Operating limits and replacement intervals The recommended replacement intervals and the corresponding operating limits in chapter 3 are jointly defined with the enginebuilder. This information is specific to the product. Non-observance of the recommended replacement intervals and the operating limits increases the risk of unpre- dictable component failures.

Non-insulated low-pressure and high-pressure stages can cause serious in- juries to personnel (burns). ABB Turbo Systems supplies the low-pressure and high-pressure stage with or without insulation in accordance with the purchase order received from the enginebuilder. If supply is without insulation, the enginebuilder is re-...

If the engine can be stopped temporarily: Inspect air lines, exhaust gas pipes and the low-pressure and high-pressure stages and remedy any malfunctions. In any case, contacting the nearest ABB Turbocharging Service Station is recommended. 4.3.4 Malfunction of the speed measurement system The possible reasons for malfunction of the speed measuring system are described in →44.

Compressor cleaning We recommend cleaning the HP compressor after the LP compressor. On V-engines with several low-pressure and/or high-pressure stages per engine, ABB Turbo Systems recommends the parallel cleaning of the LP compressors as well as the parallel cleaning of the HP compressors.

Do not clean the compressors of the different high and low-pressure stages at the same time, but one after the other. On V-engines with several low-pressure and/or high-pressure stages per engine, ABB Turbo Systems recommends the parallel cleaning of the LP compressors as well as the parallel cleaning of the HP compressors.

Gradually reduce the engine load. Have the cause clarified and remedied immediately by an ABB Turbochar- ging Service Station. Have parts assessed for damage and, if necessary, replaced by an ABB Turbocharging Service Station. Sporadic surge blows Surging of the low-pressure stage can occur during certain operating states, such as when reducing the engine performance quickly when manoeuvring.
The engine lubricating oil is replaced by a preservative oil and circulated with the pre-lub- rication pump before the engine is taken out of operation. If neither of the criteria above are met, mothballing by an ABB Turbocharging Service Station is necessary. This includes cleaning and applying preservative oil to the relevant compon- ents.
