© Copyright 2020 . All rights reserved.
General maintenance work involves regular visual checks and cleaning
tasks which are intended to ensure the trouble-free functioning of the
turbocharger.
The maintenance points described here are differentiated as follows:
¡
Cleaning during operation:
– Compressor
– Turbine and nozzle ring.
¡
Mechanical cleaning of individual components:
– Filter silencer
– Casings, diffuser, nozzle ring
– Cartridge group: Compressor, turbine
CAUTION
Risk of damage during mechanical cleaning
If mechanical cleaning is carried out too often, this can lead to damage
and corrosion on the components.
If cleaning during operation is not sufficient to achieve acceptable
u
values regarding thermal load and engine performance, mechanical
cleaning of certain spots can be carried out.
Perform mechanical cleaning, especially of the cartridge group, only
u
once within the service interval.
To allow you to observe the standard service intervals and to maintain a
high turbocharger efficiency, ABB Turbocharging recommends that the
cleaning procedure be carried out during operation. This allows the
thermal load of the engine to be kept low while ensuring maximum fuel
efficiency.
Dispose of dirty water and cleaning agents in an environmentally
u
compatible manner, professionally and in accordance with valid local
regulations.
