The principle of operation of a well for water. What is the principle of operation of water wells
You can talk endlessly about what to haveown water source is good. Nevertheless, much depends on what we will use water for. At present, summer residents are forced to think about themselves. This applies not only to water, but also to heating. Let's talk about what the principle of the well works on water, how to equip it. Consider other important details.
The principle of operation of a well for water, we consider withyou a little later. Now I would like to say that it is necessary to plan the location of the future source in advance. It is desirable even during the design of the house. But we all perfectly understand that in most cases this is impossible. That is why the well is drilled long after the house was built or bought. If you plan to organize a water pipe from the well to the house, then it should be placed as close to the foundation as possible, but not at all. If the well is to be used to irrigate the country plot, it is placed in a convenient place for you. In any case, there should not be any difficulties at this stage. Well, now let's go directly to our topic.
The structure of pumping stations and the principle of their operation
There are several ways to raise water fromwells to the surface. They depend on the depth of the source. If it is about 20 meters or more, a deep-water pump with an intermediate capacity is installed. In addition, there is a pair of sensors: the upper and lower water level. When the pump is turned on, the industrial tank is filled with water, and the check valve does not allow it to go back. From there, water enters the network water supply, which, in fact, we need.
If the depth of the well is less than 20 meters,an automatic pumping station is installed. Consequently, there is no need to use an intermediate tank and an automation system. In this case, the media from the station goes directly to the house water supply. As you can see, the principle of operation of a well for water is quite simple.
Functional nodes of the well
Let's consider what elements our design consists of. There are a lot of them:
- water intake with check valve and mesh;
- suction line - water flows through it into the pump or station housing;
- centrifugal pump - works in such a way that on one side a vacuum is created to suck in the liquid, and on the other hand, the pressure to raise it;
- pressure switch;
- hydraulic accumulator - is necessary to exclude water hammers in the water supply system;
- an electric motor and a pressure switch.
It should be understood that all these nodes should workdebugged. This will make the operation of the equipment efficient and productive. It is also worth considering that there are single-tube and ejector systems. The first are easier to install, and the latter allow for a relatively small capacity of the station to lift water from a great depth. So we discussed with you what the principle of water wells is. Now we go further.
We carry out installation works
But we got close to the most interesting. The fact is that not everyone knows how to equip a water well. The problem is further aggravated by the fact that specialists who are drilling an opening in the earth do not do such work. At the end of the process, you will only see a siege pipe that looks out on the meter from the ground.
It is necessary to do a lot. Protect the pipe from freezing, dig a trench from the well to the house, etc. In this case, the trench should be under a slight slope to the well, and the suction line - without kinks and swings. If you comply with these simple requirements, then you probably will succeed. But the well for water, the principle of which we have considered, is not yet equipped, so let's move on.
Works inside the house
At this stage we will perform assemblywork pumping station in the house. First you need to choose the right place. In the priority it must be a basement. In any case, a smooth lift is required, which will protect the equipment from flooding. It's not difficult to think of something, the main thing is that the station does not touch the pipes and the foundation of the house, because in this case the noise from the pump can spread throughout the house.
Once you have installed the station, you need toto engage in laying the suction line to the well. If the trench is ready, then fine. First, prepare the ejector and proceed to assemble it. Work begins with the installation of a strainer and a non-return valve. I would like to draw your attention to the fact that without these elements the system will not function. Couplings made of bronze are used for the transitions. Pay special attention to the tightness of the connections, as this is very important. After everything is done, you can cut the casing.
The most difficult we have already done. It remains to make sure that rainwater and surface water do not enter the well. There are two ways out: use a headband or weld a small metal box with a welding machine.
A full headline costs from 2,500 to 4,500rubles, a box of metal - no more than 1 000 rubles. Further we immerse the vertical segments of the pipe into the borehole. To determine their length, you need to know the water level and add to this value of 1-2 meters. It is strongly advised not to lower the tube too low to the ground. In this case, the probability is high that the grid will very quickly get clogged, and it will have to be cleaned. Then the pressure in the tank is checked. Usually it is about 1.2-1.5 Atm. If the pressure is insufficient, the air chamber has a normal automotive nipple. So you can add air with a simple compressor or car pump. Now you know how to put a well on water. The principle of work we examined, but now - a few more important details.
How to drill a well on water with your own hands
This question is of interest to many summer residents. I would like to note right away that the goal is quite real and achievable. Moreover, if you do the work yourself, you can save a significant amount of money. However, on the way you will encounter more difficulties. First, you need to make a self-made drilling rig. There are several types: screw, cartridges and working on the hydraulic principle. The latter are automatic and manual.
In either case, it is easiest to use an auger orthe so-called cartridge, working shock. That is, he falls to the ground at the drilling point, then rises and falls back. Pretty long, but cheap and angry. In this case, you need to take care of the frame and racks, and also mount an engine, the power of which usually ranges from 1 kW or even less. In any case, it's a profitable thing - self-drilling wells. The principle of operation of pumps, depending on the type of the latter, also differs. It is not recommended to use vibrating pumps for many reasons. They are noisy and zamulivayutsya. Better use centrifugal.
How the well works and why it is poured
It is worth saying that the well is the samewell. Only some of the nuances are different. But the essence does not change at all. We have a deepening in the earth, which is flooded with water. It is taken, of course, from underwater rivers. In the case of a well, you can talk about groundwater, but it all depends on its depth. Everyone knows that if you do not give a well to fill your strength, that is, a normal water level, then it will soon run out.
The situation with the well is similar, but severalis different. The fact is that underwater rivers are replenished much faster. That is why it is possible to operate the well for a long time. But even in this case there is a risk that the water at a certain point will stop. It is still important to choose the right pump performance, so that it is not too small or, conversely, large. Of course, the more precipitation in your region annually falls out, the richer the underwater river of the well will be, this must be understood. But even severe drought does not guarantee that the water will stop. Then how lucky.
Here we are and figured out what iswell for water. The principle of work, types and arrangement - all this was considered in the article. I would like to note that before you drink water from a well, it is advisable to take it for examination. Usually the deeper the source, the purer the water, but there are also exceptions to the rules.
As you can see, there is nothing complicated in the device. The principle of operation of the well for water is already known to you. It is often possible to meet wells with a manual water lift. Their device does not presuppose the presence of any stations, automatics or sensors. But we live in the modern world, so you should always be aware of the pressure in the system, the water level, the pump condition, etc. If you decide to drill the well yourself, then with the proper approach you can save about 50% of the funds. But the matter is very painstaking, and in one day or even a week you will not cope. Although much depends on the soil and depth of the source.
