Operating condition and replacement intervals

The operational limits for the turbocharger nBmax, tBmax, nMmax, tMmax, inspection- and replacement intervals for the compon-ents concerned on the rating plate are valid for the operational mode and compressor inlet condition, which has been agreed upon between the engine builder and ABB.

Note: Replacement intervals of components depends on the load profi le, turbine inlet temperature, suction air temperature and turbocharger speed. In case the operation conditions differs signifi cantly from what is considered to be normal for the cur-rent application, it is recommended to contact ABB for a re-calculation of replacement intervals. Frequent load alterations, high temperatures and high speed lower the life of components.

Unless otherwise agreed, the application limits nMmax, tMmax are valid for the test operation for a limited time.

2.1

Mode of operation

The turbocharger is a turbomachine consisting of the following main com-ponents:

turbine compressor

These are mounted on a common shaft.

The exhaust gas from the diesel or gas engine flows through the gas inlet casing (9) and nozzle ring (8) to the turbine (7).

The turbine (7) uses the energy contained in the exhaust gas to drive the compressor wheel (11). The compressor draws in fresh air, compresses it and then forces it into the engine's cylinders.

The exhaust gas escapes into the ambient air through the exhaust gas pi-pe, which is connected to the gas outlet flange (6).

The air, which is necessary for operation of the diesel or gas engine and which is compressed in the turbocharger, is drawn into the compressor wheel (11) through the suction branch or filter silencer or through an axial suction pipe. It then passes through the diffuser (2) and leaves the turbo-charger through the outlet on the compressor casing (1).

The rotor runs in two radial bearings (4/5) which are located in the bearing flange between the compressor and the turbine. The axial thrust bearing (3) is located at the compressor end.

The radial 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).

1.6.1 Explanation of the rating plate

The recommended replacement intervals and the corresponding opera-tional limits are jointly defined with the engine manufacturer. This informa-tion is specific to the system.

Operation above the indicated values nBmax, tBmax can considerably shorten the recommended replacement intervals. In such cases, we recommend that you contact the nearest official service station of ABB Turbo Systems. nMmax, tMmax normally apply only when running at overload (110%) during trials on the engine test bed. These limits can also be permitted during operation for special applications. Operation above nMmax and tMmax is not permitted. Non-observance of the recommended replacement intervals can increase the risk of unpredictable component failures.

2.5 Hazards during operation and maintenance

Mechanical hazards during operation

During normal operation, no mechanical hazards emanate from the turbo-charger if it has been installed properly.

Risk of injury Contact with rotating parts can lead to serious injuries. The turbo-charger must never be operated without a filter silencer or an air suction branch. When the engine is at a standstill, the rotor can turn on its own because of stack draught.

Operate the turbocharger in accordance with instructions. During maintenance work, secure the rotor against unintentional ro-

tation.

Mechanical hazards when working on the turbocharger

During maintenance work, various risks can occur through the improper handling of components, through the non-observance of work instructions, due to inadequate care or as a consequence of insufficient training.

Mechanical hazards Serious personal injuries or accidents with fatal consequences can oc-cur through mechanical influences as a result of risky, improper working methods.

Heed the general rules for work safety and accident prevention. Ensure the safety of the work area. Perform only those tasks that are described in this manual. Perform work only for which training has been carried out.

Hazards due to hot surfaces and substances

During operation, turbocharger surfaces and attached parts as well as op-erating materials (lubricating oil) become hot. The surface temperature is dependent on the effectiveness of the insulation being used. The tem-perature can become high enough so that it falls into ranges where burns are possible.

Risk of burning Touching hot surfaces or contact with hot operating materials can lead to serious burns.

Do not touch hot surfaces and heed the warning plate on the turbo-charger.

Wear heat-resistant protective gloves and protective clothing. Allow the turbocharger to cool down before carrying out any work.

Hot surfaces on uninsulated turbochargers Uninsulated turbochargers can cause serious personal injuries (burns). The turbocharger is supplied by ABB Turbo Systems without insulation depending on the order from the engine builder. In this case, the engine builder is responsible for insulating the turbocharger properly or for pro-viding protection against hot surfaces being touched. The engine builder's instructions and specifications about protection

against hot turbocharger surfaces must be observed in every case.

Hazards due to operating and auxiliary materials

Operating and auxiliary materials are substances used for operation or the execution of maintenance work. Oils, greases, coolants, cleaning agents and solvents, acids, etc. can be regarded as hazardous materials. Operat-ing and auxiliary materials can be combustible and easily ignited.

Risk of poisoning, burning Ingestion or inhalation of vapours of the corresponding operating and auxiliary materials or contact with such can cause damage to health.

Avoid inhalation and contact with the skin. Wear protective clothing and a breathing mask.

2.6 Use of ABB turbochargers on gas engines ABB turbochargers withstand a deflagration with a transient pressure in-crease of 12 bar. A maximum of 11 bar was measured during deflagration trials on engines with flame traps. Field operating experience of well-known gas engine builders supports this value. In the past, no damage to ABB turbochargers was ascertained after deflagration incidents.

ABB Turbo Systems recommends that the turbocharger is inspected visu-ally after a deflagration incident. During this inspection, the positions of the turbine casing and the compressor casing relative to the bearing cas-ing as well as any shifting of the bearing casing relative to the bracket must be checked. An inspection of the casing for cracks is also recom-mended. The nearest ABB Turbocharger service station should be com-missioned with this inspection and assessment.

3 Commissioning 3.1 Oil supply

A carefully designed and installed oil supply, which functions in all possi-ble operational conditions, is an important prerequisite for trouble-free tur-bocharger operation.

The turbocharger is normally lubricated with oil from the engine oil circuit. If a separate lubricating system is used, then emergency lubrication is al-so to be provided.

Heed the instructions of the engine builder when selecting the lubricat-ing oil and oil-change intervals.

Oil filtration

To avoid hazardous wear of bearing parts and bearing in mind the tur-bine specifications as well as the bearings used, impurities of different size must be filtered out of the lubricating oil.

Oil filtration down to 34 µm is specified as standard for the turbocharger. This means that impurities larger than 0.034 mm must be filtered out of the oil with a separation efficiency > 99%.

Fit an accessory filter if engine oil filter is not efficient enough. Arrange for a bypass to be activated that ensures oil is supplied to tur-

bocharger by circumventing filter when engine is cold started and dirty deposits in accessory filter cause flow resistance to rise above 0.5 bar.

Check that oil filters are clean before every start-up.

Also follow the engine builder's instructions regarding filter mesh size and separation efficiency.

Lubricant

All lubricating oils used for engines are admissible.

Gas, air and oil lines

Check all gas, air and oil lines for leaks after starting the engine. Tighten the V-clamps once to 60 Nm.

Further periodic tightening of the V-clamps is not necessary or recom-mended. Too frequent tightening can lead to wear on the connection.

3.2.3 Check when running up engine

Measure the oil pressure and charging pressure at various engine per-formance levels.

Measure the exhaust gas temperature in front of and behind the tur-bine

Measure the air temperature in front of and behind the compressor.

The measured values must be compared with the values in the accep-tance test report while taking different operating conditions into account.

Lubricants and pastes used during assembly of the turbocharger liquefy or vaporise and might escape as an oily liquid in the first few hours after commissioning. If additional oily liquid continues to escape after this pe-riod, look for the cause of a possible oil leak. The first step is to check for leaks in the oil supply to the turbocharger. If this is not in proper condition, contact an ABB Turbocharger service station.

3.2.4 Inspection after 100 service hours

Clean or replace lubricating oil filters after the first 100 service hours.

Hazards due to noise The noise can cause impaired hearing, damage to health, mental dis-turbances, irritation and diminished attention.

Always wear ear protectors when engine is running. When noise level is above 85 dB(A), always wear ear protectors.

The sound pressure level (A-weighted) of emissions is measured at a dis-tance of 1 metre from the turbocharger.

The highest sound pressure level of emissions1) reaches a maximum of 105 dB(A) near the filter silencer and over the entire speed range.

The following prerequisites must be fulfilled on the turbocharger in order to observe this limit:

A filter silencer is fitted. All standard, noise-reducing measures have been taken2). The bellows at the air outlet have been perfectly insulated acoustically

by the engine builder. He is also responsible for insulating the charge air / scavenging air pipe and the charge air cooler.

1) Directive 2006/42/EC, 1.7.4.2 / u / paragraph 5 + 7 : A-weighted sound pressure level of emissions

2) In the event of divergent insulation designs, the engine builder must ensure that equivalent acoustic insulating measures are ta-ken.

5.2 Cleaning the compressor during operation How dirty the compressor stage (compressor wheel and diffuser) be-comes, depends on how clean the drawn-in air is.

Deposits of dirt can build up in the flow ducts if the following substances are in the intake air:

Oily or salty mist Solid combustion residues Various kinds of dust

Dirty deposits on the compressor stage have a negative influence on the compressor efficiency and the charging pressure.

This results in higher exhaust temperatures and higher fuel consumption by the engine. Dirty deposits on the compressor can also increase rotor unbalance.

Under no circumstances is periodic cleaning of the compressor during op-eration a substitute for the service work carried out when the turbocharger is completely dismantled and the compressor is cleaned mechanically.

If the coating of dirt is very thick and hard, the compressor can only be cleaned manually when disassembled. This cleaning should be carried out by an ABB Turbocharger service station.

The interval between periodic cleaning is very dependent on the operating conditions. In general, cleaning should be carried out every 25 to 100 op-erating hours.

Cleaning intervals Should the specified cleaning intervals prove incompatible with engine operation, please contact ABB Turbo Systems.

Cleaning method

Cleaning the compressor while in operation is carried out as wet cleaning. This cleaning method has been tested and approved by ABB Turbo Sys-tems.

To clean the compressor stage while in operation, water is injected in front of the compressor wheel from an injection pipe that is built in the filter si-lencer or suction branch.

The water does not act as a solvent in the process, but the deposit is re-moved by the mechanical impact of the drops. This is a very suitable pro-cess, provided that the build-up of deposits is not too advanced.

Corrosion and deposits when cleaning Damage and impairment of turbocharger parts due to salt water and cooling water additives Always use only clean water for cleaning.

The injection pipe must on no account be connected directly via a cock to a water pipe or a dosing vessel larger than the one supplied. This prevents uncontrolled volumes of water entering the turbocharger and engine, which can lead to serious damage.

In the case of V-engines with several turbochargers on each engine, we recommend parallel cleaning of the compressors. This cleaning process is faster and the risk of turbocharger surging is reduced.

In the case of sequential charging, care must be taken to ensure that tur-bocharger compressors are cleaned regularly, especially after periods of operation in the lower performance range.

5.2.1 Wet cleaning compressor using external water pressure vessel (XC1)

These instructions for wet cleaning apply only when cleaning is carried out with clean water and the engine manufacturer permits the process.

Supplying water from the externally mounted water vessel is suitable only for those applications where a negative pressure exists in front of the compressor wheel (not used for: blowers connected in front of the compressor or high-pressure compressor stages with two-stage charg-ing).

Operating condition prerequisites for compressor cleaning with XC1

In order to carry out a satisfactory cleaning process that has been tested and is recommended by ABB Turbo Systems, the following pre-requisites must be met:

Full engine load if possible High turbocharger speed Start cleaning cycle according to following description in Procedure

for wet cleaning with XC1.

Procedure for compressor wet cleaning with XC1

X Screw plug D Pressurized air Y Valve activator W Water Z Container

Remove the screw plug (X). Fill the vessel with clean water. Replace the screw plug. Push the valve activator (Y) against the spring and hold it for 10 to 15

seconds until entire volume of water has been injected. After cleaning, wait at least 5 minutes with the engine running to allow

the turbocharger to dry. The cleaning cycle may only be repeated after a stabilisation period of

at least 10 minutes has elapsed.

Whether or not cleaning has been successful can be seen from the charging or flushing pressure and also from the exhaust gas tempera-tures. If the cleaning operation is not satisfactory, it can be repeated up to two times. If the cleaning result is still not satisfactory after three attempts and the engine values are also unsatisfactory, we recommend that the turbo-charger be inspected and cleaned by an official ABB Turbocharger ser-vice station.

Normal behaviour, not a malfunction Turbo-charger

A minimal and uniform wear at the circumference of the rotor com-ponents, caused by slight local rubbing against adjacent compo-nents is permitted. This causes the compressor or turbine blades to be somewhat shortened. To prevent significant loss of efficiency, specific tolerances must be fulfilled. If there is any doubt about the extent of the rubbing, contact an

ABB Turbocharger service station. Have a dimensional check carried out by an ABB Turbocharger

service station.

Sporadic surge blows

Surging of the turbocharger can occur during certain operating conditions such as when reducing the engine performance quickly when manoeu-vring. At the same time, the flow direction in the compressor is momentar-ily reversed. Such sporadic surge blows do not impair the safe operation of the turbocharger.

A surge blow is accompanied by a loud bang and escape of hot air from the filter silencer.

10 Mothballing the turbocharger 10.1 Taking out of operation for up to 12 months

Condition of engine lubricating oil

The turbocharger normally remains mounted on the engine. Preservation for storage of a turbocharger depends on the condition of the lubricating oil:

If the total acid number (TAN) is lower than 2 mg KOH/g no measures have to be taken.

If the engine lubricating oil is replaced by storage oil before the shut-down and this is circulated by the prelubrication pump, no measures have to be taken. Any remaining old engine oil will thus be flushed away and bearing sections largely protected against corrosion.

Storage preservation measures

If the total acid number (TAN) is greater than 2 mg KOH/g, the following storage preservation measures are necessary after a shut-down:

Remove turbocharger. Have rotor and bearing parts removed and refitted by an official ABB

Turbo Systems service station. Clean all parts. Oil machined, bright surfaces of steel and cast parts using anticorro-

sive oil. Refit complete turbocharger.

Rotating rotor in stack draught

If the rotor rotates as a result of the stack draught:

Install blind flange between compressor casing outlet flange and char-ge air duct.

10.2 Taking out of operation for more than 12 months If the engine is taken out of service, the following can be done with the turbocharger:

The turbocharger remains mounted on the engine. The turbocharger casing remains mounted on the engine, but the rotor

and the bearing parts are removed and stored separately. The turbocharger, either as a whole or in individual parts, is removed.

See section Shut-down for up to 12 months, under Storage preservation measures, for the measures always necessary when storing turbocharger parts.

If the turbocharger remains mounted on the engine, refer to section Shut-down for up to 12 months, under Rotating rotor in stack draught.

If the whole turbocharger is removed or the turbocharger is re-assembled next to the engine using the individual parts:

Close all turbocharger openings using wooden covers and paraffin pa-per.

Suitable storage locations are dry rooms only where the relative humidity is between 40-70% and no condensation can form.

Condition of stored turbocharger

Check stored turbocharger parts yearly for corrosion. If there are signs of rust: Clean parts thoroughly and renew corrosion

protection.

11 Disposal

Environmentally compatible disposal of turbocharger components

Disposal must be environmentally compatible, professional and in accor-dance with local regulations.

The turbocharger mainly consists of metal (cast-iron materials, steel, ni-ckel-steel alloys, aluminium, bearing brass).

Other components are: Non-metallic materials (filter components made of felt and polyethylene), lubricants (engine oil), electronic components (speed sensor and associated components), thermal insulation.

Dispose of metals as old metal for recycling. Dispose of non-metallic materials as waste. Dispose of lubricant left-overs as used / waste oil. Dispose of electronic components as electrical / electronic scrap.

Handling damaged thermal insulation Damaged thermal insulation can burden the air with dust. The glass fi-bres can cause mechanical irritation of the eyes, skin and respiratory tracts.

Prevent dust from being produced. Remove dust with a suitable vacuum cleaner. Wear respiratory mask as protection against particles (P1 or P2

mask). Wear leather protective gloves. Wear close-fitting safety goggles.

Dispose of thermal insulation as special waste.
