3.3 does not promptly remove sludge

Supercharger after prolonged use, dust in the air with mist forming sludge, and gradually gathered in the shell imported supercharger access to the impeller housing and without gaps or leaves contact with the supercharger shell and friction , supercharger from the vibration of the rotor shaft, the shaft increased wear. Regular checks should be promptly removed sludge.

3.4 exhaust temperature is too high

The supercharger failure of the engine fuel system, such as supply delays, excessive supply, or exhaust nozzle Diyou phenomena such as gate leakage can lead to the exhaust temperature is too high, thereby enabling the import of the turbine blade Burning deformation. Exhaust temperature too high can make the turbine oil-sealed carbonation, and the turbine-bearing local overheating (check-pressure gas turbine bearings normal and the firing-bearing blue or black) and sealed bearings caused premature Failure.

Shedding 3.5 Nut

Nut in operation detached from the shaft skidded off the compressor impeller, smashed, damaged turbocharger scrapped. First, the failure of tightening torque nuts enough, and the second is not installed on the nut thread compound. Compressor impeller and rotor shaft gap is used with a certain amount of the nut torque will be fixed with its strict torque, torque shaft bending over to the General Assembly, resulting in reduced accuracy of the rotor shaft balance, vibration Supercharger too large, too small or torque on the plastic screw, nut will work in the loose and even damage to the impeller spondylolisthesis.
