Lubricating system
u Check the oil pressure in the oil supply pipes.
u Check oil inlet temperature.
The admissible values are specified in chapter Monitoring during operation →45.
Leaktightness of pipes
WARNING
Risk of burning from hot gas
Escaping gases are hot and will lead to serious burns in the event of contact.
u Check all pipes for leaks in accordance with the enginebuilder’s instruc-
tions.
Wear safety gloves to protect against thermal hazards.
4.2.4 Checks when starting up the engine
u Measure speed, oil pressure and charging pressure at various engine performances.
u Measure the exhaust gas temperature before and after the turbine.
u Measure the air temperature before and after the compressor.
The measured values must be compared with the values of the acceptance protocol; differ-
ent operating conditions must be taken into account here.
Escape of oily fluids
Lubricants and pastes used for the assembly of the low-pressure and high-pressure stage
can liquefy or vaporise and escape as oily fluids during the initial hours of operation. Con-
tinual escape of an oily fluid indicates a possible oil leak.
In the event of a leak, contact a Turbo Systems service station.
