The modern market offers the buyer a large number of pumps. They differ from their counterparts in many ways. Each of them has its own functionality. Of course, this can only be welcomed, but when buying, the buyer gets into a somewhat difficult position. It is extremely difficult for him to understand this diversity.
Types of well pumps
Similar aggregates can be classified as follows:
• Centrifugal principle of operation.
• Hydraulic machines with screw or screw type.
• Vibrating pump.
• Mechanisms with a vortex principle of operation.
Depending on the place where the pump is placed, there are surface and submersible versions.
Device selection
Submersible equipment
Such devices are located directly in the water column. But it should be located at a distance of 50-100 cm from the bottom. If you place it lower, there is a probable possibility of capturing bottom deposits, sand. And this creates a danger of device failure. This equipment has a number of indisputable advantages:
1. It is possible to pump out water from a great depth.
2. The operation of similar devices is accompanied by less noise. Therefore, they can be placed near the house.
But servicing and repairing such pumps is very difficult.
Vibrating and centrifugal well pump
They are used most often. Such popularity is not accidental at all and is due to the following circumstances:
• Devices have high productivity. Its indicators can reach 100 l/min.
• Can be used at great depth.
• It is allowed to pump water with impurities of small fractions.
The disadvantage is that such devices do not like to idle. Therefore, before starting it, it needs to be filled with water. Must have such devices electromagnetic valve. The principle of operation is based on rotation inside the wheel, on which the vanes are located. Their rotation leads to the formation of a pressure zone. The middle of the chamber is filled with rarefied air. As a result, water flows in. For this purpose, the device is equipped with an inlet pipe.
The vibrating pump has no rotating elements, which makes it easier to work. As a result, the useful life is extended. The main elements are represented by a coil and a core. An electromagnetic field is created in which the elements make translational movements. These movements are transmitted to the piston, which ensures liquid suction.
The price of such pumps is low, and their construction is not complicated. Along with advantages, there are also disadvantages. The devices have low power. Therefore, they cannot be used for large depths. Vibrating pumps are characterized by low productivity. In addition, if the walls of the well are not protected, the operation of the vibrating pump can destroy them.
A surface pump differs from submersible equipment not only in terms of where it is located, but also in many other parameters.
Surface-type equipment
For a surface pump, you can build a special platform that will be at the water level. Such devices are usually used in cases of shallow wells. As a rule, it is no more than 8-9 m. At a greater depth, it is necessary to use the second type of pump or one that has an ejector.
In the surface versions, the centrifugal type is mainly used. The main element is a wheel on which there are paddles. Water is pumped out using a hose or pipe lowered into the mine. Similar pumps have the following advantages:
1. Ego is very easy to maintain and repair technically. The operation itself does not represent anything complicated.
2. Easy accessibility to the device is ensured, which allows you to carefully monitor its operation.
Such a device is not without disadvantages:
• The work is accompanied by a significant level of noise.
• The equipment is exposed to rain, snow, and other natural phenomena.
In summer, such pumps are covered with a light improvised canopy to protect against rain. But if such a pump is used around the clock, it should be in a warm room. It is possible to build a special caisson, which is located below the freezing point of the soil. When servicing, the pump is located at home.
