Pumps for wells
Pumps for wells - devices designedfor lifting water from great depths. As becomes clear from the name, this type of pumps are installed directly in the drilled well, but because of the large degree of immersion they received a second name - deep. Well pumps for wells are needed to ensure the water supply of private homes, buildings and public facilities, businesses, industrial buildings, as well as for irrigation and watering the garden plots. A feature of these pumps is a compact size, which allows the transportation of water from even the most narrow wells, an acceptable pressure level and long ekspluatatsii.Soderzhanie

Types and operating principles of borehole pumps
Classification of well pumps is vast: each species has its own peculiarities.
Used for lifting water from any reservoir. Unlike other species, a submersible pump is placed directly in the water. This indicates the need to use in the manufacture of high-quality materials that can effectively resist corrosion. According to the principle of operation units are divided into vibratory and centrifugal.
Class of vibration devices
To date, the most economicaloption. In addition to affordable prices, vibration-type pumps are attracted by simplicity of design and simplicity of maintenance. This type of pump equipment devoid of bearings and rotating elements - the most vulnerable parts of any mechanism requiring constant control of operation of the engine and lubrication. No rotating parts not only reduces heating of the device, but also prevents premature wear.
Principle of operation - simple. It is based on creating a magnetic space, when passing through the electrical coil. When current affects a coil, a magnetic region which draws the core associated with a rod, in turn connected to a diaphragm made of rubber.
The diaphragm bends, creates in the pump chamberlow pressure. Water enters the chamber, then - turn operation of springs. The diaphragm returns to its original position, creating an overpressure valve overlapping. Water rushes to the consumer via the outlet pipe.
Submersible pump vibration - ideal instrumentfor pumping water from the various tanks, watering gardens and orchards, for pumping water from flooded cellars and organizing water supply to industrial and domestic buildings.
Centrifugal pumps for wells
A common class of equipment with the help ofwhich can pump different fluids: hot and cold water, acid and oil solutions. The centrifugal pump comprises a motor shaft on which the impeller is mounted with openings for water supply and drainage. The principle of operation is based on the transmission power of the rotating wheel, the fluid that lies between the blades. Centrifugal force draws the fluid into the housing and creates a pressure differential. The pump thus operates continuously by feeding water through the outlet pipe.
Centrifugal pumps are self-priming andpriming, each of which is subdivided into single and multi-stage. Self-priming pumps are horizontal arrangement of the body. They begin to work when the suction pipe is completely filled with air. Priming the pump before switching on need, on the contrary, filled with water. Multistage from single stage characterized by the ability to develop high pressure, while performance remains the same.
Surface pumps for wells
Such equipment will easily provide the cottage or country house drinking water. Indispensable is under irrigation adjoining territories.
It is important! Surface pumps are not designed to pump water even a minimum degree of contamination.
The pump remains during work on the surface. a hose is lowered into the water. suction depth is 9 meters, but you can purchase additional ejectors, allowing the figure to increase. Before working surface pump must be filled with water. Models with automatic startup and shutdown system found more profitable, because consume little energy, are protected against overheating and pumped water is much better.
Units with manual control
Pumps are used to supply and transportation of liquid content without abrasive components, as well as media such as alcohol, edible oil, paraffin oil.
It is important! Inadmissibility of the use of a hand pump for pumping air or carbon sulfide. The temperature of the pumped liquid must not exceed 80 degrees.
Hand pump for the well has a suction heightto 9 m (in the presence of the check valve on the end of the water pipe). These pumps are ideal for filling of pipelines pumping installations impressive dimensions before turning. Hand pump consists of a housing cover, the wing portion of the suction, the lever 4 and the valve shaft. The principle of operation consists in the rotation of the wing by means of a hand lever, so that each of the parties involved in the suction or displacement to provide a continuous fluid motion.
There are a large number of hand pumps,different appearance, specifications and scope. Some are designed to work only with oil and fuel, while others - with the contaminated water.
What is better for the well pump?
Decided set the pump to the well or well, but you do not know which model is suitableYou? Probably the majority of trying to solve the problem, first of all sit down at the computer and try to find the answer on the Internet. Of course, the query "pumps for wells: reviews" can, and will clarify some difficult situation, but for reliable answer to the burning question of virtual information is not enough.
Parameters defining choice
So, when choosing a pump, it is necessary to pay attention to some points:
1. Mark the base of the borehole bottom. The information that can be gleaned from the well passport, issued by the drill.
2. The dynamic water level. An important characteristic of reflecting the well production. Dynamic levels - a segment of the Earth's surface to the water table during the pump operation. Flow rate - the maximum amount of liquid that the well produces per unit of time.
It is important! If the installation of the pump after working for half an hour is a considerable amount of water, therefore, a good flow rate.
3. Static water level - is the distance from the earth to the surface of the water. Before the measurement is not well should be pumped for some time. From the depth of the well figure we subtract the static level and obtain the value of borehole water column.
4. The diameter of the pipe.
These parameters can be measured independently or to resort to professional help.
What type of pump you choose?
If the distance to the surface of the water is not more than 9meters, it is possible to acquire a surface pump. The submersible pump is also nice, but be aware that the depth of the pond should not exceed 1 meter. Otherwise, instead of water, you risk silt, sand and air.
Equally important is the source of fluid. If drinking water is taken from the well, and for household needs - from the river, it is best to choose a surface pump, which can be moved, if it does not pass this number submersible.
If the depth of more than 8 meters, and the quality ofthe water is poor, then pay attention to the centrifugal pumps. When choosing a particular attention to the performance and pressure. Now that water pumps for well considered, and the corresponding device type is selected, you can proceed to the installation.
How to connect the pump to the well?
Well pump should be installed at 10 meterslower than the dynamic level. If the equipment is installed at a depth greater than 80 meters, the tube needs to 16 bar, if a depth of 80 - 12.5 atmospheres.
It is important! Be sure to install the pump unit check valve.
A brass fitting, connect the pumppump string. The transition from the pipe should be metal and have a sleeve that prevents the reduction of the pipe diameter due to voltage compression fitting.
The second end of the tube must be connected to the outputtip through the pile of brass fittings. With the help of the cable box to inform the pump with a conductive cable. Plastic clips attach the cable to the water-lifting pipe every 3 meters.
This need to know! Instead clamps are allowed to use electrical tape.
By the end walls and the pump, attach a safety wire from a stainless steel with a diameter of 5 mm. Do not use cables made of black metal and galvanized steel. Done. It only remains to lower the pump into the well.
Now that you know how to install the pump in the well, and you can enjoy the usual amenities even away from urban civilization.
