Che Wencao didn't understand what Li Xiang meant, and asked, "What are you pointing at the engine?" Didn't I say it earlier? It's a problem with the body, and you only point it out now, and it's inevitable that you will be assessed! ”

Li Xiang was quite speechless, he clearly pointed to the oil cooling filtration module, shook his head, and said, "I also said just now, it's not the problem of the body, it's the problem here." Pen, fun, pavilion www. biquge。 info”

Li Xiang directly clicked on the oil cooling and filtration module.

However, Che Wencao was still at a loss, and subconsciously asked: "What is this, how can it be related to this quality accident?" ”

As soon as Che Wencao's words came out, it caused an uproar among the people around him, who couldn't imagine that the quality engineer sent by the quality department didn't even know the oil cooling filtration module.

"Isn't he, really from the Quality Department? I don't even know this, cut! ”

"What do you know? Originally, I suspected that he was not from the quality department, but now I am sure that those people who can only be in the department only know that they drink tea and read the newspaper in the office, and they will definitely not recognize the parts on the engine, haha! ”

"The level of this surnamed Che is too inferior, so I still want to assess our Director Li, and our Director Li's ability to dump him for several streets!"

"Shhh, be quiet, maybe it's because this surnamed Che is jealous of our Director Li's talent that he deliberately framed him."

Che Wencao regretted it when he just said that, and at this moment, he heard the people around him talking, and he was not in a hurry to be embarrassed, but fortunately, his face was thick enough, and he still kept his face unchanged.

Zheng Bingshen, the inspection squad leader of the test run, knew Che Wencao before, after all, he was in charge of quality, and he usually dealt with him, and at this moment he saw Che Wencao's embarrassment, and couldn't help but relieve him and said: "Lathe, Li Xiang means that the cause of the fault is on this oil cooling filtration module." ”

"Impossible!" Che Wencao said categorically.

When Zheng Bingshen said this thing, Che Wencao breathed a sigh of relief, he knew that this thing called the oil cooling filtration module, although he had not seen it before, but he had also seen some information about this thing.

Mu Zhongyue smiled and said, "The lathe worker said that it is impossible, is there any basis?" ”

Che Wencao glanced at Mu Zhongyue, and said as a matter of course: "Don't you know that this oil cooling filter module was purchased by the Expo Company?" Expo is a world-renowned auto parts supplier, how can there be a problem with their products? ”

Che Wencao thought that his reasons were sufficient, but the eyes of the people around him looked at him like fools, full of ridicule.

Mu Zhongyue was also stunned by Che Wencao's answer, and said softly: "Lathe worker, this can't be counted as a reason why they don't have problems, right?" ”

Che Wencao also reacted, his evidence was not sufficient, snorted lightly, and stopped talking.

Mu Zhongyue shook his head, turned to Li Xiang, and asked, "Director Li, you mean that there is a problem with this oil cooling and filtration module, so what is your basis?" ”

Li Xiang nodded towards Mu Zhongyue and replied, "I came to a conclusion by analyzing the working principle of the oil cooling filtration module. ”

Looking at everyone's hopeful eyes, Li Xiang continued: "We know that when the pressure difference between the main oil duct and the auxiliary oil duct is greater than the opening pressure of the bypass valve, the bypass valve is opened, and the oil will enter the auxiliary oil duct to provide lubrication for related parts. ”

Zheng Bingshen, who was listening from the sidelines, didn't expect Li Xiang to suddenly ask himself, and hurriedly said, "Director Li, what you said is very right. ”

Li Xiang smiled slightly and said: "Therefore, if the bypass valve works abnormally, then it will cause the oil pressure of the main oil duct to rise and the parts to be lubricated poorly, which coincides with the failure of this test run, so I judge that the main reason for this quality accident is that the bypass valve is stuck or stuck." ”

Che Wencao pursed his mouth and said disdainfully: "This is just pure speculation of yours, and you can't prove it!" ”

"Damn, isn't it, this Che Wencao is so shameless, Director Li has analyzed the problem so clearly, and he is still quibbling there."

"There's no way, who makes the family the quality department."

Mu Zhongyue glanced at Che Wencao with dissatisfaction and said, "Director Li's analysis is reasonable and well-founded, I personally agree with it, and what other people think." ”

Li Xiang took a step forward and said: "Director Mu, what the lathe worker just said is not unreasonable, I really only rely on its working principle analysis, can not be used as a basis, I suggest that this oil cold defiltration module be cut apart to see the situation inside."

Mu Zhongyue nodded, agreed to Li Xiang's proposal, and arranged for relevant personnel to wire cut the oil cooling filtration module.

The work personally arranged by the director of the technical quality department was still very efficient, and after a while, two dissected oil cooling and filtration modules were taken.

Under the leadership of Mu Zhongyue, everyone immediately surrounded them, and several inspectors stood in front and observed carefully.

"There is no obvious rust in the valve core, and there is no foreign matter in the valve hole."

"Traces of anomalous contact were found at the bottom of the valve hole."

"It was very laborious to manually open the bypass valve before the dissection, but now the spool can be removed with a little force, indicating that the spool is not stuck due to adhesion, but is related to the size of the local fit."

Several inspectors quickly told their inspection results, and Li Xiang listened to them and nodded slightly, which was consistent with what he had just observed with the Divine Eye.

"What does that mean?" Che Wencao asked.

Li Xiang turned around and said, "This shows that the processing size of the valve core or valve hole is unqualified. ”

In fact, these were not originally speculated by Li Xiang, but directly seen with the eyes of God, but they had to justify themselves, so they talked so much, otherwise no one would believe it if they directly said that they saw it.

"Impossible!" This time it was Zheng Bingshen who spoke, "At that time, the production schedule of the second-generation aircraft was not much, and as the oil cooling and filtration module specially equipped with the second-generation aircraft, we were 100% tested, and there was absolutely no unqualified phenomenon." ”

Li Xiang frowned, he didn't look at Zheng Bingshen's appearance like nonsense, but he did see through the divine eye that the size of the valve hole was unqualified, and this would not be wrong.

"He's just talking nonsense!" Che Wencao quarreled again.

Li Xiang snorted coldly, began to dislike this quality engineer, and said, "Then how about bothering Team Leader Zheng to measure one piece on site?" ”

Without waiting for Zheng Bingshen to answer, Mu Zhongyue had already asked someone to bring a new oil cooling defiltration module, which was the same batch as the one dissected before.

Zheng Bingshen was very dissatisfied with Mu Zhongyue's behavior, but the other party was the leader, so he couldn't say anything, so he could only obediently pick up the tool to measure.

"You guys, the diameter of the valve hole is 16.05mm, and the size requirements are 16+0.05mm to 16+0.12mm, which is qualified!" Zheng Bingshen said, let the dial of the inner diameter dial gauge out for everyone to see.

Li Xiang frowned, lifted his divine eyes, and looked into the valve hole along the stem of the inner dial gauge, and after looking at it for a while, the corners of his mouth raised slightly, and he said in his heart, I see!
