Station for a well for a private house

Most homeowners in the garden build an autonomous water supply network that ensures uninterrupted supply of usable water. The main detail of water supply networks is equipment that transports well fluid from a water intake point into a house. There are a large number of varieties and modifications of pumping equipment, so it is recommended to carefully study them before buying.

Purpose and principle of operation

The appearance of the pumping station

Pumping stations are special installations that consist of two parts - a hydraulic accumulator and a surface pump. This ensures the working pressure in the pipeline, and this allows you to use the washing machine or dishwasher without interruption.

The surface pump starts automatically as soon as the water level in the accumulator (reservoir) drops, and not every time the water tap is opened. These design features protect homeowners from water shortages. Another advantage of the hydraulic tank is that in case of emergency or emergency situations there is always a supply of clean liquid from the source.

The purchase of a pumping station is advantageous in that it provides for the presence of all the necessary segments at once. As practice shows, a finished network is cheaper than a separately purchased hydraulic tank and pump.

The principle of operation of water pump units:

• A pump is turned on, which transports water to the accumulator. During this time, the working pressure in the pipeline increases significantly.
• As soon as households open any tap, the pressure in the system drops to 2.2 bar, the pressure switch activates and restarts the water pump to replenish the spent resources in the tank.
• As soon as all losses have been compensated, the pressure in the pipeline rises to 3 bar, a relay is again activated, which turns off the pump.

The principle of operation of the device is cyclical. For the productive operation of the entire system, the required amount of fluid in the intake and the presence of electricity are required.

Types of well stations for a private house

An external ejector for the pump station provides additional meters of water lift

There are several types of pumping equipment, each of which has its own technical features, as well as advantages and disadvantages. To select the appropriate system in a particular case, you need to study this issue in more detail.

Depending on the design features, the equipment is classified as follows:

• A system with a remote ejector or a submersible pump, the feature of which is to completely immerse into the well. The height of the water column does not matter, since the unit is installed directly at the water mirror. Well water is absorbed due to the Bernoulli effect indirectly. The cost of such equipment is much higher than analogues, due to its high performance and power. Install such pumping stations for wells of 40 meters or more.
• 

  Pump station with integrated ejector

  System with integrated ejector. Indirectly absorbed well fluid. The principle of operation of the device is as follows: the pump provides high pressure in the pipeline, due to which a jet is created, which, passing through the ejector nozzle in the suction chamber, creates a reduced pressure. The main advantage of this equipment is that there is no chance of idling, because it pumps water in the recirculation loop continuously.

• Direct suction system.The water unit creates a vacuum in the intake pipe, as a result of atmospheric pressure pushes water into the pipe. Difficulty in operation arises due to limited air pressure. Such pumping stations are suitable for a well of 15 meters and no more.

There are also systems that are equipped not with accumulators, but with special storage tanks, in which the cyclic nature of the water pump depends on the float mechanism. Such devices become obsolete, so you can meet them less and less.

Which station to choose

The principle of operation and placement options of the pumping station

Each well and well have their own technical features, on the basis of which the selection of equipment for the supply of water to the house in the country or in a country house should be carried out. It is necessary to pay attention to such factors:

• maximum allowable working power;
• productivity or debit of a water intake point;
• design features;
• values ​​of the optimal height of the water drop;
• equipped with cleaning filters;
• indicators of static and dynamic water levels in the well;
• pressure indicators;
• maximum depth at which the equipment can operate.

Experts recommend that you refrain from acquiring a pumping station if you have not yet completed and received a technical certificate for the well. This is due to the fact that the productive uninterrupted operation of an autonomous water supply system depends on the technical characteristics of the source.

Installation Features

In order for the system not to fail, the following recommendations for its installation must be observed:

• The interval between the well water source and the working unit must comply with the standards indicated in the technical data sheet for the equipment.
• The surface pump must stand in a heated room with the arrival of cold weather, otherwise the system will freeze and require expensive repairs.
• The room should be equipped with a good ventilation system. If this condition is neglected, the difference in ambient temperature will cause the formation of condensate in the tank.
• For the pipeline, it is recommended to give preference to polypropylene pipes, which are resistant to corrosion and are not afraid of high pressure.
• It is better to mount the equipment in a remote room, because when you turn on the engine makes a lot of noise.
• It is worth refraining from using the system to water the garden in the country. Frequent switching on and off of the equipment negatively affects the performance and shortens the life of the equipment.
• To reduce vibration, it is advised to install the pump on a thick rubber mat or cushioning pad. This is done to reduce vibration.
• During installation, it is important to take care of grounding.

As a rule, installation of equipment does not cause difficulties. High-quality models have a long service life, rarely break down and practically do not require maintenance. To prevent equipment from clogging, it is recommended to equip it with coarse filters.

The price of pumping stations for a well (20, 30 and more meters) varies in a very wide range. You can buy them in any specialized store or purchase through an online store from official representatives.
