60s researcher

"Can you ask Director Qian? I remember that his son has a lot of friends and knows a lot of people." As soon as Xu Yan asked for help, Xu Yan thought of Director Qin.

"That's right, Director Qin. Did you invite him tonight?" Lu Jian also felt that this arrangement was very suitable, but Zhao Lei couldn't have invited him, he had helped them a lot before.

"I told him yesterday that he will come tonight, and I will talk to him about helping out in the evening." Zhao Lei went to see Lu yesterday and saw that they happened to meet Director Qian, so he made an agreement with him in advance .

"That's fine." Lu Jian nodded.

"By the way, I'm going to ask Director Zhang and Director Xu to see if they have time today?" Thinking of the tasks Zhao Lei had arranged for him, Lu Jian was going to find the two factory managers now, lest they have other things later. arrange.

"Hey, good brother, I'll trouble you, you go first, I'll wash your dishes for you." Zhao Lei picked up Lu Jian's lunch box in a doggy manner.

"Okay." Lu Jian didn't refuse, and after greeting the other two people, he went to Director Xu and the others.

Lu Jian first went to Director Xu's office, but there was no one there.Afterwards he went to Zhang's office, but unfortunately there was still no one there.Just when he was about to go back and come back later, he saw Secretary He.

"Secretary He, isn't Director Xu here?" Seeing that he seemed a little anxious, Lu Jian ran all the way.

"Director Xu and Director Zhang are both in the car at the door. They are going to a meeting in the province today. What can you do?" Seeing Secretary Lu Jianhe stop, but still looking anxiously at Factory Xu The direction where the chief office is located.

"Then is director Xu coming back today?" Lu Jian saw his anxiety, and asked what he wanted to know without saying any polite words.

"The meeting will last for two days, and I will be back the day after tomorrow."

"It's okay, you can go to work first." Lu Jian didn't mention the matter of asking Director Xu to go to Zhao Lei's house for dinner, and just stepped out of the way.

"Then I'll go first." Seeing that he was fine, Secretary He hurried to the missing information in Director Xu's office, and Director Xu and the others were still waiting at the door.

Seeing that the invitation failed, Lu could only go back to the laboratory. At this time, Zhao Lei had already gone to the agricultural machinery factory, so he could only talk to him at night.

When Lu Jian returned to the laboratory, he put down other things and concentrated on his own experiments.

"Gong Lu, it's not good. Something happened in Workshop No. [-]." Just as Lu Jian was about to connect a line, a person shouted and ran over at the door.

"What's going on?" Lu saw that the thread in his hand fell off with a flick of his hand. He put down the tweezers and looked at the person running over.

"A grinding machine in Workshop No. [-] had a major failure. The motor of the spindle was burned out, and the guide rail was also broken." The person who came was very anxious, his forehead was covered with sweat.

"How could this be?" Lu Jian immediately ran to Workshop No. [-] after hearing his words. This was the first time this happened.

When Lu saw it, there were already many people around the grinding machine where the accident happened, and Mr. Ye was there to take you to check the damaged place.

"What are you all doing here, except for the person in charge of the machine, everyone else is going to do their own thing." Lu Jian went over to drive away the crowd and walked to the edge of the grinder.

"Are you the operator of this grinding machine? There were no casualties in this accident, right?" Lu Jian could smell a strong burning smell as soon as he approached, but the fire had been brought under control.But the condition of the whole machine tool didn't look very good, so he hurriedly asked the worker in charge of the machine tool.

"No, no, if there is a problem, we will cut off the insulation and power according to the operation in the safety manual, then stay away from here, and find a technician." The few people in charge of this grinding machine seem to be still in shock. The one who talked to Lu Jian His hands and feet were trembling slightly, and he was so nervous.

"What was the situation when the accident happened?" Ye Gong was dismantling the machine tool with several researchers, and Lu Jian could only ask about the situation by himself.

"then……"

"Gong Lu, I'm here. How's the situation?" Before the man could speak, Director Qian ran towards him, panting and asking about the situation while running.

"Fortunately, there were no casualties. I was asking about the situation at that time." Lu Jian helped him aside, and then continued to ask that person.

"Go ahead and talk."

The man glanced at Director Qian and continued.

"It was noon, and we started preparing the materials needed for the grinder in the afternoon at one o'clock, and started the machine at 01:30. As a result, the grinder smelled of burning within 2 minutes, and even the guide rail was broken. We really It’s from An’s operation manual, and everyone checked it out before leaving in the morning, and it’s really not our reason.” Speaking of which, the operator of the grinder became anxious and kept shaking his head and waving his hands.

"Yes, it really has nothing to do with us. I don't know why something went wrong all of a sudden."

"That's it."

"..." The young men who were in charge of the machine tool with him also started talking, their faces full of anxiety and tension.A machine tool is expensive, and they can't afford it.It's a small thing to lose your job, but what if you get caught.

"Okay, we will find out the problem, you guys go to the side and wait." Knowing that there is nothing to ask, Lu Jian no longer entangled with him.

"Come with me first." Seeing that Lu Jian had finished asking, Director Qian took those people aside.

Ye Gong and the others dismantled the motor under the main shaft. Thinking that they said the guide rail was also broken, Lu Jian went to the guide rail to check it carefully.

This time the guide rail had a big break, it didn’t seem to be a problem with the machine itself, but it seemed to be caused by thinking. Lu Jian carefully checked around the guide rail, and finally found a two centimeter long piece not far from the break. Iron sheets.

"Director Qian, come and take a look." Lu Jian called out to Director Qian who was still talking to the workers over there.

"What's wrong?" Hearing his voice, Director Qian trotted over.

"It was found on the guide rail of the machine tool. It should be the reason why the guide rail broke." Lu Jian handed him the iron sheet in his hand. The iron sheet had been twisted and deformed, and obvious signs of extrusion could be seen.

"But how could there be such a thing in the guide rail? This should be a raw material that needs to be processed by a grinding machine." Director Qian took it over and took a closer look to confirm that it was a processed material.

"Is this malfunction caused by human beings?" Seeing that Lu Jian didn't speak, Director Qian already had an answer.

"I'll go check it out." Director Qian took the things in his hand and walked away from the place where we talked just now.If it is caused by humans, then the problem is serious.

"What did you say just now, there is absolutely no problem with the operation, and the machine has been checked, so what is it?" Once there, Director Qian became angry and spread the things in his hand in front of several people.

"This one……"

"Gong Lu found this from the guide rail. Is such a big thing inside, can there be no problems? What did you check? Huh?" Director Qian almost roared out the last word, his face was already angry famous.

"Director Qian, we made sure that we checked that place before we left at noon, and cleaned up the metal debris inside. We made sure that there is no problem. There can't be such a big thing in there." The young man in charge of the grinder was very young. Scared, but still forced to speak out.

"Director Qian, he and I checked the guide rails of the machine tool together, and we're sure there's nothing wrong with it." Another young man also stood up, looking at Director Qian with firmness inside.

Director Qian was silent, and he calmed down.If one person said there was no problem, he would continue to doubt it, but now both of them assured him.

"After you left, did anyone else approach the machine tool?"

"We walked together. There were still many people in the workshop when we left, and the warehouse would come over at noon to replenish raw materials for us."

"In this way, you all ask one by one to see who is the last to leave the workshop and who is the last to come, and then ask if there is anyone else approaching here when you are not here." The matter could not be resolved for a while. Director Qian can only ask them to ask around, someone will always see someone approaching here at noon.

Hearing Director Qian's words, the few people standing there seemed to have found hope, and they were about to ask someone.

"Remember not to interfere with other people's work." Director Qian still reminded them before they left.

After talking with them, Director Qian went back to see Lu Jian and them. At this time, the motor of the main shaft had been dismantled.

"Do you know what caused it?" Director Qian glanced at the burnt motor, his brows were also wrinkled, and he was also very anxious.

"Take it apart and take a look." Lu Jian had already squatted next to Ye Gong, and the two picked up tools to disassemble it.Director Qian saw that he couldn't finish it for a while, so he also went to inquire about the situation.

"This is?" Suddenly Lu Jian saw a mark in a place that hadn't been burned yet.

"What's wrong?" Hearing his voice, Ye Gong looked over.

"Look at this place." Lu Jian turned the motor over and pointed to the bottom part to show him.

"Is this water damage?" Ye Gong hesitated for a while, and asked with some uncertainty.

"It's just water stains, there's nothing wrong with it." Lu Jian nodded, very sure.It's just that there is water damage in this place.

"But why? Even if the machine leaks oil, it won't leak to this place?" Ye Gong scratched his head and couldn't think of the reason why the water got in here. Someone can't deliberately sabotage and pour water here.He remembered that there was a rule in the operation manual not to drink water near the machine tool.

"Check the inside of the machine again." Lu Jian didn't make a judgment immediately, and planned to check the entire grinding machine to eliminate other causes of failure.

"Okay." Ye Gong had no objection, so he and Lu Jian led the people to check all the parts of the machine tool one by one.
