Fluid and Vibration Monitoring
Ingersoll–Rand recommends incorporating predictive
maintenance, specifically the use of oil and vibration
analysis, into all Preventative Maintenance programs.
Predictive Maintenance is designed to increase system
reliability and prevent costly downtime. Through the
use of sophisticated diagnostic tools, including fluid,
vibration, and optional air analysis, IR Certified Service
Technicians can identify and correct potential problems
BEFORE they can cause expensive unscheduled
downtime.
How does predictive analysis work? By establishing an
initial baseline for normal operation, and then regularly
monitoring fluid and vibration conditions, any sudden
deviation or significant increase from this baseline can
be identified and investigated to pinpoint the cause.
More quickly diagnosing potential problems can directly
save money by preventing costly failures and reducing
or eliminating downtime. In addition, regular condition
monitoring also helps to maximize the time between
expensive preventative maintenance intervals, such as
component rebuilds and oil changes.
Oil Sampling Procedure
With unit at sump oil temperature of 130 – 140
_
F, stop
the compressor. Wait 5 minutes, or sufficient time until
oil in sight glass becomes clear, and any entrained air
bubbles in the oil dissipate.
Remove oil fill cap from oil fill tube. Using oil sample
pump kit, install a new hose on the pump. Insert the
hose into the fill tube, and push the sample tube all the
way to the bottom of the oil sump. You will feel the hose
hit the the bottom of the sump. Once the bottom is felt,
pull the hose up about one inch. This prevents a sample
from gathering any sediment that may be on the bottom
of the sump. Extract the sample.
Remove the hose, remove the sample cup cap the cup,
and reinstall the oil cap. Label and process the sample..
