Investigation of High Bearing Temperature in Centrifugal Compressor
Abstract
Suction side Journal bearing temperature increased to around 130 degC from 60 degC instantaneously. Further the temperature was decreased to 80 degC accompanied by increase in rotor vibration.(from 5 to 15 ?m p-p) •Bearing was inspected and damage to bearing pads was found. Horizontal side bearing clearance was decreased because of shrink the casing at low suction temperature.(roughly -100 degC) As countermeasure, bearing clearance was increased. After that, bearing temperature became stable.
