MAB-209

Typowe problemy

• Bowl vibration from incomplete sludge discharge or a fouled disc stack
• Sliding bowl bottom / operating slide wear causing seal water leakage or incomplete discharge
• Friction/clutch drive wear (where a friction gear drive is fitted) reducing run-up performance
• Seal ring and O-ring degradation from repeated heat cycling
• Bowl spindle or gear unit bearing wear causing noise or vibration
• Reduced separation efficiency from a fouled or worn disc stack
• Sludge or water discharge port blockage

Lista kontrolna przeglądu

• Check bowl vibration level while running
• Inspect sliding bowl bottom seal rings and O-rings at every bowl opening
• Check the disc stack for fouling, distortion or corrosion
• Verify the sludge/water discharge sequence completes fully each cycle
• Check gear unit or friction coupling oil level and condition
• Inspect bowl spindle bearings for play or abnormal noise
• Verify operating water and seal water supply pressure and flow
• Check bowl-locked and cover interlocks operate correctly before starting

Typowe granice zużycia

Zakresy są typowe dla tej klasy konstrukcyjnej. Decydujące są zawsze dokumenty producenta dla danego numeru seryjnego.

Krytyczne części zamienne

• Bowl gasket / O-ring kit
• Sliding bowl bottom seal rings
• Bowl spindle bearing set
• Friction pads/clutch lining (if a friction drive is fitted)
• Spare disc stack for exchange during overhaul
• Seal water solenoid valve

Bezpieczeństwo

• The high-speed rotating bowl stores significant energy - never open the casing until the bowl has fully stopped and is confirmed locked
• Hot oil/fuel under pressure at inlet and outlet connections
• Correct bowl balance is safety-critical; an incorrectly assembled bowl can fail catastrophically at operating speed
• Follow the maker's specified torque sequence exactly when closing the bowl - incorrect tightening is a recognised cause of bowl-top failure

Przegląd klasyfikacyjny

Fuel oil and lube oil separators are typically covered under Continuous Survey Machinery. Class looks for evidence of overhaul per the maker's PMS, correct bowl assembly/torque records, and confirmation that casing containment and safety interlocks are intact, given the stored rotational energy in the bowl during operation.

Szacowana trwałość: Disc-stack separators of this capacity class typically run 8,000-16,000 hours between major bowl/bearing overhauls, with the bowl and drive unit remaining in service for the vessel's life subject to periodic overhaul
