Hearing Feng Xiaochen's mouth said the word "trapped oil", Yu Chun'an completely understood: this small director's stomach is real, perhaps Linbei heavy machine this time is a blindfold, that Peng ocean is just a guise, the real ability, is this silly young director.

Hydraulic parts are dependent on the liquid to transmit pressure, hydraulic oil in the action of external force intermittently from the low pressure area to the high pressure area is pressed to the high pressure area, or from the high pressure area to the low pressure area, there will be an instantaneous pressure change, this phenomenon is called trapped oil.The reason for this name is estimated that in this process, the hydraulic oil is controlled in a closed cavity, like a trapped beast.

The trapped oil causes the liquid to flow, thereby increasing the temperature of the liquid, and at the same time, some whistling sounds.In daily life, we occasionally hear the squeaking of the water pipes at home, which is the result of the phenomenon of trapped oil, which is caused by the sudden change of water pressure in the water pipe.

The problem of noise generated by trapped oil is common sense for future hydraulic technicians.But in that year, because the noise problem was not taken seriously, many technicians did not know this point, or did not study the problem in depth.

Just before Feng Xiaochen did not come, Yu Chun'an and several workers also talked about the problem of trapped oil, and everyone vaguely felt that the appearance of noise and trapped oil may have some relationship.But specifically in which part of the occurrence of trapped oil, how much impact, we still can not eat.In addition, whether there are other factors that cause noise, which is also the topic of discussion, and everyone has some quarrels.

Feng Xiaochen once presided over the localization of hydraulic parts, worked with many top technicians for a period of time, and also saw them dissected many kinds of hydraulic parts, and evaluated various hydraulic parts.Yu Chun'an is pondering this axial piston hydraulic pump, is a traditional product, in the field of machinery is very widely used, so Feng Xiaochen has also been exposed.As early as Yu Chun'an raised the noise problem, Feng Xiaochen has already remembered the conclusion of future generations, that is, the main source of noise of this plunger pump is the phenomenon of trapped oil caused by improper design of the oil plate.

At first, he did not say what he knew, but wanted to explore the bottom of Yu Chun'an and others.As a result, Yu Chun'an and others did not open their mouths, but came out a Han Jiangyue and shouted with him, laughing at him for not understanding technology.Feng Xiaochen also no longer pretended to be low-key, he decided to use strength to win respect for himself.

"Yes, it's the director of the big factory."He Guihua raised a big thumb and praised Feng Xiaochen.Feng Xiaochen can say the word trapped oil, it proves his strength, you know, the new private plant technical department of the technicians are not anyone can say these two words.

“Failure, right?”Han Jiang Yue half-believed that she really did not believe that Feng Xiaochen could know what was the troublesome oil, at least she had not heard of the matter of trapped oil before today, or whether she had just heard Yu Chun'an talk about this when everyone analyzed the hydraulic pump together.She turned to look at Yu Chun'an and said, "Yu chief, is this what you told him?"

Yu Chun'an waved: "No, I never told Director Feng about the hydraulic pump, it is Feng's director is well-informed, it is clear at a glance."

"I don't believe it."Han Jiang Yue said with a hard scalp, "Surely he heard it from somewhere."

"Of course I heard it from somewhere else."Feng Zhichen said, "I am not an inventor, how can I invent a new word."

“Even if you know...”

Han Jiangyue was trying to arrange another reason to disparage Feng Xiaochen, Yu Shuan interrupted her words and said to Feng Xiaochen: "Feng Director, you just said that the symmetrical oil distribution plate will produce trapped oil, what is the non-symmetric oil distribution, how can it solve the problem of trapped oil?"

Feng Xiaochen said: "The emergence of noise is due to the torrent caused by trapped oil.The solution to the problem is to design a discharge structure in the trapped oil area, which can make the pressure transition of the internal oil cavity as smooth as possible.Everyone come to see . . .

At this point, he pulled a drawing on the workbench, picked up the pencil on the drawing, and drew a diagram for everyone:

"We designed a pre-pressure tank in the exit position, so that the hydraulic oil is compressed in advance, rather than being pressed to the extreme all at once.Similarly, in the import position, a pre-swollen tank is designed to release the pressure of the hydraulic oil in advance.In this way, the pressure and release process is elongated, there will be no instantaneous oil pressure changes, so there will be no torrent noise."

“Wonderful!”Ye Jiansheng patted his thighs, "This way, the whole oil pump structure does not need to be changed, is to change the oil tray, it is very easy."

"It's really good, you only need to open two slopes on the oil plate, one by one."Why didn’t I think of it!”Yu Chun'an was happy and chagrined, he also thought of the problem of trapped oil before, has been in the oil plate oil and oil control on the oil control, did not think of the design of the unloading tank idea.At this time, Feng Xiaochen said that he suddenly realized that there was such a simple solution to this problem.

“The Lord, what he said, is it really useful?”Han Jiang Yue La Yushun'an's horn of clothing, asked in a low voice, although she is a very smart young worker, but the principle of hydraulic pump is far less familiar than Yu Chun'an and several masters, so I can't hear Feng Xiaochen's opinion for a while.She saw that Ye Jiansheng and Yu Chun'an were even claiming wonderful, and couldn't help but beware, did this horrendous little director really put forward a wonderful plan?

“ totally useful!”Yu Chun'an said with certainty, "The idea of opening and unloading the slot, I have also seen it in the past, but I can't contact it when it is used."The director of Feng is really high-level, and he can think of such a good way."

“Hm!”Han Jiang Yue grunted again, and then looked at Feng Xiaochen's eyes, it was somewhat complicated.

He Guihua looked at the drawings, picked up the oil tray and looked at it, nodded and said, “I also think it is effective, Yu Chief, or let’s try it first?”

“Yes, try it.”Yu Chun'ando, he rubbed his hands excitedly, his face was full of excitement, not at all, who owed him money when Feng Xiaochen saw him in the morning.It seems that this man is also a man of temperament, but he did not meet the people worthy of his dealings, he became a stuffy gourd.

"Thankson Feng, look at this pre-press angle, how much is appropriate to open."Allah asked in the voice of the Qur’an.

Feng Xiaochen shook his head: "I am not professional, I just said that, but also from the information, specific to the calculation, I will not work."

"Professor Feng is very humble, if you do not work, then no one in our whole new civil factory dares to say their own spirit."Ye Jiansheng said in a flattering tone next to him.Previously, a few of them were also very kind to Feng Xiaochen, but only because Feng Xiaochen was the director of the factory, they had to give a face.And now, Ye Jiansheng's attitude is entirely sincere, which is the respect that Feng Xiaochen earned with his own ability.

Yu Chun'an did not force Feng Xiaochen, he was a professional in mechanical origin, know that such calculations like this kind can not be done casually, Feng Xiaochen said that he is not clear, it may be the truth.He touched his forehead for a while, wrote a few parameters on the drawings, and then handed to He Guihua, "Master He, you first change a oil tray at this angle to try, if there is an effect, I will do some more accurate calculations."

“Good, hey!”He Guihua promised, took the drawings and went outside, and Han Jiangyue hurriedly ran over.It takes a milling machine to slot on the oil tray, and they went to the metalworking workshop.Pliers are a very comprehensive type of work, many fitters can operate the machine tool, sometimes some parts are flawed, need to work back to the machine tool a little, some fitter is their own.

In the morning, Feng Xiaochen saw Han Jiang Yue milling machine in the workshop, it is not a strange thing, He Guihua's milling machine operation and lathe operation is more skilled than Han Jiangyue, even in front of the milling and car workers in the metalworking workshop, his technology can also be ranked.

Processing and matching oil plate takes some time, Yu Chun'an sent Ye Jiansheng and Zou Sulin to work first, and accompanied Feng Xiaochen to the outside of the workshop.After standing under the tree, Yu Chun'an took the initiative to pull out his cigarette and handed a hand to Feng Xiaochen.

“Thanks.”Feng Xiaochen took the cigarette, took a lighter out of his pocket, first helped Yu Chun'an to light the cigarette, and then gave himself a point.In the future, Feng Xiaochen did not smoke, and the smoking habits of this life were inherited from the possessed Feng Xiaochen.In normal times, he does not smoke himself, but when he encounters with people, he can cope with one or two.In those days, the focus was on tobacco and alcohol, especially in the factory, and if you didn’t smoke, your relationship with the workers would even be a little distant.

"Yu section chief, do you modify the design of the hydraulic pump in this way, and do not need to pass the approval of the technical department?"Feng Xiaochen asked curiously.

Yu Chun'an spat out his cigarette and said mockingly, "Wait for them to approve, then nothing can be done."

“Say this at first?”Feng Xiaochen.

Yu Chun'an said, “Feng Director...”

"The mayor still calls me Xiao Feng."Feng Xiaochen interrupted Yu Chun'an's words and said.In the morning, he asked for it, but he refused mercilessly.Now he wants to try again, to see if the hand technology that has just been exposed can eliminate the rest of the mustard for him.

Yu Chun An paused for a moment, then laughed and said, “Well, then I’ll call you Xiao Feng.”Don't take a bite of the rest of the chief, call me old me."

“All right, old man!”Feng Xiaochen shouted without hesitation, Yu Chun'an's statement, obviously regarded him as his own person, which is Feng Xiaochen's wishful thing.
