MAB-205-MDO-Purifier

Typowe problemy

• Bowl imbalance or vibration from disc stack fouling or incorrect reassembly
• Sludge discharge malfunction - partial ejection or water seal problems
• Top/bottom bearing wear causing noise and vibration
• Friction clutch or gear coupling wear affecting start-up ramp time
• Incorrect gravity disc/dam ring selection for the current fuel or oil density
• Sliding bowl bottom O-ring wear causing internal leakage
• Feed or discharge valve fouling

Lista kontrolna przeglądu

• Vibration monitoring trend to detect bowl imbalance
• Bowl disassembly, cleaning and disc stack inspection at scheduled overhaul
• Bearing condition check/replacement at the manufacturer-specified interval
• Sliding bowl bottom seal (O-ring/gasket) inspection
• Water seal and seal-water supply check
• Discharge sequence and de-sludging interval verification
• Gravity disc/dam ring check against current fuel or lube oil density
• Motor current draw and motor bearing check
• Frame and foundation bolt tightness check

Krytyczne części zamienne

• Top and bottom bearing sets
• Sliding bowl bottom O-ring/seal kit
• Disc stack gasket/seal kit
• Friction clutch pads or gear coupling elements
• Gravity disc set covering the expected density range
• Water seal ring

Bezpieczeństwo

• High bowl rotational speed - never open the bowl casing before the rotor is confirmed fully stopped
• Hot oil/fuel surfaces and piping around the unit
• Incorrect bowl reassembly can cause violent imbalance and structural failure
• Pressurized water seal supply system

Przegląd klasyfikacyjny

Fuel oil purifiers/separators are usually within the Continuous Survey Machinery scope on classed vessels; class looks for evidence of bearing/overhaul intervals followed per the maker's manual, vibration monitoring records, and the correct disc/gravity ring configuration for the fuel currently in use.

Szacowana trwałość: Disc-stack separators of this size and duty are commonly kept in service 15-20+ years, with the bowl and frame as the long-life components while bearings, seals and gaskets are wear items replaced on a fixed schedule.
