Abstract:
A method of transporting a steam turbine which includes a rotor extending along a longitudinal axis and having multistage stationary and moving blades, a casing, supported by a base structure, for enclosing the rotor, bearings for rotationally supporting the rotor, and a pair of glands for sealing between the casing and the rotor, the casing including longitudinally opposite side flanges, the glands being mounted onto gland portions which are provided on the respective sides of the rotor outside of the casing and attached to the respective side flanges of the casing through a pair of flexible members, the method comprising the steps of:removing the glands from the rotor;mounting restrainers to the rotor where the glands had been mounted and to the side flanges of the casing whereby the rotor and the casing are connected to each other to limit the relative movement therebetween and the restrainers bear the weight of the rotor with the bearings; andtransporting the casing and the rotor with the bearings coupled to the rotor.
