Abstract

A mechanical seal assembly with an electronically controllable carrier load. The assembly includes a magnetic ring affixed to the carrier and driven by a solenoid. The solenoid can apply an axial force to the carrier. The carrier load can be controlled to prevent or reduce friction between the primary ring and mating ring in slow-roll running conditions by partially or completely compensating a spring force provided by a biasing mechanism. The carrier load can further be controlled to inhibit seal hang-up. In embodiments, desired the carrier load can be determined by rotational speed. In embodiments, carrier load can be determined based on sensor signals.
