"Technician Guo, if you want to calculate the fee standard for on-site maintenance by after-sales engineers of the French Sarem company, it is too high, at least 3,000 US dollars to start."

Xiang Lixin pondered for a moment and said, "I think it is more appropriate to calculate according to the standard of a newly purchased thermal relay."

"Our equipment department has contacted the French Sarem company, a piece of thermal relay quotation is 750 US dollars, plus the cost of mailing and customs clearance, only 1,000 US dollars, according to the current official exchange rate announced by the People's Bank of China, about 5,700 yuan, we will give you a whole amount, according to 5,800 yuan to calculate, how about it?"

"As long as you think it is appropriate to the factory director, I will definitely have no problem!" Guo Yonghe agreed with a smile.

He naturally has nothing to be dissatisfied with, while being able to send Du Xiangyang to the prison cell for five years, he can also get a huge income of 5,800 yuan, this trip can be described as a full harvest, and it is not in vain that he made a special trip to the heavy machinery factory.

"It's fine!"

Xiang Lixin nodded, but said again: "But Technician Guo, we can't only have rewards and no punishments. You must be happy that you have repaired that thermal relay, I can start machining precision gears here, and you also get a high maintenance fee on your side.

"But what if it can't be repaired? And what to do? The risk and return are equal, and there is no reason why you only enjoy the benefits after success, but do not have to bear the risks after failure.

"The heavy machinery factory is not my old word, and I always have to give an explanation to the superior leaders and the masses below!"

"Huh,"

Guo Yonghe laughed and said: "Xiang to the factory director, what you said is indeed reasonable, it is impossible for me to only enjoy the benefits and not take risks."

"Then let's do this, we can sign a maintenance agreement first, according to the principle of equal risk and return, if I repair the thermal relay, then your heavy machinery factory will pay me 5,800 yuan for the maintenance fee.

"If I can't fix the thermal relay, then I'll give your factory 5,800 yuan to compensate for the cost of the new thermal relay that your factory bought from the French company Sarem, what do you think?"

"That's no problem!"

Xiang Lixin nodded and said, "I did this just to give an explanation to the leaders above." In fact, as you know, what our factory urgently needs is to repair the thermal relay and let the Sarem CNC machine tool return to work, rather than caring about the purchase cost of thousands of spare parts. ”

"Well, I understand!" Guo Yonghe said.

"Then it was so happily decided!"

Xiang Lixin stretched out his hand to Guo Yonghe, "I'll let the director of the factory office draw up a maintenance agreement on the spot, and after we both sign it and take effect, you can start repairing the thermal relay!" ”

Before leading Guo Yonghe back to the Sarem CNC machine tool, he first asked the director of the factory office to draw up a maintenance agreement, and then said to Qian Hongqi: "Section Chief Qian, you first bring Comrade Du Xiangyang back to your department, and let him recall the maintenance of the electrical control cabinet of the Sarem CNC machine tool this afternoon, and we must figure out how the air conditioning water baffle is reversed!" ”

"What do you mean by that, Director Xiang?"

Du Xiangyang shouted on the side, "I am a temporary cadre sent by the Department of Heavy Industry, without the approval of the leaders of the Department of Heavy Industry, which of you dares to touch me?" ”

"Hehe, Chief Du, we don't plan to touch you!"

Xiang Lixin said with a smile, "It's just that the scene here is too chaotic, I'm afraid that you can't remember under what circumstances you installed the air conditioner baffle upside down, so let Section Chief Qian take you to a quiet place for you to recall." ”

As he spoke, he gestured at Qian Hongqi.

Qian Hongqi got Xiang Lixin's approval, where can he care if Du Xiangyang is a gold-plated cadre from the Heavy Industry Department, and immediately led several subordinates of the security department to pounce like wolves, regardless of Du Xiangyang's struggle and resistance, and took him out of the metalworking workshop site.

At this time, the director of the factory office also drafted the maintenance agreement according to Xiang Lixin's explanation and divided it into two parts, one to Xiang Lixin and one to Guo Yonghe.

Xiang Lixin reviewed it, saw that there was no problem, and signed his name on the agreement with a pen.

Guo Yonghe took it in his hand and studied it carefully, but he didn't find anything wrong, so he also took a pen and signed his name on the agreement in his hand, and immediately exchanged agreements with Xiang Lixin, and then signed his name on the agreement that had eased up, and carefully stuffed it into his pocket.

With this agreement, it is equivalent to saying that Du Xiangyang has been nailed to death on the charge of dereliction of duty.

The huge loss of state-owned assets of 5,800 yuan is not something that Du Xiangyang's thin shoulders can afford!

Xiang Lixin also signed his name on the exchange agreement, he handed over the agreement to the director of the factory office for safekeeping, and then said to Guo Yonghe: "Technician Guo, can you start repairing the thermal relay now?" ”

"That's it!"

Guo Yonghe nodded, asked Hu Changzheng to take the tools, directly used another ordinary machine tool as a workbench, took the broken thermal relay, and started on-site repairs.

"Technician Guo,"

Hu Changzheng stood aside, consciously acting as an apprentice to Guo Yonghe's delivery tools, while holding back the curiosity in his heart, he asked Guo Yonghe: "Can this thermal relay really be repaired?" How exactly are you going to fix this thermal relay? ”

"Hehe, of course you can fix it!"

Guo Yonghe laughed, pointed to the components on the thermal relay with tweezers, and said: "The full name of this thermal relay is a three-phase AC thermal relay, and there are three thermal elements on it, which are used to protect the cooling pump from overload."

"Generally speaking, a single current overload will only burn out one hot element, don't you think?"

Hu Changzheng looked in the direction pointed by Guo Yonghe and the tweezers, and sure enough, he found that this thermal relay had only burned out one thermal element.

"Technician Guo, these three thermal elements are connected in series with each other, and if one of the thermal elements is broken, there is no way to use it!" We don't have the corresponding thermal components in China, and the French Sarem company will not sell the thermal components separately, but only the entire thermal relay. ”

Hu Changzheng shook his head and said, "Without a thermal element, how are you going to repair it?" ”

"Huh,"

Guo Yonghe laughed again, led Hu Changzheng back to the front of the Sarem CNC machine tool, pointed to the cooling pump motor exposed after removing the thermal relay, and asked Hu Changzheng: "Section Chief Hu, if you take a closer look, how is the external wiring of this cooling pump motor connected?" ”

Hu Changzheng lowered his head and examined it carefully, then raised his head and said, "It is connected by a three-phase star." ”

"Section Chief Hu,"

Guo Yonghe reminded again: "Then do you remember what is the structure of the thermal relay that protects the AC motor of this three-phase star connection on the CNC machine tool in the Soviet Union?" ”

"CNC machines in the USSR?"

Hu Changzheng slapped his head and shouted: "The thermal relay on the Soviet-style CNC machine tool that protects the AC motor of the cooling pump seems to have only two thermal elements!" ”

"Hehe, that's right!"

Guo Yonghe said with a smile: "For this kind of three-phase star-connected AC motor, a thermal relay with two thermal elements is enough to protect it from overload. So now this thermal relay is broken a hot element is not too tight, we only need to short the burned out resistance thermal element, so that the other two resistance thermal elements keep unblocked, this thermal relay can resume work, take on the task of protecting the cooling pump motor! ”
