Cavitation phenomenon is basically a
process formation of bubbles of a flowing liquid in a
region where the pressure of the liquid falls below its
vapour pressure and it is the most challenging fluid
flow abnormalities leading to detrimental effects on
both the centrifugal pump discharge characteristics as
well as physical characteristics. In this low pressure
zones are the first victims of cavitation. Due to
cavitation pitting of impeller occurs and wear of
internal walls of pumps occurs due to which there is
creation of vibrations and noize are there. Due to this
there is bad performance of centrifugal pump is there.
Firstly, description of the centrifugal pump with its
various parts are described after that pump
characteristics and its important parameters are
presented and discussed.
Passive discharge (flow rate) control methods are
utilized for improvement of flow rate and mechanical
and volumetric and overall efficiency of the pump.
Mechanical engineers is considering an important
phenomenon which is known as Cavitation due to
which there is decrease in centrifugal pump
performance. There is also effect on head of the pump
which is getting reduced due to cavitation
phenomenon. In present experimental investigation
the cavitation phenomenon is studied by starting and
running the pump at various discharges and cavitating
conditions of the centrifugal pump. Passive discharge
(flow rate) control is realized using three different
impeller blade leading edge angles namely 9.5 degrees,
16.5 degrees .and 22.5 degrees for reduction in the
cavitation and increase the of the centrifugal pump
performance at different applications namely,
domestic, industrial applications of the centrifugal
pump.
