Lube Oil Carbonisation
Abstract
Carbonized particles can get deposited in housing oil seal clearances causing a partial rub like phenomenon. Friction caused due to reduced clearances because of accumulation of carbonized particles leads to shaft thermal bow inducing 1X vibration. When the accumulated particles are abraded due to increase in vibration, the clearance opens up which reduces the thermal bow causing the vibration levels to drop to normal levels and this cycle repeats.This presentation outlines a case where a similar phenomenon wasobserved causing the unit to trip after a few hours of operation. Successful diagnosis was carried out using vibration data which is presented in this case study.
