Real-time condition monitoring of thermal power plants feed-pumps by rolling bearings supports vibration

The report addresses the real-time condition monitoring of technical state and automatic vibration analysis of auxiliary equipment’s bearing supports, in particular, the control of the feed-pump operating modes of thermal power stations. The causes that lead to premature birth and development of defects in rolling bearings are identified and the development of activities ensuring safe and continuous operation of the auxiliary equipment of thermal power stations is carried out.

Collection and analysis of vibration parameters of pumping units during their operation are realized by means of real-time condition monitoring. Spectral analysis of vibration parameters of one of the pumps showed the presence of frequency components, which mark violations in the operating practices of the pump, the development of imbalance and, as a consequence, the development of defects in the bearings after a long-term operation of the unit.

Timely warning of the personnel on the operation of the unit with "UNACCEPTABLE" state and automatic warning about the required changes the operational process allows to recover the pump operational process in due time and prevent further development of defects.
