DFLP Rotor Straightening and Machining

DFLP Rotor Straightening

Mechanical Dynamics & Analysis was contracted to straighten and machine a double flow low pressure (DFLP) rotor from a 3,600 rpm, 103 MW combined cycle power generating unit. The rotor forging arrived with both shaft ends bent. The Turbine end shaft end was bent and found to have a 0.007” total indicator runout (TIR) at […]
