The definition of  turbo compressor wheel / compressor impeller:

• The compressor wheel/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.

Brief introduction of Marine turbocharger:

Moban 3-1 independently: The marine turbocharger, also known as exhaust gas turbocharger, is the main equipment in the diesel engine boosting system. It consists of a single-stage exhaust gas turbine and a centrifugal compressor. They are mounted on the same shaft to form the moving part of the marine turbocharger/exhaust gas turbocharger - the rotor. The function of the marine turbocharger/exhaust gas turbocharger is to use the diesel exhaust energy to drive the turbine to drive the compressor on the coaxial to increase the air pressure into the cylinder, so that the diesel engine power is greatly improved. The exhaust turbocharger approximately doubles the power of the diesel engine, but its weight is only increased 10%.
