Expected replacement intervals
Rotating components
The recommended replacement intervals for compressor wheels and turbine wheels are spec-
ified based on the safety concept for rotating parts (SIKO) and dependent on the operating
conditions. These intervals are shown on the rating plate of the turbocharger.
Non-rotating components
Depending on the system-specific operating conditions, a differentiation must be made be-
tween 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 dras-
tically reduce the replacement interval of these parts.
During the prescribed periodic service work, the individual parts are examined for wear and
replaced if necessary.
Influencing parameters for bearing parts
Inferior lubricating oil quality (lubricating oil filtering, lubricating oil condition)
Exceptional stresses (vibrations, start/stop frequency)
Inadmissible unbalance of the rotor
Influencing parameters for exhaust gas-charged, non-rotating components
Fuel quality (gas, MDO, HFO)
Load profile (thermal cycling, number of start/stop cycles)
Temperature level of the exhaust gas
Frequency of turbine cleaning
