Ship Turbocharger Rotor Shaft Excellent Anti Accident Ability Customized Machining
A rotor shaft assembly for use in turbochargers includes a metal shaft having a generally cylindrical female cavity therein concentrically distributed about the axis thereof; and a solid hubbed ceramic turbine wheel having a male stub shaft insertable into the female cavity. The axis of the male stub shafted ceramic turbine is coextensive with the axis of the shaft and the stub shaft is mated with the female receptacle and joined by an adhesive. A turbocharger includes a rotor-shaft assembly of the above-described type, in which the metal to ceramic adhesive joint is located in the turbocharger center housing.
- It consists of single stage mixed-flow turbine, centrifugal compressor, external engine lubricating oil system.
- it can be matched with high-speed diesel engine and gas engine of 500-3000kw.
- cooled & uncooled bearing casing design.
- The constant pressure mixed turbine is used to increase the volume flow through the nozzle ring with the pulse application.
- The compressor wheel adopts after sloping shunt blades and provide three different periods of pressure.
- The overall efficiency of turbocharger is 62%-64%, the maximum pressure ratio is 4.5.
- It is compact structure, easy to maintain and widely used in marine main engines, marine auxiliary machines, generating sets, railway locomotives and other application areas of diesel engines.
Turbocharger design features:
bladed shaft belongs to the turbocharger. The turbocharger is for large medium-speed diesel and gas engines, with a power output range from2,500kW to 12,500kW.
-
Turbine: The turbocharger is axial turbine for high efficiencies and high volume flow rates.
-
Compressor: The compressors ensure the high volume flow rates which allow optimized matching to different engine applications. Its single-piece, splitter-bladed aluminum alloy wheels with backswept blades ensure high efficiencies and wide compressor maps. its pressure ratio is from 4.2 up to 5.0 based on different design.
-
Bearing: The bearing assembly lubricated directly by the engine lube oil system, plain bearings can run up to 36,000 hours before being overhauled.

Brief introduction of Marine turbocharger:
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%.
