Abstract
A stator vane removal system includes a reaction platform configured to couple between opposing sides of a slot defined in an inner surface of a casing of a rotary machine. At least one stator vane is retained in the slot. The reaction platform includes at least one wedge surface. The system also includes an actuator configured to couple to the reaction platform. The at least one wedge surface facilitates inducing a coupling force exerted by the reaction platform to the opposing sides of the slot when the actuator applies a pushing force to the at least one stator vane in the slot.
Claims20
A stator vane removal system comprising:
- a reaction platform configured to couple between opposing sides of a slot defined in an inner surface of a casing of a rotary machine, wherein at least one stator vane is retained in the slot, said reaction platform comprises a block and at least one sleeve configured to slidably couple to said block along at least one wedge surface;
- and
- an actuator configured to couple to said reaction platform, said at least one wedge surface is configured to induce a coupling force exerted by said reaction platform to the opposing sides of the slot in response to a pushing force applied by said actuator to the at least one stator vane in the slot.
A stator vane removal system comprising:
- a reaction platform configured to couple between opposing sides of a slot defined in an inner surface of a casing of a rotary machine, wherein at least one stator vane is retained in the slot, said reaction platform comprises at least one wedge surface;
- and
- an actuator configured to couple to said reaction platform, said at least one wedge surface oriented to react a pushing force applied to the at least one stator vane in the slot by said actuator such that a coupling force is exerted by said reaction platform to the opposing sides of the slot in a direction substantially perpendicular to the pushing force.
A stator vane removal system comprising:
- a reaction platform configured to couple between opposing sides of a slot defined in an inner surface of a casing of a rotary machine, wherein at least one stator vane is retained in the slot, said reaction platform comprises at least one wedge surface;
- and
- an actuator configured to couple between said reaction platform and the at least one stator vane such that said actuator is disposed at least partially between the opposing sides of the slot, said at least one wedge surface is oriented to induce a coupling force exerted by said reaction platform to the opposing sides of the slot when said actuator applies a pushing force to the at least one stator vane in the slot.
