How to Address Vibration in a Turboexpander Equipped with Active Magnetic Bearings

Turbomachinery International – March/April 2020 Tadeh Avetian, Luis E. Rodriguez and Junyoung Park How to Address Vibration in a Turboexpander Equipped with Active Magnetic Bearings L.A. Turbine and Samsung engineers discuss the diagnostic process and root cause analysis findings leading to the redesign of the active magnetic bearing turboexpander.

Qualified Active Magnetic Bearing Retrofits for Turboexpanders

Learn how turboexpander magnetic bearing retrofits can boost production, extend equipment life and reduce vibration in a case study co-authored by L.A. Turbine and Waukesha Magnetic Bearings. Redesign options for the active magnetic bearing (AMB) system include a controller upgrade that maintains the original hardware and sensors or perform an upgrade of the controller and the AMB components. Both approaches are tested and proven to positively impact performance and robustness of the AMB turboexpander being used for hydrocarbon processing.
