Abstract

Abstract: The shaft centering of multi-rotor units is complicated and tedious. Repeated calculation and testing are needed in maintenance to reach the optimized result. For this situation, a complete-partial-complete cylinder adjustment scheme is proposed, and a chart-based fast calculation method is provided for turbine-generator shaft adjustment. In this paper, the N335-16.18/538/538 type turbine-generator shaft centering is taken as an example to show the standard establishment, calculation approach as well as the key issues which need to pay more attention in practice. Finally, the technological process and vector diagram method for fastening the coupling bolts of D600A type turbines are presented to provide reference for similar units.

Key words: steam turbine, wheel center, adjustment calculation, coupling, vector diagram
