SPM is not vibration
analysis. SPM is better than vibration analysis. Shock Pulse
Method involves using sophisticated computer technology and
programming of all individual rolling elements to determine lube
film thickness, alignment, stress, wear and damage. This is
accomplished by first gathering as much information about the test
subject as possible. An individual testing program is written for
each specific test point. Using a handheld or permanently mounted
transducer, signals and readings are taken while the point is
rotating. This is done directly through the bearing housing or
eccentric. External interference is bled out, so that only the
test point is being monitored. The external noises may include:
eccentric or housing wear, DC brush arching, coupling, gearing or
gearbox wear, shaft or journal damage, siphon tubes, machine
parallel issues, machine or motor alignment issues, low lube
levels, lube contamination and much more.
The collected readings
(up to 1500 per second) are downloaded into the analysis program
and plotted for life span, operating status and performance.
Based on these findings
PCT generates a digital report for each defect uncovered and
issues that report to the maintenance team at the end of the
testing day. There is no waiting for a mailed report when critical
issues may be affecting your production.
