Machine Condition Assessment of Agitator Gearbox Case Study
Problem
A petrochemical plant identified metal particles and debris in the oil pump of a vertical agitator gearbox. KHE was contracted to evaluate the casing vibration of the unit to determine if bearing or gear damage was evident.
Solution
Three-axis vibration measurements were conducted to assess the mechanical condition of the gearbox. Evaluation of vibration velocity spectra and acceleration time waveforms did not identify evidence of bearing or gear damage.
Results
A major overhaul of the gearbox was postponed.
