Expected replacement intervals

Rotating components
The recommended replacement intervals of the compressor and turbine wheels are spe-
cified with the aid of the safety concept for rotating parts (SIKO) and dependent on the op-
erating conditions. These intervals are shown on the rating plate of the low-pressure and
high-pressure stage.
Non-rotating components
Depending on the system-specific operating conditions, a differentiation must be made
between the intervals to be expected for:
¡
replacing the bearing parts and
¡
replacing the non-rotating components exposed to hot gas.
A decisive role is played by various influencing parameters which, in extreme cases, can
drastically reduce the replacement interval of these parts.
During the prescribed periodic service work, the individual parts are examined for wear and
replaced if necessary.
