STEAM TURBINE SPEED AND PRESSURE REGULATOR MECHANISM WITH TWO STEAM EXTRACTION UNITS

Upon a change in speed of the turbine, the sleeve of centrifugal governor 1 is displaced up or down, thereby shifting, through levers 10, 11, 12, 13, 14, 15 and 16, the spools of three valves, 2, 3 and 4, in one direction. This actuates the pistons of servomotors 5, 6 and 7, which move three valve members and change the amount of steam admitted into the stages of the turbine. This does not vary th…
