MD&A 7FH2 Spring Migration Repair

Mechanical Dynamics & Analysis (MD&A) experts offer a unique, patented repair process that eliminates the axial migration of slot leaf springs within 7FH2 generator fields.  This repair can also be applied to 324 generator fields.

The blockage of the radial ventilation passages results in reduced hydrogen gas cooling flow, which can lead to thermal instabilities with the rotor leading to excessive rotor vibration and forced outages.
