Centrifugal Pumps in Downstream: Operational Safety Increase

The paper considers an analysis of vibration changes due to strength degradation of centrifugal pumps details while operating at refineries. The analysis revealed sudden changes of vibration in pump units operation. The paper offers a method of separating smooth changes from sudden ones, degradation process monitoring, and prompting personnel on scheduling the units decommissioning for repair and maintenance. Method of long-term diagnostics for the whole operation life of the pump unit is given.
