Offenbart sind ein Verfahren zum Austauschen einer Schaufel (12) eines Rotors (2) mit integraler Beschaufelung, wobei eine Neuschaufel (22) an einen auf einer rotorgrundkörperseitigen Trennfläche (28) errichteten Sockel (34) gefügt wird, sowie ein nach diesem Verfahren reparierter bzw. instandgesetzter Rotor.
摘要:
A turbine blade and a process for manufacture of turbine blades is provided comprising: casting as one piece a blade body (18) and a first portion of an airfoil; forming a tip section having a tip cap (23) and a second portion of an airfoil which is sized to fit on the first portion of the airfoil; and attaching the first portion of the airfoil to the second portion of the airfoil. A process for repairing turbine blades is provided which comprises: removing the tip cap (23) and a portion of the airfoil from the blade to form a repair surface on the airfoil; forming a replacement tip section comprising a replacement tip cap (20) and a replacement portion of the airfoil sized to fit onto the repair space; and attaching the replacement tip section (20) to the repair surface.
摘要:
Method for manufacturing a wall structure comprising the steps of providing two walls (106, 110) at least substantially in parallel to one another and at least two webs (107, 109) that connect the two walls and delimit a cooling channel (115) between said walls, said cooling channel extending in a divergent manner from a narrow cooling channel section (111). The method further comprises the step of providing an intermediate web (108) between said two webs (107, 109) so that it connects the two walls (106, 110) and divides a single diverging cooling channel (115) into two separate cooling channels (215, 315) and positioning the intermediate web (108) so that it ends at a distance from the narrow cooling channel section. The method further comprises the step of depositing material (119) on an outer surface of one of said walls (110) opposite an end position (117) of the intermediate web.
摘要:
The invention relates to a method for manufacturing a stator or rotor component which is intended during operation to conduct a gas flow. A first wall part (14, 15) is placed with its one edge bearing against the flat side of a second wall part (9, 10), extending in the radial direction of the component, in such a way that the first wall part extends in the circumferential direction of the component. The edge of the first wall part is then laser-welded to said second wall part from an, in the circumferential direction, opposite side of the second wall part in relation to the first wall part in such a way that the joined-together portions of the wall parts form a T-shaped joint.
