T- Turbocharger / T- TCR12 Turbocharger Rotor Assembly For Heavy Fuel Oil, Marine Diesel Oil, Biofuel And Gas Engine

T- / T- TCR series turbocharger features:

T- TCR12 Turbocharger Rotor Assembly (also called rotor complete) belongs to the part of T- / T- TCR turbochargers, which were created to address the very special challenges faced by Heavy Fuel Oil, Marine Diesel Oil, biofuel and gas engines. Products are available for the entire engine power range, from 350 kW to 7MW per turbocharger.
T- / T- TCR turbochargers are IMO Tier III compliant, and represent a robust, versatile modular platform– suitable for a wide variety of high-speed, medium-speed and low-speed engine applications.

• Engine outputs from 350 kW to 7M;
• Radial flow design;
• Increased efficiency due to improved compressor wheel and turbine design;
• Constant and pulse pressure turbocharging;
• Low moment of inertia for best dynamic behavior;
• New compressor wheel fixation for easy servicing;
• Un-cooled casings;
• Pipe-less design with integrated oil inlet and oil drain;
• No sealing air required;

Applications:

Marine propulsion, excavators, locomotives, power generation, off-road vehicles, machanical drive, mining, marine gensets.

The composing of T- TCR12 turbocharger rotor assembly (rotor complete):

The turbocharger rotor assembly / rotor complete consists of compressor impeller, blade shaf/turbine shaft/rotor shaft and partition wall complete.
The compressor impeller is of aluminium alloy or the more expensive titanium. ufactured 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. To extend the life, air temperatures must be reduced. One way of achieving this is to draw the air from outside where the ambient air temperature is below that of the engine room. Efficient filtration and separation to remove water droplets is essential and the impeller will have to be coated to prevent corrosion accelerated by the possible presence of salt water.

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. If the ship is parked for a long time, the turbocharger rotor will be bent and deformed due to the long-term non-operating self-weight, which will break the matching gap between the rotor and the casing, the gas seal and the casing, and the rotor will be lost. In severe cases, the rotor is difficult to rotate and the friction is severe. A large centrifugal force is generated during operation to cause the supercharger to vibrate.
