Installation of the pump in the well: the stages of installation and the necessary tools

Pumping water from your own well allows you to solve the problem of water supply at your summer cottage or in a country house ownership. To organize this infrastructure, it is necessary to initially prepare a well, and then select and install a pump in the place intended for operation. There are different models of pumping equipment, differing in structural, functional and basic performance. The very same installation of the pump in the well is carried out in several technological stages, including installation and electrical activities related to connecting the unit. But, to begin with, you should decide which pump can in principle be used for well water supply.

Types of pumping equipment for wells

Water delivery from a well can be provided by various pumps, including surface pumps.Another thing is that each of them will be optimal in certain conditions, taking into account the requirements for water supply. As for the surface models already mentioned, they are advantageous by the possibility of direct access to functional elements and the engine for the purpose of maintenance or regulation of operating parameters. They are not immersed directly in the wells, but carry out the fence using auxiliary equipment. The disadvantage of this type of model is a small height of water rise - no more than 10 m.

Especially for wells are designed submersible units, which have their own subspecies. In particular, centrifugal and vibration models are distinguished. Typical installation of a centrifugal pump in the well provides for the organization of a staggered water intake, provided by a wheeled suction mechanism. Each wheel includes two parallel rims, across fixed blades. Extraction and distribution of water is carried out due to the pressure that can be maintained by the hydroaccumulator.

Vibrating pumps include a vibrator and an electromagnetic device.This combination provokes the creation of high-frequency oscillations that pass through a special membrane. Actually, thanks to this work, compression and suction of water is realized with the subsequent rise.

How to choose the best pump option?

Having decided on the type of model, it is worth going to specific characteristics. To begin with, the height of the lift is determined, which will directly depend on the depth of the well. The average downhole unit is capable of delivering to a height of about 150-200 m. The most common range is 100-130 m. Next, you need to decide on the diameter of the pump casing. This is important in terms of the possibility of physical immersion equipment.

In addition to the ability of the unit to provide delivery of a resource to a certain height, it is important to calculate the volumes with which a particular pump for a well can, in principle, work. How to choose an option, for example, to serve a private house? For this assessment should be guided by the performance of the pump, given that, for example, a family of 3 people can consume about 3 cubic meters. a month at least. Accordingly, the equipment will have to at least provide this volume.Another calculation scheme is also used - with an estimate of the consumption volumes of communication consumers - cranes, household appliances, irrigation systems, etc.

Pump manufacturers

Al-ko, Metabo, Caliber, Epumps, Aquarius, FLOTEC, Jilex, etc. can be found on the domestic market. Standard solutions in the form of centrifugal units, for example, are models of TBP 5000 M from Metabo and BP18 / 3 from Epumps. Vibration plants with good reviews are located in the “Caliber” family - modifications of the NBV series. These are small-sized units that are not designed for high-performance supply, but they effectively cope with irrigation tasks. If it is not possible to purchase a powerful system from a well-known manufacturer, then the installation of the Aquarius pump will help to get into the well, which is performed according to the standard scheme and ultimately provides water lifting with a volume of about 3.5 m3/ h Of course, the Jilex models are also deservedly in demand. The company offers a line of submersible centrifugal pumps "Vodomet" and equipment "Jumbo", which focuses just on providing clean water cottages and country houses.

What you need to install the pump in the well?

Classic submersible pumps first require the use of tooling for fixing and fasteners. These devices must be prepared for immersion and installation. Next, a list of functional additions and structural components is compiled, which will be mounted together with the basic equipment. This list can be formed by fuses, protective mechanisms, automatic shutdown and regulation systems, float switches and other auxiliary devices. Directly installation of a water pump into the well is made using a complete cable and cable. When purchasing it is important to calculate that the length of these devices meets the requirements of the dive. For example, depth units intended for mines and wells usually include cables with cable lines not less than 20 m long in length. As for working inventory, it will not be superfluous to stock up with a set of electrical tools, tools for cutting and stripping wiring, and a screwdriver.

Preparation for installation work

The dive site must be cleared for convenient and safe equipment placement.The pump must be removed from the packaging, checked for leaks, the operability of functional elements and the state of electrical wiring. According to the standards, the installation of a submersible pump in the well should be carried out after the connection of the pressure pipe line has already been made. That is, the pump before immersion should be connected to the receiving circuit, from which the water supply to consumers will be supplied. Connection at this stage is implemented in two ways to choose from:

  • By means of fixing clamps, which are included in the equipment.
  • By screwing onto the nozzle. In this case, multi-adapters or other adapters may be used.

Installing a deep well pump

Working operations for the installation of pumping equipment into the well begin only after a detailed check of the characteristics of the unit and the parameters of the constructed well for compliance. This applies primarily to the depth of the dive and the diameter of the well. In the process of immersion and operation of the water intake opening should not be in contact with the filtration area or bottom.Typical installation of the pump in the well with their own hands can be a cable without the use of special equipment and installation tools. But in no case can not be used for immersion power cord - it is not intended for power loads. It is possible to place the unit at the level not less than 2 m from water. Then the cable is attached to the top of the well.

Electrical connection

Together with the cable on the surface remains the power cord that connects to the outlet. But before that, proper grounding and operation of other protective systems should be ensured. In particular, most electric pumps are equipped with highly sensitive differential switches. The plug itself must be plug-in and also double-grounded. The electrical installation of the pump in the well in addition to the insulation work involves the introduction of the complex into the automated control system. That is, through a protected relay, the user can connect the pump to the control panel. But this is only possible if the equipment initially provides for automation or programming of operating modes.

Nuances of operation

Making sure the network connection is reliable, you can put the pump into operation.If the water level is at a sufficient height, the unit will stably pump water without overheating. However, at a low level, the equipment will start to work "dry", which can cause malfunctions. It is possible to protect oneself from such phenomena either with the help of a special “dry run” mode, which many modern pump models are provided with, or with the help of a float-operated water control mechanism.

Pump maintenance

The unit should be regularly included and used for its intended purpose so that no well residues remain on its internal surfaces. Every year it is necessary to check the condition of the housing and the cable for physical damage. That is, the installation of the pump in the well should be carried out in such a way that provides the possibility of easy lifting for maintenance.

Internal surfaces are thoroughly rinsed with clean water, and stagnant contaminants should be cleaned with special detergent compositions and brushes. For more effective washing, the equipment can be immersed in a container with water (clean, of course) and turned on for a while.Attention and suction holes. Typically, the design of the lower and side parts makes it easy to dismantle the end elements and clean them separately from the main body.

Trouble-shooting

During operation, you can encounter three common problems of the equipment. These include stopping the water supply with a functioning or faulty engine, as well as intermittent water supply. In case of termination of pumping with a working engine there can be two reasons: either there is a power failure (cable damage, malfunction of the switches) or the impeller was clogged - accordingly, it will need to be cleaned. Typically, such problems arise if the pump is installed in the well just under conditions of tight contact with mud or sand, when the suction inlets become clogged. When the power unit is running, the same communications are checked, but most often such situations arise when the filter or valve is clogged. Intermittent operation may also occur in the normal state of technology - for example, when the density of the serviced fluid increases.

Finally

Technologically, the organization of domestic water supply using a well does not seem to be overly complex and inaccessible to ordinary summer residents or residents of suburban settlements. Much more important will be the initial quality of the well and the choice of equipment. As for the first point, the well should be reliable, protected from collapses and sandy dense flooring, which will not allow to ensure the operation of the pumping device. Not less responsible and the selection of the pump for the well. Which to choose? It depends on the purpose of the equipment. It is advisable to give preference to modern solutions from large manufacturers. Also, it is not necessary to select the technical specifications close to the required ones - in terms of power, productivity and feed height there should be a small margin of at least 10-15%.
