There are different types and types of pumps for wells, then you will learn more about them, and first we will find out why a well pump is needed. With the help of this device, water is raised from great depths.
To calculate the power of a pump for water wells, you can use the calculator for calculating the power of a pump for water wells.
There are three types of well pumps: submersible pumping equipment, surface well pumps, and manual pumps.
1. First pump type (submersible) for wells used to obtain water from any reservoir. It differs from other pumping equipment in that it is immersed in water and are in water. For the manufacture of such devices, only high-quality materials are used that are able to resist corrosion. According to the way they work, they are divided into vibration and centrifugal.
Vibratory pumps simple in design and do not require special maintenance, which attracts buyers. Also, this type of pump does not have a high price, which is also a positive quality of a vibration pump. Also in such pumps there are no bearings and other rotating elements, which are the most problematic in any mechanism, and require special attention. Due to the fact that there are no rotating parts in such a pump, this reduces its heating and prevents early wear.
The mechanism of operation of the vibration pump is not complicated. The basis of his work is the creation of a magnetic space, while passing through the coil of electricity. When electricity touches the winding of the coil, a magnetic field is produced that draws in a core connected to a stem, which in turn is connected to a rubber diaphragm. The diaphragm, in turn, bends, thereby creating a reduced pressure in the middle of the pump. Water enters the chamber, and then the springs begin to work. The diaphragm returns to its normal position, which creates an excess of pressure that closes the valve. Water enters the consumer through the outlet pipe.
A submersible vibration pump is an excellent mechanism for pumping water from any containers, for watering a vegetable garden and a garden, for pumping water from a flooded basement.
Centrifugal view of a submersible pump for wells pretty famous. With the help of such a device, it is possible to extract water of different temperatures, various acidic and oily solutions. Such a pump consists of an engine, an impeller with holes for outflow and water supply is attached to its shaft. The work consists of transferring the energy of the wheel, which rotates, to the fluid, which is located between the blades. The centrifugal force helps the fluid flow into the body and creates a pressure difference. The operation of the pump does not stop, and it supplies water through the outlet pipe.
Also, these pumps are divided into: self-priming and normal suction, and they, in turn, are divided into single-stage and multi-stage. Self-priming centrifugal pumps are distinguished by the fact that their housing is located horizontally. They begin to work after the suction pipe is completely filled with air. A non-self-priming centrifugal pump must be filled with water before it is connected to electricity.
Multi-stage differ from single-stage in that they are able to develop a high pressure, while the performance remains the same.
2. Second type - surface pumps for wells. They are great for summer cottages or country houses, they can easily cope with the supply of water to such houses. But, it is worth noting that such pumps do not pump water even with the slightest pollution.
This type of pump is located on the surface, and a flexible hose is immersed in a well or well. The depth at which water is able to accumulate is 9 meters. But if you need to increase the length, you can buy ejectors. Before starting work, the pump is filled with water. Also, these pumps come with automatic on and off. Such pumps are considered more profitable, since they use much less electrics, they have protection against overheating, and they cope better with pumping water.
3. Last well pump type - manual pumps. They are also used for pumping and moving liquids that do not contain abrasive components, such units are also capable of pumping liquids such as alcohol, edible oils, paraffin, fuel. It should only be noted that in no case do such devices pump ether or carbon dioxide sulfide! The maximum allowable temperature of the pumped liquid should not exceed +80 degrees.
With a non-return valve at the end of the water supply, the suction head of the hand pump for wells is up to 9 meters.
Such pumps are an excellent option for supplying water to the pipelines of large pumping units before turning them on.
The design of such a pump consists of its body, cover, wing, suction part, lever, four valves and a shaft. It works on the principle of rotating the wing with a hand lever so that all sides participate in the process of suction or displacement, due to which the movement of the liquid occurs indefinitely.
There are many different types of hand pumps for wells, which differ in their appearance, in their technical indicators and scope. Some pumps are designed exclusively for transporting oils and fuels, while others are only capable of handling contaminated water.
Then the question arises, so which of all types of pumps is best suited for extracting water from wells. And, most likely, to solve this issue, the majority begin to go into the Internet and look for an answer to their question, but there is clearly not enough virtual information for a complete answer. So here are a few parameters by which it is best to determine the type and type of well pump that suits you. And so, when choosing, pay special attention to several points:
1. Marking the base of the borehole bottom. You can get such information from the passport of your well, which the drilling company should have given you.
2. Dynamic water level. This is quite important information that shows the well flow rate. The dynamic level is a segment from the ground to the water surface while the pump is running. The flow rate is the largest amount of fluid that the well delivers per unit of time. If a large amount of water remains above the pump after it has been running for 30 minutes, it means that the flow rate in your well is good.
3. The next item to pay attention to is the statistical water level. This is the distance that is obtained from the earth to the water surface. Before measuring the statistical water level, the water in the well should not be pumped out for some time. From the depth of your well, subtract the statistical level indicator and get the value of the borehole water column.
4. The last thing to pay attention to is the diameter of the pipe. Everyone can measure such an indicator, well, or turn to specialists for help.
