071 Tiny Hydraulic Hose

"Xiao Xie, this is Liang Xiaolong, the workshop director of the test workshop, you don't have to go every day, he reports to you in detail every day about the situation in the workshop, and if you have any task arrangements, just go through him directly. Zheng Yucheng waited at Xie Kai's house with a young man in his thirties.

Liang Xiaolong looked at Xie Kai with a surprised expression.

Originally, he thought that Xie Jianguo was the behind-the-scenes controller of their workshop, but he didn't expect that it was actually a child.

Zheng Yucheng made it clear to him that he must be conscientiously implemented according to the requirements.

Even if he was surprised, Liang Xiaolong, who knew the importance of that workshop, did not show it on his face.

"Comrade Xie Kai, if you have any direct orders in the future, you have the final say on how to do the workshop. At the same time that Liang Xiaolong looked at Xie Kai, Xie Kai was also looking at him.

Liang Xiaolong's reaction surprised Xie Kai in his heart, it was not easy for a person in his thirties to work under the command of a child in his teens.

He didn't care too much, and nodded, "It's hard work Director Liang." ”

"In the future, the drawing will also be handed over to the technician in the workshop, you draw the sketch, they will improve, what do you think?" Zheng Yucheng asked Xie Kai.

"That's the best, for now we have to let them know about the tank structure and the project. Director Zheng, about the engine, did you communicate there?"

"Shipped from 617, already on the way. The latest improved model, 730 horsepower, should be enough, right? Now Cheng Ping and they have begun to build composite armor models and test materials, and you can start to act in this workshop. Zheng Yucheng said, "For other things that are needed, such as low-light night vision devices, etc., I have contacted Yunguang 298 Factory, but there is no specific reply." ”

"What about the technology they don't have?" Xie Kai asked, "especially the laser sight, etc., which are not existing technologies." ”

"Let's figure it out. If it really doesn't work, just replace it with something else and wait. It's useless to be in a hurry. "Zheng Yucheng can't help it, if he has enough money, he will do it himself. "By the way, the military will send people over in a few days to observe the power of electromagnetic bombs and cloud burst bombs. ”

"Did the military give a reply?" Xie Kai became interested.

Someone has to ask for something, otherwise the project research and development funds will be smashed in it.

"Yes. We now belong to the military logistics management. Both weapons are of interest to the military. Zheng Yucheng said, "If you pass, you will make a great contribution." ”

Liang Xiaolong listened curiously on the side, he knew too little about Xie Kai, and Zheng Yucheng did not introduce him to him, only introduced Xie Jianguo, the new chief engineer of Hongqi Machinery Factory.

"You might as well be practical. Director Zheng, should I return the money from the school to my mother?

The verbal check is useless, the financial situation of the base has improved, and Xie Kai doesn't know how much money was given on it, at least it is tens of millions.

"What are you anxious about, will you be in a hurry? If you lend it to the school, you have to ask Deng Huakang for it! It was he who typed the note, and the school's salary, and he also asked people to get it back from the finance department......" Zheng Yucheng looked at Xie Kai's face and felt a secret refreshment. "Besides, isn't the house also given? Now start saving money, and when it's time for you to marry a daughter-in-law, you will definitely not be short of money. ”

Xie Kai was so angry that he almost vomited blood.

Let him ask Deng Huakang for money?

It's a joke.

Xie Kai had a feeling that he would not return the eighteen thousand dollars he had lent to the school for his salary.

At least now, he doesn't dare to mention it, otherwise Deng Huakang will personally catch his attendance every day.

"Okay, you communicate with Xiao Liang first, I still have something to do, so I'll leave first......" Seeing Xie Kai's face change, Zheng Yucheng immediately said goodbye and walked away.

Xie Kai looked at his back and cursed secretly.

The old guy didn't have a good idea in the first place.

"Director Liang, in the workshop, let's dismantle the turret of 59 first, familiarize yourself with the layout, etc. The new assembly drawings are in the Armored Technology Research Institute, you go to Chief Engineer Zhang Deming, and the technicians in the workshop will first understand and improve the drawings...... Let the carpenter build the model according to the drawings first. Seeing that Liang Xiaolong was still here, Xie Kai took more than a dozen drawings from his room and said at the same time. "The data on this has not yet been marked, and we will discuss and determine the data according to the size of the 59 tank. ”

Liang Xiaolong took the drawing, nodded, and didn't communicate too much.

Xie Kai was much younger than him, so he obeyed Xie Kai's orders, and he felt awkward in his heart.

What's more, it's late at night, and it's not good to stay at someone's house.

"Dad, what's wrong with your excavator project?" When Xie Jianguo came back, it was already past 12 o'clock, and seeing his father staggering and haggard, Xie Kai felt a faint pain in his heart.

Xie Jianguo frowned and looked at his son, "Why haven't you slept yet?"

"Director Zheng just left, and my mother hasn't come back from overtime. Xie Kai said, "He came here to ask about the excavator project, and said that the military would come to the army." ”

"Alas, I was oversimplifying. In a short period of time, it is difficult to figure it out within three months without solving the problem. Xie Jianguo sighed.

"What's wrong?" Xie Kai believes that with the technical strength of Hongqi Machinery Factory and excavator technology, there should not be much difficulty.

Although there is no experience to follow, the engine currently on the market is not as powerful as the 59 tank.

The key hydraulic system, the technical strength of Hongqi Machinery Factory will not be too difficult to solve.

"The hydraulic system has been designed, but the hydraulic pipes that can be found in China cannot withstand the changing pressure...... "Xie Jianguo is under tremendous pressure, and in the factory, the pressure must be hidden, otherwise it will affect everyone's mood."

At home, it can be much easier to talk to your son.

"Hydraulic pipes, not the hydraulic pump?" Xie Kai looked surprised.

A small hydraulic hose can put the whole project in jeopardy?

"The hydraulic pump is fine, but the hydraulic pipe is not strong enough. Excavators need a lot of hydraulic pressure in their work, and they can't arrange too many hydraulic pipe......s," Xie Jianguo explained.

Xie Kai knows that the working parts of the excavator mainly rely on the hydraulic pipe to transport hydraulic oil to generate pressure and control the action of each joint.

Once the hydraulic pressure is insufficient, the excavator will be limp.

"Separate the hydraulic lines in each part. ”

"You think we don't know? The pressure is not enough, the existing pipeline cannot withstand it, and if the oil pressure is too high, the pipeline will burst, causing a hydraulic leak. Xie Jianguo felt like a drowning man, holding on tightly to a straw when he encountered it.

My son is only 16 years old, and no matter what, I don't necessarily know what's going on.

Xie Kai was dumbfounded.

In the past, they engaged in technology, and the domestic industrial system supporting has been improved, except for materials or parts with special requirements, they can be found directly.

If you can't find it, you can also find relevant research units to develop.

Hydraulic pipes are completely out of their tangled range.

Who would have thought that in the early eighties, something as common as hydraulic pipes, which was simply inconspicuous, would stop the entire excavator project?

"No, Dad, in the sixties, Jiangnan Shipyard made a 10,000-ton hydraulic press, and their hydraulic pipes can withstand greater strength than excavators, right?" Xie Kai really has no way, "There are a lot of domestic excavator manufacturers." ”

"The Jiangnan plant uses stainless steel pipes, which are hard pipes. The joints of the excavator need to be connected with hoses...... Most of the domestic excavators are small and backward in technology, otherwise they would not think about introducing technology. Xie Jianguo grabbed his hair and said distressedly.

Before the experiment, they all thought it was easy.

When the design was verified and verified, it was found that the domestic hydraulic pipe could not withstand the huge pressure and was easy to burst.

"So, you can only solve it by making your own hydraulic hose?" Xie Kai asked.

Xie Jianguo nodded, "The pipeline workshop in the factory has been busy for this, several all-nighters, but the technical force over there ......."

Xie Kai kept thinking about what kind of hydraulic hoses they were using.

He knows what the material is, and he also knows that the hydraulic pipe is divided into an inner rubber layer, a middle rubber layer and an outer rubber layer, and each layer has a thin steel wire as the skeleton layer.

The inner rubber layer protects the steel wire from erosion, and the outer rubber layer protects the steel wire from damage.

It stands to reason that the same should be true for the current domestically produced hydraulic pipes.

"How many layers of steel wire do we have in our hydraulic pipes?" Xie Kai asked.

"Four floors. Xie Jianguo, who was worried, looked at Xie Kai and replied suspiciously.

"Why don't you add more steel wire layers? The steel wire layer is woven into a mesh with stainless steel wire tilted at 45 degrees, each layer is glued, continue to increase the steel wire layer, and then glue, if four layers are not good, use six layers ......," Xie Kai said.

He didn't know about it, anyway, many of the hydraulic hoses they used were made of six layers of stainless steel.

At present, the use of domestic hydraulics is not very much, the most important thing is the large hydraulic press, which is fixed, and the use of stainless steel pipes can be realized.

"As a result, the pipes are too thick and prone to damage during the working process. Xie Jianguo pondered the feasibility of his son's proposal.

"On the boom and small arm of the excavator, the hydraulic pressure is directly delivered with stainless steel pipes, a section of hose is used at the joints, and the hydraulic hose woven with stainless steel wire mesh will also have sufficient strength. The pipe is thicker, as long as it can solve the problem, it will be solved? Xie Kai said.

Whether it would work or not, he didn't know.

The pipe of the hydraulic pipe is indeed very thick, which he knows.

What I can do is to tell my father what I have seen, and let them figure out how to figure it out.

The wall thickness is not a problem, as long as it can meet the requirements and have enough service life.

Later, there are more advanced materials, and then we will consider others.

"Your proposal is good, if it is feasible, I will reward you with 50 yuan!" Xie Jianguo felt that this idea was feasible, and they had considered it a little bit before.

With an excited look of praise to his son, he grabbed his clothes and rushed outside.

"Dad, it's past twelve o'clock, I'll go to work tomorrow!" Xie Kai was a little speechless, and his father turned into a workaholic.
