SELF-MONITORING SYSTEM FOR EVALUATING AND CONTROLLING ADJUSTMENT REQUIREMENTS OF LEAKAGE RESTRICTING DEVICES IN ROTODYNAMIC PUMPS

摘要

A self-monitoring adjustment system is provided for evaluating and effectingadjustment of the leakage restrictingmechanism between the rotating and non-rotating elements of a rotodynamic pumpto restrict leakage and to establish desired gapdimensions between the rotating and non-rotating elements of the pump. Theadjustment system is structured to be self-monitoringfor determination of when an adjustment of the leakage restricting mechanismis warranted by the conditions of the pump, and isstructured with adjusting mechanisms that are self-adjusting responsive to themonitored conditions of the pump, though manualadjustment is also enabled.
