Common failures & inspection points
Visually inspect bowl interior through inspection ports and observe vibration levels during operation; check motor amperage increase (typically 10-15% above baseline indicates excess sludge)
Monitor gearbox operation for abnormal sounds and vibration; inspect vertical shaft support bearings (radial springs and ball bearing under thrust); verify spring integrity
Check sludge discharge side via peephole; inspect sight glass of drain line for water presence; never discharge while separator is vibrating; verify butterfly valve opening in sludge outlet
Verify all foundation mounting bolts are fully tightened; check damper springs for corrosion, erosion, or deformation; test vibration isolation system at startup and during operation
Inspect pilot valve mechanism for deposits or scoring; verify bowl assembly O-rings and seals for hardening or leakage; confirm rotating bowl speed reaches rated RPM within specified time (5-10 minutes depending on model size)
