Metal bellows condition monitoring system

摘要

A system for monitoring conditions associated with a pressure-equalizing bellows element within a seal section of an electric submersible pump assembly. Pressure sensors are associated with the seal section to detect differential pressure across the bellows element.

1. A system for monitoring conditions associated with a pressure-equalizing bellows element within a seal section of an electric submersible pump assembly, the system comprising:
one or more pressure sensors associated with the seal section to detect differential pressure across the bellows element, the bellows element being axially moveable between contracted and expanded positions within the seal section to accommodate a volume of a pressure-balancing fluid; and a controller configured to receive a signal representative of the detected differential pressure and to determine axial position of the bellows element within the seal section based upon the detected differential pressure.
