Doomsday I Have a Super Survival System - Chapter 223

The restructuring of the shelter cannot be completed in one or two days. It takes a long time, and it takes a little bit of constant revision and change.

But for now, the establishment of the four major departments and the transfer of Philip to a new position are enough.

Ankai’s next biggest task is to build Herto’s sub-base. This project, to be honest, is not much smaller than the construction of subway tunnels.

Of course, as long as a shelter is not the kind that can accommodate tens of thousands of people at the same time, the scale must not be comparable to that of a hundred-kilometer-level tunnel. This idea of ​​Ankai is just an exaggerated idea. .

The shelter below Herto will be the industrial base of the Ankai shelter in the future. The scale here is much larger than the main shelter. Most of the local survivors in Herto will eventually work here. In terms of life and the number of people, this is definitely not a small number. So the scale of the shelter must be very large, very, very large.

Moreover, there will be enough mines and enough various production lines to be built here in the future, so correspondingly, the number of generators cannot be reduced.

As mentioned more than once in the previous article, there are many types of generators provided by the system.

There are the most common gasoline generators and diesel generators, as well as very large nuclear power generators, as well as wind generators and hydroelectric generators that are slightly less efficient but very clean and easy to use. But how can I put it… Wind and water power are not available now, and the reason is very simple. The external environment does not support the erection and operation of this type of generator. Ankai can only choose relatively indoor generator sets.

However, gasoline and diesel are relatively scarce resources, so at present, he can still choose the most basic thermal power generating unit.

The so-called thermal power generating set is actually very simple in principle. It is to boil a pot of water, and then rely on the power brought by steam to drive the rotor to rotate, and generate electricity by the effect of magnetoelectric cutting. In fact, even nuclear power plants that sound very tall have the same principle. They only use nuclear reactors and steam generators to replace thermal power boilers, and nuclear fission energy to replace the chemical energy of fossil fuels.

The principle of 　　 is really simple, and it can even be described as crude.

The steam turbine generator used during the first industrial revolution is still in use on the earth until the Ankai crossover. At most, some changes have taken place in the materials of the unit, or some changes have taken place in the structure, or The use of the high-end concept of “nuclear” can be found at the root of the steam engine, which has not changed much in essence.

Including gasoline generators and diesel generators, if you insist, the basic principles of steam generators have not changed much, including the way of doing work, at most, from the boiler boiling water to the combustion atomized oil directly produced. High temperature gas, that is, the difference from steam engine to internal combustion engine.

As for the generator itself.

The steam turbine generator of a thermal power plant or a nuclear power plant basically adopts a horizontal structure, which looks like a giant steel beast lying on the ground. It is composed of a generator, a steam turbine, an exciter, etc., and it operates coaxially. The most basic components of the turbo-generator set are the stator, rotor, excitation system and cooling system.

The generator set provided by the 　　 system looks like this, but the size is much smaller than that of a large generator set, and it is a reduced version at first glance.

But this time Ankai is going to make a large one directly. Although the small one saves space, the work efficiency is definitely not better than that of the large-scale unit. Otherwise, why should the power plants build large-scale units instead of many small units? Apart from other things, in terms of management alone, a large unit is much easier than many small units combined.

Large generators are more complicated to manufacture. Several major components need to be manufactured in batches by Ankai.

Fortunately, the model can be put down directly, but it is impossible to fill in all the materials in one go, and then complete the manufacturing in one go.

Of course, this is also good. Ankai can learn more about generators through this manufacturing process.

When he got a generator before, he didn’t take a good look at its internal structure. Now it is a good opportunity to get a large generator set.

For example, he didn’t care about it before. The stator core, an important component that forms the magnetic circuit and fixes the stator windings, is usually made of cold-rolled silicon steel sheets with a thickness of 0.5mm or 3.5mm and good magnetic permeability.

The size of the stator core of a large steam turbine generator is very large. The silicon steel sheets are punched into a fan shape, and then multiple sheets are assembled into a circle.

The stator windings are embedded in the stator slots in the inner circle of the stator core, arranged in three phases, forming an angle of 120° to each other to ensure that the three-phase stator windings generate electromotive force with a phase difference of 120° when the rotor rotates.

There are two upper and lower insulated conductors in each slot, and each bar is divided into a straight part and two terminal parts.

The straight line part is the effective side of the conductor that cuts the magnetic lines of force and generates the induced electromotive force, and the wire rod end part plays a role of connection, connecting the related wire rods according to a certain rule to form the generator’s stator three-phase winding.

The stator bars of medium and small turbo-generators are all solid bars, while large turbo-generators need to use internally cooled bars due to the need for heat dissipation, such as several solid bars and hollow cores that can pass water Wire rods are composed in parallel.

The rotor is mainly composed of the rotor core, field winding, guard ring and fan, etc. It is also one of the most important parts of the steam turbine generator.

Due to the high speed of the turbo-generator, the centrifugal force on the rotor is large, so the rotor is elongated and made of hidden pole type to better fix the field winding.

The generator rotor body is made of alloy steel with high strength and good magnetic permeability. Ankai can barely supply this at present. Although he has not found many rare minerals and the exchanged materials are all ordinary, he is just like that. Various underground structures are being manufactured continuously, and the squeezed out of the mud and sand contains a lot of metal particles.

is just too difficult to extract, so no one collects rare metals in this way. But in front of the system, these problems are not a problem. At least when the system squeezes out the dirt, sand and gravel, it has automatically aligned and classified it.

The excitation winding is a concentric winding composed of several coils, and the coils are wound with rectangular rectangular copper wire. After the excitation winding is placed in the slot, the straight part of the winding is compressed with a slot wedge, the end is fixed by a guard ring in the radial direction, and a mica block and a center ring are used for the axial fixation. The lead wire of the excitation winding is connected to the collector ring via a conductive rod, and then led out through the brush.

The speed of the turbo generator is very high, and the end of the field winding bears great centrifugal force, so it is necessary to use a guard ring and a center ring to fasten it.

The guard ring tightens the end of the excitation winding so that the end of the winding does not undergo radial displacement and deformation; the center ring is used to support the guard ring and prevent the end from moving in the axial direction.

The collector ring is divided into positive and negative collector rings, which are made of hard and wear-resistant alloy forged steel and are installed on the outside of the excitation end of the generator rotor. The positive and negative collector rings are respectively connected to both ends of the excitation winding through lead wires, and are led to the generator excitation system by means of a brush device.

Finally, there is a fan, which is installed at both ends of the generator rotor to speed up the circulation of the gas in the stator core and the rotor part and improve the cooling effect.

As for the cooling system of the generator, this Ankai didn’t pay much attention to it. There is also a waste heat utilization system. He just glanced at it and ignored it.

He only needs to understand the internal structure of the generator. He is not an electrical engineer, nor is he a generator set designer. Knowing too much is actually meaningless. It is purely out of curiosity. In addition, large generator sets are more special. He paid a little attention to the way of making.

Also, the large generator set is different from the previous small generator set, that is, the boiler structure is different.

Small generator set, a generator is a unit, the boiler and generator are integrated, including the combustion chamber, etc., each time it needs to replenish fuel, it needs to be supplemented one by one. Of course Ankai can also get a fully automatic installation device, but that requires a lot of materials, especially electrical parts, which is currently in short supply. In the past, although the electricity consumption in the shelter was not small, three to five small generators were enough to cope with it. Therefore, Carter has always used manual feeding, automatic feeding and so on, which is too extravagant.

But large units are different.

Large-scale units, boilers are separated separately, the steam produced by boiling water will travel along the pipeline. As long as the pressure is high enough, several large-scale units can be connected in series to generate electricity at the same time.

Of course, the best way is actually a single generator set with a boiler.

But even so, large-scale units have advantages. Because the boilers are additionally set up, it is possible to adjust their positions artificially during manufacturing. Put multiple boilers together. Within a short distance, it is possible to adjust the position of several boilers. In the case of fuel injection and comprehensive consideration of the generator power, the efficiency is undoubtedly higher than that of a small unit, and it is more convenient to use.

On the side of the industrial base, Ankai put down five large-scale units at one go to ensure that there will be no shortcomings for a long time.

The generator set is ready, and then the mine.

Mine is a general term for shafts, chambers, equipment, ground buildings and structures according to the normal understanding, but in the system, the mine corresponds to the so-called mining machinery. In this regard, perhaps considering labor and safety issues, the system is mainly recommended to use fully automatic mechanical equipment. Of course, it is also possible to manufacture excavators or drill bits under normal conditions, but unless there are really enough manpower in the shelter, for Ankai, it is actually appropriate to build mines directly.

The first-class mines are the kind of small mines on the main base, which can only produce a few ore per hour, and the efficiency is actually not high.

The advantage is that it occupies a small area, consumes less energy, and is very convenient to make, and there is no noise in operation.

But in that case, it is only easier to use when a small amount of mineral resources is used. If it is really a large-scale mining, then only large-scale mines and artificial actual drilling equipment are the best use.

Realistic drilling equipment, for now, forget it.

It is not only the manpower problem, but also the professional and safety problems.

In terms of professional issues, there is always someone in charge of prospecting, someone in charge of mining, someone in charge of ore washing and transportation and other processes. Although Herto is an industrial city, the population group is established, and miners are also a large type. But now that the end is coming, how many real miners are left is unknown, and some relatively professional jobs are definitely not something ordinary miners can do.

Safety issues are even more important. Iron mines and copper mines are actually relatively easy to talk about. The main concern is landslides and sinkings. But like coal mines, that is dangerous.

Gas explosions, coal dust explosions, etc. If there is no professional safety measures, it is impossible to say that if it affects the development of the shelter and kills a bunch of people at once, An Kai will definitely not be able to accept it.

Therefore, the best way is to use automatic mines. The biggest advantage of automatic mines is not in efficiency, but in terms of safety. The problems that are prone to common mining accidents will basically not occur in fully automatic mines. This is the only point. Let Ankai not make other choices.

Large mines occupies a large area. Just the mechanical equipment on the ground, one is equivalent to the area of ​​20 small mines.

The underground part is even more so.

Like the previous Ankai, the behavior of finally creating three mines against an aluminum mine. Small mines are okay, but for large mines, it’s impossible.

One is enough, otherwise the mines will start to collide and compete with each other.

Because the mine operation is fully automatic~www.mtlnovel.com~, it is difficult to adjust.

A large mine consumes a lot of electricity, and it needs to be supported by the equivalent of two-thirds of the electricity generated by a large generator set. Of course, the output is also very fierce. According to the system prompts, the efficiency of a large mine is 30 times that of a small mine. About doubling, spitting out dozens of ore in an hour is like playing.

I want to explain here that this ore is an ore that is automatically cut and excavated by the mine and meets the system standard for a unit size. In other words, a large mine can produce dozens of units of ore or coal in one hour, and these dozens of units of coal are enough for the five large-scale units, and there is even a surplus.

It can be seen that the creation of a system cannot be separated from the “big is beautiful, more is good” approach.

Of course, Ankai first uses coal mines as the main mining products. After all, it is necessary to run the generator set first. In addition, a series of equipment such as water collectors, air purifiers, lamps, etc. all need power support. Fortunately, when he came, the train was filled with various metal materials. At this moment, it was enough for him to carry out the initial construction.

At the same time, the two groups of Kent and Master also left the shelter from the transfer station. They drove a powered caravan and officially headed to Herto.

After two months of preparation, the physical fitness of the two groups of men and horses has been improved or recovered to a certain extent. At the same time that Ankai was working hard to build an industrial base, they started the Herto penetration plan.
