How to choose a pump for a well: calculation of parameters and types of aggregatesIn houses because of the city, owning a central water supply is virtually impossible. Usually this function takes for itself a well or hole, drilled by the owners. In any case, you'll have to break your head, like raising water from the mine. With a well of problems is less: threw the weather and stretched! But with a well this room will not work. In its construction, the weather does not fit easily. The only option is to install a water pump. However, they differ according to the principle of the act. The desire, before you can choose a pump for the sake of a well, learn their collection and the features of the work, as well as the properties of the casing for which you choose the situation. About some aspects, like these, we will now talk.
Which is proud of the light when choosing a pump?
There are a number of characteristics that affect the choice of a particular pump model for the sake of the well. And you need to analyze any of the characteristics like is allowed more precisely.
Daily water stress
Before, like starting to choose a pump, you need to calculate how much water you take per day. Through this, the power of the unit and its performance are fairly subject. If your family is small (3-4 people), and there are huge gardens, it is allowed to brake for the unit, who issues 60-70 liters. in min. If there is an excess of flower beds and beds where dense watering is required, it is necessary to choose a pump more efficiently.
A clear abyss of the source
When studying pump models in the store, direct attention to the product certificate. It always indicates for what depth the given sample is calculated. Your task is to compare this information with the data of your own well. If you do not directly remember the dimensions, you can do so:
Hanging luggage for a rope or narrow twine (metal desire)
Tilt it into the well shaft until it rests on the bottom
Pull out and determine the wet and dry proportion of the twine. Wet will give a clue as to the water column in the well, and the dry one - the gap in front of the surface through the water's beginning;
Adding these two values, get the total well size.
The speed of filling the well with water (debit)
Completely calculate the debit of the well is unrealistic, since in the spring the inflow of water is rather faster, in the winter time - more slowly. However, it is possible to manage with indicative figures. Count them freely: you need to ask the acquaintances or neighbors in accordance with the site of the influential pump and start it in work for your own source.
Which number:
Check the time, because the water is completely drained out;
Notice how many hours the hole will fill up;
Divide time #2 for time #1 - the estimated debit comes out. A problem may appear, like figuring out which hole was full. Trivially! At times, dropping the same weight with which you determined the height of the column. As the testimony coincides with those that you were getting to determine the size of the mine - the hole is full. Casing liner
If the hole is just planned again, it is better to operate its four-inch hole. For the sake of designs with such a diameter of pumps, a stately surplus is sold, which can not be said about three-inch ones. They are drilled less often, that's why the equipment is not enough for their sake. Measuring the diameter of the casing is allowed by the construction tape measure, and then convert cm to inch (1 inch is approximately 2.54 cm)
The diameter of the finished well can be freely measured by yourself (in centimeters, and later converted to inches), or by contacting workers who have drilled construction for you.
The property of a drilled well
If you drilled the design yourself or are not convinced of the professionalism of the drillers, then you are looking for pumps designed intentionally near the well. Universal units, of course, will be cheaper, but they are the least effective. Occupation in the book, which is unprofessional or long-used sources are often washed with sand, and it is quite moving the work of technology. You will often have to clean the pump, well, the term of its building will be reduced. If the unit was created specifically for the sake of wells, then the clogs in the water are not causelessly horrible. If the hole was drilled by non-professionals, then it can be washed with sand. Therefore, it is better to buy special pumps, made specifically for the sake of wells, and not universal ones
We select the unit according to the peculiarities of work
If all of the above is analyzed, it is allowed to begin to familiarize yourself with the types of pumps. Based on the features of the work, all systems are divided for 2 subgroups: surface and submerged (if - deep). We will examine their differences.
Surface pumps
This type of equipment is installed for the ground, without immersion. The pump pumps the fluid through suction. The deeper is the water log, the harder it is to raise the liquid, the stronger the system is selected. Surface pumps are recommended to buy for wells, in which interval before the beginning of the water column does not exceed 8 meters. Do not buy a rubber hose for pumping out water. He will be turning on the technology will begin to crush the walls because of the rarefied air and will not miss the water. It is better to change it with a pipe with a small diameter. The present first plus surface pump: easy to install, dismantle. The surface pump can be installed unswervingly near the well, and in order to reduce its voice, it is allowed to execute the box from the tree and hide the situation there
Submersible aggregates
If you have a deep hole, the variation with the surface pump will not work. We'll have to find it between submersible units.

The technique is immersed steadily in a pipe, in an aqua log. Systems operate in accordance with the principle of water ejection. Determine which for your well needs a pump, according to the size of the well. Precise - you need to calculate for what height the unit will have to expel the water jet. For this, remember the measurements that you conducted earlier. The length of the impassive rope with a sinker is the height for which the pump will have to fly water. Add to it 3-4 m., As the pump is immersed for a couple of meters deep inside the water, and you will get the final figure. If it does not exceed 40 meters, it is likely permissible to buy ordinary, low-power pumps. Find in the passport information about the maximum depth for which you can do the order. Find out more massive submersible pumps freely: their external appearance is larger than that of low-power"brethren", and according to their weight they are heavier
Only if, according to your calculations, the height of the water rise is 60 meters, and for the sake of the pump this abyss is the largest, then this sample is better not to take. Technique is enough to do for the limit of one's own strength, because with each meter in depth productivity is reduced, and the load grows. Look for pumps designed for 70 meters of depth. This will help the equipment do without unnecessary strain and be better preserved. Suggestion! Take models with automation. If the motor overheats (after a long operation time or clogged water) or all the fluid is pumped out, the pump will shut down personally. In the unfortunate case, the motor will simply burn, while you find the problem. Of the 2 types of deep-well pumps (centrifugal and vibrating), it's best to stop for the first. Vibrational are extremely sensitive to dirty water, and in the process of work destroy the walls of the well. A centrifugal pump captures water with blades rather than a vibration of the membrane, like a vibrating one, hence it hangs unbroken and does not destroy the walls of the well.
The pump is selected for a long time, hence you search for models produced by well-known, well-established manufacturers. Here it is easier for you to find a service center in accordance with the repair and maintenance of your system.
