Well pumps

The main characteristics of

pumps The use of pumps greatly facilitates the supply of water and saves a lot of time and energy. This is especially important when a large amount of water is needed for certain purposes. To raise water, various types of pump units are used from different areas of human activity. However, there are well pumps, which are designed specifically for working with wells and other deep reservoirs. It is about them that will be discussed in the article.

The various pump units that are used in water wells have a number of specific characteristics that need to be considered when choosing:

The distance to which water is to be supplied.
Pump capacity( the amount of water per unit of time that a device can perform).
Hydraulic accumulator capacity.
Required water head.

Also, when choosing a pump unit, it is worth paying attention to the well indicators, which represent the following parameters:

Depth, on which there is a mirror of water.

Bottom well performance( a value that characterizes the possible volume of water that will flow).
Degree of contamination of water.

After taking into account all the above mentioned parameters, it is possible to select the required pump with certain performance characteristics.

Characteristics of various types of well pumps

Pump units are divided into a number of types:

Submersible.
Superficial.

In turn, submersible devices for pumping water are divided into such subtypes:

Centrifugal.
Drainage.
Vibrating.

Next, the characteristics of each of the types and subtypes will be given.

Sump pumps submersible centrifugal

This kind of pumping units is a device of cylindrical shape, made of stainless steel, under the cover of which is the engine. The main working elements of this device are:

The engine, which operates on the principle of centrifugal force in a dense shell.
A device that directs water upwards, which is called an impeller.

To ensure trouble-free operation, the pump must always be submerged in water. To ensure that the hydraulic pump does not choose all the water in the well, floats or automatic regulators are used.

The minus of work of this type of pump unit is a large amount of oil used by the engine for operation. In case of depressurization, the oil gets to the outside and forms a film on the water, which is then very difficult to remove.

There are several ways to get rid of the oil stain on the surface. The first way is to collect water with the help of a "baby", in which this device is lowered several times to the surface, after which all the oil is collected in it. The second way is the use of special chemicals that are placed in water and dissolve the oil film.

Submersible drainage pumps

Submersible drainage pump units are used for purposes different from these in the case of centrifugal hydraulic pumps. This type of device is used mainly for pumping out clogged water from various cavities and rooms. It can be dirty wells, cellars and even drainage pits. With the help of this type of pump it is possible to pump out large volumes of water in a short period of time. Devices of this type deliver water to a small height and create a small head, but this is consistent with the goals set for them.

Submersible vibratory vibratory pumps

Submersible vibratory pump units are used by truckers because of their ease of operation. Among the advantages can be identified:

High water delivery height.
High level of reliability.
Affordable price.

The downside of this pump is the fact that it can not be used in wells on quicksands, since this type of hydraulic pump can fill water during operation.
