In fact, as far as Leng Bingguo himself is concerned, he is not very interested in Feng Xiaochen. He did not see the scene where Feng Xiaochen and Meng Fanze were talking, so it was naturally hard to imagine why Meng Fanze valued this young man. However, since Meng Fanze recommended Feng Xiaochen to him, he could not refuse. For this reason, as early as last night, he had already thought of a way to settle Feng Xiaochen.

Hearing Feng Xiaochen's question, Leng Bingguo made a gesture to Wu Ximin. Wu Ximin got up knowingly and left the house. After a while, he came back with an iron lump. He put the iron lump into the middle of the room, then nodded to Leng Bingguo, and then sat back to his seat.

"Xiao Feng, come and see what kind of fun this is." Leng Bingguo pointed at the iron lump and said to Feng Xiaochen.

Feng Xiaochen glanced and replied, "Is this a hydraulic valve?"

"Yeah, it's not bad." Leng Bian Guo praised lightly. Hydraulic valves are devices used in hydraulic systems to regulate liquid flow, pressure, and direction, and are very common in mechanical engineering. It is not a great skill to recognize hydraulic valves. However, if Feng Xiaochen can't even recognize hydraulic valves, Leng Bian Guo doesn't need to say anything further. Just send him to the factory office to help with the complete documents.

"Look at this hydraulic valve carefully to see if there is anything wrong with it." Leng Bingguo continued.

Meng Fanze and Chang Genlin sat next to each other, not interrupting, obviously they wanted to try Feng Xiaochen's weight. Feng Xiaochen got up and walked to the hydraulic valve, squatted down, fiddled with it for a few times, and then said, "It must be that oil leaks, right?"

"Haha, I really have two tricks, and I can see a problem at a glance." Leng Biaoguo's attitude was much more relaxed. The main structure of the hydraulic valve is a valve body and a valve stem. The valve stem is inserted into the valve hole and can be reciprocated under the action of external force to complete the control of the hydraulic oil. In order to ensure the smooth movement of the valve stem, there will be some lubricating oil between the valve stem and the valve hole, and there will be hydraulic oil in the valve body. Feng Xiaochen could see that the oil seeping out of the valve stem is hydraulic oil, not lubricating oil, which is a bit resistant.

Chang Genlin interrupted, "Xiao Feng, since you can tell that it is oil leakage, can you tell what is the reason for its oil leakage?"

"The valve stem is worn, and there are some obvious scratches on it. The hydraulic oil seeps out through these scratches." Feng Xiaochen raised the hydraulic valve, pulled out the stem, and pointed it to Chang Genlin and others.

"So, how do scratches appear?" Chang Genlin continued to ask.

Feng Xiaochen looked at the hydraulic valve in his hand again and said, "The valve hole has a processing defect. If I guess correctly, it should be that sand pressing occurs during the grinding of the valve hole. After the grinding is completed, the emery embedded in the valve hole scratches the valve stem."

"Is this what Mr. Feng taught you?" Chang Genlin looked surprised. He could see that the hydraulic valve leaked oil, and he could explain it with experience. He could find scratches on the valve stem, which could be seen with a little eye. However, being able to tell the defects in the process is a manifestation of real understanding. You should know that a large enterprise such as Linbei Heavy Machinery can see this reason at once, but it is impossible to find one.

Linbei Heavy Machinery does not produce hydraulic parts by itself. This hydraulic valve was purchased from a professional supporting enterprise called Xinmin Hydraulic Tool Factory in Mingzhou Province. The hydraulic valve was installed on the excavator. There was no problem at the beginning, but after a while, there was a slight oil seepage. The work of the hydraulic parts is driven by the internal hydraulic oil. If the hydraulic oil leaks, the internal pressure will gradually decrease, and the hydraulic parts will be difficult to be accurate, which will affect the performance of the entire equipment.

Linbei Heavy Machinery sent a letter to Xinmin Hydraulic Tool Factory to inform the hydraulic valve of oil leakage. Xinmin Factory simply sent two new hydraulic valves without saying a word, one for replacing the damaged one and the other as spare parts. Facts show that Xinmin Factory's approach is very forward-looking. After working for a period of time, the newly replaced hydraulic valve also experienced the same leakage. Fortunately, there were spare parts, so there were no delays.

A hydraulic threshold is not worth much, but replacing a hydraulic valve is very troublesome, and it will take at least half a day. An excavator has to stop and replace the accessories every once in a while. No customer is happy with this kind of thing. Leng Bingguo came from the excavator's industrial experiment site this time and brought the hydraulic valve he had replaced with him. He had notified a deputy chief engineer named Peng Haiyang in the factory to Beijing, preparing to let him take this hydraulic valve to Mingzhou for a trip, and talk to Xinmin Factory, and no matter what, he had to provide products with longer durable life.

Yesterday, Feng Xiaochen suggested to Meng Fanze that the development conditions for the new excavator are not mature. One of the important reasons is that the supporting system is incomplete and the quality of many accessories is not up to standard. He believes that we should first make efforts to solve the production process problems of these accessories, comprehensively improve the quality, and then consider the development of the new model.

Meng Fanze was moved by Feng Xiaochen's idea. When he went to the hospital to discuss it with Chang Genlin, he thought it was the right path, so he went to Linbei Heavy Machinery's Beijing procurement station to discuss the matter with Leng Bingguo. It happened that Leng Bingguo was worried about the hydraulic valve. When he heard Meng Fanze's statement, he felt that it made some sense. He asked who proposed the idea, and then he knew Feng Xiaochen's name.

Meng Fanze is a talent-loving person. He is highly respected in the entire industrial system because he loves and protects talents. He has discovered and promoted and appointed many cadres through his hands. Now these cadres have become backbone of all walks of life, which in turn has improved Meng Fanze's status. After he talked with Feng Xiaochen, he firmly believed that this young man had a bright future, so he wanted to snatch him from Luo Xiangfei. He suggested to Leng Bingguo to absorb Feng Xiaochen into the industrial experiment of a 12-mile excavator to examine Feng Xiaochen's ability in work. Leng Bingguo was inconvenient to refuse, so he came up with an idea, that is, to let Feng Xiaochen accompany Peng Haiyang to negotiate with Xinmin Hydraulic Tool Factory.

According to Leng Bian Guo's idea, aren't you Feng Xiaochen saying you should do the accessories well? Well, you can help us solve the quality problem of the hydraulic valve. Xinmin Hydraulic Tool Factory cannot produce high-quality hydraulic valves. Is there any good way for you?

Of course, before sending Feng Xiaochen to the Xinmin Factory, Leng Bingguo had to explore his bottom and see how much he was. If Feng Xiaochen didn't even know what the hydraulic valve was, Leng Bingguo would not be able to send him to the Xinmin Factory. The person who lost Feng Xiaochen was a little trouble. If Xinmin Factory felt that Linbei Heavy Machinery did not pay attention to this matter and sent a 250 to negotiate, it would be troublesome.

After Feng Xiaochen saw the issue of oil leakage in the hydraulic valve, Leng Bingguo had decided to accept him. The two questions Chang Genlin asked were not what Leng Bingguo wanted to ask, especially the processing technology issue. Leng Bingguo felt that it was a pit.

The quality of domestic hydraulic parts was generally not up to standard at that time, and oil leakage was a very common thing. There are many reasons for oil leakage in hydraulic parts. It may be that the valve holes and valve stem processing sizes do not match, or that the hydraulic oil and the chemical composition of the seals are not corresponding. In short, it is difficult for people who are not in this industry to say the reason exactly.

Chang Genlin asked Feng Xiaochen, hoping to try the young man’s background. After all, Feng Xiaochen is just a 19-year-old man and has never been in the factory. He has taught some theories based on just a great grandfather. Where can he master the technical details?

He never expected that Feng Xiaochen was simply a scattered oil. It would be difficult to find something that Feng Xiaochen was not very proficient in. How could a mere hydraulic valve oil leak stump this later director of the Strategy Director of the Reinstallation Office?

In later generations, in order to change the situation where hydraulic parts are controlled by others, the Reinstallation Office organized a battle to improve the quality of hydraulic parts, and Feng Xiaochen was the host of this battle. He went to almost all hydraulic parts factories in China at that time, and analyzed problems, developed technology with technicians and workers, and accumulated rich experience. For example, the Xinmin Factory, which produced the hydraulic valve in front of him, had become a joint venture in later generations. Feng Xiaochen had been to many times and had good friendships with many cadres and employees in the factory.

"Lao Leng, what else do you have to say now?"

Meng Fanze saw the answer from Chang Genlin's expression. He was overjoyed. It seemed that Feng Xiaochen's ability was a little stronger than he thought. In the future, his reputation as a wise and sensible pearl was probably even more popular. He turned to look at Leng Bingguo and asked with a smile.

Leng Bingguo pretended to be helpless and said, "I'm convinced, I'm convinced. No wonder Minister Meng can be the leader. I, Xiao Leng, can only run errands in front of Minister Meng. Regarding this ability to know and be eloquent, I can't catch up if I study for another 20 years. Well, I admit that I'm betting and accepting the loss. The deputy director of the production department is Xiao Feng."

"This is really not possible. I have too little experience and cannot convince everyone." Feng Xiaochen quickly refused.

"Director Leng asked you to do it, you can do it." Meng Fanze said, "Director Leng wants to send you to Xinmin Factory to contact us to solve the problem of unstable hydraulic valve quality. If you don't have a specific identity, you won't fart. The deputy director of an enterprise is not a very high position, not to mention that you can only work as a worker, which is considered a temporary appointment."

"Okay, since Minister Meng has said it, I will be disrespectful." Feng Xiaochen responded.

"I'm disrespectful, yes, it's true that I have a family background and speak very artistically." Chang Genlin praised.

"Then let's make a decision. Director Luo asked Minister Meng to go and talk about it, and it was said that Xiao Feng was borrowed by us. I will ask the factory office to give a formal notice as soon as possible for Xiao Feng's appointment. Lao Wu, you arrange a house to be Xiao Feng's dormitory in the capital. Although he wants to go to Mingzhou with Peng Haiyang, he still has to come back in the middle and has to have a fixed dormitory."

Leng Bingguo is worthy of being a factory director and is very skillful in doing things. He can explain everything in a short while.
