Perfect condition
The turbocharger must be operated in technically perfect condition and
in accordance with its intended application.
ABB Turbocharging shall not accept any liability for damage caused by
unauthorised modifications to the turbocharger or improper operation.
ABB turbochargers can withstand a deflagration with a transient pres-
sure increase of 12 bar.
ABB Turbocharging recommends that, following a deflagration event,
the turbocharger undergoes a visual inspection. Items to check during
this inspection are the position of the turbine casing, of the compressor
casing to the bearing casing, as well as a shifting of the bearing casing in
relation to the bracket. A crack inspection of the casings and the bellows
is also recommended. The nearest ABB Turbocharging Service Station
should be commissioned with this inspection and assessment.
