pumps for wells - devices for lifting water from great depths.As its name implies, this type of pumps are installed directly into the drilled hole, and due largely dive they got the second name - deep.
Well pumps for wells are needed to ensure the water supply of private homes, housing 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 and an acceptable level of pressure and long service life.
Types and operating principles of downhole pumps ↑
Classification of well pumps is vast: each species has its own peculiarities.
Submersible pumps ↑
used to lift water from any reservoir.Unlike other species, a submersible pump is placed directly into the water.This points to the need to be used in the manufacture of high-quality materials that can effectively resist corrosion.
By the principle of action units are divided into vibratory and centrifugal.
class vibration devices
today it is the most economical option.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 over the work of the engine and lubrication.The lack of moving parts not only reduces heating unit, but also prevents premature wear.
principle - simple.It is based on the creation of a magnetic space while passing through the electrical coil.When current affects a coil, a magnetic region which draws the core associated with a rod, connected in turn to a diaphragm made of rubber.
diaphragm bends, creates negative pressure chamber of the pump.Water enters the chamber, then - turn operation of springs.The diaphragm returns to its original position, creating positive pressure closes the valve.Water rushes to the consumer through the outlet pipe.
submersible pump vibration - ideal device for pumping water from the various tanks, watering gardens and orchards, to pump water out of flooded cellars and organizing water supply to industrial and domestic buildings.
centrifugal pumps for wells
common class of equipment that can be used to pump different liquids: cold and hot water, acid and oil solutions.
centrifugal pump consists of 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, a fluid that is between the blades.Centrifugal force draws the fluid into the housing and creates a pressure differential.The pump thus operates continuously feeding the water through an outlet pipe.
Centrifugal pumps are self-priming and priming, each of which is subdivided into single and multi-stage.
Self-priming pumps are horizontal body.They begin to work when the suction pipe is completely filled with air.Priming the pump before turning the need, on the contrary, filled with water.
Multistage from single-stage characterized by the ability to develop a high pressure, while the performance remains the same.
Surface pumps for wells ↑
Such equipment will easily provide the cottage or country house drinking water.It is indispensable for irrigation of homestead lands.
This is important!Surface pumps are not designed to pump water even a minimal level of contamination.
pump remains while working on the surface.The water just drops the hose.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 considered more advantageous becauseconsume little energy, are protected from overheating and pumped water is much better.
units Manual ↑
pumps are used for feeding and transporting liquid content without abrasive components, as well as media such as alcohol, edible oil, paraffin oil.
This is important!Unacceptable use of a hand pump for pumping air or carbon sulfide.The temperature of the pumped liquid must not exceed 80 degrees.
hand pump suction hole has a height of 9 meters (in the presence of the check valve at the end of the aqueduct).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 with the manual lever so that each of the parties involved in the suction or displacement, providing a continuous fluid motion.
There is a large number of hand pumps, other than the appearance, characteristics and applications.Some are designed to work only with oil and fuel, while others - from the polluted water.
What is best for the well pump?↑
decided to install a pump for the well or wells, but do not know which model is right for you?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 request "pumps for wells: reviews" Maybe a few, and clarify difficult situation, but for authentic answer to the burning question of virtual information is not enough.
parameters determining the choice ↑
So, when choosing a pump, it is necessary to pay attention to some points:
1. Mark the base borehole bottom.The information that can be gleaned from wells passports issued by the drill.
2. The dynamic water level.An important characteristic of reflecting the downhole flow rate.Dynamic level - a segment of the earth's surface to the water table during operation of the pump.Flow rate - the maximum amount of liquid that the well produces per unit of time.
This is important!If
on pump installation after working for half an hour is a considerable amount of water, so good yield.
3. Static water level - is the distance from the earth to the surface of the water.Before measurement, the well is not to be pumped for some time.From the depth of the well figure we subtract the static level and obtain the value of the 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 to select?↑
If the distance to the surface of the water is greater than 9 meters, it is possible to buy a surface pump.The submersible pump is also nice, but be aware that the depth of the pond should be more than 1 meter.Otherwise, instead of water, you risk silt, sand and air.
Equally important is the liquid source.If drinking water is taken from the well, and for business needs - from the river, it is best to choose a surface pump, which can be moved, then both submersible this will not.
If the depth of more than 8 meters and the water quality is poor, then pay attention to centrifugal pumps.When choosing a particular attention to performance and pressure.
Now that the water pumps for wells are considered, and the corresponding device type is selected, you can start the installation.
How to connect the pump to the well?↑
Well pump should be installed at 10 meters lower 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.
This is important!
sure to install the pump unit check valve.
A brass fittings to connect the pump to the pump string.The transition from the tube should be metal and have a sleeve that prevents a decrease in the diameter of the pipe due to voltage compression fitting.
second end of the pipe to be connected to the output through the pile tip brass fittings.With the cable box to inform the pump with a conductive cable.
plastic straps attach the cable to pump string every 3 meters.
This need to know!Instead
clamps are allowed to use electrical tape.
To end walls and attach the safety rope pump made of 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.
