Maintenance And Online Diagnostics On Gearboxes In The Petrochemical Industry.

Abstract

As a result of cost reductions, there are fewer and fewer gear specialists in compressor and turbine companies, as well as in the maintenance groups of users. Therefore, these groups rely on the gear manufacturer’s expertise for gear maintenance. This paper is based on the authors’ field experience. It uses examples and case studies of investigation and troubleshooting. The use of vibration analysis for gearboxes having multiple sources of excitation is examined. The paper proposes different solutions to increase reliability and availability of gearboxes installed on turbo units. An important chapter deals with modern equipment for condition monitoring, which offers a direct Internet link between site and gearbox diagnostic specialist.
