Most homeowners build an autonomous water supply network on their backyard that provides an uninterrupted supply of usable water. The main part of the water supply network is the equipment that transports the well fluid from the water intake point to the 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
Pumping stations are special installations that consist of two parts - an accumulator and a surface pump. This ensures the working pressure in the pipeline, and this allows uninterrupted use of the washing machine or dishwasher.
The surface pump turns on automatically as soon as the water level in the accumulator (reservoir) drops, and not every time the water tap is turned on. These design features protect homeowners from water scarcity problems. Another advantage of the hydraulic tank is that in case of emergency or emergency situations, there is always a supply of clean fluid from the source.
The purchase of a pumping station is beneficial in that it provides for the presence of all the necessary segments at once. As practice shows, a ready-made network is cheaper than a separately purchased hydraulic tank and pump.
The principle of operation of water pumping units:
- The pump turns on, which transports water to the accumulator. During this time, the operating 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 is triggered and re-starts the water pump to replenish the spent resources in the tank.
- As soon as all the losses have been compensated, the pressure in the pipeline rises to 3 bar, the relay is again triggered, which turns off the pump.
The principle of operation of the device is cyclical. For the efficient operation of the entire system, the required volume of liquid in the water intake and the availability of electricity are required.
Types of stations for a well for a private house
There are several types of pumping equipment, each of which has its own technical features, as well as advantages and disadvantages. To choose 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 submersible pump, the peculiarity of which is full immersion in the well. The height of the water column does not matter, since the unit is installed directly at the water surface. The well water is sucked up by the Bernoulli effect in an indirect way. The cost of such equipment is much higher than analogs, due to its high performance and power. Such pumping stations are installed for wells of 40 meters or more.
Pump station with built-in ejector System with built-in ejector. Indirect suction of well fluid is carried out. 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 nozzle of the ejector in the suction chamber, creates a reduced pressure.The main advantage of this equipment is that it excludes the possibility of idle operation, since it pumps water in the recirculation loop continuously.
- Direct suction system. In the intake pipe, the water unit creates a vacuum, as a result of which atmospheric pressure pushes the water into the pipe. Difficulty in work arises due to the limited air pressure. Such pumping stations are suitable for a well of 15 meters and no more.
There are also systems that are not equipped with hydroaccumulators, but with special storage tanks, in which the cyclic operation of the water pump depends on the float mechanism. Such devices are becoming obsolete, so you can find them less and less.
Which station to choose
Each well and well has its own technical features, on the basis of which the choice of equipment for supplying water to a house in a country house or in a country house should be made. It is imperative to pay attention to the following factors:
- maximum permissible operating power;
- productivity or debit of the water intake point;
- design features;
- values of the optimal height of the water drop;
- equipping with cleaning filters;
- indicators of static and dynamic water level in the well;
- pressure indicators;
- the maximum depth at which the equipment can operate.
Experts recommend refraining from purchasing a pumping station if the technical passport for the well has not yet been issued and received. 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
To ensure that the system does not fail, the following recommendations for its installation must be observed:
- The interval between the source of well water and the working unit must comply with the standards specified 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 expensive repairs will be required.
- The room should be equipped with a good ventilation system. If this condition is neglected, the difference in ambient temperatures will cause condensation to form 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 location, since the engine makes a lot of noise when turned on.
- It is worth refraining from using the system for watering the garden in the country. Frequent switching on and off of equipment adversely affects performance and shortens the service life.
- To reduce vibration, the pump is advised to be installed on a thick rubber mat or shock-absorbing cushions. This is done to reduce vibration.
- It is important to take care of grounding during installation.
As a rule, the installation of the equipment is not difficult. High-quality models have a long service life, rarely break down and practically do not need maintenance. To prevent the 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) fluctuates in a very wide range. You can buy them in any specialty store or purchase them through the online store from official representatives.
