Abstract
Not Available A motor-operated valve (MOV) diagnostic system, originally researched at MIT with sponsorship from a nuclear power industry consortium, has been further developed at RH Lyon Corp with sponsorship by the NRC. This MIT/RHL system is non-invasive and may be implemented in either a remote or roving configuration. It uses supply voltage and current signals to determine instantaneous motor torque, and housing vibrations to determine gear meshing and therefore valve travel or position. The resulting torque vs. travel signature has been shown to correlate well with important valve faults such as poor seating, obstructions, tight packing, poor stem nut lubrication, and is expected to diagnose worn or bent stems. This system does not at present detect and classify motor or gearing faults (not a priority in the previous application), but the vibration and electrical signals now captured by the system are the signals of choice for such diagnostics. We propose to augment the current system with gearing and motor diagnostics, and then demonstrate its ability to operate in a shipboard environment. Although the present system is quite portable, we propose to design a board level embedded version, compatible with ICAS, as a Phase I option, for construction and implementation as part of the Phase II effort.
