3.6.1 Compressor
General remarks about check list;
1. Check list for compressor only; all other components have to be maintained
according to their specific manuals (IMM and SIM).
2. All items of the list below marked “check“, have to be checked visually and
checked for proper working.
3. Some components have to be measured.
For measuring details refer to SIM.
4. Measuring means also that visual inspection is required.
5.
Visual inspections:
The visual inspections during maintenance are of importance; measurements
should be carried out at the moment that visually abnormalities are detected.
The result of the inspection determines whether one or more parts have to be
replaced. For more detailed information refer (SIM) and Installation and
Maintenance Manual (IMM).
6. Oil and oil return systems:
The quality of the oil effects the oil consumption and the life time of the
moving parts. For oil return systems or systems in which soluble oil is being
used, we advise to check (or have checked) the quality of the oil every 5000
hours and - if necessary - to renew the oil and/or filters. If there is no oil
analysis available, we advise to renew the oil. By regularly carrying out oil
analyses and registering them in a log, aberrations will be noticed in an early
stage, which may prevent or reduce resultant damage(s).
Note 1:
When renewing the oil, in the crankcase the oil in the oil separator and the oil
return or oil rectifier system (if fitted) has to be renewed.
Note 2:
Pre-lubricate the compressor before re-starting. Used or filtered oil should
NEVER be added to a compressor under any circumstance. Use only new oil
as selected from the Grasso oil table. Oil charging via the suction line of the
compressor is not allowed.
