Pumping station for the well and the well
Ensuring supply of country houses - oneof the main and the main tasks that need to be addressed first. Own well or wells on the site will allow to be completely independent of imported water or neighbors. Additionally installed a pumping station for the well or pump station to well bring comfort in a private house. Installation of pumping stations is the best solution to the issue of constant pressure water and allow to enjoy the benefits of civilization, shower, automatic washing machine and much more.

Options for water projects
There are several ways to createwater supply to the house. It depends on the production method of water, it would be the water from the well or from the well, the depth and productivity as well as the water level in the well or downhole. To choose the right pump station should know the features of their installation, completion and operating conditions, and also have a pre-prepared home water supply project.
Pumping stations of any type have similardesign and differ in the method of water sampling, carried out through a well or borehole, and performance. Fully installed and working pumping station includes a pump, pressure accumulator (tank large volume of about 80 liters), the control relay and the connecting hose. This standard, assembled at the plant, pumping station can be found at almost any store that specializes in products for country houses and cottages.
The principle of operation of pumping stations
Modern pumping stations operate in the followingmanner. After starting the pump pumps in the accumulator water and creates pressure in the entire water system, which is laid in the house. As soon as someone starts to use the tap in the bathroom, shower or just wash the dishes in the kitchen, the pressure in the system slowly drops to 2.2 bar, and operates the pressure switch, which turns on the pump. It, in turn, pumps the water back into the tank to compensate its loss, and up to 3 bar pressure, then the switch is activated again and the pump switched off. Everything is simple and concise, the main condition for the smooth operation of the pumping station is the availability of electricity and sufficient water in the water intake.
Often, pumping stations equipped centrifugal self-priming pumps with built-in ejector. This type of pump has a high pressurewater supply by 40 m and a depth of suction up to 9 m. One of the main advantages of this type of pump is a low sensitivity to air in the system. Running these pumps is not difficult. You just need to open the filler cap, fill the pump with water as long as the water does not pour over the edge, and then close the lid and turn on the pump. After the pump will pump air, it starts to feed water into the system. To get rid of excess air, you can simply open the tap or valve at the pump. Pumping station for well equipped with such a pump would be most effective in their work.
there are also Centrifugal self-priming pumps with external ejector. Such pumps are installed on the pumpstation for deep wells and boreholes. Pumping station for wells and boreholes equipped with this type of pump can pump water from a depth of 45 meters. These stations are located on the surface or in specially designated premises, and the ejector attached to the two pipes is lowered into a well or borehole. One of the tubes is designed to supply water to the ejector and to create suction, and the second - for lifting water. The disadvantage of this type of pump stations is greater sensitivity to air and contamination in the system. The advantage - such stations can be placed in the house, and the ejector lowered into the borehole or well, which is located at a distance of 20-40 meters from the house.
Pumping stations for wells or wells havecharacteristic such as the height of absorption. Some stations can lift water from a depth of 8 meters, the other from a depth of 20 to 45 meters. If the characteristics of the pump contains the depth of the suction - 8 m, it does not mean that it can not be used in the well depth of 15 M. The desired depth determines the level of water or a mirror, in other words, the level at which the water can be pumped. The fact is that the aquifer may be in deep water, and the level of groundwater at a depth of 2 - 6 meters and more. And here it comes in handy knowledge of physics, namely the rules of communicating vessels. Water under pressure with depth in the well rises to the well or level at which there are groundwater and reaches the level of occurrence of 2 to 6 meters.
In areas where the groundwater level isvery deep, and the water in the well at the level of 10 m or more, submerged pumps are used. Such pumps are lowered into the well to the water level, it is inflated and lift up. In the case of the well pump is also equipped to a sufficient depth for injection. Suction pumps often - 8 m, and push the water they are at a fairly high altitude. For example, in the well depth of 90 m the pump is installed at a depth of - 60 m.
Important! When buying any type of pump station should pay attention to its packaging. In the first place - is check valve. His presence will prevent the pump station by idling and prolong its use. Another important element - is the input filter. His presence will keep the check valve and the pump from sand and dirt. All other elements, such as a pump, control automation, the accumulator and the water connection hose are included.
Calculations for water intake pumping station
To install a pumping station of any typeYou should first find out the performance of the well or wells, the level of the water table, the possible volume of water consumed and the pressure in the system. To the well or wells can smoothly provide home water capacity of the pumping station shall not exceed the capacity of the well or wells, and at the same time be more than possible water consumption.
Summing data set of elements, you can get the water flow while the inclusion of all consumers.
After receiving the required data, you can proceed to the choice of the pumping station with the appropriate parameters, as specified in its data sheet.
Important! Data on the performance of the well or wells can be obtained experimentally. Set motor pumps or plain surface pump and measure the volume of produced water. Mirrors can learn level, lowering nut tied to a strong thread, and then remove measurements. If there is a passport to a well or wells, these data can be found there.
For year-round use of the pump station it is best to place inside a specially allocated storage room.
Indoors is distributing pipes on all points of water intake. Immediately set filters coarse and fine purification of water, pressure gauge and panel automation.
Connecting the unit to the well
Water houses on the basis of the well occursas follows. In the house or near the settling utility room, where the pumping station is located. For winter, the room temperature should not fall below 2 ° C. As has been previously stated, for the wells is better to use pumps with external ejector, as is usually well away from home.
To keep pipes from freezing in winter, theirbetter to lay in the trench to a depth of 1.8 meters. In the suction pipe set net input filter and descends below the level of the mirror. At the entrance to set the coarse filter and non-return valve to the pump. After pumping station put the fine filter and then connect a pressure gauge, pressure switch, and the rest of the plumbing. Directly connected to the control station visor.
Connecting pump station to well
After the drilled hole on the surfaceIt is the casing. Further, the connection to the well pumping station can take two ways. The first - is the construction of ancillary facilities over the well. II - Installation of the caisson. In the first case will be a little uncomfortable heat the room, if it is far away from home. And as the winter we have severe, then the heat loss will be great.
Therefore, the best solution is to Equipment caisson.
To do this, dig around the casing to a depth ofInstallation of the caisson, it is usually about 2.5 m. Poured concrete pillow, and it is installed caisson. The casing is cut off so that was about 500 mm inside the caisson. From the caisson to the house to dig a trench depth of 1.8 - 2 meters, and laid it in the underwater pipe. Pumping stations can be installed in the caisson, or in the house, it depends on the type of the station. Installation of pump station into the hole it makes sense when the pump is remote. Then, in the back room of a hydraulic accumulator remains at home, filters and a remote control station.
Modern comfort implieswashing machine, shower, bath and toilet in the house, the boiler and the many other benefits of civilization. Previously, their setup was either impossible or difficult. Today, the presence of different types of pumping stations and pumps enables previously unavailable in the comfort of a country house.
