My Doomsday Shelter Unlimited Upgrades

Upgrade direction four: Change the structure of the water tank and the way of water outlet, 500 survival points are required (underground space is required).

After a few days, the water in the water tank has exceeded the 70L mark and is slowly approaching 80.

The previous acid rain also corroded the shell of the water tank a bit, but Chen Yang used alloy as the material of the water tank at the time, and acid rain with a low acidity index was not enough to destroy the basic functions of the water tank, so it could only be done on the surface article.

Chen Yang touched the shell of the water tank and began to ponder. The acid rain last time was not 'sour' enough. If there is another more violent acid rain, this kind of open-air water tank will definitely not be able to withstand it. Even if the shell is made of alloy, it will be damaged sooner or later. A day of corrosion.

Chen Yang secretly rejoiced that the group of iron wolves didn't notice the water in the iron box during the red moon two days ago, otherwise the little water he saved would definitely not be able to keep it.

Chen Yang used to take water directly from the water tank before, but now he has to start thinking about the water supply of the shelter. The location of the water tank really needs to be changed, at least not outside.

Chen Yang has heard a little about the water supply system of modern residential buildings. After all, it is directly related to daily water supply, and it is one of the compulsory courses that everyone in society must understand.

Generally, the water tanks in buildings are designed underground or on the roof, and in high-rise buildings, the water tanks on the top floor are mainly designed.

The three or four upgrade directions of the water tank obviously correspond to the placement of the two water tanks, one on the roof and one underground.

As for what is the emergency water outlet function, it should be a special water outlet design for fire protection.

In order to prevent external debris from entering the water tank and polluting water resources, the general water supply tank must be kept strictly sealed except for the water outlet and water inlet. If you want to open the water tank, it is definitely not an easy task.

Once such a water tank breaks out of fire or an emergency causes the water pipe to fail to use normally, it is necessary to start the fire fighting water tank to maintain normal water use.

Chen Yang didn't think too much about the issue of fire before. He has always been very cautious in using fire and electricity, but Chen Yang still understands the reason why he often walks by the river without getting his shoes wet, but he didn't give priority to this issue. It's just too far ahead.

But according to the meaning of the system, as long as he upgrades the water tank to a top-level water tank, the system will automatically install a fire emergency function for him to prevent him from not using water.

Compared with the upgrade direction of the buried water tank, this upgrade direction is economical and affordable, but it does not mean that the buried water tank is not good, but that the design of the buried water tank is extremely difficult.

The selection of materials for the buried water tank has extremely strict requirements first of all. The ordinary alloy used by Chen Yang may not be qualified enough, and it may be necessary to plate a layer of anti-corrosion material through the upgrade function of the system. The return has to be [-] survival points.

Of course, the 500 survival points required for the upgrade of the buried water tank are expensive for a reason. In addition to saving space, the buried water tank is better sealed, and it is not easy to breed bacteria. It is also much more convenient to disassemble than the roof water tank.

But as the saying goes, it is easy to fill a hole and difficult to dig a hole. First of all, this upgrade requires 'underground space'. Chen Yang felt that he would have to dig for two days no matter what, and he was tired after thinking about it.

The buried water tank needs to consider the thickness of the top covering soil, and the buried water tank needs to avoid the permafrost layer. Not only that, but also a layer of concrete platform must be built after digging the pit to ensure that the water tank is placed stably underground. The water tank was put down.

After digging a hole, throw things down and fill it up again. This is not called a water tank, but a coffin.

Moreover, after the buried water tank is installed, it cannot be easily moved. There are many kinds of flowers and plants on it, and houses cannot be built, trees can not be planted, and cars cannot be passed. He has no room to recycle any drop of lost water, unless he eats up the soil next to it, which is called recycling.

In addition, remembering that there are frequent earthquakes here, Chen Yang finally decided to build a water tank on the roof and use it first, and then put the water tank underground when he has a more detailed plan in the future.

There is a place on the ground, and the roof of the shelter can be placed directly, and the water tank should not block the searchlight too much.

But the best way is to open up another floor and turn the shelter into a second-floor attic design.

Put searchlights on the roof and water tanks on the second floor. This not only expands the space of the shelter, but also effectively prevents the water tanks from being exposed to wind and sun, indirectly saving 200 survival points.

If he was alone, Chen Yang would like to get the second floor out first, but now that Jiang Yanbing is here, he has to do everything secretly.

Although the upgrade of the bathroom has already made people feel outrageous enough, at least Jiang Yanbing has not witnessed the upgrade process, and he can still use the words "Huaxia Speed" to prevaricate. Even if you jump into the Yellow River, you won't be able to cleanse yourself.

The placement of the water tank has a preliminary idea, and after the water tank is placed, the water supply system is also one of the major problems.

The water supply system is not simply connecting water tanks and water pipes to every household, simply turning on the faucet and water will flow out, but there is a booster device in it.

Older houses are equipped with water stations at the grassroots level, through which water is supplied from bottom to top. Of course, the water in the water pipes is not blown up by a person at the other end, but the water pressure must be increased by a booster device. The water is squeezed up, and this principle is somewhat similar to the pumping well Chen Yang uses now.

The only difference is that the pumping well that Chen Yang uses now is manually pressed, and the water in the water station is pressurized by a water pump, which is driven by electricity, and there is no need for a real person to do it himself.

In the past, the water pressure of many high-level faucets was very low, and a few drops could not flow out for a long time, because the bottom base station did not pressurize enough. , there is no way inside or outside.

Later, when there were more and more skyscrapers, the bottom-up water supply method was changed to two pressurization methods, one pressurization at the bottom of the building and one pressurization in the middle of the floor, to ensure that the water supply of the entire building is no problem.

In addition, the way of water supply on the roof has also become one of the mainstream methods, but no matter how the water is supplied, the pressurization device is an indispensable part of the entire water delivery process.

Make a simple water pump first, and see the survival points and effects needed for the upgrade. This is Chen Yang's current general idea.

As for making the simple water pump, Chen Yang is quite confident. This thing is much easier to make than the transformer.

Other things can be made with some plastic bottles or even cans. The most critical part is the motor.

Even a simple water pump requires a small electric motor.

Such electric motors are easy to buy before the apocalypse. You can find all kinds of treasures, cats, and other places. You can use the electric motor of a four-wheel drive vehicle, but this is the apocalypse. A rare treasure that is not easy to find.

Fortunately, Chen Yang has a system to use.

Motors belong to the category of motors, and the workbench for making motors has been unlocked when he got the generator. Although there are no ready-made water pumps to make, there are still many small motors.

Thinking of this, Chen Yang drove back to the refuge. As soon as the door opened, he saw Jiang Yanbing sitting on the bed with a flushed face and looking at his mobile phone. He didn't know what happened again.

Chen Yang picked up the slippers at the door and put them back under Jiang Yanbing's feet. Jiang Yanbing stared at Chen Yang and walked all the way, ready to fight back at any time, but this time Chen Yang was in a hurry and didn't speak, but drove back directly The bedroom, which surprised Jiang Yanbing.

Opening the workbench, Chen Yang found the option of the electric motor.

Thanks to the detailed customization function of the motor, Chen Yang customized a small motor powered by 30V voltage. Those motors powered by 5V and 10V are safer and cheaper than this kind of motor, but he only has two voltages available now, 220V and 30V.

The custom-made small motor with 30V power supply costs 100 survival points. After Chen Yang used some iron blocks and alloys, he successfully made a motor with 50 survival points.

After the motor is made, a palm-sized motor appears in the palm of the hand. The method of use is still simple, and it can be rotated when it is connected to electricity.

Chapter 57 Homemade water pump, I swear to God!

Chen Yang brought the motor to the power distribution room of the refuge, and closed the door in the same way.

Seeing Chen Yang's mysterious look, Jiang Yanbing knew that Chen Yang had serious business to do. Since her leg was injured, she couldn't help Chen Yang, at least she couldn't cause trouble, so she simply lay down on the bed and looked at her phone. Can also be more comfortable.

Chen Yang didn't care whether Jiang Yanbing was sitting or lying down. What he cared about was whether the self-made water pump could run smoothly.

Chen Yang first made a wire to connect the motor with the 30V interface of the distribution box, and the rotor at the other end of the motor immediately started to run at high speed.

"It works!"

Chen Yang was delighted.

The speed of the motor is marked on the system as 1 rpm per minute, and the up and down deviation does not exceed 450%. Through observation, Chen Yang found that the deviation of the motor speed of this motor is at least not in the second half of the deviation, and it must be a little faster than 15 rpm, but It's not much faster, just don't lose money.

As for how Chen Yang saw it, this is the experience of an old engineering student. He has seen it a lot, so he naturally has a feeling.

Such a speed is definitely not enough for making a large water pump. The speed of a general water pump is about [-] revolutions per minute.

But Chen Yang still doesn't want to make a finished product, just make a simple version first, and then upgrade slowly.

Wanting to make a finished product in one step, maybe only an old craftsman who has specialized in this industry for decades can do it, Chen Yang feels that he can't grasp it for the time being.

The principle of the simple water pump is very simple. The turbine blade is driven by the motor, and the turbine blade rotates at a high speed in the water pump, and the liquid in the water pump also starts to rotate with the blade.
