T- VTR304 Turbo Compressor Wheel For T- Marine Propulsion Engines Turbocharger Spare Parts

T- / T- VTR series marine turbocharger features:

T- VTR304 turbo compressor wheel (also called compressor impeller) is one part of T- / T- VTR 4 series marine turbocharger with the features as below:

1. The T- VTR series turbocharger is developed to match with two-stroke low-speed and four-stroke medium-speed heavy duty diesel engine and gas engine.
2. The engine power output range from 700 kW to 18,500 kW per each T- VTR turbocharger.
3. The T- VTR series turbocharges is consisted of single-stage axial turbines and radial compressors.
4. Easy maintained external bearings.
5. The T- VTR 4 series is capable of high pressure-charging, the pressure ratio from 3.7 even to 4.2.
6. Uncooled gas casings are available which can be an alternative to water-cooled gas casing.
7. The rotor runs in spring-mounted roling-contact bearings, and each bearing has its own lubrication system and oil cooling system.
8. The rotor shaft can be removed in four easy steps without disconnect any air, gas or water pipes.
9. The T- VTR series is modular type of design, which ensures the turbine baldes, nozzle rings, comperssor wheels and diffusers with various casing configurations to be optimum matched with all engine types.
10. The T- VTR series turbochargers are widely used in marine propulsion engines, especially at part load, and in stationary power plants, on units burning heavy oil and in continuous operation.

Introduction of Turbo Compressor Wheel:

T- VTR304 Turbo Compressor Wheel (compressor impeller) is made 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. To extend the life, air temperatures must be reduced.
