Four hundred and fifty-four deployment and control
The simulation classroom not only provides him with far more learning time than others, but also simulates various machine failures for him, allowing him to practice again and again until he forms a conditioned reflex.
But it was obvious that Technician Tian knew nothing about this, so he was about to receive a "slap in the face" from Zhang Yu.
Within the next hour, technician Tian stared blankly at Zhang Yu. After checking the production line up and down, he easily got under the machine, unscrewed a few screws, and removed a bearing.
Zhang Yu took the bearing and walked to the side of Factory Director Wang, pointed at the bearing and said: "There is something wrong with the bearing. Either the sealing sleeve and the fixing bolt are loose, or there is a gap in the bearing gland, the sleeve, and impurities.
The lubricating oil entering the bearing box from these gaps becomes dirty, causing poor lubrication and eventually leading to bearing failure.
If the fault lasts for a long time, it will cause the bearing to wear and add tools, so it becomes what it is now."
Having said this, Zhang Yu sighed and looked at the severely worn bearing in front of him. This was not a big problem in the first place. In future generations, just replace a bearing.
But now, it is very difficult. He had already seen during the disassembly process that there is currently no production conditions for this kind of bearing in China.
Therefore, if you want to replace the bearings, you can only rely on the hands of master craftsmen. The most likely place to manufacture such bearings is the Hongxing Steel Rolling Mill.
And after overhauling so many machines, Zhang Yu also discovered a problem that exists in many domestic factories, that is, these technicians have no concept of regular maintenance of machines.
Usually when a machine breaks down and the machine is being repaired, things like lubricating oil will be replaced.
So over time, those machines will always have some small problems, and if these small problems accumulate too much, they will cause excessive wear of some parts of the machine, affecting the operation of the machine.
Looking at the bearing in Zhang Yu's hand, technician Tian slapped his brain hard. Why didn't he think of checking whether there was any problem with the bearing?
Not only did he not expect this problem, but Lao Ma also didn't expect that the two old technicians could not keep up with a little kid in repairing machines. How could he accept this fact?
Seeing the disbelief on Technician Tian's face, the factory director's secretary smiled and said that you should not underestimate him. Although Master Zhang is young, he is very capable.
But now is not the time to worry about this. The most important thing for them now is to repair this production line.
Zhang Yu has taken action to find the problem, and then the next thing will be easily solved.
Because Master Xu was still in the hospital, and Director Wang was worried about others taking action, the task of going to the Red Star Rolling Mill to seek support fell back into Zhang Yu's hands. After all, whether he admits it or not, Zhang Yu is Red Star in everyone's eyes.
People who come from the steel rolling mill have some respect in the Red Star Steel Rolling Mill, so it should be easier than them to go to ask for help.
Due to time constraints and in order not to affect tomorrow's production, Zhang Yu and Director Wang didn't even have time to take a breath, so they took the car back to the Hongxing Steel Rolling Plant.
By the time they returned to the Red Star Steel Rolling Mill, it was already dark and most of the workers had already left work.
After learning of their purpose, Factory Manager Yang temporarily asked some masters to hire some masters, asking them to work extra night shifts.
For this kind of thing, the old masters of Hongxing Steel Rolling Mill have become accustomed to it. As one of the few eighth-level fitters, they often have to deal with requests for help from the factories below. Therefore, after learning their purpose, the old masters
We discussed it for a while first, and then returned to our workstations to do our own work according to the division of labor.
While Zhang Yu and Factory Director Wang were anxiously waiting for the results of the old masters, Zhao Wenzhuo finally got off work. He looked at the contents of the letter left by Zhang Yu, and the relaxed expression on his face was gradually replaced by seriousness.
, especially after seeing the part that Zhang Yu guessed, he stood up suddenly, picked up the police uniform beside him, and rushed back to the police station without stopping.
After returning to the police station, he quickly summoned all the police officers he could and announced the information he had received from Zhang Yu. Of course, he copied Zhang Yu's role and only used informants instead.
Zhang Yu.
However, as police officers, they have several unknown informants under their command. As for the source of Zhao Wenzhuo's information, they only thought that an informant discovered it and did not pursue the source.
After Zhao Wenzhuo and his party finished the meeting, they launched a control operation at the scrap collection station overnight.
When Zhang Yu was fascinated by Huhu and was about to fall asleep, Zhao Wenzhuo was lying with his men in the room of the scrap collection station, looking at the place Zhang Yu mentioned with burning eyes.
"Bah!" After one of the team members killed another mosquito, he couldn't help but move his body, came close to Zhao Wenzhuo, and asked in a low voice: "Brother Zhao, do you think they will really come tonight?"
"Not sure, but we have provided conditions for those people to come over."
He first asked someone to investigate and made sure that the group was still watching the scrap collection station.
In order to make those people relax their vigilance, and to induce their sense of urgency, they just found the old man who was the gatekeeper and his direct leaders and asked them to perform this scene.
So that they would know that a certain big shot had taken a liking to the scrapyard job in order to arrange jobs for his relatives.
On the grounds that the janitor at the scrap collection station was old and could no longer take care of him, and the scrap collection station needed someone to work the night shift, he placed two young men there. For this reason, he wanted his son to take over his job.
The janitor also had a quarrel with his boss.
In this way, no matter whether those people take action tonight or not, the initiative is in their hands.
If those people act tonight, they can catch them.
If they don't take action, they can also take advantage of this scene and arrange for two unfamiliar policemen to enter the scrap yard to act as the so-called relatives of the leader.
"Oh." The police officer was a little disappointed after hearing what Zhao Wenzhe said, but his attention was quickly attracted by the mosquito.
The area of this scrap collection depot is not small, with several rooms, not to mention a huge yard.
In such a big place, only the janitor works alone. He is not young anymore, so it is naturally impossible for him to clean it every day. In addition, this place is a scrap collection station, and scraps are put in every day. It is inevitable that those things will be
It is a bit dirty, so over time, there will naturally be many sanitary blind spots in the waste collection station, and there will naturally be many mosquitoes inside.
