© Copyright 2020 . All rights reserved. HZTL2412_EN Rev.G March 2020 Operation Manual / TPS44-F.. - TPS61-F.. 1 Preliminary remarks / 1.2 Layout and function Mode of operation The turbocharger is a turbomachine consisting of the following main components: ◼ Turbine ◼ Compressor These are mounted on a common shaft. Exhaust gases from the diesel or gas engine flow through the turbine casing (10) and the nozzle ring (9) to impinge on the turbine (7). The turbine (7) uses the energy contained in the exhaust gas to drive the compressor wheel (13). The compressor draws in fresh air, compresses it and then forces it into the engine's cylinders. The exhaust gases escape into the ambient air through the exhaust gas pipe, which is connected to the gas outlet flange (8). The air, which is necessary for operation of the diesel or gas engine and is compressed in the turbocharger, is drawn into the compressor wheel (13) through the suction branch or filter silencer (1). It then passes through the diffuser (3) and leaves the turbocharger through the outlet 3 1 on the compressor casing (2). 1 / The rotor runs in two radial plain bearings (6), which are located in the 5 e bearing flanges (11/12) between the compressor and the turbine. The g a axial thrust bearing (5) is located between the two radial plain bearings. P The bearings are connected to a central lubricating oil duct which is sup plied by the engine's lubricating oil circuit. The oil outlet is always at the lowest point of the bearing casing (4). © Copyright 2020 . All rights reserved.

The maintenance points described here are differentiated as follows: ◼ Cleaning during operation: – Compressor – Turbine and nozzle ring. ◼ Mechanical cleaning of individual components: – Filter silencer – Casings, diffuser, nozzle ring – Cartridge group: Compressor, turbine CAUTION Risk of damage during mechanical cleaning 3 If mechanical cleaning is carried out too often, this can lead to damage 1 1 and corrosion on the components. / 5 ► If cleaning during operation is not sufficient to achieve acceptable 4 e values regarding thermal load and engine performance, mechanical g a cleaning of certain spots can be carried out. P ► Perform mechanical cleaning, especially of the cartridge group, only once within the service interval. To allow you to observe the standard service intervals and to maintain a high turbocharger efficiency, ABB Turbocharging recommends that the cleaning procedure be carried out during operation. This allows the thermal load of the engine to be kept low while ensuring maximum fuel efficiency. ► Dispose of dirty water and cleaning agents in an environmentally compatible manner, professionally and in accordance with valid local regulations. © Copyright 2020 . All rights reserved. HZTL2412_EN Rev.G March 2020 Operation Manual / TPS44-F.. - TPS61-F.. 5 Maintenance / 5.2 Cleaning the compressor during operation 5.2 Cleaning the compressor during operation General The contamination of the compressor stage (compressor wheel, wall in sert and diffuser) depends on the degree of purity of the air that is drawn in. Deposits can form in the flow channels if salt, oil mist, exhaust gas or dust are sucked in with the air. Consequences of contamination: ◼ Impaired compressor efficiency ◼ Higher exhaust gas temperatures ◼ Increased fuel consumption ◼ Increased rotor unbalance Periodic cleaning of the compressor during operation prevents or delays any major increase in contamination. It does not, however, replace the regular service work, during which the turbocharger is completely dis mantled and the compressor is cleaned mechanically. NOTICE 3 If the coating of dirt is very thick and hard, the compressor can only be 1 1 cleaned manually when disassembled. This cleaning must be carried out / 6 by an ABB Turbocharging Service Station. 4 e g a P Cleaning interval The interval between periodic cleaning is very dependent on the operat ing conditions. In general, cleaning should be carried out every 25 ... 100 operating hours. Should the specified cleaning intervals prove incompatible with engine operation, please contact ABB Turbocharging. © Copyright 2020 . All rights reserved. HZTL2412_EN Rev.G March 2020 Operation Manual / TPS44-F.. - TPS61-F.. 5 Maintenance / 5.2 Cleaning the compressor during operation Cleaning method Cleaning the compressor while in operation is carried out as wet clean ing. This cleaning method is tested and approved by ABB Turbocharging. Principle of wet cleaning To clean the compressor stage during operation, water is injected in front of the compressor wheel through an injection pipe fitted in the fil ter silencer or the suction branch. The water does not act as a solvent, but the contamination deposit is re moved by the mechanical impact of the droplets. This is a very suitable process, provided that the degree of contamination is not too high. CAUTION Corrosion and deposits when cleaning Damage and impairment of turbocharger parts due to salt water and cooling water additives ► Don't use salt water for cleaning, but only clean fresh water. CAUTION 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 3 1 prevents uncontrolled volumes of water entering the turbocharger and 1 / engine, which can lead to serious damage. 7 4 e g V-engines In the case of V-engines with several turbochargers on each engine, we a P recommend parallel cleaning of the compressors. This cleaning process is faster and the risk of turbocharger surging is reduced. Sequential charging 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. © Copyright 2020 .

HZTL2412_EN Rev.G March 2020 Operation Manual / TPS44-F.. - TPS61-F.. 5 Maintenance / 5.3 Turbine cleaning during operation 5.3 Turbine cleaning during operation The combustion of fuels such as heavy fuel oil (HFO) in diesel engines produces contamination of the turbocharger's turbine components. In combination with a high exhaust gas temperature, poor quality fuel can lead to particularly hard deposits on the nozzle ring and especially on the gas outlet flange. ABB Turbocharging recommends the use of fuels with low ash, sulphur, sodium and vanadium contents. Consequences of contamination: ◼ Poor turbine efficiency ◼ elevated exhaust gas temperatures ◼ higher charging and ignition pressures as turbocharger speed rises ◼ lower engine performance. ◼ After stopping the engine, the rotor can become stuck in contamina tion deposits. Experience with turbocharger operation shows that the intervals between overhauls can be extended if cleaning while in operation is car ried out periodically. Wet cleaning the turbine, as described below, 3 1 1 should be used for 4-stroke applications when there are heavy deposits / from, for example, HFO. 0 5 e Under no circumstances is periodic cleaning of the turbine during opera g a tion a substitute for the service work carried out when the turbocharger P is completely dismantled and cleaned mechanically. Turbines which are very heavily contaminated cannot be cleaned this way any longer. In this case, the contaminated components must be mechanically cleaned by an ABB Turbocharging Service Station. NOTICE Regular cleaning Regular turbine cleaning during operation prevents or delays excessive build-up of contamination. Cleaning intervals The interval between periodic cleaning is very dependent on the operat ing conditions. In general, cleaning should be carried out every 50 to 200 operating hours. NOTICE Cleaning intervals Should the specified cleaning intervals prove incompatible with engine operation, please contact ABB Turbocharging. © Copyright 2020 . All rights reserved. HZTL2412_EN Rev.G March 2020 Operation Manual / TPS44-F.. - TPS61-F.. 5 Maintenance / 5.3 Turbine cleaning during operation Cleaning method Turbine components are cleaned during operation by using the wet cleaning method described below. This cleaning method is tested and approved by ABB Turbocharging. The turbine casing design and the type of turbine casing seal are decis ive for the choice of cleaning method. NOTICE Approval by engine manufacturer The prerequisite for wet cleaning is that the engine manufacturer ap proves the method and his instructions are followed. 5.3.1 Wet cleaning methods Process with short water injection time (3 x 30 seconds cleaning) The cleaning process with short water injection time is used for tur bocharger designs without additional sealing by means of C-rings. The process is based on the principle of thermal shock in combination 3 1 with a subsequent flushing phase. 1 / 1 5 e Process with long water injection time (10 minutes cleaning) g a P The cleaning process with a long water injection time is used for tur bocharger designs with additional sealing by means of C-rings. Based on a 10-minute injection phase, this cleaning process utilises the water solubility of the dirty deposits. NOTICE Choice of cleaning method If you need information about the choice of cleaning method (short / long), you can contact the engine builder or an official ABB Turbochar ger service station. © Copyright 2020 .

CAUTION Maximum temperature in front of turbine during cleaning When cleaning, the temperature in front of the turbine will rise and can heavily stress the material of turbine components. The temperature at the turbine inlet can be up to 100 °C higher than the exhaust gas tem perature after the cylinder. This should be taken into consideration when setting the operating point before cleaning. ► Don't exceed maximum temperature in front of turbine when clean ing. 3 1 1 / CAUTION 2 5 e Impermissible thermal stressing and flooding of the turbine g a P Smaller volumes of water can result in poor cleaning. Larger volumes of water lead to impermissible thermal stressing of the turbine compon ents and can cause flooding of the turbine. ► Be absolutely sure to observe turbine cleaning parameters. NOTICE V-engines In the case of V-engines with several turbochargers on each engine, we recommend parallel cleaning of both turbochargers. This cleaning pro cess is faster and the risk of turbocharger surging is reduced.
