The construction of an autonomous water supply system at a summer cottage will allow you to grow a rich harvest and spend time comfortably in nature. To implement the idea, you will need a budgetary and at the same time productive pumping station, the capacity of which will fulfill the entire range of tasks assigned to it.
Types, structure and principle of operation of pumping stations
- working unit with a filter designed for water intake;
- hydroaccumulator - drive;
- a check valve that prevents the movement of water in the opposite direction;
- electric motor;
- pressure switch, which allows you to regulate the pressure of the water supply;
- suction line - a pipe connected to a pump in the well shaft;
- pressure gauge displaying accurate pressure parameters on the panel.
The principle of operation of pumping equipment is cyclical. As soon as the liquid reserves in the system run out, the device turns on and starts pumping water, filling the water supply system. As soon as the optimum pressure is reached, the relay switches off the pump. It is necessary to regulate the operation of the relay before installing the equipment, the specified indicators will depend on the technical characteristics of the model and the volume of the tank.
There are several types of water supply stations for giving from a well. It is better to give preference to units with a centrifugal and self-priming configuration, additionally equipped with an ejector. External ejector pumps are more suitable for deep wells.
How to choose a pumping station for the country
When buying a pumping station, you need to pay attention to the technical characteristics of the selected model and the parameters of the source from which it will pump water. Selection criteria to rely on when purchasing:
- Allowable liquid intake depth. It is worth analyzing not the static, but the dynamic level in the well.
- The volume of the accumulator tank. For a family of two, the optimal volume is 24 liters, for 6 or more people, you will need a container with a capacity of at least 100 liters.
- The nominal head is the conditional height of the water column that the pump is capable of providing.
- Power consumption. Consumption indicators fluctuate within 500 - 2,000 watts.
- Pumping station performance.
- Working voltage.
It is recommended to go to the store for a purchase already with knowledge of all the necessary parameters, since the purchase of too powerful or weak equipment threatens with rapid wear of parts and its failure.
Installation and connection
In the warm season, pumping equipment can be installed anywhere, the main thing is that there is a hydro source nearby. When it comes to winter, the station must be installed in a heated room.
Installation and connection rules:
- First, they begin to install the pipe supplying water to the pump, as well as the pipe supplying water to the water intake points. The pipeline is laid in trenches below the depth of soil freezing; the well needs thermal insulation.
- The end of the pipeline is equipped with a non-return valve, which prevents the movement of water in the opposite direction.
- If the source of water is a natural reservoir, it is better to additionally equip the system with a grate, which will protect the pumping equipment from foreign objects.
If, when you turn on the pumping station, tap water flows with admixtures of silt and sand, do not sound the alarm. Perhaps the well's resources have been used up, you need to wait until the water level in the well rises.
Advantages and disadvantages
Each pumping station has its own advantages and disadvantages. The biggest advantage is that all important working units are already assembled with each other, therefore, they do not need additional adjustment, installation and maintenance.
During operation, the station requires minimal financial costs. This is due to the design features. It is protected from water hammer and pressure surges.
Among the disadvantages are noisy work and the inability to install equipment without additional mechanisms at a depth of more than 8-10 meters.
The installation of a pumping station at the dacha for supplying water from a well will solve a large number of problems, the main one of which is the regularity of irrigation, which ensures a rich harvest. If you have difficulties in choosing, it is better to consult with a professional.
