Du Xiangyang still wanted to speak, but suddenly a loud shout sounded in his ears: "Isn't it necessary to thoroughly investigate the cause of the accident? Lao Hu, your equipment department should start now to find out for him!"

But it was the factory director Xiang Lixin.

Ever since he heard Hu Changzheng's report that it would take three months at the earliest for the thermal relay accessories from Sarem Company to be delivered, Xiang Lixin had been on the verge of going berserk, but he was concerned about his identity and suppressed it.

You know, this order with an annual foreign exchange income of nearly one million U.S. dollars was obtained by an old leader of the Heavy Industry Department with great pains. Originally, the provincial foreign trade company was going to hand over this order to a long-term relationship account of theirs.

, in the end it was the old leader who went to the office of the general manager of the provincial foreign trade company and patted the table before winning the order from Xiang Lixin.

Originally, according to Xiang Lixin's plan, as long as this order could be successfully won, with the dazzling achievement of one million US dollars in foreign exchange earnings, and the old leader would come forward to promote it, he could definitely take another step in his career and return to the Department of Heavy Industry.

It is not impossible to become a deputy director, or even to be bolder, to serve as a deputy mayor in Jiannan.

After all, according to the foreign exchange settlement regulations of Zhongtian Province, the annual foreign exchange quota of nearly one million U.S. dollars is divided between the Department of Heavy Industry and the Jian'an District. The Jian'an City will take away 70% of the foreign exchange quota, and the benefits obtained are much higher.

30% from the Department of Heavy Industry.

However, his plan came to nothing with the strike of the CNC machine tool from Sarem, France, in the metalworking workshop.

What’s even more frightening is that the old leader will retire next year, and the only time left for him to shine is less than a year. If he misses this excellent opportunity, Xiang Lixin will probably spend his whole life working hard.

The director-level position of the factory director was wasted...

So when he saw Qian Hongqi bringing Fan Xiaobin, the culprit who ruined his career dream, in front of him, he really had the urge to rush up and strangle Fan Xiaobin to death on the spot. The reason why he asked Qian Hongqi to take Fan Xiaobin back to the Security Department for interrogation

, just because he was afraid that if Fan Xiaobin stayed in front of him for a long time, he would not be able to control his emotions and do something rude.

However, he did not expect that Fan Xiaobin, the brother-in-law surnamed Guo, did not repent for Fan Xiaobin. Instead, he kept nagging at the side and even threatened to complain to the Department of Heavy Industry and the Jiannan Municipal Government. This made Xiang Lixin completely lose control of his emotions.

control:

"Hu Changzheng, you must thoroughly investigate the cause of the accident tonight and draw up the conclusion of the accident appraisal report! In any case, Fan Xiaobin is an employee of our factory, and we cannot let him go to jail in a daze under any circumstances. We must

Give him a clear explanation!"

Fan Xiaobin listened on the side, and his body that finally stood firm became weak again. He pulled Guo Yonghe's arm with his hand and said plainly: "Brother-in-law..."

"Don't worry, it's okay. I'll take care of everything."

Guo Yonghe waved his hand to Fan Xiaobin, indicating that there was no need to panic.

But how can Fan Xiaobin not panic? You know, what Guo Yonghe said is certain. He is just a small technician who works as a substitute in the biotechnology department of the internal parts factory. He can work with Xiang Lixin, Hu Changzheng, Fang Yunlei, and Qian Hongqi.

Do the leaders of Zhonghe Heavy Machinery Factory resist?

What's more, the Sarem CNC machine tool was actually broken by him after doing private work. This cannot be denied at all.

But what can he do if he doesn't believe Guo Yonghe at this moment? Guo Yonghe is the only straw he can grasp at the moment. Even if he knows it is useless, he still has to hold it firmly in his hands...

Seeing Xiang Lixin's harsh words, Hu Changzheng did not dare to hesitate anymore and immediately replied:

"Yes! Director, our equipment department will take action now. Even if we stay up all night, we will definitely find out the cause of the thermal relay burning out!"

Although he answered like this, standing in front of the Sarem CNC machine tool, Hu Changzheng felt worried.

The Sarem CNC machine tool was a new piece of equipment introduced into the factory last year. As the head of the equipment department, although he participated in the technical training provided by Sarem Company, he knew his own business, and in fact he only had two knives.

level.

This is not to say that Hu Changzheng's technical level is not good.

In fact, Hu Changzheng's attainments in machinery are quite impressive, otherwise it would be impossible for him to serve as the chief of the equipment section in a large department-affiliated factory like the Heavy Machinery Factory.

The problem is with the electronic circuit.

When the training engineer of Sarem Company talked about the mechanical part of CNC machine tools, Hu Changzheng basically understood every point, and there was no obstacle to learning.

But when the training engineer of Sarem Company talked about the circuit board of the CNC machine tool, Hu Changzheng's thinking began to lag, and he could not keep up with the train of thought of the training engineer of Sarem Company.

There is no way, electronic circuits have always been the weakness of veteran technicians like Hu Changzheng. For this technical training of Sarem Company, Hu Changzheng also worked hard to learn electronic circuits by himself for a period of time, but after the training started, he

I found that my understanding of electronics was still at a relatively basic stage, and I couldn't understand the explanations given by the training engineers from Sarem Company, especially when it came to inherited circuits.

In the end, the training engineers of Sarem Company tried their best, but Hu Changzheng could barely understand the general functions of the circuit board of this CNC machine tool. In other aspects, Hu Changzheng could only refer to the operation and use manual of the CNC machine tool mechanically.

Do it.

For example, the burnout of the thermal relay this time was obviously a problem with the integrated control circuit, but it was difficult for him to speculate on the specific cause, and the operation and use manual of Sarem Company only briefly listed the faults.

The signal prompts did not clearly explain the reasons behind them.

So although he answered Xiang Lixin happily at this time, he didn't know where to start to check the fault of the thermal relay.

Guo Yonghe saw Hu Changzheng standing in front of the machine tool, but did not take action. How could he not guess the reason?

When he was dealing with imported CNC machine tools in his previous life, he often saw the embarrassment of old-school technicians who were helpless in front of imported CNC machine tools.

However, he came here this time to solve the problem for Fan Xiaobin, not to see Hu Changzheng's embarrassment, so he reminded him:

"Chief Hu, based on my experience, if the thermal relay of a CNC machine tool burns out, it is probably a problem with the servo motor of the machine tool servo system. I suggest you start with the servo motor of the machine tool servo system first!"

One word awakens the dreamer.

"Yes, yes, there is probably something wrong with the servo motor!"

Hu Changzheng reacted immediately. He vaguely remembered that the training engineer of Sarem Company had talked about the relationship between the control circuit of the servo system and the thermal relay, so he immediately ordered the technicians in the equipment department to dismantle the casing and remove the servo motor.

examine.

Sure enough, as Guo Yonghe speculated, there were obvious traces of water stains on the servo motor...
