Perfect condition
The turbocharger must only be used when it is in a technically flawless condition and oper-
ated in compliance with its intended use.
ABB excludes any liability for damage resulting from unauthorized modifications to the tur-
bocharger or improper operation.
2.6
Deflagration on gas engines
ABB turbochargers can tolerate a deflagration with a transient pressure increase of 12 bar.
After a deflagration event ABB recommends verifying the following points on the turbochar-
ger:
¡
Position of the turbine and compressor casings to the bearing casing
¡
Shifting of the bearing casing in relation to the bracket
¡
Cracks in casings
If during external inspection anomalies are found or if a particularly strong deflagration
event has taken place, it is also recommended to check the bearings of the turbochargers
before the next start. An ABB Turbocharging Service Station should be instructed to carry
out this inspection.
2.7
Periodic check of the pressure vessels
The pressure vessels used by ABB Turbocharging, such as those for wet or dry cleaning, are
so-called "simple pressure vessels".
¡
The locally applicable legal regulations regarding periodic checks of the pressure vessels
must be observed.
¡
The operating company is responsible for the safe operation of the pressure vessel.
WARNING
Danger due to pressure vessels
The operating company must make sure the pressure vessels are in proper
working condition and monitor them. Necessary repair or maintenance work
must be performed promptly, and the required safety measures must be
taken.
u
Pressure equipment must not be operated if defects are present.
