Hot-Cold Measurements
Obtaining rotor train alignment changes, component/object movement or expansion due to variations in temperature can be a daunting task. Mechtell can usually make these measurements using state- of-the-art industrial photogrammetry techniques. Our techniques typically show the movement of components relative to other components since, as a rule, there are no components or objects around a power plant that can be considered truly stationary.
Catenary Curves
Catenary Curves can be an important part of determining the positional health of a turbine train and can play a vital part in long term alignment move planning. Mechtell can create partial or complete catenary curves at disassembly, upon reassembly, or with no disassembly. We typically measure catenary curves using the rotor centerlines near each bearing, but we can also measure the bearing bores when the rotors are out. Mechtell uses high definition industrial photogrammetry and/or laser trackers to determine within a few thousandths of an inch, where each measured bearing is located in relation to all the others.
