1)
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
operating conditions.
Influencing parameters
The specified values are guideline values and are not guaranteed. The actual values can devi-
ate significantly from the guideline values, for example, due to the following influences:
¡
Fuel quality and fuel treatment
¡
Load profile (thermal cycling, also number of starts/stops, emergency shutdowns, oper-
ating point)
¡
Gas inlet temperature
¡
Turbocharger specification
¡
System-specific operating conditions (combustion quality, exhaust gas composition)
For bearing parts
¡
Lubricating oil quality (oil filtering, oil condition, oil monitoring)
¡
Load profile (speed, pressure conditions, temperature)
¡
Number of starts/stops
¡
Unbalance of the rotor (degree of contamination).
