At almost eight o'clock in the morning, Fang Bai walked into the classroom and heard the boys discussing the mechanical eight monsters, and only after asking did he know that his roommate had posted a couplet.

Fang Bai sat for a while, the bell rang, and the class began.

After two days of class, Fang Bai listened to the lecture while conceiving the structure of the pump.

When I was running in the morning, I suddenly found that the design idea was clear, and I started to design the ground pump.

The first step is to design the conveying speed of concrete, which is directly related to the selection of diesel engine power.

The faster the delivery speed, the more powerful the diesel engine, the higher the cost and the higher the selling price.

The conveying speed is too slow, the cost is not low, a low-power pump is cheaper and still sells for more than 100,000 yuan, and the small company is still reluctant to buy it.

Therefore, after careful consideration, Fang Bai designed the first ground pump to convey at a speed of 30 cubic meters per hour, and the size of the stone should not be greater than 30 mm.

For example, if you want to transport 30 square meters of concrete to a height of 50 meters, it is equivalent to doing work.

Each square of concrete is about 2.2 tons, about 22,000 N = 2.2WN;

30 square is 660,000 N cattle.

Work W = Fs = FH = 660,000 X 50 m = 33 million joules.

If the theoretical design vertical height is to be transported to 150 meters, that is, more than 30 stories high, the work will be greater, reaching 99 million joules.

And power: P = W/t time = 9900W/3600 seconds = 2.75W = 27.5 kW.

In fact, during the conveying process, friction occurs between the concrete and the pipe wall, and there is friction loss in the work done.

Therefore, Fang Bai calculated that the diesel engine power needs to be 45 kilowatts to be reasonable.

The second step is also directly calculated, that is, the diesel engine power;

In the third step, the working pressure is calculated according to the pipe diameter.

The diameter of the conveying pipe should not be too small, otherwise the concrete is easy to block the pipe;

Of course, it can't be too big, too big means less stress.

FANG BAI PRELIMINARILY SELECTED A PIPE WITH AN INNER DIAMETER OF 125 MM, AND CALCULATED THAT THE CONVEYING PRESSURE WAS ABOUT 15MPA.

THIS PRESSURE IS VERY HIGH, 15MPA IS 150 ATMOSPHERES!

It is necessary to choose high-pressure alloy seamless pipes, and seamless pipes with an inner diameter of 125 mm just have standard pipes, so there is no need to customize them.

Calculate the wall thickness and material strength to check if it is large enough under this pressure situation.

At the same time, considering that the concrete conveying will wear the pipe wall, it is necessary to leave enough wear margin, otherwise after a long period of use, the pipe wall will become thinner and the pipe will blow people up, and there will be not only water but also high-speed stones.

Design calculations can be a lot of work, and there are many factors to consider.

The same change directly affects other conditions.

Designing a product is not about perfection, it's about being reasonable and taking cost into account.

Otherwise, the manufacturing cost is high, the selling price will be higher, and it will be difficult to sell.

It took Fang Bai a morning to finally preliminarily determine the design factors of the first ground pump.

The main structure of the ground pump is composed of a hopper, a pump body, a hydraulic cylinder that drives the slide valve, a slide valve, a conveying cylinder, a main hydraulic cylinder and a pilot valve.

After the main design factors were determined, the next step was to design the main hydraulic cylinder and conveyor cylinder according to the diesel engine, and then design the other structures.

During class, Yang Tan sat next to Fang Bai, and saw that Fang Bai did not listen carefully to the lecture for a day, but scribbled things on a blank piece of paper, and began to draw in the afternoon.

At the end of class, Yang Tan asked Fang Bai curiously:

"Squad leader, what are you drawing?"

"Design the hydraulic cylinders." Fang Bai replied casually, without looking up, and continued to draw.

"We just got the mechanical books, and before we even started class, you were already designing and drawing?" Yang Tan was hit, the start was the same, they just fell to the ground, just about to babble, people have learned to run.

No, it's going to fly.

"I studied books during the summer vacation, and I have finished learning."

"Pervert, you're too shocking!"

After a while, many students knew that the class leader had already started drawing and designing.

Although I am not optimistic that the things designed by the class leader can be used, at least they can already draw pictures and design, and the learning speed is many times faster than that of all students.

For the next two days, Fang Bai was drawing.

There are also times when he is tired from drawing, and when he is out of school, he asks several class committee members to stay and discuss part-time jobs.

Li Kai, the secretary of the Youth League, took the lead in asking: "Squad leader, are you really doing part-time work?" ”

"You think I'm joking?" Fang Bai asked rhetorically and smiled, "Everyone is short of money to spend, and many students have a problem eating meat, since I am the class leader, I still have some business ability, which can be regarded as doing some welfare for the class."

But I only make plans and money, and the rest of the things are divided by your class committee, and then the classmates do it, make money together, share the money together, and count the money if you lose money.

Of course, the premise is that it can't affect learning, otherwise it's just picking up sesame seeds and throwing watermelons, which can be regarded as social practice in advance.

You can help collect the students who are willing to participate, if you don't participate, there will definitely be no money. ”

"Okay, squad leader, you can arrange it, I want to participate too."

"I also participated, but I don't know what you want to do, class leader."

The four class committee members have no opinions, since the squad leader has paid for it, everyone will do something.

The class leader said that there is no problem, there are many poor students, and it is difficult for many students to eat a meal of meat.

Fang Bai nodded, he had thought of several ways to make money in the past few days, analyzing and comparing.

First, open a student supermarket, students are responsible for management, there are no class hours to take turns on duty, and the main business hours have to hire people. After deducting various costs and interest, the remaining profits are apportioned according to merit.

The investment of 100,000 yuan is enough to open a 300-square-meter student supermarket, but it is difficult to find a large-area storefront.

The supply chain that needs to be found to open a supermarket is the same as opening a multiple, Xinghai Company has been preparing to open a supermarket for several months, and has found a lot of commodity supply chains, and now it is just a matter of picking out what is the best to sell.

At present, the profit of opening a student supermarket is very high, and it will not be a problem until 30 years later, and there is a lot to be done.

Second, there are no training courses in middle schools, but there are a lot of tutors. But many parents can't afford one-on-one tutoring, or can't find a satisfactory training provider.

Compared with the training institution, Fang Bai feels that he has not opened a supermarket to make money quickly.

He still has a lot of ways to make money, but it is not advisable to play too much, the same is enough, and Xinghai Company has made a lot of preparations, and what needs to be done is to keep the supply chain issue confidential.

"I decided to invest 300,000 yuan to open three open student supermarkets, respectively in Jiaotong University, Textile University, Medical University, now you need to do the work is to organize students to investigate the store, investigate what sells well, whether the store can be sold or rented, and how much is the rent."

Before Fang Bai finished speaking, the four class committee members were already dumbfounded: "Class, squad leader, really invest 300,000 yuan?" ”

"Not 30,000 yuan? 30 10,000 households? ”

"Oh my God, squad leader, you have so much money!"

Zhang Li's eyes widened the widest and roundest, she couldn't imagine that the squad leader was so rich, so how many assets his family had to have.

Fang Bai said calmly: "This is my own business and finally saved, an average of 100,000 yuan for a family, an area of about 300 square meters, it should be enough, first strive to find a store in the school, the key is the location."

Of course, the school store is not easy to get, so it is in a location with a large flow of people outside the school. ”

After finishing speaking, the expressions of the four people were still in shock.

Fang Bai slapped the table, and everyone came back to their senses.

Li Kai said excitedly: "Squad leader, I'm listening carefully, I'm just too shocked." ”

Zhang Li also looked surprised, but said with some concern: "Yes, the investment is so big, what if you lose it, don't you need to investigate?" ”

Fang Bai understood the reactions of these students, 300,000 yuan was too much in this era, and it was enough to spend four years in the hands of each student, and it was more than enough.

But he didn't plan to do it, it didn't make sense to donate money directly, it would hurt people.

It's interesting to ask his classmates to help him make money, helping others and himself.

I don't care how much money I make, I can command so many classmates to mess around with him, just be happy, people can't just make money in life.

"You don't need to research, you can just do it.

I have already done the research work, just do it according to my arrangement, and don't make your own decisions.

It's mine, but you have to listen to my arrangement. Fang Bai said seriously, 300,000 yuan is not a lot for him.

However, he hates that people are fooling around the bottom when he invests.

Now there are 60 people in the class, and if everything is to be discussed, there must be different opinions, which is definitely not okay.

Fang Bai continued: "If it is profitable, each class committee member will have a 0.8% dividend, and the other participating students will receive a 0.6% dividend each, and the work will be calculated according to the hourly salary, and the current hourly salary will be 1 yuan, temporarily subsidizing some students who need to spend money urgently."

You should list the tasks and rewards, and the students will come to you to pick up the tasks and get paid after completing them.

Let me remind you that for four years of college, you only have dividends, but not equity.

If you do something that damages the team, cancel the current year's dividends;

If there is a suspended class, dividends will be deducted, and 0.1% will be deducted for one course;

If there is a special contribution and excellent results, it will be rewarded separately.

If done well, it is not a problem to get a few thousand dollars a year per person.

If you don't meet the standard, it means that you haven't done a good job, and naturally there is no dividend.

After graduating from university, if the development goes well, I will distribute equity according to everyone's contributions in the past four years, do you understand? ”

In this supermarket, Fang Bai didn't have time to participate, so he was the shopkeeper, mainly relying on the management of his classmates, and it was natural to give dividends.

If you do a good job and become a chain store, Fang Bai will naturally benefit.

If they don't pay dividends, these students will only get dead salaries, and they won't actively engage in any chain stores, after all, expanding their territory has nothing to do with them, why are they so tired, and their work enthusiasm is poor, in fact, Fang Bai earns less.

It seems to be a loss, but in fact, there is a give-and-take.

Giving more bonuses can't solve the problem of belonging, and you can only work hard if you feel like you're doing it for yourself.

And 300,000 yuan is not much for him at all, giving someone a piece of candy has to worry about Shengmi Endou Mi hatred, there is no need, just have fun with yourself, and I don't care if my classmates are grateful to him.

If Fang Bai spends a lot of time doing it, then he will definitely make a big investment, and it is impossible to give dividends to his classmates, just give his classmates normal working expenses.

Different situations, different treatments.

"I probably understand, I don't have any opinions, as long as the squad leader points to, I'll go wherever I go, hehe." Zhang Li was the first to say that if she could get a few thousand yuan a year, it would definitely be enough to spend, and there would be a lot of savings, and she could do a lot of things.

Li Kai, the secretary of the Youth League, smiled: "Haha, that must be strongly supported, the class leader is for the benefit of the whole class, and every student is a minority shareholder." ”

"I see, squad leader, are we starting a business?"

"Sort of, you can talk to the school and see if you can apply for a store in the school."

Fang Bai reminded, "I have other investments outside the school, mainly relying on the whole class, but if there is a problem that cannot be solved, you can find me, don't look for me for general things, if you find me to solve any problem, then I simply don't invest."

This is also an opportunity for everyone to exercise, there are so many students in the class, and tasks should be assigned to the students who are good at it.

In the end, I was assessed and vetoed. ”

After finishing speaking, he took out a wad of money from his backpack, took out twenty hundred-yuan bills and slapped them on the table: "This is the preliminary activity fund, I will give it when I use it up."

Zhang Li and Li Kai are jointly responsible, and their salaries will also be deducted from them, and the four of you will discuss them, and then inform the classmates.

After I found a store, I asked people to register for a business license. ”

After Fang Bai finished speaking, everyone asked some questions, such as what is an open student supermarket, how much profit point is appropriate, and so on.

Fang Bai explained one by one, and after chatting about it, he ended the class committee meeting and put on his backpack and went back to the rental room.

At dinner in the evening, Fang Bai asked Li Xiaolong and Wang Dakai how the renovation of the house was progressing.

Fang Bai usually attends classes, and for the time being, he doesn't need Wang Dakai and Li Xiaolong to follow, so he arranges for them to supervise the decoration, and at the same time familiarize themselves with the surroundings.

After a few days, after Fang Bai finished designing the ground pump, he arranged for them to purchase spare parts for the ground pump and commissioned processing.

Regarding dividends and shares, there is a big controversy, and I guess many readers have not figured it out, thinking that giving dividends is giving shares, and it is necessary to distinguish this point. Giving dividends is actually the same as taking a high commission, and you will give more when you do a good job. The explanation in the text is very clear.

Why do some readers think that giving dividends is like giving assets to classmates?

Dividends are not equal to shares, the company has profits, and it is an after-tax profit, so students can get more money, which is actually the same as high rewards.

Giving shares, that is, giving assets, is equivalent to giving money for nothing, it's different, don't get confused.

From another point of view, there is a start-up company, the salary is only a little higher than your current company, and the scale is small, I guess you don't want to go, even if you go, after work, the company has nothing to do with you, you won't work hard, and even fish.

But when it comes to giving dividends, and even if you do well, you will have the opportunity to get shares, and if the boss doesn't stare at you, you will also take the initiative to find something to do.

If you don't do a good job, other colleagues who get dividends will say two words about you when they see it.

Besides, 300,000 yuan is just the casualness of the protagonist, one percent of the assets.

If you have 100 million yuan, take out hundreds of thousands of yuan as a reward, or donate, or buy a big toy, as long as you are happy.

Then why can't you accept a group of top talents to help you open a company and get dividends? And it also helps you make money.

In fact, it is a completely unacceptable thing to cause this feeling of disapproval, thinking that Xinghai Machinery Company may give shares to classmates and friends, which is an illusion caused by reading other books.
