Diesel Generator Tech

Exhaust turbocharger is actually an air compressor that increases air intake through compressed air. It uses the inertial impulse of exhaust gas from the engine to push the turbine in the turbine chamber, the turbine drives the coaxial impeller, the impeller compressed the air from the air filter pipe to pressurize it into the cylinder. The increased air pressure and density entering the cylinder can burn more fuel, accordingly increase fuel amount and adjust engine speed, which can increase the output power of the engine. Turbochargers are based on the principle of forced induction. It is the process of forcing compressed air into the intake for combustion. PARTS OF TURBOCHARGERS A Turbocharger consists of - 1.) COMPRESSOR HOUSING 2.) COMPRESSOR WHEEL 3.) BEARING 4.) OIL SEALS 5.) SHAFT 6.) TURBINE WHEEL 7.) TURBINE HOUSING The middle part whole part together is called a turbocharger cartridge. The compressor wheel and the turbine w...

Assembly of diesel generator set exhaust turbocharger 1. With the compressor end of the middle casing facing up, insert the spring retaining ring into the inner ring groove of the bearing end of the compressor. Then place the floating bearing with the oil on it and the thrust ring into the other spring retaining ring. When installing a floating bearing, turn the end with the oil groove on the side. After each spring snap ring is installed, check that the snap ring is fully inserted into the ring groove. 2. With the turbine end of the intermediate casing facing up, the spring snap ring, the floating bearing, and the thrust ring are sequentially loaded into the turbine end bearing hole in the same order as in the step 1. When installing the floating bearing, care should be taken to raise the end of the oil groove on the side. 3. Two rings made of thin wire are placed over the fingers, and the two elastic sealing rings are opened and inserted into the turbine rotor shaft se...
