Significance of
Submersible Pumps
As the name signifies, Submersible
Pumps are made to be submersed within a fluid of large volume. These Pumps find
wide application in sectors like agriculture, production of oil and
natural gas, petroleum refining, petrochemicals, power generation,
domestic and household utilities, etc,.
Usually submersible pumps are
classified in two stages viz. Single Stage Pump and Multiple stage
Pump. Actually, these are used to lift or pump-up moderate to high
volume of fluid. These pumps are self priming which do the air
sucking before pumping of liquid and work while being fully submerged
or by placing on a dry area.
Electrical Submersible Pump is
constructed by using five main elements which are Multistage
Centrifugal Pump, 3-Phase Induction Motor, Seal Chamber Section,
Power Cable and Surface Controls and and it is designed in such a way
that it doesn't comes in contact with the
fluid it is pumping hence, no risk of short circuit. The
operation of Submersible Pump is completely based on the principle of
force and pressure. When the impeller rotates at the high speed, it
exerts the kinetic energy which is then sent to the diffuser where
this kinetic energy gets converted into pressure. This pressure
pushes the fluid to enter into the pipe and then drained out through
the outlet of the pump.
What are the Types of
Submersible Pumps?
There are numerous applications for
which an electrical submersible pump can be used like in water wells,
mines and ships. Many other types of Submersible Pumps are also there
for different applications. These are listed below:
- Bladder Pump
- Grinder Submersible Pump
- Well Submersible Pump
- Fountain Pump
- Submersible Utility Pump
- Solid Handling Submersible Pump
- Dry Pit Submersible Pump
Bladder Submersible Pump : The
operation of this type of pump depends on the compressed air which
usually acts as the force on the water to push out through the outlet
of the submersible pump. This pump is generally utilized by the
Municipalities, Oil refineries & allied Industries and the
Environmental Protection Agencies.
Fountain Pump : This type of
Submersible Pump used to produce fountains and available from small
size to large size. Fountain Pumps continuously recycle the water and
shoot the water up to the desired height, depending upon the size of
capacity of pump.
Grinder Submersible Pump : These
type of Pumps are used for processing the waste water by grinding and
reducing the sewage particles. Grinder Submersible Pump is generally
used in waste water plant.
Solid Handling Submersible Pump :
These are used for handling the solid waste material. Solid Handling
Submersible Pump are available in large variety for different
application in different industry segments.
Applications of
Submersible Pumps
Waste-Water
Systems
Submersible pumps are utilized within
the waste-water treatment plant in circumstances where gravity stream
is inconceivable. Rough soil conditions, a high water table, or long
pipe going through sloping zones are all examples of situations that
block gravity. For such cases, submersible pumps are equipped with
evacuation bowls which gathers the waste water and pumps up to the
higher height.
In
Fire and Rescue Services
Submersible pumps are utilized to pump
out water to a base profundity of 15 cms or from open water source to
supply the water where incident has taken place.
Mining
Electrical submersible pumps for the
mining business are not the same as those utilized for new water or
petroleum concerns. Downhole conditions in respect to mines are
extreme because that mine water is acidic and conveys suspended
solids. Therefore, to drain out that acidic fluid, special
submersible pumps are used.
Navy
Submersible pumps are utilized by the
Navy and Coast Guard to drain out the water from the flooded region
into the sea or ocean.
There are numerous applications of
Submersible Pumps from the simplest to complex use.
Things to Remember
Before Selecting Submersible Pumps
There are many things which should be
considered before choosing the pump as selecting the right pump is
fundamental in enhancing the accomplishment of the system. These
points are:
- Pay attention to the type of pump and its application
- Maximum discharge flow
- Maximum discharge pressure of pump
- Outlet connections of submersible pump
- Horsepower of the pump
- Explosion proof
