Explanations of the rating plate
The recommended replacement intervals and the corresponding operating limits are jointly
defined with the enginebuilder. This information is specific to the system.
The operating limits of the low-pressure stage are generally different from the operating
limits of the high-pressure stage.
Operation above the indicated values n
Bmax
, t
Bmax
can considerably shorten the recommended
replacement intervals. In such cases, Turbo Systems recommends contacting the nearest
Turbo Systems service station.
n
Mmax
, t
Mmax
normally only apply when running at overload (110 %) during trials on the engine
test bed. These limit values can also be permitted during operation for special applications.
Operation above n
Mmax
and t
Mmax
is not permitted.
Failure to observe the recommended replacement intervals increases the risk of unpredict-
able component failures.
