"Xiao Xie, this is Liang Xiaolong, the workshop director of the test workshop. You don't have to go there every day. He will report to you in detail about the workshop every day. If there are any tasks arranged, just go through him directly." Zheng Yucheng led a man in his thirties.

Young people of many years are waiting at Xie Kai's home.

Liang Xiaolong looked at Xie Kai with a surprised look on his face.

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

Zheng Yucheng made it clear to him that he must implement it seriously as required.

Even though 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 further orders, you can just give them direct orders. You have the final say on how the workshop will be run." While Liang Xiaolong was sizing up Xie Kai, Xie Kai was also sizing him up.

Liang Xiaolong's reaction surprised Xie Kai. It is not easy for a man in his thirties to work under the command of a teenager.

He didn't pay much attention and nodded, "Thank you for your hard work, Director Liang."

"In the future, the drawing work will also be left to the technicians in the workshop. You draw the sketch and they will perfect it. What do you think?" Zheng Yucheng asked Xie Kai.

"This is best. We need to let them understand the tank structure and project status first. Director Zheng, have you communicated about the engine?"

"It has been shipped from 617 and is already on the way. The latest improved model, 730 horsepower, should be enough, right? Now Cheng Ping and the others are starting to build composite armor models and test materials. Your workshop can start taking action." Zheng Yucheng said,

"For other things I need, such as low-light night vision devices, etc., I have contacted Yunguang 298 Factory, but there is no specific reply yet."

"What to do with the technology they don't have?" Xie Kai asked, "Especially laser sights, etc., which are not existing technologies."

"Let's find a way. If it doesn't work, just replace it with something else and wait. There's no point in rushing." Zheng Yucheng has no choice. If he has enough money, he will do it himself. "By the way, the military will be here in a few days.

People will be sent over to observe the power of electromagnetic bombs and cloud bombs."

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

Someone has to want what is created, otherwise project R&D funds will be wasted on it.

"Yes. We now belong to the military logistics management. These two weapons are of interest to the military." Zheng Yucheng said, "If it is approved, you will have made a great contribution."

Liang Xiaolong listened curiously. He knew too little about Xie Kai. Zheng Yucheng had not introduced him to him. He only introduced Xie Jianguo, the new chief engineer of Hongqi Machinery Factory.

"You might as well come up with something practical. Director Zheng, is it time to return the school money to my mother? Is there any leftover?" Xie Kai looked unhappy.

Oral checks were useless. The financial situation of the base had improved. Xie Kai didn't know how much money was given to him. It was at least tens of millions.

"Why are you so anxious? Are you going to lose this point? You have to ask Deng Huakang for the loan to the school! It was him who wrote the note and the school's salary was taken back from the Finance Department..." Zheng Yucheng looked at it

Seeing the change in Xie Kai's face, he felt happy in his heart. "Besides, aren't you giving away the house? Start saving money now. When you get to marry a wife, 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?

This is a joke.

Xie Kai felt that the money he had lent to the school for salary would never come back.

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

"Okay, you communicate with Xiaoliang first. I have something else to do, so I'll leave first..." Seeing the change in Xie Kai's face, Zheng Yucheng immediately left and left.

Xie Kai looked at his back and cursed secretly.

This old guy had no good intentions from the beginning.

"Director Liang, in the workshop, let everyone first dismantle the 59 turret and familiarize themselves with the layout. The new assembly diagram is at the Armor Technology Research Institute. You go to Chief Engineer Zhang Deming. The technicians in the workshop will understand it first and improve it.

Drawings... let the carpenters build the model first according to the drawings." Seeing that Liang Xiaolong was still here, Xie Kai took more than ten drawings from his room and said at the same time. "The data on this has not been marked yet. Based on the 59 tanks, everyone

Please discuss the size and confirm the data."

Liang Xiaolong took the drawing and nodded without much communication.

Xie Kai was much younger than him, so it felt awkward for him to obey Xie Kai's instructions.

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

"Dad, how's your excavator project going?" When Xie Jianguo came back, it was already past 12 o'clock. Seeing his father's faltering steps and haggard face, Xie Kai felt a faint pain in his heart.

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

"Director Zheng has just left. My mother has not come back from working overtime." Xie Kai said, "He came here to ask about the excavator project and said that the military is coming."

"Alas! I thought too simply before. If the problem is not solved in a short time, it will be difficult to solve it within three months." Xie Jianguo sighed.

"What's wrong?" Xie Kai believed that with Hongqi Machinery Factory's technical strength and excavator technology, it shouldn't be too difficult.

Although there is no experience to draw from, the power system engines currently on the market are not as powerful as those of the 59 tank.

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

"The hydraulic system has been designed, but the hydraulic pipes currently available in China cannot withstand the changing pressure..." Xie Jianguo is under tremendous pressure. In the factory, the pressure must be hidden, otherwise it will affect everyone's emotions.

It would be much easier to talk to my son at home.

"Hydraulic pipe? It's not a problem with the hydraulic pump?" Xie Kai looked surprised.

A small hydraulic pipe puts the entire project into trouble?

"There is no problem with the hydraulic pump, but the hydraulic pipe is not strong enough. When the excavator is working, it needs a lot of hydraulic pressure, but it cannot arrange too many hydraulic pipes..." Xie Jianguo explained.

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

Once the hydraulic pressure is insufficient, the excavator will become weak and weak.

"Separate the hydraulic lines in various parts."

"You think we don't know? The pressure is not enough and the existing pipelines cannot bear it. Once the oil pressure is too high, the pipelines will burst, causing hydraulic leaks." Xie Jianguo felt like a drowning man who couldn't hold on to a straw.

Hold tightly.

My son is only 16 years old, so no matter what, he may not necessarily know what is going on.

Xie Kai was dumbfounded.

In the past, when they were engaged in technology, the supporting domestic industrial systems have been improved accordingly. Except for materials or parts with special requirements, they can be found directly.

If you can't find it, you can also find it developed by relevant research units.

Things like hydraulic pipes are completely out of their scope.

Who would have thought that in the early 1980s, something as commonplace as a hydraulic hose would stop an entire excavator project?

"No, Dad, in the 1960s, Jiangnan Shipyard built a 10,000-ton hydraulic press. Their hydraulic pipes can withstand greater force than excavators, right?" Xie Kai really had no choice, "Domestic excavator manufacturers are better

It’s quite a lot.”

"The Jiangnan plant uses stainless steel pipes, which are hard pipes. Each joint of the excavator needs to be connected with hoses... Most domestic excavators are small and technologically backward, otherwise they would not think about introducing technology."

Xie Jianguo grabbed his hair and said distressedly.

Before the experiment, they all thought it was quite easy.

When the design was completed and verified, it was found that domestic hydraulic pipes could not withstand the huge pressure and could easily burst.

"So, the only way to solve the problem is to make hydraulic hoses yourself?" Xie Kai asked.

Xie Jianguo nodded, "The pipeline workshop in the factory has been busy working on this for several nights, but the technical strength over there..."

Xie Kai kept thinking about what the hydraulic pipes they used looked like.

He knows the materials well, and he also knows that hydraulic pipes are divided into inner rubber layer, middle rubber layer and outer rubber layer, and each layer has fine steel wire as the skeleton layer.

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

Logically speaking, the same should be true for the current domestically produced hydraulic pipes.

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

"Fourth floor." The frowning Xie Jianguo looked at Xie Kai and answered doubtfully.

"Why not add more steel wire layers? The steel wire layers are made of stainless steel wires angled at 45° and woven into a mesh shape. Each layer is coated with glue. Continue to add more steel wire layers and apply glue again. If four layers are not enough, use six layers..."

Xie Kai said.

He didn't know much about this. Anyway, many of the hydraulic hoses they used were made of six layers of stainless steel woven into a mesh.

At present, there are not many applications of hydraulic pressure in China. The most important thing is the large hydraulic press. That thing is fixed and can be realized by using stainless steel pipes.

"In this way, the pipeline will be too thick and it will easily cause damage during the work process." Xie Jianguo thought about the feasibility of his son's proposal.

"On the big arm and forearm of the excavator, stainless steel pipes are directly used to transmit hydraulic pressure, and a section of hose is used at the joints. The hydraulic hose made of stainless steel wire mesh will also have sufficient strength. The thicker the pipe, the better.

Isn't it okay to be rougher as long as it can solve the problem? Solve the problem first, and then consider other things." Xie Kai said.

Whether it was possible, he didn't know.

The hydraulic pipes were indeed very thick, and he knew this.

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

Wall thickness is not a problem, as long as it can meet the requirements and has sufficient service life.

When more advanced materials become available in the future, we will consider other options.

"Your suggestion is a good one. If it works, I'll reward you with 50 yuan!" Xie Jianguo thinks this idea is feasible, and what they considered before was a little over the top.

With an excited look on his face, he praised his son, grabbed his clothes and rushed outside.
Chapter completed!
