Operation Manual / TPL76-C32/-C33/-C34/-C35 1 Preliminary remarks / 1.2 Layout and function Mode of operation The turbocharger is a turbomachine and consists of the following main components: ¡ Turbine ¡ Compressor These are both mounted on a common shaft. The exhaust gases from the diesel engine flow through the gas inlet cas- ing (07) and nozzle ring (08) to the turbine wheel.
These data are given on the rating plate. ABB Turbocharging is not liable for any unintended applications and shall reject all warranty claims. [1]Euromot = The European Association of Internal Combustion Engine...
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. 1.4 Deflagration on gas engines ABB turbochargers can withstand a deflagration with a transient pres- sure increase of 12 bar.
1.5 Storage of new turbochargers and spare parts Storage of new turbochargers and spare parts up to 6 months New turbochargers and spare parts from ABB Turbocharging can be stored in sealed packaging without additional mothballing measures for up to 6 months from the date of delivery (marked by the VCI label on the package).
Page 11
Seal the package. The better the external seal is designed, the more permanent the protection. Long-term storage of turbochargers The turbochargers will be prepared for prolonged storage by ABB Tur- bocharging on request. The package is equipped with a hygrometer (see illustration).
Only use original parts from ABB. ABB accepts no liability for any damage resulting from the use of non- original parts and corresponding accessories. Competence of personnel The turbocharger must only be operated and serviced by trained and au- thorised personnel.
