At this time, Hou Baobao was pinching his waist with an ugly look on his face. When Yang Xiaotao arrived, he quickly said, "Mr. Yang, look at this, it won't take long before it breaks."
Hand it in Yang Xiaotao frowned and looked at a somewhat twisted connecting rod.
The connecting rod is an important component that connects the piston and the crankshaft. It can convert the reciprocating linear motion of the piston into the rotational motion of the crankshaft, and then use the crankshaft to give the piston a reaction force. It must withstand alternating changes during work. The power of bending.
“This connecting rod, according to the test requirements, cannot withstand too much force at all, and it has deformed in less than half a day.”
Other workers nearby also took the opportunity to express their opinions. It can be done, but the materials are not up to standard and the finished product is substandard.
"Mr. Yang, we need better materials, otherwise, the engine will be useless soon."
Listening to the questions raised by everyone, Yang Xiaotao looked serious. This time it was his own negligence. .
In his opinion, there will be no problem with the rewards given by the system.
Unexpectedly, the materials for production have become the most difficult problem.
“Let’s talk about it one by one.”
Waving his hand to interrupt everyone's discussion, Yang Xiaotao walked to the production parts and said, "This casing is too thick, right? Is there any way to solve it?"
Pang Guo said, "It's best to use aluminum alloy. This way Reduce weight and improve heat dissipation It will be better."
Yang Xiaotao shook his head slowly after hearing this, "No, aluminum alloy is too expensive. We don't have so much."
Everyone was silent. The national conditions are like this. How can they do it? Just do whatever you want?
“I see it this way.”
Yang Xiaotao looked at several modules of the main body of the engine, "The main body part is still made of cast iron, and other small parts are made of aluminum alloy."
"This can also speed up heat dissipation."
The people in Pang Kingdom have no objection.
The people behind him quickly found the drawings and marked them.
“There’s more.”
"Cylinder, the cast iron we use is not good for this. We need cast iron with higher strength and wear resistance."
Hou Baobao said seriously from the side.
"Yes."
Yang Xiaotao nodded in agreement. After all, this is an important part that carries various components, and it must be hard and strong enough.
“There are also connecting rods and crankshafts. We are using ordinary steel now. It is best to replace them with high-quality alloy steel.”
When someone spoke, Yang Xiaotao asked someone to write it down.
"There is also a piston. It is best to use heat-resistant materials."
As everyone pointed out the problems one by one, Yang Xiaotao took note of them and asked people to go to the warehouse to prepare them. Use the materials first.
After Chen Gong got the news, he came from the logistics department. After asking about the situation, he immediately contacted other factories for dispatch for some materials that were not available.
When the materials arrived, Yang Xiaotao worked with everyone to replace some parts.
Working until midnight, the parts that needed to be replaced were reprocessed, and everyone started assembling in anticipation without rest.
This time, Liu Huaimin and Wang Guodong were also watching, and even Dai Qinggang and others came to check on the situation after getting the news.
The success or failure of the engine is related to their future design direction.
When the sky lit up again, it was deserted outside the factory. A cool breeze blew in from the open door, making many people gathered inside shiver.
“Mr. Yang, it’s assembled.”
Bao Bao Hou yawned and came over to report the situation. He rubbed his eyes and his eyes were full of expectation.
Yang Xiaotao also rubbed his eyes, held the kettle in his hand, took a sip of warm water, and finally walked to the assembled engine.
The engine in front of me is very big and looks very heavy.
Although this was not designed by himself, every design is firmly imprinted in his mind.
Yang Xiaotao took out his glasses and circled around the engine.
There is no fault message.
This shows that everyone designed and manufactured the parts according to the drawings.
It was assembled without any problem.
But Yang Xiaotao knew in his heart that the real test would come later.
“Come on, add water, give it a try.”
Soon, someone found diesel and water, and after adding it to the engine, a worker stepped forward, swung the rocker and started to exert force.
Tongtong~tong~~~
A dull sound came from the engine body, and then I saw that when the diesel entered the cylinder, a row of cylinders started one by one, and then completed the work in the cylinder , drives the connecting rod and crankshaft.
When the people around saw this scene, they all excitedly clapped their hands and celebrated with the people around them.
But Yang Xiaotao frowned slightly, because the sound of the engine was a little abnormal.
Moreover, the speed of the crankshaft was not fast in his eyes.
"Pang workers, let people watch here, run all morning, and stop at noon."
Yang Xiaotao said a few words, turned around and walked to the office.
He wants to go back and lie down for a while.
Pang Guo nodded and then began to arrange people.
During this time, there cannot be a shortage of fuel.
Yang Xiaotao returned to the office and lay down in front of his desk with his eyes closed to rest.
Soon, he fell asleep.
When Lou Xiaoe, who was at work, came in, she slowed down when she saw this scene.
She heard when she was downstairs that many people stayed here all night last night, including Yang Xiaotao.
"Dad!"
"Dad, hug me."
"Brother hit me."
"No, it was my sister who told me first."
In his sleep, Yang Xiaotao listened to the noise around him and instinctively wanted to slap him. If nothing else, he wanted to beat Duanwu first.
You can't take it for granted that you beat your sister.
As a result, just when his hand was about to be raised, his body subconsciously moved and hit the leg of the table. The pain immediately made Yang Xiaotao wake up and swing his arms to move.
Lou Xiao'e looked at Yang Xiaotao making a fool of himself, covered her mouth and smiled.
"Why are you laughing?"
"I just taught you a lesson in my dream. If you don't obey, you will be beaten."
Lou Xiao'e didn't believe it. She stood up and handed the jar over. Yang Xiaotao picked it up and took two sips.
"You didn't go home last night."
"Nonsense. By the way, what time is it?"
Yang Xiaotao said, raising his hand to look at his watch , ten thirty in the morning.
“Have I slept for so long?”
loud Look, keep an eye on your side. If anything happens, I'll talk about it when I get back."
Lou Xiao'e nodded.
When Yang Xiaotao came to the door of the third workshop, he heard the sounds coming from inside and frowned.
Entering the gate, the guard of Pang Guohou was communicating with Liu Daming and others.
Liu Daming worked several shifts yesterday and didn't know the situation clearly. He only found out about it when he came this morning.
"Mr. Yang." Yang Xiaotao came forward and said hello to Liu Daming and others. Then he looked at the still running engine, took out his glasses, put them on, and inspected them carefully.
I checked the engine in the morning and found no problems. Now, after fault scanning, three red dots appeared in Yang Xiaotao's field of vision.
In other words, after running for less than six hours, something went wrong with this engine?
He wouldn't dare to produce such a machine, let alone use it for armored vehicles.
“Stop!”
Yang Xiaotao took off his glasses and said to the people around him.
Liu Daming and the others looked at each other, quickly stepped forward and turned off the accelerator, and the engine gradually stopped.
"Ready to dismantle."
Yang Xiaotao said something again, and everyone looked at each other in shock.
However, Yang Xiaotao's face was serious and his words were unquestionable, so everyone had no choice but to follow the arrangement.
Put water out of the water, oil out of the oil. Find the disassembly tools and start at any time.
Ten minutes later, when everything was ready, Yang Xiaotao started to disassemble it himself.
Not long after, Liu Huaimin and others rushed over and looked at the pile of parts on the ground in surprise.
Seeing how busy Yang Xiaotao was, everyone could only hold their breath and wait for the final result.
At noon, all the parts that made up the engine were disassembled by Yang Xiaotao. A group of people in the distance looked at the parts spread out in front of them. While sighing, they also focused on the parts that Yang Xiaotao specially picked out. .
After all the parts were disassembled, Yang Xiaotao stood up, took off his gloves, and picked up the three parts on the side.
“There are problems with these parts.”
As he said, he placed the parts in front, including a piston, a cylinder liner, and the bottom cover of the fuel tank.
Pang Guo Liu Daming and others came forward and looked at it carefully, but they could not see any problems with their naked eyes.
Pang Guo asked people to find tools and prepare for measurement.
Since it was Yang Xiaotao who found it, there is something wrong with it.
“This piston is a little deformed.”
Liu Daming inspected it and saw that the piston was slightly different from the data when it was manufactured.
With the current technical literacy of workers, there is no such big difference.
Besides, a random check and measurement will be done before assembly.
Obviously, something went wrong while the piston was working.
As Liu Daming finished speaking, Pang Guo also shouted, "This cylinder liner doesn't have much."
"Me too, there's something wrong with this cap."
After the three of them finished speaking, they looked at Yang Xiaotao at the same time.
Not only them, but also a group of people around looked at Yang Xiaotao.
This is a small problem, a small problem that cannot be seen with the naked eye, a small problem that can only be discovered by measuring with the help of tools.
Unexpectedly, Yang Xiaotao found it randomly.
This, this is not just a skill, but also a feeling of extraordinary means.
Once you try it, you will know what is right and what is wrong.
“Yes, the materials for these three parts are still not good enough.”
Yang Xiaotao found the problem and said seriously, “So, these three parts need better materials.”< br>
Liu Huaimin walked up to him, looked at the existing materials, and then shook his head and smiled bitterly. These materials are already good now. If
"our machinery factory doesn't have them, we can only ask our superiors to help." ”
"Well, I'm going to call Mr. Huang and ask them if they have a solution."
"Okay!"
The two left the workshop and ran to the office.
After a while, Yang Xiaotao dialed a phone, and soon Mr. Huang's voice came.
After explaining the situation on the phone, Mr. Huang frowned.
He knew the situation of the machinery factory. The resources and materials in the warehouse, to put it bluntly, anything in the warehouse of the First Machinery Department could be found in the warehouse of the machinery factory.
“What do you need?”
“Chief, we need materials with high wear resistance, high pressure resistance and hardness, preferably aluminum alloy.”
Mr. Huang rubbed his temples after hearing this, "Well, I'll ask someone to ask first, and I'll call you back later."
"Okay, sorry for your trouble, Chief."
< br>
After hanging up the phone, Yang Xiaotao was waiting.
Lou Xiao'e came back from the cafeteria, brought a lunch box to Yang Xiaotao, and then ate in the office.
Ring ring ring
About ten minutes, the phone rang, but it was not Mr. Huang’s voice.
"Yang Xiaotao?"
Listening to the voice, Yang Xiaotao immediately knew who it was, Mr. Zhang from the Three Machinery Department.
"Hello, Mr. Zhang."
"It's okay. Xiao Huang called just now and asked."
Mr. Zhang's voice on the phone was calm and unhurried. , "The eight-cylinder diesel engine you made is really unexpected."
"We have some aluminum alloy here, and we don't have much of the high-temperature resistant material you want. We got it from the last alliance. .”
Mr. Zhang said, Yang Xiaotao was very grateful after hearing this.
"Thank you, Chief. We have used a lot. Look."
"I will send you some in a while. If there is too much, it will be gone."
"Okay, thank you, chief."
Hang up the phone, Yang Xiaotao put down his lunch box and ran to the workshop again.
At half past one in the afternoon, a truck entered the machinery factory through the gate and came outside the workshop.
The middle-aged man who got off the car was none other than Director Zheng.
"Uncle Zheng, why are you here?"
Director Zheng smiled with emotion on his face.
Their third engine department has been busy for more than half a year, but the four-cylinder diesel engine has not yet been developed.
But in the blink of an eye, this guy came up with an eight-cylinder diesel engine, which was a slap in the face.
"I heard that you have made an engine, why don't we take this opportunity to learn."
Director Zheng said what he meant, but Yang Xiaotao took it as a joke.
Soon, the materials on the car were moved into the workshop by the comrades from the security department, and everyone started a new round of manufacturing.
“Is this a high temperature resistant material?”
Looking at the board, which was only one square meter in size, Yang Xiaotao was very curious and felt that the material looked familiar.
Director Zheng smiled on the side, "This is it."
"The copper alloy obtained from the alliance is not clear about its specific composition, but it is used by us to make aerospace equipment. Important resources."
"Listen this time. Speaking of your urgent need, Mr. Zhang gritted his teeth and squeezed out this little. To be honest, even if you have money, you can't buy it now. No matter how much you have, there is nothing left."
Director Zheng said seriously, and Yang Xiaotao stared at the orange-yellow copper alloy and suddenly thought of it in his mind.
"I'll leave, it can't be true."
