METHOD AND DESIGN FOR MONITORING THE STATE OF THE SPIRAL CASE OF A CENTRIFUGAL PUMP

摘要

Monitoring a condition of a volute casing of a centrifugal pump. The condition monitoring takes place by arranging blind holes (30') in the outer surface (26) of the wall (22) of the volute casing to such a location that the stress subjected to the volute casing is at its highest. The blind hole (30') may be provided with a pressure sensor (32') coupled to a pump control system.
