Abstract: An electronic governor (34) to control a main steam valve (22) of a steam turbine (10) for controlling the rotational speed of a main drive shaft (16). The electronic governor (34) has a housing (36) in which an electric generator (104) is mounted to supply electrical energy to an electronic module (100) mounted on the housing (36). A hydraulic fluid pump (52) is mounted on the housing (36) and supplies fluid to a fluid operated piston (62) to effect a predetermined rotation of an output control shaft (32) and movement of main steam valve (22). Output signals from a microprocessor (116) to solenoid operated valves (96, 98) control the movement of fluid operated piston (62). Pump shaft (46) and generator shaft (48) are in axial alignment with and driven by the main drive shaft (16) to provide all of the power for operation of the electronic governor (34).

Abstract: A lubricant pump (24) for supplying pressurized lubricant to the main bearings (14) of a drive shaft (12) for a steam turbine (10) as shown in FIG. 1. A lubricant pump (24) is positioned between a governor (18) and an adjacent bearing (14) with the governor (18) and lubricant pump (24) being driven from the turbine shaft (12). The lubricant pump (24) has an outer housing (56) with a pair of opposed parallel mounting faces (58, 60) for mounting against a planar end face (48) of a bearing housing (44) on one side of lubricant pump (24) and an opposed planar face (38) of governor (18) on the other side of lubricant pump (24). Lubricant pump (24) comprises a rotary gear pump and may be easily installed on an existing turbine (10) having a governor (18) mounted on a bearing housing (44). Lubricant pump (24) includes gears ( 90, 92) to supply pressurized fluid through lubricant lines (30, 32) to bearings (14).
