When Du Xiangyang saw Guo Yonghe patting the electrical control cabinet, his heart couldn't help but jump suddenly.

Because the maintenance work of the electrical control cabinet of the French Sarem CNC machine tool in the afternoon was undertaken by him.

Although the entire maintenance work was carried out in full accordance with the operation and use manual of the French Sarem company, there could be no problems, but Guo Yonghe and this dog thing suddenly patted the electrical control cabinet at this time, but Du Xiangyang could not help but be vigilant.

Just when Du Xiangyang was hesitating how to answer Guo Yonghe's words, Hu Changzheng couldn't wait on the side, and couldn't wait to ask:

"Technician Guo, what other possibilities are there, can you tell me?"

"Section Chief Hu,"

Guo Yonghe turned his head to look at Hu Changzheng, "What is the way of heat dissipation of the electrical control cabinet of this French Sarem CNC machine?" ”

The more advanced the CNC machine tool, the more electrical components are used in its electrical control cabinet, and these electrical components will emit a lot of heat when working, which will strictly affect the performance of the electrical components themselves.

Therefore, just as a high-performance computer chassis needs to install a heat dissipation device for heat dissipation, the electrical control cabinet of high-performance CNC machine tools also needs to install a special heat dissipation device for the normal use of the electrical control cabinet.

Generally speaking, there are three types of heat dissipation devices in electrical control cabinets: electric fans, heat exchangers and air conditioners. Among them, the air conditioner is the main heat dissipation device for the electrical control cabinet of imported CNC machine tools.

The same is true for the French Sajem CNC machine of the Heavy Machinery Factory, where a small air conditioner is installed in the electrical control cabinet to reduce the temperature in the control cabinet when the machine tool is working, so as to ensure the normal operation of the internal electrical components.

When Hu Changzheng heard Guo Yonghe say this, he reacted immediately, pointed to the electrical control cabinet with his finger, and said to Guo Yonghe: "Technician Guo, do you mean that there may be problems with the cooling and air conditioning in the electrical control cabinet?" ”

"There should be a possibility!"

Guo Yonghe nodded and said, "There is no water in the external environment of this Sarem CNC machine, and Fan Xiaobin said that he definitely did not wipe the shell of the servo system with a wet rag, so we can only guess whether there is a problem with the cooling air conditioner in the electrical control cabinet?" Because from the current point of view, the only possible source of water stains on the servo motor housing is the condensation generated by the cooling air conditioner in the electrical control cabinet! ”

"It's unlikely, isn't it?"

Hu Changzheng touched his chin with his hand, "According to the design of Sarem, the condensate generated by the cooling air conditioner in the electrical control cabinet is evaporated through the air duct on the evaporation side. And according to our experience in the use of this Sarem CNC machine for more than a year, there has never been a situation where the condensate of the cooling air conditioner has soaked into the servo system.

"What's more, this afternoon, the chief of our equipment department, Du also took matters into his own hands to maintain the electrical control cabinet."

"Yes!"

Du Xiangyang said: "I just maintained the electrical control cabinet this afternoon, and the maintenance is carried out in strict accordance with the machine tool operation and use manual of Sarem Company, and there will be absolutely no condensation from the cooling air conditioner dripping onto the servo motor shell!" ”

"Hehe, Du Xiangyang,"

Guo Yonghe laughed, "My speculation that the water stains on the servo motor shell may be caused by condensation of the cooling air conditioner only puts forward one possibility, and it does not necessarily say that this guess is correct."

As for whether the real reason is the case, it is very simple to verify, as long as the partition of the electrical control cabinet is disassembled, and the working condition of the cooling air conditioner can be seen.

"This is originally a very simple matter, Du Xiangyang, you won't be so weak that you don't dare to let Section Chief Hu disassemble the partition of the electrical control cabinet, right?"

Du Xiangyang didn't expect Guo Yonghe to be so sharp-tongued, so he directly forced him into a corner and couldn't move. Could he still admit to Guo Yonghe that he was just weak in his heart and didn't dare to let Hu Changzheng open the partition of the electrical control cabinet to verify the working condition of the cooling and air conditioning?

"Okay, okay, Section Chief Du, what are you doing with him in that lawsuit?"

Xiang Lixin said with a calm face on the side: "He wants to open the partition of the electrical control cabinet for verification, then open the partition of the electrical control cabinet for him to verify, and after the verification, what else can he say?" ”

Speaking of this, he looked at Guo Yonghe again: "Guo Yonghe, I will ask you one last word." If the partition of the electrical control cabinet is opened and it is verified that the water stains on the servo motor shell have nothing to do with the condensation of the cooling air conditioner, then the responsibility for this machine tool accident will be borne by Fan Xiaobin, will there be no more opinions? ”

"Of course!"

Guo Yonghe nodded and said: "If you disassemble the partition of the electrical control cabinet and confirm that the condensate of the cooling air conditioner will not drip onto the shell of the servo motor, then I can't think of any other reason, I can only think that Fan Xiaobin lied and accidentally wiped the servo system shell with a wet rag with water." ”

Seeing that Guo Yonghe had the intention of giving up on himself, Fan Xiaobin was frightened, tremblingly pulled Guo Yonghe's arm, and said mournfully: "Brother-in-law, I didn't lie......"

Guo Yonghe shook off Fan Xiaobin's arm: "You didn't lie, after opening the partition of the electrical control cabinet, you can be sure!" ”

Seeing that Guo Yonghe agreed to check the heat dissipation and air conditioning and then stopped continuing the matryoshka doll, this farce finally came to an end, Xiang Lixin no longer hesitated, waved at Hu Changzheng, and said: "Old Hu, open the partition of the electrical control cabinet!" ”

"Yes!"

Hu Changzheng answered, took the tool and went up to open the partition behind the electrical control cabinet, and the small air conditioner inside was exposed.

Then he held up a flashlight and shone it on the small air conditioner, and suddenly his face changed greatly, and he turned his head to Du Xiangyang, who was following behind him, and asked, "Section Chief Du, who installed the water baffle for cooling the air conditioner?" ”

Du Xiangyang had already seen the wind shield clearly, his face was like dust, and he said in a low voice: "Yes, I installed it." ”

"What's wrong?"

Xiang Lixin immediately rushed forward with a stride and asked loudly: "Section Chief Hu, what's wrong with the air conditioner water baffle?" ”

"It's reversed, it's completely reversed!"

Hu Changzheng pointed to the water baffle with his finger, and he was about to cry.

In order to prevent the wind speed of the evaporation channel from being too high and the condensate splashes out into the electrical control cabinet, Sarem has specially installed a water baffle in the evaporation side channel, so that the condensate can completely prevent the condensate from entering the electrical control cabinet.

But he didn't expect that Du Xiangyang, as the technical backbone of the Heavy Industry Department, would make such a stupid mistake and install the water baffle upside down when maintaining the electrical control cabinet......
