The pump is managed in several ways, including:
1-Electric motor
2- Steam turbines
3-Gas turbines
4-Internal combustion engines
1.Electric motor:
It has two main types with multiple current and direct
current motor and the two types work with a conversionElectrical
energy into mechanical energy by generating a magnetic
field between the stator and rotor motor windings.
The DC electric motor is small and therefore found
in fuel-oil-lubricant-cooling water pumps.
As for the electric current with multiple current,
it is the most common because of the diversity
of its forms and the diversity of power generated from it.
2- Steam turbines:It is an engine that generates
the thermal energy in the steam into mechanical
energyRepresented by the rotation of the shaft of the
turbine after applying steam to the blades of the turbine fans.
Steam turbines may be used to produce the mechanica
l power necessary to manage pumps when the steam
source is available for the following reasons:
A – Because it is characterized by high efficiency
compared to the electric motor and engines for
internal combustion and gas turbines.
B- Management of pumps of utmost importance
in petroleum refining companies in order to ensure
that there is no sudden stoppage And often there
is a pair of pumps, one of which is driven by
an electric motor, and this isThe main pump and
the other with a steam turbine and this is the backup pump.
C- Wide variety of speeds by controlling the amount
of steam entering the soilBy means of a steam ruler
or a separate valve or valve on the steam design line.
D- The use of steam instead of electricity has become
possible in places where the emergence ofElectric
sparks and also reduced the incurrence of additional
insulation costs.The steam turbine can manage all types of pumps.
F- Ease of installation and maintenance and less vibration problems.
3- Internal combustion engines (diesel – gas – gasoline):
When fuel is available, internal combustion engines are
used to manage the pumps in1- Irrigation works.2- Fire
fighting.3- High pressure pumps needed to clean heat
exchanger pipes.4- Large pumps that need high mechanical capacity
.4- Gas turbines:It is a machine that draws very large amounts
of atmospheric air by means of a multistage axial compressor
that compresses this airCompressed with gas in the combustion
chamber to produce gases from the fire that have very high
energy due to the highIts temperature and pressure,
and these gases go to the turbines to move them
at high speed and very high mechanical ability.
Gas turbines are characterized by the diversity
of their capacity and speed to manage pumps in
applications such asPumping crude oil into
pipes and water pumping stations in oil
wellsFluid pumping: Gas turbines can be
used to power pumps used to pump liquidsIn
applications such as thermal power plants and water treatment plants.
Oil and gas extraction: In the oil and gas industry,
gas turbines can be used to powerPumps
used to pump oil and gas from wells to surfaces.
Air cooling: Gas turbines can be used to power
cooling fans in air conditioning and cooling systems of buildings.
Gas stirring: in applications such as Brian’s cycle-based power plants,
Gas turbines can move gas between different parts to achieve an improvement in performance.
