Hu Changzheng did not expect that Guo Yonghe recognized this thing as the three-phase AC thermal relay of the Sarem CNC machine tool with just a quick glance, and he was also able to accurately explain the main function of this three-phase AC thermal relay.

It protects the cooling pump motor of the machine tool from overload.

He was stunned for a few seconds, then nodded and said:

"Yes, it's the thermal relay that's broken!"

Then he asked his technician to bring a document and handed it to Guo Yonghe, "Technician Guo, this is the maintenance record of our equipment department on this Sarem CNC machine tool this afternoon.

"Take it and take a look. Does this maintenance record clearly state that this Sarem CNC machine tool was still operating in perfect condition in the afternoon?"

Guo Yonghe took the maintenance record and looked through it carefully. Indeed, as Hu Changzheng said, the maintenance record stated that starting at two o'clock in the afternoon, the equipment department technicians performed routine maintenance on the Sarem CNC machine tool, and the maintenance work continued until the afternoon.

It ended at 3:30, and at the end, the Sarem CNC machine tool was running in good condition.

"right!"

He nodded and said to Hu Changzheng: "This maintenance record can indeed prove that this Sarem CNC machine tool can operate normally this afternoon."

In fact, without this maintenance record, Guo Yonghe had to admit that the Sarem CNC machine tool was still operating normally in the afternoon.

Because if its operating status is abnormal, Fan Xiaobin will not be able to use it to do personal work after get off work.

"Technician Guo, isn't this necessary?"

Hu Changzheng said: "This Sarem CNC machine tool was still running normally in the afternoon, but after Fan Xiaobin used it to do private work after work, the thermal relay on the machine tool was burned out. It was obvious that Fan Xiaobin was using it secretly.

It was burned out while using the machine tool.

"It is for this reason that our Equipment Department has listed Fan Xiaobin as the person responsible for this machine tool accident. As Fan Xiaobin's family member, if you have no objection to this, please advise Fan Xiaobin to cooperate later.

Sign your name on the appraisal form."

Guo Yonghe frowned and looked at the maintenance records in his hand.

On the way here, I asked Fan Xiaobin about every detail of how he operated the machine tool. According to what Fan Xiaobin told me, none of his operating behaviors could cause the thermal relay of the Sarem CNC machine tool to be burned.

bad.

There must be something wrong here.

"Chief Hu,"

Guo Yonghe shook his head and said, "I think it is too hasty and arbitrary to judge that Fan Xiaobin is responsible for this machine tool accident based on this maintenance record and this burned thermal relay."

"Have you investigated clearly what caused this thermal relay to be burned?"

What caused this thermal relay to be burned?

Hu Changzheng couldn't help but be stunned.

At six o'clock in the evening, the night shift operator of the Sarem CNC machine tool in the metalworking workshop arrived and prepared to start processing precision gears according to the drawings provided by the technical department.

However, after pressing the start switch, there was an abnormal "pop" sound from the machine tool, then the machine tool stopped running, and the servo system began to alarm frantically.

After hearing the news, Hu Changzheng immediately led the technicians from the equipment department to the scene. According to the alarm prompt of the servo system, it was quickly determined that the thermal relay was faulty. He asked the technicians to remove the thermal relay for inspection and found that the thermal relay had been burned by the current.

, completely lost the function of protecting the cooling pump motor, and the Sarem CNC machine tool also stopped working because of this.

Hu Changzheng felt numb all over. The factory director Xiang Lixin had just held a meeting with them in the afternoon. Why didn't he understand what the strike on the Sarem CNC machine tool meant at this time?

While he asked Fang Yunlei, the director of the metalworking workshop, to investigate whether anyone had touched the Sarem machine tool after work, he ran back to the factory office, made an international long-distance call, and spoke to Sarem's Asian after-sales service in half-baked English.

It took more than half an hour to contact the center, and finally I communicated with the customer service staff on duty at the Sarem After-Sales Center and understood that it would take three months at the fastest to ship a new thermal relay to China.

He immediately rushed back to the metalworking workshop and reported to the factory director Xiang Lixin who rushed to the scene after hearing the news. The process did not leave him enough time to think about what caused the thermal relay to be burned.

.

He did not expect that Fan Xiaobin, his brother-in-law who worked as a technician in an internal parts factory, would ask him this question.

"Technician Guo,"

Hu Changzheng hesitated for a moment and decided to tell the truth, "Because things happened in a hurry, our equipment department can only confirm that the thermal relay was burned out. As for what caused the thermal relay to be burned out, we still need to wait."

We will be able to figure it out after further inspection of the CNC machine tool."

"Isn't this enough?"

Guo Yonghe shrugged his shoulders and returned Hu Changzheng's previous words.

He said: "Chief Hu, you didn't even check the cause of the thermal relay being burned out, so you just hurriedly put the blame for this machine tool accident on Fan Xiaobin. This is not arbitrary or hasty.

What is it again?"

Hu Changzheng was speechless and didn't know what to say.

Indeed, as Guo Yonghe said, it is a bit arbitrary and hasty to identify Fan Xiaobin as the person responsible for this machine tool accident before figuring out why the thermal relay was burned out.

But if you don't throw Fan Xiaobin out, how can you face Xiang Lixin, who is in a state of rage because he lost a million-dollar foreign exchange order?

No matter it was Fang Yunlei or Hu Changzheng, their thin shoulders were not enough to bear Xiang Lixin's immense anger.

What's more, no matter what the reason is for the thermal relay to burn out, the most fundamental reason is that Fan Xiaobin misappropriated the machine tool for private work. Although it is against procedure to determine that Fan Xiaobin is responsible for the machine tool accident before the cause of the fault is found out, it is against the procedures.

Not unjustly.

"Guo Yonghe,"

At this time, Du Xiangyang, who had been silent, stood up and said,

"What you said is a bit confusing. The reason why the thermal relay of the CNC machine tool was burned out was not because Fan Xiaobin was secretly doing private work? Whether or not the reason why the thermal relay was burned out will not affect Fan Xiaobin's responsibility for this incident.

Qualification of liability for machine tool accidents!”

"Yes, that's what it means!"

Hu Changzheng nodded repeatedly.

The gold-plated cadres sent by the Heavy Industry Department were indeed different. They blocked Guo Yonghe as soon as he opened his mouth.

"hehe!"

Guo Yonghe glanced at Du Xiangyang with disdain, shook his head and said with a smile:

"Du Xiangyang, you are still a technical cadre assigned by the Provincial Department of Heavy Industry. Don't you understand that according to procedures, you cannot characterize the accident before the cause of the accident is thoroughly investigated?

"Since the accident cannot be characterized, how can we determine that Fan Xiaobin is the person responsible for the machine tool accident?

"Of course, as for his violation of factory regulations and stealing equipment for private work, you can handle it as you should according to the factory regulations. We as family members have absolutely no objection.

"But if we arbitrarily and hastily identify Fan Xiaobin as the person responsible for the accident without investigating why the thermal relay burned out, our family members will definitely not agree! We will definitely report your violation of procedures to the Jiannan Municipal Government.

, complained to the Provincial Department of Heavy Industry!”
