PURPOSE:To raise a degree of accuracy in centering adjustment, by lowering the push-up force of a condenser supporting spring in time of turbine installation on a spring frame, and converting this force into an increment portion of water load on a condenser in time of operation, thereby performing a centering job. CONSTITUTION:A deck 6 is mounted on a pillar 7 via a spring 8, while turbines 1 and 2 and a generator 3 are installed on this deck. A condenser 4 is supported by a spring 9. These turbines are instaled in the following processes that first, frame pillars are set up, springs are set and locked, and concrete placing of the deck 6 takes place, then the turbine generator is installed there. Next, condenser water load equivalent to that in an operating load is imposed on each frame with the spring 9 adjusted, and afterward, the frame spring 8 is released and adjusted properly, thus coupling centering adjustment takes place. |
