Abstract—An impeller is a rotating component of a radiator pump, usually made of iron, steel,

bronze, brass, aluminum or plastic, which transfers power from the speed that drives the pump to the

fluid being pumped by accelerating the fluid outwards from the middle of rotation. The swiftness

achieved by the impeller transfers into stress when the external movement of the fluid is limited by

the pump outside. Impellers are usually undersized cylinders with an release inlet (called an eye) to

accept received fluid, vanes to shift forward the fluid radially. The Impellers modeling of the

impeller was done to design by using CATIA V5 R18 solid modeling software. It is future to design

a blower with plastics material, Analyze its strength and deformation using FEM software. In order

to calculate the effectiveness of plastics and metal blower and impeller using FEA (ANSYS). Modal

analysis is performed on PARA material impeller to find out the three different cases of rpm,

pressure and temperature.

Keywords— Impeller, fluid, Drive shaft, CATIA V5 R18, FEM (Ansys), PARA Material.

I. INTRODUCTION Centrifugal pumps, compressors, and blowers utilize various impeller designs that are an

essential component for bulk transport of fluids. Typically, a motor is used to spin a shaft that is

connected to a housed impeller, which draws fluid in along a rotating axis. The fluid is accelerated

and whirled radially and tangentially outward through the impeller vanes, where it exits through a

casing designed to decelerate the fluid velocity and increase fluid pressure. Centrifugal pumps are

susceptible to various modes of impeller failure including but not limited to inter granular corrosion,

erosion, cavitations, material defects. An impeller is a rotating component of a radiator pump,

usually made of iron, steel, bronze, brass, aluminum or plastic, which transfers energy from the

motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the

center of rotation. The velocity achieved by the impeller transfers into pressure when the outward

movement of the fluid is confined by the pump casing. Impellers are usually short cylinders with an

open inlet (called an eye) to accept incoming fluid, vanes to push the fluid radially, and a splined,

keyed or threaded bore to accept a drive-shaft. The impeller made out of cast material in many cases

may be called rotor, also. It is cheaper to cast the radial impeller right in the support it is fitted on,

which is put in motion by the gearbox from an electric motor, combustion engine or by steam driven

turbine. The rotor usually names both the spindle and the impeller when they are mounted by bolts.

II. PARA MATERIAL ( polyarylamide)

PARA (polyarylamide) provides a unique combination of strength and aesthetics,

making it ideal for complex parts that require both overall strength and a smooth, beautiful surface. It

compounds typically contain 50-60% glass fiber reinforcement, giving them remarkable strength and

rigidity. What makes them unique is that even with high glass loadings, the smooth, resin-rich

surface delivers a high-gloss, glass-free finish that’s ideal for painting, metallization or producing a

naturally reflective shell.

3.1 High flow into thin walls In addition, PARA is an extremely high-flow resin so it can readily fill walls as thin as 0.5

mm, even with glass loadings as high as 60%.

3.2 Excellent Surface Finish

Superb, resin-rich surface provides a highly polished appearance, even with high glass fiber

content .The tensile and flexural strength of compounds are similar to many cast metals and alloys at

ambient temperature. It (60% glass fiber) exhibits typical values of 280 Mpa and 400 Mpa

respectively at 23°C (73°F).

V. CALCULATION

Temperature at 50°C

Factor of safety = Yield strength/von mises stress

=280 mpa/56.7746 mpa, =4.93

Temperature at70°C

Factor of safety = Yield strength/von mises stress

=280/113.677 =2.46

Temperature at 90°C

Factor of safety = Yield strength/von mises stress

=280/170.58 =1.64

VI. CONCLUSION: If the three cases of PARA material using to check various temperature at the Vonmises stress

and total deformation compared at the high temperature 90°C factor of safety is better. By using

polyarylamide impeller corrosion will be reduced. Compare to aluminium plastics less weight and less

cost, Easy any shape , Life compare to other material is high
