Abstract :
This project work details the design,
manufacture, and testing of a centrifugal pump. The
centrifugal pump is driven by an electric motor, which is
also linked to a tachometer, a variable frequency drive
and a wattmeter, which measure the speed of the motor
shafts and the electrical power of the pump, respectively.
The driven centrifugal pump pulls fluid (water) from a
sump reservoir and transfers it to a tank through a flow
control valve. We were able to conduct the experiments
required to completely describe a centrifugal pump using
the demonstration unit. The correlations between the
different parameters, such as head (H), efficiency (η),
rotational speed (ω), and input power (Pi), and the flow
rate (Q), were also generated in tabular and graphical
form. The experimental findings acquired at the
conclusion of this study demonstrate that the tested pump
can achieve a head (Hₘₐₓ) of 35m, a volumetric discharge
(Qₘₐₓ) of 35l/min, and a speed of 2850 rpm with an input
power of 0.5HP. The pump's performance was reported
to be very smooth, with minimal vibration and noise
levels on both the pump and the motor, ensuring the
pump's reliability in service.
