Reborn Industrial Tycoon

Huang Aihua looked at Li Weidong in surprise. Before that, Huang Aihua only regarded Li Weidong as Zhao Guodong's follower and was something he didn't need to care about at all. Huang Aihua didn't even write down Li Weidong's name.

However, Li Weidong was able to accurately name Sakurada Co., Ltd., which surprised Huang Aihua.

At that time, the only foreign brands that Chinese people could name were Panasonic, Sharp, Sanyo and other home appliance brands, and they were almost completely ignorant of other foreign brands. A name like "Sakuda Co., Ltd." must be from the field of mechanical equipment.

Only experts can know.

"Does this little comrade know anything about mechanical equipment?" Huang Aihua asked.

"This little comrade? He didn't remember my name." Li Weidong complained in his heart.

Then Li Weidong nodded helplessly and said humbly: "I just know a little bit about it. Under normal circumstances, the common faults of hydraulic pressure are nothing more than vibration and noise, hydraulic shock, hydraulic oil leakage, crawling during operation, valve core

Stuck and overheated.”

"It seems that this young comrade is an expert!" Huang Aihua said.

However, even though Li Weidong was an expert in hydraulics, Huang Aihua didn't take it to heart. Yankuang's technical department had several mechanical engineers who were all experts in hydraulics.

Li Weidong went on to say: "If I guessed correctly, the failure of your hydraulic equipment should be that the oil suction filter is clogged, right?"

After saying this, Huang Aihua's expression became uneasy again. He nodded seriously: "There is indeed a situation where the oil suction filter is clogged."

"There are also grinding of hydraulic cylinder components, right?" Li Weidong asked again.

Huang Aihua almost stood up from his seat. He nodded more solemnly: "Yes, there are also wear and tear on the hydraulic cylinder components!"

"The cause of the failure given by Sakurada Co., Ltd. is that the hydraulic piston rod will be corroded by coal particles and gas in the coal mine during the reciprocating motion of extension and retraction, causing contaminants to penetrate into the matching gap between the piston rod and the guide sleeve.

, further accelerated the wear of the hydraulic cylinder components, and caused the paint surface in the hydraulic tank to be corroded, causing the paint in the tank to fall off and clog the oil suction filter of the hydraulic pump." Li Weidong said slowly and calmly.

This time, Huang Aihua really couldn't sit still. What Li Weidong said was exactly the same as the cause of the failure given by Sakurada Co., Ltd.

The engineers of Sakurada Co., Ltd. came to this conclusion after studying the damaged hydraulic equipment. However, Li Weidong didn't even see the gate of the mining area. At the dining table of the guest house, he just guessed it based on Huang Aihua's few words.

identified the cause of the failure.

No matter how stupid Huang Aihua is, he can still see that the twenty-year-old young man in front of him is definitely not an ordinary person.

"Excuse me, comrade, oh, no, what is the name of this teacher?" Huang Aihua stood up and asked cautiously.

"His name is Li Weidong, and he is our treasure!" Zhao Guodong immediately introduced him from the side.

In fact, Zhao Guodong had already introduced Li Weidong when they first met, but Huang Aihua regarded Li Weidong as a passerby and didn't pay attention to him at all.

Now, in order to avoid embarrassment, Zhao Guodong once again introduced Li Weidong.

"It turns out to be Teacher Li." Huang Aihua nodded with a smile, and then said: "Guodong, your freight department is really amazing, and you can even be qualified to be a college student! In our Yankuang, only the technical department can be assigned to college students.

.”

Huang Aihua regarded Li Weidong as a college student. Huang Aihua felt that Li Weidong was so young and only a college student could understand mechanical technology so well and speak eloquently.

Zhao Guodong just laughed and did not deny it. Huang Aihua was praising Li Weidong. If he stood up and denied it, saying that Li Weidong was a junior high school graduate, wouldn't it be embarrassing for both parties, so he simply acquiesced.

In 1985, college students were the absolute pride of heaven. Even an old worker with twenty or thirty years of work experience would not be an exaggeration to call a college student "teacher so-and-so."

Li Weidong asked again: "Director Huang, Sakurada Company said it would help you upgrade your equipment. What is the equipment upgrade plan? Can you tell me?"

"Hey, don't mention it! When I talk about this plan, I get angry!" Huang Aihua sighed helplessly, and then said: "Sakurada Company didn't tell us how to upgrade the equipment at all. They said it was a trade secret.

It cannot be spread externally."

"If I don't tell you the equipment upgrade plan, how will they upgrade?" Li Weidong asked again.

"Sakurada Company will send engineers with tools to the site to help us upgrade, and they also put forward many requirements, such as good food and accommodation, reimbursement of round-trip travel expenses, food and drinks, etc., which is the most irritating

What's strange is that when they upgraded the equipment, they didn't allow our people to watch from the side!" Huang Aihua said angrily.

"This is too much!" Zhao Guodong took the lead in fighting the injustice.

Li Weidong looked calm. Such a request seemed normal to Li Weidong. Even at the beginning of the 21st century, when foreigners were invited to repair TBMs, they were still cordoned off from afar.

, don’t let the Chinese get close.

China's technology is lagging behind, and it cannot make what it needs by itself. If foreigners get stuck, they can only pinch their noses and recognize it. Foreigners also take advantage of China's lagging technology and use other tricks to steal money from China.

For example, adding some unnecessary things when selling equipment; for example, bullying you because you don't understand, and only selling the original version, and then making a fortune in the name of equipment upgrade; for example, leaving a backdoor in the maintenance of equipment, and if the equipment fails, it needs to be repaired.

, you will have to pay a sky-high maintenance fee.

Obviously, Yankuang was tricked by Sakurada Co., Ltd. in this way.

Huang Aihua took advantage of the drunkenness and cursed Sakurada Co., Ltd. for being black-hearted. Zhao Guodong next to him also followed suit. However, the two of them sang and cursed for a long time, but it did not help solve the problem.

Finally, Li Weidong said: "The working environment in the mine is indeed very complex. Coal particles will indeed cause contaminants to seep into the gap between the piston rod and the guide bushing. These small particles of coal are still somewhat hard, which will cause wear and tear on the hydraulic cylinder components.

, but this problem is not difficult to solve, you just need to install a protective cover.”

"Of course we have thought about installing protective sleeves. We have a rubber products factory in Yankuang, but the protective sleeves produced are not easy to use. The hydraulic piston rod has to expand and contract back and forth, and soot will still get inside over time.

"

Huang Aihua paused for a moment, then continued: "And engineers from Sakurada Co., Ltd. also said that the protective sleeve can only protect the hydraulic cylinder components to a certain extent, but contaminants will eventually enter the hydraulic tank, causing the paint in the tank to fall off and become clogged.

The oil suction filter of the hydraulic pump. Regarding this, our engineers have also tested it, and it is indeed true."

"Hehehe..." After hearing this, Li Weidong laughed.

"Hey! Teacher Li, why are you laughing? You think what I said is wrong? But our own engineers can't be wrong!" Huang Aihua said dissatisfied.

"Director Huang, you have been tricked by Sakurada Co., Ltd.!" Li Weidong said.
