T- ABB Marine Turbocharger Rotor Assembly / T- RR151 Turbo Rotor Complete For Small Size High Speed Diesel Engine

T- ABB / T- RR series turbocharge design features:

 T- RR151 turbo rotor complete (also called rotor assembly) belongs to T- ABB / T- RR series turbocharger. The T- RR series turbocharger is a lightweight, low-cost turbocharger with robust design, offering high efficiency, high gas-inlet temperature capability and good compressor characteristics. The T- ABB / T- RR turbocharger is used on diesel marine engine,  rail as well as earthmoving and mining equipment.

• High- output range from 500 kW to 1800 kW per turbocharger;
• Compressor pressure ratios: up to 3.5;
• High efficiency and small size;
• Lower fuel consumption
• The T-RR series turbocharger is equipped with pressure lubricated internal bearings, externally mounted "mixed flow" turbines and radial compressors;
• The T-RR series turbochargers are lubricated via the oil systme of the engine using standard oil filters;
• .The T-RR series turbochargers are used on high-speed diesel engines and on gas engines.

The composing of turbocharger rotor assembly / rotor complete:

The turbocharger rotor assembly / rotor complete consists of compressor impeller, blade shaft or turbine shaft and turbine blade. The compressor impeller is of aluminium alloy or the more expensive titanium. Manufactured from a single casting it is located on the rotor shaft by splines. Aluminium impellers have a limited life, due to creep, which is dictated by the final air temperature. Often the temperature of air leaving the impeller can be as high as 200°C. The life of the impeller under these circumstances may be limited to about 70000 hours. The turbocharger rotor shaft is equipped with components such as a compressor and a turbine impeller, and has a complicated structure and a large weight.
