Chapter 117 Start Designing

After coming out of the reception room, Luo Cheng wanted to take his sister shopping. But Dai Qianqian suggested to go to where Luo Cheng lived first.

If they don't have other performance duties in the accommodation arranged by the army, it's not easy for them to live there forever. The army probably wouldn't care about the girls sharing a room and eating in the army canteen every day. But their behavior is definitely not appropriate.

"Are you officially dating now?"

Zhao Qian, who was sitting in the passenger seat, asked the squad leader in surprise. They were asked to go out just now, and the squad leader took the initiative to chat with Luo Cheng. How many minutes did it take in total? When he came out, he directly said that Luo Cheng was his partner, and the deal was concluded. Now he followed Luo Cheng to his house to see him.

Dai Qianxi nodded, she had no experience with being a virgin. Now she is not disgusted with Luo Cheng, and she also asked Luo Cheng if he was willing. The two of them felt that they could get along, and it would be okay if they didn't get along. And if she can't get along here, she won't have to accept her parents continuing to introduce her to someone when she goes home.

Two jeeps, one behind the other, drove up to the courtyard house. It is not unreasonable for this scrap station to choose this yard. The yard may be a bit small for a scrap station, but the road at the intersection of this yard is still relatively wide.

After entering the courtyard, Dai Qianqian followed other art soldiers to check it out. It was definitely not comparable to the administrative compound at her home. But compared to the army, having a courtyard room like this is really nice.

The room on the right is where Luo Cheng's sister lives. There is a bed and a table, but the room on the left is basically empty. It was nice to enter the main house and see the room where Luo Cheng lived, as well as the wardrobe and desk. However, when I saw that the quilt on Luo Cheng's bed was not neatly folded at all, those who had served in the military might force it to be straightened. But after all, it was the first day they met and I didn't say much. We can talk about this later.

"Luo Cheng, let's move here these days. Do you think it's okay?"

Dai Qianxi pointed to the room on the left and said, there is an empty room here, but there is no bed. Just buy a bed later. If Luo Cheng agrees, he will move here from the army tomorrow and stay in touch for a few days before going back.

The other three people saw that the squad leader planned to live here and asked them what they should do. Dai Qianqian let them choose. They could stay here for a few days and then go back together. Or they could go back first and she would stay alone for a few days.

There's nothing wrong with living in a side room. Luo Chengdu knows where to sell second-hand furniture. Let them choose a bed, or even buy a table and stools. Previously, I didn't buy that much because I didn't have much money. Now that I have advanced my salary a few days ago, buying another set of furniture is not a big deal.

The three people who followed the squad leader were not stupid. They went back early because they had to train every day and also do things. It's so relaxing here, like a vacation.

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

Buying bowls and chopsticks is simple, the main thing is to buy briquettes. Coal briquettes are purchased with the help of a shopping book. They are purchased by household, and one household can buy 200 kilograms. If there are more than four people in a household, you can buy 220 kilograms. 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 220 kilograms per household, but if there are few people, the quota is 50 kilograms per person.

The coal shortage in Ngee Ann is not serious, so even if Luo Cheng is alone, he can buy according to the household amount.

I originally planned to borrow two baskets from my neighbor's house, but we didn't have a cart, so we had to go and pick up hundreds of kilograms of coal. A weight of over a hundred kilograms is not a big deal for many people in this era. Xiaoyu can pick it up by himself, but I don’t know if Shishixing is good or not.

Dai Qianqian didn't ask Luo Cheng to borrow any baskets. She only asked Luo Cheng to take them to the place where they bought it. Then Luo Cheng could go to work, and the rest of the girls could handle it.

The car should be padded with cardboard or something else, and then one car can be pulled back. A pound of coal costs eight cents, and a hundred pounds of coal costs not even a dollar. Xiaoyu had twenty yuan from Luo Cheng, which was enough to buy everything.

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

After Luo Cheng arrived at the repair shop, all the employees went to work, and it was already past one and a half.

Arriving at the team office, Team Leader Jiang and the others were assembling the booster pump. The structure of the accessories of the booster pump is actually not complicated, because it relies on hydraulic power and an oil volume regulating valve, which can be adjusted according to the size of the car's structure. It cannot 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 and two pipelines, one is the high-pressure pipe and the other is the oil return pipe. Why is this usually installed next to the engine? Because it requires the power of the engine to drive the booster pump to rotate. This means that as long as the engine is started, the booster pump will start working.

Therefore, for a car with this mechanical direction power pump, it is difficult to turn the steering wheel when the car is not started. Especially if the steering wheel of later generations is made smaller, it will be even harder to turn. Some people may say that their car gets better even if it doesn't start. That's because later cars were equipped with electronic booster pumps, so it doesn't start as long as there is electricity.

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

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

"Let's go find Factory Director Zhang."

"Can this matter be resolved by Factory Director Zhang?"

"There are only two cars in the factory, one for the director and one for our team. Director Zhang usually doesn't work in the factory, so he doesn't have a car, and his car is also a bit worn out. Naturally, we used his car to study. If the director wants to use a car, he will use our group’s car.”

What he said made sense. Team Leader Jiang nodded. Even if there are documents of assistance, it is impossible to go to another factory to ask for a car to test the booster pump. Other units have cars, but none of them are busy using them.

When he ran to the factory director's office and told the story, Director Zhang was so angry that he almost went crazy. There was no sense in it. Just because his car was old and worn out, he had to take it out to test new products. He is a car repairman himself, and his car is only shabby on the outside but performs very well. But there was no other way. The two of them begged shamelessly. The car belonged to the factory and not to him personally, 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 director's car.

The fuel tank was larger than that of later generations, mainly because cars in this era consumed more fuel and there were not many gas stations. Therefore, the fuel tanks are made larger. And even so, whenever traveling for a long distance, the driver will always prepare some gasoline. It was placed in the car and no one checked it, for fear that the car would run out of gas and there would be no gas nearby.

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

To be honest, many things are more important than the power pump. If the power pump is broken, it will be difficult to turn the steering wheel. If something else goes wrong, the car won't start. After all, the power pump is originally used for auxiliary purposes.

"When the water tank is removed, the booster pump will be placed where the water tank is. Then the pipes will be connected from here and here~~here."

"No, Team Leader Luo, if the water tank of this car is removed, the engine will still burn."

"It's just a matter of taking it out and connecting the water tank with a pipe. We're just testing it. Just don't close the cover."

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

"I can't control that much. I want to build a new car anyway. Then I will make the fuel tank and water tank smaller, and then design a reasonable installation structure myself. Then I will put the booster pump on the new car. How to install it on the previous car? Leave this issue to the car factory and let the factory change the configuration, size and structure of the new cars."

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

"Team Leader Luo, what kind of material is good for this high-pressure oil pipe?"

Luo Cheng understood what Team Leader Jiang meant about this issue. It wasn't that Team Leader Jiang didn't know what materials were good, but it was a cost issue. In fact, iron pipes can be used and are cheap, but the pipes will be exposed under the chassis of the car. Over time, they will rust and corrode, and they will break and leak easily.

Unless the tire factory specially designs high-density leather pipes, ordinary leather pipes will not work and will harden in one or two years. 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 pipelines, the cumulative cost is not cheap.

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

"Just use a round iron pipe. Anyway, if there is a problem with the booster pump, it won't have much impact. It will be easy and cheap to replace it when the time comes."

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 5,000. The cost of the initial design, if a booster pump is included, would definitely be over a thousand dollars. To pass the road test, you have to add devices.

The reversing device, spring shock absorbers, these things were not planned at the beginning. At the beginning, I just thought about how to make a running car.

There are no custom-made pipes. If you want to inspect them, you have to wait for on-site fabrication and welding. Anyway, there will be no problem in assembling the booster pump today. Why not take advantage of the fact that it is still early and call the machinery factory to arrange for a welder to come over. This pipe must be welded and sealed, otherwise there will be no pressure due to oil leakage.

In addition, it is necessary to arrange for people to go to the steel factory to bring a batch of round steel pipes. It is impossible for the machinery factory to arrange people to bring the materials.

There was an explanation for the booster pump. Luo Cheng went to the factory director's office again and brought out a lot of white paper. In fact, he can also apply for a blank paper at the later stage, but to apply, he does not have to fill out a form, and after filling it out, he has to sign it. It's better to go directly to the factory director's office to get it. He won't need much.

When I came to the workshop, I looked at the tricycle in the corner. It was still lying face up in the corner, but I didn't have time to pay attention to it today.

"Two young masters (apprentices) who are not busy will come, the one with stronger strength will come."

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

After spending so many days in the auto repair shop, Luo Cheng also began to mature.
