Analysis of separator “failures”
More than 5 mm of oil in the internal base / bowl of the separator is due to a fault in scavenging. Determine cause of fault, rectify and re-use separator if not damaged, blocked or aged.
Under normal circumstances the wet band, more easily seen on the outer surface of the white filter media than the inner, which is wet with oil being indicated by a golden yellow colour – if not dyed mineral oil is in use – should not extend more than 25 to 50 mm form the separator base. If the wet band, on examination, extends from the base to the top (flange) or almost to the top then the separator is saturated. Determine cause of fault, rectify and re-use separator if not damaged, blocked or aged. When starting a compressor with a saturated separator an oil mist will be carried over (can be seen if blown to atmosphere) for a few minutes whilst the separator rids itself of excess oil. During this period the separator differential pressure will lower. If the differential pressure does not reduce to 0.2 to 0.3 bar within 10 minutes whilst the compressor is on load then the separator should be replaced.
Determine compressor / compressor room / ventilation / pollutant fault and rectify, then change oil, oil filter and separator.
Check sealing and integrity of air filter and replace same. Check environmental conditions and rectify where possible. If compressor sounds different to the ear than normal when either n or off load or both then it indicates airend and / or gear box wear and imminent failure. Compare monitored dB bearing readings to history / maximum allowed. Rectify cause of fault. Do not re-use separator.
Being normal at or beyond compressor manufacturer’s recommended change interval; this may be as low as 3000 hours for hot running compressors with small (mineral) oil fill. For cool running compressors or those with a large (mineral) oil fill, this may be 6000 to 8000 hours. For the many reasons of high differential pressure prior to normal expected life refer to Section 1.0 above. Fine dust particles and extended molecular strings causing blockage do not generally discolour the outer filter media.
Determine cause for high differential pressure which leads to a separator collapsing; compressor mechanical fault – minimum pressure valve or other cause, operational fault – opening or closing too rapidly of discharge air valve. Determine mechanical or operational fault and rectify. 2.7 Collapsed separator – limited discolouration Determine cause for high differential pressure which leads to a separator collapsing. Possible causes: build up of shellac, dirt or other particles, mixed oils.
Determine cause for high differential pressure which leads to a separator collapsing. Possible causes: incorrect oil, sludge formation, dirt, damaged or poor fit of air filter.
Either implosion or explosion; Study soot colour and grain: soot fined grained and grayish indicated an explosion and usually accompanied by mechanical damage to components between and inclusive of the air-end housing and separator tank, soot course grained and blackish indicates a flash fire. Determine cause, repair / overhaul compressor, change separator, air and oil filter and oil.
