The requirements of the hydraulic press for the working medium are still very high, if the hydraulic oil leaks, it will inevitably affect its working pressure, so that the mold can not get enough pressure, the molded friction plate, the internal mechanical properties will naturally decline, and the phenomenon of burning is reasonable.

Of course, this is only Zhou Jingming's current speculation, and he is not sure that the burning of the friction plate must be related to the working pressure of the hydraulic press, and the follow-up comparative test is needed to prove it.

But at least for now, there is a clear direction!

"This wave is not a loss!" Although he couldn't take a lunch break, he was able to find a breakthrough point in the problem, which was more important to Zhou Jingming than anything else.

After carefully confirming the oil leakage of the hydraulic press, Zhou Jingming estimated that Lao Huang and Hu Yibing should also get up, so he simply stayed in the workshop, ready to tell them about his findings.

Soon, Lao Huang and Hu Yibing came side by side and walked towards the workshop.

"Just on the way, I told Master Huang where have you been? It turns out that Comrade Xiao Zhou has come here!"

"What, didn't you take a lunch break?" Lao Huang saw the oil stains on Zhou Jingming's hands, and probably understood something in his heart. 's appreciation for Zhou Jingming has become stronger and stronger.

Even if the technology is good, the key is to work so hard, but few young people are willing to give up their lunch break for work.

"Master Huang, Director Hu, come here, I should have found the cause of the problem. Zhou Jingming didn't have time to chat, so he came up and got into the topic.

Since it was a matter of work, Lao Huang and the two did not delay, and hurriedly followed behind Zhou Jingming, Hu Yibing, who was still a little sleepy-eyed just now, was also completely awake at the moment, he was afraid that there would be no way to solve this problem at that time, and then his small factory would really go out of business.

The three of them surrounded a hydraulic press, and Zhou Jingming told him what he had just discovered.

"Comrade Xiao Zhou, do you mean that the working pressure of the hydraulic press is insufficient, so it caused the friction plate to burn?" After listening to Zhou Jingming's words, Hu Yibing couldn't help but breathe a sigh of relief. If it's really just a matter of the working pressure of the hydraulic press, then it's easy to solve.

"It's possible. When molding, the pressure is insufficient, the various materials in the mold are not fully combined with asbestos, the mechanical properties are reduced, and the friction plate is burned. Lao Huang patted his head, and the problem seemed to be solved.

Zhou Jingming looked at Hu Yibing, "Director Hu, the working pressure of the hydraulic press is adjustable." ”

"Yes. There is an oil leak in the hydraulic press, it is true that we are not in place, and I hope that the two of us can give us another chance. Hu Yibing's idea is very simple, that is, no matter what, he must keep his cooperation with SAIC. If it is really the lack of pressure that causes the friction plate to burn out, the problem is indeed theirs.

"Director Hu, it's not time to hold accountable. Since the pressure can be adjusted, can we ask Director Hu to fix the oil leakage problem of these hydraulic presses, and then adjust it to the normal working pressure before production, we need to bring a batch of friction plates produced after pressure adjustment back for comparison with real vehicles. ”

For now, this is just a speculation by Zhou Jingming. However, regardless of whether the working pressure is not enough, whether it is the main reason for the burning of friction plates, there are still many places in the management work of such a workshop-style factory, which should also be paid attention to.

Normally, the equipment should have a regular maintenance cycle, but it is obvious that Hu Yibing does not know about the oil leakage of the hydraulic press, which is definitely a loophole in management.

"Of course, I immediately shut them down for maintenance, and soon they were able to produce at normal pressure. ”

Under Hu Yibing's arrangement, more than a dozen people in the workshop immediately stopped their work and began to be busy repairing the hydraulic press, and the pressure detection showed that the working pressure of the hydraulic press was indeed smaller than the pressure required by the friction plate, which strengthened Zhou Jingming's guess.

It took more than an hour for all four hydraulic presses to be repaired and the production line started again.

After getting the newly produced friction plate, Zhou Jingming and Lao Huang refused Hu Yibing's proposal to spend the night here, and hurriedly rushed back by car, and they wanted to report the progress of the matter to Zhao Ke as soon as possible.

Office of the Director.

The return of Zhou Jingming and Lao Huang made Zhao Ke, who had been thinking about it all day, finally fall from the stone in his heart, especially when he saw the smiles on the faces of the two people, which made Zhao Ke's heart feel stable.

"It seems that you have found out the reason?" After beckoning the two of them to sit down, Zhao Ke hurriedly asked.

"Fortunately, I was not dishonored. However, the specific result will have to wait until after the loading of the car. Zhou Jingming took a sip of water and smiled.

"This time it's thanks to Xiao Zhou, if it weren't for him, I really wouldn't be able to find out what the problem was. Lao Huang said with heartfelt admiration.

"Master Huang has an overreputation, and I am only doing my best. ”

Zhao Ke remembered the matter of the friction plate in his heart, "Okay, okay, you two will break it, tell me what the specific situation is." ”

Seeing that Zhao Ke was so anxious, Lao Huang and Zhou Jingming looked at each other and smiled, and then Zhou Jingming told Zhao Ke about what happened.

Zhao Ke suddenly said, "It turned out that there was a problem with the hydraulic press." Then the next step is to load the friction plate brought back for verification?"

"Yes. After loading, run for a while to see, if there is no burning, it means that we have found the right reason, and let them produce friction plates according to the current pressure in the future. Zhou Jingming nodded.

"Okay! I'll arrange for someone to try it on tomorrow. Zhao Ke looked at his watch, "You haven't eaten yet, have you?" Let's go, take you down to the restaurant, I'll have a treat today!"

After returning to the dormitory, He Yingxun, who was about to work the night shift, was lying on the bed listening to the tape recorder, and his voice was turned on to the maximum.

"Haven't left yet?" Zhou Jingming suddenly collapsed on the bed and asked weakly.

He Yingxun was just about to answer, when he heard a steady breathing sound from Zhou Jingming's side, "This kid is a pig, he slept so early?"

He Yingxun muttered quietly, lowered the sound of the tape recorder, and finally turned it off altogether.

After running for a day, getting up so early in the morning, and not having a lunch break at noon, Zhou Jingming was really tired.

"Except for my father, I haven't fucking served anyone else!You kid is really good!" Da Xun took off Zhou Jingming's shoes and covered him with a blanket by the way, covering his nose, "It's smellier than Lao Tzu's feet, grass!"

After all this, Daxun just walked out of the dormitory to go to work, but the group of people in the dormitory next door turned the sound of the tape recorder to the loudest.

He Yingxun looked at Zhou Jingming, who was sleeping in the room, and then kicked open the door of the dormitory next door, "It's all fucking organized!

A few people in the room were startled, "Brother Xun, what's wrong? Aren't you going to work, what's in your way?"

"It's in the way of Lao Tzu going to work! let you turn it off, what the are you talking about?" Da Xun's eyes widened, like a husband who was very protective of his little daughter-in-law.
