1. Insufficient grease or oil lag
(1) When the turbocharger speed and engine load increases, the turbocharger oil fuel supply must also increase
plus, because high engine load operation, turbocharger speed is quite high, even if it were not for a summarize few seconds of the turbocharger bearing oil supply shortage will outcome in bearing damage.
(2) the replacement of oil and oil filter, use pre-filled with clean oil filter, for the first time after start the engine should start after the engine idle long enough to reserve running until the engine oil pressure permanence after expedited, or turbocharger bearings during startup may be due to a lack of lubrication and damage.
(3) When the engine is in tilt mode of operation (partial load or full load operation), the oil is too low or whether the oil inhalation of air, it will cause lower oil pressure, even a short period to make the turbocharger is also likely damage due to lack of lubricant.
2. External debris or sediment into the lubrication system
call with stolen goods or sediment of oil on the bearings of the turbocharger for diesel engine wear and harm than the much extra serious harm to the bearing, because the turbocharger speed is much higher than the engine speed. If the turbocharger mar occur, you should ascertain out the reason and to remove the oil stolen goods, or even put new pressure appliance damage tin occur, amplify and may damage the engine. When mingled with oil in the stolen goods in larger motes, ample to plug the turbocharger interior oil passages, the turbocharger will be occasioned by damage due to absence of lubricant.
in the oil and oil filter replacement, in the circumstance of conditions among the engine oil can be extracted oil specimens for thinking, which will help prevent the damage; should follow directions provided on the replacement term replacement of oil filter, must not be arbitrarily stretched.
3. Oil oxidation or deterioration of engine oil oxidation or deterioration
after the formation of sludge deposited, sludge will affect the rendition and turbocharger life;
the sludge while the oil will also affect the state of solemn engine life. The turbocharger shaft circulation games on the housing wall, beating the oil,
GHD NZ, fuel sludge that is accompanied to and deposited in the housing wall when the sludge deposits turbine side effects also much cervix bearing oil return while deposited on the turbine side bearing sludge deserving to tall temperature exhaust gas coming into creature singed hard coking when coke behind peeling off and make the turbine side daily bearing wear, and wear and tear before the seal leakage will happen. If it is base
turbocharger turbine side has oil leak, you must check the return pipe and turbocharger diesel engine vent pipe is blocked,
GHD IV Straighteners, and merely after these troubleshooting supercharger to work.
is due to the formation of sludge deposits and deterioration caused by oxidation of diesel oil, oil oxidation and deterioration caused by the fundamental reason is the engine overheating, from among the piston and the cylinder wall by the gas too much oil miscellaneous with diesel oil, cooling water leak into the engine oil, oil, and the improper selection of oil changes along to the specified time limit and so on.
4. External foreign matter into the engine intake or exhaust system
turbocharger turbine and compressor impellers are rotating by high speed, once the outer foreign matter into the engine intake and exhaust system will damage the impeller ; small objects (such as sediment) will erode the impeller blades lead to changes in air angle; massive and hard objects will cause foliage breakdown; soft thing (such as cotton) will be facing the direction of rotation of the impeller blades on the volume .
If there is damage to the external foreign objects leaving the impeller will damage the all turbocharger, it must be completely replaced. Typically, the compressor impeller damage due to the air filter in the embedded metal or replace the filter at the intake pipe into the debris to be sucked into the compressor due to, if not replace the filter or air intake pipe does not exclude debris, damage is presumable to continue for the new turbocharger.
5. Operating temperature is too high
general, the high temperature caused by heat from the engine of the row of gas (exhaust), exhaust gas temperature will be instantly or indirectly damage the turbocharger. Direct damage, that is due to high temperature so that overheating of the turbocharger in the middle of the shell, and to the turbine shell stuff by corrosion or deformation; turbine exhaust temperature is too high will cause shell cracking. Indirect damage, that is, when exhaust gas temperature is too high, the accessory heat will exhaust turbocharger rotor convergence haste, and higher than the chart speed under the conditions of work, if this happens, the compressor impeller as once or reiterated high load of stress and cracking, turbine impeller will also be due to stuff strength at lifted temperatures and turbine speed addition and reduce cracking. Exhaust gas temperature caused by the possible reasons are: not the engine air-fuel ratio, engine timing problems, are slitting emissions, exhaust gas oxygen sensor problems, or engine control system and additional problems.
In short, the exhaust gas turbocharger go is portrayed by high temperature and high-speed conditions in the go, to ensure it works properly, use the following should be considered:
(1) of the newly opened or equitable upkeep agreeable supercharger, ahead using the applying in hand struck the rotor, retard as lax and do no favor namely
normal voice; at work if given a keen sound should stop instantly. If the turbocharger vibration occurs, may be due to the air compressor impeller,
GHD MK4 Gold Straighteners, bearings or damage caused by the turbine impeller, need to be mended for.
(2) must assure namely the compressor inlet cleaning, strengthening the climate filter washing. Not grant exotic matter apt enter the compressor and turbine; apt discourage dust collection aboard the impeller,
GHD Blue Butterfly 2011, otherwise it will dilute the compressor efficiency.
(3) must ensure a authentic turbocharger lubrication oil to clean and oil pressure to regular, not too high or too low oil temperature, oil pipe joints ought be sealed,
GHD IV Salon Straighteners, not a drop phenomenon,
GHD Classic Straighteners, booster use ought be lubricated before (through the turbocharger oil into the pipeline by adding quantitative).
(4) should strictly control the turbine inlet temperature, this must be provided to accommodate the engine fuel system, fuel supply shall be arbitrarily changed.
(5) should all listen to check the featuring of the turbocharger; if the turbocharger is working correctly, just after the shutdown diesel turbocharger rotor can persist to run a decisive time.
(6) of the joining pipe should be convened correctly, when dismantling shall be arbitrarily change and should be effectively sealed to ensure reliable articulation.
(7) diesel engine is started, should ensure adequate lubrication of the turbocharger; engine shutdown before fleeing at sleepy speed 3 ~ 5min, so that the oil will heat away to shirk scald out the bearing seal ring or biting decease and distortion of the bearing shell
