Couplings and Rotating Machines
MetadataShow full item record
This course covers the application of couplings and rotating machines. Initially the driver and driven machines are analysed together with their characteristics, and how they affect the coupling. The various types of coupling in the market are covered next, including rigid and flexible designs, and where they are utilised. Then the oil and gas industry requirements are investigated, and why certain couplings are preferred. Selection is reviewed next, and the coupling choice is derived from the data provided by the customer, it includes sections on shaft end connections, balancing and shaft alignment. The selection section is also supported by a part on standards with the focus being on API 610 and API 671. The course concludes with failure analysis and reviews the main factors affecting coupling failure from misalignment to torsional vibration.
