Turbocharger causes of damage

1. Insufficient grease or oil delay
(1) When the turbocharger speed and engine load increases, the turbocharger oil fuel supply must also boost
plus, for high engine load operation, turbocharger speed is quite high, even if only a terse 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 begin the engine should start after the engine lazy long enough to reserve fleeing until the engine oil pressure stability after hastened, or turbocharger bearings during startup may be due to a lack of lubrication and damage.
(3) When the engine is in tilt mode of action (prejudiced load or full load operation), the oil namely too cheap or whether the oil breath of air, it will reason lower oil oppression, even a short time apt make the turbocharger is too feasible harm deserving to absence of lubricant.
2. External debris or sediment into the lubrication system
shriek with stolen goods or sediment of oil on the bearings of the turbocharger for diesel engine wear and damage than the much extra serious damage to the bearing, because the turbocharger speed is much higher than the engine speed. If the turbocharger damage occur, you should detect out the reason and to clear the oil stolen goods, or even put new pressure appliance damage tin occur, develop and may damage the engine. When mixed with oil in the stolen goods in larger molecules, enough to plug the turbocharger inner oil passages, the turbocharger will be caused by damage due to lack of lubricant.
in the oil and oil filter replacement, in the circumstance of conditions within the engine oil can be extracted oil examples for analysis, which will help prevent the damage; should follow directions provided on the replacement term replacement of oil filter, must not be arbitrarily amplified.
3. Oil oxidation or deterioration of engine oil oxidation or deterioration
after the formation of sludge deposited,GHD MK4 Gold Straighteners, sludge will affect the representation and turbocharger life;
the sludge when the oil will also influence the state of serious engine life. The turbocharger shaft rotation games on the housing wall, beating the oil, oil sludge that is attached to and deposited in the housing wall when the sludge deposits turbine side effects too much neck bearing oil return when deposited on the turbine side bearing sludge due to high temperature exhaust gas coming into being roasted hard coking when coke after peeling off and make the turbine side magazine bearing wear, and dress and cut before the seal leakage will occur. If it is base
turbocharger turbine side has oil leak,GHD Straighteners, you must check the return pipe and turbocharger diesel engine vent pipe is blocked, and only 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 cause is the engine overheating, from between the piston and the cylinder walls by the gas too many oil mixed with diesel oil, cooling water drip into the engine oil, oil, and the unsuitable 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 at high speed, once the external foreign matter into the engine intake and exhaust system will damage the impeller ; small objects (such as sediment) will corrode the impeller blades guide to changes in wind angle; colossal and hard objects will cause foliage breakdown; soft object (such as cotton) will be facing the instruction of rotation of the impeller blades on the volume .
If there is damage to the external foreign objects leaving the impeller will damage the whole turbocharger, it must be entirely 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 eliminate debris,GHD IV Dark Straighteners, damage is possible to continue for the new turbocharger.
5. Operating temperature is too lofty
common, the high temperature caused by heat from the engine of the row of gas (exhaust),GHD Benefit Straighteners, exhaust gas temperature will be directly or indirectly damage the turbocharger. Direct damage, that is due to high temperature so that overheating of the turbocharger in the navel of the shell, and to the turbine shell substance 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 gathering haste, and higher than the design speed below 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 substance strength at hoisted temperatures and turbine speed increase and reduce cracking. Exhaust gas temperature caused by the possible reasons are: not the engine air-fuel percentage, engine timing problems, are cutting emissions, exhaust gas oxygen sensor problems, or engine control system and additional problems.
In short, the exhaust gas turbocharger work is represented by high temperature and high-speed conditions in the work, to ensure it works properly, use the following should be considered:
(1) of the newly opened or just upkeep agreeable supercharger,GHD IV Salon Straighteners, ahead using the petition in hand struck the rotor, check for lax and do no favor is
regular voice; by go if given a sharp sound should stop swiftly. If the turbocharger vibration occurs, may be due to the air compressor impeller, bearings or damage caused by the turbine impeller, need to be altered for.
(2) have to ensure namely the compressor inlet cleaning, reinforcing the air percolate washing. Not allow exotic stuff to enter the compressor and turbine; to prevent dust collection aboard the impeller, otherwise it will depress the compressor efficiency.
(3) must ensure a reliable turbocharger lubrication oil to clean and oil pressure to normal, not too high or too low oil temperature, oil pipe joints should be sealed, not a trickle phenomenon, booster use should be lubricated before (via the turbocharger oil into the pipeline by adding quantitative).
(4) should strictly control the turbine inlet temperature,GHD Precious Gift Set, this must be provided to adapt the engine fuel system, fuel supply shall be arbitrarily changed.
(5) should forever listen to check the functioning 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 interlocking pipe should be assembled correctly, when dismantling shall be arbitrarily change and should be effectively sealed to ensure authentic connection.
(7) diesel engine is started, should ensure ample lubrication of the turbocharger; engine shutdown before running at idle speed 3 ~ 5min, so that the oil will heat away to avoid flame out the bearing stamp ring or biting necrosis and distortion of the bearing shell
