What are the different uses of pumps?
Submersible pumps are a great option when it comes to transferring liquid from a big water source. These pumps operate by being placed underwater and pushing water up to the surface, as opposed to traditional water pumps that are situated on land and pull water up. Not only can submersible pumps produce excellent outcomes, but they also consume less energy compared to other ways of bringing water up to the surface.
Submersible pumps are exclusively designed to work underwater, which limits their usage to deep water sources. However, if you have access to such sources, they prove to be the perfect pump for your needs. The article will discuss the various common uses of submersible pumps.
How Does a Submersible Pump Work?
The pump operates by transforming rotational energy into kinetic energy, and subsequently, into pressure energy, enabling it to move water from underground to the surface. Alternatively, the water can be propelled into the pump through a diffuser, where it is driven by the impeller’s rotation.
Multi-level centrifugal pumps are submersible pumps positioned in a vertical orientation. In these pumps, the impeller increases the fluid’s kinetic energy, which is then transformed into pressure energy in the diffuser. This principle is common to both mixed flow and radial pumps. Hydraulic submersible pumps, on the other hand, use a hydraulic motor in place of an electric motor. Closed-cycle pumps maintain a separation between the power liquid and the generated liquid, while open-cycle pumps mix the power flow with the generated fluid, with surface isolation.
A mechanical coupling connects the pump’s shaft to the protector or gas separator located at the bottom of the pump. A screen at the pump’s inlet draws in the liquid, which is then lifted by the pump’s stages. Bushings that run the length of the shaft provide radial support, while thrust bearings handle axial forces. Protectors’ thrust bearings are designed to operate under maximum axial loads. Various types of submersible pumps are available, including those with a steel screw as the active component. This screw enables the pump to operate even in the presence of extremely high levels of impurities.
Submersible Pump Uses:
Irrigation
Submersible pumps play a crucial role in providing water to crops, thereby sustaining our food supply in the long term. These pumps are tasked with moving large quantities of water from one place to another, making their job extremely challenging and important. The two most common submersible pump configurations used for irrigation are deep-well submersible pumps and vertical turbine pumps. The most significant difference between the two is the motor’s location. Vertical turbine pumps, which are installed above ground, feature an engine connected to the pump itself via a line shaft. On the other hand, deep-well submersible pumps have a more complicated design that includes a submerged motor capable of handling high pressure.
Pumping From Borewells and Wells
If your household relies on water from a well or borehole, you may need to transfer the water to storage tanks. In such cases, submersible pumps are the ideal choice, as they are highly efficient at pumping water from great depths and consume minimal power.
Construction and Building
Water pumps are essential on most construction sites for removing wastewater. Typically, a single-phase pump of up to 1.5kW and a head of up to 21 meters can handle the low flow rate. Contractor pumps are specially designed to be robust, adaptable to site conditions, and capable of moving viscous liquids. However, it’s crucial to consider the aggressive media that will be pumped on the construction site when selecting materials that can withstand such conditions.
Industrial Application
Submersible pumps that are portable, lightweight, and easy to handle are well-suited for firefighting. They can also be invaluable for extracting water from deep or twisted wells. In addition, submersible pumps are an excellent choice for draining flooded areas, as they can withstand being submerged without being damaged.
When it is necessary to reduce noise levels, submersible pumps are an excellent choice for installing booster pumps. In locations where there is limited floor space available for the installation of water pumps, submersible pumps are beneficial due to their compact size and ease of adjustment.
Oil Extraction
Submersible pumps can be used to pump a variety of fluids, and their operating principles are generally similar. They are widely used in the oil industry due to their ability to operate against gravity and handle fluids with varying viscosities, with only minor modifications. Unlike pumps designed specifically for water, those used to extract oil must be able to withstand a wide range of temperature, viscosity, and depth variations. Electrical submersible pumping systems are constructed to ensure maximum durability and productivity even at depths of 4000 feet or more, which is a standard operating depth.
Drainage of unwanted bodies of water
If you have a pond or other body of water on your property that you want to get rid of, submersible pumps are a great option. They can also be used to pump out water from flooded basements and other areas.
Other Applications
The following are some possible Submersible Pump Uses:
- Submersible pumps have a wide range of potential applications, including but not limited to drilling deep wells, handling slurry and wastewater, managing saltwater in water and oil wells, treating dirt, fighting fires, and dehydrating mines.
- Submersible pumps have been utilized for mine dewatering and rescue operations, except for the Navy.
- Sewage, industrial, and drainage applications commonly utilize single-stage pumps.
- Multistage pumps are frequently used in municipal, engineering, and commercial applications.
