Abstract

Journal Bearings are vastly used in major industries such as power generation, oil and gas production, refineries, and the like. Thus, much investigation and study has taken place for more effective maintenance and fault detection of these bearings. An effective method in maintenance for these bearings is Root Cause Analysis (RCA) that tools like FMEA and FTA are used in it. In this paper, initially meanwhile investigation of journal bearing failures prioritizing of them have been down by using FMEA and FTA. For this purpose, expert opinion and field data collection were used in six gas power stations of country and by used them RPN are calculated for faults. Finally considering to RPN result and the importance of Wear in journal bearing, this issue is simulated in COMSOL software and using Navier-Stokes equations and load capacity is investigated. At least some suggestions about geometry of journal bearing were presented to improve its performance.
