60s researcher

"Of course that's good. I'm sorry to trouble you." Lu Jian was very happy. They were short on time. It happened that he would come to get the parts tomorrow morning. Zhao Lei and the others prepared other materials and got the compressor out first in the afternoon.

"No trouble, you are the technicians of our factory now, and I will trouble you to take a look at the machine if it breaks down in the future!" Director Du and Director Qian smiled very cordially, as if seeing a savior.

"This is our job, of course." Lu Jian directly agreed. After all, he is already an employee of the bicycle factory, so he must do what needs to be done.

"Okay, this one..." Director Du choked up a little. He looked at Director Qian and winked. What are the names of these people, and he didn't introduce them.

"..." Director Qian and him are old acquaintances, and he immediately understood what he meant, and his old face blushed, as if he was too angry with the technicians in the previous machinery factory and blamed them, and he didn't speak to them after revealing his identity Chances are, he doesn't even know what their names are now.

"Ahem, I was too anxious just now, didn't I introduce myself?" Director Du knew that he didn't know when he looked embarrassed, so he had to open the mouth and introduced himself abruptly.

"I'm Lu Jian, this is Zhao Lei, Xu Yan." Lu Jian knew the names of several people directly.

"Haha, they're all good names, and you can tell they're talented at first glance." Director Du boasted a few words bluntly, but Director Qian seemed to have lost his mind.Director Du was smiling, but he was about to scold Director Qian to death in his heart. What happened just now?This old money likes to save face in everything, and doesn't leave any room for it.

"..." I always feel that the atmosphere is very awkward.

"I won't delay you any longer. Your time is precious. Director Qian. Since the factory director has arranged for you, you have to make arrangements for them and do a good job in service." After speaking, Director Du glanced at Director Qian. Seeing him nodding, he was still a little worried, why he was assigned to the fifth workshop, this old money is notoriously inflexible.

"Okay, then let's go, go back and prepare the materials for you." Director Qian was reminded, and finally found his tongue, and left before he finished speaking.

Director Du heaved a sigh of relief when the people walked away, no, I still have to go and see more in the future.

Lu saw that the three returned to their small room after a while. As for Director Qian, he said that he would arrange materials for them as soon as he entered the workshop, and disappeared without a trace with the list he gave.

After closing the door to block out the sound from the outside, seeing that everyone was already seated, Lu Jian coughed lightly, planning to have a short meeting.

"Compressor, condenser, throttling device, evaporator, these are the four components of the air conditioner. The most important thing for us now is to get the compressor out."

"The most common one now is probably the piston compressor. There was a prototype in S Province in 1952. Didn't you say that a large 4L-20/8 air compressor was produced a few years ago?" Xu Yan Thinking back, there have been special reports in China before.

"Is the inertia too great? The gas pressure can't be balanced at all, and the noise is too loud."

"There are twin-screw compressors and single-screw compressors in foreign countries. Unfortunately, the technology is blocked, and we have no way to get information." Xu Yan was not annoyed by Zhao Lei's rebuttal. As far as the current level of development in China is concerned, the piston type is The only choice.

"The piston type has too many disadvantages. The twin-screw is too expensive. The best is the single-screw. Unfortunately, the parameter design of the screw and the star wheel is the core technology. We can't complete it now. We can only use the piston type." Lu Jian took out the blueprint , what he designed above is a piston compressor, but he uses multi-stage compression.

"Look at this picture. For single-stage compression, once the pressure exceeds 0.6MPa, all indicators will drop. If multi-stage compression is used, the exhaust temperature can be reduced by performing staged compression..."

Lu Jian spoke seriously, and Xu Yan and Zhao Lei listened seriously.Time slipped away quietly, but no one cared.

Dong dong, there was a knock on the door, Lu Jian stopped to take a sip of water, Zhao Lei hurried to open the door.

"Hello, my name is Jiang Wei. Director Qian is afraid that you will forget the time, so let me take you to dinner." The person who came was a dark and thin young man who looked very energetic. He smiled and showed his white teeth. With a big bag.

"Excuse me, Lu Jian is going to eat first?" Zhao Lei returned a smile showing his gums, then turned around and called out to Lu Jian.

"Okay." Lu saw that he had finished speaking just now, so he didn't refuse, and put away the things on the table.

"By the way, Director Qian asked me to give you the key. This door can be locked. There are also this and this, which are the parts that Director Qian asked me to give you." The young man named Jiang Wei took out a key from his pocket. Handed the key to Zhao Lei, and then put the bag in his hand inside.

Zhao Lei took it and looked at it, and threw it to Lu Jian. He felt that Director Qian was more considerate. After all, there are documents in the office, so it's not good if they don't lock them.

Lu Jian took the key, which was still tied with a rope.Seeing what Xu Yan was still thinking, he kicked him.

"Xu Yan, I'm going to eat, hurry up and get something." While speaking, he picked up his and Zhao Lei's lunch boxes and walked towards the door. Xu Lei followed him after recovering. When everyone came out, Lu Jian locked the door alright.

When they came out, there was no one in the workshop, and they should all have gone to eat.

"You don't have to work overtime at night, right?" Zhao Lei walked ahead and chatted with Jiang Wei.

"The supply of parts is limited, we have not worked overtime recently, and we all leave work on time."

"That's good, but everyone in your bicycle factory should have bicycles, right?"

"No, bicycles are too expensive, and tickets are needed, and few people have cars." Hearing this question, Jiang Wei quickly denied that all bicycles require tickets, and they don't have any internal purchases or sales.

"Hey, just kidding, I said..."

Lu Jian and Xu Yan were a few steps behind and did not speak. They arrived at the cafeteria after a while. It was meal time and there were many people inside.

Jiang Wei and Zhao Lei took the lead, ran in, and immediately ran to the window to look.

"Hurry up, there is steamed pork today, it's at the second window, let's hurry up and line up." After a while, the two ran back, and when Lu Lu saw them, he went to line up at the second window.

There are a lot of people in the second window. Although a serving of steamed pork costs 5 cents, but here are all workers, it is rare to eat meat, and there are many people queuing up. You can also take it home and eat with your family.

When Lu saw that they were waiting in line, there were only a dozen servings left, and they each asked for one, and each chose a vegetarian dish.After finishing my job, I happened to see a vacant seat for four, and the four of them quickly sat down.

"Hey, I'm lucky today." Zhao Lei squinted his eyes enjoying the tamales after taking a bite. This tamales are made of pork belly. It's three points thin and seven points fat. It's the favorite of people in this era, because the material is not rich. People lack fat and water, so they like fat meat.

"Yeah, it's a rare time in the cafeteria that they can make tamales, and there are so many of them. In the past, there were about 200 servings of big meat every time. Our bicycle factory has nearly 2000 people, so we can't sell them all at once. .” Jiang Wei also buried himself in hard work.

"It's not bad." Xu Yan also ate seriously.

Lu Jian ate slowly, and it was indeed not bad. The current ingredients are all original, the pork is soft and glutinous, and the rice noodles are delicate and fragrant with a sweet taste.

"Hey, you all came from the machinery factory, right? Do you know what's going on? Why did you become independent all of a sudden?" Jiang Wei ate quickly, and the meat in the bowl disappeared after a while, so he slowed down. The speed of eating, glanced at a few people, lowered his head and asked carefully.

"You don't have to think about the inside story. The bicycle factory has more than 2000 people, more than the machinery factory. It's developing so fast, it should have been assigned to it long ago." Fearing that Zhao Lei might say something wrong, Xu Yan stopped the chopsticks in his hand , took the conversation away.

"You're right. Our factory is growing fast. Last year, we recruited [-] workers. The bicycles we produce are sold all over the country. Maybe the bicycles you ride are produced by us." He said Smile happily, with complacency on your face and in your words.

Zhao Lei and Xu Yan were silent, and they were still very happy. Their bicycles were produced by Hu'an City Bicycle Factory, and they were called Hu'an brand.

Lu Jian was also silent. There was no sign of his car yet, and he didn't know if the bonus that Director Wu had mentioned earlier was still there.Those people also came at an unfortunate time, why can't they wait for his money to be sent before coming?That's a full 500 yuan, what about a year's salary?

"Where are you from?" Zhao Lei quickly changed the subject.

"I am from the countryside, from Nanhu Commune, Nanshan Town, Nanshan County."

"..." Lu Jian was a little surprised, is it such a coincidence?

"Isn't Lu Jian also from Nanshan Town?" Zhao Lei called out in surprise.

"Really, which commune are you from? I haven't met anyone from the same town as me here." Jiang Wei happily stopped the chopsticks in his hand and looked at Lu Jian eagerly.

"I'm from Nanling Commune, so I should be next door to you."

"That's very close, we can go home together in the future!" He was very happy to hear that it was the commune next door.

"Okay, but I still have to get a bicycle as soon as possible." Lu Jian was a little embarrassed, this place is closer to home, but it will not be easy to borrow a bicycle from Zhao Lei in the future, and this place is also far away from his home. Definitely going back and forth by bike.

"Don't you have a bicycle yet? It will be inconvenient to go back to Nanshan Town this time, or I will take you with me! Now I can't get a bicycle without a ticket." Jiang Wei said very enthusiastically.

"Then I will trouble you for the time being. When we switch rides, I will get a ticket as soon as possible." After thinking about it, Lu Jian has no other choice but to trouble the unfamiliar comrade Jiang first. .

"If there is any trouble, our director can talk about it. Let me take good care of you. From now on, your business will be my business. Just call me to find parts and move things." Jiang Wei patted his chest, as if everything was covered by me. The look on the body.

Lu saw several people look at each other and then smiled. This comrade looks pretty good, and it should be good to deal with him.
