A service apparatus for use in maintaining a machine including a stator and a rotor is provided. The service apparatus includes a carriage assembly configured to couple to the rotor. The service apparatus is selectively transitionable between a stowed position in which the service apparatus is rotatable with the rotor and an extended position in which the service apparatus is extended toward the stator. The service apparatus also includes at least one maintenance device coupled to the carriage assembly. The at least one maintenance device is operable to perform a maintenance operation on a surface of the stator with the service apparatus in the extended position.

Service apparatus for use with rotary machines

An alignment system and method for aligning the shaft centerline of rotating equipment positioned on opposing roller stands are provided. The system includes a laser transmission unit on the first stand and a target unit on the second stand. The laser transmission unit includes a laser that transmits a laser beam to a target on the target unit. When the laser beam contacts the center of the target, the roller stands are aligned. The system may be automated to detect the position of the laser beam relative to the target center and to adjust, as needed, the position of one of or both the roller stands using hydraulic cylinders coupled to a roller stand platform. The system and method reduce the time, effort, and manpower required to perform the alignment.

Shaft centerline alignment system for rotating equipment

A portable jig and fixture having at least one base plate, a column assembly removably coupled to the at least one base plate, a slide assembly removably coupled to the column assembly, a power feed head removably coupled to the slide assembly, and a spindle unit removably coupled with the slide assembly having a motor removably engaged it. At least one cutter assembly is removably engaged with the spindle unit and at least one drill jig is also removably engaged with the spindle unit. Also, a turbomachine having complementary structure on the compressor discharge casing can engage with the at least one base plate alignment mounting structure on the portable jig and fixture.

Methods of replacing flex seals in exhaust frames of turbine systems are disclosed. The method may include removing a section of an outer casing of an exhaust frame to form an opening within the outer casing. The section may be formed within a flow path of the exhaust frame. The method may also include removing the flex seal from the exhaust frame via the opening formed within the outer casing, inserting a distinct flex seal within the exhaust frame via the opening formed within the outer casing, and covering the opening formed within the outer casing of the exhaust frame.

An apparatus and method for servicing a combustion liner in a combustion case of a turbine is provided. The apparatus includes an elongated bar having a handle at one end and a force applying member at an opposing end of the elongated bar. An attachment member is configured for attachment to a flange of the combustion case. The attachment member is also configured for pivotal attachment to the elongated bar. The apparatus is configured to apply a radially outward force on a downstream portion of the combustion liner when a radially inward force is applied to the handle.
