Abstract
A system is provided for balancing a movable turbine part of a turbine or of a compressor. The system includes a balancing weight element with a first hole and a second hole and a fixing element. The first hole and the second hole are formed in such a manner that the fixing element is detachably insertable in either the first hole or the second hole. The first hole is formed in such a manner that the inserted fixing element in the first hole detachably couples the balancing weight element to the movable turbine part in a spatially fixed position. The second hole is formed in such a manner that the fixing element is receivable in the second hole.

A system for balancing a movable turbine part of a turbine or of a compressor, the system comprising
- a balancing weight element with a first hole and a second hole, and
- a single detachable fixing element,
- wherein the first hole and the second hole are formed in such a manner that the single detachable fixing element is detachably insertable in either the first hole or the second hole,
- wherein the first hole is formed in such a manner that the inserted fixing element in the first hole detachably couples the balancing weight element to the movable turbine part in a spatially fixed position,
- wherein the second hole is formed in such a manner that the fixing element is receivable in the second hole, and
- wherein when the balancing weight element has been non-detachably secured to the movable part, said fixing element is received within the second hole,
- whereby the over-all weight of the system remains unchanged between a detachably spatially fixed position and a non-detachably secured position of the balancing weight element.
A method of balancing a movable turbine part of a turbine or of a compressor, the method comprising
- positioning a balancing weight element at a spatially fixed position of the movable turbine part,
- detachably coupling the balancing weight element to the movable turbine part at the spatially fixed position by inserting a fixing element in a first hole of the movable turbine part,
- testing whether the movable turbine part is balanced, and if the movable turbine part is balanced,
- non-detachably fixing the balancing weight element at the spatially fixed position to the movable turbine part, and
- inserting the fixing element in a second hole of the balancing weight element, when the balancing weight element is non-detachably fixed in the spatially fixed position.
