METHOD FOR ASSESSING A WEAR STATE OF A MODULE OF A TURBOMACHINE, MODULE AND TURBOMACHINE Russian patent published in 2018 - IPC F04D15/02 

FIELD: hydraulic engineering.

SUBSTANCE: group of inventions relates to a method for assessing a wear state of a module (1, 11, 111, 112) of a turbomachine, of a pump or turbine, of a turbomachine having a signal transmitter (1, 11, 111, 112) and a sensor, and a turbomachine having a module (1, 11, 111, 112) of this type. Assembly contains a bearing arrangement (11, 111, 112) with a mechanical seal and an axial bearing (112) with self-aligning segments with a bearing segment (1121) installed in the bearing body (1122). To assess a wear state by signal transmitter form a mechanical interrogation signal with a given waveform and detect by way of a sensor, which is in contact with the module (1, 11, 111, 112), a response signal generated from the interrogating signal. Response signal is modified depending on a variation in a physical operating variable of the module (1, 11, 111, 112) according to a characteristic sample. Wear parameter is determined from the change in the response signal, and the wear state is assessed using the wear characteristic variable.

EFFECT: inventions are aimed at creating a reliable method for assessing the wear state of a machine assembly outside laboratories, even in extreme manufacture conditions.
