The turbocharger rotor assembly / rotor complete consists of
compressor impeller, blade shaf/turbine shaft/rotor shaft and
partition wall complete.
The compressor impeller is of aluminium alloy or the more expensive
titanium. Manufactured from a single casting it is located on the
rotor shaft by splines. Aluminium impellers have a limited life,
due to creep, which is dictated by the final air temperature. Often
the temperature of air leaving the impeller can be as high as
200°C. The life of the impeller under these circumstances may be
limited to about 70000 hours.
The turbocharger rotor shaft is equipped with components such as a compressor and a turbine impeller, and has a complicated structure and a large weight. If the ship is parked for a long time, the turbocharger rotor will be bent and deformed due to the long-term non-operating self-weight, which will break the matching gap between the rotor and the casing, the gas seal and the casing, and the rotor will be lost.
