Hi dears,
We wanted to start a new fr6 GT, at output power about 3 mw. after 2 hours of operating in normal condition, suddenly and simultaneously we had 5 rpm reduction (5163 to 5158), change in wheelspace temp as below, and high spread of exhaust temp from 9c to about 60c.
Wheelspace temps view along stream:
Right, before sudden change, in order: 306, 316, 312,315, 307, 181
Right, after sudden change, in order: 304, 358, 322, 290, 298, 183
Left, before sudden change, in order: 322, 311, 315, 312, faulty, 171
Left, after sudden change, in order: 323, 303, 315, 313, faulty, 173.
Exhaust temp 1 to 18, after sudden change:
290, 311, 315, 312, 301, 291, 310, 312, 314, 314, 311, 297, 280, 266, 247, 257, 271, 290.
Before sudden change, the difference between these temperatures was 9 c.
Rpm change time: 03:11:12 to 03:11:14, after change the value is constant
Spread change time: 03:11:14 to 03:11:20, after change the temps are constant
Ws temps change time: 03:11 to 03:15, after change the temps are constant.
What is the problem of machine?
After this, machine shut down, after 1.5 hour restarted, for 35 mins everything was normal, then we had above problem again.
Machine is a newly bought one.
