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 restricting mechanism between the rotating and non-rotatingelements of a rotodynamic pump to restrict leakage and to establish desired gapdimensions between the rotating and non-rotating elements of the pump. The adjustmentsystem is structured to be self-monitoring for determination of when an adjustmentof the leakage restricting mechanism is warranted by the conditions of the pump,and is structured with adjusting mechanisms that are self-adjusting responsiveto the monitored conditions of the pump, though manual adjustment is also enabled.
