Turbocharger/Vtr564 Turbo Rotor Complete/Turbo Replacement Parts

/ VTR series marine turbocharger features:

VTR564series turbocharger rotor assembly / rotor complete belongs to one part of the /VTR 4 series exhaust gas turbocharger. The /VTR series marine turbocharger is created for two-stroke, low-speed and four-stroke, medium-speed heavy-duty diesel engines. The engine power output is from 700 kW to 18,500 kW per turbocharger. VTR series turbocharger has been widely applied to marine propulsion engines (esp. at part load), stationary power plants and units burning heavy oil and in continuous operation. The advantages are as following:

• Optimum engine perforce in part-load operation
• The optimum match with all types and designs of engines due to the modular concept adoption
• Connectors on the compressor side allow water cleaning during operation
• External bearing
• Integrated lubrication system
• The rotor shaft can be removed without distling the gas ifolds, or pulling of the compressor wheels
• Low friction losses of the external antifriction bearings
• The VTR 4 series is capable of high pressure-charging, the pressure ratio from 3.7 even to 4.2.

Brief introduction of The 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.
