4 Commissioning / 4.2 Inspection procedures

Water-cooled bearing casing

CAUTION

Failure of bearing casing cooling

Any prolonged failure of the water cooling will shorten the lifetime of the

turbocharger.

u Make sure that an uninterrupted supply of cooling water is provided dur-

ing operation.

u Check whether water pipes are fitted on the bearing casing.

4.2.3 Checks after commissioning (engine in idle mode)

Lubricating system

u Keep to the lubricating oil pressure at the inlet.

u Keep to the lubricating oil temperature at the inlet.

u Refer to chapter Monitoring operation →45 for admissible values.

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

If present:

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.

u Compare the measured values with the values of the acceptance report. Different operat-

ing conditions indicate a malfunction (see chapter Eliminating malfunctions →71).

Lubricants and pastes used during assembly can liquefy or vaporise and escape as oily fluids

during the initial hours of operation. Continual escape of an oily fluid indicates an oil leak. If

there is a leak, contact an ABB Turbocharging Service Station.
