Common failures & inspection points
Impeller condition: inspect cast aluminium impeller blades for corrosion, erosion, deposits, and mechanical damage; check blade angle and balance
Motor and bearings: check Class F motor insulation resistance (Megger test), bearing condition (temperature, vibration, noise), and IP55 seal integrity
Casing and corrosion protection: inspect hot-dip galvanised sheet steel casing for corrosion breakthrough, paint delamination, or mechanical damage; re-treat as required
Inspection hatch: verify hatch seal and locking mechanism are intact and watertight; check hinge and fastener condition
Electrical connections and terminals: inspect terminal box for moisture ingress, verify cable gland integrity, check connection tightness and insulation
Vibration and noise levels: measure vibration amplitude and compare to baseline; unusual noise may indicate bearing wear, imbalance, or loose fasteners
Airflow performance: verify actual airflow (m3/h) against commissioning values using a flow measurement instrument; excessive deviation indicates fouling or mechanical fault
Lubrication: check and replenish bearing grease per manufacturer schedule; verify lubricant type is compatible with marine environment and operating temperature range
