ABSTRACT:
A self-monitoring adjustment system is provided for evaluating and effecting adjustment of the leakage restricting mechanism between the rotating and non-rotating elements of a rotodynamic pump to restrict leakage and to establish desired gap dimensions between the rotating and non-rotating elements of the pump. The adjustment system is structured to be self-monitoring for determination of when an adjustment of the leakage restricting mechanism is warranted by the conditions of the pump, and is structured with adjusting mechanisms that are self-adjusting responsive to the monitored conditions of the pump, though manual adjustment is also enabled.
