Hi every control forum member
9E gas turbine with mark6e control system.:
I'm working on HGP for one of our gas turbines and before lifting the upper casing we removed all wheel space thermocouples (for upper and lower casing), but two of them was difficult to pull, so they was sheared.
I observed that for the last HGP (about 3 years), the same of one of them was shearing (it's the 2AO2).
Near these thermocouples there's a number and a name incised (for example: 3FO1 985).
Questions: What can be the reasons of this difficulty?
What are the numbers incised near every thermocouple? and if they mean the distance, it will be between what and what?
I read the last topic about these thermocouples but I didn't find this information (thread 1431791163#1431791163).
Best Regards
