1 Preliminary remarks

1.1 Purpose of this manual

This Operation Manual belongs to the turbocharger with the identical serial number (01), see the cover sheet of the Operation Manual and the turbocharger rating plate.

Operation Manual

This Operation Manual enables you to familiarize yourself with the turbocharger supplied by ABB Turbo Systems and to use it as intended.

It provides important information in order that the turbocharger can be operated safely, correctly and efficiently.

This Operation Manual complements and expands existing national regulations concerning work safety and accident prevention.

Target group

This Operation Manual is intended for engineers and qualified mechanics who are responsible for operating the engine and the turbocharger installed on it.

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 casing (07) and nozzle ring (08) to the turbine wheel.

The turbine wheel (09) uses the energy contained in the exhaust gas to drive the compressor wheel (12). The compressor then draws in fresh air, compresses it and then forces it into the cylinders.

The exhaust gases escape to free air through an exhaust gas pipe which is connected to the gas outlet casing (06).

The air which is necessary for operation of the diesel engine and is compressed in the turbocharger is drawn through the suction branch or the filter silencer (01) into the compressor wheel (12). This air then passes through the diffuser (11) and leaves the turbocharger through the compressor casing (13).

The rotor runs in two radial plain bearings (02/05). One plain bearing is in the bearing bush (04), and the second one is in the axial thrust bearing (03) at the compressor end.

The plain bearings are connected to a central lubricating oil duct which is fed with oil from the engine's lubricating oil circuit. The oil outlet is always at the lowest point of the bearing casing (10).

Turbocharger version with compressor wheel cooling system

Depending on its range of use, the turbocharger is provided with a compressor wheel cooling system. Compressor wheel cooling means that, after the charge air cooler at the engine end, cooled compressor air is delivered to the turbocharger to cool the compressor wheel. In view of the respective operating conditions, it is absolutely essential that the compressor wheel is cooled in order to guarantee its reliability and replacement intervals. In the case of the turbocharger version with compressor wheel cooling, the cooling air is supplied through the side connection (15) in the bearing casing.

2 Safety / 2.8 Periodic checking of the pressure vessel

Hazards due to electrical components

WARNING

Hazards due to electrical components

Electrical components operate with voltages which can present hazards to humans.

u All work on or with electrical components may only be performed by

trained specialists.

u Heed any country-specific regulations.

2.8 Periodic checking of the pressure vessel

The pressure vessels used by ABB, such as those for wet or dry cleaning, are so-called "simple pressure vessels".

Page 26 / 125

¡ The locally applicable legal regulations regarding periodic checks of

the pressure vessels must be observed.

¡ The operating company is responsible for the safe operation of the

pressure vessel.

WARNING

Danger due to pressure vessels

The operating company must make sure the pressure vessels are in proper working condition and monitor them. Necessary repair or maintenance work must be carried out without delay and the required safety precautions must be taken.

u Pressure equipment must not be operated if it has defects.

2.9 Lifting loads

WARNING

Suspended loads

Loads not suspended in compliance with regulations may lead to personal injury or accidents with fatal consequences.

u Loads must always be fastened to technically perfect lifting gear

with sufficient loading capacity.

u Make sure the load is suspended properly on the crane hook.

u Do not let anyone stand beneath a suspended load.

Wear safety gloves to protect against mechanical hazards.

Wear safety helmet.

Operation Manual / TPL67-C.. - TPL71-C..

2 Safety / 2.9 Lifting loads

In the case of two or more suspension points, the slinging angle must not exceed 45°. This avoids excessive loading due to inclined tensile loading.

u Fasten turbocharger assemblies / components as described in re-

spective handling steps.

u Before attaching slings, allow turbocharger components to cool down

(maximum 80°C).

u Use suitable protection at sharp edges.

u Completely screw in assembly / fitting devices without fail so that

they cannot work loose during use.

3 Commissioning / 3.1 Oil supply

3 Commissioning

3.1 Oil supply

A carefully designed and installed oil supply, which functions in all possible operational conditions, is an important prerequisite for troublefree turbocharger operation.

The turbocharger is normally lubricated with oil from the engine oil circuit.

NOTICE

With regard to the oil supply, please observe the engine builder's specifications for lubricating oil selection, oil change intervals, oil filtration, oil pressure and oil temperature.

Page 28 / 125

Oil filtration

Filtration of the lubricating oil using a filter mesh size ≤ 0.034 mm is adequate for TPL67-C turbochargers and a mesh size ≤0.050 mm for TPL71-C turbochargers.

NOTICE

This filtration can also be carried out using an additional self-cleaning fine filter.
