Rebirth of the Industrial Tycoon

  Chapter 70 Subject to others

  Huang Aihua looked at Li Weidong in surprise. Before that, Huang Aihua only regarded Li Weidong as Zhao Guodong’s follower, and he didn’t even care about it. 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 Chinese people, the only foreign brands that can be named are probably only Panasonic, Sharp, Sanyo and other home appliance brands, and they almost don’t know anything about other foreign brands. A name like "Sakurada Co., Ltd." can only be known by experts in the field of machinery and equipment.

  "This little comrade still knows machinery and equipment?" Huang Aihua asked.

  "This little comrade? Didn't remember my name again." Li Weidong said in his heart.

Then Li Weidong nodded helplessly, and said with a humble expression: "I just know a little bit. Under normal circumstances, hydraulic pressure often fails, nothing more than vibration and noise, hydraulic shock, hydraulic oil leakage, crawling during operation, and spool. It's stuck and the temperature is too high."

   "It seems that this little comrade is an insider!" Huang Aihua said.

  However, even if Li Weidong is an expert in hydraulics, Huang Aihua did not take it to heart. There are several mechanical engineers in Yankuang's technical department, all of whom are experts in hydraulics.

  Li Weidong went on to say, “If I’m not mistaken, the failure of your hydraulic equipment should be due to the clogging of the suction filter, right?”

  Said this sentence, Huang Aihua's expression became unstable again, and he nodded seriously: "There is indeed a clogging of the oil suction filter."

   "There are also hydraulic cylinder components that are ground, right?" Li Weidong asked again.

  Huang Aihua almost got up from his seat, he nodded more solemnly: "Yes, there are still hydraulic cylinder components worn out!"

"The cause of the failure given by Sakurata Co., Ltd. is that the hydraulic piston rod will be corroded by coal particles and gas in the coal mine during the reciprocating movement of the hydraulic piston rod, which will cause pollutants to penetrate into the gap between the piston rod and the guide sleeve. , Further accelerated the wear of hydraulic cylinder components, and caused corrosion of the paint surface in the hydraulic oil tank, causing the paint in the oil tank to fall off, clogging the suction filter of the hydraulic pump." Li Weidong said calmly.

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

The engineer of Sakurada Co., Ltd. came to this conclusion after studying the damaged hydraulic equipment, and Li Weidong didn’t even see the gate of the mining area. On the dining table of this guest house, he guessed it only with a few words from Huang Aihua. The cause of the failure was found.

  No matter how stupid Huang Aihua is, he can see that the young man in his 20s is definitely not an ordinary person.

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

   "His name is Li Weidong, but our baby!" Zhao Guodong introduced immediately.

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

  To avoid embarrassment, Zhao Guodong once again introduced Li Weidong.

"It turned out to be Teacher Li." Huang Aihua smiled and nodded, and then said: "Guodong, your freight forwarding office is really amazing, and it can be equipped with college students! In 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 that only a college student could have such an understanding of mechanical technology.

  Zhao Guodong just chuckled, but did not deny it. Huang Aihua is praising Li Weidong. If he stands up and denies it, saying that Li Weidong is a junior high school graduate, wouldn't it embarrass both sides, so he simply acquiesced in it.

  In 1985, college students were the absolute favorites of heaven. Even veteran workers with 20 or 30 years of work experience would not be an exaggeration to call college students "Teacher so and so."

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

"Hey, don't mention it! When it comes to this plan, I feel angry!" Huang Aihua sighed helplessly, and then said: "Sakurada does not tell us how to upgrade the equipment at all. They say it is a trade secret. It can't be passed on."

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

"Sakurada will send engineers and bring tools to help us upgrade on site, and they also put forward many requirements, such as eating and living well, reimbursement for round-trip travel expenses, and eating and drinking. The thing is, when they upgrade the equipment, our people are not allowed to watch it!" Huang Aihua said angrily.

   "This is too much!" Zhao Guodong took the lead to fight the injustice.

  Li Weidong has a calm face. Such a request is a normal thing in Li Weidong's view. Even at the beginning of the 21st century, when foreigners were invited to repair the shield machine, they would pull the cordon from far away to keep the Chinese away.

  China's technology is backward, and the things needed can’t be made by itself, and even if the neck is stuck by a foreigner, it can only be recognized by the nose. Foreigners are also taking advantage of China's technological backwardness to dig money out of China in exchange for tricks.

For example, add some non-essential things when selling equipment; for example, bullying you do not understand, only sell the original version, and then make a fortune in the name of equipment upgrade; such as leaving a back door in the maintenance of equipment, if the equipment fails to be repaired , It is necessary to pay sky-high maintenance costs.

  Obviously, Yankuang was used by this Sakurada Co., Ltd. to make routines in this way.

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

In the end, Li Weidong said: "The working environment in the mine is indeed very complicated. Coal particles will indeed cause pollutants to penetrate into the gap between the piston rod and the guide sleeve. This small particle of coal is still somewhat hard and will cause the hydraulic cylinder components to wear. , But this problem is not difficult to solve. It only needs to install a protective cover."

"Of course we thought about installing a protective cover. We have a rubber product factory in Yankuang, but the protective cover made is not easy to use. The hydraulic piston rod needs to be stretched back and forth, and soot will still get in over time. "

Huang Aihua paused, and then said: "Furthermore, the engineers of Sakurada Co., Ltd. also said that the protective sleeve can only protect the hydraulic cylinder components to a limited extent, but the contaminants will eventually enter the hydraulic oil tank, causing the paint in the tank to fall off and block. The suction filter of the hydraulic pump. On this point, our engineers have also tested it, and it is true."

   "Ha ha ha..." Li Weidong laughed after hearing this.

   "Hey! Teacher Li, what are you laughing at? You think I'm not right? But our own engineers, we can't make a mistake!" Huang Aihua said dissatisfied.

   "Director Huang, you were scammed by Sakurada Co., Ltd.!" Li Weidong said.
