turbocharger rating plate. Incalculable influencing parameters can
shorten the recommended replacement intervals for the rotor,

encing parameters
.
Non-rotating components
The expected replacement intervals for non-rotating components and
bearing parts are extremely dependent upon system-specific operating
conditions,
see Influencing parameters
.
When the specified, periodic inspections are carried out, the individual
components are inspected for wear and tear and replaced if necessary.
In this way, trouble-free operation is ensured.
Influencing parameters
The following parameters influence the replacement intervals for tur-
bocharger components:
Parameters influencing bearing parts
¡
Poor quality of the lubricating oil (lubrication oil filter system, condi-
tion of lubricating oil)
¡
Unusual loads (vibration, start/stop frequency)
¡
Non-permissible state of rotor unbalance
Parameters influencing non-rotating components exposed to
exhaust gas
¡
Fuel quality (gas, MDO, HFO)
¡
Load profile (thermal load changes, number of starts/stops)
¡
Temperature level of exhaust gas
¡
Turbine cleaning frequency
¡
Procedure for turbine cleaning
