Not every suburban area is characterized by the presence of a central water supply, and therefore the owners, in order to provide themselves with a sufficient amount of water, have to engage in the construction of a well or drilling a well.
No less important is the task of lifting water from the resulting structure. There are no special questions with the well — you can raise water with the help of a gate and a bucket.
In the case of a well, it is not possible to do without the use of a special pump, which creates sufficient pressure so that the water rises to the surface.
Is there a perfect pump?
The study of the relevant literature and visiting specialized forums in the process of choosing a pump, of course, is strictly recommended, but such information will only allow you to navigate in a huge assortment of equipment. It is simply impossible to recommend a universal individual pump model, since the choice is depending on the mass of factors: diameter, well depth, possibility of using electric energy and other things. So, depending on operational conditions, we can talk about a pair of varieties of pumps for wells:
Submersible;
Superficial.
Features of surface pumps
Already from the name of the pump, we can conclude that the device does not need to be placed in the water, just place it on the surface. Certain models are mounted on a special foam foam, but a prerequisite for the operational condition is that water should not get into the motor.
Superficial watering pumps have a design, the basis of which is an electric motor whose shaft holds a pump with technological holes that provide fluid lifting. The process of the fence is provided by a hose on which there is a check valve. The quality of this element should be at a height, since depressurization will lead to a loss of performance.
Important: the owners need to be controlled so that when the device is stopped in the pump, there is water, since the idle stroke can cause equipment breakdown. If there is no water in the pump, then it is worth filling it up before performing a new launch.
Surface pumps are ideal in situations where water lies at a depth not exceeding 9 meters. The big depth of such a technique is not available. Nevertheless, there is a way to increase the depth of the fence, which consists in the use of an external ejector placed in water. During the working cycle, a certain amount of water penetrates the ejector, due to which the pressure in the hose increases and the pressure increases occurs. The use of an external ejector always leads to the fact that the device begins to work with a tangible noise and consumes a lot of energy, and therefore it can only be used in exceptional situations.
The installation of a superficial type pump does not represent any difficulties. The technique is placed near the well (ideally, it should be covered with a canopy), the hose is lowered into the water, the water is poured into the case and the device is included in the network.
Important: if the device is used in the cold season, then the mandatory operation is to warm the case, otherwise the liquid will turn into ice. Ideally, the pump is placed in the insulated caisson located underground. A simpler option is the installation of a device in a heated room located at the well.
Features of submersible pumps
Under the submersible type pumps, it is customary to mean devices that are completely or partially in water, and therefore make it possible to lift it from a huge depth exceeding 10 meters. Features of the main working part allow you to divide submersible pumps into centrifugal and vibration. The most durable will be a submersible pump, the body of which is made of high -quality stainless steel.
Important: submersible pumps cannot be used outdoors, they can work exclusively under water. A modern model with automatic protection simply will not start in the air, while for cheap pumps even short -term launch will turn out to be broken down.
Features of vibration pumps
Vibration pumps are characterized by low price. The selection of a pump for a well of this type is justified only if its depth does not exceed 50 meters. As the main working element, a membrane of flexible rubber is used on one side of which is located a cavity filled with a pumped liquid, and on the other, a special part, which provides bending. The direction of the bend determines the change in the working volume, as well as the increase or reduction of pressure. Reducing pressure leads to the opening of the inlet valve, so that water enters the housing. After that, the pressure becomes even higher, which leads to lifting water.
Features of centrifugal type pumps
This equipment is the most advanced, and therefore can be effectively used in sandy and artesian wells. Like many types of lobed pumps, centrifuges use a rotating wheel, which is firmly fixed on the shaft. The wheel is a pair of disks, between which there are curved blades directed from rotation. The water that enters the case immediately falls under the influence of centrifugal force, a significant difference in pressure is created, thanks to which the liquid enters the surface.
Features of deep pumps
Finally, such types of shock pumps as a deep pump pumps are ideal for work in artesian or sand wells, as well as in technological containers. These centrifugal pumps are characterized by significant pressure with minimal dimensions, thanks to which the equipment can work effectively even in a very narrow well. The only minus of the device is its significant cost, which is explained by the complexity of its design.
