Common failures & inspection points

Valve integrity and tightness of compression stages compromised

Inspect all inlet and outlet valves for wear, contamination or damage; test seating surfaces with compressed air; check for abnormal noise or vibration during operation

Oil pressure and lubrication system failure in bearing surfaces

Check oil pressure at all bearing points (minimum 2 bar), observe oil contamination and colour (should be clear/amber), check oil level and drain line for blockage

Cooling system blockage, corrosion, or calcification reducing efficiency

For air-cooled: check fan blade for contamination/corrosion, monitor cooling fins for blockages; for water-cooled: inspect pipes for scale deposits/corrosion (especially saltwater), check shaft cooling inserts for wear

Piston, cylinder, or seal component wear reducing compression performance

Measure piston ring wear (max. clearance 0.5 mm), inspect cylinder bore for scratches/roughness (surface finish Ra<0.4 µm), check sealing rings for cracks/deformation

Safety valve or pressure gauge calibration drift or malfunction

Test safety valves per stage with calibrated pressure gauge under load (should open at specified pressure values), compare pressure gauges with reference standard, perform leak test
