DETEKSI KERUSAKAN BANTALAN GELINDING PADA POMPA SENTRIFUGAL DENGAN ANALISIS SINYAL GETARAN
Abstract: The aim of the
research was to detect the fault of rolling bearing in a centrifugal pump by
vibration signal analysis. The investigation was focused on the
frequencies of the
bearing components, that
are: frequency of
outer race, inner race, ball, dan cage. The pump with power 5,5 Hp and
speed 1495 was used in
the experiment. The
vibration data was
obtain by piezeelectric accelerometer, and
a digital storage
osciloscope. The MATLAB
software then was used
to process the
data to get
signal spectrum. Analysis
of the signal spectrum gaves that good condition
rolling bearing have amplitude of 0,8 Volt. While, in defect ball bearings
there were increases of amplitude in ball bearing components harmonic
frequencies. The increase of amplitude were 1,2 Volt in 4 x Ball Pass Frequency
of Inner Race (BPFI), 1,66 Volt in 3 x Ball Pass Frequency oh Outer
Race (BPFO), and
2 Volt in
2 x Ball
Spin Frequency (BSF).
These increases of frequancies indicated the damage of the ball bearing
components.
