory.

, ask him for advice in private situations.

However, Hu Changzheng did not take his own face into account and asked for advice in front of the leaders of the heavy machinery factory, which shows his obsession with technical issues.

"The reason is very simple."

Guo Yonghe said: "After water enters the servo motor, the output force becomes smaller and the current increases, causing the permanent magnet to be temporarily demagnetized. Therefore, when the power is energized, the circuit loses the protection of the permanent magnet, and the current passing through is too large, causing protection

The thermal relay of the cooling pump motor is burned 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 was not sure whether his speculation was correct. At this time, he heard the same answer from Guo Yonghe, and a stone in his heart finally fell to the ground.

At the very least, if he encounters a similar fault in the future, he will be able to determine the cause immediately.

Seeing Guo Yonghe stealing the show, Du Xiangyang felt extremely unhappy.

He proposed to Qian Hongqi that Guo Yonghe should come over. Guo Yonghe was the one who took the blame. He did not let Guo Yonghe come to the limelight. He could not let this piece of shit perform anymore. Otherwise, even if Fan Xiaobin was sentenced to jail in the end, Guo Yonghe

This miraculous performance in the heavy machinery factory will also spread, and then it will become his bragging rights in front of Fan Xiaolei and Wang Cailing. Maybe Wang Cailing and Fan Xiaolei will ignore his previous big package and say that he guarantees

We will not let Fan Xiaobin go to jail...

"Guo Yonghe,"

Du Xiangyang said aloud: "I asked you to persuade Fan Xiaobin to plead guilty before, but you didn't want to, so you insisted on finding out the cause of the burnout of the thermal relay.

"Now that we have found out the cause of the burnout of the thermal relay, what can we do? Even if the burnout of the thermal relay is caused by water entering the servo motor of the servo system, what does this prove? Isn't it all Fan Xiaobin's secret use of CNC machine tools?

Is it caused by private work?”

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

Even if Guo Yonghe's technical level is better than that of Sarem Company's maintenance engineers, so what? Can he change a thermal relay on site to restore the CNC machine tool to work?

As long as the CNC machine tool cannot resume work and cannot process 500 precision gears before the day after tomorrow, everything will be nonsense. Since his career to Xiang Lixin is destined to stop at the threshold of a department-level cadre, then Fan Xiaobin, who caused him misfortune, will

You must pay the price!

"Lao Hu,"

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

Hu Changzheng glanced at Guo Yonghe, nodded awkwardly, and said: "Director, it should be possible to make it. This accident is..."

But before he could finish his sentence, he was interrupted again by Guo Yonghe.

"No, Chief Hu, the conclusion of the accident report cannot be made yet!"

Guo Yonghe said: "We still need to further find out what caused the servo motor to get water!"

What? Want to find out what causes water in the servo motor?

No matter how well-mannered Xiang Lixin is, he still wants to rush forward and give Guo Yonghe a kick.

Are you here making matryoshka dolls for me? Doing it one ring after another, endlessly, right?

Okay, okay, since you want to play, I will play with you!

Let's see how long you can get it!

"Old Hu!"

Xiang Lixin waved his hand and said, "Then you should do another check to see what caused the servo motor to get water!"

What causes water to enter the servo motor?

Hu Changzheng did it 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 dust is strictly controlled.

Du Xiangyang on the side laughed:

"How did the servo motor get water? It's very simple! Fan Xiaobin must have used a wet rag with water to wipe the servo center housing, which caused water to enter the servo motor!"

"No, I absolutely didn't!"

Fan Xiaobin shouted from the side, "I have received strict training in the workshop, how could I do such a stupid thing as wiping the outer shell of the CNC machine tool servo center with a wet rag?"

"hehe!"

Du Xiangyang sneered, "You said it doesn't exist? Who can prove it? After work this afternoon, no one else has touched this CNC machine tool except you. Please explain it to everyone. If it wasn't you

I wiped the servo center housing with a wet rag, so how did water get into the servo motor?"

Fan Xiaobin was speechless and speechless when questioned, not knowing what to say.

At this time, Guo Yonghe sneered from the side, patted the electrical control cabinet of the CNC machine tool with his hand, and said to Du Xiangyang: "Du Xiangyang, is there another possibility?"
Chapter completed!
