CS12 Motor Drive Pulley Steady Bearing Failure
K4420-3 is a two stage in-line reciprocating compressor which is driven by a two speed (960/400 rpm) Laurence Scott electric motor via a 9 belt pulley system giving a compressor speed of either 345 rpm or 144 rpm respectively.
Historically, the overall vibration levels throughout the machine had been consistently low and had never given any cause for concern, however, the overall vibration levels recorded on 30 September 1997 at the motor drive pulley outboard steady bearing exhibited a marked increase in the axial direction.
Due to the accurate analysis and prompt action by the Engineering Department a catastrophic failure had been prevented with a mechanical cost saving of several thousand pounds.
