A sensor arrangement used for measuring fouling and/or erosion in a machine. A first piezoelectric transducer, a first plate and eventually a first support member form a first vibrating mass. After electrically stimulating the first piezoelectric transducer, the first vibrating mass starts vibrating mechanically and consequently the first piezoelectric transducer generates an electric resonance vibration; the electric resonance vibration is at a resonance frequency depending on the mass of the first vibrating mass. If the mass of the first vibrating mass changes due to fouling and/or erosion by a flow of working fluid in the machine, also the electric resonance vibration frequency changes; such vibration frequency change may be measured and the corresponding mass change may be determined by comparison with a vibration frequency of a second vibrating mass not exposed to the flow of working fluid in the machine.

An apparatus for handling a turbomachine part, particularly during disassembling and reassembling operations. More specifically, an apparatus for handling the stator cone of a gas turbine suitable to completely manipulate the stator cone during disassembling and reassembling operations. The apparatus allows to disassemble and reassemble the stator cone of a gas turbine without the need to dismount the turbomachine enclosure and without the necessity to have personnel inside the turbomachine package during the operations.

Apparatus for handling a turbomachine part

A device for balancing a turbomachine rotor having a driver rotor and a driven rotor is provided. The device comprises a base that is coaxially fixable to the turbomachine rotor and configured to transfer torque from the driver rotor to the driven rotor. The device also comprises at least three balancing tools arranged on the base, each balancing tool (i) defining a respective balancing direction along a radial direction of the base and (ii) comprising: a weight moveable along the respective balancing direction, and a motor configured to move the weight along the respective balancing direction to balance the rotor.

Balancing device for a rotor including multidirectional balancing tools

Method, system and computer software for diagnosing a compressor. The method includes generating a feature vector of the compressor, the feature vector of the compressor including components describing states of various parts of the compressor; determining, based on fuzzy constraints, an aggregated anomaly vector corresponding to the feature vector; defining rules for a preset list of possible faults/failure modes of the compressor; calculating a corroborating measure between the aggregated anomaly vector and the rules; and identifying a fault/failure mode of the compressor based on a result of the corroborating measure.
