A submersible pump, also known as an electric submersible pump, is a centrifugal pump that can be completely submerged in water. The motor is sealed and firmly fixed to the pump body.
Submersible drainage pumps pump water by converting rotational energy from mobile energy to surface pressure. This is done by injecting water into the pump: first, it pushes the water impeller into the diffuser. From there, it reaches the level.
The most important advantage of a submersible pump is that it does not need to be refilled because it is submerged in liquid. Submersible pumps are also very efficient because they don’t require much energy to transfer water to the pump. The water pressure directs the water into the submersible pump, which stores a large amount of the pump.
When installing submersible pumps, many workplaces have areas that are considered “confined spaces” because they make it difficult for workers to enter, work, and exit. Access to these areas requires trained, equipped, and authorized personnel able to safely perform the required activities.
Development of submersible pumps
Submersible pumps were originally made in Europe and became more common in the United States in the 1950s. Some people initially doubted the reliability of the underwater models, believing that they would be difficult to usefully. However, the first models were successful, and the pumps became popular in the 1960s. At the same time, the pump is equipped with guide rails to disconnect the pump in case of repair. Due to the benefits of using submersible pumps, more and more companies are growing. They are now an integral part of many modern pumping stations and various other applications.
Application of the submersible pump
A submersible pump is available in different sizes for different applications. They can be installed as a unit or as a dual system. In industrial applications, installing two pumps is often the preferred option because if one of the units fails, it will create some redundancy. Reduces the damage of a bomb. It can provide more capacity if needed.
One of the main advantages of the submersible pump is that it can be buried without any problem. Therefore, they are installed in different environments, including:
- Deep wells
- Areas prone to flooding
- Where traditional pump motors can be damaged by contaminated water
- Necessary for silent pump settings
- Areas with limited space
- Agricultural applications
The submersible sump pump can be used in series with the pipeline to increase the flow. At certain points in the pipeline, they can be installed horizontally instead of vertically. They are very suitable for use in this type of environment because they are virtually silent in operation, and the motor and electrical components are connected to prevent liquid damage.
Although submersible pumps have a wide range of applications, they are not a good choice in some cases. This includes:
Areas where the liquid temperature is too high
– If the environment is particularly corrosive
– Where there are many abrasive elements
The liquid contains large diameter solids or contaminants.
Controlling of Submersible Pump
Each specific system is designed to suit a wide range of applications. The control system directly manages the fluid level at predetermined parameters and starts or stops the submersible pump when the fluid level reaches the predetermined fluid level. There are usually three different pump control devices that can turn the pump on or off and sound the alarm if the liquid exceeds the specified level.
In a two-pump system, control is usually intermittent between two pumps. This multi-pump system also has a clear function, which is used to start the second pump when one pump fails to match the flow rate or the first pump fails.
The development of a submersible pump has made it a very safe device to use. Once installed, this pump is reliable and can be used for years, which is why submersible pumps have become the first choice for more domestic and industrial applications.
