Siheyuan Great Craftsmen

"Grandson, why are you out? Didn't you say you wanted to draw a picture?" Grandma poked her head out of the kitchen, her eyes full of confusion, and asked Zhou Tian as he walked out with a backpack.

"Grandma, I brought you some good things, as well as things for your second uncle, second aunt, grandpa, Xiaojun, and Xiaomin!" Zhou Tian smiled and shook the backpack in his hand at his grandma. Then, he took out ten kilograms of grapes and a dozen big, bright red apples from the backpack.

"Oh, my eldest grandson, why did you buy so many fruits? Aren't you living a good life?" When the grandmother saw the apples and grapes Zhou Tian took out, her face changed slightly and she said with pity. Then, she hurried out of the kitchen, picked up the grapes and apples in her hands, and walked towards the kitchen.

"No, we can't waste it all in one meal. We have to save some!"

"Grandma, there's no need to save them. I still have a lot, don't worry!" Zhou Tian saw his grandmother's actions and hurried forward to stop her. You know, there are so many fruits in his space that even if the whole family eats them all year round, they can't finish them. How could he let his grandmother hide them?

"Okay, old woman, this is a gift from our eldest grandson to show his filial piety to us, so let's eat it. Don't be so stingy and make him laugh at you!" At this time, the grandfather came out of the house and said.

"You old thing, what do you know? This fruit is so precious. Of course I know that my eldest grandson is filial, but if he eats all the fruit in one meal, wouldn't that be a waste!" Grandma rolled her eyes at grandpa.

"Grandma, just eat it. Come, I'll feed you and see if it's sweet!" Zhou Tian said, and without saying anything, he picked a plump and juicy grape and gently fed it into grandma's mouth.

Grandma held the grapes Zhou Tian fed into her mouth, and her kind face instantly blossomed into an even brighter smile. She said happily: "Hey, you must say, the grapes picked by my eldest grandson are really sweet!"

"Is it sweet? Grandma, if it's sweet, you can eat more. I'll go wash it and everyone can eat it soon!" Zhou Tian said with a smile on his face and walked briskly towards the kitchen.

The grandmother wanted to stop him, but seeing how excited and happy her eldest grandson was, she had no choice but to put her hand down.

Walking into the kitchen, Zhou Tian just pulled out a plate and was about to wash the fruit, but he didn't expect Second Aunt to stop him and said, "Xiaotian, let me do it!"

Without waiting for Zhou Tian to say anything, Second Aunt pushed Zhou Tian out of the kitchen: "You should go sit and chat with your grandparents!"

After saying that, Second Aunt turned around and continued to work. Zhou Tian was left standing at the kitchen door, somewhat speechless.

But he didn't say anything. After this period of time, he had gradually gotten used to his family's kindness to him. Since Second Aunt had taken the responsibility, he didn't say much. He turned around and sat with Grandpa, and the two began to chat.

After a while, my cousin, his three siblings and Zhou Hao all came back from school and the meal was ready.

When all the food was served, the children cheered and sat down as they looked at the stewed chicken on the table. As Second Uncle, Zhou Jun, and Zhou Min came out of the room, everyone started to eat.

Of course, meals for Chang Wen and Chang Wu had already been reserved, and Second Aunt also sent them over.

After dinner, Zhou Tian took out some fruit, which made the children shout with joy. After instructing them to finish their fruit and do their homework, Zhou Tian returned to the house and started his own drawing project.

Three days later, in the technical department office.

As Zhou Tian put the last stroke on the cylindrical grinder drawing, he couldn't help but breathe a sigh of relief.

After arranging the drawings on the table, he finally relaxed back in his chair, closed his eyes, and soothed his exhausted spirit.

After a long time, he opened his eyes again, picked up the blueprint and walked towards the technical department.

When I arrived at the technical department and opened the door, I saw that only Dong Tianbao and Liu Wei were left in the department.

"Senior!"

"Senior!"

Seeing Zhou Tian walk in, the two of them immediately stood up and greeted him.

"Where are the others? Have they all left the workshop?"

Zhou Tian glanced at the technical department, then looked at Dong Tianbao and asked.

"Chief, isn't today the day for the assembly of the hydrostatic shaft? So they are all going to the workshop!"

Dong Tianbao immediately rushed to answer.

"Oh? That's great. I also want to see how you guys are doing. Let's go and take a look together!"

As he spoke, Zhou Tian took the blueprint, turned around and walked out of the technical department. Dong Tianbao and Liu Wei listened to the section chief's words, smiled bitterly at each other, quickened their pace, and followed closely behind the section chief.

The third workshop.

As Zhou Tian and his two companions entered the workshop, a wave of heat mixed with the smell of oil and metal surged in. The machines in the workshop were roaring, and many workers were busy at their workbenches.

Huge lathes and milling machines are neatly arranged, and the ground is covered with oil and iron filings.

Zhou Tian immediately spotted several colleagues from the technical department who were assembling a liquid hydrostatic shaft. He walked up to them and saw their focused faces. Each of them was constantly looking at the drawings and carefully checking the data.

"How's it going? Are all the parts finished?"

Zhou Tian leaned over, picked up a part and asked.

"Chief, I've checked everything, and the parts basically meet the specified requirements!"

A colleague from the technical department quickly replied.

"Well, the accuracy must be strictly controlled, and there cannot be the slightest deviation. Otherwise, the hydrostatic shaft may burst and leak oil!"

"Don't worry, Chief. We have been strictly checking and there will be no mistakes!"

"Ok!"

Zhou Tian nodded, looked at their installation steps, and frowned slightly.

"Wait a minute, this is not right. The throttle must be installed in this place. If you install it like this, oil will flow back, which will increase the consumption of the oil film and easily cause an accident!"

After watching for a while, he immediately stopped a colleague from the technical department who was installing a throttle.

"How do you think I can install it?"

After that, Zhou Tian took the throttle from the other party's hand, installed it smoothly, and then said to him: "Every step must be done correctly. In addition, the hydrostatic shaft itself is to reduce the friction of the external cylindrical grinder bearing, so we can't be careless. If there is a mistake, the entire hydrostatic shaft may be scrapped!"

"Got it, Chief!"

Upon hearing this, the colleague from the technical department couldn't help but show a trace of shame.

"Okay, although I have explained the structure of the hydrostatic shaft to you, this is your first time assembling it after all, so this is a very good result!"

Feeling the guilt in the other party's eyes, Zhou Tian comforted everyone.

"I will assemble this first one. You all just watch me and see how I assemble it!"

"Yes, section chief!"

As he spoke, Zhou Tian disassembled the liquid hydrostatic shaft that they had just assembled, and then began to assemble it step by step according to the sequence. While assembling, he explained the assembly steps to everyone, and also told them why it was designed like this and what the concept of this design was.

In fact, from the beginning, when Zhou Tian gave them three days, he had already anticipated that they would not be able to complete it so smoothly. It was not that Zhou Tian looked down on them, but he knew very well that these colleagues were not as good as students from regular colleges in terms of knowledge level or practical ability.

Even after a period of his teaching, perhaps they have almost caught up with the basics, but the overall level is still a bit far behind.

At this moment, in the third workshop, Director Yang walked in from outside, followed by Lu Guotao. When Director Yang saw Zhou Tian, ​​he was slightly stunned.

"Director Lu, why is Section Chief Zhou here?"

Hearing this, Lu Guotao stepped forward and said, "Director, during this period of time, several people from the technical department asked the factory's masters to process some parts. They said that Section Chief Zhou designed them, so they should be assembling them now!"

"Oh, let's go and take a look!"

As they spoke, the two of them walked towards Zhou Tian and his companions, one in front and one behind.

As soon as they approached, they heard Zhou Tian talking incessantly to several colleagues from the technical department about the assembly, structure and function of the liquid hydrostatic shaft.

The two did not take it seriously at first, but as they listened, they realized something was wrong. It seemed that the liquid hydrostatic axis that Zhou Tian was talking about seemed very unusual!
