Abstract: Methods for retrofitting a turbomachine are provided. A first trip cup of the turbomachine may be replaced with a second trip cup. The first trip cup may include a throw-out arm connected to a first trip cup spring. The second trip cup may include a plunger disposed in a hole defined by the second trip cup and a plunger spring encircling the plunger in the hole. The first trip cup may be removed from the turbomachine and the second trip cup installed such that a location of the plunger in the turbomachine is the same as a location of the throw-out arm in the turbomachine when the first trip cup was installed on the turbomachine. The tension in the plunger spring may be adjusted such that, when a speed of the turbomachine exceeds a predetermined value, the plunger actuates a trip paddle located adjacent the second trip cup.

Abstract: A method for retrofitting a turbomachine is provided wherein a first trip cup of the turbomachine is replaced with a second trip cup and by replacing a mechanical flyweight governor with a mechanical-hydraulic governor. The second trip cup includes a plunger disposed in a hole defined by the second trip cup. The first trip cup is removed from the turbomachine and the second trip cup installed such that, when a speed of the turbomachine exceeds a predetermined value, the plunger actuates a trip paddle located adjacent the second trip cup. The mechanical flyweight governor is removed from the turbomachine and a first set of governor linkages coupling the mechanical flyweight governor to a steam source. The mechanical-hydraulic governor is installed in the turbomachine, the mechanical-hydraulic governor being coupled to a shaft of the turbomachine and being coupled to the steam source via a second set of governor linkages.
