ABSTRACT
Today’s energy systems increasingly use various types of microturbines to produce electricity. A specific feature of such
machines is a high-speed rotor, whose rotational speed can be higher than 100,000 rpm. Failure-free operation of highspeed microturbine rotors requires both special design and high precision during the manufacturing process. What
is more, proper procedures must be followed during run-up and coast-down phases; and also, dedicated diagnostic
systems have to be used. This article discusses the experimental research conducted on a 2.5 kW vapour microturbine
that operated in a prototypical combined heat and power plant. A series of measurements was carried out to evaluate the dynamic performance of the machine during normal operation. After the appearance of certain defects in the
rotating system, it was necessary to perform a new series of measurements in order to assess the dynamic properties of
the machine. The measurements results obtained in the form of vibration velocity spectrums made it possible to define
diagnostic symptoms corresponding to particular defects. Similar diagnostic symptoms can occur during the operation
of this class of turbomachines.
