Era: Retired from the army at the beginning and returned home.

Chapter 118 Start Designing

Coming out of the reception room, Luo Cheng wanted to take his sister to go shopping.But Dai Qianqian suggested to visit Luo Cheng's place first.

The residence arranged by the army, if they have no other performance tasks, it is not good to live there all the time.The army may not care about the girls living in a room, and eat something in the army cafeteria every day.But it's definitely not appropriate for them to behave like this.

"Are you officially engaged?"

Zhao Qian, who was sitting in the co-pilot seat, asked the squad leader in surprise. He asked them to go out just now, but the squad leader offered to chat with Luo Cheng. How many minutes did it take?When he came out, he directly said that Luo Cheng was his partner, and the negotiation was over, and now he followed Luo Cheng directly to his house to have a look.

Dai Qianqian nodded, she also has no experience in dating.Now she is not disgusted with Luo Cheng, and she also asked Luo Cheng if he would like to, the two of them think they can get along, so what if they don't get along.And if she can't get along here, she has to accept her parents to continue to introduce her to someone when she goes home.

Two jeeps, one in front and one behind, drove to the yard.It is not unreasonable to choose this yard everywhere in this waste station. The yard may be a bit small for opening a waste station, but the road at the intersection of this yard is still relatively wide.

After entering the courtyard, Dai Qianqian followed the other art soldiers to check it out. It was definitely not comparable to the administrative compound at her home.But compared with the army, it is not bad to have such a courtyard house.

The room on the right is where Luo Cheng’s sister lives, and there is a bed and a table, and the room on the left is basically empty.Enter the main room and visit the room where Luo Cheng lives, as well as the wardrobe and desk, which is pretty good.However, seeing that the quilt on Luo Cheng's bed was not neatly folded at all, those who had served in the army might be forced to make it up, but after all, we met on the first day, so we didn't say much, and we can talk about it later.

"Luo Cheng, let's move here for a few days, see if it's okay."

Dai Qianqian pointed to the room on the left and said, there are vacant rooms here, but there is no bed.Just go and buy a bed later. If Luo Cheng agrees, he will move here from the army tomorrow and go back after contacting for a few days.

The other three saw that the squad leader planned to live here, and asked them what to do.Dai Qianqian let them choose by themselves, they can stay here for a few days, and then go back together.Or they go back first, and she lives alone for a few days.

There's nothing wrong with living in the side room. Luo Chengcheng knows where to sell second-hand furniture.Let them choose a bed, and even buy a table and stools and the like.Before, it was because I didn't have much money on me, so I didn't buy that much. I paid my wages in advance a few days ago, so it's not a big deal to buy another set of furniture.

The three people who came with the squad leader are not stupid. They go back early, not only to train every day, but also to do things.It's so relaxing here, it's like a vacation.

Now that the decision is made, don't delay, Luo Cheng has to go to the factory to do some work this afternoon, at least draw the structural diagram of the chassis.This also needs to consider configuration size, wheel height and many other issues.

Buying bowls and chopsticks is simple. The main thing is to buy briquettes. The purchase of coal briquettes is based on the shopping book. It is purchased by household, and one household can buy 220 catties.If there are more than four people in a family, you can buy 220 catties.No matter how many people there are, they can only buy so much.In some places where coal is in short supply, coal is purchased according to the number of people. The upper limit is also a maximum of [-] catties per household, but if there are few people, the ration is [-] catties per person.

The shortage of coal in Yi'an is not serious, so even if Luo Cheng is alone, he can buy according to the amount of each household.

I originally planned to borrow two baskets from the neighbor's house, but we didn't have a cart, so we bought hundreds of catties of coal to pick it up.The weight of a hundred catties is nothing to many people in this era.Xiao Yu can pick it up by herself, but she doesn't know if Shi Shi is good at it.

Dai Qianqian didn't ask Luo Cheng to borrow any baskets, she just needed Luo Cheng to take them to the place to buy, and then Luo Cheng could go to work, and the other girls in their group could handle it.

The car is padded with cardboard or other things, and then a car can be pulled back. A catty of coal costs eight per cent, and a hundred catties does not cost one yuan.Xiaoyu has 20 yuan from Luo Cheng, which is enough to buy everything.

Driving the car, Luo Cheng took them to a supply and marketing cooperative that sold furniture and a place that sold coal, and then went directly to the repair shop.Where furniture is sold, someone can deliver it for only twenty cents.

After Luo Cheng came to the repair shop, all the employees went to work, and it was already past 01:30.

When they came to the team office, Team Leader Jiang and the others were leading the assembly of the booster pump.The accessory structure of the booster pump is actually not cumbersome, because it is powered by hydraulic pressure, and an oil quantity regulating valve can be adjusted according to the size of the car structure.It can't be fixed, otherwise it can be used on a small car, but not on a large car, and vice versa.

There is also a separate oil storage tank, two pipelines, one is a high pressure pipe and the other is oil return.Why is this generally installed next to the engine, because the power of the engine is needed to drive the booster pump to rotate, that is to say, as long as the engine is started, the booster pump will start to work.

Therefore, it is difficult to turn the steering wheel of a car with this mechanical direction booster pump when the car is not started.Especially if the steering wheel of later generations is changed to be smaller, it will be even more difficult to turn.Some people will say that their car gets better even without starting. That is because later on, the car is equipped with an electronic booster pump.

For the assembly of the booster pump, Team Leader Jiang asked others to install it.I walked up to Luo Cheng and discussed with him how to install the finished product.

If this thing is not installed next to the engine, if it is suspended on the chassis, it will be particularly troublesome to operate, because it does not operate by electricity, but by the power of the engine.If you want to hang over there, you have to add a rack and pinion to connect it.

"Let's go and find Director Zhang."

"Can this matter be resolved with Director Zhang?"

"There are only two cars in the factory, one for the factory manager and one for our team. Factory manager Zhang doesn't usually work in the factory, so he doesn't use a car, and his car is also old. Naturally, he will use his car for research. If the boss uses a car, use our team's."

What he said, Team Leader Jiang nodded, it made sense.Even if there are assistance documents, it is impossible to go to other factories to ask for a car to test the booster pump.Other units have cars, which ones are not in use.

When he ran to the factory manager's office and told the story, the factory manager Zhang was so angry that he almost lost his temper. How could there be such a reason? Just because his car was old, he wanted to take it out to test new products.He himself is a car repairer, and his car is worn out on the surface, but it is in good condition.But there was no other way, the two begged desperately, the car belonged to the factory and not his own, so they donated it.

After getting the car keys, tools, pens and drawings, Luo Cheng and team leader Jiang went to remove the hood of the factory manager's car.

The fuel tank is larger than that of later generations, mainly because the fuel consumption of cars in this era is high, but there are not many gas stations.So the fuel tanks are made a little bigger.And even so, as long as you go out for a long time, the driver will directly prepare some gasoline.Put it in the car, and no one checks it, because they are afraid that the car is out of gas, and there is no way to fill it up nearby.

The engine is slightly larger, but even if it is larger than the later generations, the horsepower is not as strong as the later generations.There are water tanks, gearboxes, exhaust pipes ~~~ and so on.

To be honest, many of them are more important than the booster pump. If the booster pump is broken, it will be difficult to turn the steering wheel at most.Others get out, problems occur, and the car cannot be driven.After all, the booster pump is originally for auxiliary use.

"Remove the water tank at that time, put the booster pump in the position of the water tank, and then the pipeline will go from here and here~~ here, and then continue."

"No, Team Leader Luo, the radiator of this car has been removed, so the engine must not be burned."

"It's just taken out, the water tank is piped out, we're just testing it, just keep the lid on."

"This is a good way, but it can only be tested temporarily. Without a suitable installation location, this thing can't be installed even after it is made."

"I can't manage that much. Anyway, I'm going to build a new car. At that time, I will make the fuel tank and water tank smaller, and design a reasonable installation structure myself. Then I will get this booster pump on the new car. How to install the previous car? Leave this issue to the auto factory, and let the new cars in the factory change the size and configuration of the car."

Luo Cheng also said helplessly, unless an electric booster pump was produced, it would be too difficult and unsafe to install a mechanically powered booster pump with an external suspension.

"Leader Luo, what material do you think should be used for this high-pressure oil pipe?"

Luo Cheng understood what Team Leader Jiang meant with this question. It wasn't that Team Leader Jiang didn't know what material was good, but a question of cost.In fact, iron pipes can be used, and the cost is cheap, but the pipes will be exposed under the chassis of the car. After a long time, they will rust and corrode, and they will easily leak when they rupture.

High-density leather pipes, unless specially designed by the tire factory, ordinary leather pipes will not work at all, and will harden in a year or two.And the one made of copper is definitely the best, but there is currently a shortage of copper in the country. Regardless of the two small pipes, the cumulative cost is not cheap.

The most important thing is the shortage of copper. Once mass production is required, the approval will be a problem.

"Just use a round iron pipe. Anyway, if there is a problem with the booster pump, it won't affect too much. It will be convenient and cheap to replace it at that time."

Luo Cheng replied that if copper pipes were used, the batch of cube cars he made might not be used.And the price of the cube car is only going to sell for five thousand.The cost of the initial design, if the booster pump is added, will definitely not be able to afford more than 1000.And to pass the road test, you have to add devices.

The reversing device, spring and shock absorber, these things were not planned at the beginning, and the only thought at the beginning was how to make a car that could run.

There is no custom-made pipe, if you want to check it, you have to wait for on-site fabrication and welding.Anyway, there is no problem with the assembly of the booster pump today. Why don't you call the machinery factory and ask a welder to come over because it's still early.This pipe must be welded and sealed, otherwise there will be no pressure from oil leakage.

The other is to arrange for people to go to the steel factory to bring a batch of round steel pipes, and it is impossible for the machinery factory to send people to bring materials.

There was an explanation on the side of the booster pump, Luo Cheng went to the factory director's office again, and brought out a lot of blank paper.In fact, he can also apply for a white paper at a later stage, but to apply, he still needs to fill out a form, and after filling it out, he needs to sign the factory director.It's not as convenient as taking it directly from the factory director's office, and he won't need much.

When I came to the workshop, I looked at the tricycle in the corner, and now it is lying on its back in the corner, but I don't have time to pay attention to it today.

"Two little masters (apprentices) who are not busy, come here, the stronger ones."

He didn't deliberately designate anyone, but directly shouted at everyone in the workshop, there are so many people in a workshop, they can't just look for Wang Cheng and the others all the time.Moreover, they are also working at this time, and it is not good for those who are working to let go of what they are doing.

After so many days in the auto repair shop, Luo Cheng has gradually matured.
