PREDICTING THE RELIABILITY OF WORK OF CENTRIFUGAL HEAT PUMPS
When operating a centrifugal pump, the greatest danger to the pump is a sudden failure, as a result of which the mechanical part of the unit is destroyed and its performance is lost. There is a need for an emergency pump stop, and the withdrawal of the unit for unscheduled repairs. In this article, we determined and analyzed the dependencies of the time between failures and the availability factor on the level of the technical condition of the pump, determined before the start of operation. The resulting approximating expressions can be used to analyze and predict the reliability of centrifugal pump operation.
