Centerline helps solve turbine problems
Centerline Software, Abilene, TX, offers alignment consulting and complete field engineering services for steam turbine generator maintenance.
Using its Turbine Tools software, it is able to calculate and optimize multiple shaft coupling alignment. The company says that Turbine Tools 4.0 lets clients:
1. Calculate two different standard lines of
Centerline Software says that the Turbine
Tools 4.0 program includes multiple shaft rim and face coupling alignment
and provides proposed move optimization and custom coupling
calculations not available with laser coupling alignment systems. The
Turbine Tools 4.0 is designed to find the best possible alignment requiring the smallest moves on the fewest bearings and the best possible alignment without moving the generator.
Turbine Tools 4.0 includes Turbine Tools 2.5 plus multiple shaft coupling alignment. Turbine Tools 2.5 was designed specifically for the mechanical alignment of all rotating machinery, including steam and gas turbine generators, centrifugal pumps, compressors, fans and so on. As a complete package for power plant maintenance, the program also offers a range of tests including tightwire and diaphragm alignment, bearing shims, bolt stretch and generator air test.
Turbine Tools 4.0 also includes the generator foot step shim calculations.
A typical field case illustrates the possibilities offered by Turbine Tools. The initial standard line indicated it would be necessary to move eight bearings with the largest move 0.027. By running the proposed move optimization, in a few minutes it was found that all couplings could be aligned within tolerance by moving only five bearings with the largest move 0.016. The program quickly found a way to save the time required to make three bearing moves.
• As well, REACT Ltd., Isle of Palms, SC, (REACT — Rotating Equipment Alignment Consultants and Trainers) and Centerline Service now offer a combined turbine outage service with laser alignment of internal components and multiple shaft coupling alignment. PI
