Common failures & inspection points
Visual inspection of oil through sight glass monthly; check for discoloration, sludge, water contamination; replace per manufacturer schedule (typically 500-1000 operating hours)
Record operating pressures and discharge temperatures daily; verify safety valve opens at correct pressure setting (typically 35-40 bar for marine units); ensure outlet air temperature stays within 10-30°C above ambient
Visual inspection of all pneumatic hoses, fittings, and water cooling lines weekly for moisture, salt corrosion, or seepage; apply soapy water test to detect micro-leaks; inspect for salt crystallization typical of marine environment
Listen for unusual bearing noise or grinding sounds during operation; measure vibration levels (marine units typically max 40 mm/s RMS); inspect valve plates, piston rings, and cylinder walls for wear; perform visual exterior corrosion assessment
For water-cooled units: verify cooling water pressure (0.5-3.0 bar typical); check for salt deposits or algae in cooling passages; ensure heat exchanger not fouled; inspect cooling water intake filters monthly; verify outlet temperature within specification
