Equipment Condition Assessment for Industrial Blowers

We assess industrial blowers through a protocol that combines non-intrusive monitoring with clearance measurement. Non-intrusive assessment includes vibration measurement at all bearing locations and the timing gear housing with spectral analysis for gear mesh and bearing defect frequencies, discharge and casing temperature measurement, discharge pressure and flow assessment (where instrumentation permits), inlet filter differential pressure, and external leak inspection. Clearance assessment (requiring access) includes lobe-to-casing clearance measurement at drive end and non-drive end (top, bottom, and sides), lobe-to-lobe clearance measurement, timing gear backlash measurement with comparison to OEM specifications, and bearing endplay or radial clearance measurement where accessible. Visual assessment includes rotor surface condition (scoring, erosion, coating condition), casing internal surface condition, timing gear tooth condition (pitting, wear pattern, contact pattern), and seal condition. Each blower receives condition grades for rotors, timing gears, bearings, and seals, with clearance values compared to OEM specifications and remaining margin calculated. Assessment reports include recommendations for continued operation with monitoring, planned overhaul scheduling, or immediate intervention based on clearance margin and trending.
