Economic benefits and advantages of installing a pumping station in a country house for a water supply and irrigation system. ⠀
⠀
The comfort of living in a modern country house primarily depends on the smooth operation of the water supply system, which has a number of specific requirements. This is ease of use, profitability, quiet operation and a long service life. One of the options for creating a reliable cottage water supply system and watering the site may be a surface pumping station. To understand the advantages and features of this equipment, you need to answer the following questions: ⠀
⠀
💡 What are the nuances of choosing a pumping station? ⠀
⠀
Thinking about choosing a pump for the cottage’s water supply system and suburban area, you need to be guided by the main rule - the equipment is selected depending on the type of source. Those. first, a well is drilled, a well is rummaged or a “needle” is clogged, and only then is a pump purchased with certain technical characteristics corresponding to the water supply source. ⠀
⠀
⠀
👉 If you neglect this rule, then a situation may arise when equipment already purchased just can not cope with the work. ⠀
⠀
First you need to make the following list, to clarify the selection criteria for pumping equipment. ⠀
⠀
So: ⠀
🔸 depth and type of water supply ⠀
🔸 dynamic and static level of the water mirror in the source from the soil surface (m) ⠀
🔸 Water supply source ⠀
🔸 distance from the water supply source to the house where the water consumers are located ⠀
🔸 how many floors in the house ⠀
🔸 number of consumers and their type ⠀
🔸 where it is planned to install a pumping station (in a house or on the street, seasonality of operation) and its level of elevation above the ground ⠀
🔸 Is watering planned for the site ⠀
🔸 required system pressure ⠀
⠀
If you do not answer all the points, then in the future this may lead to an incorrect choice of technical characteristics and power of the pumping station. ⠀

The nuances of the operation of the pumping station and the automation of the irrigation process ⠀
⠀
Why does the pump station and water supply system need a hydraulic accumulator? ⠀
⠀
⠀
⚙ A pressure switch is used to control the pumping station. When the valve opens, the pressure drops in the system (usually less than 1.5 atm.), And the relay switches on the pump. When the tap is closed, the pump continues to pump water until the pressure exceeds 3 atm, after which the relay switches off the pump. Those. Each time the valve is opened, the pump switches on. To reduce the frequency of turning on the equipment and reduce pressure surges (hydroshocks), a storage tank - a hydraulic accumulator - is placed in the system. Thus, when the tap is opened, water under pressure in the tank will flow out of the mixer until the pressure drops to 1.5 atm, and the pump turns on again. ⠀
⠀
⠀
💧 The larger the volume of the accumulator, the less often the pump will turn on, which will reduce its maximum number of starts per hour and, consequently, increase the service life of the equipment. ⠀

⠀
⠀
💦 You can use a pump station to water the lawn. For example, new generation equipment, which consists of a multistage centrifugal pump, a hydraulic accumulator and a pressure switch. A feature of a multistage pump is its optimally designed hydraulics, which allows the use of electric motors of lower power at the required performance. ⠀
⠀
🛡 Modern pumping stations are equipped with thermal protection of the electric motor, protection against “dry running”. This increases their usability and service life, which is especially true when used in the irrigation system, irrigation, as well as when using collected rainwater from storm sewers. ⠀
⠀
⚠ Important: it is not recommended to water the plants with cold well water. It is better to collect water in a container, and only when it warms up, water the plants with it. ⠀
