摘要： A system and method for easily separating upper and lower turbine shells involves forming elongated access pockets vertically aligned across the upper and lower turbine shells and at multiple locations on the turbine shells. Telescoping hydraulic rams are placed into elongated access pockets at each of the multiple locations for lifting the upper shell off of the lower shell. The telescoping hydraulic rams are connected to a controller for controlling each of the rams to operate in parallel with the other rams. Once the turbine shells are separated the upper turbine shell can be removed by conventional block and rigging.

摘要： Bucket tip tenons requiring refurbishment are removed from the bucket tips by grinding. Groups of buckets are clamped on a rotatable table in positions adjacent an induction heating coil and a robotic welding arm, respectively. While one group is preheated, the other group of buckets is in a welding location, enabling the welding head on the robotic arm to sequentially apply weld buildup material to the bucket tips. After applying weld buildup material in multiple passes and sequentially to the bucket tips, the buckets are removed, stress-relieved and the weld buildup material machined to provide refurbished tenons. Upon removal of the buckets from the table, the table is rotated to locate the preheated buckets in welding locations and additional buckets are clamped to the table for preheating.
摘要翻译：需要翻新的铲斗榫头通过磨削从铲斗顶部移除。一组铲斗分别夹在与感应加热线圈和机器人焊接臂相邻的位置的可旋转工作台上。当一组预热时，另一组铲斗处于焊接位置，使得机器臂上的焊接头能够将焊接积聚材料依次施加到铲斗顶端。在多次通过中施加焊接成型材料并依次施加到铲斗前端之后，移除铲斗，减轻应力，并加工焊接成型材料以提供翻新的榫头。从桌子上取下铲斗后，转动桌子将预热的铲斗定位在焊接位置，另外的铲斗被夹紧在工作台上进行预热。

摘要： The temporary fastening system for joining upper and lower shell casings of a turbine to one another for maintenance purposes includes a stud/nut tensioning system employed in lieu of the conventional studs and nuts. Once the turbine is opened up and the inner shell and rotor removed, the upper and lower shell casings are temporarily secured to one another using studs received in registering openings in the horizontal flanges of the upper and lower shell casings and retainer plates serving as a stop for the stud/nut tensioning system. The tensioning system is hydraulically operated and avoids torsional force on the temporary studs. Once measurements are made, the turbine is again reopened and reassembled using the initially removed bolts or a third set of bolts to secure the upper and lower shell casings to one another.

摘要： To accurately axially position and/or seal between axially facing turbine parts, a groove having a cylindrical cross-section is formed in one surface with a centerline offset toward the one surface, the groove opening through the one surface. Rod segments having corresponding cylindrical cross-sections are inserted in the groove. The rod segments have flat surfaces coextensive therewith projecting a predetermined measured distance from the one surface, thereby accurately axially locating the turbine parts relative to one another and forming a seal therebetween. The rod segments have ends abutting one another to seal the segments one to the other.

摘要： Partitions have an airfoil coupled at opposite ends to inner and outer side walls. The side walls each mount radially extending male dovetails. The inner web and outer ring of a diaphragm include complementary shaped dovetail grooves. The male dovetails have reduced diameter portions while the female grooves similarly have corresponding reduced diameter groove portions. The male dovetails are inserted into the female dovetail grooves in an aft direction with stops of the reduced male and female dovetails preventing further movement aft. Seal welds are applied to prevent forward movement of the partitions relative to the web and outer ring.
